Development Of Ring Travellers

At present, most cotton spinning enterprises have already felt the depression of the development of the industry. How long will this recession last? Many leaders of steel collar and traveller equipment manufacturers have expressed concern about this problem. Hao Wei, deputy general manager of Tianjin Zhendong textile special equipment Co., Ltd. believes that the real recovery of the industry will take a relatively long time, and may experience a transitional period of 4~5. Yang Chongming, chairman of Chongqing Jinmao Textile Equipment Co., Ltd. Textile industry Has entered an important adjustment period, some production factors and market resources allocation has gradually concentrated on the trend of large enterprises, polarization has become increasingly obvious, the advantages of the dominant enterprises will be bigger and bigger. Under such circumstances, there are only three ways for small and medium-sized textile enterprises to face: first, speed up the pace of escalation and go against the trend; two, transformation (transformation); and three, shutting down and closing down. There are no alternatives except these three roads. Textile equipment enterprises are also facing the same fate. During the interview, the reporters learned that, for the small and medium-sized enterprises that most preferential policies could not take into account, there was no better way to get rid of the current difficulties than the enterprises themselves in strengthening their independent innovation and upgrading their products. At present, the primary task of equipment manufacturers is still how to survive.

In recent years, the main products of some high end steel rings and travellers in China are mainly produced. performance index Although it has reached or reached the level of famous brand products abroad, some key indicators even exceed foreign products. However, there is still a certain gap between individual products, individual products, service life and stability in comparison with similar products abroad. In order to enhance the competitiveness of the market, many enterprises have been trying to narrow the gap in technology as soon as possible. Such measures as accelerating the upgrading of raw materials (high quality products imported high quality steel), finishing processing and upgrading (using sophisticated advanced equipment) and surface treatment upgrading have achieved remarkable results. For example: the Chongqing Golden Cat Corporation's steel wire ring production uses high-precision triple and quadruple rolling mill, one-time production technology, instead of the original traditional flat die drawing process, greatly improving the sheet accuracy and smoothness, reducing the process flow, shortening the production cycle, reducing the employment and improving the production rate of products. At the same time, the past multi step process and multiple processes have become a one-step production process, which greatly reduces the quality problems of the production process. In terms of heat treatment, some enterprises adopt advanced bell type furnace to replace the original well type furnace, and adopt imported quenching and tempering equipment instead of the original vibrating furnace, thus greatly improving and improving the heat treatment performance of the traveller. Adopting many new surface treatment technologies, greatly improves the self lubrication and wear resistance of the ring traveller products, and better meets the needs of spinning high and high speed, all kinds of special fibers and replacing the import.

In the past, low carbon steel was used to carburizing domestic steel collar products. Production process Nowadays, many enterprises are replacing steel with high quality steel, such as alloy steel, bearing steel and so on. In addition, high precision CNC lathe, internal and external runway grinder, upper and lower surface grinding equipment are put into use. The traditional processing technology has been changed to produce a real high precision collar. The roundness of the inside and outside runway, the flatness of the upper and lower planes, and the error of uneven shape are controlled within 0.01 millimeters, and their accuracy reaches and surpasses the advanced level of similar products abroad. Due to the use of high quality materials, precision machining, advanced heat treatment technology and special surface treatment, the service life of the collar has increased from last year to 3~5. It is possible to achieve the goal of replacing imports with excellent comprehensive cost performance advantages.
