Referring to
The first frame 102 also includes an actuator mount 116 opposite the crimp ring 106. The actuator mount 116 is coupled to the crimp ring 106 via a plurality of axially extending side straps 118. A bore 120 is defined within the actuator mount 116 and is adapted to receive and support an actuator 122, for example, via a threaded mounting collar 124.
The press apparatus 100 also includes a press assembly 126 coupled to the first frame 102 and disposed at least partially therein. The press assembly 126 includes the actuator 122, an actuator adjustment assembly 128, and a second frame 130. One example of the second frame 130 may be a pusher formed as a casting or a machined piece. The actuator 122 includes a driven component 132 that reciprocates linearly 133 along the actuation axis 104, which extends between the actuator mount 116 and the crimp ring 106, between an extended position and a retracted position. The driven component 132 includes a first end 134 that is at least partially disposed within the actuator 122 and a second end 136 opposite the first end 134 and positioned between the actuator mount 116 and the crimp ring 106. The driven component second end 136 is coupled to a first end 138 of the second frame 130 via at least one pin 140. The second frame 130 also includes a second end 142 opposite the first end 138 that defines a mounting location for die assembly 300. In the exemplary embodiment, the actuator 122 and driven component 132 may be a cylinder and a piston that is driven by, for example, but not limited to, a hand pump, an air/hydraulic power unit, a hydraulic power source, or an electric power source. In alternative embodiments, the actuator 122 and driven component 132 may be any other linear movement assembly that enables the press apparatus 100 to function as described herein.
The actuator adjustment assembly 128 includes a barrel 144, an adjustable knob or dial 146, and a pinch point hat 148. The barrel 144 is an annular cylinder that is rotatably coupled around the driven component 132. For example, the barrel 144 is rotatably coupled to the driven component 132 via a ball nose spring plunger (not shown). The barrel 144 is positioned on the driven component 132 such that the barrel 144 is restricted from axial movement along the actuation axis 104, but is rotatable about the actuation axis 104. The adjustable dial 146 is an annular cylinder with an annular frustoconical nose that is rotatably coupled around the driven component 132 and the barrel 144. For example, the dial 146 is threaded to the driven component 132 and surrounds the barrel 144. The dial 146 is positioned on the driven component 132 such that the dial 146 may axially move along the actuation axis 104. The dial 146 is also rotatable about the actuation axis 104 in relation to both the driven component 132 and the barrel 144. The pinch point hat 148 is an annular cylinder with flanges extending from one end. The pinch point hat 148 is coupled to the first end 138 of the second frame 130 and receives at least part of the driven component 132 and adjustable dial 146 therethrough. The driven component 132 may move axially and the adjustable dial 146 may move axially and rotationally in relation to the pinch point hat 148.
In operation, to join the fitting assembly 202 to the hose 204, the die assembly 300 is coupled to the second frame 130. The actuator adjustment assembly 128 is adjusted for the hose size and type to define an extension length of the driven component 132 along the actuation axis 104 towards the crimp ring 106. The fitting assembly 202 and the hose 204 are positioned within the crimp ring 106. The driven component 132 may be actuated by the actuator 122 to move from a retracted position (shown in
The second end 136 of the driven component 132 includes a threaded section 154 and a pair of openings 156 defined therethrough. The threaded section 154 extends for a length along the actuation axis 104 and receives corresponding threads of the adjustable dial 146. The openings 156 extend for a length along the actuation axis 104 and receives pin 140 (shown in
The central opening 176 also includes a second opening section 184 disposed as a second end 186 of the body 174. An inner circumferential surface 188 of the body 174 at the second opening 184 includes threads 190 such that the adjustable dial 146 is threaded onto and coupled to the threaded section 154 of the driven component 132. As such, the adjustable dial 146 is rotatable with respect to the driven component 132 and is moveable axially with respect to the driven component 132 along the actuation axis 104.
To join the fitting assembly 202 to the hose 204, a first end 214 of the hose 204 may be inserted around the nipple 210 and within the socket 212. The press apparatus 100 may then be utilized to crimp the fitting assembly 202 and secure the fitting assembly 202 to the hose 204 via the die assembly 300 (shown in
The dies 304 are circumferentially spaced about the longitudinal axis 104 between the first and second plates 306, 308. The dies 304 are adapted to selectively reciprocate in the die cage 302 between a retracted position and a crimp position. In the retracted position, the first radial ends 314 of the dies 304 extend into the central opening 310 of the first and second plates 306, 308, while the second radial ends 316 extend beyond an outer diameter of each of the first and second plates 306, 308. In the retracted position, the dies 304 define a center opening 322 that is adapted to receive the socket 212 of the hose assembly 200 (shown in
In the crimp position, the first radial ends 314 of the dies 304 move radially inward into the central opening 310 of the first and second plates 306, 308. In the crimp position, the center opening 322 defined by the dies 304 has a circumference that is smaller than the circumference of the center opening 322 in the retracted position. In the exemplary embodiment, actuation of the die assembly 300 between the retracted position and the crimp position is induced by actual extension of the driven component 132 as discussed in further detail below.
More specifically, and referring to
The crimp die set markings 408 may be visually arranged in groups according to hose type 410. For example, the crimp die set markings 408 illustrated in
Once the required die assembly 300 is coupled to the second frame 130, the press assembly 126 may be adjusted to accommodate the hose type (GH493-16), the fitting assembly (4S), and the die assembly (M420) such that a desired crimp joint is formed. The driven component 132 is linearly actuatable between a retracted position and an extended crimping position along the actuation axis 104. The further the second end 136 axially extends toward the crimp ring 106 the further the dies 304 are radially displaced in the crimp position forming the crimp. If the dies 304 are not displaced enough, the fitting assembly 202 may be under-crimped and if the dies 304 are displaced too much, the fitting assembly 202 may be over-crimped, both of which are undesirable for the joint. Additionally, the axial depth of the die assembly 300 may vary and will need to be accounted for. As such, the actuator adjustment assembly 128 may be used to adjust the extension length of the second end 136 while in the extended position.
To set the actuator adjustment assembly 128, the barrel 144 is selectively rotated about the driven component 132 until the hose type 410 is positioned at a front side of the press apparatus 100. In the exemplary embodiment, the barrel 144 is divided into four radial sections on the outer circumferential surface 172 and each corresponding to the hose type 410, such as GH493 (
Once the barrel 144 is selectively rotated into a position that corresponds to the desired hose type 410, the adjustable dial 146 may be selectively rotated about the actuation axis 104 to adjust the axial extension length of the driven component 132 for use. The adjustable dial 146 includes a plurality of circumferentially spaced-apart hose size markings 416 sets positioned on the oblique section 182. Each set of circumferentially spaced-apart hose size marking 416 corresponds to the hose type 410 and are coded to correspond to the die assembly 300 that may be used. Similar to the crimp die set markings 408, each set of the circumferentially spaced-apart hose size markings 416 may be color coded (white, green, and orange) to match the hose type 410 set forth in the crimp die set markings 408 and the barrel 144 to facilitate ease of use. Additionally, the adjustable dial 146 may include a set of generic circumferentially spaced-apart hose size markings 418 (shown in
To set the actuator adjustment assembly 128 for using the press apparatus 100, the hose size in each of the axially spaced-apart hose size markings 412 on the barrel 144 is selectively matched in a cross-hair arrangement to a corresponding circumferentially spaced-apart hose size marking 416 on the adjustable dial 146, for the known hose type 410. For example, a hose type GH493-16 is positioned at 400 (
Once the press apparatus 100 is set for use, the hose assembly 200 may be inserted within the central bore 112 of the crimp ring 106. The press assembly 126 may be actuated such that the driven component 132 is actuated by the actuator 122 and axially moves towards the crimp ring 106. As the driven component 132 is actuated, the center opening 322 of the die assembly 300 receives the hose assembly 200 and the dies 304 are radially displaced by slidingly engaging with the central bore inner surface 114 to crimp the fitting assembly 202 to the hose 204 and join the two components. This process may be repeated and the actuator adjustment assembly 128 adjusted for varying hose types.
As the driven component 132 is moved to the retracted position, the second frame 130 slides, via the elongated openings 156, towards the second end 136. This movement enables the actuator adjustment assembly 128 to be rotatable about the driven component 132 and the extension length to be set. Once the actuator adjustment assembly 128 is set and the driven component 132 is moved into the extension position, the second frame 130 may slide within the openings 156 towards the first end 134 until pressure can be applied via the actuator 122 to facilitate the crimping process. The driven component 132 continues to be moved into the extension position until stopped by the adjustable dial 146 position.
The actuation adjustment assembly described herein enables the press apparatus to be used for a plurality of hose types and diameters without the need to reference additional manuals or reference sources. As such, the embodiments described herein provide an economical and efficient press apparatus. Additionally, the actuation adjustment assembly includes two main moving parts thereby increasing durability and ease of use in the field.
Various modification and alterations of this disclosure will become apparent to those skilled in the art without departing from the scope and spirit of this disclosure, and it should be understood that the scope of this disclosure is not to be unduly limited to the illustrative embodiments set forth herein.
The present application claims the benefit of priority to U.S. Provisional Patent No. 62/453,364, titled “ADJUSTMENT ASSEMBLY FOR A PRESS APPARATUS,” and filed on Feb. 1, 2017, the disclosure of which is hereby incorporated by reference in its entirety.
