Influence of Forming Velocity on Service Performance of Resistance Wall Structural Die
A crankshaft pre-forging with the resistance wall structural die is analyzed by the finite element method.The influence of forming velocity on the filling capacity,the maximum forming load,die surface temperature and wear depth is discussed.The results show that the values of the maximum forming load,die surface temperature and wear depth increase,while the minimum unfilled distance decreases as the forming velocity increases.It is found that increasing the value of forming velocity is benefit for improving the filling capacity.However,excessive forming velocity increasement may results in poor service life of tools.When die wear,production efficiency and cost be considered,it is indicated that the range of the forming velocity is 10-100 mm/s,the process has the optimal service performance.The analysis and conclusions in this paper are helpful in developing the technology specification of newly developed resistance wall structural die.
