초록 ▼

An apparatus is provided for forming a pulley having at least two grooves from a cup-shaped blank having an axially extending sidewall. The blank is crushed between axially closing dies and as the blank is being crushed, at least two rolls are translated radially into contact with the outer surface of the blank sidewall while the blank is rotated to form at least two annular pulley grooves in the sidewall of the blank. During such translation, a forming roll positioned between the axially closing dies and within the cup is radially shifted away from the longitudinal axis of the cup and into contact with the inner sidewall thereof to form a land between pulley groove pairs.

대표청구항 ▼

A machine for forming a pulley having a plurality of pulley grooves of given cross section from a pulley blank in the form of a cup, each groove being defined by pulley wall means connected through the root of the groove and each groove being separated from an adjacent groove by a land, comprising axially movable members for engaging said blank adjacent opposed axial ends thereof, means to axially advance at least one of said axially movable members toward the other to a final apposition at which they define a die cavity, first and second rotatably mounted roll die means, said first roll die means being translatable toward the longitudinal axis and the outer sidewall of the cup and having a periphery adapted to roll form the periphery of the blank to a desired configuration, said second roll die means being positioned between said axially movable members, being translatable away from the longitudinal axis and toward the inner sidewall of the cup, and having a periphery adapted to complement the periphery of the first roll die means and to roll form the periphery of the blank to said desired configuration, means to establish relative rotation between said pulley blank and said forming rolls, first roll die moving means to advance said first roll die means from a retracted position toward said longitudinal axis and to a final forming position at which it defines a die cavity corresponding to further portions of a desired configuration, second roll die moving means to advance said second roll die means away from said longitudinal axis toward said first roll die means to said final forming position at which it and said first roll die means together define said further portions of said desired configuration, said first and second roll die moving means being arranged to substantially simultaneously stop the advance of said first and second roll die means at said final forming position.
