Abstract
A universal quench press is used for the precision quenching of gears, bearing rings, saw blades, slitting knives, cylindrical parts, flat parts, dished parts, and other articles. A set of quenching dies reduce or eliminate the distortions in size, roundness, taper, and flatness encountered in manufacturing processes prior to the press quenching process and/or operation. The press has a plurality of posts or tie-rods configured to distribute the forces of the applied loads uniformly. Provisions are made for a plurality of generally concentric rams with all of the rams powered by hydraulic or pnuematic cylinders or other force exerting device or devices to provide a uniform and evenly distributed force. An automatic quench media splash guard seals the quenching chamber during operation and requires absolutely no set-up or operating adjustments or changes. Two or more automatic doors provide complete access to the die area during set-up and/or allow two or more points for loading and/or unloading of workpieces and/or tooling. For ultimate accuracy, the lower die plate is stationary and provides a means of guiding the center ram, thus assuring concentricity. Graduated shims are added …
