分析了影响纬纱板成形性能的主要因素:压边力、冲压速度以及摩擦系数。借助Dynaform软件对纬纱板拉深成形进行了单因素分析,得到了合理的压边力、冲压速度和摩擦系数取值范围。依据试验结果,用正交试验法对冲压参数压边力、冲压速度和摩擦系数之间的关系进行了分析,确定了最佳成形工艺参数。结果能为实际加工提供帮助。
The main factors influencing the formability of the weft yarn board are analyzed: blank holder force, pressing speed and friction coefficient. The uniaxial analysis of the deep drawing process of the weft yarn board was carried out by means of Dynaform software. The reasonable blank holder force, pressing speed and friction coefficient range were obtained. Based on the test results, the relationship between the blank holder force, the pressing speed and the friction coefficient of the stamping parameters was analyzed by orthogonal test to determine the optimum forming process parameters. The result can be helpful for the actual machining.
