20160016216 | Drawing and Straightening Apparatus for Metal Wire, and Corresponding Drawing and Straightening Method - Apparatus for drawing and straightening at least a metal wire, comprising a drawing unit of the metal wire along a direction of advance which comprises a first motorized main roll, on part of the periphery of which first idle contrast rolls are disposed, with a smaller diameter than the first main roll. The apparatus also comprises a straightening only unit of the metal wire, independent from the drawing unit, disposed along the direction of advance and upstream of the drawing unit, the straightening only unit comprising a second idle main roll, on part of the periphery of which second idle contrast rolls are disposed, with a diameter smaller than the second main roll. | 01-21-2016 |
20120279274 | Apparatus for Bending Elongated Metal Elements, Such as Metal Bars, round Pieces or Wire, and Relative Bending Method - An apparatus and method for bending elongated metal elements comprising a bending station provided with a first contrasting pin, a bending support defining a first bending plane on which the elongated metal elements are positioned and advance, and a first bending pin mounted mobile around the first contrasting pin, in order to bend the elongated metal elements on the first bending plane in cooperation with the first contrasting pin. The bending station comprises a second contrasting pin mounted on the first bending pin, and a second bending pin disposed mobile with respect to a bending support in a slanting direction with respect to the bending plane, in order to bend the elongated metal elements in cooperation with the second contrasting pin on a second bending plane, angled with respect to the first bending plane. | 11-08-2012 |
20110210097 | MACHINE AND METHOD FOR FORMING A METAL MESH - A machine for forming at least a metal mesh comprising longitudinal wires and transverse wires, comprising at least a welding unit provided with a plurality of welders by means of which the longitudinal wires are welded to corresponding transverse wires, each of the welders comprising at least two electrodes, respectively upper and lower, selectively movable between a first feed position, in which at least a first electrode is distant from the transverse and longitudinal wires, and a second welding position, in which both the electrodes contact and weld the wires by means of a passage of current. The welding unit is electrically fed by a three-phase type system. | 09-01-2011 |
20110197645 | Drawing and/or Straightening Unit For Oblong Metal Products, Such as Bars, Round Pieces or Metal Wire - A drawing and/or straightening unit for feeding one or more oblong metal products to a machine for working the metal products. The drawing and/or straightening unit comprises a first driven roller on which at least one metal product to be fed is positioned longitudinally, and at least a second contrasting roller, opposite the first roller with respect to an axis of feed of the metal product, to keep the metal product correctly positioned with respect to the first roller during feed. The drawing and/or straightening unit comprises actuators operationally associated with the second roller, in order to move, at least in the initial positioning step, the second roller with respect to the first roller, in order to vary the distance between the second roller and the first roller. The actuators comprise a first linear actuator able to command the initial movement of approach of the second roller toward the first roller, and at least a second linear actuator able to command the selective and controlled movement of the second roller substantially continuously during the feed steps, and hence the contrast applied to the metal product, according to its actual sizes. | 08-18-2011 |
20110056349 | Apparatus to Feed and Shear Metal Bars, and Relative Method - An apparatus and method to feed and shear metal bars, comprising a shearing unit that shears the metal bars sequentially into segments of desired length, and an alignment and translation unit, which feeds the metal bars to the shearing unit, provided with butting member suitable to cooperate with the tail ends of the metal bars in order to align them longitudinally with respect to each other. The butting member comprises a magnetic portion facing toward the tail ends of the metal bars, and conformed so as to generate a magnetic or electromagnetic attraction force on the tail ends, so as to attract the metal bars to itself and to keep the relative tail ends substantially aligned and in contact with the butting member. | 03-10-2011 |
20110008143 | FEEDING DEVICE AND METHOD FOR BARS - A device and method to feed bars which picks-up and removes selectively from a bundle one bar in order to dispose the bar for use in an operating machine. The device including first magnetic members, which separate from the bundle an end segment of a plurality of bars and dispose the end segments of the plurality of bars on a plane distanced with respect to the bundle, and second magnetic members, which cooperate with the first magnetic members so as to pick-up at least one bar at a time from the plurality of bars and to prepare the bar for sending to the operating machine. The device also includes third magnetic members, which temporarily hold the bar or bars picked-up by the first magnetic members, forming substantially a pick-up plane, in an intermediate step, from which the second magnetic members selectively pick-up the bars to be sent to the machine. | 01-13-2011 |
