The article presents the process of reducing the pipe and the influence of the shape of the tool on the geometric parameters of the cylinder. Charge material tube is precision welded cold drawn with an outer diameter ø 57 mm, made of stainless E355. Reduced pipe is used for cylinder hydraulic shock absorber. Formed cylinder is part of the structure MacPherson strut front suspension vehicle. Tube reduction process is carried out with cold working by using a hydraulic press. Analysed the influence of the diameter of the tool ø and profile angle 􀄮 transition into basic the geometric parameters of the deformed cylinder: inner diameter, wall thickness, pipe cylindrical deviation effect. The result of numerical simulation is a map of HMH stress. As well as the effect of the transition profile, angle the value of the tool diameter of the inner pipe, wall thickness and the value of cylindrical deviation effect. In this paper a comparative analysis of the outer diameter, inside diameter and cylindrical deviation effect for physical and numerical studies. Simulation of reduce tubes was carried out with DEFORM 3D software based on the finite element method. Numerical analysis allowed for a detailed knowledge of the specifics of the process and a comprehensive analysis of phenomena that are not possible to explore traditional methods.
