摩擦状况是评定拉深成形难易甚至成功与否的重要指标之一 ,而法兰部分又是拉深时的主要变形区域。通过探针法来获取各种情况下不同部位的摩擦系数 ,进而分析出方盒件的成形特点 ,并分析出各种工艺参数与材料参数对成形时摩擦的影响规律 ,以便在实际生产中能对摩擦状况进行控制。
Friction status is one of the most important indexes to evaluate the difficulty or even the success of drawing, while the flange part is the main deformation area when drawing. Through the probe method to obtain the friction coefficient of different parts under various conditions, and then analyze the forming characteristics of square box, and analyze the influence of various process parameters and material parameters on the friction during forming, so that in actual production Control of friction conditions.
