JPS616325A - Traveller for spinning machine - Google Patents

Abstract

PURPOSE:To improve wear resistance, to make a traveller run stably for a long period, to prevent frequent occurrence of end breakage, to suppress occurrence of fluff, and to prolong life of a traveller, by forming a carbide layer on the surface of the traveller by CVD method, or PVD method. CONSTITUTION:The carbide layer 2 such as TiC, ZrC, NbC, TaC, WC, B4C, SiC, etc. is formed by CVD method or PVD method on the surface of parts, which are at least brought into contact with a ring, of the traveller 1 for spinning machine consisting of hard steel wire or alloy steel wire.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a traveler for a spinning machine having good wear resistance.

BACKGROUND OF THE INVENTION Conventional travelers for spinning machines generally use hard steel wire or alloy steel wire, and some are subjected to surface hardening and quenching treatment, and then nickel plating.

However, under the harsh operating conditions in today's textile mills,
Conventional spinning trape 2 lacks abrasion resistance and wears out prematurely, causing unstable traveling of the traveler and frequent thread breakage, frequent occurrence of fuzz, premature seizing of the traveler and scattering, and further damage to the ring. The disadvantage was that the lifespan was shortened.

Therefore, in order to improve the wear resistance of the traveler, it has been considered to plate the traveler with chrome, but although chrome plating has high hardness, it has poor compatibility with the steel and Disadvantages include the fact that the spinning force is very high, the yarn breaks frequently, or the plating surface is prone to cracking, which causes peeling wear and abnormal wear of the traveler. There was a thunderstorm.

Means for Solving the Problems The present invention solves the above-mentioned drawbacks of the conventional spinning machine traveler. Yes, at least the surface of the traveler in contact with the ring has Tio, Zro,
Nbo, TaC, Wo.

The object of the present invention is to provide a traveler for a spinning machine that forms a carbide layer such as B4O181o and contributes to improved wear resistance.

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

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

The above traveler is 1 to 5 X 1 (0s at r'Torr)
A titanium carbide layer 2 with a thickness of 1 to 20 μm is formed on the surface in contact with the Schilling 7 lunge by glow discharge in a reactive gas atmosphere containing Hs t” as the main component and ion blating treatment, and then The traveler for a spinning machine of the present invention is constructed by quenching and then surface polishing.

The above-mentioned titanium carbide treatment layer can be applied to the entire optical surface of the traveler, but it only needs to be applied 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. I can do it.

The traveler for a spinning machine of the present invention has the configuration as described above.As shown in FIG.
It has extremely high hardness.

Figure 8 shows a comparison of the trapera firing rate when spinning was performed using the conventional nickel-plated traveler B and the spinning machine traveler At of the present invention under the following test conditions, and the firing rate of the traveler was 8 times higher. It can be seen that the amount decreases by more than 100%.

Test conditions Ring inner diameter: 45 cm 7 lunge width: 8.2 ws Fiber: polyester, cotton 46' days Spindle rotation speed: 5000 r, p, m Traveler:
Z8/hf 610 In the above embodiment, nine examples were shown by applying it to a horizontal traveler, but as shown in FIG. 4, titanium carbide ff121 is formed on at least the inner surface of the vertical traveler 8, and as shown in FIG. The traveler for a spinning machine of the present invention can be constructed by forming the titanium carbide layer 2 on the insert member 5 of the nylon traveler 4.

Since the vertical trapeller and metal insert nylon traveler also have a carbide layer on their surfaces, their wear resistance is significantly improved and their compatibility with the ring is also improved.

In addition, TiO, Zrc, Nbo, Tao, W (!
, B4O,Si.

In order to form a carbide layer such as, a P'VD method or an OVD method such as vacuum evaporation or snobbing may be used.

Effects of the Invention The spinning machine traveler of the present invention has a carbide layer tube formed on at least the surface of the spinning machine traveler made of hard steel wire or alloy steel wire that comes into contact with the ring, which has good adhesion to the base material. It has excellent abrasion resistance, allows the traveler to run stably over a long period of time, prevents frequent thread breakage, suppresses the occurrence of fuzz, and significantly extends the life of the traveler.
This invention has excellent effects.
