Abstract

A wire cutting and stripping mechanism (22) for use with a wire processing machine (10) is disclosed. The mechanism includes a pair of cutting and stripping blade (180, 182, 184) tool holders (60, 62) which are slidingly coupled to the frame (16) of the machine. The tool holders are arranged to move toward a wire (12) to be processed in two discrete amounts of movement which are separable by a pause in movement. A pair of cylinders (130, 132) are interconnected to effect these two discrete movements. During the first movement the wire 12 is severed, followed by a pause in movement while the cut wire is repositioned axially with respect to the stripping blades (182, 184). The second movement is then initiated to sever the insulation, the stripping blades (182, 184) being held in position while the wire is withdrawn to strip off the slug (196) of cut insulation.

Dependent claims

A wire cutting and stripping mechanism having a frame, first and second opposed tool holders on opposite sides of a wire path adapted for carrying wire cutting and stripping blades;

said first and second tool holders coupled to said frame by means of a first coupling and arranged to move toward said wire path in two discrete amounts of movements, separable by a pause in movement, upon actuation of said first coupling, and an actuator for effecting said actuation of said first coupling, said actuator comprising:
(a) a first cylinder having a first housing and a first piston rod extending therefrom, said housing of said first cylinder being attached to said frame;
(b) a second cylinder having a second housing and second piston rod extending therefrom in operational engagement with said first coupling;
(c) means for actuation of one of said first and second cylinders so that said first discrete movement is effected;
and
(d) means for actuation of the other of said first and second cylinders so that said second discrete movement is effected.
