Abstract

The invention provides a stamping device for forming a bearing retainer, and belongs to the technical field of machinery. The stamping device for forming the bearing retainer comprises a rack, a first push rod motor is fixed to the rack, a lifting column is fixed to a push rod of the first push rod motor, the lifting column is connected with the rack in a sliding mode, a first driving motor is fixed to the top end of the lifting column, a cylindrical rotating table is fixed to an output shaft of the first driving motor, a limiting frame is fixed to the lifting column, an annular limiting groove and a stamping groove are formed in the circumferential surface of the rotating table, a discharging hole connected with the stamping groove is formed in the rotating table, and an elastic supporting assembly used for fixing a bearing retainer blank is arranged in the limiting groove.

Description

technical field [0001] The invention belongs to the technical field of machinery, in particular to a stamping device for forming a bearing cage. Background technique [0002] The cage (that is, the bearing cage, also known as the bearing cage) refers to the bearing parts that partially wrap all or part of the rolling elements and move with them, to isolate the rolling elements, and usually guide the rolling elements and keep them in the bearing Inside. [0003] The cage is generally processed by die-casting or plastic casting. The die-casting method needs to melt the raw materials and pour them into the die-casting mold of the die-casting machine, and die-cast the cage at one time. The gate of the casting is turned on a lathe, but when die-casting an aluminum alloy cage, large-tonnage equipment is required, and the design and manufacture of the mold are complicated, and it is easy to strain the pocket of the cage during die-casting. [0004] The plastic casting method is t...
