Design of Rolling Strengthening Device for Bolt Transition Fillet Based on Ordinary Lathe
Transition fillet rolling strengthening is a technological method to improve the fatigue performance of ultra-high strength steel bolts.This paper introduces the structure composition and the detailed structural features of the important parts of the rolling strengthening bolt transition fillet device applied on the ordinary lathe,and gives the installation and application method of the rolling strengthening device.The device uses a single roller for rolling strengthening processing,which can not only meet the requirements of bolt fatigue strengthening,but also the operation is simple and fast,suitable for small batch bolt transition fillet strengthening processing,and has good practicability and economy in production.
