Abstract

An advantage of TUBE SPINNING process is high accuracy of products. Balancing forces among rollers is one of the most effective parameters on product accuracy in this process. UNBALANCE FORCEs cause mandrel deflection that directly reduces product thickness accuracy. UNBALANCE FORCEs also reduce surface quality of the product. In this paper, a procedure is proposed to omit UNBALANCE FORCEs between rollers and improve product accuracy. For this purpose, rollers forces are calculated as functions of ROLLERS RADIAL POSITIONs. Then coefficients of these functions are calculated from FEM simulations by ABAQUS software. Using these functions the radial positions of rollers are obtained such that the UNBALANCE FORCE among rollers is omitted. As a result, the mandrel deflection due to rollers UNBALANCE FORCE is reduced and the accuracy of product is increased. In verifying the method, mandrel force before and after applying the method has been compared and it is observed that this force is reduced by 97 percent.
