Abstract
A machine for bending or cambering a profile has two bending rollers mounted on a tool holder carriage, a block for supporting the tool holder carriage with respect to which the latter is pivotably mounted about a rotational axis coaxial with the axis of one of the bending rollers, the supporting block being pivotably mounted with respect to the frame of the machine about a rotational axis coaxial with the axis of the other bending roller; with the ability to rotationally lock either the tool carriage holder to the supporting block or the supporting block to the frame, and the ability to pivot in reverse directions the tool holder carriage/supporting block assembly or the tool holder carriage.
Claims15
A machine for bending or cambering a profile such as a rod, bar, tube, or wire, comprising:
- a frame on which are mounted bending means, and means for moving the profile longitudinally relative to said frame, wherein the bending means of said bending machine comprises:
- two bending rollers mounted on a tool holder carriage and provided with supporting surfaces between which the profile to be bent is passed, gripped, and rolled;
- a supporting block for the tool holder carriage, wherein said tool holder carriage is pivotably mounted about an axis of rotation coaxial with an axis of one of the two bending rollers, said supporting block being pivotably mounted with respect to the frame of the machine about an axis of rotation coaxial with the axis of one of said two bending rollers;
- an indexing means to lock in rotation either the tool holder to the supporting block in a left hand bending state, or to lock the supporting block to the frame in a right hand bending state;
- and
- a rotational drive means to pivot the tool holder carriage and the supporting block together as an assembly in a first direction of rotation in the left hand bending state of the indexing means, and to pivot the tool holder carriage in a second direction of rotation opposite to the first direction of rotation in the right hand bending state of the indexing means.
A bending head mountable in a detachable manner on a frame of a bending machine, said bending head comprising:
- two bending rollers mounted on a tool holder carriage and provided with supporting surfaces between which the profile to be bent is passed, gripped, and rolled;
- a supporting block for the tool holder carriage, wherein said tool holder carriage is pivotably mounted about an axis of rotation coaxial with the axis of one of the two bending rollers, said supporting block being pivotably mounted about an axis of rotation coaxial with the axis of the other of the two bending rollers inside a clevis-shaped part which can be secured in a detachable manner to the frame of the machine;
- an indexing means to lock in rotation either the tool holder to the supporting block in a left hand bending state, or to lock the supporting block and the clevis-shaped part, in a right hand bending state;
- and
- a rotational drive means to pivot the tool holder carriage and the supporting block together as an assembly in a first direction of rotation in the left hand bending state of the indexing means, and to pivot the tool holder carriage in a second direction of rotation opposite to the first direction of rotation in the right hand bending state of the indexing means.
