Design of Installation for Electric Resistance Heating of Workpieces for Stamping Complex-Profile Parts on an Automatic Cold Upsetter

Abstract—An installation is designed for preliminary electric resistance low-temperature heating of workpieces for stamping complex-profile parts made of carbon and alloy steels on automatic cold upsetters. A schematic diagram of the installation has been developed, and the main technical characteristics of the preliminary electric resistance low-temperature heating installation have been determined. The use of this installation will reduce the deformation forces during stamping by 1.5 times and the loads and will increase the life of the working tool by 1.5–2.5 times.
