本文应用上限法原理,建立了热态反挤压压力的计算公式,确定了热态反挤压凸模工作部分的合理形状,并将实测的热态反挤压压力与理论计算值进行了比较。
In this paper, the upper limit method principle is used to establish the calculation formula of reverse extrusion pressure in hot state. The reasonable shape of working part of hot reverse extrusion punch is determined, and the measured hot reverse extrusion pressure is compared with the theoretical calculation value .
