| 摘 要： | 根据被切分件及切分楔的受力模型,利用数学分析得出极值,求得切分楔角2θ=2arctg(-μ+(μ~2+1)~(1/2))时,切分力X(μ,θ)有极大值。在一定条件下,摩擦系数μ值确定后,可求得θ值,从而设计出最佳切分楔角:当μ值增大,最佳切分楔角相应减小。

| Abstract: | A mechanical model describing the relation between the slitting angle and rolled stock under slitting rolling is developed to analyze mathematically theslitting angle. It is found that if the slitting angle 20=2arctan (f2+1)~(1/2),the slitting force is up to its maximum value. By test and calculation, the friction coefficient f can be determined under certain conditions. Thus, the value of slitting angle can be found out optimally. When f increases, the optimal angle will be decreased. |
