Abstract

A wire processing apparatus comprises a frame, a clamping device mounted on the frame and adapted to clamp a wire to be processed, and a straightening and cutting device mounted on the frame. The straightening and cutting device is adapted to press a conductor of the wire into a straight shape and cut the conductor to a predetermined length after pressing.

First claim

What is claimed is:

1. A wire processing apparatus, comprising:
a frame;
a clamping device mounted on the frame and adapted to clamp a wire to be processed; and
a straightening and cutting device mounted on the frame and adapted to press a conductor of the wire into a straight shape and cut the conductor to a predetermined length after pressing, comprising:
a straightening die including an upper straightening module and a lower straightening module facing the upper straightening module;
a cutting tool including an upper cutting blade and a lower cutting blade facing the upper cutting blade;
a sliding block slidably mounted on the frame; and
a driving mechanism adapted to drive the sliding block, the upper straightening module and the upper cutting blade are mounted on the sliding block and are movable upward and downward in a vertical direction with the sliding block, the lower straightening module and the lower cutting blade are fixedly mounted on the frame.

2. The wire processing apparatus of claim 1 , wherein the upper cutting blade and the lower cutting blade are offset from each other by a predetermined distance in a horizontal direction and the upper cutting blade does not contact the lower cutting blade during cutting the conductor.

3. The wire processing apparatus of claim 2 , wherein the predetermined distance is within a range of 1/20 to ⅕ of a diameter of the conductor.

4. The wire processing apparatus of claim 3 , wherein the predetermined distance is equal to 1/10 of the diameter of the conductor.

5. The wire processing apparatus of claim 1 , wherein the upper straightening module is movably mounted in a receiving chamber formed in the sliding block and a spring is provided in the receiving chamber to push the upper straightening module downward in the vertical direction.

6. The wire processing apparatus of claim 5 , wherein, after the upper straightening module is moved downward in the vertical direction and is brought into contact with the conductor, the spring is gradually compressed to exert a downward push force in the vertical direction to the upper straightening module to press the conductor located between the upper straightening module and the lower straightening module into the straight shape.

7. The wire processing apparatus of claim 6 , wherein, before the conductor is pressed into the straight shape by the upper straightening module and the lower straightening module, the upper cutting blade is not in contact with the conductor.

8. The wire processing apparatus of claim 7 , wherein, after the conductor is pressed into the straight shape by the upper straightening module and the lower straightening module, the upper cutting blade moves into contact with the conductor and cuts the conductor by cooperating with the lower cutting blade.

9. The wire processing apparatus of claim 8 , wherein the driving mechanism includes an air cylinder adapted to drive the sliding block.

10. The wire processing apparatus of claim 9 , further comprising a reset spring provided on the frame and adapted to push the sliding block upward in the vertical direction so that the sliding block is automatically moved up to an initial position.

11. The wire processing apparatus of claim 1 , wherein the clamping device includes a fixation base on which a positioning slot adapted to position the wire is formed and a pressing mechanism provided on the fixation base and adapted to press the wire in the positioning slot.

12. A wire processing apparatus, comprising:
a frame;
a clamping device mounted on the frame and adapted to clamp a wire to be processed; and
a straightening and cutting device mounted on the frame and adapted to press a conductor of the wire into a straight shape and cut the conductor to a predetermined length after pressing, comprising:
a straightening die including a first straightening module;
a cutting tool including a first cutting blade;
a sliding block slidably mounted on the frame; and
a driving mechanism adapted to drive the sliding block, the first straightening module and the first cutting blade are mounted on the sliding block and are movable upward and downward in a vertical direction with the sliding block.

13. The wire processing apparatus of claim 12 , further comprising a waste collecting device adapted to collect a waste material cut off from the conductor.

14. The wire processing apparatus of claim 13 , wherein the waste collecting device comprises:
an air blowing device including an air blow pipe fixed on the frame and configured to blow off the waste material that is adhered to the cutting tool; and
a vacuum suction device including a vacuum suction pipe fixed on the frame and configured to suck the waste material blown off from the cutting tool into a waste container of the vacuum suction device.

15. The wire processing apparatus of claim 14 , wherein an outlet of the air blow pipe is located near the first cutting blade.

16. The wire processing apparatus of claim 15 , wherein a suction inlet of the vacuum suction pipe is located near a second cutting blade facing the first cutting blade.

17. The wire processing apparatus of claim 12 , wherein the frame is detachably mounted on a seat.

18. The wire processing apparatus of claim 17 , wherein a plurality of positioning pins are disposed on a bottom of the frame and are adapted to be mated with a plurality of positioning holes of the seat to detachably mount the frame on the seat.

19. The wire processing apparatus of claim 12 , wherein the first straightening module is movably mounted in a receiving chamber formed in the sliding block and a spring is provided in the receiving chamber to push the first straightening module downward in the vertical direction.

20. The wire processing apparatus of claim 19 , wherein:
after the first straightening module is moved downward in the vertical direction and is brought into contact with the conductor, the spring is gradually compressed to exert a downward push force in the vertical direction to the first straightening module to press the conductor into the straight shape, and
after the conductor is pressed into the straight shape, the first cutting blade moves into contact with the conductor and cuts the conductor.
