Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of stamping equipment, in particular to a motorcycle accessory multi-station stamping forming device facilitating mold switching. BACKGROUND

[0002] In the field of motorcycle manufacturing, the forming of numerous accessories cannot be separated from the stamping process. Key accessories such as frames, hubs, and engine housings often have complex shapes, including various bending, stretching, and punching features, so they usually need to be processed through multiple stamping processes.

[0003] Specifically, due to the complexity and precision requirements of these accessory shapes, a single stamping cannot meet the requirements of complex shapes and precision, so multiple stamping is required. Multiple stamping can gradually shape the accessory, and in each stamping process, specific shape features can be processed to achieve precise control of complex shapes, ensuring the quality and performance of the accessory and meeting the strict requirements of motorcycles in terms of safety, reliability, and comfort.

[0004] Currently, for motorcycle accessories that require multiple stamping, the existing multi-station stamping method usually places a workpiece in the lower die of a stamping device, removes it from the lower die of the stamping device after completing a stamping process, and then places it in the lower die of another stamping device. This cycle is repeated to complete multiple stamping. However, the above stamping method can meet the requirements of multiple stamping, but it also has many defects. Specifically, during manual transfer, the worker's physical strength and attention are limited, and long-term repetitive operation can lead to fatigue, resulting in reduced transfer speed. Additionally, using manual transfer undoubtedly increases labor costs. Using a robot for transfer not only requires a high upfront purchase cost, but also requires ongoing maintenance costs, which small businesses may find difficult to afford. Therefore, the present application proposes a motorcycle accessory multi-station stamping forming device facilitating mold switching to solve the above problems. SUMMARY

[0029] Specifically, the clamping part 504 includes a clamping cover 5041 and a clamping piece 5042, the clamping cover 5041 is connected with the clamping rod 503, and the clamping cover 5041 is a hollow structure, the clamping piece 5042 is elastically connected to the side of the clamping cover 5041 which is away from the clamping rod 503 by a spring, as shown in Figure 6 In this way, when the clamping piece 5042 and the clamped workpiece are in contact, rigid collision will not occur, which is beneficial to protect the workpiece.

[0030] In another embodiment of the present application, the top surface of the bearing table 300 is symmetrically provided with two wiring boards 303 on the front and rear sides, the middle section of the wiring board 303 is raised towards the displacement part 400, the distance between the middle sections of the two wiring boards 303 is smaller than the distance between the two ends of the wiring board 303, and the wiring groove 304 is provided through the wiring board 303; as shown in Figure 2 the wiring board 303 is in a three-section structure, the middle section is closer to the sliding groove 301 than the left and right sections, and the wiring board 303 is made of aluminum alloy and is fixedly connected to the top surface of the bearing table 300 by bolts.

[0031] Further, the end of the clamping rod 503 opposite to the clamping part 504 is provided with a wiring column 505, the wiring column 505 penetrates the wiring groove 304, the middle section of the surface of the wiring column 505 is provided with a guide protrusion 506, and the outside of the wiring column 505 is further movably provided with a guide gasket 507, the guide gasket 507 and the outside end of the wiring column 505 are elastically connected by an elastic member 508, and the guide protrusion 506 and the guide gasket 507 are respectively attached to the inner and outer surfaces of the wiring board 303; wherein the wiring column 505 and the clamping rod 503 are fixedly connected by bolts, the guide protrusion 506 and the wiring column 505 are an integral structure, and the guide protrusion 506 is attached to the inner surface of the wiring board 303, and the guide gasket 507 is elastically connected to the outside end of the wiring column 505; in this embodiment, the elastic member 508 is a spring, and the spring is always in a compressed state, which allows the guide gasket 507 to always be attached to the outer surface of the wiring board 303.

[0032] Therefore, during the movement of the wiring column 505 along the wiring groove 304, when the wiring column 505 is located at the left and right ends of the wiring board 303, the distance between the two clamping parts 504 is the farthest, and the distance between the two clamping parts 504 is greater than the length of the workpiece to be processed; when the wiring column 505 enters the middle section of the wiring board 303, the two clamping parts 504 can be close to each other, thereby clamping the workpiece.

[0033] Further, the wiring groove 304 is in a posture of low at both ends and high in the middle, when the wiring column 505 moves to the middle section of the wiring groove 304, the two clamping parts 504 can clamp the workpiece and lift it up. Specifically, the section of the wiring groove 304 with a higher position is located on the middle section of the wiring board 303, that is, the two clamping parts 504 clamp the workpiece first and then lift it up. It is worth mentioning that the heights of the two end positions of the wiring groove 304 are consistent, and the maximum height difference of the wiring groove 304 is not less than 30 mm.

[0034] In another embodiment of the present application, the inner bottom surface of the first lower mold 402 is movably embedded with a jacking block 406, the front and rear sides and the bottom of the first lower mold 402 are collectively provided with a mounting cavity 407, the bottom of the mounting cavity 407 is provided with a bottom plate 408, and the mounting cavity 407 is provided with a lifting adjusting assembly 409 for driving the jacking block 406 to lift; when the two clamping parts 504 are close to each other, the lifting adjusting assembly 409 can drive the jacking block 406 to rise and jack up the workpiece upward.

[0035] Specifically, the lifting adjusting assembly 409 includes two movable parts 4091, which are in the shape of an L-shaped plate. The top end of the movable part 4091 extends out of the mounting cavity 407 and is exposed above the top surface of the first lower mold 402. The two movable parts 4091 are in sliding cooperation with the bottom plate 408. That is, the two movable parts 4091 can be close to or away from each other. The bottom surface of the jacking block 406 is provided with a jacking column 410, which movably penetrates into the mounting cavity 407. The jacking column 410 is hingedly connected to the two movable parts 4091 through two connecting rods 4092, respectively. When the two movable parts 4091 are close to each other, the jacking column 410 and the jacking block 406 are pushed to rise. Conversely, when the two movable parts 4091 are away from each other, the jacking column 410 and the jacking block 406 are pulled to descend.

[0036] Further, the jacking column 410 is externally sleeved with a return spring 411, the two ends of the return spring 411 are in abutment with the inner top surface of the mounting cavity 407 and the bottom end of the jacking column 410, respectively. In the natural state, the return spring 411 is in a compressed state, and the top surface of the jacking block 406 is flush with the inner bottom surface of the first lower mold 402. It is worth mentioning that the inner bottom surface of the first lower mold 402 has an embedded groove for embedding the jacking block 406. The gap between the jacking block 406 and the embedded groove is extremely small. On the premise of allowing the jacking block 406 to freely lift, the gap will not affect the stamping quality.

[0037] In order to enable the mutual approach of the clamping parts 504 to drive the two movable parts 4091 to approach each other, the bottom surface of the clamping rod 503 is provided with a blocking part 5031 in the present embodiment.
