Press for mfg. motor vehicle track rods - where both rod ends are hot forged, followed by bending and oil quenching

摘要

Bars are made into track rods or aligning rods for motor vehicles. The bar is heated in a controlled atmos. and then fed into a press in which the complex shape is obtd. by bending; and the rod is held in its final shape while it is hardened using oil quenching; the oil is fed in a controlled amt. and at a controlled pressure onto the clamped rod. During press forming, the two ends of the bar are pref. die forged. The pref. press includes a driven traverse fitted with a detachable upper die and a cradle supporting the workpiece- initially a straight bar. A pair of forging dies is located on each side of the press, which is located above an oil tank from which oil is pumped to quench the finished part. Infrared sensors detect the bar and start the forming operations. This automatic machine with a single cycle replaces conventional machinery involving a sequence of separate operations and/or several machines.
