我厂套筒类零件的生产一直以来都是采用热时效的方式去应力,近期试验采用振动时效技术,取得成功。该批产品属于易变形的薄壁套筒类零件,但毛坯和半成品结构刚性大。产品精度和强度及耐磨性均要求较高,内孔尺寸精度最高为IT 6~7级,尤其是精度稳定性要求高。此产品批量大、规格多
The production of sleeve parts in our factory has always been to use thermal aging method to stress, the recent test using vibration aging technology, to achieve success. The products belong to the deformation of thin-walled sleeve parts, but rough and semi-finished structure rigid. Product accuracy and strength and wear resistance are demanding, the highest hole size accuracy of IT 6 to 7, in particular, high precision stability requirements. This product is large quantities, specifications and more
