A wire forming machine with a plurality of tools, a wire fed in a wire feeding direction including a supporting base, a main tool holder rotatably supported by the base holding one of the plurality of tools, a first control drive source configured to control a position of the main tool holder at an arbitrary rotation position; a holder supporting table rotatably supported by the supporting base, a second control drive source to control a position of the holder supporting table at an arbitrary rotation, a first sub tool holder rotatably supported by the holder supporting table about a first sub rotation axis, the sub tool holder holding one of the plurality of tools, and a first interlock mechanism including a gear group or a belt coupling interlockingly rotatably the sub tool holder to the main tool holder to transfer drive force of the first control drive source and holder.

A combined machine for working a wire rod in order to obtain metal products with at least a curved shape is disclosed that comprises a support bench configured to support and guide, along an axis of movement, a mobile slider comprising a work plane on which a curving unit is operative. The combined machine has vise means in the support bench. The slider also comprises, on the work plane, a bending unit associated with the curving unit and the vise means are positionable in a direction orthogonal to the axis of movement.

A clutch includes: a first clutch tooth that rotates integrally with a first rotation element included in a speed reducer; a second clutch tooth that rotates integrally with a second rotation element included in the speed reducer; and a fixed clutch tooth that moves between the first clutch tooth and the second clutch tooth. The fixed clutch tooth includes: a first mode in which the speed reducer operates at a second reduction ratio by meshing only with the first clutch tooth to fix the first rotation element, a second mode in which the speed reducer operates at a first reduction ratio by meshing only with the second clutch tooth to fix the second rotation element, and a both-engaging mode of meshing with each of the first clutch tooth and the second clutch tooth when changing a mode between the first mode and the second mode.

A tool for bending elongate objects including an electric motor having a motor output shaft, a bend mechanism having a support portion and a bias portion wherein first and second abutment portions of the support portion are separated by a space between them through which a third abutment portion provided by the bias portion can be moved in use. Force to be applied by the first, second and third abutment portions to an elongate object in use at different locations along the length of the elongate object for bending the elongate object, the third abutment portion having a plurality of bending surface portions each of which has a different radius of curvature and wherein the third abutment portion can be secured in different rotational positions thereby enabling a user to select the bending surface portion which engages the elongate object being bent in use.

Disclosed herein is a portable electric power tool for bending elongate objects. The tool includes an electric motor having a motor output shaft, a bend mechanism having a support portion and a bias portion. The bias portion is operatively coupled to the motor output shaft via a transmission of the tool which in use causes linear relative movement between the bias portion and the support portion. The relative movement causes force to be applied by the bend mechanism to an elongate object in use at different locations along the length of the elongate object for bending the elongate object. The transmission includes a conversion mechanism for converting torque into a linear force for causing the linear relative movement between the bias portion and the support portion.

Apparatus (10) for bending oblong metal products (100) comprising a movement device (17) of said products (100) and a first bending unit (18) configured to bend one or more of said products (100) at a time on a same first bending plane (P1).

A powered bending tool comprises a portable drive housing including a handle and having a powered drive gear. A bracket is secured to the housing defining a pivot connection spaced from the drive gear. A driven gear is pivotally connected to the bracket at the pivot connection and operatively engages the drive gear. A center guide is connected to the bracket at the pivot connection. A support is operatively connected to the bracket at one side of and spaced from the pivot connection. An arm has a near end pivotally connected to the bracket at the pivot connection and a distal end having an arm guide at another side of the pivot connection relative to the guide. The arm is selectively engeagable by the driven gear to be rotated therewith. In use, a rod is positioned below the center guide and above the arm guide and a support, and the drive gear drives the driven gear to pivot the arm so that the arm guide deforms the rod as it engages the center guide at a bend point.
