[0031] Please see Figure 1-6 As shown, the present invention provides a stamping device for automotive parts, including a stamping table 1, a plurality of support legs 2 fixedly connected to the bottom of the stamping table 1, and a lower mold 3 installed on the top of the stamping table 1. A stamping groove 4 is provided on the top of the lower mold 3, and automotive part sheet metal to be stamped can be placed in the stamping groove 4. A fixing frame 5 is provided above the lower mold 3, and the bottom of the fixing frame 5 is fixedly connected to the stamping table 1. Positioning components are provided on both sides of the fixing frame 5, and a stamping mechanism is provided on the top of the fixing frame 5. A material ejection mechanism is provided at the bottom of the stamping table 1.

[0032] The positioning assembly includes a first electric telescopic rod 6, which is installed on the side wall of the fixed frame 5. A positioning plate 7 is fixedly connected to the end of its output shaft. The positioning plate 7 can be moved by driving the first electric telescopic rod 6. When the positioning plate 7 is attached to the side wall of the automotive part sheet, the part sheet can be clamped and positioned by the positioning plate 7 to prevent the position of the part sheet from shifting during the stamping process and affecting the stamping accuracy.

[0033] The stamping mechanism includes a hydraulic cylinder 8, which is mounted on the top of the fixed frame 5. The bottom end of its output shaft is fixedly connected to a lifting plate 9. An upper mold 10 is mounted on the bottom of the lifting plate 9. By driving the hydraulic cylinder 8, the lifting plate 9 and the upper mold 10 can be moved up and down together. When the upper mold 10 comes into contact with the automotive part sheet in the stamping groove 4, the pressure applied by the upper mold 10 can cause the part sheet to undergo plastic deformation or separation in order to obtain automotive parts of the required shape and size.

[0034] The ejector mechanism includes a bracket 11, which is fixedly connected to the bottom of the stamping table 1. A second electric telescopic rod 12 is installed on its upper bottom surface. The top end of the output shaft of the second electric telescopic rod 12 passes through the bottom of the stamping table 1 and the lower mold 3 and is fixedly connected to an ejector plate 13. The ejector plate 13 is located in the stamping groove 4. By driving the second electric telescopic rod 12, the ejector plate 13 can be moved up and down. After the stamping of the automotive parts is completed, the ejector plate 13 can eject the stamped automotive parts out of the stamping groove 4 to complete the automatic unloading without the need for manual removal by the staff. This not only greatly improves work efficiency but also effectively reduces the workload of the staff.

[0035] The positioning plate 7 has an anti-slip pad 14 on its surface. The anti-slip pad 14 has a herringbone anti-slip pattern on its surface. The anti-slip pad 14 can be made of elastic materials such as rubber and is fixed by means of glue. When the positioning plate 7 is attached to the side wall of the component plate, the anti-slip pattern on the surface of the anti-slip pad 14 can increase the friction between the component plate and the positioning plate 7, so as to play an anti-slip role and prevent the component plate from slipping and shifting.

[0036] The lifting plate 9 has connecting blocks 15 fixedly connected to both sides, and a guide tube 16 fixedly connected to the end of the connecting block 15. A pair of guide rods 17 are fixedly connected to the lower top surface of the fixing frame 5. The diameter of the guide rod 17 is equal to the inner diameter of the guide tube 16, and each guide rod 17 passes through the corresponding guide tube 16. When stamping the automotive part sheet in the stamping groove 4, the lifting plate 9 can drive the connecting block 15 and the guide tube 16 to move up and down along the guide rod 17. At this time, the mutual cooperation between the guide tube 16 and the guide rod 17 can play a limiting and guiding role, so as to improve the stability of the lifting plate 9 and prevent it from shaking and tilting during the up and down movement, which would affect the stamping accuracy of the upper mold 10.

[0037] The upper mold 10 is located directly above the stamping groove 4, and an upper protective pad 18 is provided on the bottom surface of the upper mold 10. The upper protective pad 18 can be made of elastic materials such as rubber and is fixed by means of glue. When the upper mold 10 comes into contact with the automotive part sheet, the upper protective pad 18 can play a buffering and protective role to prevent the upper mold 10 from applying too much pressure and causing damage to the part sheet.

[0038] The upper mold 10 has several positioning seats 19 fixedly connected to both sides. Each positioning seat 19 has a positioning post 20 fixedly connected to its top. The post 20 has an external thread and is threaded with a nut 21 that matches it. The surface of the lifting plate 9 has several positioning holes 22. The number of positioning holes 22 is the same as that of the positioning seats 19. The diameter of the holes corresponds to the diameter of the positioning post 20. The center of each positioning hole 22 corresponds to the center of each positioning post 20. Each positioning post 20 can be aligned and pass through the corresponding positioning hole 22. At this time, the nut 21 is threaded onto each positioning post 20 and tightened. The upper mold 10 can be positioned and fixed by the mutual cooperation between the positioning post 20, the positioning hole 22, and the nut 21 to ensure that the upper mold 10 can be accurately installed above the stamping groove 4. When the upper mold 10 is worn due to long-term use, the upper mold 10 can be removed from the lifting plate 9 by unscrewing the nut 21 for quick replacement.

[0039] Both the top plate 13 and the stamping groove 4 are rectangular, with equal length and width. The top surface of the top plate 13 is provided with a lower protective pad 23. The lower protective pad 23 can be made of elastic materials such as rubber and is fixed by means of glue. When the stamping mechanism stamps the automotive part sheet in the stamping groove 4, the lower protective pad 23 can play a wear-resistant protection role to prevent the bottom of the part sheet from directly contacting the bottom of the stamping groove 4 and causing wear.

[0040] The top plate 13 has a reinforcement cavity 24 inside, and a number of reinforcing ribs 25 are provided inside the reinforcement cavity 24. The reinforcing ribs 25 are X-shaped, and their top and bottom are fixedly connected to the top and bottom of the inner cavity of the reinforcement cavity 24, respectively. The reinforcing ribs 25 are distributed linearly at equal intervals along the length of the reinforcement cavity 24. The structure of the top plate 13 can be reinforced by multiple reinforcing ribs 25, so as to improve the structural strength of the top plate 13 and prevent it from bending and deforming after being subjected to force for a long time, thus affecting its service life.

[0041] The circuits, electronic components, and chip modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and methods.

[0042] All standard parts used in the application documents can be purchased from the market. All components in this application documents can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art.

[0043] The working principle of this utility model is as follows:

[0044] In use, the automotive part sheet to be stamped can be placed in the stamping groove 4 at the top of the lower mold 3. Then, the first electric telescopic rod 6 is driven to move the positioning plate 7 until it is in contact with the side wall of the automotive part sheet. At this time, the positioning plate 7 can clamp and position the part sheet. Next, the hydraulic cylinder 8 is driven to move the lifting plate 9 and the upper mold 10 downward together until the upper mold 10 contacts the automotive part sheet in the stamping groove 4. At this time, the pressure applied by the upper mold 10 can cause the part sheet to undergo plastic deformation or separation. The upper mold 10 is designed to be disassembled to obtain automotive parts of the required shape and size. After the stamping of the automotive parts is completed, the second electric telescopic rod 12 can drive the top plate 13 to move upward so that the stamped automotive parts can be ejected from the stamping groove 4 through the top plate 13, thereby completing the automatic unloading without the need for manual removal by the staff. This not only greatly improves work efficiency but also effectively reduces the workload of the staff. When the upper mold 10 is worn due to long-term use, the upper mold 10 can be removed from the lifting plate 9 by unscrewing the nut 21 so that the upper mold 10 can be quickly replaced.
