Abstract
The invention discloses a kind of processing technologys of bearing washer, especially disclose a kind of production and processing technology of bearing ring.The purpose of the present invention is to provide a kind of production and processing method of bearing ring, this method can not only shorten the production cycle of bearing, but also can reduce the production cost of bearing, while also ensure that the quality of processed bearing ring and environment be not contaminated.The present invention includes: bearing steel；Stock；Open die forging；Flaw detection；Rolling ring；Annealing；Sample examination；Vehicle Processing；Heat treatment；The processing technology of the bearing washer of grinding.
Description
Technical field
The present invention relates to a kind of processing technologys of bearing washer, more particularly to a kind of production and processing work of bearing ring
Skill.
Background technique
The process flow for producing bearing ring in the prior art is general are as follows: bearing steel → parison (the table temperature of cushioning 6-7 hours
1270 DEG C, MSO DEG C of ingot temperature) go out hole pickling reconditioning after → slow cooling 60 hours；It is slow that de heats (1120 DEG C -1160 DEG C of temperature) rolling H
Go out alignment pickling reconditioning → be cut into material section in hole after when rushing 24/J → forging (swash thick → rush ZH and expand zbe rolling ring) → annealing → cutting →
Quenching → tempering → grinding: enter assembly building after items detection is qualified.The shortcomings that existing production technology is complex process, pollution ring
Border, the long processing time of bearing ring, manufacturing cost are high.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of production method of bearing ring, this method can not only shorten
The production cycle of bearing, but also the production cost of bearing can be reduced, while also ensuring the quality of processed bearing ring
It is not contaminated with environment.
The processing technology of bearing washer of the present invention includes: bearing steel；Stock；Open die forging；Flaw detection；Rolling ring；It moves back
Fire；Sample examination；Vehicle Processing；Heat treatment；Grinding.
The temperature of the open die forging is at 850 DEG C -1150 DEG C；
The rolling ring temperature is at 1000-1280 DEG C；
The annealing temperature is at 400-600 DEG C；
The hardening heat: bearing steel (GCrls) is 835-860 DEG C；Carburizing (GCrl5SIMn) is 810-840 DEG C；Tempering temperature
Degree is 160-180 DEG C.In order to control quality, select to carry out chemical component chemical examination when bearing steel.
Bearing ring made from production technology according to the invention fully achieves the attainable standard of old technique institute, matter
Good control has been measured, which shortens the production cycle of bearing ring, the production cost of bearing ring is reduced, this
Invented technology rationally, quality that is simple, can guarantee product, be particularly provided with pollutant emission.
