| 摘 要： | 聚四氟乙烯波纹管的材质有弹性、结构可伸缩，车削加工时装夹困难，不易保证波纹尺寸精度。为此确定了特定
的波纹管车削工艺流程，对弹性毛坯设计了弹性夹头及通孔套夹具，使用定尺寸刀具保证波纹尺寸，使波纹管加工精度
满足设计要求，密封性能稳定可靠，使用寿命长，已广泛使用在化工泵机械密封上。该工艺方法简便高效、实用可靠，对
其他塑料弹性薄壁零件的加工有很好的借鉴作用。

| Abstract: | PTFE bellows have elastic material and structure of expanded and contracted. it is hard to clamp in turning
and assure dimension accuracy of bellows. Turning process of bellows was proposed, elastic clamp and hole sets fixture
were designed for the blank, special tool was applied for dimension of bellows, working precision of bellows could meet
design requirements, seal performance was stable and reliable.the life length was long, it has been widely used in
mechanical seals of chemical industry pump. The processing method was not only convenient and efficient but also
practical and reliable. it had commendable value for machining of other flexible plastic thin parts. |
