This paper presents a simulation of square bar extrusion using the finite element method in QForm software. The sequence of simulation stages is described and verified using an example of extruding AD31 alloy. The geometry of the extrusion tool (die) was improved to reduce material damage and eliminate profile distortion. It was found that rounding the corners and adding a calibrating section to the die provides improved performance. The analysis of metal heating from plastic deformation is also provided. The study highlights the importance of computer modeling for optimizing tools and increasing the efficiency of the metal forming process. Specifically, the initial and final die geometries were compared to assess the impact on product properties. Recommendations are provided for using simulation in the practice of developing metal forming process technologies. The benefits of using QForm software over alternative solutions are highlighted, including access to a comprehensive material database and robust technical support. The improved die design resulted in reduced plastic deformation and improved product quality. Finite element analysis significantly accelerates the development and testing of tools, providing the ability to develop optimal designs that account for various factors.

A finite element model of the deformation zone during cold drawing on a movable mandrel has been developed and justified. This makes it possible to determine the state of the metal, calculate its damage and the shape of the die channel, while the configuration of the first transition is taken as the initial one to obtain the second transition.

The step-by-step construction of a computer model of the process of long-angle drawing of profile pipes is considered. The minimum dimensions of the blanks have been determined, the use of which ensures the necessary dimensions of the finished product. The scheme of applying a deforming force with size adjustment in the current state during step-by-step deformation is taken into account. Geometric and finite element models have been obtained that make it possible to find all the parameters of the deformation site during the drawing process.

The construction and substantiation of a finite element model of the capillary tube running-in process, which was obtained by drawing on a fixed mandrel, are considered. The rolling rolls are cylindrical and absolutely rigid. The condition for performing the work is a comparison of the resulting gap between the pipe and the mandrel and the facet formed during deformation. The solid-state model of the process is described by an adaptive grid. Under these conditions, an informative model was obtained, which was used in parametric analysis.
