A bending apparatus has (a) a first manipulator which feeds a hollow metal blank of closed cross section in its lengthwise direction, (b) a second manipulator which supports a first support means disposed at a first position and a metal blank while feeding it, a heating means disposed at a second position downstream of the first position in the blank feed direction for heating all or part of the circumference of the blank, and a cooling means disposed at a third position downstream of the second position for cooling a portion of the heated blank, and (c) a third manipulator which constitutes a second support means disposed at a fourth position downstream of the third position in the feed direction of the blank and which moves two-dimensionally or three-dimensionally while supporting at least one location of the metal blank to bend the metal blank into a desired shape.

A tube bending tool (1) comprising support surfaces (2, 2, 2), between said surfaces a tube (3), to be bent, is placed. A pressure exerting unit (6) with an extension (8) displaceable towards the tube (3), where a convex, bent bearing surface (10) is provided in order to press against the tube (3) when said extension (8) delivers a force from the pressure exerting unit (6). The front portion (9) comprises elongated elements (12, 12). The outer ends of the elongated elements (12, 12) comprise displaceable and movable support elements which press on the outer surface of the tube. The inner ends (13, 13) of the elongated elements are cross-laid and movable, so that they during bending, press in a direction towards the center of the bending radius of the tube (3), at the same time as different radii of the bend (5) can be provided on different places. There is also an optional limiting means for bends over 90 degrees.

A lift conduit bender handle for use with a conduit bender for bending a workpiece is disclosed. The lift conduit bender handle includes a bracket having two plates in quadrant configuration facing each other. Each plate includes holes. Further, the lift conduit bender handle inserts through the bracket and connects to the holes with the help of handrails while being positioned at a desired angle. The handle further includes a handle bracket. The handle bracket includes a set screw for tightening the handle. The handle connects to a bender head of a conduit bender. The bender head includes a conduit-receiving groove for receiving a workpiece or conduit or pipe. The lift conduit bender handle applies force on the workpiece around the bender head such that the workpiece gets sandwiched and the workpiece is forced to take the shape of the conduit-receiving groove.

A portable tubing bender configured to automatically bend a portion of tubing according to a defined set of bend specifications, including a desired number of bends and a desired angle for each bend. The portable tubing bender including a driver configured to rotate a driven shaft and a first rotational output, a reductive gear set operably coupling the driven shaft to an output shaft, a bender shoe couplable to the output shaft, the bender shoe defining an arcuate channel configured to receive tubing during bending operations, and an automatic feed mechanism configured to advance the tubing relative to the bender shoe from an initial position to a bend position.

Provided is a manual pipe bending apparatus having improved bending work convenience, the apparatus having an external gear formed on an outer peripheral surface of a bending shoe and having an operating ratchet engaging therewith, so that, when a worker rotates an operating lever to bend a pipe, rotation work, of the worker, for pushing or raising the operating lever is convenient and, when the operating lever is pushed once, the bending shoe can be rotated at a predetermined angle, thereby enabling the pipe to be bent uniformly at a predetermined degree, and thus easy bending work and a uniform bending angle can be expected. Between the operating parts, the operating ratchet which is rotated by a third rotating shaft and which has an end portion engaging with the external gear and an elastic means for applying elastic force to the operating ratchet are provided.
