[0027] Embodiment

[0028] Referring to Figures 1 - 5 , for an embodiment of the present utility model, a mechanical stamping device for automobile part processing is provided, including: a stamping unit 100 and a shaping unit 200;

[0029] Among them, the stamping unit 100 includes a stamping table 101 and a support frame 102 fixedly connected to the top of the stamping table 101. A hydraulic telescopic rod 103 is fixedly installed at the top of the inner wall of the support frame 102. The output end of the hydraulic telescopic rod 103 is fixedly connected to a fixing plate 104. A plurality of stamping rods 105 are fixedly connected to the bottom of the fixing plate 104. A top die 106 is slidably arranged at the bottom of the plurality of stamping rods 105. During use, the fixing plate 104 is driven to descend by the hydraulic telescopic rod 103, and the top die 106 is descended by the fixing plate 104 to perform stamping.

[0030] The shaping unit 200 includes a bottom die 201 fixedly installed on the top of the stamping table 101. A plurality of stamping grooves 202 adapted to the stamping rods 105 are formed in the inner wall of the bottom die 201. A recovery box 203 is fixedly connected to the bottom of the stamping table 101. A plurality of tapered holes 204 are formed in the top of the stamping table 101, and the plurality of tapered holes 204 are respectively located directly below the plurality of stamping grooves 202. A pneumatic component 205 for stamping and demolding automobile parts is arranged on the stamping table 101. A groove adapted to the top die 106 is formed in the top of the bottom die 201. By placing a steel plate in the groove of the bottom die 201 and using the top die 106 to stamp the steel plate, a hub cap is stamped and shaped.

[0031] During use, the hydraulic telescopic rod 103 drives the upper die 106 to descend, and the steel plate is stamped and shaped into a hub cap by the upper die 106 and the lower die 201. After the upper die 106 and the lower die 201 are in full contact, the stamping rod 105 will be extruded by the fixing plate 104. The inner cavity of the upper die 106 is designed to be hollow, so that the stamping rod can move downward along the inner cavity of the upper die 106. At this time, the bottom end of the stamping rod 105 protrudes from the lower surface of the upper die 106. Through the stamping groove 202, the stamping rod 105 can punch through holes for installation in the steel plate. The steel sheet cut by the stamping rod 105 falls into the recycling box 203 through the conical hole 204 for recycling and utilization.

[0032] In addition, the pneumatic component 205 includes an airbag 2051 fixedly installed at the top of the inner wall of the support frame 102. A hose 2052 is fixedly connected to the side of the airbag 2051. A cylinder 2053 is fixedly connected to the bottom of the stamping table 101. The hose 2052 penetrates and extends to the bottom of the stamping table 101, and the end of the hose 2052 is connected to the cylinder 2053. A plurality of limiting blocks 206 are fixedly connected to the inner wall of the support frame 102. A circular groove is provided inside the limiting block 206. The hose 2052 is located in the circular groove of the limiting block 206. A lifting rod 2054 is slidably arranged in the inner cavity of the cylinder 2053. The top of the lifting rod 2054 penetrates the bottom of the stamping table 101. A through groove adapted to the lifting rod 2054 is provided in the inner wall of the lower die 201. The pneumatic component 205 is used to demold the stamped hub cap to facilitate the worker to take out the hub cap from the lower die 201;

[0033] During use, when the hydraulic telescopic rod 103 rises, the fixing plate 104 squeezes the airbag 2051. The gas inside the airbag 2051 is conveyed into the cylinder 2053 through the hose 2052. The limiting block 206 is used to limit the position of the hose 2052 so that it will not affect the stamping operation. The top of the lifting rod 2054 is flush with the bottommost surface of the inner wall of the lower die 201 so that it will not affect the steel plate during the stamping process. The lifting rod 2054 is designed in an I shape. A sealing ring is sleeved on the bottom of the lifting rod 2054. Gas is conveyed to the cylinder 2053 through the hose 2052 to make the lifting rod 2054 rise and push the stamped hub cap upward to facilitate the worker to take it out. When the fixing plate 104 is no longer in contact with the airbag 2051, the lifting rod 2054 descends by its own gravity, and the gas also flows back into the airbag 2051 to automatically restore it.

[0034] Furthermore, a fixing frame 207 is fixedly installed on the top of the stamping table 101. Sliding grooves are formed on both sides of the fixing frame 207. A T-shaped plate 208 is slidably arranged between the two sliding grooves. A circular through groove is formed on the top of the T-shaped plate 208. A discharging plate 209 is fixedly installed on the top of the stamping table 101. Baffles are fixedly connected to both sides of the discharging plate 209. The top of the discharging plate 209 is flush with the top of the upper die 106. A feeding cylinder 210 is fixedly installed on the top of the fixing frame 207. The feeding cylinder 210 is of a hollow design and is located above the T-shaped plate 208. By placing a plurality of steel plates in the feeding cylinder 210 and pushing the T-shaped plate 208, the stamped hub caps can be pushed to the discharging plate 209, and new steel plates can be replenished.

[0035] By pulling the T-shaped plate 208 to make the circular through groove of the T-shaped plate 208 located directly below the feeding cylinder 210, the thickness of the T-shaped plate 208 does not exceed the thickness of the steel plate, so that only one steel plate can fall into the circular through groove. Then, the T-shaped plate 208 is pushed to push the hub cap lifted by the lifting rod 2054 onto the discharging plate 209. Then, the circular through groove of the T-shaped plate 208 moves directly above the lower die 201, so that the steel plate can fall into the lower die 201 for convenient stamping. By pulling the T-shaped plate 208 to make its circular through groove move directly below the feeding cylinder 210 again, the process of feeding and discharging can be completed quickly and conveniently, which is convenient for workers to use.

[0036] During the use process, by placing a plurality of steel plates in the feeding cylinder 210 and pushing the T-shaped plate 208 with the steel plates, the steel plates in the T-shaped plate 208 can fall into the lower die 201. Then, the T-shaped plate 208 is pulled again to make the circular through groove of the T-shaped plate 208 move directly below the feeding cylinder 210 to replenish new steel plates. Subsequently, the upper die 106 is driven to descend by the hydraulic expansion rod 103. The steel plate is stamped and shaped into a hub cap by the upper die 106 and the lower die 201, and the stamping rod 105 can punch through holes for installation in the steel plate through the stamping groove 202.

[0037] The steel sheets cut by the stamping rod 105 fall into the recycling box 203 through the conical hole 204. Then, the fixing plate 104 is raised to squeeze the airbag 2051. The gas inside the airbag 2051 is conveyed into the air cylinder 2053 through the hose 2052, so that the gas is used to push the lifting rod 2054 to rise and push the stamped hub cap upward. When the fixing plate 104 is no longer in contact with the airbag 2051, the lifting rod 2054 descends by its own gravity, and the gas also flows back into the airbag 2051 to automatically restore it.

[0038] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and all of them should be covered by the scope of the claims of the present invention.
