A bending head for welded wire mesh includes a frame, a bending face to be moved relative to the frame for bending a wire in a welded wire mesh, a counterholder on which the wire can be braced during bending by the bending face, a bending die which, at least in part, has a predefined bending radius, a bending arm on which the bending face is arranged, and an arm drive device with which the bending arm can be adjusted relative to the frame. A support is provided at and/or on which the bending arm is movably mounted. A support drive device, with which the support can be adjusted relative to the frame and which is separate from the arm drive device, is provided.

An automated bender and its method of operation according to some embodiments of the disclosure is provided. The automated bender includes a carousel which has all of the necessary components for bending a variety of conduit sizes provided thereon. The carousel can be rotated to a desired bending position to bend a particular type of conduit. A straight workpiece is fed into the automated bender and a bent workpiece, which may have multiple bends therein, is output from the automated bender. This bending process is performed without manual intervention. Software for achieving same is provided.

The present invention discloses a forming device for a large thin-walled part with a curved surface, which includes a punch, a blank holder, a die, a lower die plate, a first annular sleeve and second annular sleeves. The first annular sleeve is connected with first driving oil cylinders. An inner diameter of the die is greater than an outer diameter of the punch. The first annular sleeve is arranged in a gap between the punch and the die. The second annular sleeve is arranged at the bottom of the punch. The first annular sleeve is arranged outside the second annular sleeve. The second annular sleeve is connected with second driving oil cylinders. The first driving oil cylinders and the second driving oil cylinders are connected with a hydraulic system.

A method for manufacturing a continuous stirrup and an apparatus for implementing such method are provided. The method includes placing a planar structure formed of a wave-shaped rebar on a platform, fixing a side of the planar structure and using an elongated mold to abut against the other side of the planar structure to form an intermediate structure, flipping the intermediate structure, and abutting the elongated mold against the side of the planar structure to form a continuous stirrup.
