Abstract：

Rotary velocity of extrusion wheel is an important process parameter for large diameter cable aluminum sheath in the cladding process, which has a direct influence on the working life of the process tooling, product quality and production efficiency. Based on the double wheel vertical continuous cladding machine SSLB500，the continuous cladding process for Φ180 mm×4 mm large diameter cable aluminum sheath was numerical simulated by finite element method. The distributions of the velocity field, temperature field and stress field during forming process at the different extrusion wheel rotary velocities were analyzed, and the influence rule about the rotary velocity of extrusion wheel on the continuous cladding process of cable aluminum sheath was obtained. Based on the same die structure, the continuous cladding test was made at the speeds of 3 and 7 r·min-1 respectively. The experimental results are coincidence with that from numerical simulation. Thus, the finite element model is proved to be correct. The research result provides reference for choosing parameters of large diameter cable aluminum sheath during continuous cladding process.
