弹塑性拉弯原理不仅在连续拉弯矫正机中应用,而且是辊式板材矫正机辊形调整的理论依椐。近年来我们应用这一原理设计热轧铝卷材的卷取设备和冷轧机的展平辊,结果十分满意。下面将分别介绍弹塑性拉弯原理和几个设计应用。一、弹塑性拉湾原理板带材在弹性拉弯变形下,不同于纯弯曲,它的弯曲中塑性层不是板带材的几何中心层,而是移向弯曲内侧。但弹复时,拉力仍 The principle of elastic-plastic bending is not only applied in the continuous bending-bending machine, but also the theoretical adjustment of the roll-shaped adjustment machine. In recent years, we apply this principle to design hot rolled aluminum coil winding equipment and cold rolling mill flattening roller, the result is very satisfactory. The following will be introduced elastoplastic bending principle and several design applications. First, the elastic and plastic pull Bay Principle Plate bending elastic deformation, different from the pure bending, bending the plastic layer is not the geometric center layer of the strip, but to the inside of the bend. But when the bombs, pull still
