1) ■The pulley obtained by the device of the present invention is va
The top part is strong and the corners are not thin, so it has good durability. The reason for this is: (1) The manufacturing process of the present invention does not involve any forced processing steps such as forming an annular groove, pushing it outward, and inverting the top or peripheral portion, (2) making the groove top etc. fragile. It never becomes. ■The device of the present invention is composed of two wheels, one of which uses a U-groove forming roller, so there is no need to press with a sharp L-forming roller from the beginning, which is an unreasonable process. For, ■
The top of the groove does not become fragile. ■Spinning molding process in manufacturing pulleys made of sheet metal involves applying pressing force in the axial direction while rotating the cylindrical body, and at the same time applying pressure from a direction perpendicular to the axis using a ``spring drawing roller.''

In order to prevent some of the corners of the molded product from becoming thin, it is necessary to sufficiently apply both of the above-mentioned pressing forces, but in the manufacturing apparatus of the present invention, the axial pressing and the pressing of the "squeezing roller" are performed using separate hydraulic pressures. It is adjustable depending on the device. In addition, the pressure of the "roller for spatula drawing" is not exerted only by the apex of the roller for V-groove forming, for example, but a mold with a flange is used, and the inner surface of the flange is tapered outward. The provision of a stepped roller flange on the V-groove forming roller is effective in preventing a portion of the corner of the molded product from becoming thin. For the reasons mentioned above, the actual V-pulley obtained by the apparatus of the present invention can be produced in which the wall thickness of a part of the corner including the top of the V-groove is completely maintained at 80% or more of the plate thickness.

■As shown in Figure 4, the manufacturing device of the present invention maintains the disk portion (4), spoke portions (5), etc. in stable surface contact with the concave mold at the bottom when pressing from the vertical direction with a “roller for spatula drawing”. The rotation of the lower mold is reliably transmitted to the molded product without slipping, so the V during rotation is reduced.
The dimensional accuracy of the groove runout (R3) is easy to achieve 6. Since the forming device of the present invention uses a U-groove forming roller before the V-groove forming roller, it has good accuracy according to the angle θ of vl. is obtained. ■Since the molding device of the present invention uses a hydraulic device to press the molding rollers, high pressure can be applied by adjusting the pressure, improving overall dimensional accuracy, and ■ flatness of the groove surface. You can also expect ■The forming apparatus of the present invention is designed so that ■the groove forming roller is provided with a stepped roller flange, so that ■the diameter of the groove (
