介绍某柴油机排气过渡管的加工工艺,分析空间尺寸较多的复杂管类零件的加工工艺及角度误差对空间尺寸的影响。通过角度在公差范围内的微量调整,解决了排气过渡管由于毛坯铸造及加工时找正存在的误差而造成气口处壁厚不均的问题。
The processing technology of a diesel engine exhaust transition pipe is introduced. The processing technology and the influence of the angle error on the space dimension are analyzed. By adjusting the angle within the tolerance range, the problem of uneven wall thickness at the gas outlet caused by the error existing in the casting and processing of the exhaust transition pipe is solved.
