Hot Extrusion Process for Petroleum Drilling Rig's Connection Based on Deform
Adopting the finite element methods for rigidity visco-plasticity,the process of hot extrusion process for the petroleum drilling rig's connection was numerically stimulated.The whole shape process and force parameters curve were obtained and analyzed,which can provide foundation for the craft improvement of hot extrusion shape and the die's structure optimization,and successfully resolve three engineering practical problems,such as forge piece inadequate,forge piece's staying on the terrace die and terrace die's rupture.
