摘要
通过对长度较大的小直径管形零件的工艺分析 ,介绍了一种利用直杆在一定压力下失稳的特性来成形的新方法 ,并对其工艺流程、模具原理、成形力计算和模具结构进行了详细分析。采用扩口压环模进行生产后 ,劳动强度大大降低 ,提高了生产效率。
The new method of shaping,which adopts the characteristic of straight rod's instability under certain pressure is introduced by process analysis of long and small diameter tube parts. The technological process,mold principle,forming force and mold structure is discussed in detail.Production efficiency and labor strength is improved by this process.
