Bearing ring blank cold-rolling machine

Abstract

The invention relates to the field of bearing manufacturing equipment, and aims to provide a cold rolling machine for blanks of bearing rings. A cold rolling machine for blanks of bearing rings, comprising a bottom box with a rear plate at the upper end, a core roller device connected to the upper end of the bottom box through at least one small slide rail and equipped with a core roller, and a The rolling wheel that cooperates with the core roll to roll the billet and is connected to the rear plate, the support wheel device and the drive device that are located on the right side of the core roll device and connected to the upper end of the bottom box through at least one large slide rail, located on the core The billet support device and discharge channel on the lower side of the roller, the feeding device and the measurement and control device on the upper side of the core roller. The inner structure of the bearing ring blank processed by the cold rolling machine of the bearing ring blank is compact, the service life is long, and the metal processing allowance is small.

Description

technical field [0001] The invention relates to the field of measuring devices for manufacturing bearing blanks, in particular to a cold rolling machine for bearing ring blanks. Background technique [0002] Generally, bearing ring blanks are made by casting or forging; the invention of Chinese patent notification number CN 1243207A discloses a production method of rolling bearing ring blanks; in particular, it relates to the application of centrifugal casting technology in the manufacturing process of rolling bearing ring blanks. Casting or forging can reduce the production cost of bearing ring blanks, but there are shortcomings in that the internal structure of bearing ring blanks is not dense enough, the service life is short, and the metal processing allowance is large; therefore, a processing The inner structure of the bearing ring blank is compact, the bearing ring blank cold rolling machine with long service life and small metal machining allowance has become an urgen...
