Problems solved by technology

[0004] However, in the specific operation process, firstly, it will face the problem of long time consumption, and secondly, in the process of processing, especially for temperature control, the processing effect of aluminum alloy sheet is mainly determined by temperature. The properties of plasticity, toughness, internal stress, strength or hardness will fluctuate irregularly with the processing conditions (temperature), and it is impossible to grasp the properties in real time, so the processed materials still cannot meet the process requirements, and it is difficult to make Therefore, in order to solve such problems, we propose a rapid aging process method for aluminum alloy plates and its intelligent control system

Description

technical field [0001] The invention relates to the technical field of aluminum alloy plate processing, in particular to a rapid aging process method for aluminum alloy plates and an intelligent control system thereof. Background technique [0002] In order to improve the relevant characteristics of aluminum alloy sheets, it is necessary to carry out aging treatment on aluminum alloy sheets. Aging treatment refers to the solution treatment of metal or alloy workpieces (such as low carbon steel, etc.), after high temperature quenching or a certain degree of cold working deformation. , a heat treatment process that maintains its shape, size, and performance over time at a higher temperature or at room temperature. [0003] Generally speaking, after aging, the hardness and strength increase, and the plastic toughness and internal stress decrease. Steel with high carbon content immediately obtains high hardness after quenching, but its plasticity becomes very low, while aluminum...
