[0002] Steel plate processing is a commonly used technology in the manufacturing industry. Steel plates can be processed by shearing, bending, stamping and other processing techniques. Different processing methods correspond to different processing techniques. Common processing methods for steel plates include steel plate cutting, steel plate welding, steel plate bending, steel plate punching, steel plate shearing, and steel plate surface treatment. Among them, steel plate surface treatment includes steel plate polishing, steel plate edge grinding, steel plate pickling, etc. In the process of steel plate processing, punching of steel plates is often required, which involves a punching machine for steel plate processing. The steel die punching process is to use the convex and concave dies made of tool steel to punch the pipe. According to the relationship between the direction of movement of the punch and the direction of movement of the slide of the press when the mold is working, steel die punching can be divided into two methods: vertical punching and horizontal punching.

[0003] However, most steel plates are punched by operators manually applying pressure with a punching handle, which is laborious and rough, and the punching operation cannot be automated. In addition, during the punching process, the steel plate will shift or deform due to the applied pressure, resulting in deviations in the punching position. The punching accuracy is not accurate enough, which reduces the efficiency of the punching work. Utility Model Content

The outer surfaces of both sides of the seat plate 43 are interlaced with spring shafts 45, and the bottom ends of the two spring shafts 45 are commonly fixedly connected with a pressing plate 46. When it is necessary to punch the steel plate, the motor 33 in the punching device 3 is started, and the output end of the motor 33 is started to drive the second shaft disc 34 to rotate between the two back plates 2. The rotating second shaft disc 34 drives the first shaft disc 32 to rotate through the belt 35, thereby driving the main shaft 3 1 is rotated, the rotating main shaft 31 drives the fixed plate 36 to rotate, and then drives the connecting shaft 37 located at the eccentric position to rotate, the connecting shaft 37 at the eccentric position drives the transmission plate 38 at one end to rotate eccentrically, and the rotation force drives the sliding plate 41 to slide up and down along the two slide rails 21 through the transmission shaft 39, and the sliding plate 41 drives the seat plate 43 fixedly connected to the fixed block 42 to move up and down, and under the stability of the two spring shafts 45 on both sides of the pressing plate 46, the punch 40 passes through the punching groove in the pressing plate 46.
