Abstract

The invention discloses a bending and shaping stamping die, which comprises an upper die holder, a lower die holder, a backing plate, fixed plates, an upper bending pressure plate, bending punches, a lower ejector plate, a lower bending insert and lower bending baffles, wherein the backing plate is arranged below the upper die holder; the fixed plates are arranged on the two sides of the backing plate; the upper bending pressure plate is arranged at the middle part of the backing plate; the bending punches are arranged between the upper bending pressure plate and the two fixed plates in a way of swinging a certain angle; the lower ejector plate is arranged on the lower die holder; the lower bending insert is arranged on the lower ejector plate and in a position corresponding to the upper bending pressure plate; the lower bending baffles with a certain inclination angles are arranged on the two sides of the lower ejector plate on the lower die holder; the inclination angles of the lower bending baffles are matched with swinging angles of the bending punches. According to the bending and shaping stamping die, the aim of shaping can be fulfilled during bending, so that the reject ratio of a product is lowered, and the machining cost of the product is lowered.

Description

technical field [0001] The invention relates to a mold structure, in particular to a bending and shaping stamping mold. Background technique [0002] Stamping die is a special process equipment for processing materials (metal or non-metal) into parts (or semi-finished products) in cold stamping processing, called cold stamping die (commonly known as cold stamping die). Stamping is a pressure processing method that uses a mold installed on a press to apply pressure to the material at room temperature to cause separation or plastic deformation to obtain the required parts. [0003] At present, traditional bending and stamping dies process bending parts with relatively large resilience, often causing customer complaints due to poor rebound angle of the bending edge, and these defective products need to be reshaped by plastic molds, which has processing costs High disadvantage. Contents of the invention [0004] The purpose of the present invention is to provide a bending an...
