The invention relates to a technology for processing a spherical roller of a roller bearing, specifically relates to a technology for processing a spherical roller of an extra large size bearing and belongs to the field of bearing manufacturing. The technology includes feeding, finish turning of two end surfaces, carburization heat treatment, grinding of double end surfaces, coarse grinding of outer diameters, fine grinding of the outer diameters, flaw detection and demagnetization treatment, the technology is simple and obvious in effect, a grinding diameter of a centerless grinding machine is changed to broaden processing ranges of workpieces and improve production efficiencies, production indexes are up to advanced national standards, and high-accuracy production requirements of the roller bearing are completely met; and simultaneously, by means of the technology, the failure ratio is low, labor intensity is reduced, maintenance costs are reduced, and the application prospect is wide.

Description

Extra large size bearing spherical roller processing technology
Extra large size bearing spherical roller processing technology
Technical fieldThe present invention relates to a kind of roller bearing spherical roller processing method, specifically relate to extra large size bearing spherical roller processing technology, belong to bearing and make the field.
Background technologyMake the field at bearing, general roller mainly all adopts instrument lathe and centerless grinder to process.Lathe refers to that take workpiece rotating as main motion lathe tool moves the lathe into feed motion processing rotary surface, and it can be used for processing various rotation-formed.But many engine lathe diameter lengths are limited, break down easily when the hydraulic pressure feeding, strengthen labour intensity, and production efficiency is low, and increase maintenance cost.Simultaneously, without be careless or thoughtless by nature, during fine grinding, its grinding machine maximum grinding diameter less, its range of work is little, affects production efficiency.
Summary of the inventionThe present invention is in order to remedy above-mentioned technological deficiency, a kind of extra large size bearing spherical roller processing technology to be provided, and this technique enlarges the range of work of workpiece by changing the grinding diameter of centerless grinder, enhances productivity, and product index reaches national advanced standard.
To achieve these goals, technical scheme of the present invention is: extra large size bearing spherical roller processing technology, and concrete processing technology step is as follows:
1, feeding: to the external diameter sizing, blanker cuts bar;
2, finish turning both ends of the surface: both ends of the surface are carried out finish turning by lathe;
3, carburizing heat treatment: make the hardness of product and metallographic structure reach designing requirement and standard, hardness HRC59-63,3 grades of metallographic structures;
4, mill Double End: carry out the secondary cross grinding by grinding machine;
5, corase grind external diameter: by grinding machine external diameter is roughly ground five times, external diameter is 0.18-0.22mm;
6, fine grinding external diameter: external diameter is carried out fine grinding secondary, 0.07-0.10mm by grinding machine;
7, flaw detection;
8., demagnetization;
9., smart, mill carries out essence, whole mill three times at last eventually, reaches drawing requirement size and form and position tolerance, roughness requirement;
10, inspection is carried out visual examination, is surveyed magnetic, grouping product eventually;
11, oiling, packing: product is carried out the antirust processing of oiling.
Beneficial effect of the present invention is: technique of the present invention is simple, and successful is by changing the grinding diameter of centerless grinder, enlarge the range of work of workpiece, enhance productivity, product index reaches national advanced standard, satisfies the made with high precision demand of roller bearing fully; Adopt simultaneously this technology trouble rate low, reduce labor intensity, reduce maintenance cost, application prospect is extensive.
The specific embodiment
The below is the specific embodiment of the present invention.
Extra large size bearing spherical roller processing technology, concrete processing technology step is as follows:
1, feeding: to the external diameter sizing, blanker cuts bar;
2, finish turning both ends of the surface: both ends of the surface are carried out finish turning by lathe;
3, carburizing heat treatment: make the hardness of product and metallographic structure reach designing requirement and standard, hardness HRC59-63,3 grades of metallographic structures;
4, mill Double End: carry out the secondary cross grinding by grinding machine;
5, corase grind external diameter: by grinding machine external diameter is roughly ground five times, external diameter is 0.18-0.22mm;
6, fine grinding external diameter: external diameter is carried out fine grinding secondary, 0.07-0.10mm by grinding machine;
7, flaw detection;
8., demagnetization;
9., smart, mill carries out essence, whole mill three times at last eventually, reaches drawing requirement size and form and position tolerance, roughness requirement;
10, inspection is carried out visual examination, is surveyed magnetic, grouping product eventually;
11, oiling, packing: product is carried out the antirust processing of oiling.
