<p>A hole punching device for punching holes at high productivity in the entire surface of a strip-like workpiece (W). The hole punching device (100) has a base (110), two workpiece feeding devices (210, 220) respectively having upper rollers (212, 222) and lower rollers (214, 224) and horizontally moving and positioning the workpiece (W) in the workpiece feeding direction (hereinafter referred to as one direction), and a hole punching mechanism (400). The hole punching mechanism (400) has a punching die (500) having a forming die (510) and a punching die (520) and placed between the two workpiece feeding devices (210, 220). The hole punching mechanism (400) is horizontally movable relative to the base (110) in the other direction normal to the one direction and is finely movable relative to the base (110) in the one direction.</p> |
