发布时间:2018-10-11 15:07
【摘要】:轴承作为机械设备中必不可少也是举足轻重的零部件,在国民经济和国防建设中具有重要的作用,目前我国轴承行业已经得到了飞速的发展,但在一些高端市场和特殊领域还要依赖进口,轴承的质量还需要不断的提高。轴承的寿命和可靠性还不能完全满足主机发展的要求。瓦轴集团作为中国轴承行业的领军人物,虽然在产能上占据了一定优势,但在轴承质量方面还需要进一步提高,尤其是目前用户对轧机轴承的抱怨不断升高,轧机轴承频繁出现质量问题,滚道剥落、轴承碎裂、保持架等问题影响了轴承的使用寿命,因此,我们有必要对影响轴承质量的原因进行深入研究,以提高轴承的使用寿命,赢得用户的认可。 本文通过对瓦轴集团主导产品轧机轴承生产过程的质量控制研究,来提高轧机轴承的质量,解决轧机轴承寿命及可靠性低的问题,以适应市场的要求,提高企业的竞争力,并争取早日实现国产轴承替代进口。 首先,本文对瓦轴集团的轧机轴承产品发展趋势做了简单的分析,并通过与国外轧机轴承的对比,明确存在的差距,,并分析了瓦轴集团质量管理现状。其次,统计了轧机轴承在用户中出现较频繁的质量问题,通过对影响轧机轴承产品质量的原因进行分析,明确了设备的加工能力、轴承的设计方法是影响轴承质量问题的主要原因。并通过对设备的改造和轧机轴承产品的优化设计,来提高轧机轴承的质量,实行了生产过程的质量控制。同时,通过对质量控制的持续改进情况进行探讨,把轧机轴承的质量控制作为一项长期的质量行为来控制,以期得到稳定的产品质量。 本文以质量管理理论为基础,主要通过对钢厂进行走访获得轧机轴承在用户中使用的情况,并采用统计方法对影响轧机轴承寿命的原因进行分析,运用质量管理的相关知识对生产过程的质量进行控制。通过本文的研究,解决了瓦轴集团轧机轴承使用寿命低的问题,满足了用户的要求。
[Abstract]:Bearing, as an indispensable and important part in mechanical equipment, plays an important role in the national economy and national defense construction. At present, the bearing industry in China has been developing rapidly. But in some high-end markets and special areas have to rely on imports, bearing quality also needs to continue to improve. The life and reliability of the bearing can not fully meet the requirements of the development of the main engine. As the leading figure in China's bearing industry, although it occupies a certain advantage in production capacity, it still needs to further improve its bearing quality, especially in the light of the rising complaints from customers about rolling mill bearings at present. There are frequent quality problems in rolling mill bearings, such as raceway spalling, bearing fragmentation, cage and so on, which affect the service life of bearings. Therefore, it is necessary for us to deeply study the causes affecting bearing quality in order to improve the service life of bearings. Win the user's approval. In this paper, the quality control of rolling mill bearings, which is the main product of the rolling mill, is studied in order to improve the quality of rolling mill bearings and solve the problems of low service life and reliability of rolling mill bearings, so as to meet the requirements of the market and improve the competitiveness of enterprises. And strive for the early realization of domestic bearings to replace imports. Firstly, this paper makes a simple analysis on the development trend of rolling mill bearing products of the bearing group, and through the comparison with the foreign rolling mill bearings, it makes clear the existing gap, and analyzes the present situation of the quality management of the rolling mill bearing group. Secondly, the frequent quality problems of rolling mill bearings are analyzed, and the processing ability of the equipment is clarified by analyzing the reasons that affect the product quality of rolling mill bearings. Bearing design method is the main cause of bearing quality problem. By improving the equipment and optimizing the design of rolling mill bearing product, the quality of rolling mill bearing is improved, and the quality control of production process is carried out. At the same time, through the discussion of the continuous improvement of quality control, the quality control of rolling mill bearings is regarded as a long-term quality behavior in order to obtain stable product quality. Based on the theory of quality management, this paper obtains the use of rolling mill bearings in customers by visiting the steel mills, and analyzes the reasons that affect the life of rolling mill bearings by statistical method. Use knowledge of quality management to control the quality of production process. Through the research of this paper, the problem of low service life of rolling mill bearing of bearing shaft group is solved, and the requirement of customer is satisfied.
