The driving member 41 drives the pressing plate 42 to move along the second direction Y to drive the pressing mechanism 50 and the punch 61 to move simultaneously, the pressing mechanism 50 presses the die plate 200, and the punching mechanism 60 punches the side plate 220 of the die plate 200 to form a bolt hole on the side plate 220 of the die plate 200. By positioning the positioning mechanism 30 and the pressing mechanism 50, the position of the die plate 200 can be kept stable, so that the accuracy of the blanking die plate 200 can be improved.

In addition, those skilled in the art will recognize that the foregoing embodiments are merely illustrative of the present application and are not intended to be limiting, as appropriate modifications and variations of the foregoing embodiments are within the scope of the present disclosure.
