Study of Different Parameters in Seamless Cold Drawing Process Using Finite Element Simulation

The application of steel tubes especially with close tolerances and good dimensional accuracy, in hydraulic cylinders for different applications makes in a point of interest for various designers. In this paper effect of different parameters like die entry angle, coefficient of friction and cross section reduction of the tube was studied with a 3D model of seamless cold drawing process using ABAQUS 6.10. Simulations were carried out with two sets of data, one comprising of different levels of die entry angle and cross section reduction and other set comprising of different levels of die entry angle and coefficient of friction. The effect of these parameter on process and material behavior was studied. Model was validated through the data obtained from the industry. The developed models have given important contribution to the understanding of how different parameters affect the drawing process. It also helps in determining the condition of failure. These models can further b used to carry out other process improvement studies and analysis..
