<p>The article presents a comprehensive study of cold extrusion processes for hollow semi-finished products made of AISI 1015 steel, intended for further drawing with thinning. The finite element method was applied in the DEFORM environment using an elastic-plastic metal model. The results of traditional reverse extrusion and reverse extrusion with expansion in a movable die were considered and compared. The dependencies of the extrusion forces, the extraction of punches from deformed workpieces, and the ejection of semi-finished products from dies on the movement of tools were determined. The exact distributions of specific forces on punches, ejectors, and dies were established. The distributions of temperature, stress components, and deformations in the deformed metal of semi-finished products at the end of the extrusion processes were determined. The metal structure was evaluated by cold plastic deformation based on the distribution of deformation intensity. The results presented for the extrusion process with expansion in a movable die are new. When using a movable die, lower deformation forces and specific forces were obtained, as well as a more uniform and deeper processing of the metal structure, which has a positive effect on the mechanical properties of the semi-finished product. Based on the simulation results, an extrusion die was designed and manufactured, and experimental tests were conducted on a hydraulic press. A good match was found between the calculated and experimental data for the extrusion force. The study allows for the optimization of the manufacturing technology for precision semi-finished products and contributes to an increase in the service life of the forming tool.</p>
