A pulley is disclosed. The disclosure provides a pulley. The pulley is made up of a frame and a wheel. The frame includes a first and second plate spaced apart from each other. The wheel is rotatably connected between the first and second plate. The first and second plate each include an extended portion extending in a common direction beyond the radius of the wheel. The extended portion of the first and second plate each include a ramp for guiding a line onto the wheel. Also disclosed is a method for making the pulley.

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.
