Jiaxing bearing factory introduce you to the ring forming methods of rolling bearing manufacturing

Jiaxing bearing factory as a nationally known large state-owned enterprises, the main project: angular contact ball bearings, cylindrical roller bearing, spherical roller bearings, bearing speed railway passenger and so on. Jiaxing bearing factory sincere service users, to introduce the rolling bearing in the ring today what are the main forming methods, in the process of machining. Forging forming, cutting forming, cold rolling forming and cold ( Temperature) Extrusion. At present in the ring processing. A cold, cold rolling forming ring rolling process is a kind of can improve material utilization, improve the metal tissue compactness, keep the advanced technology of metal flow linear method, it is a kind of chipless machining method. Theoretically, the cold roll forming products without turning can be directly on heat treatment and grinding. At present, the cold rolling technology is mainly used in medium and small deep groove ball bearing, the main technological process is: forging blank, The ring) - - - - - - Turning ( In addition to the channel) - Rolling ( Ditch and chamfering) The whole path - Soft grinding both ends, is made of cold rolling technology and forging forming process, the precision of the products, in addition to the affected by the precision equipment also is affected by forming mold accuracy. Second, forging forming by forging processing, metal internal defects may be eliminated to improve metal organization, make the metal flow distribution is reasonable, good metal tightness. Forging forming process is widely used in bearing processing, can be done from ~ 20 mm inner diameter small products to outside diameter of 5000 mm oversize product processing. Common forging forming method are: hot forging, cold forging, machining, warm forging processing, mainly on hot forging in our country. Hot forging processing because of its different forming equipment is divided into: free forging process, the press forging process and forging machine forging process and high-speed upset forging process. Three, turning forming in the bearing industry, the traditional cutting molding technology is to use a special lathe, the concentration process method to complete the processing. But as a result of this method used equipment adjustment is difficult, low accuracy of machine tool, the material utilization rate is low, so the process is to be eliminated. With the development of science and technology, the numerical control turning machine tool developed rapidly and is becoming more and more perfect. At present, some of the complex shape, high precision products are increasingly using the numerical control turning molding technology. In the above molding method, forging forming most widely used, accounting for about 80% of the total output, for some small general products can be used in a bar Tube) Direct cutting molding. Since the 1980 s, some small and medium-sized enterprises in China is adopted in the production of small and medium sized ring, the cold rolling and cold ( Temperature) Extrusion molding process.
