Embodiment 1

[0026] like figure 1 The shown extrusion process of a high-strength aluminum alloy bending profile for a vehicle includes the following steps:

[0027] A. Prepare aluminum alloy raw materials according to the following parts by weight: Si: 1.0%, Fe: 0.25%, Cu: 0.045%, Mn: 0.50%, Mg: 0.75%, Cr: 0.12%, Zn: 0.10%, Ti: 0.03 %, single impurity ≤ 0.05%, total impurities ≤ 0.15%, the balance is Al, the prepared aluminum alloy raw material is added to the melting furnace and evenly mixed and then smelted into liquid aluminum alloy, and the liquid aluminum alloy is smelted into an aluminum alloy ingot;

[0028] B. Homogenize the molten aluminum alloy ingot at a temperature of 550-580°C, and the homogenization treatment time is 4-6h;

[0029] C, the aluminum alloy ingot of homogenization treatment is placed in the extrusion die of the extruder and extruded to obtain the required aluminum alloy profile, wherein the extruder is a 1250T extruder, and the heating temperature of the extrusi...

Embodiment 2

[0035] The difference between Example 2 and Example 1 is that the aluminum alloy raw material composition in Step A is: Si: 1.1%, Fe: 0.25%, Cu: 0.045%, Mn: 0.55%, Mg: 0.85%, Cr: 0.20%, Zn: 0.10%, Ti: 0.03%, single impurity ≤ 0.05%, total impurities ≤ 0.15%, and the balance is Al.

Abstract

The invention belongs to the field of aluminum alloy forming and relates to an extrusion process of a high strength aluminum alloy bending section bar for a vehicle. An aluminum alloy ingot adopts a ladder heating mode, the heating temperatures of the head, the middle and the tail of the aluminum alloy ingot are 480-510 DEG C, 470-500 DEG C and 460-490 DEG C in sequence, the extrusion speed is 4.5-5.5 m / min, and after the aluminum alloy section bar subjected to stretching and straightening is subjected to standing for 6-8 hours, bending is carried out and the bending angle is 100-120 degrees;and the bent aluminum alloy section bar is subjected to artificial aging heat treatment, the aging temperature is 175+ / -5 DEG C, and the heat preservation time is 8 h. The extrusion process is carriedout by adjusting the alloy component content and matching with a low-temperature high-speed process system, and by means of the processing and strengthening mode that bending is carried out before aging, the surface quality and mechanical properties of the finally prepared high strength 6082 aluminum alloy section bar meet the standard requirements.

Description

technical field [0001] The invention belongs to the field of aluminum alloy forming, and relates to an extrusion process of a high-strength aluminum alloy bending profile for vehicles. Background technique [0002] As modern industry gradually moves closer to light industry, new energy vehicles are developing rapidly. New energy vehicles are based on lightweight, energy saving and safety considerations. The spatial organization framework mainly composed of aluminum extrusion profiles will extrude After forming, the aluminum alloy profile products are processed by welding, bending and other processing methods to maximize the realization of automotive products with high strength and safety. [0003] Traditional automotive bending parts are built on 6-series medium-strength 6005A, 6061 and other aluminum alloys, but with the development of science and technology and the advancement of industrial modernization, there will be a large market demand for higher-strength aluminum all...
