Abstract

A fusing machine and method employ a first electrode which defines a fusing station and a second electrode which is movable toward and away from the first electrode. Two wires which have been fused together at the fusing station are automatically cut without removing the fused wires from the fusing station prior to cutting them. Also disclosed is an electrode set including a first electrode having an inwardly tapered slot sized and shaped so as to releasably capture wires to be fused and a second electrode having a straight-sided tip sized and shaped so as to be freely movable into and out of the slot in the first electrode.

Claims

1. A fusing machine, comprising:

(a) a base;

(b) a support post extending upwardly from said base;

(c) a lower electrode subassembly mounted on said support post, said lower electrode subassembly including a first electrode which defines a fusing station;

(d) an upper electrode subassembly mounted on said support post above said lower electrode subassembly, said upper electrode subassembly including a second electrode movable toward and away from said first electrode in a direction generally parallel to said support post;

(e) electrode actuator means for moving said second electrode toward said first electrode to engage wires between said electrodes for fusing and moving said second electrode away from said first electrode;

(f) a cutter subassembly including first and second cutting members, said cutter subassembly being mounted on said support post for rotary movement about said support post between a cutting position in which said cutter subassembly is adjacent said fusing station and a non-cutting position in which said cutter subassembly is remote from said fusing station;

(g) lock means for selectively securing said cutter subassembly either in said cutting position or in said non-cutting position; and

(h) cutter actuation means for moving said first and second cutting members relative to one another when said cutter subassembly is in said cutting position to shear wires which have been fused together at said fusing station without removing the fused wires from said fusing station prior to cutting them,

whereby the machine can be operated either to provide both cutting and fusing action with said cutter subassembly in said cutting position or to provide fusing action without cutting action with said cutter subassembly in said non-cutting position.

2. A fusing machine according to claim 1, wherein said lower electrode subassembly is slidably and rotatably mounted on said support post.

3. A fusing machine according to claim 2, wherein said upper electrode subassembly is rotatably mounted on said support post.

4. A fusing machine according to claim 3, wherein said cutter subassembly is slidably mounted on said support post.

5. A fusing machine according to claim 1, wherein said first cutting member includes a notch sized and shaped so as to permit wires to be fused to be inserted laterally into said notch.

6. A fusing machine according to claim 5, wherein said notch terminates inwardly in a generally cylindrical head sized and shaped so as to receive wires to be fused.

7. A fushing machine according to claim 6, wherein said notch includes an inwardly tapered throat extending between an outer edge of said first cutting member and said head of said notch.

8. A fusing machine according to claim 7, wherein said second cutting member reciprocates relative to said first cutting member such that said second cutting member passes back and forth across said notch.

9. A fusing machine according to claim 1, wherein said first electrode includes an inwardly tapered slot having two opposed, inclined sidewalls for releaseably capturing wires to be fused and said second electrode includes a straight-sided tip narrower than said slot, said tip having two oppositely-facing parallel walls, said tip being moved into and out of said slot in said first electrode upon movement of said second electrode towards and away from said first electrode, said parallel walls of said tip confronting said inclined sidewalls of said slot when said tip is received in said slot.

10. A fusing machine according to claim 9, wherein said inclined sidewalls form between them an included angle of about 10°

.

11. A fusing machine according to claim 1, further comprising exhausting means for exhausting fumes from said fusing station.

12. An electrode set, comprising a first electrode including an inwardly tapered slot having two opposed, inclined sidewalls for releasably capturing wires to be fused and a second electrode engageable with said first electrode, said second electrode including a tip narrower than said slot, said tip having two oppositely-facing parallel walls, said tip being engaged in said slot with said parallel walls confronting said sidewalls so that substantial portions of said parallel walls face said inclined sidewalls when said electrodes are engaged with one another.

13. An electrode set according to claim 12, wherein said inclined sidewalls form between them an included angle of about 10°

.

14. A fusing machine comprising:

(a) a first electrode including an inwardly tapered slot having two opposed, inclined sidewalls for releasably capturing wires to be fused;

(b) a second electrode including a tip narrower than said slot, said tip having two oppositely-facing parallel walls; and

(c) electrode actuator means for moving said electrodes towards one another to engage said tip in said slot with said parallel walls confronting said sidewalls so that substantial portions of said parallel walls face said inclined sidewalls.

15. A fusing machine according to claim 14, wherein said inclined sidewalls form between them an included angle of about 10°

.
