Description

Technical Field

[0001] This utility model relates to the field of bearing processing technology, specifically to a device for heat preservation rolling and forging of medium and heavy bearing rings. Background Technology

[0002] Bearings are essential components in modern machinery. Their main function is to support rotating parts of the machine, reduce the coefficient of friction during movement, and ensure rotational accuracy. Based on the frictional properties of the moving elements, bearings can be divided into two main categories: rolling bearings and sliding bearings. Rolling bearings are standardized and serialized, but compared to sliding bearings, they have larger radial dimensions, higher vibration and noise levels, and are also more expensive. Rolling bearings generally consist of four parts: an outer ring, an inner ring, rolling elements, and a cage. Based on the shape of the rolling elements, rolling bearings are further divided into ball bearings and roller bearings. A patent, patent publication number CN221388758U, discloses an anti-overlay forging device for bearing ring forging equipment. The device includes a forging die, with a die groove formed on the front end face of the die. A ejector pin sleeve, communicating with the die groove, is formed on the rear end of the die. An ejector pin is inserted into the ejector pin sleeve, and the front end of the ejector pin has a cylindrical head. A sensor mounting plate is fixedly connected to the upper side of the forging die. A proximity switch sensor is inserted and fixedly mounted on the front end of the sensor mounting plate, extending beyond the front end face of the forging die. A clamping sleeve opposite the proximity switch sensor is provided on the front side of the forging die. This device, based on the ejector pin triggering the sensor, can solve the overlay forging problem caused by the punch carrying away the bearing ring forging.

[0003] Regarding the aforementioned technologies, the inventors believe that the following defects exist: it is inconvenient to perform stamping and positioning operations on the parts during actual application, which affects the forging operation of the device and reduces the ease of use of the device.
