Continuous mold for rear door sill reinforcement plate of automobile

Abstract

The invention discloses an automobile rear doorsill reinforcing plate progressive die. The automobile rear doorsill reinforcing plate progressive die comprises an upper die body and a lower die body corresponding the upper die body. The upper die body is sequentially provided with a first pressure plate, a second pressure plate and a third pressure plate. First trimming knife block assemblies, a second trimming knife block assembly, third trimming knife block assemblies and fourth trimming knife block assemblies are arranged on the upper die body and extend to the position above the first pressure plate. A first forming knife block and a first forming pressing block are arranged on the second pressure plate. A female die extending to the position above the second pressure plate is arranged on the upper die body. A male die corresponding to the female die is arranged on the lower die body. A second forming pressing block, a second forming knife block, a third forming knife block and a third forming pressing block are sequentially arranged on the third pressure plate. By means of the above manner, the automobile rear doorsill reinforcing plate progressive die is high in production efficiency and good in stability; operators do not need to feed materials repeatedly by hand; operation is quite safe; and locating errors caused by multiple times of locating are eliminated.

Description

technical field [0001] The invention relates to the field of stamping dies for auto parts, in particular to a continuous die for a rear door sill reinforcement plate of an automobile. Background technique [0002] The automotive industry is constantly developing, and stamping technology is also constantly improving and innovating. [0003] In the traditional stamping production, the automotive door sill reinforcement plate parts usually use engineering molds, and the process adopts the steps of stretching - trimming punching - flanging - flanging - shaping. [0004] Disadvantages of this engineering model: [0005] 1: The content of the process is relatively large, requiring more manpower, and the production efficiency is low; [0006] 2: Each mold needs to use the same positioning repeatedly, and the positioning is prone to errors in all aspects of processing and production, which affects the accuracy of parts; [0007] 3: The weight of the part itself is heavy, and the ...
