Abstract

PURPOSE:To decrease the deformation by a press pressure and to prevent the generation of seizure by increasing the wall thickness and toughness of an outside lower punch at the time of subjecting stepped circular parts to compaction molding by means of the outside and inside lower punches and upper punch. CONSTITUTION:A core rod 6, an inner lower punch 8, the outside lower punch 3 and a guide ring 10 are moved to an up-position so that the top end of the core rod 6, the top end face of the outside lower punch 3 and the top end face of the guide ring 10 are made flush with each other. A powder feed shoe 21 is moved on such surface and the powder P is packed into the space formed in the outside peripheral part of the core rod 6. The upper punch 5 is then moved downward by the pressurizing force of a press mechanism 20 and the stepped circular part is molded by means of the outside lower punch 3 and the inside lower punch 2 (fixed punch 7 and inner punch 8). The thickness of the outside lower punch 3 is increased in this case to increase the rigidity thereof, by which the deformation by the press pressure is decreased and the generation of the seizure is prevented. The good compaction molding is thus executed for a long period of time.

In other words, in the case of a circular part that has stepped portions with different diameters on its outer circumferential surface, in order to make the compressed density of each portion c' of the molded product uniform, a lower punch is inserted corresponding to each stepped portion. is divided into cylindrical shapes, and as the upper punch is compressed, the outer part of the lower punch is moved according to its length, and the powder is filled with the powder before compression and the height of 10 mm is reached after compression. The product height ratio is made to be uniform at each step. In the case of a flange-like stepped part, when the stepped part is thin, the thickness of the punch member at this part is also iI <', where x has a low stiffness,
The compression pressure in the pressing process acts to spread the punch member outward and deform it, so that its outer circumferential portion slides relative to the inner circumferential surface of the outer die in a strong pressure contact state. This press molding I! ! Due to the backlash, sliding creases may occur in the vertical direction on the contact surface between the two, which may eventually lead to burning.

In the above embodiment, since the shape of the step A-1 circular part 1 has a lower surface protrusion 1f in addition to the flange part 1b, the inner lower punch 2 is used to form this protrusion 11'. Although it is made up of a fixed lower punch 7 and an inner lower punch 8, in the case of a shape without the protrusion 1f, the inner lower bump 2 is only formed by the fixed lower punch 7.
If it is composed of 4, it is a good thing. Furthermore, if the number of steps in the component 1 is larger, the number of movable inner [1] 7 punches 8 must be increased in accordance with the number of steps. Furthermore, since the part 1 has a through hole 1C in the center, it requires 2110 rods 6, but in the case of a solid shape, the core rod 6 is not necessary. On the other hand, the formation of uneven shapes such as splines or keys on the inner and outer circumferential surfaces of the component 1 can also be performed by changing the design of each molding surface.
