Abstract：
|
|
The characteristics and application for designing the die flash groove of hot die forging were investigated.The effect on die service life of hot forging and product quality was analyzed.Through the design vector experimental analyses of the flash groove for hot die forging,an optimized design plan was put forward,in which the ratio of the flash groove depth to the bridge width is 1∶3.2,i.e.,F=H/3.2.The experiment result indicates that a good practice effect can be achieved by applying the optimized design plan.
