Car body front panel forming die with split type male die

Abstract

The invention discloses a car body front panel forming die with a split type male die. The car body front panel forming die comprises an upper die mechanism and a lower die mechanism, wherein the upper die mechanism comprises an upper die base and an upper forming female die, the upper forming female die is fixedly mounted on the upper die base, and an upper forming face is arranged at the bottom of the upper forming female die; and the lower die mechanism comprises a lower die base, a lower forming male die and a floating base, the lower forming male die is fixedly mounted on the lower die base, a lower forming face matched with the upper forming face is arranged on the lower forming male die, supporting columns are arranged at the four inner corners of the lower die base, the floating base is elastically connected to the lower die base, the lower forming male die penetrates through the floating base, a plurality of first guide columns are arranged at the bottom of the floating base, and avoiding grooves corresponding to the supporting columns are formed in the four corners of the floating base. According to the car body front panel forming die with the split type male die, the die assembly precision of an upper die and a lower die is guaranteed while parts are conveniently stripped, and the forming effect of the parts is guaranteed.

Description

technical field [0001] The invention belongs to the field of parts punching and forming, and in particular relates to a vehicle body front wall plate forming die with a split punch. Background technique [0002] The stamping process is a metal processing method, which is based on the plastic deformation of the metal, using the mold and stamping equipment to exert pressure on the sheet, so that the sheet is plastically deformed or separated, so as to obtain a product with a certain shape, size and performance. Component. [0003] The existing stamping die usually fixes the lower forming male on the floating plate to facilitate the stripping. The floating plate is easily affected by the lateral force when the mold is clamped, which leads to the insufficient precision of the mold clamping of the upper and lower molds, which affects the forming effect of the parts. Contents of the invention [0004] The purpose of the present invention is to provide a body front panel formin...
