采用冲压模具实现了管材螺旋槽成形。根据曲轴毛坯的特殊形状和成形工艺,在其螺旋槽成形模具设计中,使用浮动定位机构实现了曲轴毛坯在模具中的定位,依靠斜楔斜滑块机构完成螺旋槽成形,采用汽缸辅助斜楔斜滑块机构实现了成形凹模在模具中的定位与复位,并给出了螺旋槽工作尺寸的计算。该模具在生产中取得了良好的效果。

The spiral groove of pipe is formed by press die.For the special shape and production process of the crankshaft shell,it is difficult to design the die.Using the float positioning mechanism,the crankshaft shell can be fixed well in the die.Using inclined wedge and inclined slide block mechanism,the spiral groove of pipe is formed.(Using) cylinder aided inclined wedge and inclined slide block mechanism,the forming female die can be fixed and repositioned well in the die.The forming dimensions are given.
