Abstract

The invention provides a method for preparing a 6-series aluminum alloy profile, which includes the steps of heat treatment, homogenization treatment and extrusion treatment. In the extrusion treatment, the extrusion is carried out by means of segmental speed extrusion, and the segmental speed extrusion The mold used in the pressing process includes an upper mold, a lower mold and an exhaust assembly. In the present invention, by optimizing the aluminum alloy extruded mold, an exhaust assembly is arranged on the contact surface of the upper mold and the lower mold of the mold, so that the contact surface is connected with the outside world, and the suction phenomenon and disengagement action can be fundamentally eliminated, and in this Under the extrusion conditions limited by the invention, the stability of extrusion and the quality of extrusion can be guaranteed; the invention can effectively solve the problem of false joints in the extrusion process of 6 series aluminum alloys, and obtain smaller precipitated phases and more uniform The advanced 6-series aluminum alloy profiles help to reduce production costs.

Description

technical field [0001] The invention relates to the field of preparation of aluminum alloy profiles, in particular to a method for preparing 6-series aluminum alloy profiles. Background technique [0002] Aluminum is considered to be the most economical and practical in many application fields. Adding alloy elements and using heat treatment to strengthen aluminum as a structural material results in the birth of aluminum alloys. Among them, 6-series aluminum alloys are also called "aluminum-magnesium-silicon alloys". It is a heat-treated corrosion-resistant aluminum alloy with high strength and corrosion resistance and good uniformity. It is a relatively popular product in the market at present. It is especially important in engineering applications and is mainly used for extrusion profiles. Due to the use of multi-piece combined molds in the conventional production of 6-series aluminum alloys, false joints are prone to occur during the extrusion process of 6-series aluminum ...
