Abstract
In one aspect, a method for agile forming is provided (900). The method uses a minimally sized linear forming/bending system (100) that has advanced controls to be able to manufacture a wide variety of components. In another aspect a system (100) is provided for the manufacturing of metallic components by incremental bending metal. The system may use a plurality of pin stands (105) wherein one pin stand is used for shapes that have little change along one direction of the metallic component, two pin stands at some distance from one another may impose a twisting motion and may be used to control or are used to avoid twist of the metallic component, and three roll stands are used to produce curvature along the component.
Claims20
A method for the manufacturing of a metallic component comprising:
- receiving a desired design for a metallic component by a forming system, wherein the forming system comprises a plurality of stands, and each stand comprises a plurality of pins;
- receiving a sheet of metal by the forming system;
- determining a shape of the sheet of metal by the forming system;
- comparing the shape of the sheet of metal to the desired design by the forming system;
- adjusting at least some of the plurality of pins of the plurality of stands by the forming system based on the comparison;
- passing the sheet of metal through the plurality of pin stands to incrementally bend, or stretch the sheet of metal by at least some of the plurality of pins by the forming system;
- determining a revised shape of the sheet of metal by the forming system after the sheet of metal has passed through the plurality of pin stands;
- comparing the revised shape of the sheet of metal to the desired design by the forming system;
- readjusting at least some of the plurality of pins of the plurality of stands by the forming system based on the comparison;
- and
- passing the sheet of metal through the plurality of pin stands to incrementally bend the sheet of metal by at least some of the plurality of pins by the forming system.
A system for the manufacturing of a metallic component comprising:
- one or more processors;
- and
- a computer-readable medium with computer-executable instructions stored thereon that when executed by the one or more processors cause the system to:
- receive a desired design for a metallic component, wherein the system comprises a plurality of stands, and each stand comprises a plurality of pins;
- receive a sheet of metal;
- determine a shape of the sheet of metal;
- compare the shape of the sheet of metal to the desired design;
- adjust at least some of the plurality of pins of the plurality of stands based on the comparison;
- pass the sheet of metal through the plurality of pin stands to incrementally bend the sheet of metal by at least some of the plurality of pins;
- determine a revised shape of the sheet of metal after the sheet of metal has passed through the plurality of pin stands;
- compare the revised shape of the sheet of metal to the desired design;
- readjust at least some of the plurality of pins of the plurality of stands based on the comparison;
- and
- pass the sheet of metal through the plurality of pin stands to incrementally bend the sheet of metal by at least some of the plurality of pins.
