Punch head for a punch press |
摘要 |
A punch press (10) having a punching head (30) which includes a large eccentric crankshaft (42) for operating selected punches (32). The large eccentric crankshaft (42) withdraws the punch (32) into an upper tool support (92) for a relatively large portion of the crankshaft rotation. The crankshaft (42) is connected to a selected punch (32) by a suitable mechanical interposer. The upper tool support (92) is provided to hold a variety of punches (32) and is movable to bring a selected punch (32) into position for being operated by the punching head (30). A mechanism is provided for relative positioning of a workpiece and the punching head (30). Since the punch (32) is withdrawn within the upper tool support (92) for a relatively large portion of the crankshaft (42) rotation the movement of the workpiece can take place while the selected punch is moving but withdrawn within the upper tool support (92).
