Abstract
Benders are disclosed relating to the convenient, accurate, and precise bending of tubing. Example benders include features such as a mandrel, adjustable mechanical stops, and scales having relatively high resolution along with significant distance from a central axis of the mandrel. Certain benders may include separate fine and coarse adjustments to bend angles and support mechanisms for controlling the bend plane angle.
Claims20
A bender comprising:
- a. a mandrel configured to bend tubing having an outer diameter that is less than 0.7 inches;
- b. a first adjustable mechanical stop arranged and configured to limit the bending of tubing around the mandrel in a first direction;
- c. a tubing contact component arranged and configured to rotate around the mandrel;
- d. a lever arranged and configured for manual operation of the tubing contact component;
- e. a multiple bend plane angle support arranged and configured to lock in place at various distances from the mandrel;
- and
- f. a first linear bearing;
- g. wherein the multiple bend plane angle support moves relative to the mandrel;
- and
- h. wherein the first linear bearing is arranged and configured to support the motion of the multiple bend plane angle support relative to the mandrel.

- f. wherein the incremental bend angle lock has a first incremental bend angle lock locked position limiting the adjustable bend angle mechanical stop to a first range of mechanical stop positions that includes a mechanical stop position at a 90° bend angle;
- and
- g. further comprising a fine adjustment component arranged and configured to adjust the position of the adjustable bend angle mechanical stop by at least 2° when the incremental bend angle lock is locked in the first incremental bend angle lock locked position.
