021.019 MULTIPLE STATION TUBE BENDER ABSTRACT OF THE DISCLOSURE A multiple station tube bender includes a rotatable table upon a platform adapted for incremental rotary movements and for intermittent raising and lowering. The horizontally disposed support rod is adapted to axially mount a tubular workpiece to be bent. A radially extending rod support is mounted upon the table for journalling the rod and including a gear mechanism for variably rotating the support rod for angular orientation of the workpiece before bending. A series of spaced bending stations are arranged around the platform, each including a bending brake assembly at varying center distances from the table and adapted for successive and progressive forming of bends in the workpiece at spaced points along its length. After each bend, the table automatically elevates and rotates the workpiece in a horizontal plane to the next bending station and lowers the workpiece into registry with the bending brake. A gear mechanism upon the rod support effects automatic rotation of the workpiece to a predetermined angle for the next successive bend. The bendingbrakes at all bending stations are adapted to act simultaneously on an adjacent workpiece so that there is a continuous intermittent delivery of workpieces in final form at the final bending station during continuous intermittent rotary movements of the table.
