Problems solved by technology

[0003] The existing traveler uses domestic high-quality carbon structural steel such as 90# and T9A as raw materials, and is made through the process of flattening-annealing-pulling-forming-quenching-tempering-polishing-electroplating, and the service life of the traveler is average. In 3-5 days, the wear resistance, friction reduction and corrosion resistance are low, which cannot meet the requirements of compact spinning and high-speed ring spinning

Embodiment 1

[0019] (1) Material selection, high-quality alloy steel wire containing W, V, Ni, Co elements is selected as the raw material, and the material selection of TP (topaz) traveler is very particular, such as the best domestic alloy steel wire of 80WV, imported steel wire, etc. W, V, Ni, Co elements with excellent grinding and lubricating properties are added to the raw materials to improve the machinability, heat treatment properties, and final special surface treatment properties of the material.

[0020] (2) Filming, including the process of pressing and pulling, the pressing is to flatten the steel wire with a circular cross-section into a sheet, and the pulling is to determine the cross-sectional area, width and thickness dimensional tolerances, and regulations of the sheet through the die. Quality deviation and other indicators within the length to correct the error after pressing and improve the accuracy of the sheet. Rollers made of high-speed steel materials and ordinary ...

Embodiment 2

[0028] Other steps are the same as in Example 1, the difference is that the surface treatment of the step (7) is

[0029] The polished traveler was degreasing (60-80℃, 30min), washed with hot water for 1-5min, washed with water for 1-5min, activated with 10%-20% hydrochloric acid for 1-3min to remove surface rust and impurities, and then used to remove the surface rust and impurities. Washed with ion water, and finally placed in a composite plating tank with a plating solution containing 20-30g / L of nickel chloride, 0.5-2.0g / L of sodium borohydride, 40-90mL / L of ethylenediamine, and 5g of nano-SiC / L, nano-WC5g / L, nano-PTFE 5g / L and stabilizer, PH is controlled at 10-14, temperature is 80-90℃, stirring reaction is 0.5-5h, the thickness of the surface film layer should be ensured to be 2-30um, forming a dense , Uniform and firm film layer, with good wear resistance, anti-friction and anti-corrosion.

Embodiment 3

[0031] Other steps are the same as in Example 1, the difference is that the surface treatment of the step (7) is

[0032] The polished traveler was degreasing (60-80℃, 30min), washed with hot water for 1-5min, washed with water for 1-5min, activated with 10%-20% hydrochloric acid for 1-3min to remove surface rust and impurities, and then used to remove the surface rust and impurities. Ionized water washing, and finally placed in a composite plating tank with a plating solution containing 20-30g / L of nickel chloride, 0.5-1.0g / L of sodium borohydride, 40-60mL / L of ethylenediamine, nanometer MoS 2 5g / L, nano Al 2 O 3 5g / L and stabilizer, PH is controlled at 10-14, temperature is 80-90°C, stirring reaction is 0.5-5h, the thickness of the surface film deposition should be ensured to be 2-30um to form a dense, uniform and firm film layer, with Good wear resistance, friction reduction and corrosion resistance.

Abstract

The invention discloses a machining process of a TP (topaz) bead ring for spinning. The machining process is characterized by comprising the steps of: 1, selecting materials: selecting an excellent-quality alloy steel wire containing elements of W, V, Ni and Co as a raw material; 2, flaking; 3, annealing; 4, forming; 5, quenching-tempering; 6, polishing; and 7, carrying out surface treatment: nickelling the surface of a bead ring matrix by adopting a chemical plating method, and adding a nano powder body in a plating solution to ensure that the nano powder body is co-deposited on the bead ring matrix; and 8, carrying out surface curing treatment: removing the stress and enhancing the hardness to ensure the surface of the bead ring is golden yellow. The TP bead ring machined by adopting the machining process has relatively good abrasion resistance, friction reduction and corrosion prevention properties, is capable of well meeting the requirement on the existing high-count, high-speed and high-efficiency spinning, is particularly suitable for compact spinning and common high-speed ring spinning, and has a good development prospect and a wide market popularization space.

Description

technical field [0001] The invention relates to the technical field of spinning, in particular to a processing technology of a TP (topaz) traveler. Background technique [0002] my country is a big textile country, and the textile industry has become an important civilian production industry in our country. With the development of the industry, spinning has developed in the direction of high speed, high count, high density, automation and compact spinning. In addition to traditional cotton spinning, special fibers, new fibers, carbon fibers, cotton-like fibers, etc. have appeared. Various performance indicators, especially wear resistance, friction reduction, and corrosion resistance, put forward higher requirements. [0003] The existing traveler is made of 90#, T9A and other domestic high-quality carbon structural steel as raw materials, and is made through the process of flattening-annealing-pulling-forming-quenching-tempering-polishing-electroplating. In 3-5 days, the ...
