Abstract:
A workpiece manufacturing apparatus includes a punch, which is provided in a lower die assembly and punches out a workpiece from an unprocessed material, and an ejector, which is provided in an upper die assembly so as to be capable of approaching and moving away from the lower die assembly. The manufacturing apparatus further includes a spring, which is provided in the upper die assembly and urges the ejector toward the lower die assembly, and a locking device, which locks the ejector with respect to the upper die assembly at a position at which the punch punches out the workpiece and releases the ejector when the die assemblies are opened. The locking device includes an actuator, which is provided in the upper die assembly and slides a slider between a locking position, at which the ejector is locked, and a releasing position, at which the ejector is released.

Claim (Index 3):
The workpiece manufacturing apparatus according to  claim 2 , wherein\n the spring is configured by a first spring member and a second spring member provided in an urging mechanism, which urges the ejector toward the lower die assembly, the urging mechanism is configured to compress the first spring prior to the second spring when the ejector is displaced away from the lower die assembly, a force required to compress the first spring member is smaller than a force required to compress the second spring member, a displacement amount of the first spring member during compression is larger than a displacement amount of the second spring member during compression, a force with which the actuator slides the slider from the releasing position to the locking position is set to a magnitude that can push up the roller against the urging force of the first spring member along the slope of the slider and cannot push up the roller against the urging force of the second spring member, and when the upper die assembly and the lower die assembly are clamped, the control section operates the actuator to slide the slider from the releasing position to the locking position.
