Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a metallic wire for spinning machines, which has good abrasion resistance and corrosion resistance and is used for spinning machines such as carding machines and air spinning machines.

BACKGROUND OF THE INVENTION Conventional metallic wires for spinning machines generally use hard steel wires or alloy steel wires, and since the tips of the metallic wires interact with fibers and wear out, they are processed to a higher degree of hardness by conventional methods such as heat treatment.

However, the harsh operating conditions in today's textile mills require even higher wear resistance, which is why special wear-resistant steels are used to achieve higher hardness. However, there are disadvantages in that the toughness of the teeth is reduced, the teeth are easily chipped, and it is difficult to wrap the metallic wire around the roller.

Figure 4, Figure 4! As shown in 1lllK, there are nine types of teeth that have highly wear-resistant eyebrows made by thermally spraying ultra-hard metal on the sides of the teeth. In this case, although the hardness of the wear-resistant layer is high, the surface is rough, and the fibers are concentrated in the recesses on the surface, causing the fIR#l to break and accelerate the wear of the metallic wire. .

Furthermore, when spinning flame-retardant fibers, there is a drawback that the metallic wires rust, making spinning impossible.

The present invention solves the drawbacks of the conventional metallic wire for spinning machines mentioned above.

Metallic wires for spinning machines made of nonferrous metals such as copper, zinc, and their alloys are coated with oxides on at least the tooth surface of the metallic wires by CVD, PVD, thermal spraying, plating, coating, etc.

Forms a ceramic layer of carbide, nitride, etc. to provide wear resistance,
The object of the present invention is to provide a metallic wire for a spinning machine that contributes to improved corrosion resistance.

An embodiment of the present invention will be described below based on drawings.

Embodiment 1 A take-in wire used in a carding machine according to an embodiment of the present invention is shown in FIGS.

A wire made of non-ferrous metals such as aluminum, iron, zinc and alloys thereof is punched out to form teeth (!) as shown in FIG. 1, and then A1.O.

A paint made by mixing a raw material containing gold as a main component and a binder is applied to the surface of the teeth 9 of the wire to a thickness of 2 to 20 μm by spray or brush, and heated at a low temperature of 100 to 150°C. By curing and forming the oxide ceramic R(3), the metallic wire for a spinning machine of the present invention is constructed.

In addition, the above 12 layers of ceramic can be applied to the upper surfaces of the teeth and edges by winding the wire around the required roll, or by winding it in a groove, and then spraying or coating the above paint, but masking is required before treatment. By doing so, it is also possible to treat only the teeth.

The take-in wire of the present invention has the above configuration,
The hardness on both sides is Hv19pO~2600, which is extremely high hardness compared to conventional Tekane wire wire made by hardening hard steel wire.

In addition to AljO, Zr is used as the oxide ceramic layer.

Compared to super hard alloy coated wire, the lifespan is 2.6 times longer.9.

Example 2 Combing wire for an air spinning machine according to another example of the present invention,

Effects of the Invention The metallic wire for spinning machines of the present invention is made of aluminum, copper,
Non-ferrous metal scraps such as zinc and its alloys - Because a ceramic layer of oxides, carbides, nitrides, etc. is formed on the surface of at least the teeth of the metallic wire for spinning machines, it has high toughness and This significantly improves wear resistance. In addition, because the surface is smooth, there is no localized wear caused by conventional thermal spraying of ultra-hard metals.
Furthermore, the invention has excellent corrosion resistance and significantly extends the service life.
