Abstract

PURPOSE:To keep the feed pitch constant, by expanding and contracting bending parts, which are formed in feed frame parts of materials to be worked, to absorb the variation of the feed pitch generated by molding. CONSTITUTION:In the first process, holes 3 and a pilot hole 4 are provided on a coil material 2. In the second process, the part between holes 3 is subjected to a bending work to form a bent part 5, and unnecessary parts 9 are cut off. In the third process, the flange bending work and the stamping-out of remaining unnecessary parts 9 are performed, and a pilot pin 6 is inserted to the pin hole 4. In the fourth process, the bending work at a negative angle is performed, and therefore, the horizontal feed face is inclined as a prescribed angle, and the bent part 5 is expanded to compensate reduction components of a feed pitch P. In the fifth and the sixth processes, unnecessary parts 9 of the bending molding and feed frames are cut off to obtain final press goods 1.
