[0002] Sheet metal is a metal product, usually made of materials such as thin steel plates, aluminum plates or stainless steel plates. They are processed into various shapes and sizes through processes such as stamping, bending and welding to meet different uses and requirements. Sheet metal stamping, also known as stamping, is a process that uses a lot of force to change the shape of a flat metal plate. It may also involve punching holes in the metal. This is a common processing technology, mainly used to produce metal parts of various shapes, but the existing sheet metal stamping dies do not have a structure for ejecting sheet metal parts. After the stamping die is used to process the sheet metal, the sheet metal is easily adhered to the die or the punch after being subjected to the strong pressure of the die. After adhesion, manual assistance is required to remove the material, which is not convenient for removing the sheet metal after stamping, affecting the subsequent stamping stability of the sheet metal.

The output end of the motor 17 drives the bidirectional screw 22 to rotate. When the bidirectional screw 22 rotates, it drives the outer movable slider 23 to move. When the movable slider 23 moves, it drives the sliding top plate 24 and the positioning clamping plate 25 to move. The two positioning clamping plates 25 position the stamping position of the sheet metal part on the top of the lower concave die 1. The output end of the hydraulic cylinder 5 drives the No. 1 movable plate 4, the mounting die base 7 and the upper punch 8 to move downward. Through the cooperation between the upper punch 8 and the lower concave die 1, the sheet metal part is stamped. After stamping, the output end of the hydraulic cylinder 5 drives the No. 1 movable plate 4, the mounting die base 7 and the upper punch 8 to move upward and reset. When moving upward, the air cylinder 5 is started. Cylinder 20, the output end of cylinder 20 drives the No. 2 movable plate 18 and the No. 2 ejector rod 19 to move downward, and the No. 2 ejector rod 19 is used to eject the stamped sheet metal at the bottom of the upper punch 8 to prevent adhesion. At the same time, when the No. 1 movable plate 4 moves upward, the ejector plate 10 on the top of the pull rod 9 is pushed, and the No. 1 movable plate 4 pulls the pull plate 10 and the pull rod 9 to move upward. The pull rod 9 drives the fixed side plate 14 and the pull plate 13 to move upward. When the pull plate 13 moves upward, it drives the No. 1 ejector rod 16 to move upward. The pull plate 13 presses the spring 15. When the No. 1 ejector rod 16 moves upward, it pushes the stamped sheet metal in the lower die 1 to prevent the sheet metal from sticking to the lower die 1 after stamping. The spring 15 facilitates the resetting of the pull plate 13, the fixed side plate 14, the pull rod 9 and the ejector plate 10.
