Abstract (en)
[Problem] Provided is a technique for preventing a failure in which a blanking punch is pressed against an opening edge of a punch hole.[Solution] A die support mechanism 40 of the present disclosure includes a die holding member 41 through which a slit 41S passes, and a lower side of the die holding member 41 with respect to the slit 41S forms a die holding base 42 that holds a blanking die 32, and an upper side with respect to the slit 41S forms a ceiling portion 43 having a ceiling hole 44 concentric with a punch hole 32A of the blanking die 32. Then, the die holding member 41 is supported by the support base 50 in a horizontally slidable manner, and a guide portion of the ceiling hole 44 is in sliding contact with the blanking punch 31, whereby the die holding member 41 slides to a position where the punch hole 32A is centered on the blanking punch 31.
