Abstract

The invention relates to a shaping device and method, and particularly relates to a bearing ring shaping device and method. The bearing ring shaping device and method aim at solving the problem that a molding pressing technology or a mold control deformation technology is difficult to realize in a quenching process of a bearing ring which is complicated in structure and changes greatly in wall thickness. The bearing ring shaping device comprises a main body frame, a lifting cross beam, two guide columns, two guide sleeves, two fixing cushion blocks, an instrument pedestal, a positioning table, a limited block, a jack and two adjustable vertical columns, wherein the two guide columns are vertically arranged in the main body frame side by side; the upper ends of the two guide columns are fixedly connected to the main body frame; and the lifting cross beam is horizontally arranged in the main body frame. The bearing ring shaping device and method belong to the field of bearing manufacturing.

Description

technical field [0001] The invention relates to a shaping device and method, in particular to a bearing ring shaping device and method, belonging to the field of bearing manufacturing. Background technique [0002] The heat treatment deformation of the bearing ring has a great influence on the product quality. Although it can be corrected through the heat treatment process, the shaping technology is also one of the effective measures to control the deformation. The structure of SG13Cr4Mo4Ni4V steel bearing ring is complex, and the wall thickness changes greatly. The quenching and tempering treatment of the ring after carburizing is all completed in a vacuum air quenching furnace. , It is difficult to realize molding or mold control deformation technology in the quenching process, and the ferrule shaping can only be achieved by rectifying or shaping methods before tempering, through martensite transformation and residual austenite transformation in the tempering process, to a...
