Bearing ring blank cold rolling follow-up supporting device

Abstract

The invention relates to the field of bearing ring manufacturing, and aims to provide a bearing ring blank cold rolling follow-up support device. A bearing ring blank cold rolling follow-up support device, including a rear plate and a fixed seat composed of a bottom plate and a side plate fixedly connected to one side of the rear plate, a pivoting arm connected to the rear plate, and the front end of the pivoting arm A support rod fixedly connected, a support block fixedly connected at one end to the lower side of the front end of the rotating arm, an oil cylinder fixedly connected to the bottom plate and the cylinder rod supporting the lower end of the support block, a side adjustment screw and a threaded connection with the side adjustment screw and connected to the rear plate The other side is fixedly connected to the adjusting nut; one end of the side adjusting screw passes through the rear plate and is opposite to the rear end of the support block. The bearing ring blank cold rolling follow-up support device does not need to break away from the support for the blank during cold rolling, and the bearing ring blank has good roundness.

Description

technical field [0001] The invention relates to the field of bearing ring manufacturing, in particular to a bearing ring blank cold rolling follow-up support device. Background technique [0002] The structure of the bearing ring cold rolling device can be understood from the utility model of a short cylindrical roller bearing outer ring cold rolling machine disclosed in the Chinese patent announcement number CN202291177U; the short cylindrical roller bearing outer ring cold rolling machine is the bearing ring Blank cold rolling machine; when the blank of the bearing ring blank enters the cold rolling position, the bearing ring blank cold rolling support device is required to support the positioning of the lower side of the outer circumference of the blank; the general bearing ring blank cold rolling support device is due to the cold rolling of the blank The diameter gradually expands under the interaction of the rolling wheels located outside the side wall of the blank and ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to overcome the disadvantages of the current support device for cold rolling of bearing ring blanks that need to be separated from the support of the blank during cold rolling, and the roundness of the bearing ring blank is poor, and to provide a device that does not need to separate from the support of the blank during cold rolling. Support, bearing ring blank cold rolling follow-up support device with better roundness of bearing ring blank
