摘要： A method for reducing deformation of the end face of a wheel blank, a trough is arranged at the junction of every two separate side dies on the blank rim end face of a cast blank, a trough is arranged in the middle of each single side die on the blank rim end face of the cast blank, 8 troughs are arranged in total, the depth of the troughs is 0.1-1 times the height of a locating lip, the lower limit of the width of the upper ends of the troughs is the height of the locating lip, the upper limit is 1/16 of the circumference of the wheel blank, the lower limit of the width of the lower ends of the troughs 1 is 0, and the upper limit is 1/16 of the circumference of the wheel blank.
