り、その将来性が宿望されている。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of manufacturing a poly-V pulley.
A poly-V pulley with multiple wavy grooves has a single V
Since the contact area of the V-belt is wider than that of the groove pulley, the rotational transmission force is extremely superior. Therefore, the height of the V-groove can be reduced, and the diameter and distance between the pulleys can be reduced, making it possible to reduce the size and weight. Furthermore, it has several advantages, such as the ability to interpose a number of pulleys between the multi-threaded V-belts stretched between the pulleys and drive them simultaneously, and its future prospects are promising.

チ間隔が不揃いになるという欠点があつた。 As a prior art related to a method for manufacturing a poly V pulley, the circumferential wall of the cup-shaped material is preformed on the outer surface side using a preforming roller into a corrugated cross-sectional shape having a plurality of troughs, and then the circumferential wall of the cup-shaped material is This is a method in which the material is compressed in the axial direction and formed into a predetermined poly V groove by rolling with a rotary forming roller, and a waveform is formed in preliminary forming. However, even though the distance between the polygon grooves is narrow, it is necessary to use thicker material to provide strength.
Processing material during roller forming is unstable (final pitch
3.56), the important drawback was that the pitch spacing was uneven.

つている。 Further, as a prior art, there is also Japanese Patent Publication No. 11817/1983. This is a method that requires the steps of forming a sinusoidal shape, a step of forming a meandering shape, and a step of forming a poly V groove.The material is made thicker and the inner surface of the peripheral wall is finally formed to be flat. be. However, the disadvantage of this method is that the processing steps are complicated.

刻設される。 1 in Fig. 1 is a cup-shaped material formed in advance by press working, arrow R 1 indicates rotating the cup-shaped material, and 2 is a scraping roller in the direction of arrow F 1 . Although not shown in the drawings, the cup-shaped material is pressed forward by the upper male die, but at this time the outer surface of the cup-shaped disk portion 1a is fitted into the lower female mold, and the inner surface is pressed to the extent that the upper male mold does not compress it. Rotate with the bottom fully pressed. The circumferential wall portion 1b of the cup-shaped material is cylindrical with no poly grooves formed yet, so it has a considerable height, and the intervals between the protruding rings 2a on the surface of the scraping roller 2 are wide. . Projection ring 2a...2
A looks like a ring with many sharp edges protruding from it, like the tip of a nail. Therefore, when it is pushed into the outer surface of the cup-shaped peripheral wall portion 1b, slot-shaped poly grooves 3 are carved on the outer surface of the peripheral wall portion 1b.

が本発明の方法の第１工程である。 At this time, the part carved with the slotted poly groove 3...3 will be slightly thinner, but it is still within a range that does not pose any problem in terms of strength, and On the outer surface of the upper and lower circumferential walls of each polygon groove 3, outwardly bulging portions 3a and 3b are formed as shown in FIG. The above is the first step of the method of the present invention.

に、しかも両型ともテーパーが設けられている。 Figure 3 shows that the material 4 after the first step obtained in this way is pressed in the axial directions A 1 and A 2 with an upper male die 5 and a lower female die 6 to make poly V grooves protrude. It is compressed in order to make the wall thicker for use, and it is also characterized by the fact that the pitch of the suriwari is reduced to the pitch of the finished product. In other words, if the height is too high for the wall thickness, it will inevitably curve during compression, or it will be a split pitch to obtain a predetermined wall thickness, so the distance between 2a and 2a is 11-
It only becomes 11 without collapsing and becomes P 1 → P 2 .
The outer surface of the circumferential wall is compressed into a corrugated shape 7, while the inner surface of the circumferential wall is compressed into a flat 8, which is the second step of the method according to the invention. Of course, the male type 5 is smaller and the female type 6 is larger, and both types are tapered.

At this time, although not shown, the material 9 is gripped from above and below to the extent that it is not compressed in the same manner as in the first step, and is rotated as described above. The mold has a narrow pressure on the mounting surface, and the groove is held in the upper and lower molds with a predetermined dimension. The outer surface of the peripheral wall of the material 9 has a wavy shape similar to the poly V protrusion shape 10a of the poly groove forming roller 10.
