Abstract

PURPOSE:To prevent the corner part from becoming a projection shape and to improve the quality of external appearance by working the flange part by bending the side edge inward after performing stepping work of corner part at an intersection part of walls of car body members. CONSTITUTION:A flat plate material is formed to a work W by drawing in which the first wall (a) is intersected by the second wall (b). Then, in trimming, the work W is set on a die 1 having a cutting edge 1a, a punch bed 2 is lowered and pressed and held by a presser hung through a spring 3, and at the same time, scraps (j) are removed by a cutting edge 5a and a cutting edge 1a of a punch 5 fixed to the punch bed 2. At this time, a recessed part 1b and a projected part 4a for stepping work are formed at positions corresponding to the die 1 and the stepped part (i) of the presser 4, and the stepped part (i) is worked. Then, in a flange working process, the stepped work W is set on a die 11 of a similar device, and pressed and held by a presser 12, and the side edge of wall parts (a), (b) are bent simultaneously by a punch 13, and the flange parts (c), (d) are worked.
