Abstract

PURPOSE: To plastically deform the outer corner of the sheet material into the sharp corner, and to manufacture the clutch cover with high effective height of the bend part, by pressing the push die provided with the protuberance to the inner corner of the sheet material formed by the bending work, in order to press the sheet edge.
CONSTITUTION: The punch 16 is inserted into the open mouth of the fitting flange 8 formed in the sheet material for use of the clutch cover 7; the pat 17 is put on the surface adjoining to the outer corner 15 of the bend part, in order to form the chase possessing the sharp corner opposing the outer corner 15. The push die 19, provided with the protuberance 20 possessing the radius of curvature R2, is put on the inner corner of the bend part of the clutch cover 7, and the push die 19 is pressed toward the protuberance 20 in order to press the edge of the fitting flange 8 by the knock-out 18. Hereupon, the plastic flow is caused in the bend part and the inner corner is spread along the surface of the protuberance 20, and at the same time, the outer corner is plastically deformed along the sharp corner formed by the punch 16 and the pat 17.
