Processing technology of bearing parts:

(1) Bearing parts manufacturing-bearing parts inspection-bearing Parts demagnetization, cleaning, rust prevention - bearing assembly - bearing finished product inspection - bearing finished product demagnetization, cleaning - bearing finished product oiling packaging bucket finished product storage.

(2) The ferrule is an important part of the rolling bearing. Due to the wide variety of rolling bearings, the size, structure, equipment and process methods of the ferrule of different types of bearings are vary. And because the ferrule has many processing procedures, complex technology and high processing accuracy requirements, the processing quality of the ferrule has an important impact on the accuracy, service life and performance of the bearing.

The raw material of the ring is cylindrical bar or tube. Rolling bearing rings generally have the following manufacturing processes.

(1) Bar material: blanking - forging - annealing (or normalizing) - turning (cold forming) - heat treatment quenching, tempering - grinding - parts inspection - Demagnetization, cleaning - Submit assembly.

(2) Bar material and tube material: blanking - cold rolling forming - heat treatment quenching, tempering - grinding - parts inspection - demagnetization, cleaning - submit assembly.

(3) Tube material: blanking-turning-forming-heat treatment-grinding-parts inspection-demagnetization, cleaning-submission for assembly

(4) Bar material: blanking - cold (warm) extrusion - turning - heat treatment quenching, tempering - grinding - parts inspection - demagnetization, cleaning - submit assembly

At present, the forming methods in the ferrule processing mainly include the following: forging forming, turning forming, cold forming Roll forming and cold (warm) extrusion.

(1) Forging molding Through forging 3 processing, the inherent defects of the metal can be eliminated, the metal structure can be improved, the metal streamline distribution is reasonable, and the metal tightness is good. Forging forming process is widely used in bearing forming processing, common forging forming methods are: hot forging, cold forging, warm forging.

(2) The stamping forming process is an advanced process method that can improve the utilization rate of materials, improve the compactness of the metal structure, and maintain the metal flow linearity. processing method. When the stamping process and the forging process are used, the accuracy of the product is not only affected by the accuracy of the equipment, but also by the accuracy of the forming die.

(3) The traditional turning and forming technology is to use a special lathe and use a centralized process method to complete the forming process. Some products with complex shapes and high precision requirements are increasingly using CNC turning forming technology.

Except when using hot forging process, bearing accessories usually select suitable metal processing according to different processes Oil to improve workpiece accuracy and machining efficiency.

(1) Cold forging: Cold heading forming oil or strong shrinking oil are often used to improve the accuracy of the workpiece.

(2) Stamping: Since the stamping process is limited by the accuracy of the mold, special stamping oil is used to prolong the service life of the mold, thereby ensuring the accuracy of the workpiece.

(3) Turning> The accuracy of the turning process is mainly related to the feed speed and tool strength of the cutting process. The use of special lathe cutting oil can effectively reduce the cutting temperature and prevent heat. The appearance of deformation.

The above is a brief introduction to the processing technology of bearing rings. Bearing processing is developing in the direction of high utilization of metal materials, high production efficiency and high forming accuracy.
