After the adjustment is completed, the stamping cylinder 31 is started, the movable plate 34 and the punching shear head 32 are driven downward by the cylinder shaft to punch and shear the material. The guide sleeve 4 limits the movement direction of the punch holder 3 during the whole process, ensuring the accuracy of the stamping, and finally realizing efficient and accurate punching and shearing of materials of different thicknesses.
