Abstract

PURPOSE: To provide a method of punching plate members wherein poor adhesion, etc. due to punching oils is eliminated in punching the plate members by providing a concaved groove coinciding with the punching shape, leaving a punching oil to this section, and punching the plate members in such conditions as coated with the punching oil.
CONSTITUTION: Above a punching die 1, there are provided a punching oil 3- coating unit 17, a grooving punch 5, a wiper device 18 and a punch 6 in that order in the plate member 2 feed direction. Projected grooving streaks 20 coinciding with the outer shape of the punch 6 are provided in the grooving punch 5 so as to engrave a groove 4 at the surface of the plate member 2 uniformly coated with the punching oil 3. The oil is wiped off by the wiper devide 18, and remains only in the groove 4. The plate member 2 is punched at the groove section by the punch 6, dropping through a shoot 13, and being coated with an adhesive agent 8.
