Abstract

1378508 Rolling FORMFLO Ltd 2 Oct 1972 [7 Oct 1971] 46833/71 Heading B3M A cylindrical workpiece of constant diametral size is produced by rolling a cylindrical workpiece between at least two forming rolls 12, 14 whose innermost advanced position or the dwell time in the advanced position is varied in dependence on the variation of the workpiece dimensions from the dimensions of a nominal workpiece which would produce the desired final workpiece dimensions under standard roll advancement extent and dwell time. The rolls 12, 14 are mounted in yokes 16 operated by hydraulic piston-cylinder units 20. In one embodiment the extent of roll advancement of each roll is varied by a screwed adjustable stop 36 operated by a stepping motor 44 driven manually or by a device 40 which measures the workpiece size and computes the volume variation from the nominal size of workpiece. In an alternative embodiment the device 40 computes an appropriate dwell time from the volume variation. The dwell time is controlled by a pressure sensitive switch 50 and a timer 52 preset by the device 40.
