Workpiece forming machine

摘要

A high compression forming machine for forming workpieces such as nuts or like objects includes a toggle action subassembly for operating a Geneva-driven opposed-rams-press and cooperant vertically-disposed multiposition bolster or turret rotatably mounted relative to a frame about a horizontally-extending central axis and having a plurality of spaced, arcuately-arranged horizontally-extending work-receiving cavities extended therethrough, the center of each cavity being located with equal circular pitch along the circumference of a circle and allocated in order of successive operations in the work-forming process. It sequentially deforms workpieces through a simultaneous application thereto of opposing mechanical forces at opposite ends of the workpieces in a step-by-step manner as the bolster is sequentially rotated through a series of stations. The center of each cavity is located with equal circular pitch along the circumference of a circle and about a drive shaft adapted to transmit the intermittent rotary motion giving the step-by-step operation, the cavities being allocated in order of successive operations in the work-forming sequence.
