At present in the process of forming method, collar basically has the following kinds: forging molding, turning molding, cold of mid-plane molding and cold extrusion temperature). In the above processing methods, forging forming most widely used, about 80% of the total production, for some small gm products can use stick (tube) material directly shape. Turning Since the 1980 s, our country some small and medium enterprise in the small contractor is adopted in the production of cold rolling expansion and cold extrusion technology (temperature).
1) forging forming
Through the forging process can eliminate metal internal defects, improve the metal organizations, reasonable distribution of metal flow pattern, metal close for good. Forging forming processing technology is widely used in processing, KOYO bearing can be finished inside ~ 20 mm from small products to 5000 mm diameter of large product processing. Common forging the shaping method: hot forging processing, cold forging processing, forging, our country to processing temperature hot forging primarily.
Hot forging process because of its forming equipment different and divided into: free forging process technology, press forging process, multistep forging machine forging process and high-speed upset forging machine forging process.
2) cold rolling forming
Cold rolling is a kind of can improve material utilization and improve organization density, keep metal metal flow of the advanced technique, linear it is a kind of a chipless machining method. In theory, cold rolling forming products to turning can be directly by heat treatment and grinding. At present, the cold rolling mainly used in medium and small deep groove ball bearings, the main technological process for:
Forging blank (ring)-turning (except channel)-of mid-plane (ditch and corner) the whole size-miropowder end two.
By cold rolling and forging molding process, the precision of the products by equipment precision outside influence in addition, but also the influence of accuracy by forming die.
3) turning molding:
In KOYO import bearing industry, the traditional turning molding technology is using a special lathe, the focus on process method is used to complete processing. But because the method equipment used adjusting difficulty big, machine tool low accuracy, low material utilization ratio, so the process methods are being phased out.
In tianjin import bearings Co., LTD. Was established in 2000, is the numerous well-known bearing company authorized dealer, the main business SKF bearing and bearing, FAG SKF NSK bearings, bearing IKO bearing, KOYO bearing, TIMKEN bearing, NTN bearing, "INA" bearing import bearings, and owns a lot of stock.
