Bearing ring blank cold-rolling machine

Abstract

The invention relates to the field of bearing manufacturing equipment and aims to provide a bearing ring blank cold-rolling machine. The bearing ring blank cold-rolling machine includes a bottom box, a core roller device, a rolling wheel device, a supporting wheel device, a driving device, a blank supporting device, a discharge channel, a feeding device and a measuring and control device, wherein the upper end of the bottom box is provided with a rear plate, the core roller device is connected with the upper end of the bottom box through at least one small sliding rail and provided with a core roller, the rolling wheel device is located on the left side of the core roller device, provided with rolling wheels cooperated with the core roller in blank rolling, and connected with the rear plate, the supporting wheel device and the driving device are located on the right side of the core roller device and are connected with the upper end of the bottom box through at least one big sliding rail, the blank supporting device is located on the lower side of the core roller, a discharge channel is formed in the lower side of the core roller, and the feeding device and the measuring and control device are located on the upper side of the core roller. A bearing ring blank processed by the bearing ring blank cold-rolling machine is dense in interior texture, long in service life and small in metal machining allowance.

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...
