the lower die is of a cuboid structure corresponding to the upper die, a waist-shaped boss is arranged in the middle of the upper surface of the lower die, a waist-shaped positioning boss is arranged on the waist-shaped boss, and the waist-shaped positioning boss and the waist-shaped boss form a step structure; the size of the outer edge of the waist-shaped positioning boss is the same as that of a waist-shaped hole in the middle of the bracket part; the middle part of the lower die is provided with two pin shaft holes which penetrate through the waist-shaped positioning bosses and the waist-shaped bosses, and the pin shaft holes are respectively arranged corresponding to the two positioning holes in the middle part of the upper die; the two positioning pin shafts are respectively arranged in the corresponding pin shaft holes from bottom to top; the upper end of the positioning pin shaft protrudes out of the waist-shaped positioning boss.
Specifically, the size of the outer edge of the waist-shaped boss is gradually reduced from bottom to top, so that the inclination of the outer edge of the waist-shaped boss is formed, and the demolding of the support part is facilitated.
Specifically, the height of the waist-shaped boss is not less than the height of a flange of a waist-shaped hole in the middle of the support part.
Specifically, the edge of the end part of the waist-shaped groove on the lower surface of the upper die is rounded.
Specifically, the pin shaft hole is a stepped hole; the installation of the pin shaft is convenient.
Adopt technical scheme as above, the utility model discloses the superiority as follows has:
according to the flanging forming die for the chassis support, the positioning pin shaft plays a role in positioning and guiding the upper die, and the positioning is accurate during die pressing; the waist-shaped positioning boss is arranged, so that the bracket part can be accurately positioned before being machined; the edges of the waist-shaped bosses are obliquely arranged, so that the die stripping of the bracket part is facilitated; this patent simple structure, turn-ups shaping is effectual, improves production efficiency.
