Abstract

The paper analyzes the drawing process in the context of the manufacture of large-sized spherical bottoms in production. The stages of computer modeling in the QForm software product for the initial workpiece made of aluminum alloy 1580 with a thickness of 1.5mm and a diameter of 426.9 mm are given, indicating the main process parameters, such as the material model, mechanical characteristics of the workpiece material, type of elements, kinematic loads, conditions of contact interaction of elements among themselves, etc. The thickness distribution on the spherical part of the bottom surface has been established. A complex method is used in the work including a comparison of the results obtained in an experimental press tool and in modeling.
