Abstract

The present invention relates to a ram actuating mechanism in a press for terminating wires, or the like. The actuating mechanism imparts movement to the ram in two distinct portions. An air cylinder or other low pressure linear actuator is utilized to effect the relatively long stroke of the first portion of movement. The second portion of movement, which must overcome relatively high insertion forces but over a relatively short distance is effected by a cam and cam follower arrangement. This permits sufficient clearance between the terminating punch and die when the ram is retracted to pass other wire handling mechanisms while at the same time providing a relatively compact mechanism.

Dependent claims

In a press for terminating wires, having a frame, a base, and a ram, said ram and base being associated with said frame and arranged for mutually opposed reciprocating movement with respect thereto,

actuating means for effecting said reciprocating movement comprising a first linkage means for causing a first portion of said movement and a second linkage means for causing a second portion of said movement which effects said termination, wherein said first portion of movement occurs over a substantially greater distance than does said second portion of movement, said second linkage means including a barrel cam having a camming surface circumscribing the cam 360.degree. and cam follower operationally engaged therewith for effecting said second portion of movement, said second linkage means further including means for driving said cam one complete revolution of 360.degree..
