ABSTRACT:
A multiple punching machine for punching out holes in the partition walls of a battery box. To accommodate all the different sizes and shapes and dimensions of battery boxes, the machine has multiple punching heads which are independently operated and independently positioned longitudinally, laterally, and vertically. Each head consists of a pair of pivoted punch jaws of small transverse dimensions to fit into small battery cells and each head is operated by an independent pneumatic ram with the piston rod moving along the length of the limbs of the jaw to minimize transverse diemensions. By using independent heads the reaction force at each punch is absorbed thus eliminating a heavy frame.
