减小薄壁酚醛层压布管保持架加工变形的工艺改进

Improvement on Technology for Reducing Deformation of Cages Made of Thin-Walled Phenolic Cloth Laminated Tubes

针对薄壁酚醛层压布管保持架在加工过程中易产生变形的问题,提出多项改进措施:改进装夹方式;减少保持架装夹次数;增加保持架坯料长度;利用制作的拆取垫片附件代替手工拆取保持架;减少浸油次数并延长浸油时间。最终确定了保持架加工工艺的改进方案,实际加工表明,改进后工艺可显著减小薄壁酚醛层压布管保持架的加工变形,满足了设计使用要求。

In response to the problem of deformation during processing of cages made of thin-walled phenolic cloth laminated tubes,the various improvement measures are proposed:improving the clamping methods,reducing the clamping times of cages,increasing the length of cage blanks,replacing the manual labor with made disassembly gasket attachment for disassembly of cages,reducing the number and extending the time of immersion oil.An improvement scheme for processing of cages is finally determined,and the actual processing shows that the improved process can significantly reduce the processing deformation of cages made of thin-walled phenolic cloth laminated tubes,meeting the design and usage requirements.
