Hydro-Forming a Cross-Shaped Component from Tube Billet

This paper investigates the tube hydroforming (THF) process through numerical simulations conducted in Abaqus/CAE software, aiming to identify optimal technological parameters for cross-shaped forming from seamless tube billets. The study focuses on seamless copper CDA110 tube billets as the primary material. The simulation evaluates critical factors such as thinning, thickening, and the height of the formed bulge. Output data is collected and analyzed using linear regression methods, followed by a comparison with technical requirements to assess suitability. The research results provide both scientific and practical foundations, contributing to the optimization of the cross-shaped hydroforming process while expanding the applicability of this technology in industrial production.
