THE CALCULATION OF THE PREFORMATION PARAMETERS ON THE BASIS OF MODELING IN THE SOFTWARE COMPLEX DEFORM 3D

Torgonin K., Shirokov V.V.

In recent years, the oil and gas industries have been developing significantly. In this regard, there was a great need for the construction of main pipelines, which consist of pipes and connecting parts. The production of connecting parts of pipeline has not been studied enough to date. This article describes the process of stamping halves of stamped-welded elbows. During the stamping operation, the workpiece wall is thinned. The process of modeling this operation in a software of modeling by finite element method Deform-3D is described. The place of the greatest thinning of the wall was determined with the help of Deform-3D. The results of modeling and experimental production coincided. The main factors that may influence the degree of thinning were identified. Experimental calculations were performed in Deform-3D with a variation of these factors. As a result of the experiments carried out, the most significant factor was determined and an option was proposed to solve the problem of wall thinning. Solving this problem will help reduce the cost of production by 1.5 times.
