Abstract

The invention belongs to the technical field of battery tray processing, and particularly relates to a processing technology for an aluminum alloy battery tray of a passenger car. The processing technology comprises the following steps of casting, namely adding the prepared raw materials into a smelting furnace for melting according to technological requirements, and effectively removing miscellaneous slag and gas in a melt by degassing and deslagging refining means; combining an extrusion process for realizing isothermal extrusion by adopting variable-speed regulation and control with a gradient heating process, reducing the temperature of an aluminum bar which is heated before extrusion gradually from front to back along the axis direction of the aluminum bar to form a temperature gradient and realizing isothermal extrusion, so that aheated and processed product is uniform in core surface temperature, bright in surface color and small in mechanical property deviation; and metal elastic deformation generated when a die bears high-temperature and high-pressure heat friction is reduced and avoided, the current situation that the size deviation of the head and the tail of an extruded long material product is larger is effectively improved, and meanwhile, it can be guaranteed that the surface temperature is basically consistent when a profile is discharged, and the product quality is greatly improved.

Description

Technical field [0001] The present invention belongs to the technical field of battery tray processing, and is specifically involved in a passenger car aluminum alloy battery tray processing process. Background technique [0002] The application of aluminum in new energy auto parts mainly has a body, hub, chassis, anti-collision beam, floor, power battery, and seat. At present, new energy vehicles have used aluminum alloy profiles to make electric vehicle power battery trays, and further improve the degree of lightweight of new energy vehicles. The application advantage of aluminum alloy in the light weight of automobiles is that the density is small (2.73 g / cm3), the corrosion resistance is good, the plasticity is excellent, from production costs, parts quality, material utilization, manufacturing technology, mechanical properties, sustainable development. Havilled the unparalleled superiority of other lightweight materials, the aluminum alloy will become the preferred lightwe...
