摘      要：In order to solve the problems of excess ovality and cross-section distortion of longitudinally submerged arc welding pipes after forming,a new three-roller continuous setting round process was *** process can be divided into three stages:loading stage,roll bending stage and unloading *** on the discretization idea,the mechanical model of the primary statically indeterminate problem of the longitudinally submerged arc welding pipes at the roll bending stage was established,and the deformation response was *** simulation and theoretical results show that there are three positive bending regions and three reverse bending regions along the circumference of the *** loading force of each roller shows growth,stability and downward trend with *** error between the theoretical fitting curve and the simulated data point is very small,and the simulation results verify the reliability of the theoretical *** experimental results show that the residual ovality decreases with the increase of the reduction,and the reduction of the turning point is the optimum *** addition,the residual ovality of the pipe is less than 0.7%without cross-section distortion,which verifies the feasibility of this process.
