Abstract:
A numerically controlled machine for curving, forming, folding and bending a bar, comprising:a bed coupled with a rotary bending head for obtaining folds in various planes; a folding snout carried by the bed, for receiving the bar for horizontal movement along a line of travel passing through the folding snout, and for forming bends in the bar, wherein the folding snout is mounted for translational movement along the line of travel; a turner associated with the rotary bending head and including a bending roller and a folding pin, wherein the turner is mounted in the rotary bending head for rotation in a plane and about an axis of rotation which is aligned with an axis defined by the bending roller; and a transverse carriage receiving the turner, wherein the transverse carriage is movable along a carriage axis which forms a right angle with the line of travel, for moving the turner along the carriage axis at a right angle to the line of travel; wherein the folding snout is continuously movable between forward bending positions in which the snout is near the bending roller and retracted positions toward an upstream end of the machine, and wherein a bending region defined between the turner and the bed is totally free.
