不同压边工况下汽车用高强度钢板拉深性能研究
Deep Drawability of High Strength Steel Sheet under Different Blank Holder Force Conditions
摘要
Abstract
Based on benchmark cylindrical cup deep drawing scheme,a cylinder deep drawing scheme was designed to study deep drawability of the high strength steel ( HSS) sheet . HSS sheet SPCN440W - NS (1.2 mm) was drawn respectively under 70 kN and 10 kN blank holder force ( BHF) conditions,and drawing process was simulated by DYNAFORM software. The test and simulation results showed that HSS sheet SPCN440W - NS had better deep drawability. BHF had great influence on deep drawability of the HSS sheet. Workpiece had better surface quality under 70 kN BHF condition,and was easily wrinkled in its flange region under 10 kN BHF condition. The simulation accuracy of the DYNAFORM software under 70 kN BHF condition was higher than 10 kN BHF condition.关键词
