Definitions
- the present invention relates to a metallic wire and to a method for its manufacture.
- the invention can be used in industry, in particular for providing conveyor belts for applications in apparatuses that operate:
- conveyor belts are widespread in industry and are used in a myriad of environmental conditions that differ in terms of temperature, humidity and chemical agents that are present.
- wires and/or metal plates are used which are conveniently bent/deformed/coupled to define a plurality of links that substantially make up a mesh that forms the conveyance surface of the belt which, at a constant pitch, is articulated on pins called "rods", which effectively constitute the fulcrums of the consecutive hinges formed by the conveyor belt, essential elements for adhering to the rollers or other element for the entrainment and inversion of the conveyor belt.
- Such wires and plates are made of metallic alloys, generally steel, such as for example AISI 314 steel or AISI 310 steel.
- the wires or plates used, and therefore the conveyor belt are subject, with the passing of time, to degradation, which can determine deformations that no longer permit the function of the hinges, in addition to embrittlement, and this is due mainly to:
- the aim of the present invention is to provide a metallic wire and a method for its manufacture that are capable of avoiding the drawbacks of the known art in one or more of the above mentioned aspects.
- an object of the invention is to provide a metallic wire and a method for its manufacture that make it possible for the wire to be less subject to the phenomena of degradation that develop in particular at high or low temperatures, with respect to conventional wires.
- Another object of the invention is to provide a metallic wire and a method for its manufacture that result in a longer operating life of the conveyor belt, made starting from such wire, than that of similar, conventional conveyor belts.
- Another object of the invention is to provide a metallic wire and a method for its manufacture that enable the wire to produce less sliding friction than similar, conventional wires.
- a further object of the present invention is to overcome the drawbacks of the background art in a manner that is alternative to any existing solutions.
- Another object of the invention is to provide a metallic wire and a method for its manufacture that are highly reliable, easy to implement and of low cost.
- a metallic wire characterized in that it comprises, from the inside outward:
- a metallic wire according to the invention in a first embodiment, is generally designated by the reference numeral 10.
- wires that are circular in cross-section, but in variations of embodiment, not shown in the figures, the wires can have different shapes in cross-section, for example quadrangular, and can be substituted by bands or ribbons, from which optionally plates can subsequently be made.
- the wire 10 comprises at least:
- single-strand means that it is made of a single wire of conductive material.
- the filament 11 is made of a ferrous material and has a diameter in the order of 0.5-10 mm.
- the intermediate layer 12 is advantageously composed of silicides.
- the outer layer 13 is made of aluminum and has a thickness in the order of 2-5 ⁇ m.
- the filament 11 is substantially uniformly covered by the intermediate layer 12 and by the outer layer 13 covered by alumina 14.
- Figures 2a and 2b show, in cross-section, two semi-finished wires used to provide, via alumination, the wire 10, and are designated respectively with the reference numerals 1 and 2.
- the semi-finished wire 1 comprises the internal filament 11, made of ductile iron alloy, and a layer 15 of outer covering, made of copper, applied by copper-plating the filament 11.
- This copper-plating is carried out using techniques that are per se known, such as chemical or electrolytic copper-plating.
- the layer 15 of outer covering has a thickness of less than 1 ⁇ m and is adapted to enable the grip of the outer layer 13, made of aluminum, on the filament 11, made of ductile iron alloy, to which otherwise it would not be able to bond owing to the low chemical affinity of the elements of which they are constituted.
- Figure 2b shows another embodiment of a semi-finished wire, generally designated with the reference numeral 2.
- Such semi-finished wire 2 comprises:
- the filament 111 has a diameter in the order of 0.5-10 mm.
- the intermediate covering layer 116 has a thickness less than 1 ⁇ m and is a layer applied via nickel-plating on the filament 111.
- Such nickel-plating is carried out using techniques that are per se known, such as chemical or electrolytic nickel-plating, and is adapted to enable the grip of the outer covering layer 115, made of copper, on the filament 111, made of stainless steel, to which otherwise it would not be able to bond owing to the low chemical affinity of the elements of which they are constituted.
- the outer covering layer 115 is a layer applied using copper-plating to the intermediate covering layer 116.
- This copper-plating is carried out using techniques that are per se known, such as chemical or electrolytic copper-plating.
- Such layer 115 of outer covering has a thickness of less than 1 ⁇ m and is adapted to enable the grip of the outer layer 13, made of aluminum, on the filament 111, made of stainless steel, to which otherwise it would not be able to bond owing to the low chemical affinity of the elements of which they are constituted.
- the intermediate layer 12 composed of silicides, which develop during the manufacture of the wire 10, as illustrated below, is an excellent bonding agent between the outer layer 13 and the internal filament 11, 111.
- the alumina 14 results in less sliding friction than the friction that develops on similar, conventional wires, thus contributing to lengthening the operating life of the wire 10, according to the invention, with respect to such conventional wires.
- the invention also relates to a method for the manufacture of the wire 10, according to the invention, which is shown schematically in Figure 3 starting from a semi-finished wire 1 and similar to the method for providing the wire 10 starting from the semi-finished wire 2.
- Such method consists of:
- the step of drawing is not always necessary, and is carried out hot, at a temperature of approximately 650°C.
- the bath of aluminum and silicon alloy 17 is performed inside a tub 18 which allows the simultaneous and parallel immersion of multiple semi-finished wires 1, 2, which are unwound from spools and are made to slide inside the tub 18 and the bath of aluminum and silicon alloy 17.
- Such aluminum and silicon alloy 17 has a percentage by weight in the order of:
- the silicon of this alloy 17 makes it sufficiently fluid to fill even the smallest holes.
- the bonding forces are low in comparison to gravitational stresses, and this enables a micrometric deposit on the immersed surfaces without requiring drawing in order to remove the excess alloy 17 (in 80% of cases), if extraction from the alloy bath is done with an inclination in the order of 60°.
- the method for the manufacture of the semi-finished wire 1, 2, according to the invention can entail:
- the invention fully achieves the intended aim and objects by providing a metallic wire and a method for its manufacture that make it possible for the wire to be less subject to the phenomena of degradation that develop in particular at high or low temperatures, with respect to conventional wires.
