Description

  The present invention relates to a spinning traveler used in a spinning machine and a twisting machine.

Conventionally, as a traveler used in a high speed region, in order to reduce the wear of the traveler and extend the life, the phosphate surface of the traveler is subjected to phosphoric acid treatment so that the phosphoric acid layer of calcium zinc phosphate has a thickness of 0.05 μm to 10 μm. In order to improve the initial familiarity with the ring and the ring, and to improve the yarn quality and productivity, a zinc calcium phosphate film is formed on the traveler's surface, and an epoxy resin film layer is provided Have been devised.

In the traveler configured as described above, it is a phosphoric acid layer of calcium zinc phosphate that mainly works with the ring during the operation of the spinning machine and the twisting machine, and has a certain sliding property and low wear property, For example, in spinning with a small amount of fiber lubrication between a ring and a traveler called compact spinning or cotton wax, there is little lubrication between the ring and the traveler, so the slipping characteristics and low wear characteristics cannot be said to be sufficient. In high-speed operation of the twisting machine, there is a problem that the wear of the traveler is remarkable, the life of the traveler is shortened, and the productivity is lowered.

  The traveler for a spinning machine of the present invention is made to solve the above-mentioned problems, and forms a metal traveler by forming a metal wire made of hard steel wire into a predetermined shape, and thereafter heat treatment such as quenching and tempering. After performing surface treatment such as surface polishing, degreasing and cleaning to clean the surface, and then performing phosphorylation treatment, a copper and iron phosphate compound having a needle-like structure on the surface of the metal traveler And a lubricating oil is provided in the fine holes of the needle-like structure, preferably the phosphoric acid compound layer has a thickness of 0.1 μm to 1.0 μm and a surface roughness of Rz 0.5 μm to 2.0 μm. Thus, the present invention provides a traveler for a spinning machine that has improved wear resistance of the traveler and has a significantly improved lifespan.

  As described above, a copper and iron phosphate compound layer having a needle-like structure is provided on the surface of the traveler, and lubricating oil is held in the fine holes of the needle-like structure. Lubricating oil retained in the fine holes in the needle-like structure during operation oozes out on the traveler surface, and even in special spinning such as fiber spinning between the ring and traveler or compact spinning with less cotton wax, a stable lubrication effect is achieved. It can be obtained over a long period of time, improving the wear resistance of the traveler and greatly extending the life of the traveler.

  In addition, since a phosphate compound layer of copper and iron is provided, a stable spinning state can be obtained at the beginning of spinning, yarn breakage and yarn unevenness can be reduced, and spinning with good yarn quality can be achieved. It has excellent effects, such as improved properties.

  Hereinafter, an embodiment of a traveler for a spinning machine according to the present invention will be described.

  1 to 3 show one embodiment of a traveler for a spinning machine according to the present invention, FIG. 1 is a front view, FIG. 2 is a sectional view taken along line XX of FIG. 1, and FIG. 3 is a schematic view of a phosphoric acid compound layer.

  As shown in FIG. 1 and FIG. 2, the traveler for a spinning machine of the present invention forms a metal traveler 1 having a predetermined shape by forming a metal wire made of hard steel wire.

  Further, the metal traveler 1 is subjected to heat treatment such as quenching and tempering to give a predetermined hardness (Hv650 to Hv750), and then surface polishing is performed, preferably the surface roughness is set to Rz 0.5 μm to 2.0 μm, Phosphoric acid treatment is performed to provide a copper and iron phosphate compound layer 2 having a needle-like structure on the surface of the metal traveler 1.

  Next, the metal traveler 1 is immersed in a lubricating oil tank, or the lubricant is sprayed onto the surface of the metal traveler 1 to lubricate the fine holes 4 in the phosphoric acid compound layer 2 having a needle-like structure. The spinning traveler 3 is configured such that oil is held or a lubricating oil film is formed on the surface of the hole 4.

  In the above configuration, after heat treatment such as quenching and tempering, the surface is preferably cleaned by degreasing and washing, and by doing so, abrasives such as media and compounds used for surface polishing The performance and lifespan of the metal traveler can be maintained and improved, and after the phosphorylation treatment, impurities attached to the surface of the metal traveler are removed by washing and drying as necessary. The lubricating oil is held in the fine holes 4 of the phosphoric acid compound layer 2 having the shape structure, or the lubricating oil film is formed on the surface of the holes 4 and then naturally or forcibly dried as necessary to ensure adhesion of the oil. can do.

  As shown in FIG. 1, the traveler for a spinning machine of the present invention is formed into a metal traveler 1 having a C-shape by forming a metal wire made of hard steel wire, and subjected to heat treatment of quenching and tempering, After imparting a hardness of Hv650 to Hv750, the surface is degreased with an alkaline solution as necessary and washed to clean the surface.

  The metal traveler 1 having a cleaned surface is polished by barrel polishing or the like to make the surface roughness Rz 0.5 μm to 2.0 μm, and then subjected to phosphorylation treatment to form a needle-like structure on the surface of the metal traveler 1. The copper and iron phosphate compound layer 2 is formed.

  A metal traveler 1 having a copper and iron phosphate compound layer 2 having a needle-like structure is immersed in an oil bath containing a lubricant for a certain period of time, and the fine holes 4 having a needle-like structure are impregnated with the lubricant. The held spinning traveler 3 is configured.

  The phosphoric acid compound layer 2 is formed, washed with water, and dried to remove impurities adhering to the surface of the metal traveler 1. Further, after forming a lubricating oil film on the surface of the hole 4, Forced drying can ensure oil adhesion and facilitate the handling of the traveler.
