Abstract
A roll bender apparatus is disclosed for bending a work piece, the apparatus including a base, a bending roller rotatably disposed on the base, a first guide roller rotatably disposed on base. and a second guide roller rotatably disposed on the base. A first work piece guide assembly is movable about the first guide roller and a second work piece guide assembly movable about the second guide roller. The first and second work piece guide assemblies are oriented to receive the work piece, and the first and second work piece guide assemblies are configured to move about the first and second guide rollers respectively in response to the work piece being bent as the work piece is advanced between the bending roller and the first and second guide rollers.
Claims18
A roll bender apparatus for bending a work piece, the apparatus comprising:
- a base;
- a bending roller rotatably disposed on the base;
- a first guide roller rotatably disposed on base;
- a second guide roller rotatably disposed on the base, the first and second guide rollers positioned on opposite sides of the bending roller, wherein one or more of the bending roller, the first guide roller, and/or the second guide roller is translatable on the base to vary the bending of the work piece as the work piece is advanced between the bending roller and the first and second guide rollers;
- a first work piece guide assembly movable about the first guide roller;
- and
- a second work piece guide assembly movable about the second guide roller;
- wherein the first and second work piece guide assemblies are oriented to receive the work piece as the work piece is advanced between the bending roller and the first and second guide rollers, the first and second work piece guide assemblies configured to move about the first and second guide rollers respectively in response to the work piece being bent as the work piece is advanced between the bending roller and the first and second guide rollers;
- and
- wherein each work piece guide assemblies further comprises a guide assembly frame rotatable relative to the base, a first guide assembly roller rotatably disposed on the guide assembly frame and having a first rotational axis oriented in a first roller direction, and a second guide assembly roller rotatably disposed on the guide assembly frame and having a second rotational axis oriented in a second roller direction oriented at an angle to the first roller direction.

- a base;
- a bending roller rotatably disposed on the base;
- a first guide roller rotatably disposed on base;
- a second guide roller rotatably disposed on the base, the first and second guide rollers positioned on opposite sides of the bending roller, wherein the bending roller is translatable on the base in a direction extending between the first and second guide rollers, and one or more of the bending roller, the first guide roller, or the second guide roller is drivable to advance the work piece when the work piece is positioned between the bending roller and the first and second guide rollers, the bending roller being adjustable on the base to vary the bending of the work piece as the work piece is advanced between the bending roller and the first and second guide rollers;
- a first work piece guide assembly rotatably disposed about the first guide roller;
- and
- a second work piece guide assembly rotatably disposed about the second guide roller;
- wherein the first and second work piece guide assemblies are oriented to receive the work piece and resist twisting of the work piece as the work piece is advanced between the bending roller and the first and second guide rollers, and
- wherein each work piece guide assemblies further comprises a guide assembly frame rotatably mounted to the respective first or second axle, a first guide assembly roller rotatably disposed on the guide assembly frame and having a first rotational axis oriented in a first roller direction, and a second guide assembly roller rotatably disposed on the guide assembly frame and having a second rotational axis oriented in a second roller direction oriented at an angle to the first roller direction.

A roll bender apparatus for producing a curvature in a work piece, the apparatus comprising:
- a base;
- a first stationary guide roller and a second stationary guide roller, the first and second stationary guide rollers rotatable on the base;
- a bending roller, the bending roller movable on the base along a line of motion extending between the first guide roller and the second guide roller;
- a first guide assembly positioned adjacent to the first guide roller;
- and
- a second guide assembly positioned adjacent to the second guide roller;
- wherein each guide assembly is shaped to receive the work piece through the guide assembly and is movable about the corresponding guide roller to conform to changes in the curvature of the work piece as the work piece is bent during operation of the roll bender apparatus;
- and
- wherein each of the guide assemblies further comprises, a guide assembly frame movable about the corresponding guide roller, the guide assembly frame having a first end and second end, a first guide assembly roller rotatably disposed on the first end of the guide assembly frame and having a first rotational axis oriented in a first roller direction, a second guide assembly roller rotatably disposed on the guide assembly frame and having a second rotational axis oriented in a second roller direction oriented at an angle to the first roller direction.
