Japanese seiko developed new methods of wheel hub bearing components

Japanese seiko announced that developed the use of high strength material, to cold rolling forming a new way to make special passenger car wheel hub bearing components. Compared with hot forging cold forging can improve the strength, but need several times the forming pressure when processing. The company applied for smaller pressure makes large flange forming 'profile extrusion method', implements the forming of low pressure. In ensuring the strength reliability, light-duty implementation aspects at the same time, the customer's demand is higher and higher. Cold rolling forming than previous hot forging, as a result of improved degree of strain hardening and surface finish, so can improve the strength. Strength increase, circular flange can be accordingly by changing the shape and so on ways to reduce 30% of the weight, so that the wheel hub component overall reduced more than 15%. However, cold rolling forming heat forging is more difficult to machining. Pressure for forming this difficult problem, through the compression flange part of the finale, reducing the surface area of the forming parts. Extrusion of the axis of smaller, make the flange part forming with larger area. The area of the pressure on the processing process from beginning to end. 【 Bearing.
