Abstract

The invention discloses an automobile brake shoe wing plate bending die which comprises an upper die and a lower die. The lower die mainly comprises a guide pillar, a positioning plate, a lower die plate, a positioning pin, a fixing plate, a female die ejector block, a female die left part and a female die right part; and the upper die mainly comprises a guide sleeve, an upper die plate and a male die. The bending die adopts design of an upper and lower die structure; a U-shaped section is formed by the female die left part, the female die right part and the female die ejector block; in the forming process, a workpiece is clamped; the workpiece is prevented from running in the pressure forming process; and a correcting force generated by the die is acted on the turned position of the bent part, so that the effect of eliminating rebound is achieved.

Description

technical field [0001] The invention relates to a stamping die, in particular to a stamping die for bending a brake shoe wing plate of an automobile. Background technique [0002] Brake shoes are important security parts on automobile brakes, generally in the form of castings and welded parts. Because there are many defects in castings, such as air holes, sand inclusions, cold shuts, shrinkage cavities, cracks, etc., and the production cost is relatively high, the current brake shoes often adopt sheet metal stamping, bending, and then welding to form structures. It is composed of brake shoe wing plate, web plate, friction plate and other main parts. During the braking process of a car, a high-pressure liquid is established in the hydraulic system, and the high-pressure liquid pushes the two pistons in the brake wheel cylinder to expand outward, so that the brake shoe ends close to the brake wheel cylinder are separated to both sides, eliminating The reserved gap between th...
