Abstract
Apparatus for twisting a wire end comprises a wire holder, a twisting means for selectively engaging the wire end, a drive means operable to rotate the twisting means, and an actuator means operable to move one of the wire holder and the twisting means toward the other to allow the twisting means to engage the wire end. The actuator means is operable to move the one away from the other while the drive means rotates the twisting means, thereby twisting the wire end about its axis.
Claims6
Apparatus for stripping an end of an insulated wire which comprises:
- (a) a horizontal base;
- (b) a wire holder for holding the wire against movement;
- (c) a carriage mounted on said base for horizontal movement along the axis of the insulated wire held by said wire holder;
- (d) a cylindrical member mounted on said carriage for rotation about its axis, the axis of said cylindrical member lying on the axis of the wire held by said wire holder, said cylindrical member containing a wire support element and a stripper blade for cutting through the insulation of the wire end, said support element and said stripper blade being disposed on opposite sides of the axis of the wire held by said wire holder, and said support element and said stripper blade cooperating to hold the severed insulation upon movement of said carriage toward said wire holder;
- (e) drive means mounted on said carriage and operatively connected to said cylindrical member for rotating it about its longitudinal axis;
- and
- (f) actuator means mounted on said base and operatively connected to said carriage for horizontally moving it toward and away from said wire holder, whereby the wire end is stripped of the insulation and twisted as said carriage moves away from said wire holder.
Apparatus for stripping an end of an insulated wire which comprises:
- (a) a horizontal base;
- (b) a wire holder for holding the wire against movement;
- (c) a carriage mounted on said base for horizontal movement along the axis of the insulated wire held by said wire holder;
- (d) a movable block mounted on said base for vertical movement;
- (e) a pair of opposed rollers mounted on said carriage for movement toward each other;
- (f) an upper stripper blade mounted on said movable block;
- (g) first cam means mounted on said movable block for engagement with said opposed rollers to move said rollers toward each other to hold the wire end;
- (h) a lower stripper blade mounted on said carriage;
- (i) second cam means mounted on said movable block for engagement with said lower stripper blade to move it upwardly toward said upper stripper blade when said movable block is moved downwardly;
- (j) first actuator means mounted on said base and operatively connected to said carriage for moving it horizontally toward and away from said wire holder;
- (k) second actuator means mounted on said base and operable to move said movable block vertically;
- and
- (l) drive means mounted on said carriage and operable to rotate said rollers in the same direction;
- (m) whereby upon downward movement of said movable block, said opposed rollers are moved toward each other to grip the wire end, and said upper and lower stripper blades are moved toward each other to cut through the insulation of the wire, the movement of said rollers toward each other and the movement of said upper and lower stripper blades being effected in a coordinated manner.
