Description of the Related Art In an electric motor, a stator for generating a rotating magnetic field is composed of a primary winding and a core having teeth serving as magnetic poles by passing a current through the primary winding. The shape of this core is such that slots for accommodating the magnetic poles and the primary windings are alternately arranged in the circumferential direction on the inner circumference of the cylinder. In the conventional manufacturing method of this stator core, thin steel plates each having a cross section orthogonal to the cylindrical axis of this stator core are laminated in the cylindrical axis direction. The laminated thin steel plates have a substantially annular shape, and are formed by punching a steel plate material.

That is, when the strip-shaped material is wound, the amount of expansion or contraction differs in the width direction of the strip-shaped material, and this difference may cause wrinkles near the inner circumference and cracks near the outer circumference. When wrinkles are generated, there is a problem that a gap is formed between the laminated strip-shaped members, which causes an increase in magnetic resistance. Even when a crack is generated, there is a problem that the magnetic resistance is increased, the band-shaped material is broken, and the winding itself becomes impossible. Further, when the pins are stacked a predetermined number of times, the pins that regulate the slot position are sequentially pulled out, so there is no one that regulates the slot position after that, and there is a problem in that the position shifts.

される。In FIG. 1, a belt-shaped material 10 is a winding jig 12.
The state of being wound up is shown. The strip-shaped material 10 has comb teeth 16 arranged on one side of the base portion 14 at an equal pitch. After being wound and laminated, the comb teeth 16 form magnetic poles of the stator core, and the comb teeth and the comb teeth are formed. The portion between forms a slot. The band-shaped material 10 is linear before passing through the die 18, and after passing through the die 18, is curved with a predetermined curvature in a plane formed by the plate of the band-shaped material as shown in the figure.

考慮して修正が施されている。As shown in FIG. 2, the die 18 includes two rollers 20 and 22 which sandwich the belt-shaped material 10, and these rollers 20 and 22 have a substantially truncated cone shape. The base 14 of the strip 10 is sandwiched between these two rollers 20 and 22, and pressure is applied in the plate thickness direction of the strip. By this pressurization,
The strip material 10 extends in the longitudinal direction. Then, as described above, since the rollers 20 and 22 have a substantially truncated cone shape, one of the base portions 14 of the strip-shaped material is further pressed and further stretched. Since the band-shaped material 10 is wound with the comb teeth 16 inside,
It is necessary to further extend the end portion on the side opposite to the end on which the rollers are provided, and the apparatus of this embodiment is also arranged so that the large diameter side of the rollers 20 and 22 presses this portion. Therefore, the outer peripheral side when the strip-shaped material 10 is wound is further extended,
The linear strip 10 is bent. Note that the rollers 20 and 22 may be shaped in such a manner that, if the belt-shaped material 10 extends only in the longitudinal direction, the rolling is performed in proportion to the radius of curvature when wound, and thus, if it is a simple truncated cone shape. good. However, the correction is actually made in consideration of the elongation of the strip 10 in the width direction.

る。The band-shaped material 10 thus bent is wound around the winding jig 12. As shown in FIGS. 1 and 3, the winding jig 12 includes an outer cylinder 24 and an inner cylinder 26.
A drive shaft 28 that rotates the winding jig 12 is fixed to the inner cylinder 26. The outer cylinder 24 is divided into four in the circumferential direction, and the outer cylinder 24 is circumferentially positioned by the key 30 on the outer circumference of the inner cylinder 26. Each of the four divided outer cylinders 24 is arranged with a slight gap as shown in FIG. Further, on the outer circumference of the outer cylinder 24, there is a ridge 32 having a substantially semicircular cross section over the entire length of the cylindrical portion in parallel with the cylindrical axis. The ridges 32 are provided in the same number as the teeth of the stator core. And this ridge 32
Enters between the comb teeth 16 of the wound strip 10 and positions the comb teeth 16 in the circumferential direction. Further, a flange portion 34 is provided at one end of the outer cylinder 24, and the band-shaped material 10 is wound and laminated in order from the end portion provided with the flange portion 34.

6 and 38 are provided, and taper portions 40 and 42 are also provided at positions where the inner cylinder abuts on these taper portions 36 and 38. With these tapered portions, the outer cylinder 24 is positioned in the radial direction by the inner cylinder 26, and resists the tightening force generated when the strip 10 is wound.

Therefore, the amount of elongation increases toward the outer side, and it is possible to prevent wrinkles and cracks from occurring in the band-shaped material 10 when wound.

At this time, the protrusions 32 provided on the outer periphery of the winding jig 12 mesh with the comb teeth 16 to prevent the comb teeth 16 from being displaced. When the strip-shaped material 10 is wound a predetermined number of times, it is axially pressed by the pressing jig 44 and is sandwiched between the strip-shaped material 10 and the brim portion 34. In this state, a predetermined portion on the outer circumference of the strip 10 is welded. Finally, the inner cylinder 26 is pulled out, the outer cylinder 24 loses its inner support, and is removed from the wound strip 10 or the stator core.
