Manufacturing process of aluminum differential case shell

Abstract

The invention relates to the related technical field of electric vehicle differential case casting, and discloses a manufacturing process of an aluminum differential case shell. The manufacturing process comprises the following raw materials including, by weight, 2.0%-3.0% of Si, 1.2%-2% of Ti, 0.1%-0.25% of Cu, 0.2%-1.2% of Zn, 1.2%-1.3% of Mg, 0.1%-0.3% of Fe, 0.5%-0.6% of Ni and the balance A1 and inevitable impurities. The manufacturing process comprises the following steps that S1, primary burdening is conducted, specifically, the raw materials are prepared according to the required burdening, and elementary substance raw materials or alloy raw materials with ingredient components are adopted; and S2, smelting is conducted, specifically, the raw materials prepared in the S1 are dried and guided into a smelting furnace for high-temperature smelting. According to the manufacturing process of the aluminum differential case shell, the components of an aluminum differential case are subjected to primary burdening and then are smelted to be in a molten state, after impurities in molten metal are removed, the aluminum molten metal in the molten state is subjected to precise secondary component analysis, the machining quality of subsequent heat treatment of the differential case shell is improved, and the manufacturing process of the aluminum differential case shell of an electric vehicle is effectively optimized.

Description

technical field [0001] The invention relates to the technical field of electric vehicle differential case casting, in particular to an aluminum differential case shell manufacturing process. Background technique [0002] Electric vehicles, that is, electric drive vehicles, have another name called electric drive vehicles. Electric vehicles are divided into AC electric vehicles and DC electric vehicles. Generally speaking, the electric vehicle uses the battery as the energy source. Through the controller, the motor and other components, the electric energy is converted into mechanical energy movement to control the current and change the speed of the vehicle. The differential is an important component of the electric vehicle components. play an important role in the driving of the car. [0003] The differential is composed of planetary gears, planetary gear carriers (differential case), half shaft gears and other parts. The power of the motor enters the differential through...
