Abstract

Cold forging is an ecological production technology for high-strength metal parts. Tool fatigue is the most significant constraint preventing the enhancement of process limits towards complex part geometries. To better analyse tool fatigue, a test method for dies under high inner pressure is researched. The load usually transmitted by the workpiece is applied by compression of elastomers. Results show that the test is able to accurately model the fatigue behaviour of forging tools including crack propagation and the influence of prestressing systems. Compared to conventional fatigue tests, the analysis of different reinforcements and tool geometries is enabled.
