Mechanized process contemporary society, stainless steel fastener, although is small components, but in the mechanical device is an essential part, also played the very vital role. Therefore we when use the fastener, needs to carry on the regular safeguarding maintenance, like this can guarantee a fastener more secure use, and can lengthen fastener's service life, enhances mechanical device's operational performance. When we when carries on safeguarding to the fastener, which problems does the regular session have? It mainly has three major problems: 1st, in has carried on to the fastener quenching processes, must use the silicate cleansing agent to clean up the above impurity, then wants carefully to carry on the rinse, under avoids remaining the impurity above the fastener, affects to its normal application. 2nd, fastener after drawing temper, its color will change possibly, will soak the fastener after the ether period of time, will have the greasy material production, will have such situation to indicate that the fastener will be not very clean. After carrying on has analyzed, will detect to fastener heating time piles up is not very reasonable, the fastener will have some tiny oxidized phenomenon possibly in the middle of the quenching oil. 3rd, above fastener, if has white material time, very possible is some phosphides. Presents this kind of phenomenon the reason is because has not used the acidic clearer to carry on cleanly, moreover yo examination potcher time is not very careful. If these questions cannot prompt processing, to the immediate influence to the fastener performance use, also will cause fastener's service life to lessen possibly, creates the fastener to get up early the damage phenomenon and so on. Above hoped that three major problem matters needing attention can help everybody better use fastene
Because gasket's broad use in the thread fastener the bolt, the bolt, nut's area of bearing is mainly impossible to do very much big (material and craft limit), to reduce the bearing surface the compressed stress, safeguards is used by bridge piece's surface the gasket. Its following Chinese standard letter network share usually gasket material selection and processing craft knowledge. Plain washer choice of material: The gasket should use the hot rolling steel plate, hot rolling and the acid pickling steel plate or the cold rolling steel plate ramming processing' or uses good processing method manufactures and so on material, tubing material cutting as well as rolling, forging. The specific processing method selects the determination by the manufacturer. Plain washer processing craft: The plain washer processing craft mainly has two kinds, one kind is now fin cutting processing, another kind is surface protection processing; Fin cutting processing, the gasket should use polishing, the vibration or other method fin cutting and the edge. Surface protection processing, in standard to gasket product surface treatment according to coating (thick) and coating (thin) the discrimination, the author thought that should be suitable similarly for a other fastener product bolt (the bolt, the stud> and the nut. Although has not looked like this standard narration like this specificly in other corresponding standards.
In recent years, the Chinese fastener profession held the steady growth situation, accelerates the fusion with various countries economy, causes it to become in gradually the international economy a noticeable strength. Countries and so on US, Japan, Germany, France, Britain, Canada, Italy, South Korea and Spain year by year are also rising to the Chinese fastener's demand. Chinese automobile fastener product variety satisfies rate has achieved above 60%, the domestic market satisfies rate has reached as high as above 70%. Although the Chinese fastener profession undergoes more than ten years considerable developments, but in the profession the small and medium-sized enterprise stands in great numbers the aspect not yet changes, low, small, disperses is one of Chinese fastener profession key characters, the profession development must take advantage in the production technology continues the innovation and the development. The Chinese Fastener Enterprise thousands, at present in the sales scale and the property scale, the Small and medium-sized enterprise is the main army who the fastener profession does not pass on responsibilities. The industrial research institute "2015-2020 Year Chinese Fastener Profession Production and marketing Demand forecast And Reforming Upgrade Analysis report" the statistical data displayed that in 2014 the Chinese ten big fastener Production enterprise ranking is as follows: in 2014 the Chinese ten big fastener Production enterprise places 1: Sichuan Ipin Iraq strength group Limited company 2: Jin hundred million industry Limited liability company 3: Changshu Standard letter Factory 4: Zhejiang Dongming stainless steel product Limited liability company 5: Ningbo gold tripod with two handles fastener Limited company 6: Sintai city with joint forces fastener Limited company 7: Shandong excel in fastener Limited company 8: Shanghai sign five
