The initial position of the lifting plate 10 is located above the bottom groove 9. The workpiece to be punched is placed on the bottom die 6, and the lifter 15 is started to lower the top die 16. At this time, the punched workpiece will be located inside the die cavity 7. During this process, the lifting plate 10 will compress the spring 12, so that the lifting plate 10 will be located inside the bottom groove 9. When the top die 16 rises, the spring 12 will reset, which can provide an elastic force to the lifting plate 10, so that the lifting plate 10 can eject the punched parts in the die cavity 7. This process does not require manual material removal from the inside of the die cavity 7, which not only saves labor but also has high material removal efficiency.

[0025] When this structure is used, manual loading is required, which will waste labor. The front end of the processing table 1 is symmetrically provided with a driving shaft 2 and a driven shaft 3. The upper end of the processing table 1 is fixedly provided with a positioning frame 4 and a motor 5. The positioning frame 4 and the motor 5 are respectively located on both sides of the driving shaft 2. The rear ends of the driving shaft 2 and the driven shaft 3 are both provided with a positioning shaft rotatably connected to the positioning frame 4, and the driving shaft 2 is meshed with the driven shaft 3.
