In this context, automotive sheet metal work is equivalent to automotive sheet metal repair, which refers to the repair of a car body after a collision. This includes all work except for anti-corrosion and decorative painting of the car body.
[0003] In the production and processing of automotive sheet metal, molds are used. The cooperation between the upper and lower molds enables the stamping of automotive sheet metal. After the automotive sheet metal is processed, it needs to be removed from the lower mold. When removing the automotive sheet metal, it needs to be disconnected from the bottom of the lower mold. Because the automotive sheet metal is in close contact with the lower mold, it is very easy for the automotive sheet metal to be damaged when it is removed. The high temperature after automotive sheet metal production and processing makes it difficult for the operator to remove the automotive sheet metal during the blanking process, which in turn affects the blanking of automotive sheet metal.

A movable plate 18 is fixedly installed on the guide block 16, and a pressure rod 19 that extends into the lower mold 3 and applies pressure to the movable cylinder 7 is fixedly installed on the movable plate 18. The guide rod 15 guides the guide block 16, so that the guide block 16 can smoothly pull the movable plate 18 and the pressure rod 19 when it moves. The spring 17 buffers the guide block 16. When the pressure plate 25 is disconnected from the movable plate 18, the moving speed of the movable plate 18 and the pressure rod 19 is limited. A pressing component for pressing the movable plate 18 is installed on the support plate 5.
[0024] The guide rod 15 is vertically set, and the second spring 17 is sleeved on the guide rod 15. The moving plate 18 is horizontally set on both sides of the support plate 5. The pressing component includes a fixed plate fixedly installed on the support plate 5, and a motor 20 is fixedly installed on the fixed plate. The output end of the motor 20 is fixedly connected to the first rotating shaft 21. After the motor 20 is powered on, it drives the first rotating shaft 21 to rotate. This technical solution is existing technology and will not be elaborated on here. The fixed plate is rotatably installed with the second rotating shaft 22, which is connected to the first rotating shaft 21.

[0025] Rotary shaft 1 21 and rotary shaft 22 are horizontally arranged correspondingly, and gear 1 23 and gear 24 are fixedly installed on rotary shaft 1 21 and rotary shaft 22 respectively. Gear 1 23 and gear 24 are spur gears with the same number of teeth, and rotary shaft 1 21 and rotary shaft 22 can drive in opposite directions at the same speed.
[0026] The lower mold 3 is fixedly installed with symmetrically arranged fixing rods 11, and a moving block 12 for cutting automotive sheet metal is slidably sleeved on the fixing rod 11. A bonding plate 13 corresponding to the lower mold 3 is integrally connected to the moving block 12. The fixing rods 11 guide the moving block 12 so that the moving block 12 can smoothly pull the bonding plate 13 when moving.
[0027] The fixing rod 11 is vertically set on both sides of the lower mold 3. The support plate 5 is fixedly installed with the support rod 26, and the positioning pin 27 is rotatably installed on the support rod 26. The fitting plate 13 is provided with the positioning groove 14 that cooperates with the positioning pin 27. When the automotive sheet metal needs to be cut, the positioning pin 27 can extend into the positioning groove 14 when it rotates. When the support plate 5 moves up, it drives the moving block 12 and the automotive sheet metal to move up. The automotive sheet metal moves to the opening of the lower mold 3, which makes it more convenient for the operator to cut the automotive sheet metal.
[0028] The functional principle of this utility model can be explained through the following operation methods:
[0029] Place the automotive sheet metal to be processed into the lower mold 3;
[0030] The output end of motor 20 drives shaft 21 to rotate. When shaft 21 rotates, it drives shaft 22 to rotate through gear 23 and gear 24. When shaft 21 and shaft 22 rotate, they drive pressure plate 25 to move against moving plate 18. Moving plate 18 drives guide block 16 to slide on guide rod 15. Spring 27 is stressed, causing moving plate 18 to drive pressure rod 19 to move down.
[0031] The hydraulic cylinder 4 extends and retracts, causing the support plate 5 and the upper die 6 to move down. First, after the support plate 5 moves down, the pressure rod 19 presses the moving cylinder 7. When the moving cylinder 7 slides in the guide hole 8, it causes the lifting plate 10 to move down. The spring 19 is under force. When the lifting plate 10 is limited, the upper die 6 and the lower die 3 cooperate to stamp the automotive sheet metal.
[0032] After the automotive sheet metal processing is completed, the traction positioning pin 27 is rotated. When the positioning pin 27 rotates, it extends into the positioning groove 14. The output end of the hydraulic cylinder 4 drives the support plate 5 and the upper mold 6 to move upward. After the support plate 5 moves upward, it drives the bonding plate 13 to move upward through the support rod 26. The bonding plate 13 moves upward, causing the moving block 12 and the automotive sheet metal to move upward. The automotive sheet metal moves out of the opening of the lower mold 3, and the operator takes out the automotive sheet metal.
