Abstract

This disclosure provides a tube shaping tool for a torque mechanism to modify a tube end. The tube shaping tool can include a cup and an internal assembly. The internal tube assembly can include a stem and an internal body. The stem can be received by the torque mechanism and transmit torque generated from the torque mechanism to the components of the tube shaping tool. The tube shaping tool can roll form the outside diameter of the tube end using standard bearings and a flange bearing attached to the internal body. The flange bearing can also include a flange that can provide facing of the tube end.

First claim

What is claimed is:

1. A tube shaping tool for a torque mechanism that provides a source of torque, the tube shaping tool comprising:
an internal body radially centered on a center axis that is longitudinal to the internal body, including
a stem extending from the internal body along the center axis and formed to be detachably engaged with the torque mechanism,
a body outward surface disposed along a radial perimeter of the internal body,
a body forward surface disposed opposite from the stem, extending inward from the body outward surface, and
internal fastener apertures extending from the body forward surface into the internal body;

a plurality of standard bearings disposed adjacent to the body forward surface, each of the plurality of standard bearings having
a bearing stationary portion, and
a bearing outward surface disposed radially opposite the bearing stationary portion with respect to each of the plurality of standard bearings, the bearing outward surface angled away from the center axis;

a flange bearing disposed adjacent to the body forward surface, having
a flange bearing stationary portion,
a flange bearing outward surface disposed radially opposite the bearing stationary portion with respect to the flange bearing, the flange bearing outward surface angled away from the center axis, and
a flange for facing a tube end extending outward from the flange bearing outward surface with respect to the flange bearing;

a tool bit disposed on the internal body, radially inward of the plurality of standard bearings and the flange bearing, the tool bit having
a tool bit shank disposed within the internal body,
tool bit flutes extending from the tool bit shank, and
a tool bit tip extending from the tool bit flutes; and

a plurality of fasteners connecting the plurality of standard bearings and the flange bearing to the body forward surface, the plurality of fasteners partially disposed in the internal fastener apertures.

2. The tube shaping tool of claim 1 , wherein the bearing outward surface and flange bearing outward surface are angled between 4 and 5 degrees with respect to the center axis.

3. The tube shaping tool of claim 2 , wherein the body forward surface is angled between 4 and 5 degrees with respect to a radial plane oriented 90 degrees from the center axis.

4. The tube shaping tool of claim 1 , wherein the bearing outward surface and flange bearing outward surface are perpendicular to the body forward surface.

5. The tube shaping tool of claim 1 , wherein the plurality of standard bearings comprise two bearings.

6. The tube shaping tool of claim 1 , wherein the plurality of standard bearings are ball bearings.

7. A tube shaping tool for shaping a tubing end, the tube shaping tool comprising:
a cup body portion radially centered on a center axis that is longitudinal to the tube shaping tool, having
a cup tube aperture disposed along an inward radial perimeter and formed to receive the tubing end, and
a cup internal aperture disposed outward from the cup tube aperture and oriented inward towards the center axis;

an internal body radially centered on the center axis, including
a body outward surface disposed inward of and adjacent to the cup internal aperture,
a body forward surface disposed within the cup body portion extending inward from the body outward surface, and
a body tool bit aperture extending from the internal body along the center axis;

a flange bearing disposed adjacent to the body forward surface, having
a flange bearing stationary portion,
a flange bearing outward surface disposed radially opposite the flange bearing stationary portion with respect to the flange bearing, the flange bearing outward surface angled away from the center axis, and
a flange extending outward from the flange bearing outward surface with respect to the flange bearing, the flange in contact with the cup internal aperture;

a plurality of standard bearings disposed adjacent to the body forward surface, having
a bearing stationary portion, and
a bearing outward surface radially opposite the bearing stationary portion with respect to each of the plurality of standard bearings, the bearing outward surface angled away from the center axis;

a plurality of fasteners connecting the flange bearing and the plurality of standard bearings to the internal body; and
a tool bit disposed radially inward of the body tool bit aperture, having
a tool bit shank disposed within the internal body,
tool bit flutes extending from the tool bit shank, and
a tool bit tip extending from the tool bit flutes.

8. The tube shaping tool of claim 7 , wherein the flange is formed to provide facing of the tubing end.

9. The tube shaping tool of claim 7 , wherein the plurality of standard bearings are positioned to roll form an outer diameter of the tubing end.

10. The tube shaping tool of claim 7 , wherein the tool bit shank is formed to remove burrs from the tubing end.

11. The tube shaping tool of claim 7 , wherein the tool bit shank is formed to create a bevel to the tubing end.

12. The tube shaping tool of claim 7 , wherein the plurality of standard bearings and the flange bearing are positioned to create a bevel to the tubing end.

13. The tube shaping tool of claim 7 , wherein the flange is shaped as an annulus.

14. The tube shaping tool of claim 13 , wherein the cup internal aperture includes cup cutouts shaped as an arc with a radius greater than an outer diameter of the flange.

15. A tube shaping tool to shape a tube with an outer diameter surface, an end face, and an inner diameter surface, the tube shaping tool comprising:
an internal body shaped as a cylinder with a longitudinal axis;
a standard bearing disposed on the internal body and arranged to roll form a bevel to the outer diameter surface of the tube;
a flange bearing disposed on the internal body and arranged to operate with the standard bearing to roll form a bevel to the outer diameter surface of the tube, the flange bearing including a flange extending outward from the flange bearing with respect to the flange bearing, the flange having an annulus shape and formed to provide facing to the end face of the tube;
a tool bit disposed on the internal body, arranged to bevel the inner diameter surface of the tube; and
a cup body portion shaped as a cylinder and formed to receive the internal body, having a cup tube aperture sized to receive the outer diameter surface of the tubing.

16. The tube shaping tool of claim 15 , wherein the internal body further comprises:
a stem extending from the internal body along the longitudinal axis of the internal body;
a body outward surface oriented outward and shaped as a cylinder;
a body forward surface extending inward from the body outward surface and angled greater than 90 degrees from the axis;
a body tool bit aperture extending from the body forward surface towards the stem, centered on the longitudinal axis of the internal body; and
a plurality of internal fastener apertures disposed outward from the body tool bit aperture and inward from the body outward surface, extending from the body forward surface towards the stem.

17. The tube shaping tool of claim 16 , wherein the bearing outward surface and the flange bearing outward surface are angled between 4 and 5 degrees with respect to the center axis.
