Description

Technical Field

[0001] The utility model relates to bearing ring manufacturing equipment, in particular to an automatic punching device for a bearing ring. Background Art

[0002] The specific production process of bearings includes: raw materials, inner and outer ring processing, steel ball or roller processing, cage processing (stamping or solid), bearing assembly, and finished bearings. The traditional ring processing process varies depending on the raw materials or blank forms. The entire inner and outer ring processing process is: bar or tube material (some bar materials need to be forged and annealed, normalized), turning, heat treatment, grinding, lapping or polishing, final inspection of parts, rust prevention, and storage. The outer ring blank of the bearing stamped out of sheet material is stamped twice after the stamping process. Figure 4 The image shown by number a in the middle. One end surface maintains the plate's form and lacks the through-holes typically found on shaft-side outer rings. Therefore, further stamping and blanking are required. Summary of the Invention
