The invention relates to processing equipment and a production process for a thrust bearing without an outer ring. The processing equipment comprises primary punch forming equipment, secondary punch forming equipment, and buckling and pressing equipment, wherein the primary punch forming equipment consists of a punch press, an uncoiling machine and a coiling machine, the secondary punch forming equipment consists of a punch press, the punch press of the primary punch forming equipment is fixedly provided with a forming die, the primary forming die comprises an upper die holder and a lower die holder which are arranged in a pairing way, the upper die holder is sequentially and fixedly provided with a center hole punching cutter, an outer cutting edge punching cutter and a forming punching head, positioning hole punching cutters are annularly distributed around the center hole punching cutter, and the bottom end of the forming punching head is provided with an annular press head. The novel processing and production equipment for the thrust bearing without the outer ring has the advantage that the solid foundation is provided for the mass production of the thrust bearing without the outer ring.
Description
Technical field: [0001] The invention relates to the technical field of bearing production, and more specifically relates to a processing equipment and a production process of a thrust bearing without an outer ring. Background technique: [0002] At present, a thrust bearing without an outer ring is used when rotating in an automobile rearview mirror. The thrust bearing is only composed of a cage and steel balls. The steel balls are clamped on the cage after forming and crimping, so this cage is a newly developed bearing product, and there is no complete set of processing equipment for manufacturing this kind of bearing in the market at present. Invention content: [0003] The purpose of the present invention is to provide a processing equipment and production technology for a thrust bearing without an outer ring, which can produce and process a new type of thrust bearing without an outer ring. [0004] Technical solutions of the present invention are as follows: [0005...
