Abstract

According to the requirement of electric upsetting process design for 30MnSi prestressed concrete steel rod (PC steel rod), a set of electric field-temperature field-structure field simulation system was established on deform platform combined with practical production experience. Using this system, the upsetting process of PC steel rod under different technological parameters was simulated, and the forming rule and surface shape of the upsetting head under different technological schemes were analyzed. The forming shape of the upsetting head was taken as the response parameter. Box-Behnken design-response surface method was used to optimize and verify the three main parameters of upsetting temperature, upsetting speed and clamping distance, which can affect the forming quality of the header. The simulation results met the requirements of enterprises on the performance of the prefabricated parts.
