Abstract: An angle indicator is provided for use with a pipe bender and is adapted to be removably mounted to a handle of a pipe bender. The angle indicator includes a plate; a first wheel rotatably mounted to the plate and including a plurality of angle indicating marks evenly spaced about a periphery of the first wheel; a second wheel rotatably mounted to the plate concentrically with the first wheel; the second wheel being smaller in diameter than the first wheel and including a mark at a periphery of the second wheel, the mark being selectively alignable with one of the angle indicating marks of said first wheel; a bubble level mounted on the second wheel; a first lock to hold the first wheel in a desired rotational position; and a second lock to hold the second wheel in a desired rotational position. The use of two wheels allows for zeroing of the angle indicator and dialing in of the desired angle.

Abstract: An angle detecting head provided with an emitter and a pair of receivers is rocked, and a bent surface of a workpiece bent by a punch and a die of a bending machine is irradiated with a measurement light from the emitter, a reflected light is received by the pair of receivers, and a bending angle of the workpiece is obtained from a peak value of the light received by the respective receivers. The angle detecting head is movable parallel to the die, is movable in a direction close to and away from the workpiece, and is movable in a direction in which the die is raised/lowered. The angle detecting head is positioned in an optimum angle measurement position of the workpiece and the bending angle is measured. Moreover, the bending machine presses the workpiece to the vicinity of a target angle, measures the bending angle of the workpiece during final pressing, removes pressure to bring the workpiece to an unloaded state, measures the bending angle of the workpiece, and obtains and stores a difference between the final pressing angle measured value and the unloaded angle measured value as a spring-back amount.

Abstract: A plastic conduit bender comprises an integrally molded handle and head portion. A steel hook reinforcement is molded directly into the head portion to provide sufficient force for bending the conduit. Steel reinforcements can also be provided in a grip region of the handle. A plurality of vertical sight lines, indicating bend angles, are provided from an apex molded into the handle and extending to an arcuate shoe portion, allowing the user to gauge the approximate bend angle. A flat surface including rounded saddle portions for receiving the conduit is positioned on the handle to allow the conduit to be bent back or straightened, the rounded saddle contact surfaces preventing damage to the conduit as it is bent back.

Abstract: A pipe bending tool is formed from a body and a pipe engaging hook. The body features a curved and convex base in which a longitudinal channel is formed. The channel features a first section, characterized by planar and preferably parallel side walls, and a deeper and adjacent second section, characterized by planar side walls, which preferably taper. The side walls of the second section preferably converge at a 90° angle to form a V-shaped channel base. This channel design permits pipes of more than one diameter to be bent in the same tool.
