[0023] Please see Figure 1-3 In this embodiment of the present invention, an automotive sheet metal stamping and deformation device includes a base plate 1, four support feet 2 fixedly connected to the bottom of the base plate 1, two side plates 4 fixedly connected to the top of the base plate 1, a top plate 5 fixedly connected between the upper ends of the two side plates 4, an electric push rod 6 fixedly connected to the bottom of the top plate 5, an upper template 8 fixedly connected to the extended end of the electric push rod 6, a protrusion 9 fixedly connected to the bottom of the upper template 8, a pressing and limiting structure at the bottom of the upper template 8, an oil spraying structure on the side wall of the upper template 8, a lower template 10 fixedly connected to the top of the base plate 1, a groove 3 opened at the top of the lower template 10, and the groove 3 is adapted to the protrusion 9.

[0024] Please see Figure 1-3The extrusion limiting structure includes four first springs 11, all of which are fixedly connected to the bottom side wall of the upper template 8. The bottom of the four first springs 11 is fixedly connected to a pressure plate 12. The side wall of the pressure plate 12 has a through hole, and the protrusion 9 is slidably connected in the through hole. When the upper template 8 moves downward, the pressure plate 12 will move, so that the pressure plate 12 abuts against the top of the sheet metal part, thereby extruding and limiting the sheet metal part.

[0025] Please see Figure 1-3 The spraying structure includes two oil reservoirs 7, both made of transparent material. Both reservoirs 7 are fixedly connected to the top side wall of the upper template 8. Two push rods 13 are slidably connected to the bottom of the upper template 8. Each push rod 13 has a baffle 14 fixedly connected to its bottom. A second spring 15 is fitted onto the outer side wall of each push rod 13. Four first springs 11 and two second springs 15 are made of stainless steel. The two second springs 15 are fixedly connected at both ends to the side walls of the upper template 8 and the corresponding baffle 14. The tops of both push rods 13 penetrate the upper template 8 and the corresponding oil reservoir 7. A sealing plate 17 is fixedly connected to the top of each push rod 13. The bottoms of both oil reservoirs 7 are fixedly connected to the upper template 8 and the corresponding oil reservoir 7. Two oil guide pipes 16 are fixedly connected, with one end of each pipe passing through the upper template 8 and abutting against both sides of the protrusion 9. Two sealing plates 17 abut against the top of the two oil guide pipes 16 respectively. When the pressure plate 12 moves, it will squeeze the two baffles 14. The two baffles 14 drive the sealing plates 17 to move through the push rod 13, so that the sealing plates 17 are released from the blockage of the oil guide pipes 16. The lubricating oil in the oil storage box 7 will flow to the side wall of the protrusion 9 through the oil guide pipes 16, thereby reducing the wear between the protrusion 9 and the sheet metal part and preventing wear on the surface of the sheet metal part. After stamping, the electric push rod 6 is activated to drive the upper template 8 to reset. The second spring 15 can drive the push rod 13 to reset, so that the sealing plates 17 block the oil guide pipes 16.

[0026] The working principle of this utility model is as follows: The sheet metal part to be stamped is placed on the top of the lower template 10. By activating the electric push rod 6, the extended end of the electric push rod 6 drives the upper template 8 to move downward. The upper template 8 drives the protrusion 9 to move, thereby stamping the sheet metal part. The pressure plate 12 is set up. When the upper template 8 moves downward, it will drive the pressure plate 12 to move, so that the pressure plate 12 abuts against the top of the sheet metal part, thereby squeezing and limiting the sheet metal part. When the pressure plate 12 moves, it will squeeze the two baffles 14. The two baffles 14 drive the sealing plate 17 to move through the push rod 13, so that the sealing plate 17 is released from the blockage of the oil guide pipe 16. The lubricating oil in the oil storage box 7 will flow to the side wall of the protrusion 9 through the oil guide pipe 16, thereby reducing the wear between the protrusion 9 and the sheet metal part and preventing wear on the surface of the sheet metal part. After stamping is completed, the electric push rod 6 is activated to drive the upper template 8 to reset. The second spring 15 can drive the push rod 13 to reset, so that the sealing plate 17 blocks the oil guide pipe 16.

[0027] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
