The ferrule is an important part of the slewing ring. Due to the large variety of slewing rings, the size, structure, manufacturing equipment, and manufacturing methods of the slewing ring are different for different types of slewing rings. Cold Rolling Expands the shape and size of the required parts by using the plastic deformation of the material. Compared to traditional processing, there is no material removal, no strong vibration and noise. The advantages compared to turning are as follows:
1, Improve the utilization of materials
Compared with the traditional turning process, can save 15-30% of raw materials; material utilization from the current 44% to 55% -75%;
2, Reducing the processing operations
3, Improve the processing quality of the slewing ring
As a result of the implementation of cold rolling expansion will be to improve the overall quality of the bearing steel so that the slewing bearing rated life and calculated life expectancy reached 7-22 times the reliability of 99.93%
4, High production efficiency, the working environment has been optimized.
With the development of science and technology, CNC turning machine tools developed rapidly and improved gradually. At present, some of the more complex shapes and high precision products are increasingly using CNC turning forming technology. Ferrule forming the direction of processing should be toward the high utilization of metal materials, high efficiency, high precision molding direction. Therefore, cold rolling technology will be more and more applications.
