基于Archard理论的挤压次数对模具磨损量的影响分析
Analysis of influence of extrusion times on total die wear based on Archard theory
摘要
Abstract
Based on the fact that under discontinuous extrusion condition, former passes often have great effect on the next ones, so that the relationship between die wear of single process and total wear is not linear, the position with the largest amount of wear on the die surface was predicted, and the relationship between the extrusion times and the total die wear was estimated by combining modified Archard model which considered the influence of temperature on the die wear behaviors and finite element method (FEM) technology. As a result, an equation for evaluating the total die wear which considers the effects of extrusion times was established.关键词
