Abstract
A reciprocating die roll forming machine for forming a pattern such as a thread form on the outer surface of a cylindrical blank includes at least one set of reciprocating dies operating upon the blank which rotates in place. The machine includes a slide and bearing combination to support the dies belt driven by a servo-motor controlled by a central processing unit. Mechanism is provided to deliver and position a blank for engagement by the dies. In one form, the machine includes multiple die sets to produce multiple parts during one die reciprocation cycle. In another form, the machine employs separate drive mechanisms to independently drive each die of a set.
