Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a spinning machine traveler used in spinning machines, yarn twisting machines, and the like.

Conventionally, metal travelers have been used for spinning machines, but with the recent high-speed rotation and high-speed spinning aimed at high productivity, the friction between the ring and the traveler is intense, causing rapid wear of the traveler and shortening its lifespan. This caused the thread to become short and the traveler to be scattered due to traveler burn, leading to thread breakage. Therefore, in order to improve the wear resistance of the traveler, it was considered that the traveler was coated with chrome plating, but although chrome plating has very high hardness, it did not fit well with the ring, and the spinning force was extremely high in the early stage of spinning. This has the disadvantage that the threads become more expensive and breakage occurs frequently due to thread plucking.Furthermore, the plating surface tends to crack, which causes exfoliation and wear, resulting in abnormal wear of the traveler.

The present invention provides a traveler for a spinning machine that eliminates the above-mentioned conventional drawbacks, and one embodiment of the present invention will be described below with reference to the drawings.

Embodiment FIG. 1 shows an embodiment of a traveler for a spinning machine according to the present invention.
Shown in Figure 2.

As shown in the figure, the entire surface including the inner surface 2 of a horizontal metal traveler 1 is made of Ni containing 25% by weight of Fe.
- A traveler for a spinning machine is constructed by forming the Fe alloy plating layer 3 to a thickness of 10μ.

In the above embodiments, the thickness of the coating layer is 1 μ to 20 μ, which is optimal for a traveler for a spinning machine. That is,
If the thickness is less than 1μ, it will wear out due to wear in the early stages of use, resulting in a shortened service life.If the thickness exceeds 20μ, peeling and wear may occur due to sliding contact between the ring and the traveler, or between the thread and the traveler, resulting in abnormal wear. It causes.

In addition, 5 to 40% iron can be eutectoid with nickel.

In the spinning machine traveler of the present invention, at least the inner surface of the metal traveler that comes into contact with the ring is plated with Ni-Fe alloy, so that the Ni-Fe alloy has a good relationship between the ring and the traveler, especially in the early stages of use of the traveler. Forms a lubricant layer, which improves the initial conformity of the traveler to the ring and greatly reduces thread breakage and traveler burn.

In addition, the wear resistance between the traveler and the ring is reduced, and the ductility is high, so there is less cracking or peeling of the plating, and as shown in Figure 3, the amount of wear is significantly reduced compared to the conventional Nickel plating Traveler A. This invention has excellent effects such as being able to greatly extend the life of the machine and being inexpensive.
