Bearing outer ring machining process

Abstract

The invention discloses a bearing outer ring machining process including the first step of double forging, the second step of annealing, the third step of double turning, the fourth step of double quenching tempering, the fifth step of grinding machine machining, the sixth step of ring separation, the seventh step of turning, the eighth step of additional tempering and the ninth step of measurement and inspection. In the first step, bearing steel is selected as a raw material, then the bearing steel is placed in a heating furnace to be subjected to one-time heating processing, and the bearingsteel is cut into single material sections after heating is completed. By means of the bearing outer ring machining process, a traditional production process of a single bearing outer ring is changed,bearing outer rings which are combined together are machined and produced, stress concentration in the process of conducting forging on the material sections is facilitated, material section deformation caused by uneven stress in the forging process is avoided, and material saving is facilitated; and meanwhile, ellipses and warping of products are eliminated through a grinding machine, the damagerate of the products is decreased, and the situation that due to secondary machining and production, the work efficiency is reduced is avoided.

Description

technical field [0001] The invention relates to the technical field of bearing outer ring processing, in particular to a bearing outer ring processing technology. Background technique [0002] Bearings are an important component in contemporary machinery and equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. The bearing is generally composed of an inner ring, an outer ring, rolling elements and a cage. In the process of making the outer ring , Usually the outer ring is manufactured in a single production, the product has a short back extrusion height, and the pressure of the press is large, which is easy to cause deformation and waste materials. In the process of processing the outer ring, CNC machine tools are usually used to grind the end face and outer diameter of the product. For processing, this method is not conducive to removing the difference between the elli...

Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. The bearing is generally composed of an inner ring, an outer ring, rolling elements and a cage. In the process of making the outer ring , usually the outer ring is manufactured individually, the height of the reverse extrusion of the product is low, the press is stressed, it is easy to cause deformation, waste materials, and in the process of processing the outer ring, CNC machine tools are usually used to grind the end face and outer diameter of the product For processing, this method is not conducive to removing the ellipse and parallel difference formed by the product itself after quenching, and it is easy to cause damage to the workpiece. Therefore, secondary processing is required for the damaged work, which reduces work efficiency.
