Description

Technical Field

[0001] The utility model relates to the technical field of die processing, in particular to a reaming die for bearing ring forgings. Background Technique

[0002] Existing bearing ring blank forgings are generally processed by a reaming machine to form a straight cylindrical forging finished product, and then through further processing, the straight cylindrical forging finished product is turned into a forging finished product with a spherical surface whose outer surface bends towards both ends and a groove on the inner surface. After the reaming operation on the bearing ring, it is necessary to grind the port position after reaming to maintain the smoothness of the inner ring.

[0003] The utility model document with the patent application number CN202222620324.8 discloses a bearing ring forging reaming die, belonging to the technical field of bearing processing. It includes a first motor, one end of the first motor is fixedly connected with a main gear, the main gear is meshed with the upper surface of the first rack, and one side of the first rack is fixedly connected with a first fixture. This device can easily fix the bearing ring through the arranged first fixture, second fixture and third fixture, and during the reaming process, the possibility of waste parts due to unstable fixation is avoided, ensuring the cost of bearing manufacturing.

[0004] The reaming die proposed in the above application document, during actual use, uses a reaming mechanism to perform directional support expansion on the inside of the bearing ring. However, this method not only easily causes the inner wall of the bearing ring after reaming to be not smooth, but also the roundness of the inner ring cannot be guaranteed, and it is impossible to achieve the effect of grinding and deburring the inner wall of the ring during reaming. Therefore, we have designed a reaming die for bearing ring forgings. Content of the Utility Model
