Abstract
Apparatus (10) for bending elongated metal products (100) comprising a feed device (13), which moves the products (100) along a feed axis (X) and a first bending unit (15) provided with one or more pins (20, 22), the latter distinct from each other and configured to bend one or more products (100) at a time at in correspondence with a determinate bending zone (BZ).

An apparatus (10) for bending elongated metal products (100) comprising a feed device (13), configured to move said metal products (100) along a feed axis (X), a first bending unit (15), configured to perform one or more bends on one or more of said metal products (100) at a time in correspondence with a determinate bending zone (BZ), and a storage area (16) disposed distanced from said bending zone (BZ) and configured to house, in a condition of inactivity, at least one distinct second bending unit (17), alternative to said first bending unit (15), wherein each of said bending units (15, 17) is provided with a central contrast pin (20, 21) of its own, and with a bending pin (22, 23) of its own which is radially distanced from and rotating with respect to the corresponding contrast pin (20, 21), wherein the apparatus further comprises an exchanger device (19) comprising at least one rotatable mandrel (25) configured to alternately support, in a determinate condition, said first bending unit (15) or said at least one distinct second bending unit (17), said exchanger device (19) being configured to move said first bending unit (15) or said at least one distinct second bending unit (17) horizontally along a direction of exchange (T) between said bending zone (BZ) and said storage area (16), wherein said storage area (16) is disposed in a fixed position laterally to said bending zone (BZ).
A method for bending elongated metal products (100) the method comprising:
- a feeding step, wherein a feed device (13) moves one or more of said metal products (100) at a time along a feed axis (X) forward or backward, a bending step, wherein a first bending unit (15) performs one or more bends on one or more metal products (100) in correspondence with a determinate bending zone (BZ), and at least one replacement step, wherein at least one distinct second bending unit (17), alternative to said first bending unit (15), and housed, in a condition of inactivity, in a storage area (16) disposed distanced from said bending zone (BZ), is replaced to said first bending unit (15) for performing one or more further bends on one or more metal products (100) in correspondence with said bending zone (BZ), wherein in said replacement step an exchanger device (19), having at least one rotatable mandrel (25) configured to alternately support, in a determinate condition, said first bending unit (15) or said at least one distinct second bending unit (17), places, by moving it horizontally along a direction of exchange (T), said first bending unit (15), or said at least one distinct second distinct bending unit (17), in alternating cooperation with said bending zone (BZ) and with said storage area (16), wherein said storage area (16) is disposed in a fixed position laterally to said bending zone (BZ).
