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.

Conventional technology and problems to be solved by the invention Conventional spinning machine travelers generally use hard steel wire or alloy steel wire, are subjected to quenching treatment as a surface hardening treatment, and then nickel plating is applied in some cases. .

However, under the harsh operating conditions in today's textile mills,
Conventional spinning travellers lack abrasion resistance, causing early wear, leading to unstable travel of the traveller, resulting in frequent yarn breakage, 9 fuzzing, premature seizure and scattering of the trapeller, and further shortening the lifespan of the ring. The disadvantage was that it was shorter.

For this reason, in order to improve the wear resistance of Trabe 2, it has been considered to chrome plate the trapella, but although chrome plating has high hardness, it does not fit well with the ring.
In the early stage of spinning, the spinning force is very high, the yarn breaks frequently, or the plating surface is prone to cracking.
This caused problems such as peeling and wear, which caused abnormal wear of the trapezoid 2.

Means for Solving the Problems The present invention solves the above-mentioned drawbacks of the conventional traveler for spinning machines. The ion evaporation thin film forming equipment vaporizes metals such as boron, aluminum, titanium, silicon, chromium, and nickel and deposits them on the ring surface while simultaneously vaporizing them with nitrogen and carbon.

Boron nitride is irradiated with an ion beam of phosphorus, etc.

Bonded aluminum, boron carbide, titanium nitride.

We provide a traveler for spinning machines in which a uniform thin metal film of nickel, phosphorus, chromium carbide, etc. is formed at least on the surface of the traveler in contact with the ring, which improves compatibility with wear-resistant rings, prevents seizure, and prevents the traveler from scattering. It is something to do.

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 having a desired shape as shown in FIG.

The ion implantation section and the vacuum evaporation section are loaded into a vacuum container of an ion evaporation thin film forming apparatus, and titanium is evaporated by electron impact evaporation and deposited on the surface of the traveler, and at the same time nitrogen ions are irradiated from the ion implantation apparatus. The traveler for a spinning machine of the present invention is constructed by implanting a titanium nitride layer gt into the deposited film, forming a titanium nitride layer gt with a thickness of 2 to 20 μm on the surface in contact with the ring 7 flange, and then hardening and polishing the surface.

Note that the treated 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 on at least the surface of the traveler 2 that comes into contact with the ring. It can be applied to

Further, as shown in FIG. 2, the treated layer is formed on the traveler base material 8
A mixed layer 5 is formed in which the metal elements of the treated layer 4 and the treated layer 4 are mixed together by diffusion near the interface, and the metal elements are strongly bonded to each other, resulting in extremely excellent adhesion.

The traveler for a spinning machine according to the present invention has the above-mentioned configuration, and as shown in FIG. The friction coefficient is low and smooth, and it fits well with the ring. Further, the treated layer and the base material are bonded together by diffusion, and adhesion can be obtained that is superior to that obtained by bonding Φ or physical vapor deposition.

Figure 4 shows a comparison of the trapera firing rate when spinning under the following test conditions using the conventional nickel-plated traveler B and the spinning machine traveler A of the present invention, and the traveler firing rate is more than three times as high. It can be seen that it decreases.

Test conditions Ring inner diameter: 45IIIJI Width: 8.2ms Fiber: Polyester, cotton 45'8 Spindle rotation speed: 15000r, p, m) 5 to 5
: ZS/hf 610 In the above embodiment, an example was shown in which the application was applied to a horizontal traveler, but as shown in FIG.
6, a boron nitride layer 10 is applied to the insert member 9 of the metal insert nylon traveler 8.
It is heat resistant due to its formation.

It is possible to construct a traveler for a spinning machine according to the present invention, which has good lubricity, wear resistance, and long life characteristics.

Effects of the Invention The spinning machine traveler of the present invention is made of hard steel wire or alloy steel wire, and has a titanium nitride layer with good adhesion to the base material, a boron nitride layer, and a boron nitride layer on at least the surface that contacts the ring. silicon carbide layer.

Because it has a treated layer such as 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, compatibility with the ring, and preventing thread breakage. It is possible to prevent frequent occurrence of fuzz, suppress the occurrence of fuzz, and significantly extend the life of the traveler. Furthermore, 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.
