Abstract：

Aiming at problems of life expectancy and failure testing of thermal die, the current research status of service environment simulation of plastic forming die at home and abroad was analyzed, and the simulation test method and device of service environment for thermal die under the condition of thermoplastic deformation were emphatically discussed. Then, the service environment of thermal forming die was obtained by simulating the change of stress amplitude and ambient temperature of blank in the process of thermal plastic forming, and the simulation test method and device for thermal plastic forming based on the service conditions of environment were proposed. The test device is mainly composed of PLC total control system, hydraulic pressure system, sound control prediction system, cooling system, heating system and torsion system, which can realizes three test modes including thermal fatigue, thermal friction wear and thermal fatigue friction wear. The research provides experimental support for the study of failure in the plastic forming process of thermal die.
