Abstract

Tube-bending machine with hydraulic drive, uses a single hydraulic cylinder which in the first part of its stroke actuates levers so a bending tool pushes the tube against the bending roller and, in the second part of the stroke, a bending arm is moved round the axis of the bending roller after a ratchet mechanism has feed the bending arm at the end of the first part of the stroke. The bending arm is pref. L-shaped and mounted on a pivot bearing at the end of one leg of the ''L'', the end of the other leg being connected by a lever to the piston in the hydraulic cylinder. A simple transportable machine mounted on a trolley, bends up to 100 degrees can be obtd. and the bending time is e.g. 10 seconds.
