It is fixedly connected, the upper end in the punching portion is provided with the second upward punching knife of at least one edge of a knife, second punching
Knife is flexibly connected with the punching portion, and the edge of a knife of the second punching knife is in wave dentation, and the lower end of the second punching knife is set
It is equipped with block, the block is fixedly connected with punching portion.
Preferably, the size and shape of the first punching knife is identical as the second punching size and shape of knife.
Preferably, the vertical projection of the first punching knife is annular in shape.
Preferably, the vertical projection of the second punching knife is annular in shape.
Preferably, capaciting material groove is provided in the middle part of the first punching knife.
The beneficial effects of the utility model are: the utility model is by being provided at least one edge of a knife downward in punching portion
First punching knife and at least one edge of a knife upward second punching knife, punching portion during downlink, first punching knife realize
Cutting to plate, in uplink, the second punching knife cuts the waste material of plate rabbet lower part remnants in punching portion, is avoiding
While rabbet lower end deforms, decreases punching portion and the repetition of plate is punched, improve production efficiency, and save production
Cost.
