The invention discloses an assembling die for a cylindrical roller bearing integrated retainer. The assembling die comprises an upper die and a lower die, wherein the upper die is a cover plate; the lower die comprises a base and a guide baffle; the guide baffle is fixedly arranged on the base, and a plurality of through holes are uniformly distributed on the base; pressing heads are arranged in the through holes; and the upper ends of the pressing heads stretch out of the through holes. The assembling die for the cylindrical roller bearing integrated retainer is simple in structure and easy to realize, a punch acts on the cover plate, and the pressing heads of the assembling die act on the retainer, so that the assembling die generates elastic deformation, and a convex point is formed on the inner side of the end face of the retainer so as to lock the roller; and moreover, normal operation of the roller is not influenced, and the assembling die is convenient to operate, uniform in molding and low in rejection rate.
Description
technical field [0001] The invention relates to an assembly die, in particular to an assembly die for a cylindrical roller bearing integral cage. Background technique [0002] Cylindrical roller bearings, that is, the rolling elements are cylindrical roller bearings, which generally adopt an integral cage with an end-lock structure. The number of pockets set in this cage is the same as the number of rollers, and the two sides of each pocket are Each has a pair of indenter holes. During the assembly process, the indenter of the assembly die punches the material at the bottom of the indenter hole under the action of an external force, causing the material to undergo expected deformation, so as to lock the end face of the roller without affecting the roller. The purpose of the normal operation of the sub. However, the assembly molds currently used for the assembly of cages and rollers have the problems of complex structure, cumbersome operation, uneven molding, and high scrap ...
