Abstract
Machine for bending metal products (B) comprising a drawing unit (11) configured to feed at least one metal product (B) along an axis of feed (D) and toward a bending unit (12) and a shearing unit (14) configured to shear the metal product (B). The bending unit (12) is mounted on a translating platform (13) able to be translated in a direction of translation (T) transverse to the axis of feed (D), and at least one part of the shearing unit (14) is mounted on the translating platform.

A machine for bending metal products, the machine comprising:
- a bending unit;
- a drawing unit configured to feed at least one metal product along an axis of feed and toward said bending unit;
- and
- a shearing unit configured to shear said at least one metal product,
- said bending unit being mounted on a translating platform able to be translated in a direction of translation transverse to said axis of feed,
- said bending unit comprises:
- a rotating mandrel, wherein said rotating mandrel is disc shaped,
- a bending pin disposed on a periphery of said rotating mandrel, and
- a contrast pin disposed at a center of rotation of said rotating mandrel,
- when in operation, a rotation of said rotating mandrel rotates the bending pin to bend the at least one metal product around said contrast pin, and when the rotating mandrel rotates to bend the bars around the contrasting pin the shearing unit is kept in its inactive position,
- wherein at least one part of said shearing unit is mounted on said translating platform.
A method for bending metal products, the method comprising:
- feeding at least one metal product along an axis of feed to carry out at least one bending operation;
- bending the at least one metal product by a bending unit mounted on a translating platform;
- translating the at least one metal product by translating said translating platform in a direction of translation transverse to said axis of feed;
- and
- shearing the at least one metal product by a shearing unit,
- wherein said translating of said translating platform in said direction of translation brings at least a part of said shearing unit in cooperation with said metal product, said at least one part of said shearing unit being mounted on said translating platform, and when the rotating mandrel rotates to bend the bars around the contrasting pin the shearing unit is kept in its inactive position.
