Finite Element Analysis of the Frame of Straightening Machine with Twelve Rolls for Tubes

Abstract:

The frame of a straightening machine is a body of the equipment, and bears all loads exerting on the machine. It is necessary for the frame to have strong strength and stiffness so that the machine can work under normal condition. What is more, because control technology for a hydraulic or servo system is applied to this equipment, it is also necessary to understand the variation laws of frame under loads, so that the effects of pressure protection and position control of rollers could be better and the laws could be provided for designing control system. In this paper, the deformation maps of the frame under loads are got by finite element analysis, distribution laws on stress and displacement of the frame are obtained when it is working, and suggestions are proposed for improving the functions of frame and quality of tubes.
