Abstract
The invention discloses a production process of a high-precision ball bearing ring and belongs to the technical field of machine manufacturing. The process comprises the following steps of: machining a blank into a ring by use of a machine tool; performing cold-rolling expansion treatment to primarily shape the ring; performing heat treatment and cryogenic treatment under such conditions that the quenching hardness of heat treatment reaches the level HRC60-63 and the cryogenic temperatures is controlled within the range of minus 60 DEG C to minus 90 DEG C; after cold-rolling expansion treatment, performing raw grinding treatment and fine grinding treatment on the planes, outer circumference, inner cavity and channels of the ring until the dimensional precision of a component is reached; and finally performing ultra-fine grinding treatment on the channels of the bearing ring so as to reduce the roughness of the channels, improve the roundness of the channels and ensure that the roughness is less than 0.015 Ra. According to the invention, the production process is simple, the production period is shortened, and the production efficiency is increased; and besides, the cold-rolling expansion treatment ensures that the fatigue resistance and precision of the bearing ring are improved, so that the service life of the bearing ring is longer.
Description
Technical field
The present invention relates to a kind of production technology of ball bearing race, concrete relate to a kind of production technology that is applied to the high-precise ball bearing ring under the condition of running up, belong to machinery manufacturing technology field.
Background technology
Bearing is widely used in the civilian nearly all industries of national defence such as machine-building, Aero-Space, communications and transportation, the energy, electric power, mining, metallurgy, building, chemical industry, IT, household electrical appliances.Bearing is made up of inner and outer ring, rolling element and retainer etc. usually, characteristics such as that its each parts all should have is wear-resisting, corrosion-resistant, endurance, shock resistance, high roughness and high dimensional accuracy.The technical process of now commonplace production ball bearing race comprises that Vehicle Processing (plane, external diameter, endoporus, raceway groove, eight place's chamferings), heat treatment, mill are processed (plane, external diameter, endoporus, raceway groove), raceway groove is super smart, whole flow process mainly is that Vehicle Processing is more loaded down with trivial details, and the ball bearing race precision of processing is not high, stock utilization is low, the production cycle is long, production efficiency is low, manufacturing cost is high.
Summary of the invention
In view of the defective that prior art exists, the purpose of this invention is to provide the production technology of the ball bearing race that a kind of production cost is low, with short production cycle, production efficiency is high and machining accuracy is high.
For achieving the above object, the present invention solves by the following technical programs: a kind of production technology of high-precise ball bearing ring, adopt lathe that the blank Vehicle Processing is circularized; Carry out cold roll and expand technology, with the basic machine-shaping of lasso; Heat treatment and subzero treatment: heat-treatment quenching hardness HRC60-63, cryogenic temperature are controlled at subzero 60 ℃ to subzero 90 ℃; The workpiece that expands technology through cold roll carries out preliminary grinding and fine grinding technology, and plane, external diameter, endoporus, the raceway groove of lasso ground processing, reaches the dimensional accuracy of part; Carry out the fine abrasive operation at last, the raceway groove of bearing ring is carried out fine abrasive, reduce the roughness of raceway groove and improve the circularity of raceway groove, its roughness is less than 0.015Ra.
Adopted cold rolling technology, the effect that described cold rolling is expanded is to reduce the Vehicle Processing operation, shortens the production cycle, enhances productivity, and cuts down the consumption of raw materials.If adopt common cutting working method to make, the utilization rate of material is generally 40%-50%, and with the method for cold rolling expansion, its stock utilization then can reach 70%-80%.
Production process of the present invention is simple, has shortened the production cycle, has improved production efficiency, and fatigue durability and the precision that operation has improved bearing ring expanded in simultaneously cold rolling, makes the longer service life of bearing ring.Precision cold rolled expansion processing technology be a kind of less, do not have the new technology of cutting because precision cold rolled expansion can make workpiece shape and precision approach the shape and the precision of fabricated part to greatest extent, and can significantly improve the inherent quality of workpiece, save raw material significantly.Cold rolling is expanded and is carried out on ring rolling machine, the one stroke of lathe just can finish tangible processing, substituted the Vehicle Processing operation fully, can increase substantially labor productivity.Improve the mechanical performance of part: after the cold spreading distortion, the grain structure of metal material is fine and close more, and metal streamline is constant, does not cut off, so the fatigue resistance of material improves.
The specific embodiment
A kind of production technology of high-precise ball bearing ring adopts lathe that the blank Vehicle Processing is circularized; Carry out cold roll and expand technology, with the basic machine-shaping of lasso; Heat treatment and subzero treatment: heat-treatment quenching hardness HRC60-63, cryogenic temperature are controlled at subzero 60 ℃ to subzero 90 ℃; The workpiece that expands technology through cold roll carries out preliminary grinding and fine grinding technology, and plane, external diameter, endoporus, the raceway groove of lasso ground processing, reaches the dimensional accuracy of part; Carry out the fine abrasive operation at last, the raceway groove of bearing ring is carried out fine abrasive, reduce the roughness of raceway groove and improve the circularity of raceway groove, its roughness is less than 0.015Ra.
Adopted cold rolling technology, the effect that described cold rolling is expanded is to reduce the Vehicle Processing operation, shortens the production cycle, enhances productivity, and cuts down the consumption of raw materials.If adopt common cutting working method to make, the utilization rate of material is generally 40%-50%, and with the method for cold rolling expansion, its stock utilization then can reach 70%-80%.
