The two groups of clamping plates 7 clamp and fix the two sides of the steel sheet under the elastic push of the first spring 6, and the two sides of the clamping plate 7 are subjected to the same force. Therefore, the steel sheet is automatically positioned at the middle position of the stamping groove 8 under the push of the balanced force, and the steel sheet is obliquely clamped by the setting of the clamping groove 9, so as to avoid warping of the two sides of the steel sheet during the clamping process. Then, the lifting frame 18 is controlled to press down, and the lifting frame 18 drives the punching head 19 to press down, so as to punch the steel sheet into the punching groove 8. At the same time, the lifting frame 18 drives the two groups of lifting rods 11 to press down synchronously, and the lifting rods 11 are driven by the first inclined wedge.
