Problems solved by technology

In summary, this method is only suitable for 7075 aluminum alloy, and the applicable surface is narrow; the process flow is complicated, and there are strict requirements on the cooling rate and cooling time in the forced cooling stage, and the operation is difficult. Forming temperature, to avoid excessive heat loss when the aluminum alloy base material is transferred, and the transfer time is required to be controlled within 3 seconds, which will also be difficult to operate, prone to errors, and increase the scrap rate; the aluminum alloy base material is solid solution treated , Forming first and then quenching, if not quenched in time, alloy atoms will precipitate rapidly, affecting the effect of subsequent aging treatment, thereby affecting product performance

Abstract

The invention discloses an aluminum alloy rapid forming controllability integration method, and relates to the technical field of aluminum alloy hot stamping forming and heat treatment processes. An aluminum alloy base material is firstly subjected to solution treatment after being prepared, and then is subjected to in-mold quenching treatment after the solution treatment, so that the purpose of rapid cooling is achieved, the plasticity and strength of the aluminum alloy base material are improved, then heat formation is performed, and finally, aging treatment is carried out to improve the strength. According to plasticity improvement of aluminum alloy base materials of different marks, a cooling circulating water channel is arranged in a rigid mold, the base materials subjected to solution treatment are rapidly cooled, the quenching purpose is achieved, then the plasticity of the base materials is improved, the plasticity of plates can be kept for a long time, and a good foundation is laid for subsequent hot forming single-pass even multi-pass forming. According to the aluminum alloy rapid forming controllability integration method, the aluminum alloy can keep excellent forming performance for a long time, and then the quality of aluminum alloy hot forming parts is improved.

Description

technical field [0001] The invention relates to the technical field of aluminum alloy hot stamping forming and heat treatment technology, in particular to a controllable integration method for rapid forming of aluminum alloy. Background technique [0002] The traditional aluminum alloy hot forming method is to hot form the aluminum alloy base material in a hot environment, and then perform solution treatment, quenching and aging treatment on the formed parts after stamping, so as to improve the strength of the parts, but after the above heat treatment After the process, the performance, shape, and size of the formed parts change greatly with time, especially in the forming of complex and thin-walled aluminum alloy parts, which seriously affects the final accuracy. [0003] After the aluminum alloy base material is prepared and stamped into a product, a natural aging phenomenon will occur. This phenomenon will increase the strength of the material, thereby reducing the stampi...
