2.斜辊式转毂矫直原理与参数计算孔模式转毂矫直有许多缺点:(1)摩擦消耗的功大;(2)孔模消耗量大;(3)圆材表面易损伤;(4)圆材头部送入困难;(5)盘条尾部常随转毂转动而不能矫直;(6)送料受阻时,孔模或圓材磨损严重。用斜辊代替孔模,明显地克服了上述缺点。另外,斜辊还能产生送料 2. Skewed roller hub straightening principle and parameter calculation Hole mode hub turning has many disadvantages: (1) the friction power consumption of large; (2) hole mode consumption; (3) the surface of the round wood is easy to damage; (4) round head difficult to enter the head; (5) the tail of the wire rod often with the rotation of the hub can not be straightened; (6) feed blocked, the hole die or round of serious wear and tear. The use of diagonal roller instead of hole mode, obviously overcome the above shortcomings. In addition, skew rolls can also produce feed
