Abstract
Description
Technical Field
[0001] This utility model relates to the field of riveting technology, specifically to a plate riveting punch. Background Technology
[0002] In the semiconductor component manufacturing industry, many boards are used for transporting wafers, such as molybdenum plates. These plates involve numerous riveting processes, and poor riveting can lead to wafer breakage during transport. The boards have multiple riveting grooves, each with a bottom hole at its center. O-rings and discs with center holes need to be placed within the grooves, and then riveted into the grooves. The O-rings protrude from the bottom holes. Current technology lacks suitable riveting punches, resulting in low product yield, inability to achieve one-time riveting, and low production efficiency. Therefore, a new technical solution is urgently needed to address at least one of these technical problems. Summary of the Invention
[0003] The purpose of this utility model is to provide a plate riveting punch, which uses a positioning pin to cooperate with the center hole for positioning, the punch to press the edge of the riveting groove, and the thrust mechanism to push the disc, thereby riveting in one step, improving production efficiency and product yield.
[0004] In order to achieve the above technical objectives and meet the above technical requirements, the technical solution adopted by this utility model is: a plate riveting punch, characterized in that it includes a stamping block with a stamping end, a plurality of punches disposed on the stamping end, a positioning pin disposed on one end of the stamping block, and a thrust mechanism sleeved on the positioning pin.
[0005] As a preferred technical solution, the thrust mechanism includes at least one elastic thrust ring sleeved on the positioning pin.
[0006] As a preferred technical solution, the diameter of the punch gradually decreases from the root to the head.
[0007] As a preferred technical solution, the stamping end is tapered.
[0008] As a preferred technical solution, the number of punches is 4, and the 4 punches are evenly arranged in a circumferential array, with the positioning pin located at the center of the stamping end.
[0009] As a preferred technical solution, the inclination angle of the stamping end is 30°.
[0010] As a preferred technical solution, the thrust mechanism includes two elastic thrust rings sleeved on the positioning pin.
[0011] As a preferred technical solution, the elastic thrust ring is made of rubber.
[0012] As a preferred technical solution, the hardness of the stamping block is greater than or equal to 55HRC.
[0013] As a preferred technical solution, the punch head is tapered.
[0014] The beneficial effects of this utility model are:
[0015] 1) Positioning is achieved by the positioning pin engaging with the center hole, the punch presses the edge of the riveting groove, and the thrust mechanism pushes the disc to form a single riveting, thereby improving production efficiency and product yield.
[0016] 2) The elastic thrust ring squeezes the disc to generate elastic force, thereby pushing the disc to squeeze the O-ring out of the bottom hole. At the same time, because the elastic thrust ring is elastic, it will not damage the surface of the disc.
[0017] 3) The diameter of the punch gradually decreases from the root to the head, increasing the strength of the punch root and preventing the punch from breaking;
[0018] 4) The tapered stamping end serves to avoid damage to the molybdenum plate.
[0019] 5) The punch head is tapered, which provides a better effect of pressing the edge of the riveting groove. Attached Figure Description

[0026] The present invention will now be further described with reference to the accompanying drawings.
[0027] In the accompanying drawings of this utility model, the same or similar reference numerals correspond to the same or similar components. In the description of this utility model, it should be understood that if terms such as "head," "tail," "top," "bottom," "left," "right," "front," "rear," "inner," and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, they are only for the convenience of describing this utility model, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this patent. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.
[0028] Please see Figures 1-5 This utility model provides a riveting punch for a plate 5, including a stamping block 1 with a stamping end 101, a plurality of punches 2 disposed on the stamping end 101, a positioning pin 3 disposed on one end of the stamping block 1, and a thrust mechanism sleeved on the positioning pin 3. The plate 5 has a plurality of circular riveting grooves 501, and a bottom hole 502 is provided at the center of the bottom surface of the riveting groove 501. An O-ring 7 and a disc 6 are placed in the riveting groove 501. A center hole 601 is provided at the center of the disc 6. The positioning pin 3 extends into the center hole 601 to form a positioning. The punches 2 punch the edge of the riveting groove 501 to deform the edge of the riveting groove 501, thereby fixing the disc 6. The thrust mechanism pushes the disc 6 to squeeze the O-ring 7. The O-ring 7 protrudes from the bottom hole 502, thereby riveting in one step, improving production efficiency and product yield.
[0029] like Figures 1-5 As shown, the thrust mechanism includes at least one elastic thrust ring 4 sleeved on the positioning pin 3. Specifically, the thrust mechanism includes two elastic thrust rings 4 sleeved on the positioning pin 3. The elastic thrust rings 4 are made of rubber, elastic plastic, or silicone. Preferably, the elastic thrust rings 4 are made of rubber, which has good elasticity, and the shape of the elastic thrust rings 4 is O-shaped.
[0030] like Figures 1-5 As shown, the diameter of the punch 2 gradually decreases from the root to the head, which increases the strength of the root of the punch 2 and prevents the punch 2 from breaking.
[0031] like Figures 1-5 As shown, the stamping end 101 is tapered, which increases the strength of the root of the punch 2 and prevents the punch 2 from breaking. Specifically, the inclination angle of the stamping end 101 is 30°. At this time, the stamping end 101 has high strength and reasonable stress.
[0032] like Figures 1-5As shown, the number of punches 2 is 2, 3 or 4, and the 4 punches 2 are evenly arrayed in a circle. The positioning pin 3 is located at the center of the stamping end 101. In this way, the punches 2 can form multiple pressure pits on the edge of the riveting groove 501, which has a good fixing effect on the circular piece 6.
[0033] like Figures 1-5 As shown, the hardness of the stamping block 1 is greater than or equal to 55HRC, which improves impact resistance and extends service life.
[0034] like Figures 1-5 As shown, the head of the punch 2 is tapered, which makes the punch 2 better at pressing the edge of the riveting groove 501 and easier to form a dent.
[0035] The above embodiments are merely descriptions for clearly illustrating the present utility model, and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all implementations here, and the obvious variations or modifications derived therefrom are still within the protection scope of the present utility model.
