Powered wire stripper
First Claim
1. A powered wire stripper, comprising:
- a housing including first and second frame members and right and left covers, and having at least one wire-receiving opening at one end for receiving wire to be stripped;
a cylinder connected to the housing and having a piston movable therein with a piston rod connected to the piston extending from the cylinder to the housing;
a valve for supplying pressure fluid to the cylinder on either side of the piston;
a pair of blade holders pivotable about at least one pivot pin between open and closed conditions, the blade holders and pivot pin being slidable in the housing between ready and retract positions;
first and second blades mounted in opposing relation on the blade holders and cooperating when the blade holders are closed to cut the insulation of a wire inserted into the wire-receiving opening;
at least one puller plate which is connected to the piston rod and slidable in the housing along a longitudinal axis, the puller plate having a pair of slots therein disposed at an angle to the longitudinal axis; and
a pair of slide pins slidably mounted in the slots of the puller plate and pivotally engaging the blade holders such that longitudinal motion of the puller plate causes the blade holders to pivot about the pivot pin.

Abstract
A powered wire stripper in the form of a precision end stripper includes a housing with a wire-receiving opening at one end. An air cylinder and valve are connected to the housing and arranged to drive the stripper components back and forth. Those components include a pair of blade holders pivotable about a pivot pin between open and closed conditions and slidable within the housing between ready and retract positions. A set of precision cutting blades is mounted on the blade holders in opposing relation. A pair of puller plates are slidable in the housing and include a pair of slots disposed at an angle to the axis of motion. Slide pins slidably mounted in the slots pivotally engage the blade holders such that motion of the puller plate causes the blade holders to pivot about the pivot pin.

11. A powered wire stripper, comprising:
-
a housing including first and second frame members and right and left covers and having at least one wire-receiving opening at one end for receiving wire to be stripped; a cylinder connected to the housing and having a piston movable therein with a piston rod connected to the piston extending from the cylinder to the housing; a valve for supplying pressure fluid to the cylinder on either side of the piston; a pair of blade holders movable between open and closed conditions, the blade holders being slidable in the housing between ready and retract positions; first and second blades mounted in opposing relation on the blade holders and cooperating when the blade holders are closed to cut the insulation of a wire inserted into the wire-receiving opening; actuator means connected to the piston rod for moving the blade holders from one condition to the other when the piston commences motion in one direction and thereafter sliding the blade holders from one position to the other upon continued motion of the piston in that direction; and retention means for positively, releasably retaining the blade holders in said one position until the actuator means has changed the blade holders condition. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)
