ていた。第８図はその製品５を平面図である。 Fig. 7 shows a conventional method of integrally forming a product by plastic working. After annealing and lubricating the columnar material 1 shown in Fig. 7a, forward extrusion processing is performed to form the product as shown in Fig. 7b. An intermediate product 2 having a shaft portion 2a as shown is molded. Next, the head 2b is hit with a hedging tool to expand the outer diameter of the material into a disk shape as shown in FIG. After that, this is subjected to cold backward extrusion processing to form a cup-shaped main body part 4a, and an intermediate molded product that closely resembles a product having a main body part 4a and a shaft part 4b as shown in FIG. Set it to 4. Subsequently, in order to improve the precision of the inner diameter portion 5c of the main body portion 4a, finishing molding is normally performed to obtain the product 5 shown in FIG. 7e. FIG. 8 is a plan view of the product 5.

ークの長いプレス機が必要となり、そしてプレス
機のノツクアウト仕様は前方押出しにより成形さ

は、プレス機による前方押出し加工は無理とな
る。 However, in the conventional forming method as described above, a forward extrusion process is required to form the shaft, a press machine with a relatively long knock-out stroke is required, and the knock-out specifications of the press machine are is determined by the shaft portion formed by forward extrusion, and if the shaft portion is particularly long, forward extrusion processing using a press machine is impossible.

の分製品成形エネルギーが増大し、生産性も低
く、コスト高となる問題があつた。 Furthermore, intermediate annealing and lubrication treatment are essential prior to the backward extrusion process when forming the cup-shaped main body, and the cost of these treatments accounts for a relatively large proportion of the total processing cost of the product by forging. Furthermore, since it is necessary to perform a hedging process on the intermediate product after forward extrusion of the material, a special press machine is required for this purpose, and the energy required to form the product increases accordingly, resulting in low productivity and high costs. There was a serious problem.

とし、コスト高となる問題がある。 Furthermore, conventional methods for shaping and joining the cup-shaped main body and shaft separately employ brazing, bolting, or plastic engagement through local material deformation; However, after the molding process, a joining process of the parts is required, and additional processing and high processing accuracy are required between the parts to be joined, resulting in high costs.

(1) まず、第１図ａに示すように成形品の形状に
要求されるカツプ状の本体部用素材１０及び軸

Figure 1b is formed by forging by applying 0 to a press machine.
As shown in the figure, there is a hole 1 into which one end of the shaft material 11 can fit.
0a is formed at the center of the end surface of the main body portion material 10.

During this backward extrusion process, the fitting end portion 11 1 of the shaft material 11 is expanded and expanded in the circumferential direction as shown in FIG. Subsequently, the shafted outer ring of the constant velocity universal joint is subjected to finishing molding (not shown) in order to improve the precision of the inner diameter portion 12c of the main body portion 12.

間が完全に消失し、両者の結合は完全となる。 Figures 2a and 2b are for explaining the state of deformation of the tissue at the bottom of the cup-shaped main body 12. If we consider the case where a lattice-like pattern as shown in Fig. 2a is drawn, the lattice-like pattern after backward extrusion becomes as shown in Fig. 2b, and the deformation of the pattern is caused by the cup-shaped main body. 1
The bottom part 12a of 2 and the rising part 1 connected thereto
It becomes large at 2b. This means that the expansion flow deformation of the tip of the shaft material 11 fitted into the hole 10a of the cup-shaped main body material 10 is increasing, and at the same time, the cup-shaped main body 12 after molding is The strength of the connection between the shaft portion 13 and the shaft portion 13 is increased.
In addition, since precision between the hole and the shaft is not required, for example, even if there is a gap between the two members, the gap will completely disappear due to the molding pressure during molding of the inner diameter part 12c of the cup-shaped main body 12, and the gap will disappear between the two members. The bond is complete.

Since the extrusion method is used, the length of knockout operation required of the molding press is reduced, which is particularly advantageous during automatic conveyance. In addition, the conventional hedging process for forming an intermediate product is no longer necessary, and cup forming can be performed without re-annealing, which reduces the number of forming processes.
Productivity can be increased and product costs can be reduced.
