摘要
给出了曲面零件带槛拉深时的阻力计算方法,并以此为基础,推导了槛的成形力、最小压边力公式。为了保证压槛时不起外皱并使毛坯完全包槛,初始毛坯的几何参数还应满足一定的限制条件。
The formula of resistance of curve part with edge-bead in drawing has been given,upon which forming force and minimal blankholding force have been deduced.For purpose of no wrinkle while edge-bead being held by blank completely,the geometrical parameters of the primary blank have to meet some limits.
