Benefits of technology
The invention provides a method to reduce deformation of the end face of a wheel blank by using troughs to disperse stress and eliminate high points, which reduces overall deformation and height differences between high and low points.
Problems solved by technology
In a wheel manufacturing process, the end face of a wheel blank is easily deformed mainly because a hub is non-uniformly cooled by a die in a casting process, and stress is produced after the blank is solidified, resulting in wavy deformation on the surface.
After water quenching or thermal treatment is carried out on the wheel blank, deformation of the various zones is inconsistent, and deformation amount of the end face is further increased.

Embodiment Construction
[0010]An 18-cun wheel type is selected, and a trough 1 is arranged at the junction of every two separate side dies on the blank rim end face of a cast blank, and four troughs 1 are arranged in total. The depth of the troughs 1 is 0.4 times the height of a locating lip, the upper ends of the troughs 1 are 4 cm wide, and the lower ends of the troughs 1 are 1 cm wide.
[0011]A 22-cun wheel type is selected, a trough 1 is arranged at the junction of every two separate side dies on the blank rim end face of the cast blank, a trough 1 is arranged in the middle of each single side die on the blank rim end face of the cast blank, and 8 troughs 1 are arranged in total. The depth of the troughs 1 is 0.8 time of the height of the locating lip, the upper ends of the troughs 1 are 3 cm wide, and the lower ends are 2 cm wide.

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.
Description
TECHNICAL FIELD[0001]The invention relates to the field of manufacturing of wheels, in particular to a wheel blank.BACKGROUND ART[0002]In a wheel manufacturing process, the end face of a wheel blank is easily deformed mainly because a hub is non-uniformly cooled by a die in a casting process, and stress is produced after the blank is solidified, resulting in wavy deformation on the surface. A wheel side die is generally composed of four separate dies, and analysis shows that relative height difference most easily occurs at the junction of two separate side dies and in the middle of each single separate side die. After water quenching or thermal treatment is carried out on the wheel blank, deformation of the various zones is inconsistent, and deformation amount of the end face is further increased.SUMMARY OF THE INVENTION[0003]The invention aims at providing a method for reducing deformation of the end face of a wheel blank.[0004]According to the technical scheme of the invention, a ...
