Embodiment Construction

[0015] It should be understood that the preferred embodiments are only for illustrating the present invention, but not for limiting the protection scope of the present invention.

[0016] For convenience, this embodiment takes a certain type of automobile beam as an example for illustration. Its material is 6082 aluminum alloy, which is supplied in T4 state and accepted in T6 state. The mechanical properties of the existing technology after aging are lower than the technical agreement standard or unstable. Seriously affect the production cycle.

[0017] The present invention proposes a new production process, which can improve the mechanical properties of the above-mentioned 6082 aluminum alloy beam. The method includes the control of raw material preparation, beam production (this product is extrusion molding) and aging process, and the specific control is as follows:

[0018] 1) Mass percentage of ingot alloy composition: Si: 1.0%~1.1%, Fe: ≤0.21%, Cu: ≤0.05%, Mn: ≤0.44%~0.4...

Abstract

The invention discloses a production process of a high-performance 6082 aluminum alloy cross beam product, and belongs to the technical field of processing of aluminum alloys. The production process comprises respective control of such procedures as raw material preparation, product production and aging. As the production process controls all parameters in the production process, the product mechanical performances are satisfied; meanwhile, the parking effect phenomenon is weakened; and after the product is parked by 30 days, through aging of 145+-3 DEG C*10 h, the mechanical performances are still qualified, the production demands are satisfied, and the guarantee is provided for later use of customers.

Description

technical field [0001] The invention belongs to the technical field of aluminum alloy processing, and in particular relates to a production process of a high-performance 6082 aluminum alloy beam product. Background technique [0002] 6082 aluminum alloy materials are widely used, and most of its products are supplied in T4 state and accepted in T6 state. After aging in a fixed system at 145±3℃×10h, the mechanical properties of such products cannot meet the requirements of the technical agreement; if artificial aging is carried out within 6 hours after production, the mechanical properties can meet the requirements, but the value exceeding the standard requirements is not much, and the batch There are hidden dangers in production. When artificial aging is carried out after parking for more than 6 hours or longer, its mechanical properties will drop significantly. According to the length of parking, it can drop by 20-50MPa, which is far below the technical agreement standard,...
