利用斜冲模对12×4J轮辐进行翻边时,将变形区看做是平面应力状态,探讨了翻边高度、初始孔径及斜冲模角对翻边变形区径向应变和轴向应变的影响,对12×4J轮辐翻边不同斜冲模角下的冲压力变化规律进行了计算.结果表明,影响变薄的因素除斜冲角以外,还与其周向应变有关.厚向应变和径向应变随斜冲角增大而增大,但翻边力却正好相反,综合考虑,斜冲角取α=30°～35°比较理想. When the 12 × 4J spokes were beveled by using the oblique die, the deformation zone was regarded as the plane stress state. The influences of flange height, initial aperture and bevel angle on the radial strain and axial strain of the flange deformation zone were discussed. The results show that the factors influencing the thinning are related to the circumferential strain except the bevel angle, and the thick strain and radial strain Inclined angle increases and increases, but the turning force is exactly the opposite, considering, oblique angle α = 30 ° ~ 35 ° is ideal.
