DEVICE FOR BENDING TUBES OR PROFILED SECTIONS WITH SYMMETRICAL STRUCTURE FOR TWO-WAY BENDING AND MACHINE EQUIPPED WITH SAME

摘要

the invention relates to a bending head, for example, a technique ofbending by winding tension, of the type comprising a set (a form ofbending - bit) rotates around an axis (a1), and aa tube or a flange (6) tightly against the form of bending atthe bending, characterized in that it comprises a single set (a form ofbending jaws) which can be positioned according to do one or the other of twothe initial positions of bending (p1) and (p2), symmetrical with respect to the axis.the tube so as to allow either from (p1) in a direction of bendingbending, starting from (p2) bending in the opposite direction. the displacementthe jaws on two linear direction (ox) and (oy) and its orientationoptimal compared to the roller system are obtained by an eccentric.
