薄肉部５によつて、連結されている。 The cup-shaped member as described above is manufactured from a crude product 1 as shown in FIGS. 1 and 2 by finishing processing. Said crude product 1
As shown in the figure, the shaft part 3 is integrally formed at the bottom of the cup part 2, and the cup part 2
Three axial roller grooves 4 are formed at equal angular intervals of 120° on the inner wall of the roller. The outer periphery of these roller grooves 4 is surrounded by a thin wall portion 5, and the thick wall portion 6 where the roller groove 4 is not provided is
They are connected by a thin wall portion 5.

は、ローラ溝４の部分に材料が充分に寄らないた
めに溝部の精度が出ないという不都合があつた。 The arcuate circumferential surface 7 is in rolling contact with a roller supported by a triport shaft, and has a cylindricity,
Considerable accuracy is required in parallelism and allocation of the three roller grooves 4. Conventionally, the roller groove 4 was finished by inserting a full-sized grindstone in the axial direction to polish the arc-shaped circumferential surface 7, or by inserting an inner die into the roller groove 4 and polishing the cup portion 2. There was a method that required ironing, but in the case of a full-form whetstone, the disadvantage was that it took a long time to process and the processing cost was considerably high considering the reduction in the outer diameter of the whetstone. In the case of squeezing, there was a problem that the accuracy of the groove part could not be obtained because the material did not come close enough to the roller groove part 4.

向に押圧する付勢手段とから成つている。 In order to achieve the above object, the constant velocity joint component manufacturing apparatus of the present invention uses a die having an inner shape that is the same as the outer shape of a cup-shaped crude product in which an axial roller groove is formed on the inner wall. , a punch holder which is provided to be movable back and forth in the axial direction within the die and has a shaft portion at the tip; and the shaft portion of the punch holder,
It consists of a punch for ironing the roller groove, which is supported so as to be movable within a certain range in the axial direction and rotatable around the axis, and a biasing means for pressing the punch toward the tip of the shaft portion of the punch holder. There is.
上記の構成によると、成形時におけるパンチと

よび位置度を高める。 According to the above configuration, the misalignment between the punch and the roller groove of the rough product during forming occurs in the axial direction during the insertion operation against the biasing force after the punch contacts the opening edge of the roller groove of the rough product. It is corrected by rotating while moving. Therefore, ironing is always performed with the centers of the punch and the roller groove of the rough product aligned. Further, during ironing, the punch rotates following the roller groove, increasing the contour and position of the roller groove.

の受け座を示す。 The punch 11 is axially movable within a certain range with respect to the punch holder 10, and is biased toward the tip by a spring 13. As shown in FIG. 4, the planar shape of this punch 11 corresponds to the roller groove 4, and the inner diameter of the through hole 14 for inserting the bolt has a margin of 1 to 2 mm with respect to the outer diameter of the bolt 12. The structure is such that the holding punch 11 can be moved laterally. Further, the radius of the outer diameter portion 15 of the punch 11 is set to be approximately 0.5 mm smaller than the radius of the inner wall of the thin wall portion 5 of the crude product 1. Furthermore, the ironing surface 16 that contacts the arcuate peripheral surface 7 of the roller groove 4 has a predetermined spherical shape.
A flank surface 17 is formed which is sufficiently smaller than the inner diameter of. Reference numeral 18 in FIG. 5 indicates a receiving seat for receiving the spring 13.

This is attached to the upper ram 19 in the assembled state.
Further, the crude product 1 is set in the die 8 in a state in which it is in phase with the punch 11. Punch 11 from now on
When the punch 11 is lowered, the punch 11 follows the roller groove 4 formed in the previous step and squeezes the arcuate circumferential surface 7. At this time, the outer periphery of the assembled product 1 is restricted from moving outward by the inner periphery of the punch 11, so that it can be squeezed with high precision.

型交換が容易となり、型コストの低減が図れる。 As described above, according to the present invention, the punch is supported so as to be movable within a certain range in the axial direction and rotatable around the axis, and is also biased toward the tip of the shaft, so that the rough product is not easily formed during molding. Since the punch can easily follow the roller groove and settering is performed reliably, it is possible to finish the roller groove with high precision. Further, during the ironing process, the punch rotates following the roller groove, so the contour and positional accuracy of the roller groove can be improved. Furthermore, since the punch is supported by the shaft of the punch holder,
Mold replacement becomes easy and mold cost can be reduced.
