ABSTRACT:
Conventional press brake female dies which have to be manually adjusted are not adaptable to today's automated factories for producing different shaped components on a demand basis. The subject apparatus overcomes this problem by providing powered, adjustable female die jaws that are positively located by powered rotary shims having several thicknesses to be presented according to the desired opening between the jaws. The power source for adjusting the jaws and the rotary shims may be controlled electronically to adjust the jaws to a position to produce a prescribed shape from a plate of metal.
