Referring to the operation of the present invention configured as described above are as follows.

First, when power is applied to the coil forming apparatus 100 from the outside, the control unit 2 of the coil forming apparatus 100 operates the coil forming unit 1 of the coil forming apparatus 100, thereby forming the coil forming unit. In the part 1, the said annular coil 10 is shape | molded to a desired shape.

Here, when the operating state for molding the shape of the coil 10 in the coil forming part 1 will be described, the fixed forming jig 14 and the movable forming jig 15 of the coil forming part 1 are described. The jig grooves 141 and 151 are inserted into and coupled with the top surface of the fixed molding jig 16 and the movable molding jig 17 to maintain the same surface.

The fixed fixing jig 16 and the movable movable jig 171 are formed at one side of the upper surface of the fixed molding jig 16 and the movable molding jig 17 inserted into the respective jig grooves 141 and 151 of the respective molding jig parts 14 and 15. ) Are formed and positioned so as to be in contact with each other, respectively, and thus the circularly annular coils 10 are formed in the contact state of each of the forming fixing protrusions 161 and the forming movable protrusions 171 as shown in FIGS. 3A and 4A. )

At this time, both ends of the coil 10 that is fitted to each of the molded fixing protrusions 161 and the molded moving protrusions 171, that is, both ends in the free end state, are positioned on the upper surface of the fixed molding jig 16. As each of the positioning grooves 162a of 162 are positioned, the coil 10 is placed in the correct position.

Then, the pneumatic cylinder 18 in the apparatus body 11 is operated to push the movable forming jig unit 15 to the right side of the coil forming apparatus 100 as shown in FIGS. 3b and 4b.
