Abstract
The invention relates to a machining-shaping process of a bearing ring, in particular to a production machining process of a bearing ring, which aims to provide a production machining method of a bearing ring. By using the method, the production period of a bearing can be shortened; the production cost of the bearing can be reduced; and the method can also ensure that the quality and the environment of the machined bearing ring are not polluted. The machining-shaping process of the bearing ring comprises bearing steel material preparation, open die forging, fault detection, ring rolling, annealing, sampling and testing, lathing, heat treatment and grinding.
Description
Technical field:
The present invention relates to a kind of bearing sleeve processing shaping technology, particularly relate to a kind of production and processing technology of bearing ring.
Background technology:
The technological process of producing bearing ring in the prior art is generally: bearing steel → cushioning 6-7 hour parison (1270 ℃ of table temperature, MSO ℃ of ingot temperature) → slow cooling goes out to cheat the pickling reconditioning after 60 hours; Go out to cheat alignment pickling reconditioning → be cut into material section → forgings (swash thick → expand the zbe stone roller towards ZH to encircle) → annealing → cutting → quenching → tempering → grinding after during de heating (1120 ℃-1160 ℃ of temperature) rolling H buffering 24/J: enter assembly building after every detection is qualified.The shortcoming of existing production technology is long processing time, the manufacturing cost height of complex process, contaminated environment, bearing ring.
Summary of the invention:
The technical problem to be solved in the present invention provides a kind of production method of bearing ring, this method not only can shorten the production cycle of bearing, but also can reduce the production cost of bearing, can also guarantee that the quality and the environment of the bearing ring processed is not contaminated simultaneously.
Bearing sleeve processing shaping technology of the present invention comprises: bearing steel; Get the raw materials ready; Open die forging; Flaw detection; Grind ring; Annealing; Sample examination; Vehicle Processing; Heat treatment; Grinding.
The temperature of described open die forging is at 850 ℃-1150 ℃;
Described stone roller ring temperature is at 1000-1280 ℃;
Described annealing temperature is at 400-600 ℃;
Described hardening heat: bearing steel (GCrls) is 835-860 ℃; Carburizing (GCrl5SIMn) is 810-840 ℃; Temperature is 160-180 ℃.For quality is controlled, to carry out the chemical composition chemical examination when selecting bearing steel.
The bearing ring that makes according to production technology of the present invention can reach the standard that old technology can reach fully, quality has obtained better controlled, this technology has shortened the production cycle of bearing ring, reduced the production cost of bearing ring, technology of the present invention rationally, simple, the quality that can guarantee product, be provided with pollutant emission especially.
