FIG. 1 shows a partial perspective view of a clutch retainer 1 manufactured according to the present invention, in which an outward flange 1a is formed on one end side of a cylindrical drum, and teeth 2 are formed on the flange portion. The tooth part 2 is
The cross-sectional shape is almost trapezoidal, and the inner chevron part of the flange 1a is divided into two toothed parts 2a and 2b, and the outer toothed part 2b (that is, the outer peripheral edge side of the flange 1a) is the inner toothed part The cross-sectional shape of the tooth portion is smaller and narrower than that of 2a. The concave portion sandwiched between the two toothed portions 2a and 2b is
This is the groove 3 for the snap spring.

として形成される。 In press forming the clutch retainer 1 having such a structure, the present invention provides an upper die 14 for forming the toothed portion 2a inside the clutch retainer 1, and a toothed portion as shown in FIG. It has a lower die 5 for forming the mountain portion 2b, and a middle die 6 for forming the snap spring groove 3 between the upper die 4 and the lower die 5. A forging device equipped with a plurality of punches 7 is used. This forging device simultaneously forms the tooth portion 2 and the snap spring groove 3, and as shown in FIG.
It is formed as a sheared surface that is sheared by the inward bulge of a and 2b.

方に移動させておく。 When the tooth portion 2 and the snap spring groove 3 are molded simultaneously in this way, the outer peripheral tooth portion 6a of the middle die 6 is fitted into the snap spring groove 3, so it is impossible to take out the clutch retainer 1 after molding. However, in the case of the present invention, the payout can be made easily. That is, the fourth
As shown in the figure, the tooth thickness l 6a of the outer peripheral toothed portion 6a of the middle die 6 is set larger than the tooth thickness l2a of the toothed portion 2a in order to form a predetermined snap spring groove 3. The tooth thickness of the outer peripheral toothed portion 5a of the lower die 5 that forms the valley portion sandwiched between the toothed portions 2b.
l Since it is set smaller than 5a , when the middle die 6 is rotated by half a pitch after molding, the outer peripheral toothed part 6a of the middle die 6 comes off from the snap spring groove 3 and is inserted into the lower die as shown in FIG. 5 to a position overlapping with the outer peripheral gear 5a. Therefore, if the knockout 9 is raised in this state, the clutch retainer 1 can be removed from the upper die 4, the middle die 6, and the lower die 5, and the clutch retainer 1 can be discharged. Note that the punch 7 is moved outward in advance.

ーピン８を下降させると、上記同様の機構により
中部ダイ６を原位置に戻すことができる。 As a means for rotating the middle die 6 by half a pitch, a driver pin 8 having a bent tip can be used as shown in FIG.
The middle die 6 can be moved in the direction of the arrow A by inserting it into the hole 6b formed in the hole 6b and pushing the inclined wall 6c. By appropriately setting this amount of movement, the middle die 6 can be rotated by exactly half a pitch. Conversely, when the driver pin 8 is lowered, the middle die 6 can be returned to its original position by a mechanism similar to the above.

On the contrary, it can also be applied to a case where a punch is placed on the inner surface and a die is placed on the outer surface to form predetermined teeth and a groove for a snap ring on the outer surface. The present invention can be widely applied not only to clutch retainers but also to members having teeth and grooves for snap springs.
