Abstract: In order to reduce labor costs, while improving production efficiency and increasing output, in the refrigerator compressor industry, the requirements for intelligent manufacturing are getting higher and higher. Takes a certain type of compressor as an object, analyzes its bracket deformation during the bending and calibrating process in intelligent manufacturing, and considers the whole process as a quasi-static system according to the actual load. According to the actual loading of the bracket, the whole process is regarded as a quasi-static system. Based on ANSYS Workbench software to establish the finite element model of each process, calculate the stress and deformation results of the bracket. Then targeted improvement programs are proposed. In addition, the evaluation criterion of the stress result of the bracket is also established, and the concepts of stress coefficient S and maximum stress σ_MAX are introduced, so as to evaluate the risk of load and deformation of the optimization scheme in various different processes and give a definite conclusion. At the same time, mold processing was carried out for the improvement plan, and online verification was carried out, effectively improving the deformation problem of the base.
