Embodiment
[0019] Concrete preparation steps include:
[0020] a) Prepare the thin plate, the thin plate is made of medium carbon steel material, which is made by casting, forging, calendering, cutting and other processes. The specification of the prepared thin plate is 36*22*0.8mm. 35Mn;
[0021] b) Surface heat treatment, the surface heat treatment process used in the present invention is flame heating surface quenching, the quenching method is linear moving heating, mainly heating and quenching the contact parts where the traveler and the steel ring produce relative motion, and the contact parts are mainly distributed on the thin plate The length of the inner foot part is 8mm, and the length of the outer foot part is 6mm. After quenching, the thin plate can be completely hardened; the fuel used in the surface quenching process is acetylene or methane, and the heating temperature is controlled at 2000-2600℃, the quenching method is water quenching or right quenching, and polyvinyl alc...

Abstract
The invention discloses a preparation method of a novel wear-resistant steel wire ring. The preparation method mainly comprises the following steps of: a) preparation of a thin plate; b) surface heat treatment; c) cutting of the thin plate; d) bending and forming; and e) stress relief annealing. In the preparation method disclosed by the invention, the arrangement of the working procedures is reasonable, the cost is suitable, the local surface of the steel wire ring after surface heat treatment shows excellent wear resistance, and the part without heat treatment can still maintain good plasticity and toughness, so that the steel wire ring can be better bent and formed; and in a treatment method, the implementation of the preparation process of the steel wire ring is simpler and more convenient, and the practicability is higher.
Description
technical field [0001] The invention relates to a method for preparing a traveler, in particular to a method for preparing a traveler with excellent wear resistance and moderate preparation cost, and belongs to the technical field of textile equipment. Background technique [0002] The traveler is one of the key equipment of the ring spinning frame and twisting machine, it directly affects the twist of the yarn, package density, broken end, hairiness and the number of cotton balls, the use of high-quality traveler can improve the quality of the yarn Improve the quality grade, increase the output of the yarn, reduce the return, reduce the cost, and increase the output value and benefit. [0003] The contact surface between the traveler and the ring and the contact surface between the traveler and the yarn are subject to high wear. In order to increase the output, the traveler must be raised to a higher operating speed, which affects the durability of the traveler. Abrasivene...
