Abstract

A method, system, and apparatus for a part forming system. The part forming system comprises a field shaper having a cavity configured to receive a workpiece and a die. The field shaper has a number of dimensions based on being inserted into a main coil. The workpiece is bent to form a part with a desired shape when an electromagnetic field from the main coil is applied to the field shaper while the filed shaper is located within the main coil.

First claim

What is claimed is:

1 . A part forming system comprising:
a field shaper having a cavity configured to receive a workpiece and a die, wherein the field shaper has a number of dimensions based on being inserted into a main coil, and wherein the workpiece is bent to form a part with a desired shape when an electromagnetic field from the main coil is applied to the field shaper while the field shaper is located within the main coil.

2 . The part forming system of claim 1 further comprising:
an electromagnetic system having the main coil, wherein the main coil causes a compressive force on the workpiece on the die to form the part.

3 . The part forming system of claim 1 , wherein the field shaper has a first half and a second half, wherein the first half has a slot that receives the die and the second half has a shape that receives the workpiece placed on the die when the first half and the second half are joined to define the cavity.

4 . The part forming system of claim 1 , wherein the number of dimensions is selected based on a size of the main coil.

5 . The part forming system of claim 4 , wherein the number of dimensions is selected from at least one of a height of the field shaper, a length of the field shaper, a length of a forming area, and a height of the forming area.

6 . The part forming system of claim 1 , wherein the die is selected from a group of dies consisting of a joggle die, an offset joggle die, and a crush joggle die.

7 . The part forming system of claim 1 , wherein the electromagnetic field causes a magnetic pressure that forms joggle bends in the workpiece for the desired shape of the part.

8 . The part forming system of claim 1 , wherein the field shaper has a cylindrical shape.

9 . The part forming system of claim 1 , wherein the die is a joggle die and the part is a stringer for an aircraft.

10 . The part forming system of claim 1 , wherein the part is selected from one of a stringer, a fuselage stringer, an aircraft stringer, an intercostal, a hydraulic reservoir, a cleat, a duct, a shaped frame, and a shear tie.

11 . The part forming system of claim 1 , wherein the workpiece comprises at least one of a conductive material, a metal alloy, a nickel alloy, aluminum, steel, carbon steel, copper, brass, silver, iron, or titanium.

12 . A part forming system for forming joggle bends in a workpiece, the part forming system comprising:
a main coil; a joggle die; and a field shaper having a cavity configured to receive the workpiece and the joggle die, wherein the field shaper has a number of dimensions based on a number of dimensions of the main coil, and wherein the joggle bends are formed in the workpiece to form a part with a desired shape when an electromagnetic field from the main coil is applied to the field shaper while the field shaper is located within the main coil.

13 . The part forming system of claim 12 , wherein the field shaper has a first half and a second half, the first half has a slot that receives the joggle die, and the second half has a shape that receives the workpiece placed on the joggle die when the first half and the second half are joined to define the cavity.

14 . The part forming system of claim 12 , wherein the number of dimensions is selected based on a size of the main coil.

15 . The part forming system of claim 12 , wherein the joggle die is selected from a group of dies consisting of an offset joggle die and a crush joggle die.

16 . A method for forming a part, the method comprising:
placing a workpiece into a cavity of a field shaper; and applying an electromagnetic field to the field shaper from a main coil located around the field shaper, wherein the electromagnetic field causes a magnetic pressure that bends the workpiece on a die into a desired shape for the part.

17 . The method of claim 16 further comprising:
inserting the field shaper with the workpiece in the cavity into the main coil.

18 . The method of claim 16 , wherein the magnetic pressure is a compressive force on the workpiece that bends the workpiece into the desired shape for the part.

19 . The method of claim 16 , wherein the magnetic pressure forms joggle bends in the workpiece to form the part.

20 . The method of claim 16 , wherein the part is selected from one of a stringer, a fuselage stringer, an aircraft stringer, an intercostal, a hydraulic reservoir, a cleat, a duct, a shaped frame, and a shear tie.
