The present disclosure relates generally to tooling operable to form material (e.g., metal) into desired shapes, and more specifically to roll forming machinery employing sets of pairs of forming rollers, and including those that employ turret assemblies and/or cassettes of forming rollers, and to related articles and methods.
Roll forming involves the rolling of material (also referred to as a workpiece), typically metal material, into a desired cross-sectional shape. The material passes through consecutive pairs of roll tooling, typically referred to as forming rollers or rolls, the forming rollers of each pair of forming rollers cooperating with one another to perform incremental portions of forming or bending. The material is operated on by a sequence of pairs of forming rollers until the desired cross section is realized. Roll forming is usually continuous with the material fed from a coil, or feed from an in-line fabrication stage.
A variety of cross-sectional profiles can be produced on a roll former, but each cross-sectional profile requires its own custom roll tooling. The roll tooling (e.g., forming rollers) is mounted on shafts which are typically held in bearing stands. The shafts are powered by mechanical drive systems. Typically, upper roll shafts are adjustable to provide a range of clearance between the upper and lower forming rollers of each pair to allow various thickness materials to be processed, as long as the same cross-sectional profile is desired.
Conventionally, roll forming machinery is available in two general styles. A first style employs straddle mounts, where bearing stands straddle the tooling. A second style employs a cantilever design, where both bearing stands are on a same side of the roll tooling. The straddle design is normally used for wider products, and for forming heavier materials. The cantilever design is better suited for narrow products with lighter loading.
If various cross-sectional profiles are produced on the same roll forming machinery, the roll tooling must be changed for each cross-sectional profile. Changing roll tooling can be a time consuming process resulting in several hours of downtime as the roll tooling is changed, and while adjustments are made to fine tune the tooling positions of the roll tooling to obtain the required dimensions, and hence quality. Along with downtime, changing the roll tooling also incurs the cost of skilled mechanics or operators, as well as the production of scrap material on each changeover. It is noted that with respect to changeover, the cantilever style roll forming machinery may be preferable over the straddle style rolling forming machinery since the shafts and bearings do not have to be removed and the roll tooling can simply be slid off and the next set of roll tooling slid onto the shafts. The cantilever style saves some time on change over relative to the straddle style, but the changing the roll tooling is still time consuming with the cantilever style roll forming machinery.
There are situations where multiple cross-sectional profiles are produced on the same machine (e.g., up to 6 or 8 cross-sectional profiles) and there are multiple changeovers required on a daily basis to meet customer needs. If there are two or three changeovers per day, and 2 to 3 hours per changeover, total downtime per day can range from 4 to 9 hours per 24 hour day. In many instances, this is unacceptable so various approaches have been devised to limit such lost time. For example, some approaches employ rafts with a second set of stands and roll tooling that can be moved into position, or even in some cases a complete second roll former machine that can be moved in and out of a production line. These solutions are costly, take up space, and can usually only address two different product cross-sectional profiles.
A turret roll forming machine is described which includes at least one turret assembly that carries multiple rows of tooling (e.g., forming rollers), the turret assembly rotatable about an axis of rotation to selectively align a row of tooling with at least one of an input feed location or output feed location of a production line or of the turret roll forming machine.
The turret roll forming machine includes a frame, turret assembly rotatably mounted to the frame, a plurality of sets of pairs of forming rollers carried by the turret assembly, and a drive system including a motor and power drive train or transmission coupleable to drive selective sets of the pairs of forming rollers.
A power drive train or transmission may advantageously be positioned to be accessible from an exterior of the turret assembly, for example mounted or positioned on or outward of the exterior to the turret assembly. The drive system can include one or more motors, gears or sprockets, and/or chains. One of the benefits of this approach is that the turret assembly does not need to be disassembled in order to perform a changeover of roll tooling and/or to perform maintenance on the gears, bearings, or shafts of the transmission. This eliminates the time consuming and costly process of disassembling the turret assembly. In at least some of the illustrated and/or described implementations, the turret roll forming machine can advantageously be completely serviced without disassembly of the turret assembly.
Positioning the power drive train or transmission to be accessible from an exterior of the turret assembly advantageously allows a chain drive to be employed to drive the forming rollers. The use of a chain drive advantageously allows the freedom to design for differing rotational speeds of a top forming roller and a bottom forming roller of each pair of forming rollers. The ability to accommodate variations in speed between the rollers of any given pair is typically not possible with gear driven roll forming machines. This feature may be particularly advantageous when V-shapes are being formed in material. A pair of rollers that cooperate to form a V-shape in material will each have a respective diameter at the point of a respective V-shaped tip. Assuming the V-shaped is oriented with the open legs upward, and closed tip downward, the upper forming roller that forms the interior angle of the V-shape will have a smaller or tighter diameter than the lower forming roller that forms the exterior angle of the V-shape. If the two forming rollers are positioned tight together to form a sharp corner, there is a disparity in surface speed, which results in roll scuffing on the product being rolled and potential damage to the resulting product. Such can be alleviated using the described approach which permits differences in speeds between forming rollers of a given pair of forming rollers.
An additional advantage of positioning the power drive train or transmission to be accessible from an exterior of the turret assembly is that the power train components may be easily lubricated without risk of leaks or lack of lubrication on some portions thereof.
In at least some implementations, pairs of forming rollers may be provided as cassettes of forming rollers, which are removably coupleable to the turret assembly. Each cassette of forming rollers may carry one or more pairs of forming rollers, the forming rollers of each pair positioned to cooperate with one another to produce a change (e.g., bend, cut) in material passing therebetween. Successive pairs of forming rollers in a set may apply successive, and in some instances incremental changes in the material to produce a final desired cross-sectional profile. The use of cassettes of forming rollers may advantageously allow the turret roll forming machine to be quickly and easily reconfigured to produce a desired cross-sectional profile. Each cassette of forming rollers may carry one or more bearings, shafts, and/or shaft housings, worn or broken components of the transmission to be quickly and easily replaced, reducing downtime and cost of repair. The cassettes are preferably preassembled, facilitating quickly exchange.
One of the advantages of positioning the power drive train or transmission to be accessible from an exterior of the turret assembly and/or of the cassettes is that a changeover can be accomplished in minutes rather than hours, that a machine operator could perform the changeover and would not require a skilled technician, and that virtually no scrap would be created on each changeover.
In at least some implementations, the turret assembly is a unitary structure, rather than being a bolted assembly. For example, the turret assembly may be a weldment (i.e., one or more parts welded together) or may be a cast or extruded single-piece construction. This approach advantageously provides more rigidity and strength then bolted turret assemblies, and eliminates the risk of bolts vibrating loose. Improved rigidity and strength reduces flexing, thereby advantageously increasing accuracy of roll forming operations.
In at least some implementations, a production line may include one or more (e.g., ten) instances of turret roll forming machines at one or more respective roll stations, for example spaced successively along the production line. For example, to obtain more than, for example, four (4) different cross-sectional profiles, two or three turret assemblies could be arranged in tandem to achieve 4, 8 or 12 or more sets of preset tooling, for instance eliminating or reducing time lost in changeovers.
In at least some implementations, a master turret or carousel may carry a plurality of turret assemblies. The master turret or carousel coupled be rotated about a respective rotational axis to select a turret assembly with a desired set of tooling (e.g., set of pairs of forming rollers), and the selected turret assembly rotated about a respective rotational axis to align the desired set of tooling with at least one of an input feed location or output feed location of a production line.

The roll forming machine 100 includes a frame 102; a turret assembly 104; a plurality of sets 106a, 106b, 106c, 106d (four sets shown, collectively 106) of one or more pairs 108a, 108b (four pairs per set illustrated, only two pairs called out in
The frame 102 may have a large variety of shapes, sizes and/or forms. In the illustrated implementation, the frame 102 includes a front rectangular end 118 (called out in
The turret assembly 104 has a turret rotational axis 136 (shown in
In the illustrated implementation, the sets 106 of one or more pairs 108 of forming rollers 110 includes four distinct sets, a first set 106a of one or more pairs 108 of forming rollers 110, a second set 106b of one or more pairs 108 of forming rollers 110, a third set 106c of one or more pairs 108 of forming rollers 110, and a fourth set 106d of one or more pairs 108 of forming rollers 110, Other implementations may include less than four sets 106 or more than four sets 106 of pairs 108 of forming rollers 110. The pairs 108 of forming rollers 110 of each set 106 are sequentially arranged extending along the turret rotational axis 136, the forming rollers 110 of the each set 106 laterally spaced outwardly from the turret rotational axis 136 in a respective lateral direction (e.g., forming rollers 110 of the first set 106a are spaced laterally outwardly in a first lateral direction 138a (illustrated in
The turret assembly 104 has been illustrated with a substantially square profile, with two of the sets 106a, 106d of the pairs 108 of forming rollers 110 diametrically opposed to one another across the turret rotational axis 136 and the other two of the sets 106b, 106c of the pairs 108 of forming rollers 110 diametrically opposed to one another across the turret rotational axis 136. Such is not intended to be limiting. Some implementations may include only two sets 106 of the pairs 108 of forming rollers 110 diametrically opposed to one another across the turret rotational axis 136. Other implementations may have a hexagonal profile with six sets 106 of the pairs 108 of forming rollers 110 with pairs of the sets 106 diametrically opposed to one another across the turret rotational axis 136, or even an octagonal profile with eight sets 106 of the pairs 108 of forming rollers 110 with pairs of the sets 106 diametrically opposed to one another across the turret rotational axis 136. Other implementations may employ an odd number of sets 106 of pairs 108 of forming rollers 110.
The forming rollers 110 of each pair 108 in a given set 106 are arranged to cooperate with one another to perform a respective rolling forming operation on material passing therebetween. The pairs 108 of forming rollers 110 of each set 106 are arranged relative to one another along the turret rotational axis 136 to successively perform respective roll forming operations as material sequentially passes through the pairs 108 of forming rollers 110 from a location of the input feed 116a to a location of the output feed 116b.
As explained herein and as best illustrated by the detailed view of
In at least some implementations, the transmission 114 is accessible from an exterior 140 (
In the illustrated implementation, the transmission 114 advantageously comprises a forming roller drive chain 142. The forming roller drive chain 142 (shown in
The forming roller drive chain 142 is preferably accessible from the exterior of the turret assembly 104 without dismantling of the turret assembly 104. The one or more transfer shafts 144a, 144b is preferably accessible from the exterior 140 of the turret assembly 104 without dismantling of the turret assembly 104. The main drive chain 146 is preferably accessible from the exterior 140 of the turret assembly 104 without dismantling of the turret assembly 104. The gear reducer 148 is preferably accessible from the exterior 140 of the turret assembly 104 without dismantling of the turret assembly 104.
The roll forming machine 100 may optionally include one or more chain guards 150 (show removed in
As best illustrated in
The turret assembly 104 may further comprise at least one shaft 162 that is coaxial with the turret rotational axis 136. In the illustrated implementation, the tube 158 is a cylindrical tube having the passage 160 extending longitudinally therethrough, and the at least one shaft 162 is received through the passage 160 of the tube 158 and extends out of both ends of the tube 158. A number of bearings 164 (e.g., ball bearings, cylindrical bearings, metal bearings, ceramic bearings, bearing races) are located at each end of the tube 158, and rotatable mount the tube 158 to the shaft 162 such that the tube 158 is able to rotate about the turret rotational axis 136 with respect to the shaft 162. The bearings 164 should be sufficiently strong to support the weight of the turret assembly 104 and any forces applied to the frame 102 via the turret assembly 104.
The shaft 162 is fixedly mounted to the frame 102 such that the shaft 162 does not rotate or translate with respect to the frame 102. The shaft 162 thereby supports the remainder of the turret assembly 104 from an upper portion of the frame 102. Brackets or other securement structures may be employed to secure the shaft 162 to the frame 102. Thus, the tube 158 is able to rotate about the turret rotational axis 136 with respect to the shaft 162 and frame 102.
As best illustrated in
The brackets 166 and the tube 158 are preferably a unitary structure, for example a weldment, or unitary single-piece construction casting. The brackets 166 and the tube 158 are preferably arranged such that, when each cassette 174 of forming rollers 110 is detachably coupleable to a respective pair of the brackets 166, the pair of brackets 166 and the respective cassettes 174 form a triangular structure (best shown in
The turret assembly 104 may include a number of ribs 176 that extend from the outer surface of the tube 158, and which extend along a length of the tube 158. The ribs 176 may include a number of attachment features 178 (e.g., holes, threaded holes, slots, pins).

Each cassette 174 of forming rollers 110 comprises a respective cassette frame 180 with a plurality of attachment points 194 (also interchangeably referred to or attachment features). The cassette frame 180 may hold or support or otherwise carry a first block 184a and a second block 184b. Each cassette 174 may include a first shaft 186a and a second shaft 186b rotatably mounted to the first block 184a and the second block 184b, respectively. Each cassette 174 may include a first chain sprocket 188a and a first forming roller 110a of a respective pair of forming rollers 110 coupled to the first shaft 186a to rotate therewith when driven, and a second chain sprocket 188b and a second forming roller 110b of the respective pair of forming rollers 110 coupled to the second shaft 186b to rotate therewith when driven. The first forming roller 110a and the second forming roller 110b are arranged to complementarily cooperate with one another to perform a respective rolling forming operation on material that passes between the first forming roller 110a and the second forming roller 110b. Each cassette 174 of forming rollers 110 may include retainers 198a, 198b (best visible in
Each cassette 174 of forming rollers 110 may further include a first number of bearings 190a, 190b (visible in

Each cassette 174 of forming rollers 110 may include retainers 198a, 198b (best visible in
The respective cassette frame 180 of each cassette 174 is rectangular (i.e., two sides of equal length and two side of equal length but of a different length than the other two sides; or four sides of equal length) and has four corners or outer end points 201a, 201b, 201c, 201d (called out in
The first chain sprocket 188a, the first forming roller 110a, the second chain sprocket 188b, and the second forming roller 110b of the cassette 174 are accessible from the exterior 140 of the turret assembly 104 without dismantling of the turret assembly 104 while the respective cassette 174 of forming rollers 110 is physically mounted to the turret assembly 104.
Each of the first and the second blocks 184a, 184b, respectively, of each cassette 174 of forming rollers 110 are slideably mounted in the cassette frame 180 of the respective cassette 174 of forming rollers 110 to translate along an axis 210 (
Each cassette 174 of forming rollers 110 comprises at least one adjustment mechanism operable to selectively adjust a positioned of the first and the second blocks 184a, 184b of the cassette 174 of forming rollers 110 along the axis 210 that extends between the respective first and second forming rollers 110a, 110b of the respective cassette 174 of forming rollers 110. In the illustrated implementation, the at least one adjustment mechanism includes two distinct adjustment mechanisms, one operable to selectively adjust a positioned of the first block 184a in the frame 182 of the cassette 174 and one operable to selectively adjust a positioned of the second block 184b in the frame 182 of the cassette 174. In the illustrated implementation, each of the two distinct adjustment mechanisms respectively include an elongated threaded member (e.g., screw, bolt) 214a, 214b received though an aperture (e.g., threaded aperture) in a portion of the frame 182 with an inner end that physically engages (e.g., bears on) a portion of the respective one of the sliding blocks 184a, 184b, and a threaded fastener 216a, 216b (e.g., nut, lock nut), which are operable to selectively adjust the positioned of the first block 184a and the second block 184b, respectively, of the cassette 174 of forming rollers 110 along the axis 210 that extends between the respective first and second forming rollers 110a, 110b of the cassette 174 of forming rollers 110. Such may advantageously allow a spacing between the forming rollers 110 of each pair 108 to be manually adjusted as desired for a particular roll forming operation. Such may also advantageously allow the position (e.g., elevation) of the pair 108 of forming rollers 110 to be adjusted with respect to the location of the input feed 116a and/or output feed 116b and/or with respect to successive pairs 108 of forming rollers 110 in a set 106.
Preferably, the first forming roller 110a, the first chain sprocket 188a, the second forming roller 110b, and the second chain sprocket 188b of the cassette 174 are accessible from the exterior 140 of the turret assembly 104, for example with at most removal of a chain guard 150 and without dismantling of the turret assembly 104 to allow easy mounting to and dismounting from (e.g., changeover or replacement) of cassettes 174 of forming rollers 110 the turret assembly 104.
A method of operation of a roll forming machine 100 is described below, according to at least one illustrated implementation. It is noted that in operation one or more acts may be omitted, one or more acts added, and/or one or more acts performed in a different order that the order set out below.
Based on a desired cross-sectional profile of a workpiece, a first set 106 of pairs 108 of forming rollers 110 are selected. Assuming that the first set 106 of pairs 108 of forming rollers 110 are already mounted on a turret assembly 104, the turret assembly 104 is rotated, for example, to align the first set 106 of pairs 108 of forming rollers 110 with at least one of a location of an input feed 116a from which material will be feed and/or a location of an output feed 116b to which roll formed material will be deposited.
At least a portion of a transmission 114 is coupled to the first set 106 of pairs 108 of forming rollers without dissembling the turret assembly 104. For example, a forming roller drive chain 142 may be manually coupled to chain sprocket 188a, 188b that drive the forming rollers 110 of the first set 106 of forming rollers 110. Such may include removing a chain guard 150 if present in order to couple the transmission 114 with the first set 106 of pairs 108 of forming rollers 110, and subsequent placement of the chain guard 150 once the portion of the transmission 114 has been coupled to the first set 106 of pairs 108 of forming rollers 110, all without disassembling or dismantling of the turret assembly 104.
The workpiece (e.g., stock material) is feed to the first set 106 of pairs 108 of forming rollers 110 while the first set 106 of pairs 108 of forming rollers 110 are driven via the transmission 114 (e.g., forming roller drive chain 142, transfer shafts 144a, 144b, main drive chain 146, gear reducer 148) to produce a first cross-sectional profile in the workpiece.
Based on a desired cross-sectional profile of a second workpiece or further rolling forming on the previously roll formed workpiece, a second set of pairs 108 of forming rollers 110 are selected. Assuming that the second set of pairs 108 of forming rollers 110 are already mounted on a turret assembly 104, at least a portion of the transmission 114 (e.g., forming roller drive chain 142) is decoupled from the first set 106 of pairs 108 of forming rollers 110 without dissembling the turret assembly 104, and the turret assembly 104 is rotated to align a second set of pairs 108 of forming rollers 110 with at least one of the location of the input feed 116a and/or the location of the output feed 116b. Decoupling the portion of transmission 114 (e.g., forming roller drive chain 142) from the first set 106 of pairs 108 of forming rollers 110 may include removing a chain guard 150 if present, but does not employ disassembling or dismantling of the turret assembly 104.
At least a portion of the transmission 114 (e.g., forming roller drive chain 142) is coupled to the second set of pairs 108 of forming rollers 110 without dissembling the turret assembly 104. Subsequently the chain guard 150 may be reattached once the portion of the transmission 114 has been coupled to the second set of pairs 108 of forming rollers 110, all without disassembling or dismantling of the turret assembly 104.
The workpiece (e.g., stock material) is feed to the second set 106 of pairs 108 of forming rollers 110 while the second set of pairs 108 of forming rollers 110 are driven via the transmission 114 (e.g., forming roller drive chain 142, transfer shafts 144a, 144b, main drive chain 146, gear reducer 148) to produce a second cross-sectional profile.
In some instances, the sets 106 of pairs 108 forming rollers 110 on a turret assembly 104 may not include the one or more pairs of forming rollers 110 to achieve a desired cross-sectional profile, or one or more of the forming rollers 110 may be worn, or other components (e.g., chain sprockets 188a, 188b, forming roller shafts 186a, 186b, bearings 190a, 190b, 190c, 190d) may be worn or otherwise require servicing.
In such instances, one or more sets 106 of pairs 108 forming rollers 110 on the turret assembly 104 may be replaced. For example, one or more pairs 108 of existing forming rollers 110 of one set 106 on the turret assembly 104 may be detached, for example by removal of one or more fasteners (e.g., bolts, nuts, screws, clamps) and subsequent detachment or removal of a cassette 174. Then one or more pairs 108 of replacement forming rollers 110 may attached in respective positions in the one set 106 on the turret assembly 104, for example by placement of a replacement cassette 174 and securing the replacement cassette 174 to the turret assembly 104 at the desired position via one or more fasteners (e.g., bolts, nuts, screws, clamps). At least a portion of the transmission 114 (e.g., forming roller drive chain 142) may be physically coupled (e.g., mounted) to respective chain sprockets 188a, 188b of the plurality of cassettes 174 of forming rollers 110 physically coupled to the turret assembly 104 without dissembling the turret assembly 104. Replacement may employ removal of chain guard 150, but can advantageously be achieved with disassembling the turret assembly 104.
The roll forming machine installation 1000 may include one or more frames 1002a, 1002b, 1002c (three illustrated). The roll forming machine installation 1000 may include a first turret assembly 1004a rotatably mounted to the one or more frames 1002a between a location of an input feed and a location of an output feed. The roll forming machine installation 1000 may include a second turret assembly 1004b rotatably mounted to the one or more frames 1002b and located downstream of the first turret assembly 1004a (i.e., relatively closer to the location of the output feed as compared to the position of the first turret assembly 1004a). The roll forming machine installation 1000 may include a third turret assembly 1004c rotatably mounted to the one or more frames 1002c and located downstream of the second turret assembly 1004b (i.e., relatively closer to the location of the output feed as compared to the position of the second turret assembly 1004b). While not illustrated, the roll forming machine installation may include a fourth turret assembly, or even more turret assemblies, for example located successively downstream of one another.
The roll forming machine installation 1000 advantageously allows selection from a large number of roll forming operations to be performed employing minimal changeover and lost time.
While not illustrated, a roll forming machine installation may include a plurality of turret assemblies mounted to a carousel turret assembly. Such a roll forming machine installation may include a frame and a carousel turret assembly mounted to the frame. The carousel turret assembly has a carousel turret rotational axis about which the carousel turret assembly rotates with respect to the frame.
The roll forming machine installation may include a first turret assembly, a second turret assembly, and possibly a third, a fourth and even more turret assemblies. The first, second, third, fourth or even more turret assemblies are each mounted to rotate with the carousel turret assembly about the carousel turret rotational axis. The first, second, third, fourth or even more turret assemblies are each mounted to rotate about respective rotational axes of the first, second, third, fourth or even more turret assemblies, the respective rotational axes of the first, second, third, fourth or even more turret assemblies which themselves rotate about the carousel turret rotational axis of the carousel turret assembly. Rotation of the carousel turret assembly allows any one of the first, the second, the third, the forth or more turret assemblies to be selected, and rotation about a respective one of the first, the second, the third, the fourth or more turret axes allows any one of a plurality of sets of one or more pairs of forming rollers of the selected one of the first, the second, the third, the fourth or more turret assemblies to be aligned with a location of an input feed and/or a location of an output feed of the roll forming machine installation.
The roll forming machine 1100 includes a carousel frame 1102 and a carousel turret assembly 1104 rotatably mounted to the carousel frame 1102.
