Abstract
The invention discloses a kind of processing technology of bearing washer, a kind of production and processing technology of bearing ring is particularly disclosed.It is an object of the invention to provide a kind of production and processing method of bearing ring, the method can not only shorten the production cycle of bearing, but also can reduce the production cost of bearing, while also ensuring that the quality and environment of processed bearing ring be not contaminated.The present invention includes：Bearing steel；Get the raw materials ready；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 technology of bearing washer, the production and processing work of more particularly to a kind of bearing ring
Skill.
Background technology
The technological process of production bearing ring in the prior art is generally：Bearing steel → cushioning 6-7 hours parison (table temperature
1270 DEG C, MSO DEG C of ingot temperature) → slow cooling goes out to cheat pickling reconditioning after 60 hours；De heating (1120 DEG C -1160 DEG C of temperature) rolling Hs delay
Go out to cheat after when rushing 24/J alignment pickling reconditioning → be cut into material section → forging (swash thick → rush ZH expand zbe rolling rings) → annealing → cutting →
Quenching → tempering → grinding：Enter assembly building after items detection is qualified.The shortcoming of existing production technology is complex process, pollution ring
Border, the long processing time of bearing ring, it is more expensive to manufacture.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of production method of bearing ring, and the 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；Get the raw materials ready；Open die forging；Flaw detection；Rolling ring；Move back
Fire；Sample examination；Vehicle Processing；Heat treatment；Grinding.
The temperature of described open die forging is at 850 DEG C -1150 DEG C；
Described rolling ring temperature is at 1000-1280 DEG C；
Described annealing temperature is at 400-600 DEG C；
Described hardening heat：Bearing steel (GCrls) is 835-860 DEG C；Carburizing (GCrl5SIMn) is 810-840 DEG C；Tempering temperature
Spend is 160-180 DEG C.In order to be controlled to quality, chemical composition chemical examination is carried out during selection bearing steel.
The old technique standard to be reached, matter are fully achieved according to bearing ring obtained in production technology of the invention
Good control is measured, the technique shortens the production cycle of bearing ring, reduced the production cost of bearing ring, this
Invented technology is reasonable, simple, quality that is can guarantee that product, is particularly provided with pollutant emission.
