Problems solved by technology

[0005] However, the ductility of magnesium-aluminum alloy is relatively poor, it is easy to wrinkle or crack during stamping, and the stamping force is difficult to control, the processing is difficult, and the yield is low
[0006] Moreover, the powder of magnesium-aluminum alloy often sticks to the stamping die during stamping, causing the surface of the product to be scratched, affecting product quality and die life.

Abstract

The invention discloses a machining method of a vacuum booster shell of a magnesium-aluminum alloy. Proper raw materials are selected; pressing force P in each drawing procedure of workpieces and pressing force P' in each shaping procedure of the workpieces are precisely calculated; then, analog models are built in analysis software for simulation analysis to determine precise deformation in eachpunching procedure; punching molds in each procedure are manufactured according to analysis results for trial production and adjustment according to punching conditions until qualified products are produced; and then, the large-batch punching production is performed. The machining method can guarantee machining of high-quality magnesium-aluminum alloy booster shells, and realizes lightness of thebooster shells; and the magnesium-aluminum alloy shells produced by the method are high in yield, so that the product production cost is greatly reduced. The invention further discloses a punching mold structure of the shells.

Description

technical field [0001] The invention relates to a stamping process and a stamping die for a magnesium-aluminum alloy plate, in particular to a processing method for a magnesium-aluminum alloy vacuum booster housing and a stamping die for drawing and forming. Background technique [0002] The lightweight of automobiles has also become the main trend and trend of current automobile development. On the premise of ensuring the strength and safety performance of the car, the weight of the car should be reduced as much as possible, so as to improve the power of the car, reduce energy consumption and reduce air pollution from exhaust emissions. According to data, for every 100kg reduction in the overall weight of the car, the fuel consumption per 100 kilometers can be reduced by about 0.5L, and the carbon dioxide emission can be reduced by about 5g / km. [0003] Automobile brake vacuum booster is a safety component in the vehicle braking system. By controlling the pressure differe...
