Abstract

PURPOSE:To obtain V-grooved pulleys which have dimensional accuracy by forming an embossed part in the thickness direction at the center of a material and supporting the material by a die using the inside peripheral surface of the embossed part which has a large area against a roller thrust as a bearing part. CONSTITUTION:The embossed part E and a shaft hole H are formed by pressing the center of a flat circular plate material Q. The material Q is held between a receiving die 5a and pressing die 5b pressed by a grooved die 6 to be thickened in the thickness direction. The pressed and thickened material Q is held between dies 8a and 8b and is pressed by a slitting roller 7 to be formed a slitted groove 9. Then, the material Q is held between dies 11a and 11b and a forming roller 10 which has a multi-rib shape is pressed against the slitted groove 9 to form multi-groove S3. The method allows an increased thrust of the roller to manufacture V-grooved pulleys having dimensional accuracy.

Then, while the material Q is rotated together with both dies 5a and 5b, the #scraping roller 6 is pressed against the outer peripheral end surface of the material Q. As a result, the grooved roller 6 also rotates synchronously, and the material Q is compressed in the direction of decreasing its diameter, and at the same time, the material material flowing as the material is compressed in the radial direction increases the thickness in the plate thickness direction. Ru. In this case, the thrust force F of the grooved roller 6 is borne by the rotary receiving die 5a that is in contact with the inner circumferential surface of the shaft hole H and the inner circumferential surface e of the embossed portion I.

Effects of the Invention As shown in F-F, according to the present invention, the inner circumferential surface of the embossed portion protruding in the thickness direction of the material is used as a receiving portion and is supported by a mold to perform molding. The diameter of the embossed part can be made larger than the diameter of the shaft hole. For this reason, the diameter of the embossed part is larger than that of the shaft hole.
The pressure-receiving area of the mold that contacts and supports the inner circumferential surface of the embossed portion becomes larger, and the thrust of the roller can be increased accordingly.
