Bending and forming die of reinforcing rib plate

Abstract

The invention discloses a bending and forming die of a reinforcing rib plate. The bending and forming die comprises an upper die part and a lower die part, wherein the upper die part comprises a T-shaped bolt assembly, an upper die base, an inner hexagon screw, a fixing pin and an upper die; the lower die part comprises a bolt, a locating plate, a lower die, a fixing pin, an inner hexagon screw and a lower die base; the T-shaped bolt assembly is positioned in a die base installation hole of the upper die base, the upper die is positioned at the middle part under the upper die base, and four flat surfaces in the upper die are parallel to four flat surfaces of the upper die base; the lower die is positioned at the center part above the lower die base, four flat surfaces in the lower die are parallel to four flat surfaces of the lower die base, the locating plate is positioned at the right upper side of the lower die and is fixedly arranged on the lower die through the bolt, and the right-side flat surface of the lower die is flush with a left-side forming highest point. According to the bending and forming die disclosed by the invention, the structure is simple, the operation is simple and convenient, the manufacturing cost is low, and the production efficiency is high; forming and processing on reinforcing ribs with different materials and different sizes can be realized just by replacing the upper die, the lower die and the locating plate.

Description

technical field [0001] The invention relates to a cold stamping die in the field of mechanical processing, in particular to a bending forming die for a stiffener plate. Background technique [0002] The rib plate is the main part of the car. It is used to strengthen the parts between two parts, which plays a role of stability and reinforcement and increases the safety protection performance. At present, the rib plate is made by hand, that is, the plate cut by wire Put the material into the vise for clamping, and use a hammer to form it manually. Since the material of the part is thick, the part must be heated before it can be manually formed. Therefore, this production method has poor consistency in the processing of the part. The dimensional accuracy cannot meet the technical requirements, the appearance quality is poor, the production efficiency is low, the production cost is high, the material changes after heating, and the safety and usability are poor.
