Abstract

The invention discloses a production process for aluminum alloy battery boxes. The production process comprises the following steps: aluminum blocks are placed in a smelting furnace for smelting underthe condition of 650-690 DEG C to form molten aluminum; tungsten blocks, iron blocks, titanium blocks, zinc blocks, zirconium blocks, magnesium blocks, nickel blocks and manganese blocks are fed in the smelting furnace for smelting in sequence in proportion according to melting points from high to low in the environment of 1300-1500 DEG C; after smelting by 5-9 min, the molten aluminum is uniformly fed inside for smelting by 20-30 min; formed pouring liquid is poured in battery box molds for electric vehicles; the pouring speed is maintained within 30-50 ml / s; the molding is waited; after molding and recovery to the normal temperature, products are placed in a heating furnace for heating to 200-220 DEG C; and the temperature is maintained by 40-60 min under the conditions. Through the production process, the aluminum alloy battery boxes achieve high strength, and the service life of accumulators arranged therein can be effectively prolonged.

Description

technical field [0001] The invention relates to the technical field of battery box preparation, in particular to a production process of an aluminum alloy battery box. Background technique [0002] The composition of electric vehicles includes: electric drive and control systems, mechanical systems such as drive force transmission, and working devices to complete established tasks. The electric drive and control system is the core of electric vehicles, and it is also the biggest difference from internal combustion engine vehicles. The electric drive and control system consists of a drive motor, a power supply, and a speed control device for the motor. The rest of the equipment of electric vehicles is basically the same as that of internal combustion engine vehicles. The battery is the core mechanism of electric vehicles. In the traditional technology, when placing the battery, it is enough to use a simple box to wrap it, so that the stability and safety of the battery are ...
