摘要
为优化冲压拉延中拉延筋参数,基于Autoform建立仿真模型,以阻力系数为评价指标,采用正交试验与方差分析,探究9项参数对拉延阻力的影响规律。结果表明:凹筋流入侧顶端圆角半径、凸筋高度等参数对拉延阻力的影响显著,而立壁角度、底端圆角半径的影响微弱。工程中调控关键参数可抑制起皱、破裂缺陷,提升模具调试效率,降低生产成本。
To optimize drawbead parameters in stamping processes,a simulation model is established by using Autoform,with the resistance coefficient as the evaluation criterion.Orthogonal testing and variance analysis are employed to investigate the influence laws of 9 parameters on drawbead resistance.The results reveal that parameters such as the top fillet radius on the inflow side of the concave drawbead and the height of the convex drawbead significantly influence drawbead resistance,while the wall angle and bottom corner radius have minimal impact.In engireering,regulating the key parameters can reduce defects such as wrinkling and cracking,thereby improving mold debugging efficiency and lowering production costs.
