Abstract
In an upper tool, a stripper plate (35) is disposed movably up and down at a lower end portion (13a) of a punch guide (13) for housing a punch (27) also movably up and down, via a shock damping member (33). Further, the shock damping member (33) is formed into an annular body disposed so as to enclose an annular gap (X) formed between the lower end portion (13a) of the punch guide (13) and the upper surface (65) of the stripper plate (35). The upper tool can reduce noise sound generated during punching processing, and further prevent chips produced during punching processing from adhering onto the workpiece and the shock damping member, thus protecting the workpiece from being scratched by the chips and further improving the life time of the shock damping member.
