PURPOSE:To make thickness in a thick part shift from the circumference of a pressing groove to that of a cross groove and secure ample movements of the thickness as well as to make the sharp and smooth cross groove formable, by forming a local pressing groove in position along the cross groove on an inner circumferential surface of an outer circumferential surface of an outer ring. CONSTITUTION:A blank form material is put on a mandrel punch 12 and then a movable cope 14 is made to go down. the circumference of an outer ring part 4 of the blank form material 13 is restrained by a forming mold 29 by means of operation of a taper surface 32 of a passive mold 30 being pressed by a draw-back mold 33. An inner surface of the outer ring part 4 of the blank form material 13 is pressed by a cross groove mold 16 and a pressing groove mold 16', forming a cross groove 1. At this time, or when the local pressing groove mold 16' forms the cross groove 16, thickness in a thick part of the blank form material 13 is shifted.

Alternatively, in order to further improve productivity, there is a method using retroactive processing using a mold (Japanese Patent Application Laid-Open No. 58-50147

However, in retroactive processing using this mold, a phenomenon may occur in which the cross grooves 1 are not formed sharply and smoothly, as shown in FIGS. 6 and 7. This phenomenon is called "dare." That is, the internal curved surface of the cross groove 1 must be formed to correspond to the curvature of the spherical surface of the ball 5, and in consideration of the smooth movement of the ball 5, the cross groove 1 must be formed sharply and clearly. Otherwise, the durability of the universal joint will be reduced. However, 1. If the pressing force of the mold during retroworking is insufficient, the cross groove 1 may not be formed sharply and smoothly as shown by the chain line in FIG. This "sloping" was particularly problematic at the edge portion of the cloth #1. The cause of this "sag" is thought to be that the movement of the thick portion of the wall that moves in the circumferential direction is insufficient due to insufficient pressing force.

Conventionally, in order to prevent this "sag", it was necessary to increase the pressing force of the mold, which required a high-output press device and increased equipment costs. Furthermore, when suppressing the outer ring 4
The load generated on the outer ring increases, making it more susceptible to cracking, increasing residual stress, and even deforming the mold, which deteriorates the dimensional accuracy of the cross groove of the manufactured outer ring.

4m is appropriate. The groove may be a local pressing groove having a constant width in the axial direction. Therefore, the local suppression groove 7 and the cross groove l
The width W of the local pressing groove 70 becomes smaller where the distance is narrower, and becomes wider where it is wider. The cross groove 1 and the local suppression groove 7 are simultaneously molded using a mold as described later. This formation will be explained in detail with reference to FIGS. 8 and 9.

After the cross groove mold 16 is removed from the molded product 13, the mandrel punch 12 is moved downward by the cylinder 36 via the rod 37 and removed from the pressing groove mold 16'. At the same time, the pressing groove mold 16' is moved toward the υ inner position by the spring 35 and reaches a position where the false molded product 13 is removed. At this time, the position is determined by the pin 34.

The inserted "mushroom"-shaped central shaft 19 is connected to a cylinder 20 attached to the fixed lower mold 11. When this cylinder 20 is driven by a hydraulic unit (not shown), the knockout 18 moves up and down in the axial direction. On the other hand, a presser die 15 is supported by the movable upper die 14. This support is achieved by inserting the rear part of the presser foot ff115 into a presser mold chamber 22 formed vertically in the center of the movable upper mold 14 via a packing 23. The holding mold chamber 22 is filled with a press, and molding is performed by applying pressure to the press oil above the holding mold 15. Note that inside the lower end of the presser die 15 there is a shaft portion 4 of the material 13.
A recess 24 corresponding to the presser mold 1 is formed.
At 5, above this recess 24, a blowing bar 25 is pressed downward by a spring 26.

Next, near the periphery of the mandrel punch 12, there is a pressing groove mold 16 for determining the ascending position of the mandrel punch 12.
There is a mandrel punch holding die 27 for guiding the die, and a slide plate 28 is provided around the mandrel punch holding die 27. The mandrel presser mold 27 and the slide plate 28 have upper surfaces of the same height. On this upper surface, as shown in FIG. 8, six molds M29 are arranged in contact with the periphery of the formed material 13, and furthermore, a passive mold 30 is arranged around the mold 30 fixed to the mold 29. ing. This passive mold 29 is drawn outward via a rod 31 by a spring or cylinder (not shown) provided on the fixed lower mold 11. At the same time, a taper 1111732 is formed on the back surface of the passive mold 30, and as the movable upper mold 14 descends, the taper surface 32 is pressed by the valley mold 33 provided on the movable upper mold 14 and brought to the center.

The operation of this embodiment will be explained below. The material 13 is placed on the mandrel punch 12, and the movable upper mold 14 is lowered. The periphery of the outer ring portion 4 of the raw material 13 is restrained by the mold 29 by the action of the tapered surface 32 of the passive mold 30 which is suppressed by the valley mold 33. The upper part of the raw material 13 is pressed by a presser die 15. The pressing force of the presser foot ff115 at this time becomes constant because the oil pressure in the presser die chamber 22 is adjusted to a constant value. The inner surface of the outer ring portion 4 of the raw material 13 is pressed by the cross groove die 16 and the pressing groove die 16' to form a cross@1. At this time, as shown in FIG. 10, when the local pressing groove die 16' forms the pressing groove 16, the thick portion of the formed material 13 is moved. Therefore, when the cross groove 1 is formed by the cross groove mold 16, a sufficient amount of movement of the meat is ensured. Therefore, sharp and smooth loss grooves can be formed without causing droop as in the conventional method.

In the outer ring according to the above embodiments, the wall thickness of the outer ring 4 is thinner in the region where the cross groove is formed. Further, the local pressing groove 7 was formed on the inner circumferential surface. However, in other embodiments, as shown in FIGS. 3 and 4, the present invention can also be applied to an outer ring 4 whose wall thickness is approximately the same along the entire circumference, and furthermore, the present invention can be applied to an outer ring 4 having substantially the same wall thickness along the entire circumference. Groove 7
can also be formed on the outer peripheral surface of the outer ring. That is, local pressing grooves 7 are formed on the outer circumferential surface of the inner circumferential surface of the outer ring 4 corresponding to the edge portion of the cloth vinegar 1. When this local pressing groove 7 is formed, the meat of the thick portion moves from the outer circumferential surface toward the inner circumferential surface, so that sufficient meat can be supplied to the edge portion of the cross groove l. Therefore, it is possible to form a sharp and smooth loss groove l, and it is possible to prevent the conventional "sag" from occurring.
