Abstract

A coil forming apparatus for forming an electrical coil from an electrical wire. The apparatus includes a frame and a spindle assembly coupled to the frame. The spindle assembly includes: a first arm coupled to the frame, wherein the first arm includes a first moveable bracket and a plurality of first moveable spindles coupled to the first moveable bracket and to the electrical wire in a first position. The spindle assembly further includes a second arm coupled to the frame, wherein the second arm has a second moveable bracket that includes a plurality of second moveable spindles coupled to the second moveable bracket and coupled to the electrical wire in the first position. The coil forming apparatus includes a drive system coupled to the first moveable bracket and the second moveable bracket. The drive system is configured to move the first moveable bracket and the second moveable bracket.

Claims

1. A coil forming apparatus for forming an electrical coil from an electrical wire, said apparatus comprising:

a frame;

a spindle assembly coupled to said frame, said spindle assembly comprising;

a first arm coupled to said frame, said first arm comprising a first moveable bracket and a plurality of first moveable spindles coupled to said first moveable bracket and to the electrical wire in a first position; and

a second arm coupled to said frame, said second arm comprising a second moveable bracket comprising a plurality of second moveable spindles coupled to said second moveable bracket and coupled to the electrical wire in said first position; and

a drive system coupled to said first moveable bracket and said second moveable bracket, said drive system configured to;

move said second moveable bracket toward said frame to a second position, said plurality of second moveable spindles of said second arm are configured to form a bend in the electrical wire; and

move said first moveable bracket away from said frame to a third position, said plurality of first moveable spindles of said first arm are configured to form another bend in the electrical wire.

2. The coil forming apparatus of claim 1, wherein said first arm comprises a first stationary bracket coupled to said first moveable bracket and comprises a plurality of first stationary spindles aligned with said plurality of first moveable spindles in said first position and un-aligned with said plurality of first moveable spindles in said third position.

3. The coil forming apparatus of claim 1, wherein said second arm comprises a second stationary bracket coupled to said second moveable bracket and comprises a plurality of second stationary spindles aligned with said plurality of second moveable spindles in said first position and un-aligned with said plurality of second moveable spindles in said second position.

4. The coil forming apparatus of claim 1, further comprising a third arm coupled to said frame, said third arm comprising a third moveable bracket and a plurality of third moveable spindles coupled to said third moveable bracket and to the electrical wire in said first position.

5. The coil forming apparatus of claim 4, wherein said drive system is configured to move said third moveable bracket away from said frame in said third position, said plurality of third moveable spindles are configured to form another bend in the electrical wire.

6. The coil forming apparatus of claim 4, wherein said third arm comprises a third stationary bracket coupled to said third moveable bracket and comprises a plurality of third stationary spindles aligned with said plurality of third moveable spindles in said first position and un-aligned with said plurality of third moveable spindles in said third position.

7. The coil forming apparatus of claim 1, further comprising a fourth arm coupled to said frame, said fourth arm comprising a fourth moveable bracket and a plurality of fourth moveable spindles coupled to said fourth moveable bracket and to the electrical wire in said first position.

8. The coil forming apparatus of claim 7, wherein said drive system is configured to move said fourth moveable bracket toward said frame in said second position, said plurality of fourth moveable spindles are configured to form another bend in the electrical wire.

9. The coil forming apparatus of claim 7, wherein said fourth arm comprises a fourth stationary bracket coupled to said fourth moveable bracket and comprises a plurality of fourth stationary spindles aligned with said plurality of fourth moveable spindles in said first position and un-aligned with said plurality of fourth moveable spindles in said second position.

10. The coil forming apparatus of claim 1, wherein said first moveable bracket comprises a cavity that is configured to receive said plurality of said first moveable spindles in a fourth position.

11. The coil forming apparatus of claim 1, wherein said second arm comprises a second stationary bracket coupled to said second moveable bracket and comprises a plurality of grooves that are configured to receive said second stationary spindles in a fourth position.

12. A method of manufacturing an electrical coil from an electrical wire using an apparatus, the apparatus including a spindle assembly coupled to a frame, the spindle assembly including a first arm and a second arm, each of the first and second arms coupled to the frame, said method comprising:

coupling the electrical wire to a first moveable bracket of the first arm of the spindle assembly, the first moveable bracket positioned in a first position with respect to the frame;

coupling the electrical wire to a second moveable bracket of the second arm of the spindle assembly, the second moveable bracket positioned in the first position with respect to the frame;

moving the second moveable bracket toward the frame to a second position;

coupling a plurality of second moveable spindles of the second moveable bracket to the electrical wire and forming a bend in the electrical wire;

moving the first moveable bracket away from the frame to a third position; and

coupling a plurality of first moveable spindles of the first moveable bracket to the electrical wire and forming another bend in the electrical wire.

13. The method of claim 12, further comprising coupling the electrical wire to a third moveable bracket of the spindle assembly and moving the third moveable bracket to the third position.

14. The method of claim 13, further comprising coupling a plurality of third moveable spindles of the third moveable bracket to the electrical wire and forming another bend in the electrical wire.

15. The method of claim 12, further comprising coupling the electrical wire to a fourth moveable bracket of the spindle assembly and moving the fourth moveable bracket to the second position.

16. The method of claim 15, further comprising coupling a plurality of fourth moveable spindles of the fourth moveable bracket to the electrical wire and forming another bend in the electrical wire.
