    摘要: A binder assembly for stamping sheet material includes an upper die, a stationary punch, an outer ring, and an inner ring. The stationary punch is aligned to be received inside a cavity of the upper die. The outer ring and the inner ring extend around the punch and are movable relative thereto. The inner ring includes teeth on a top surface and is positioned an initial distance from an end of the punch. The upper die is driven along the punch the initial distance such that the punch is received inside the cavity of the upper die a partial distance and a remaining distance such that the punch is received inside the cavity of the upper die a deeper distance.
