【正文】 es the classification of the bending machine, working principle and development in China. Through the demonstration of the mon types of institutions and the task book , having chosen this three roller coiling machine. By the analysis of the entire coiling movement, it could be divided into the main and the auxiliary movement. After determining the drive system program of the main and the auxiliary movement , then calculating the power of working bodies and motion parameters, reaching the model of motor .And select the type of transmission system , materials and heat treatment , design calculations and check. Design and check the materials and size, shaft, bearings, couplings and key design calculations, the final rack design. Key words： The three roller coiling machine Parameter design Check 皖西學(xué)院本科畢業(yè)論文（設(shè)計(jì)） 目 錄 1 緒論
