Title Surface of the metal pipe rolling test device
designed to strengthen
Abstract
This paper studies the rolling test equipment to strengthen a metal pipe surface material.Design of a main structure of the rotary drive mechanism through the large surface of the metal pipe to the torque generated enormous torque. So that the surface of the metal coffin superplastic deformation, So that the surface layer of nanocrystalline grain fine. Pressurizing means of the apparatus from the surface, the polishing surface of the rotary drive means, the data acquisition and data processing system, a hydraulic control system. In this body, we need to be able to select a big pressure on the pipe surface equipment. Rotary drive means for selecting the drive worm, because the worm drive with a larger transmission ratio, it is able to produce relatively large torque, noise it produces relatively small,iItself also has a self-locking performance, relatively safe.
