Analysis of formation and deformed state of thin-wall tube workpiece obtained by a new method of deformation

摘要

Increasing the capacity of power plants requires the production of high quality products. It is most expedient to obtain such products by forging methods, since these methods make it possible to obtain forgings with a high study of the metal structure. The aim of the paper is to analyze the deformation and deformed state of the forging obtained by forging methods on a cylindrical mandrel with notched radius dies with bevels. In the work, a finite-element model of the cogging tube workpiece has been developed. Recommendations for the selection of the workpiece optimal shape, tool and deformation mode have been developed. The results of the work allowed recommending for the production of unique high quality products with minimal allowances and expenses for a special tool.
