制冷压缩机的主要零件之一——伐片的加工属于典型的薄板零件加工。过去加工合格率仅为20%左右,后来由于改革了磨削和热处理工艺,提高了精度,合格率提高到80%以上。本文介绍了伐片等薄板零件在加工中变形的原因和消除变形的办法。 One of the main components of refrigeration compressors - the cutting process is a typical sheet metal parts processing. In the past processing pass rate of only about 20%, and later due to the reform of the grinding and heat treatment process to improve the accuracy, pass rate increased to 80%. This article describes the reasons for the deformation of thin-plate parts such as cutting and processing in the processing and ways to eliminate the deformation.
