Abstract

The disclosed forming apparatus includes a frame. The frame defines a vertical axis, a horizontal axis, and a longitudinal axis. A carriage is movably connected to the frame. A first stomp foot is movably connected to the carriage such that it may move along the vertical axis. A first end effector is movably connected to the carriage. The first end effector is controlled by an actuator. The disclosed method for forming a composite part includes applying at least one ply of composite material over a forming surface of a forming tool and deforming the at least one ply of composite material over the forming surface of the forming tool with a forming apparatus.

First claim

What is claimed is:

1. A forming apparatus comprising:
a frame defining a vertical axis, a horizontal axis, and a longitudinal axis;
a carriage movably connected to the frame;
a first stomp foot movably connected to the carriage;
a first end effector movably connected to the carriage, said first end effector controlled by an actuator;
a second end effector movably connected to the carriage, said second end effector is laterally opposed from said first end effector relative to the longitudinal axis;
a second stomp foot movably connected to the carriage, said second stomp foot located laterally between the first stomp foot and the second end effector, wherein the first stomp foot is laterally adjacent to the first end effector; and
a ply support feature located below the first stomp foot and the second stomp foot;
wherein the first end effector comprises a first inflatable bladder and a first jacking screw and the second end effector comprises a second inflatable bladder and a second jacking screw;
wherein the first jacking screw manipulates the first inflatable bladder, and the second jacking screw manipulates the second inflatable bladder;
wherein a first radius of the first inflatable bladder and a second radius of the second inflatable bladder are independently manipulated by the first jacking screw and the second jacking screw.

2. The forming apparatus of claim 1 wherein the first end effector and the second end effector are configured to skew along the vertical axis.

3. The forming apparatus of claim 1 wherein the first end effector comprises a sensor configured to detect a forming tool.

4. The forming apparatus of claim 1 wherein the second end effector comprises a sensor configured to detect a forming tool.

5. The forming apparatus of claim 1 comprising at least one magnetic switch coupled with the first stomp foot wherein the at least one magnetic switch is configured to detect stomp foot movement.

6. The forming apparatus of claim 1 wherein the first end effector and the second end effector are configured to independently move laterally relative to the longitudinal axis.

7. The forming apparatus of claim 1 comprising a first plurality of the first end effector extending along the longitudinal axis and a second plurality of the second end effector extending along the longitudinal axis and laterally opposed from the first plurality;
wherein each first end effector of the first plurality is independently movable such that the first plurality may form a convex, concave, or linear configuration.

8. The forming apparatus of claim 1 wherein the carriage is configured to move along the vertical axis and the horizontal axis to match a forming tool orientation.

9. The forming apparatus of claim 1 comprising a protective slip film, wherein the protective slip film is connected to at least one retractable spool.

10. The forming apparatus of claim 1 wherein the first stomp foot and the second stomp foot are configured to move along the vertical axis and apply compaction force.

11. The forming apparatus of claim 1 wherein the first stomp foot is configured to pivotably move along the horizontal axis.

12. The forming apparatus of claim 1 wherein the independent adjustments of the first radius of the first inflatable bladder and of the second radius of the second inflatable bladder allow for independent conformity of the first end effector and the second end effector to a forming tool associated with the forming apparatus.

13. The forming apparatus of claim 1 wherein the first end effector and the second end effector are adjustable in a yaw angle to the longitudinal axis, the forming apparatus further comprising:
a first pivoting bearing assembly connected to the carriage and operatively coupled to the first end effector to allow adjustments in the yaw angle of the first end effector to the longitudinal axis; and
a second pivoting bearing assembly connected to the carriage and operatively coupled to the second end effector to allow adjustments in the yaw angle of the second end effector to the longitudinal axis;
wherein the adjustments in the yaw angle of the first end effector and the second end effector allow for uniform application of a compaction force across a forming tool associated with the forming apparatus.

14. The forming apparatus of claim 1 wherein the first jacking screw manipulates the first inflatable bladder to conform to concave or convex profiles and to control the first radius of the first inflatable bladder and the second jacking screw manipulates the second inflatable bladder to conform to concave or convex profiles and to control the second radius of the second inflatable bladder.

15. A system comprising:
a forming apparatus comprising:
a frame defining a vertical axis, a horizontal axis, and a longitudinal axis;
a carriage movably connected to the frame;
a first end effector movably connected to the carriage, said first end effector controlled by an actuator;
a second end effector movably connected to the carriage, said second end effector is laterally opposed from said first end effector relative to the longitudinal axis;
a first stomp foot movably connected to the carriage, said first stomp foot laterally adjacent to the first end effector;
a second stomp foot movably connected to the carriage, said second stomp foot located laterally between the first stomp foot and the second end effector; and
a ply support feature located below the first stomp foot and the second stomp foot;

a forming tool; and
at least one ply of composite material;
wherein the first end effector comprises a first inflatable bladder and a first jacking screw and the second end effector comprises a second inflatable bladder and a second jacking screw;
wherein the first jacking screw manipulates the first inflatable bladder to conform to concave or convex profiles and to control a first radius of the first inflatable bladder and the second jacking screw manipulates the second inflatable bladder to conform to concave or convex profiles and to control a second radius of the second inflatable bladder;
wherein the first radius of the first inflatable bladder and the second radius of the second inflatable bladder are independently manipulated.

16. A composite manufacturing system for fabricating a composite part, the composite manufacturing system comprising:
a ply carrier comprising a ply support surface configured to support at least one ply of composite material;
a carrier transfer device configured to convey the ply carrier;
a lamination system configured to selectively apply the at least one ply of composite material to the ply support surface of the ply carrier;
a transfer system configured to remove the ply carrier from the carrier transfer device and to apply the at least one ply of composite material to at least a portion of a forming surface of a forming tool; and
a forming system configured to form the at least one ply of composite material over the at least a portion of the forming surface of the forming tool, the forming system comprises:
the forming apparatus of claim 1 .

17. A manufacturing method of fabricating a composite part, the manufacturing method comprising steps of:
conveying a ply carrier to a lamination system using a carrier transfer device;
selectively applying at least one ply of composite material to a ply support surface of the ply carrier using the lamination system;
