Abstract

PURPOSE:To utilize the multistage press-forming process to press-form the middle of a shaft part easily, by using a wedge-shaped split mold die, where projections face to each other in the mold cavity, and a die block having a conical taper face to work a long-sized bolt. CONSTITUTION:Materials formed into goods in outline are press-fitted to a die mold cavity 11a of a split mold die 11 by a two-stage punch 17. After an expand part 4 of materials is fitted into the mold cavity 11a, not only a center base punch 17a presses a flange 2 but also an outside cylinder punch 17b presses a front end face 11b of the die 11, and the die 11 is pressed into a die block 12 together with a movable receiving bed 13 while compressing a spring 15 together with materials. The die 11 is guided by a whirl-stop 16 and is moved along a conical taper face 12b of the die block 12 and has the diameter contracted, and a shaft part 1 of materials pressed from above and below by projections 18 and 18' which face to each other in the depth of the mold cavity 11a and is crushed to a flat shape, and simultaneously, left and right parts of the shaft part 1 are projected to a relief space formed in the mold cavity 11a, thus press-forming a flat recess part.
