The shaping process includes rounding, roundness correction and the like.

[0035] The driving gear 8 is engaged with one of the driven gears 9 to drive all the driven gears 9 to rotate, thereby driving all the torsion wire chucks 3 to rotate. The present application can realize the twisting of the wires by rotating all the torsion wire chucks 3 through one driving motor and one driving gear 8.

[0036] Each of the twist wire chuck 3 is provided with a clamping groove 31 for clamping the wire end on the block line cake, so that the two wire ends on the same diamond-shaped coil pass into the twist wire chuck 3 from the clamping groove 31, so that the two wire ends are twisted together to form a wire end when the twist wire chuck 3 rotates. The wire end can be inserted into the clamping groove 31 with a larger depth, and the twist wire chuck 3 rotates at a lower speed. Since the wire end is an enameled wire, it has a certain hardness, so that after the wire end enters the clamping groove 31, it is not easy to fall out of the clamping groove 31 when the twist wire chuck 3 rotates. In order to automatically insert the wire end into the clamping groove 31 at the corresponding position, the twist wire module further comprises a wire end pressing device, and the wire end pressing device is arranged on the support seat for pressing the wire end of each diamond-shaped coil into the clamping groove 31 at the corresponding position.
