Abstract
Provided is a wheel spinning die wherein the plurality of identical slide blocks are connected end to end to form a circular ring, and the slide blocks are inserted into an annular groove between the side wall of a circular groove at the upper end of the lower die and the central connecting block; during spinning, each arc flange is clamped at the joint of an outer wheel lip and a rim under a spoke; and during die releasing, the slide blocks can move up and down together with the vertical movement of a wheel blank, so that the problem of releasing of a reverse draft die at the joint of the cold spinning wheel rim and the outer wheel lip can be solved, wheel damage caused by die releasing can be eliminated, and the yield and production efficiency of wheels are improved.
