The production method has the advantages that production steps are clear, staffs perform their duties, use rate, production efficiency of the staffs are greatly improved, error rate of the staffs is decreased, and economic cost is lowered.
Description
Technical field
The present invention relates to machine-building processing technique field, the concrete manufacturing process that relates to a kind of rolling bearing.
Technical background
Rolling bearing is the connector between a kind of rotating shaft and static axle bed, is to reduce the friction loss accurate machine components of raising the efficiency, be therefore widely used with various machinery in.The citation form of rolling bearing is by an outer ring, an inner ring, one group of rolling element and retainer composition.Because rolling bearing structure is simple, be convenient to large batch of production.This inventor is researched and developed to a kind of production technology of rolling bearing.This production technology can be enhanced productivity greatly, reduces financial cost.
Summary of the invention
The object of the present invention is to provide a kind of production technology of rolling bearing, adopt the advantages such as the bearing friction coefficient that this explained hereafter efficiency is high, financial cost is few, produce is little, physical life is long.
Based on above object, a kind of production technology of rolling bearing has been proposed, its processing step is:
(1) procedure of processing of outer ring and inner ring is: first forged material is bar or the materials in the tube of the high carbon bearing steel of GCr9, and to the crude green body annealing after forging, next carries out turning processing, and to the semi-finished product heat treatment of turning processing, then grinding obtains inner ring and outer ring;
(2) roller procedure of processing is: first, by photosphere processing after raw material cold-heading molding, then heat-treat, refining and grinding obtains rolling element;
(3) procedure of processing of retainer is: first raw material is carried out to preliminary machined and obtain crude green body, then crude green body is heat-treated, to carrying out grinding through heat treated part;
(4) inner ring processing, outer ring, roller and retainer are checked and antirust processing;
(5) inner ring, outer ring, roller and retainer are assembled, then packaging warehouse-in.
Further, the processing step that forges bar in described rolling bearing production technology in Internal and external cycle procedure of processing is: the bar or the materials in the tube that first in electric furnace, heat bearing steel, secondly carry out blanking according to the suitable blanking tool of bar size Selection, then adopt extrusion forming process that blank forging is become and Internal and external cycle similar shape.Can save greatly like this material and raise the efficiency.
Further, in described rolling bearing production technology, in Internal and external cycle procedure of processing, the condition of annealing process is 800 DEG C of insulations 2 hours, is chilled to below 650 DEG C the air cooling of coming out of the stove with the time of 5 hours.Guarantee that for the ease of turning processing below its hardness is not more than 200HBS.
Further, in described rolling bearing production technology, in Internal and external cycle procedure of processing, be the oil quenching of 800 DEG C and the lonneal of 160 DEG C to the half-finished heat treatment after turning processing, guarantee that the hardness of heat treatment Internal and external cycle is afterwards not less than 63HRC.
Further, in described a kind of rolling bearing production technology, installation step is: to the capable degaussing of parts assembling, after assembling, check play demagnetizing, antirust processing, finally by crossing vacuum packing machine packaging warehouse-in.Be the coefficient of friction that reduces bearing in the effect of this twice demagnetization, improve physical life and the reliability of bearing.
The bearing arrangement that adopts above-mentioned production technology to produce is simple, and service life and the precision of bearing increase, and step is clear and definite simultaneously, and Each performs its own functions for employee, improves greatly employee's utilization rate, production efficiency and reduced fault rate and then saved financial cost.
Detailed description of the invention
Below in conjunction with concrete example, the present invention is further described
A production technology for rolling bearing, the bearing of this explained hereafter is made up of outer ring, inner ring, retainer and roller.A kind of processing step of production technology of roller bearing is: the various raw materials of bearing are carried out to preliminary machined and obtain crude green body, crude green body is heat-treated, the heat treated part of process is carried out to the inspection eventually of grinding, part, the assembling of bearing, the packaging of bearing.
The procedure of processing of bearing outer ring and inner ring is: first forge bar or materials in the tube, to the crude green body annealing after forging, next carries out turning processing, to the semi-finished product heat treatment of turning processing, then grinding obtains inner ring and outer ring, finally checks that antirust processing etc. is to be assembled.
In the processing technology of bearing outer ring and inner ring, Forging Technology is first in electric furnace, to heat bar or the materials in the tube of bearing steel, secondly carry out blanking according to the suitable blanking tool of bar size Selection, then adopt extrusion forming process that blank forging is become to Internal and external cycle similar shape.
In the processing technology of bearing outer ring and inner ring, the condition of annealing process is 800 DEG C of insulations 2 hours, is chilled to below 650 DEG C the air cooling of coming out of the stove with 5 hours.Guarantee that for the ease of turning processing below its hardness is not more than 200HBS.
In the processing technology of bearing outer ring and inner ring, be the oil quenching of 800 DEG C and the lonneal of 160 DEG C to half-finished heat treatment, guarantee that the hardness of heat treatment Internal and external cycle is afterwards not less than 63HRC.
Roller procedure of processing is: first, by photosphere processing after raw material cold-heading molding, then heat-treating, refining and grinding obtains rolling element, is finally to check, antirust processing etc. are to be assembled.
