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.

Abstract: A spinning roller surface laser reinforced processing forming method is provided. A spinning roller is normalized after forging, the normalizing temperature is controlled to 860-880 DEG C., and the heat preservation time is 40-60 minutes; the spinning roller forging blank is roughly processed to reserve a tolerance allowance of 0.5 mm on the designated working face; the spinning roller and workpiece contact surface reinforcing layer is made of Ni625+WC2, in which WC is more than 22%; a reinforcing layer having the thickness of 0.8 mm is clad with laser on the working face of the spinning roller, and the preheating temperature is controlled to 250-400 DEG C. before welding; the spinning roller laser clad reinforcing layer is rolled; and the rolled spinning roller is put into a thermal treatment furnace for thermal treatment, and quenching and tempering treatment, re-crystallization and residual stress elimination are performed.

Abstract: The present disclosure discloses a method for forming a rim of a cast-spun aluminum alloy hub, that is, a special spinning composite machining method for forming a structure that the spokes and the inner wheel flange of the hub are cast and the middle of the rim is spun. The method can prevent the performance, strength and as-cast structure of the inner wheel flange from being destroyed, effectively improve the impact resistance of the cast-spun hub at the inner wheel flange, prevent the inner wheel flange of the cast-spun hub from cracking during radial impact and improve the performance of the spun structure of the rim, is beneficial to thinning the rim and realizes light weight of the rim.
