<p>A straightening-bending plant or apparatus utilizing a universal straightening-bending machine, preferably associable with wire stock feeding means, in which the straightening-bending machine comprises in progressive order, on a pivotable working plane (B) about a horizontal axis (Y-Y): - advancing and straightening means (3) with opposed rolls to straighten and advance in longitudinal path said stock (b) laying on said working plane (B), associated/able with eventual guiding means (4); - cutting means (5'), laying on the same working plane (B), for cutting said stock material; - bending means (5) for bending said stock material by means of central anvil means (6) and bending nib, (7) rotating around; characterized in that the respective working plane pivoting means (2, 2') are conceived to orient said working plane (B): - from a first approximately horizontal position ( beta DEG =90 DEG ) - to a second positive inclined position (0 DEG < beta DEG <90 DEG ) in which the working plane faces frontally and upwards; - to a third vertical position ( beta DEG =0 DEG ) in which the the working plane faces frontally, - to a fourth negatively inclined position (0 DEG <- beta DEG <90 DEG ) in which the working plane faces frontally and downwards, and wherein: - the respective pivoting axis (Y-Y) of said working table (B) is displaced downwards in respect of the longitudinal stock material advancing path (X-X) when the working plane is oriented in said third vertical position and said fourth negatively inclined position.</p> |
