Simulation and Prediction of Temperature Field in Drawing Process for Aluminum Circular Tube
The method of numerical analysis coupled thermal-mechanical effect during plastic forming was illustrated.A simulation model of drawing process based on heat coupling was set up,and two simulation plans,one with different drawing velocity in the range of 50～150 mm/s and another with different friction coefficient in the range of 0.02～0.4,was designed.According these two plans,the relationship between the maximum temperature of die and velocity of drawing,and the relationship between the maximum temperature of the die and the friction coefficient were gained.The results show that the maximum temperature of the die has a nearly linear increase with the increase of drawing velocity or the increase of friction coefficient.The simulation predictions of temperature field offer some references for the selection of anti-friction material and design of drawing process and die.
