Abstract
Device for the controlled and independent rocking of a bending platform and straightening platform in bending-shaping machines having an independent bending platform (13) located downstream of a straightening platform (11), in which machines the straightening platform (11) has a preferred inclination, whereas the bending platform (13) has an inclination depending on the product being processed at that time, the axis of rotation (17) for adjustment of the inclination of the bending platform (13) being positioned below and at a distance 'x' from the axis of the inlet (16) of rods (18) onto the bending platform (13), in which device the straightening platform (11) is supported on a parallelogram system (20) having the axis of lower pivots (26) distant by the value 'x' from the axis of upper pivots (25), the axis of the lower pivots (26) coinciding with the axis (17) of rotation of the bending platform (13), whereas the axis of upper pivots (25) is kept so as to coincide substantially with the axis of the inlet (16) of rods (18).
