Method for reducing deformation of end face of wheel blank

Abstract

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.

1 . A method for reducing deformation of an end face of a wheel blank, comprising:
 arranging a trough at a junction of every two separate side dies on a 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, and at least one troughs are arranged in total as the wheel side die is composed of at least four separate dies, the depth of the troughs is 0.1-1 time 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 and the upper limit is 1/16 of the circumference of the wheel blank, and the lower limit of the width of the lower ends of the troughs is 0 and the upper limit is 1/16 of the circumference of the wheel blank.   
     
     
         2 . The method for reducing the deformation of the end face of the wheel blank according to  claim 1 , wherein a trough is arranged at the junction of every two separate side dies on the blank rim end face of the cast blank, and 4 troughs are arranged in total. A depth of the troughs is 0.4 times a height of the locating lip, the upper ends of the troughs are 4 cm wide, and the lower ends of the troughs are 1 cm wide. 
     
     
         3 . The method for reducing the deformation of the end face of the wheel blank according to  claim 1 , wherein a trough is arranged in the middle of each single separate side die on the blank rim end face of the cast blank, and at least 8 troughs are arranged in total, the depth of the troughs is 0.8 times the height of the locating lip, the upper ends of the troughs are 3 cm wide, and the lower ends are 2 cm wide.
