Abstract

The invention relates to the technical field of automotive part manufacturing and discloses a fracture-preventing automotive sheet metal part stamping device. The device comprises a base. Stand columns are fixedly mounted at the two ends of the upper surface of the base. A hydraulic pump is fixedly mounted between the two stand columns through a fixing rod. The bottom of the hydraulic pump communicates with an oil outlet pipe and an oil inlet pipe. A hydraulic cylinder is fixedly connected between the two stand columns. The top of the hydraulic cylinder communicates with the oil inlet pipe and the oil outlet pipe. A hydraulic telescopic rod is movably connected with the bottom of the hydraulic cylinder. According to the fracture-preventing automotive sheet metal part stamping device, by arranging a male die and a female die, the hydraulic telescopic rod drives the male die to stamp downwards so that a sheet metal part can be in a U shape, the corners, connected with the two side faces, of the lower surface of the male die are circular beads, and the corners where the upper surface of the upper surface is connected with the inner side are circular beads, so that stamping force to the sheet metal part is buffered during stamping, the sheet metal part is protected, fraction of the sheet metal part in the stamping process is avoided, the stamping effect is good, and the stamping quality is improved.

Description

technical field [0001] The invention relates to the technical field of automobile parts manufacturing, in particular to an anti-fracture stamping device for automobile sheet metal parts. Background technique [0002] Sheet metal parts are products processed by sheet metal technology. Everyday life is inseparable from sheet metal parts. Sheet metal parts are produced through filament power winding, laser cutting, heavy processing, metal bonding, metal drawing, plasma cutting, precision Welding, roll forming and sheet metal bending forming, die forging, water jet cutting and precision welding, sheet metal is a comprehensive cold processing process for sheet metal, including shearing, punching, cutting, folding, welding, riveting, Splicing and forming, etc., its remarkable feature is that the thickness of the same part is consistent, sheet metal parts have the characteristics of light weight, high strength, electrical conductivity and low cost, and have been widely used in the ...
