る。Incidentally, in the toothed ring 1, it is desirable that the height h of the convex teeth 6 from the surface of the concave portion be as high as possible from the viewpoint of the rotation detection accuracy. However, in the case of the convex tooth forming method based on semi-shearing in which shearing is stopped near the middle of the material thickness t, the height h of the convex teeth 6 is limited to a range smaller than the material thickness t and cannot be so high. In particular, when the thickness t of the material is reduced to reduce the weight, the height h of the convex teeth 6 is further reduced, which is more disadvantageous for rotation detection.

The cylindrical portion 3 and the flange portion 4 are formed by the above-described burring process. The flange portion 4 is formed into a concavo-convex shape by a shearing process described later. In particular, a plurality of convex teeth 6 are provided at regular intervals in the circumferential direction on the surface side (upper side) of the flange portion 4. As shown in FIG. 2, a concave portion 7 is provided between each convex tooth 6, and the convex tooth 6 protrudes from the surface of the concave portion 7 by a predetermined height H.

In this case, as shown in FIG. 1, a pair of upper and lower concave and convex molds is used. The upper die 8 is an elevating type, and the lower die 9 is a fixed type. Protrusions 8a, 9a and recesses 8b, 9b are alternately provided along the circumferential direction on each of the molds 8, 9, and the protrusions 8a (9a) of one mold 8 (9) are replaced with the other mold 9 (8).

Reference numerals 0a and 10b have a rounded cross section having predetermined radiuses Ra and Rb. Further, in the upper die 8, a corner 11a formed by the top surface of the concave portion 8b and the side surface of the convex portion 8a has a minute radius shape whose cross section is substantially angular. This is to sharpen the corner edges of the convex teeth 6 as shown in FIG. On the other hand, as shown in FIG. 2, the vicinity of the bottom of the concave portion 9b in the lower die 9 does not participate in the molding. For this reason, the corner of the bottom of the concave portion 9b is formed into a natural round shape by shaving and polishing, or electrical discharge machining and polishing.

The concave portion 9b of the lower mold 9 has a greater depth in the height direction than the concave portion 8b. This is to allow the material to escape in the concave portion 9b of the lower die 9 as shown in FIG.

The upper die 8 is raised, and the flange 4 is placed on the projection 9 a of the lower die 9. The flange portion 4 is set with the surface side, which is the side for processing the convex teeth, facing upward. Next, in this state, the upper die 8 is lowered, the flange portion 4 is sandwiched between the upper die 8 and the lower die 9 from the front and back sides, and after being subjected to shearing processing, press forming is performed. As shown in FIG. 2, when the upper mold 8 descends, the tip of the projection 8 a of the upper mold 8 is
Until it slightly enters the recess 9b. By doing so, the tip of the convex portion 9a of the lower die 9 slightly comes into the concave portion 8b of the upper die 8 naturally. In other words, the projections 8 of the two dies 8, 9
a and 9a slightly overlap each other in the height direction.

部７の下面は下にダレた形状となる。The projection 9a of the lower mold 9 positively pushes the material of the flange 4 into the recess 8b of the upper mold 8. As a result, the material is pressed and formed in the concave portion 8b, and the convex teeth 6 having a square cross section along the inner surface shape of the concave portion 8b are completed. On the other hand, upper die 8
Presses the material between the convex teeth 6 into the concave portion 9b of the lower die 9. Thereby, the concave portion 7 of the flange portion 4 is formed. The surface 13 and both side surfaces 14 of the concave portion 7 are formed into a flat surface by the lower surface of the upper mold protrusion 8a and the side surface of the lower mold protrusion 9a. On the other hand, since the material is released downward during the formation of the concave portion 7, the lower surface of the concave portion 7 has a downwardly sagged shape.

Stretched in the height direction. The stretched material 12 maintains the connection between the convex teeth 6 and the concave portions 7, and the entire convex teeth 6 are located above the concave surface 13. Convex teeth 6

なる。In this toothed ring 1, the height H of the convex teeth 6 from the concave surface 13 is larger than the thickness T of the convex teeth 6. In other words, the protruding teeth 6 can be made higher by the amount by which the material 12 is stretched in the height direction. As a result, the height of the convex teeth can be increased as compared with the conventional half shearing case, which is advantageous for rotation detection. In addition, the material thickness T 0 (see FIG. 1) can be made thinner to the extent that the convex teeth 6 can be made higher, which is advantageous for weight reduction. Convex teeth 6 and concave parts 7
Are connected by the material 12, so that the rigidity of the entire ring is ensured. The material 12 connects the corners on both sides of the bottom of the convex teeth 6 and the corners on both sides of the upper end of the recess 7. Material 1
2 is formed by the rounded corners 10a and 10b, so that the convex teeth 6 and the concave portions 7 are smoothly connected, which is advantageous in strength.

The convex teeth 6 and the concave parts 7 are connected by utilizing the plastic elongation of the material at this time, and the convex teeth 6 are positioned above the concave parts 7.

It is usually slightly thicker.

Here, the top surface 15 of the projection 9a bulges in a rounded cross section. In this case, the height H of the convex teeth 6 is further increased in relation to the minimum thickness Tmin of the convex teeth 6, and a further reduction in the material thickness can be expected.
