A three-dimensionally shaped round metallic wire having a cross-section non-circular portion in a predetermined portion without performing additional processing and having specified dimensional accuracy and accuracy of form. In an intermediate step in which the round metallic wire is processed in a predetermined three-dimensional shape, a cross-section non-circular portion forming machine 20 which forms the cross-section non-circular portion having a non-circular cross-sectional shape in at least one position is included. At the time of bending, the cross-section non-circular portion is held by a wire holding portion of a bending machine 30, and the bending is performed in the predetermined three-dimensional shape. Holding the cross-section non-circular portion causes relative rotation between the cross-section non-circular portion and the wire holding portion to be suppressed as compared with a case of the cross-section circular shape. Accordingly, bending accuracy in the three-dimensional shape for the round metallic wire is improved.

A method for manufacturing in space a rigid structure having a lattice is disclosed. The method includes creating of at least two framework elements from a coil of metal strip or wire, and creating of the lattice by cold-connecting the framework elements.

To simplify a commissioning and parameter change in a 3D bending process of wires, a 3D bending device and a 3D bending method for bending a wire are provided. The wire is held by a first leg and a second leg and the legs are moved, via a first to third relative movement device, in a first to third relative movement with a first to third movement axis in order to change, in an adjustable manner independently of one another, torsion angles of the first and second legs and a distance between the central axes of the legs.

The present invention discloses a positioning apparatus for positioning a spring product fed from a spring coiling machine. The positioning apparatus includes a first guiding panel having a first guiding surface for guiding the spring product and the first guiding surface have a length and a width; and a plurality of first mechanical holding members arranged on the first guiding surface in a direction of the length of the first guiding surface for optionally supporting and holding a first part of the spring product.

A simplified wire bending machine is provided comprising a bending head with an integrated wire cutoff mechanism. The bending head comprises an inner portion, wherein the inner portion includes a wire bending channel; and an outer portion, wherein the outer portion includes a cutting edge and one or more bending pins. The outer portion is rotatable about the inner portion such that a bending pin is capable of bending a wire around the inner portion. Further, the outer portion is movable from a first position to a second position in which the cutting edge is configured to engage and shear a wire.

A tool holder configuration structure for spring making machine includes a flat base plate and three displacement mechanisms arranged on the front side in a triangle, each displacement mechanism including a first sliding tract set and a second sliding tract set arranged at right angles, and three tool holder panels each said tool holder panel including a base, a first tool holder located on one side of the base and two second tool holders obliquely disposed at two opposite lateral sides of the first tool holder. The tool holder panels are respectively coupled to the second sliding tract sets of the displacement mechanisms to keep the first tool holders adjacent to one another so that the moving distance of the tool holder panels can be minimized and a large number of tools can be installed in each tool holder panel.

A wire rod forming machine according to the present disclosure includes: a base plate including a vertical first basal surface on its front side; a quill projecting from the first basal surface; a wire rod guide hole penetrating through the quill; a wire rod feeding apparatus provided on a rear side of the base plate; a first XY table; an extending supporting part including a second basal surface perpendicular to the first basal surface; and a second XY table provided at the second basal surface of the extending supporting part. The first XY table includes a slide plate having a recessed part configured to receive the quill. The slide plate is provided with a plurality of apparatus fixing parts configured to fix a plurality of first tool shifting apparatuses arranged radially about the recessed part. The second XY table includes a second tool shifting apparatus.

System and method for automatically bending a surgical rod are provided. The system includes a linear movement device configured to axially feed the surgical rod, a rotational movement device configured to rotate the surgical rod as it is axially fed, and a bending device including a roller to impose bending forces against the rod. The rod is free from contact with the bending device after it is axially fed past the roller.

A device for bending wire includes a first plate with upper and lower surfaces and a center aperture extending therebetween. A cavity is formed in the upper surface that includes opposing sidewalls with a separation that decreases as they extend towards the center aperture and decreases as they extend up from a bottom surface of the cavity. A pin assembly disposed in the cavity includes a second plate having a pin extending from a top surface and having opposing side surfaces with a separation that decreases as they extend towards the center aperture and decreases as they extend up toward the top surface. A shaft extends through the center aperture and terminates in a bend head having a wire aperture and first and second bend surfaces adjacent the wire aperture. A first motor is configured to rotate the first plate about the shaft in opposing first and second rotational directions.
