One of the urgent tasks in the manufacture of cylindrical shells is to improve their performance and quality by developing technological processes based on new methods of metal treatment by pressure, for example, on drawing. A distinctive feature of drawing with thinning was the use of dies with a periodically changing profile of the bearing. The use of such dies creates additional shear strain during the forming, which affects the structure of the material and the performance of the product. This article presents the results of simulating the drawing with wall thickness reduction in QForm 7 and analyzes the effect of die geometry on technological force and stress-strain state.
