JPS6128029A - Traveller for spinning frame - Google Patents

Abstract

PURPOSE:To improve the abrasion resistance, fitness to the ring and the travelling stability of a traveller, and to suppress the generation of end breakage and fluffing, by forming an oxide layer to the surface of a traveller for a spinning frame by CVD process or PVD process. CONSTITUTION:An oxide layer 2 (e.g. Al2O3, ZrO2, SiO2, BeO, MgO, etc.) is applied to the spinning frame treveller 1 made of hard steel wire or alloy steel wire at least at the part contacting with a ring. For example, a silicon oxide layer 2 having a thickness of 1-20mu is formed on the surface contacting with a ring flange by the chemical vapor deposition process at 600-1,000 deg.C in a gaseous atmosphere composed mainly of SiCl4, CO2 and H2.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a travel 2 for a spinning machine that has good wear resistance and compatibility with a ring.

BACKGROUND OF THE INVENTION Conventional travellers 2 for spinning machines generally use hard steel wire or alloy steel wire, and some of them are subjected to quenching treatment as surface hardening treatment, and then nickel plating is applied thereto.

However, under the harsh operating conditions in today's textile mills,
Conventional spinning travellers lack abrasion resistance, causing early wear, leading to unstable running of the trape 2, frequent thread breakage, and frequent occurrence of fuzz, premature seizure and scattering of the traveler, 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 ring, and it There are disadvantages such as extremely high traveling force, frequent thread breakage, and easy cracking of the plating surface, which causes exfoliation and wear, causing abnormal wear on Trape 2. there were.

Means for Solving the Problems The present invention solves the above-mentioned drawbacks of the conventional traveler for spinning machines. A15o s + Z on the traveler surface in contact with the ring
The object of the present invention is to provide a traveler for a spinning machine that forms an oxide layer such as rOs 1 SiOs + Bθo 1MgO and contributes to improving wear resistance and compatibility with a ring.

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 above Traveler tl-9iO14,00s, Hs t-
A silicon oxide layer 2 with a thickness of 1 to 20 μm is formed on the surface in contact with the ring 7 lunge by chemical vapor deposition at 600 to 1000°C in a sulfur gas atmosphere with the main component, and then the surface is hardened. By polishing, the traveler for a spinning machine of the present invention is constructed.

Although the silicon oxide layer can be applied to the entire surface of the traveler, it is only necessary to provide it to at least the surface of the traveler that comes into contact with the ring, and by applying a masking treatment before the treatment, the silicon oxide layer can be applied to desired parts.

The traveler for a spinning machine of the present invention has the above-mentioned structure, and as shown in FIG. 2, the traveler A for a spinning machine of the present invention has an optical surface hardness of Hv 1600 to 2800, which is much higher than the conventional traveler B for a spinning machine.

In addition, the treated layer and the base material are bonded together by diffusion, making it possible to obtain better adhesion than plating.

Figure 8 shows a comparison of the traveler 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 8 times higher. It can be seen that it decreases.

Test conditions Ring inner diameter: 45gn1 7 lunge width = 8.2 Cod fiber: Polyester/cotton 45'8 Spindle rotation speed: 15000r, p, m Traveler:

In the above-mentioned embodiments, an example is shown in which the application is applied to a horizontal traveler, but as shown in FIG. By forming a silicon oxide layer on 24 insert members 6, one spinner for a spinning machine of the present invention can be constructed.

Since the vertical traveler and the metal insert nylon trape 2 also have a silicon oxide layer on their surfaces, their wear resistance is significantly improved and their fit with the ring is also improved.

In addition, Al gos, ZrO Gallery, 8101. Be

A PvD method such as sputtering or a CVD method may be used.

Effects of the Invention The spinning machine traveler of the present invention has an oxide layer with good adhesion to the base material 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. Excellent abrasion resistance for a long time D) The labeler runs stably, has good compatibility with the ring, prevents frequent thread breakage, suppresses the occurrence of fuzz, and significantly extends the life of the traveler. I can do it. In addition, since the oxide layer has good heat resistance, it has excellent high temperature fatigue resistance even in high speed spinning, and can further extend the life of the traveler. Furthermore, since the oxide 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.
