At present， the design and manufacture of the domestic spline cold roll forming machine are mainly based on the experimental data， and theoretical studies are still insufficient. Taking the vertical spline cold roll forming machine for example， the design and analysis methods are studied. Based on the calculation of the forming force， the overall layout and machine tool body structure of vertical spline cold roll forming machine are given. According to the forming force data obtained by simulation as well as the working conditions and force analysis for the sliding table and screw， the key parts of the transmission system are designed. The static and dynamic characteristics of the machine tool are also analyzed by strength and modal analysis for the vertical spline cold roll forming machine.
