Description
Technical field
The invention belongs to bearing steel ball processing technique field, in particular to the processing technology and production of a kind of bearing steel ball
Line.
Background technique
Steel ball is divided into grinding steel ball, forged steel ball, steel ball casting according to production and processing technology.It is divided into axis according to rapidoprint
Hold steel ball, stainless steel ball, carbon steel balls etc..Wherein bearing steel ball is the important foundation components of industry.
Bearing steel ball processes raw material as bearing steel wire rod, and existing bearing steel ball processing technology successively includes bracing wire, cold
Upsetting, photosphere, heat treatment, hard grind, lappingout, cleaning, appearance detection.
Bearing steel obtains ball embryo after bracing wire, cold-heading, and ball embryo removes the outer band and two poles of ball embryo after photosphere, passing through
Overheating Treatment enhances ball embryo hardness, then by hard grind, lappingout obtains smooth surface and size and the matched bearing of desired size
Steel ball, then by washing away the spot on bearing steel ball, last he is detected by appearance, picks out defect ware.
Bearing steel is easy to appear the useless ball embryo that part minimum diameter is less than desired size in bracing wire, cold-heading, these useless balls
Embryo due to there is diameter to be less than the part of desired size thereon, it is difficult to be made up by technique, the axis finally processed by the ball embryo that gives up
Holding steel ball also must be defect ware.But processed by above-mentioned technique, useless ball embryo also passes through complete process processing, wastes life
Cost is produced, the efficiency of production certified products is reduced.
Summary of the invention
In view of the deficiencies of the prior art, the present invention intends to provide a kind of processing technology of bearing steel ball,
The ball embryo size of bearing steel ball is screened between photosphere and heat treatment, selects and remove the bad shot that radius is less than desired size
Embryo avoids the waste for bad shot embryo being processed and being caused manufacturing cost, improving production efficiency.
Above-mentioned technical purpose of the invention has the technical scheme that a kind of processing work of bearing steel ball
Skill successively includes: bracing wire: bearing steel wire rod being pulled into required line footpath and obtains bearing steel wire；
Cold-heading: being placed in cold headers for bearing steel wire, breaks into ball embryo by punching block in machine；
Photosphere: ball embryo is put into ball grinder processing, removes the outer band and two poles of ball embryo surface；
Heat treatment: it is tempered quenching after carbunse is subject in ball embryo loading heat-treatment furnace again；
Hard grind: ball embryo is put into grinder, hard grind is carried out to ball embryo；
Lappingout: ball embryo is put into grinder, ball embryo is refined to obtain bearing steel ball；
Polished and cleaned: bearing steel ball is put into polishing machine polishing, then is cleaned by cleaning machine；
Appearance detection: bearing steel ball surface blemish, out of roundness and surface roughness are checked；
It further include screening between the photosphere and heat treatment, screening removal radius is less than the bad shot embryo of desired size.
By using above-mentioned technical proposal, bearing steel wire rod is pulled by required line footpath by bracing wire and obtains bearing steel wire, so
Bearing steel wire is placed in cold headers afterwards, ball embryo is broken by punching block in machine, ball embryo is put into ball grinder processing, removal ball embryo surface

As shown in figure 5 and figure 10, close to one end of cleaning machine 4, sliding is provided with gate 91, the second guide rail to the second guide rail 73
It is provided on 73 and opens a sluice gate cylinder 92, the piston rod for opening a sluice gate cylinder 92 is fixedly connected with gate 91.
Use principle:
Even machine drawing, cold headers, ball grinder obtain the ball embryo of bearing steel ball after successively handling, and ball embryo is placed in loading guide 12
On, ball embryo is rolled along loading guide 12 and is fallen on two sieve rollers 13, and is rolled along sieve roller 13 to the direction far from loading guide 12
Dynamic, since the screen slot 14 between sieve roller 13 is gradually increased, size diameter is less than the ball embryo of screen slot 14 from rolling from screen slot 14
Place is fallen, and achievees the purpose that screening.
When for that can be adjusted by regulating part 2 when screening various sizes of ball embryo.Cylinder is adjusted by starting
23, the piston rod for adjusting cylinder 23 drives two drive rods 24 to rotate and moves together with piston rod, and drive rod 24 pulls corresponding
First adjusting slider 22 it is close to each other perhaps separate so that sieve roller 13 end it is close to each other or separate, reach adjusting
The purpose of 14 size of screen slot.
After bearing steel ball in polishing machine 3 completes polishing, blanking lid 36 is opened, bearing steel ball is fallen from discharge port 35
It is fallen into elevating hopper 72 on to the first guide rail 71 and along the first guide rail 71.Bearing steel ball quantity in elevating hopper 72 increase so that on
72 total weight of hopper gradually increases, and compresses support spring 74, meanwhile, the elongation of adjustable spring 81 makes guide pad 76 by along the chute 77
To the trend slided and rotated far from 74 direction of support spring.But since convex block 87 and spherical guide block 84 are stuck in drive hole 83
In, cause elevating hopper 72 that can only move down vertically.
When moving down, spherical guide block 84 and convex block 87 are gradually increasing and with bearing steel ball number relative to 83 height of drive hole
The increase of amount, convex block 87 and card slot 86 are detached from and spherical guide block 84 enters in rotation cavity 78.At this point, elevating hopper 72 occurs to turn
It is dynamic, so that the bearing steel ball on elevating hopper 72 rolls down on the second guide rail 73.When the bearing steel ball on elevating hopper 72 reduces, on
The rotation of hopper 72 and rise, realize and reset.
Bearing steel ball on second guide rail 73 is not opened due to gate 91 to be accumulated on the second guide rail 73, and cylinder is opened a sluice gate in starting
92 drive gate 91 to open, so that bearing steel ball is fallen on the conus portion 55 in cleaning machine 4, and tumble along conus portion 55 into clear
Wash channel 54.When bearing steel ball is in flushing channel 54, receive flexible liner 53 compresses and rubs against realization cleaning, cleaning
Effect is good.When bearing steel ball is fallen on after falling in flushing channel 54 on discharge tray 6 and is rolled to blanking by feed opening 64
On track 65, finally it is rolled in aggregate bin 66 along blanking track 65.Water can be added when cleaning into flushing channel 54, to mention
Cleaning effect is risen, water flow is flowed out after entering aggregate bin 66 by drainage hole 67.
This specific embodiment is only explanation of the invention, is not limitation of the present invention, those skilled in the art
Member can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but as long as at this
All by the protection of Patent Law in the scope of the claims of invention.
