A machine for bending an elongated workpiece without wrinkling has a roller-like bending die (2) with a vice (3) adapted to retain one end of the elongated workpiece (P) to be bent. The roller-like bending die (2), being provided with a central hole (5) and a groove profile (6) and rotatable about a rotation axis (y), bears, centrally and coaxially in its groove profile (6), a plate element (18) oscillating with respect to the bending die (2) around a rotation axis (y) thereof. The plate element (18) having a peripheral edge (19) which continues the groove profile (6) of the bending die (2) consists of at least two pieces (20, 21) which are adapted to be connected to one another to surround the bending die (2).

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.

Tube bending devices for bending a tube. The tube bending devices include an actuator, a crank, a bending die, and a clamp assembly. The crank is mechanically coupled to the actuator. The bending die is mechanically coupled to the crank. The clamp assembly is operatively coupled to the bending die and configured to selectively secure the tube to the bending die. The actuator selectively drives the crank. The crank selectively rotates the bending die. The crank is configured to rotate the bending die over at least 180 degrees.

One aspect of the present disclosure is a manufacturing device by which the bent pipe is obtained by bending a double pipe. The device includes inner and intermediate core metals, a bending mold, and a controller. The controller executes: a first bending process in which first and second pipes are bent by the bending mold in a first direction in a first area of the double pipe where the inner and intermediate core metals are placed; a second bending process in which the first and second pipes are bent, after the first bending process, by the bending mold in a second direction in a second area of the double pipe where the inner and intermediate core metals are placed; and a first bending-back process in which the second pipe is bent, after the first bending process, in a direction opposite to the first direction in the first area.

The invention relates to a bending machine (M) for bending a workpiece (300), remarkable in that a clamping jaw (511) is supported by a clamping jaw holder (510) receiving at least two clamping jaws (511, 512) arranged back to back, the clamping jaw holder (510) being fastened to a shelf (513) guided and driven in translation on the bending arm (500), the support shelves (600) punctually receiving the clamping jaw holder (510) separated from the shelf (513) and to move it on either side of the bending axis transversely to the advance axis of the workpiece (300) to be bent, independently of the bending arm (500) so that the clamping jaw holder (510) can be fastened again to the shelf (513) once the bending arm (500) has been rotated 180 degrees. The invention also relates to a bending process.

A powered conduit bending tool is configured to bend conduit. The tool comprises a housing, a motor contained within the housing, and a battery removably coupled to the housing to provide power to the motor. An output shaft extends from the housing and is driven by the motor to rotate about an axis. A head is coupled to the output shaft for rotation therewith. The head includes a curved channel for receiving the conduit. A guide is coupled to the housing and supported opposite the curved channel of the head. The guide includes a latching handle movable between a closed position and an open position. The motor drives the head to rotate relative to the housing so that the curved channel and the guide cooperate to bend the pipe.
