[0003] In the prior art, patent CN218015162U discloses an automatic punching positioning die. This technical solution limits the steel strip through a guide groove, and the roller is pressed on the surface of the steel strip. The steel strip can move linearly under the roller. The pressing effect of the roller on the steel strip can make the steel strip always fit on the surface of the lower die seat, thereby improving the positioning effect of the steel strip, preventing the steel strip from warping up, and ensuring the punching processing accuracy.
