Abstract
Description
Technical Field
[0001] This utility model relates to the field of support roller manufacturing technology, and in particular to an auxiliary demolding device for support roller stamping production. Background Technology
[0002] Track rollers hold the track links with their roller flanges, distributing the machine's weight across the track pads while limiting lateral slippage of the tracks, ensuring the machine moves along the track direction. Track rollers have low rolling resistance, making them suitable for operation in mud and water, and have a long service life.
[0003] During the production of track rollers, the material needs to be heated after being cut and produced by forging. During forging, the internal cavity size of the mold is fixed. In some cases, the forging expands and sticks together, making it impossible to remove it quickly from the forging mold. Therefore, a demolding structure that facilitates material removal is required. Utility Model Content
[0004] This utility model addresses the deficiencies in the prior art by providing an auxiliary demolding device for the production of support rollers in stamping.
[0005] This utility model is achieved through the following technical solution:
[0006] An auxiliary demolding device for stamping support rollers includes a forging die, an insert assembly, a support roller, a screw, a limiting block, and an ejection mechanism. The insert assembly is engaged inside the top of the forging die, the support roller is engaged inside the insert assembly, the screw is threaded to the forging die, the limiting block is movably connected to the end of the screw, and the ejection mechanism is engaged at both ends of the top of the forging die. The insert assembly includes an inner nest, a positioning rod, a cover plate, a retaining shaft, and a spring. The positioning rod is fixedly disposed at the bottom of the inner nest, the retaining shaft is engaged at the top of the inner nest, the cover plate is fixed to the top of the retaining shaft, and the spring is sleeved outside the retaining shaft.
[0007] In a preferred embodiment of the present invention, the ejection mechanism includes an insert plate, a connecting rod, and a rocker plate. The insert plate is snapped onto the top of both ends of the inlay assembly, and an installation groove is provided on the top of the insert plate. The connecting rod is fixedly disposed in the installation groove on the top of the insert plate, and the rocker plate is movably connected to the connecting rod.
[0008] The ejection mechanism mainly lifts the cover plate at the top of the inner nest, thereby providing an upward lifting force to the bottom of the forging, which facilitates the loosening and demolding of the forging.
[0009] In a preferred embodiment of the present invention, the top of the rocker is inclined downward, and the top of the inner nest is provided with a groove that cooperates with the rocker. One end of the top of the rocker is locked to the bottom of the cover plate.
[0010] The top of one end of the rocker is tilted downwards to facilitate locking the bottom of the cover plate. As the rocker is pushed forward, the cover plate will automatically rise due to the influence of its top slope, making it easier to remove the part.
[0011] In a preferred embodiment of the present invention, the limiting block is fitted inside the forging mold, with one end fitted to the outer side of the inner nest, and a groove is provided on the outer side of the inner nest to cooperate with the limiting block.
[0012] The limiting block is mainly used to effectively fix the inner nest. When the inner forging cannot be removed, the restriction of the limiting block can be released to remove the inner nest and the forging together, thus facilitating the separation of the two.
[0013] In a preferred embodiment of this utility model, the bottom inner side of the forging mold is provided with a positioning hole that cooperates with the positioning rod, and the two ends of the inner nest are provided with limit plates.
[0014] The beneficial effects of this utility model are:
[0015] This auxiliary demolding device for support roller stamping production can effectively impact the bottom of the support roller and provide an upward ejection force when the support roller cannot be quickly removed from the mold after stamping and forging. This allows the support roller stamping to be smoothly separated from the mold and lifts the support roller to a certain height for easy removal of the finished product. The inner nest is detachable, and in extreme cases, quick disassembly of the inner nest can achieve smooth demolding of the forging. Attached Figure Description

[0021] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings, so that the advantages and features of this utility model can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of this utility model. The directional terms mentioned in this utility model, such as "up," "down," "front," "back," "left," "right," "top," and "bottom," are only for reference to the accompanying drawings. Therefore, the directional terms used are for the purpose of explaining and understanding this utility model, and not for limiting this utility model.
[0022] like Figure 1-4 The auxiliary demolding device for stamping production of support rollers shown includes a forging die 1, an insert assembly 2, a support roller 3, a screw 4, a limiting block 5, and an ejection mechanism 6. The insert assembly 2 is locked inside the top of the forging die 1, the support roller 3 is locked inside the insert assembly 2, the screw 4 is threadedly connected to the forging die 1, the limiting block 5 is movably connected to the end of the screw 4, and the ejection mechanism 6 is locked at both ends of the top of the forging die 1. The insert assembly 2 includes an inner nest 21, a positioning rod 22, a cover plate 23, a retaining shaft 24, and a spring 25. The positioning rod 22 is fixedly set at the bottom of the inner nest 21, the retaining shaft 24 is locked at the top of the inner nest 21, the cover plate 23 is fixed to the top of the retaining shaft 24, and the spring 25 is sleeved on the outside of the retaining shaft 24.
[0023] Specifically, the ejection mechanism 6 includes an insert plate 61, a connecting rod 62, and a rocker plate 63. The insert plate 61 is engaged at the top of both ends of the inlay assembly 2. The top of the insert plate 61 has an installation groove. The connecting rod 62 is fixedly installed in the installation groove at the top of the insert plate 61. The rocker plate 63 is movably connected to the connecting rod 62. The top of the rocker plate 63 is inclined downward. The top of the inner nest 21 has a slot that cooperates with the rocker plate 63. One end of the top of the rocker plate 63 is engaged at the bottom of the cover plate 23. The limiting block 5 is engaged inside the forging mold 1, and one end of it is engaged to the outside of the inner nest 21. The outside of the inner nest 21 has a slot that cooperates with the limiting block 5. The bottom inner side of the forging mold 1 has a positioning hole that cooperates with the positioning rod 22. The inner nest 21 has limiting plates at both ends.
[0024] In this embodiment, the inner nest 21 is fitted into the mounting groove at the top of the forging mold 1, the positioning rod 22 is inserted into the positioning hole at the bottom of the forging mold 1, and then the screw 4 is screwed in, so that the limiting block 5 moves forward and is fitted into the outer groove of the inner nest 21 at its end. Then the forging process is performed. After the stamping equipment performs the forging process, the forged support roller 3 will remain in the inner nest 21.
[0025] Furthermore, to facilitate the removal of the support roller 3, simply tap the end of the insert plate 61 inward to move the insert plate 61 forward, thereby pushing the rocker plate 63, which is locked at the bottom of the cover plate 23, forward. Since the top of the rocker plate 63 is inclined, the forward rocker plate 63 will push the cover plate 23 upward, thereby exerting an upward force on the bottom of the top edge of the support roller 3, causing the support roller 3 to loosen. Further, press the end of the rocker plate 63 to rotate the rocker plate 63 around the connecting rod 62, further lifting the inclined end of the top of the rocker plate 63, so that the support roller 3 is pried up and completely separated from the inner nest 21, maintaining a certain height to facilitate the smooth removal of the support roller 3. Then, pull the insert plate 61 back, and under the action of the spring 25, the cover plate 23 will automatically reset. In extreme cases, if the support roller 3 cannot be separated from the inner nest 21, simply rotate the screw 4 to separate the limiting block 5 from the inner nest 21, and the inner nest 21 and the forging can be removed at the same time. The split inner nest 21 can be quickly separated from the forging.
