This study employs the finite element analysis method to thoroughly investigate the stress-strain performance of cold header supports under different reinforcement rib lengths. Through a comparative analysis of simulation results with varying reinforcement rib lengths, it is found that as the rib length increases, the stiffness of the support is significantly enhanced, resulting in a substantial reduction in the maximum deformation and stress levels at the top. Specifically, when the reinforcement rib length is set to 140mm, the stress-strain performance of the support reaches its optimal state, effectively ensuring the stable operation of the cold header under high-speed and high-precision working conditions. Furthermore, for cases where the strength of the support is limited or cannot be changed, this study explores lightweight design strategies for the connecting rod of the cold header. While ensuring the structural strength of the connecting rod, a significant reduction in its mass is achieved through optimized design and material selection. Finite element analysis results show that the lightweight design effectively reduces the maximum stress concentration area of the connecting rod, significantly decreasing the potential risk of fatigue failure, thus extending its service life and improving its reliability. This study not only provides important references for the optimized design of cold header supports, but also offers new ideas and methods for the lightweight design of cold header connecting rods. These research outcomes are of great significance for enhancing the overall performance and stability of cold headers.
