The action of curving a section into a segment or a circle is frequently achieved as a continuation of the roll forming process. The rollforming machine is extended to incorporate the 3 roll (or 2 roll and ‘shoe’) curving tooling following on from the rollforming action. A hand wheel with digital indicator allows for repeatability of adjustable product radius.
Additional features are frequently incorporated for automatic cut-to-length from coil and finished product ejection utilising PLC control.
CYLINDER ROLLING
Our 2 roll bending machinery forms virtually ‘Flat Free’ cylinders or segments from flat blanks in one pass. It is ideal for volume production of cylinders of known diameter. A steel mandrel and ‘urethane’ tyred roller are forced together by hydraulic pressure and the blank passed between. The blank is forced to follow the mandrel, producing a cylinder a fixed amount larger than the mandrel. A mandrel sleeve is required for each cylinder diameter to be rolled.
The latched top roller hinges out for cylinder removal, which can be automated along with the blank feed for continuous production.
