ものである。 As shown in FIG. 1, which is a partial cross-sectional view passing through the pole shaft, the lower arm of the automobile wheel support device is inserted into a hole 2a of a cylindrical burring portion 2 at the end of the lower arm 1 made of sheet metal. ball joint 3
A housing 4 that holds a ball 3a is fitted therein. The housing 4 has a stepped portion 4a that fits the inner diameter d of the cylindrical hole 2a of the burring portion, and a stepped portion 4a that fits the inner diameter d of the cylindrical hole 2a of the burring portion.
A stepped portion 4c having a diameter D slightly smaller than the outer diameter D 1 of the cylindrical hole 2a and having a relationship of D 1 >D is provided across the groove 4 b into which the edge 2 b of the cylindrical hole 2 a is narrowed. Therefore, to attach the housing 4 to the cylindrical hole 2b of the burring part, first the housing 4 is pressed until the stepped part 4a is fitted into the cylindrical hole 2a and the stepped part 4c is abutted against the cylindrical hole edge 2b, and then In this case, two presses are required to squeeze the edge 2b into the groove 4b of the housing. In this way, the present invention uses one press instead of two presses to work a mold consisting of an inner die and an outer die in a two-step stroke, and in the first stroke, the housing is pushed into the burring cylinder by the inner die. We have developed a press that can squeeze the cylindrical edge into the housing groove using the outer die during the next stroke.

The inner mold 12 is housed in the vertical hole 13a of the outer mold 13 so that its head 12a can slide up and down over the top 13d of the outer mold 13. An outer mold 13 passes above the inner mold 12 on the lower surface of the frame 10.
There is a horizontal groove 10a in contact with the top 13d, into which a horizontally slidable wedge 15 is fitted.
With this configuration, if the wedge 15 is inserted into the groove 10a up to the top of the inner mold 12, the wedge 15 will hold down the top 12a of the inner mold 12, and the inner mold 12 will be attached to the frame 1.
0 moves with the frame 10 as it descends, and its lower end acts as a mold. At that position, if the wedge 15 is pulled out until it disengages from the top 12a of the inner mold 12, the inner mold 12 will be removed from the frame 12 with its top 12a protruding into the horizontal groove 10a as the frame 10 is lowered. is left behind when descending, and only the outer diameter 13 descends, and its lower end 13
b acts as a type. 14 is a hydraulic cylinder into which the wedge 15 is inserted or pulled out.
