Abstract
A formed element trimming apparatus includes a base member, a nesting member connected to a ram cylinder mounted on one end of the base member, a clamping member connected to a clamping cylinder mounted to a second end of the base member, and a cutting plate attached to the base member between the nesting member and the clamping member. The cutting plate has a cutting aperture to engage any undesired attachments on the periphery of the formed element. The formed element is securely placed in the nesting member, which is designed to integrally receive the formed element. The clamping member, propelled by the clamping cylinder, traverses the cutting aperture to engage the nesting member and secure the position of the formed element between the nesting member and the clamping member. The ram cylinder is then activated to overpower the clamping cylinder and force the nesting member and clamping member back through cutting aperture such that the any undesired attachments on the periphery of the formed element will contact the periphery of the cutting aperture to truncate such undesired attachments from the formed element. The apparatus may further include an auxiliary apparatus to trim the formed element in a second dimension.
Description




FIELD OF THE INVENTION




The present invention relates to trimmers for formed elements, such as castings, forgings, and similar elements, and, more particularly, to an apparatus and method for efficiently trimming burrs, fins, parting lines, and other undesired attachments from the surface of a formed element, such as a casting, forging, or similar element.




BACKGROUND OF THE INVENTION




A common problem occurring with the production of formed elements is that undesired rough edges, such as burrs, and other undesired attachments, such as fins or parting lines, frequently remain on the formed element after the formed element has been cast, forged, or formed, and subsequently cut. The rough edges and undesired attachments can cause problems when the formed element is ready to be installed in the intended apparatus in that the imperfect formed element may prevent the apparatus from operating as required. As a result, it is necessary that each burr, fin, parting line, or other undesired attachment be removed from the formed element before the formed element is to be used.




Several trimmer designs have been developed in an attempt to easily remove such undesired attachments on the surface of the formed element. A conventional way to trim a formed element is done via a four post press or a similar ā€œCā€ frame press. These conventional presses generally consist of a cutter die and a nest to contain the formed element. The formed element is loaded directly into the nest either by hand, a shuttle car, or a turn table, and the cutter die strokes down. The burr is then stripped off, and then the cycle is repeated by retracting the cutter die from around the formed element. A problem with such designs is that the cutter die experiences significant amounts of wear and is not capable of easily being sharpened. Additionally, the formed element is also not discharged automatically, and therefore must be removed by hand or by a specially designed means.




A series of patents describe different devices that are used to remove burrs from castings. For example, in U.S. Pat. No. 5,343,929 to Landua, et al., an apparatus is described for deburring foundry cores. This design provides a press to remove burrs from the foundry core. However, such a device is unable to engage the total periphery of the core to remove bores. The design includes an elastic gripping member to hold and support the core, which prevents the press from completely engaging the outer periphery of the core. Furthermore, this device requires a vibrating means to remove the burrs, which makes it more complicated to design and maintain. As a result, such a design is more complex and does not function to exhaustively deburr the core.




What is needed, then, and not found in the prior art, is an apparatus and method for efficiently removing any undesired attachments present on a formed element such that the entire periphery of the formed element is trimmed and cleaned, and including a cutting plate that is easily sharpened or replaced as necessary for various formed elements.




SUMMARY OF THE INVENTION




An object of the present invention is to provide an apparatus for removing undesired attachments from a formed element.




A further object of the present invention is to provide an apparatus for removing undesired attachments from a formed element with an easily replaceable cutting plate.




A further object of the present invention is to provide an apparatus able to remove undesired attachments from multiple shapes of formed elements.




A further object of the present invention is to provide an apparatus for removing undesired attachments from multiple surfaces of a formed element.




A further object of the present invention is to provide an apparatus for removing undesired attachments from a formed element such that the formed element is held securely to prevent rotation of the formed element while traversing a cutting aperture.




These and other objects of the invention are accomplished through the present apparatus and method for trimming formed elements. This apparatus includes a nesting member for receiving a formed element attached to a ram cylinder and a clamping member attached to a clamping cylinder. Positioned between the nesting member and the clamping member is a cutting plate having a cutting aperture that is designed to engage any undesired attachments connected to the formed element. A formed element to be trimmed may be placed in the nesting member, and the clamping member may then be extended linearly though the cutting aperture to engage the formed element resting in the nesting member. The ram cylinder then extends to overpower the clamp cylinder and push the nesting member and the clamping member through the cutting aperture. The cutting aperture is designed such that the undesired attachments connected to the formed element will be trimmed upon passing through the cutting aperture. The clamping cylinder exerts a stabilizing force to prevent the formed element from rolling or twisting while the formed element traverses the cutting aperture. Once the nesting member has passed through the cutting aperture, the clamping member retracts, which allows the trimmed formed element to fall or be extracted.

such that the elements are able to interact with each other and thereby remove any undesired attachments


26


, such as ingates, burrs, fins, or parting lines, from the periphery of the surface of a formed element


12


(see FIGS.


7


A and


7


B).




Looking at

FIGS. 1A

,


1


B,


2


, and


3


, the formed element receiving means


16


is designed to secure the position of the formed element


12


before the formed element


12


is trimmed. The formed element receiving means


16


includes a nesting member


28


, a ram cylinder


30


, a ram cylinder rod


31


, and a nesting positioning plate


29


. The first brace


33


of the frame


32


supports the ram cylinder


30


, which is a conventional hydraulic cylinder. The ram cylinder rod


31


acts as a conventional piston rod used by the ram cylinder


30


, such that the ram cylinder rod


31


is able to be linearly extended and retracted by the ram cylinder


30


.




The nesting member


28


is attached to a cantilevered end of the ram cylinder rod


31


, and the nesting member


28


is designed to securely and integrally grip the formed element


12


. As a result, the ram cylinder


30


will provide linear movement of the ram cylinder rod


31


to extend and retract the nesting member


28


holding the formed element


12


. Additionally, the nesting positioning plate


29


is slidably mounted on the guide rods


35


and serves as a support member for the ram cylinder rod


31


such that the ram cylinder rod


31


does not vary from its desired path.




The apparatus


10


for trimming formed elements


12


further includes a clamping means


18


that is used to contact the formed element


12


positioned on the nesting member


28


to secure the position of the formed element


12


on the nesting member


28


. The clamping means


18


includes a clamping member


36


, a clamping cylinder


34


, a clamping cylinder rod


40


, and a clamping positioning plate


39


. The second brace


38


of the frame


32


supports the clamping cylinder


34


, which is a conventional hydraulic cylinder. The clamping cylinder rod


40


acts as a conventional piston rod used by the clamping cylinder


34


, such that the clamping cylinder rod


40


is able to be linearly extended and retracted by the clamping cylinder


34


. The clamping member


36


is attached to a cantilevered end of the clamping cylinder rod


40


, and the clamping member


36


is designed to securely and integrally engage the formed element


12


and nesting member


28


. As a result, the clamping cylinder


34


will provide linear movement of the clamping cylinder rod


40


to extend and retract the clamping member


36


. Additionally, the clamping positioning plate


39


is slidably mounted on the guide rods


35


and serves as a support member for the clamping cylinder rod


40


such that the clamping cylinder rod


40


does not vary from its desired path.




Looking further at

FIGS. 1A

,


1


B,


2


and


3


, the cutting means


20


is also attached to the table member


22


by a third brace


41


of the frame


32


. In the preferred embodiment, the cutting means


20


includes a backing structure


42


that is removeably attached to the third brace


41


, and at least one cutting plate


44


that is in turn removeably attached to the backing structure


42


. The cutting plate


44


and the backing structure


42


are thereby positioned on the third brace


41


in proximate relation to each other. Both the cutting plate


44


and the backing structure


42


include a cutting aperture


46


designed to sever any undesired attachments


26


from the periphery of the formed element


12


. The cutting plate


44


may be mounted to the third brace


41


without the backing structure


42


, but the backing structure


41


provides support for the cutting plate


44


in trimming formed elements


12


.




The process of trimming undesired attachments


26


from the periphery of the formed element


12


is illustrated in

FIGS. 4 through 6

. Looking at

FIG. 4

, the process begins with the formed element


12


being positioned with respect to the nesting member


28


of the formed element receiving means


16


. Referring to

FIG. 5

, the clamping cylinder


34


then extends the clamping rod


40


toward the cutting means


20


such that the clamping member


36


traverses the cutting aperture


46


in the cutting plate


44


and backing structure


42


. The clamping member


36


thereby comes into contact with the formed element


12


and applies a force to secure the formed element


12


between the nesting member


28


and the clamping member


36


, such that the clamping member


36


and the nesting member


28


act as a vice to securely hold the formed element


12


, as shown in FIG.


8


.




The ram cylinder


30


then effectuates a force such that the ram cylinder rod


31


extends outward from the ram cylinder


30


. The force of the ram cylinder


30


overpowers the force applied by the clamping cylinder


34


, and thereby forces the clamping cylinder


34


, the nesting member


28


and the secured formed element


12


toward the cutting means


20


, as shown in FIG.


6


. The nesting member


28


and the clamping member


36


are designed to traverse the cutting aperture


46


without making contact with the cutting aperture


46


. Although the nesting member


28


and the clamping member


36


are able to traverse the cutting aperture


46


, the periphery of the cutting aperture


46


is designed to be substantially similar in size and shape as the periphery of the formed element


12


, or the cutting aperture is designed to be substantially similar to one side of the formed element


12


, such that an undesired attachment


26


positioned on the periphery of the formed element


12


will be truncated from the formed element


12


. As a result, as the ram cylinder


30


forces the clamping member


36


, nesting member


28


, and formed element


12


through the cutting aperture


46


, only the undesired attachments


26


will make contact with the cutting plates


44


to remove the undesired attachments


26


. Furthermore, since the clamping member


36


acts as a vice in conjunction with the nesting member


28


, the formed element


12


is unable to roll or twist out of the secured position.




Once the formed element


12


has passed through the cutting aperture


46


, the formed element


12


may be removed from the secured position between the nesting member


28


and the clamping member


36


. After guiding the formed element


12


through the cutting plate


44


, the clamping member


36


may be retracted such that the formed element


12


may fall away from the nesting member


28


, or the formed element


12


may be extracted, such as with a robotic hand and arm (not shown) that may be maneuvered to engage and remove the formed element


12


.




Looking at

FIGS. 9A-9C

, a series of cutting plates


44




a


,


44




b


, and


44




c


are illustrated having various outlines of cutting apertures


46




a


,


46




b


, and


46




c


. The cutting apertures


46




a


,


46




b


, and


46




c


illustrated in

FIGS. 9A-9C

are each designed with a specific cutting edge


45


to engage a specific portion of the formed element


12


sequentially, as shown in FIG.


10


. As illustrated in

FIGS. 9A-9C

, the cutting apertures


46




a


,


46




b


, and


46




c


within the cutting plates


44




a


,


44




b


, and


44




c


may be varied according to the type of formed element


12


that is to be trimmed and the shape associated with that formed element


12


, or the cutting apertures


46




a


,


46




b


, and


46




c


may be varied to have cutting edges


45


to engage the specific individual surfaces of the formed element


12


that are to be trimmed. Each cutting aperture


46




a


,


46




b


, and


46




c


is designed such that the clamping member


36


and the nesting member


28


will be able to traverse the cutting aperture


46




a


,


46




b


, and


46




c


without contacting the periphery of the cutting aperture


46




a


,


46




b


, and


46




c


while the desired surface or surfaces of the formed element


12


will engage the piercing edge of the cutting aperture


46




a


,


46




b


, and


46




c


such that the contact will trim and remove the undesired attachment


26


from the formed element


12


. As a result, it is clear that the shape of the cutting member


36


and nesting member


28


may be varied also according to the formed element


12


that is to be trimmed.




Looking at

FIG. 11

, the cutting means


20


may include multiple cutting plates


44




a


,


44




b


, and


44




c


attached to the backing structure


42


either rigidly or loosely Each individual cutting plate


44




a


,


44




b


, and


44




c


may include a cutting aperture


46




a


,


46




b


, and


46




c


having a varied design (as shown in

FIGS. 9A-9C

) such that each cutting aperture


46




a


,


46




b


, and


46




c


will engage a different surface of the formed element


12


. Therefore, by including multiple cutting plates


44




a


,


44




b


, and


44




c


, the user is able to engage the desired surface at separate times to avoid overstressing the cutting means


20


and aligning the cutting plates


44




a


,


44




b


, and


44




c


according to the variations of the formed element


12


at one time. Moreover, using multiple cutting plates


44




a


,


44




b


, and


44




c


allows the user to easily alter the cutting means


20


should the user not desire to engage one surface of the formed element


12


or should the shape of the formed element


12


be varied.




One advantage of the present invention is the easy substitution of one cutting plate


44


with another cutting plate


44


when the periphery of the cutting aperture


46


is dulled. Since each cutting plate


44


is removeably mounted to the backing structure


42


and frame


32


, it may be replaced when the periphery of the cutting aperture


46


is not as sharp as desired. In the preferred embodiment, the mounted connection is made by bolts that engage the backing structure


42


when the cutting plate


44


gets dull, the bolts holding the cutting plate


44


may be removed, and the face of the cutting plate


44


may be sharpened. Furthermore, this apparatus


10


for trimming formed elements


12


is easily adaptable to a plurality of types of formed elements


12


that must be trimmed and cleaned before they can be used.




A second embodiment of the apparatus


10


for trimming formed elements


12


is illustrated in FIG.


12


. In this embodiment, the apparatus


10


for trimming formed elements


12


may be designed to trim undesired attachments


26


from the formed elements


12


in two dimensions as opposed to one dimension as described in the first embodiment above. In such an embodiment, the apparatus


10


for trimming formed elements


12


, in addition to the embodiment described above, further includes an auxiliary cutting means


48


for trimming the undesired attachments


26


of the formed element


12


in the additional dimension. In such an embodiment, the formed element


12


is trimmed in the first dimension as described above. However, after the formed element


12


has traversed the cutting plate


44


, the formed element


12


will then be engaged by an auxiliary formed element receiving means


50


and an auxiliary clamping means


52


for additional trimming at another angle.




The auxiliary formed element receiving means


50


and the auxiliary clamping means


52


are preferably positioned substantially perpendicular with respect to the nesting member


28


and the clamping member


36


, although these formed elements are not exclusively positioned at a perpendicular angle. An auxiliary cutting plate


53


is thereby positioned between the auxiliary formed element receiving means


50


and the auxiliary clamping means


52


to engage various surfaces of the formed element


12


that were not previously engaged by the cutting means


20


.




Similar to the embodiment described above, the auxiliary formed element receiving means


50


includes a secondary nesting member


54


, a secondary ram cylinder


56


, a secondary ram cylinder rod


58


, and a secondary nesting positioning plate


60


. A reinforcement brace


62


supports the secondary ram cylinder


56


, which is a conventional hydraulic cylinder. The secondary ram cylinder rod


58


acts as a conventional piston rod used by the secondary ram cylinder


56


, such that the secondary ram cylinder rod


58


is able to be linearly extended and retracted by the secondary ram cylinder


56


.




The secondary nesting member


54


is attached to a cantilevered end of the secondary ram cylinder rod


58


, and the secondary nesting member


54


is designed to securely and integrally grip the formed element


12


. As a result, the secondary ram cylinder


56


will provide linear movement of the secondary ram cylinder rod


58


to extend and retract the secondary nesting member


54


holding the formed element


12


. Additionally, the secondary nesting positioning plate


60


is slidably mounted on secondary guide rods


64


and serves as a support member for the secondary ram cylinder rod


58


such that the secondary ram cylinder rod


58


does not vary from its desired path.




The auxiliary clamping means


52


includes a secondary clamping member


68


, a secondary clamping cylinder


70


, a secondary clamping cylinder rod


72


, and a secondary clamping positioning plate


74


. A reinforcement brace


76


supports the secondary clamping cylinder


70


, which is a conventional hydraulic cylinder. The secondary clamping cylinder rod


72


acts as a conventional piston rod used by the secondary clamping cylinder


70


, such that the secondary clamping cylinder rod


72


is able to be linearly extended and retracted by the secondary clamping cylinder


70


. The secondary clamping member


68


is attached to a cantilevered end of the secondary clamping cylinder rod


72


, and the secondary clamping member


68


is designed to securely and integrally engage the formed element


12


and secondary nesting member


54


. As a result, the secondary clamping cylinder


70


will provide linear movement of the secondary clamping cylinder rod


72


to extend and retract the secondary clamping member


68


. Additionally, the secondary clamping positioning plate


74


is slidably mounted on the secondary guide rods


64


and serves as a support member for the secondary clamping cylinder rod


72


such that the secondary clamping cylinder rod


72


does not vary from its desired path.




The secondary clamping member


68


thereby traverses the secondary cutting aperture


55


, and the secondary clamping member


68


and the secondary nesting member


54


thereby engage the formed element


12


. The secondary ram cylinder


56


then effectuates a force such that the secondary ram cylinder rod


58


extends outward from the secondary ram cylinder


56


. The force of the secondary ram cylinder


56


overpowers the force applied by the secondary clamping cylinder


70


, and thereby forces the secondary clamping cylinder


70


and the formed element


12


secured between the secondary nesting member


54


and the secondary clamping member


68


towards the secondary cutting means


48


. As with the first embodiment, the secondary nesting member


54


and the secondary clamping member


68


are designed to traverse the secondary cutting aperture


55


without making contact with the cutting aperture


55


. Although the secondary nesting member


54


and the secondary clamping member


68


are able to traverse the secondary cutting aperture


55


, the periphery of the secondary cutting aperture


55


is designed to be substantially similar in size and shape as the periphery of a second side of the formed element


12


, or the cutting aperture is designed to be substantially similar to that side of the formed element


12


, such that an undesired attachment


26


positioned on the periphery of the formed element


12


will be truncated from the formed element


12


. As a result, as the secondary ram cylinder


56


forces the secondary clamping member


68


, secondary nesting member


54


, and formed element


12


through the secondary cutting aperture


55


, only the undesired attachments


26


will make contact with the periphery of the secondary cutting apertures


55


to remove the undesired attachments


26


. Finally, the trimmed formed element


12


will be available to be extracted in the manner that the user desires.




Thus, although there have been described particular embodiments of the present invention of a new and useful APPARATUS AND METHOD FOR TRIMMING FORMED ELEMENTS, it is not intended that such references be construed as limitations upon the scope of this invention except as set forth in the following claims.
