The invention provides a method for
forging a bearing ring, and relates to the field of manufacturing of mechanical
metal, in particular to a technology for bearing
forging production. The method comprises the steps of material preparation: blanking 600g of each section of a round steel long bar;
forging forming: heating the material section by a
heating furnace, hammering the material section by high-speed hammering equipment, automatically conveying a hammered blank while cooling, performing spraying cooling to remove a
thin oxide layer generated on a semi-finished ball track under high temperature in time, then performing
cutting and final annealing, and performing forging on press
machine equipment; treatment after forging: removing waste products and repairing reprocessed products by detection; jacking: performing combined
cutting in a
punching hole to obtain a coarse bearing ring blank. In the forging process, precise
temperature control is adopted, so that the manufactured ring is extremely high in intensity, and a finally manufactured bearing is anti-abrasion and long in service; meanwhile, the
oxide layer can be removed in time in the forging process, and
cutting can be precisely carried out.
