Abstract：

Aiming at the complex design of cold rolling tools，especially the difficulty of pass design，leading to the timeconsuming and laborintensive research and development process，a method of combining the parametric design with the pass design theory was proposed to simplify the pass design steps of rolling tools and improve the accuracy of the design results. On the basis of SMS MEER design method，the pass size was parameterized，the pass opening was selected and the parametric model was created. Then the Abaqus was further developed based on Python to create a 3D roller model. The finite element analysis was carried out on the rolling process of the rolling tools，and relevant parameters like rolling force，diameter and wall thickness were studied and the reasons were analyzed. The results show that the rolling force trend is in accordance with the theoretical basis，the maximum error value of diameter and wall thickness for the rolled titanium tube are 0.067 mm and 0.039 mm，which meets the precision requirements of rolled tube. The practicability and feasibility of this method are verified，the cycle and cost of R&D is shortened and saved.
