Description

Technical Field

[0001] The utility model relates to a bearing ring production line, in particular to an automatic lifting and feeding device for automatically conveying the bearing ring molding. Background Art

[0002] The specific production process of bearings: raw materials, inner and outer ring processing, steel ball or roller processing, cage (stamping or solid) processing, bearing assembly, bearing finished product. The traditional ring processing process varies depending on the raw material or blank form. 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, fine lapping or polishing, final inspection of parts, rust prevention, and storage. The blank of the bearing ring stamped out of the sheet is stamped twice after being stamped. Figure 7 The shape shown by the middle number a. One end face maintains the style of the plate and does not form a through hole like the conventional shaft side outer ring. Therefore, further stamping and punching processing is required. In order to reduce the use of manpower and enhance the degree of automation, the bearing ring blank a produced from the previous process will be input into a hopper through a conveying pipeline. There are various angles, and even two bearing ring blanks a can be nested together. In order to automatically adjust the bearing ring blank a to a suitable angle and feed it into the stamping mechanism, it is necessary to design an automatic bearing ring feeding device that screens and adjusts the angle from the hopper to the stamping device.
