Abstract
PURPOSE: To manufacture the parts provided with high accurate internal groove, by employing the cylindrical parts for the parts, and by forming the straight guide and the punch angle at the gear of the punch, when the parts provided with internal groove is to be manufactured using the punch and dies.
CONSTITUTION: The cylindrical parts 1 is worked by the punch 4 and dies 3, and the internal gear 101, etc., provided with the internal groove, is manufactured. Hereupon, the employed punch 4 is provided with the straight guide 4B, and the gear 4A including the slope 4C with the punch angle 30W45 degrees continuing to above straight guide 4B. About 0.1mm gap is formed between the outer diameter of the straight guide 4B and the inner diameter of the cylindrical parts 1. Besides, the size of the outer diameter of the straight guide 4B is made slightly larger than the diameter of the tooth bottom 4D of the gear 4A. This punch 4 is pushed into the cylindrical parts 1 placed in the dies 3, and the internal gear 101 provided with high accurate internal groove is formed.
