Abstract
An improved forged wheel trimming die, including a connecting rod, a lower die base lower plate, a bottom plate, a stripper guide pillar, a knockout rod, an ejector block, a lower die base stiffened plate, a lower die base upper plate, a lower die, a stripper plate, follow-up retainer plates, a shearing blade and a trimming rod. The improved forged wheel trimming die has the advantages that by adding two follow-up retainer plates to the stripper plate of the die, burrs of a forged wheel blank are constrained along the radial direction during the cutting, thereby avoiding breakage due to excessive deformation; in this way, the burrs can be protected from damage and knocked out successfully by the knockout rod after being cut off from the blank.
