锟锻法生产变截面汽车钢板弹簧,是通过一对反向旋转的模具,使钢板弹簧毛坯连续产生局部变形来实现的。因此,模具曲线展开后应与锻件形状相同,即锻件的形状决定了模具的形状。目前应用的梯形变截面弹簧,随着长度的增加,断面的高度尺寸也成比例的增加,反映在模具上,就是随着转角的增加,模具的向量半径也成比例的发生相 Kun forging production of variable cross-section car leaf spring, is through a pair of reverse rotation of the mold, so that the continuous production of leaf spring blank locally deformed to achieve. Therefore, the mold curve should be the same shape as the forging, that the shape of the forging determines the shape of the mold. The current application of trapezoidal cross-section of the spring, with the increase of length, the height of the section also increases proportionally, reflected in the mold, that is, as the angle increases, the mold radius of the vector is also proportional to the phase
