Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a traveler for a spinning machine that has wear resistance, heat resistance, corrosion resistance, and good compatibility with a ring.

BACKGROUND ART AND PROBLEMS TO BE SOLVED BY THE INVENTION Conventional spinning machine travelers generally use hard steel wire or alloy steel wire, undergo quenching treatment as surface hardening treatment, and then nickel plating in some cases.

However, under the harsh operating conditions in today's spinning mills, conventional travelers for spinning machines lack abrasion resistance and wear out prematurely, leading to unstable travel, frequent yarn breakage, and fuzz. This problem occurred frequently, causing the traveler to seize prematurely and scattering, and furthermore, the life of the ring was shortened.

For this reason, in order to improve the wear resistance of the traveler, it has been considered that the traveler is coated with chrome plating, but although chrome plating has high hardness, it has poor compatibility with the ring, and the spinning force increases in the early stage of spinning. There were disadvantages such as the threads becoming very expensive, causing frequent thread breakage, or cracks easily forming on the plating surface, which caused peeling wear and abnormal wear of the traveler.

Means for Solving the Problems The present invention solves the above-mentioned drawbacks of the conventional spinning machine traveler, and the invention provides a spinning machine traveler made of hard steel wire or alloy steel wire with an ion implantation part and a vacuum deposition part. Using an evaporation film forming apparatus, metals such as boron, aluminum, titanium, silicon, chrome, and nickel are vaporized and deposited on the ring surface, and at the same time an ion beam of nitrogen, carbon, phosphorus, etc. is irradiated to form boron nitride. , aluminum nitride, boron carbide, titanium nitride, nickel, phosphorus,
To provide a traveler for a spinning machine, in which a uniform metal film such as chromium carbide is formed on at least the surface of the traveler in contact with the ring, which improves compatibility with the wear-resistant ring, prevents seizing, and contributes to the scattering of the traveler. be.

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

Example 1 A hard steel wire rod is formed into a horizontal traveler 1 having a desired shape as shown in FIG.

The ion evaporation film is loaded into the vacuum container of the ion evaporation film forming device, which consists of an ion implantation section and a vacuum evaporation section, and titanium is evaporated by electron impact evaporation to be deposited on the traveler surface. At the same time, nitrogen ions are irradiated from the ion implantation device to form a vapor. The traveler for a spinning machine of the present invention is constructed by driving into the film, forming a titanium nitride layer 2 with a thickness of 2 to 20 μm on the surface that contacts the ring flange, and then hardening and polishing the surface.

Note that the treatment layer of the titanium nitride layer 2 can be applied to the entire surface of the traveler, but it is only necessary to provide it to at least the surface of the traveler that comes into contact with the ring, and it can be applied to the required parts by masking before treatment. .

In addition, as shown in FIG. 2, the treated layer forms a mixed layer 5 in which the metal elements of the traveler base material 3 and the treated layer 4 are mixed by diffusion near the interface, and the metal elements are strongly bonded to each other and adhere closely. It has very good sex.

The traveler for a spinning machine of the present invention has the above-mentioned configuration, and as shown in FIG. is low and smooth, and blends well with the ring. Further, the treated layer and the base material are bonded by diffusion, and it is possible to obtain better adhesion than plating or physical vapor deposition.

Figure 4 shows a comparison of the traveler burn rate when spinning under the following test conditions using the conventional Nikkel Metsuki Traveler B and the spinning machine traveler A of the present invention, and the traveler burn rate is reduced by more than three times. I understand that.

Test conditions Ring inner diameter: 45mm Flange width: 3.2mm Fiber: Polyester. Cotton 45 ^'S Spindle rotation speed: 15000r.pm Traveler: ZSC/HF 6/0 In the above embodiment, an example of application to a horizontal traveler was shown, but as shown in Fig. 5, at least the inner surface of the vertical traveler 6 is nitrided. By forming the aluminum layer 7 or forming the boron nitride layer 10 on the insert member 9 of the metal insert nylon traveler 8 as shown in Fig. 6, it has good heat resistance and lubricity, and has excellent wear resistance and life expectancy. A traveler for a spinning machine according to the present invention can be configured.

Effects of the Invention The spinning machine traveler of the present invention is made of a hard steel wire or an alloy steel wire, and has a titanium nitride layer and a boron nitride layer, which have good adhesion to the base material, on at least the surface that contacts the ring, and a carbonized boron nitride layer. Because it has a treated layer such as a silicon layer or an aluminum nitride layer, it has excellent wear resistance, lubricity, heat resistance, and corrosion resistance, allowing the traveler to run stably over a long period of time, and compatibility with the ring. It is possible to prevent frequent thread breakage, suppress the occurrence of fuzz, and significantly extend the life of the traveler. In addition, since the titanium nitride layer contributes to improving corrosion resistance, this invention has excellent effects such as being able to prevent rusting of the traveler even when used for spinning flame-retardant fibers.
