Description
Technical field
The present invention relates to steel ball production field, more particularly to a kind of accurate steel balls automatic polishing technique.
Background technology
, it is necessary to by cold-heading, photosphere, heat treatment, hard grind, slightly grind, detect a flaw, lappingout and cleaning in the manufacturing process of steel ball
Etc. several big processes.After slightly process is ground, it is sent into before flaw detection process, it is necessary to which preferred clean to steel ball surface, to remove
The particles such as the mill slag of influence quality of surface adhesion and lapping liquid, meanwhile, steel ball appearance defect can be checked in time, prevent from grinding
Slag, lapping liquid enter next procedure.
Current traditional polishing process is still carried out oil removing polishing, made using traditional three step glossings, i.e. corncob
With sodium oleate soap heat scalding and boil, be polished production with cloth angle again, this glossing surface brightness reaches wanting for flaw detection
Ask, but cleannes do not reach requirement, and the greasy dust of cloth brings larger puzzlement to flaw detection management and production, influences the effect of flaw detection,
Simultaneously the shortcomings that larger in terms of environmental management being present：1st, the largely solid waste such as useless corncob, useless cloth angle is produced；2nd, make an uproar
Sound is big；3rd, it is short to scald boil liquid service life, once all left and right failures, not only high processing costs, and waste liquid is difficult to handle, can not return
Receive and utilize.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of accurate steel balls automatic polishing technique, technological requirement is being ensured
On the basis of, the greasy influence of cloth is reduced, reduces the pollution to environment, and eddy current inspection can be fully met steel ball surface is cleaned
Degree, the requirement of brightness.
In order to solve the above technical problems, the technical scheme is that：A kind of accurate steel balls automatic polishing technique, it is innovated
Point is：Including cleaning and unifying automatically steel ball surface, the automatic blanking progress phase of air knife one water removal, baking of being rolled into special air blade
Do three steps.
Further, the step is specially：
a）Cleaning and automatically unified steel ball surface：First, pending steel ball is put into cleaning cylinder, the cleaning cylinder is one
The hollow cylindrical structure of upper end open, have a cleaning delivery port, then, add into cleaning cylinder in the bottom of cleaning cylinder
Enter the oil removing cleaning that degreaser first carries out single order section to steel ball, after the completion of cleaning, from the delivery port of cleaning cylinder by degreaser
Discharge, then clear water is added into cleaning cylinder, the clear water that the two-stage is carried out to steel ball cleans；
b）Automatic blanking carries out the water removal of the phase of air knife one：Steel ball after two-stage cleaning, which is sent into separating sieve, carries out size of different sizes
The screening process of steel ball, while during screening, pre cleaning is carried out to the surface water of steel ball using air knife；
c）Roll and dry into special air blade：Steel ball after pre cleaning is delivered on conveying crawler belt and conveyed, in the process of conveying
In, carry out drying and processing to steel ball using the heating tube for being arranged on conveying crawler belt lower end, the temperature of drying for 115-130 DEG C it
Between, the time of drying is 14-16min, while during drying, using being arranged on the air knife of conveying crawler belt upper end to steel ball
Rolled, the temperature for the wind that air knife is blown out is 80 DEG C.
Further, in the step a, duration of the oil removing in stage cleaning is 2-3min, the clear water of two-stage
The duration of cleaning is 1-2min.
Further, in the step b, the temperature that air knife carries out pre cleaning is 80 DEG C.
Further, in the step b, the separating sieve includes
One steel ball buffer unit, the steel ball buffer unit are arranged on the discharge port end of heat-treatment production line, including a receiver,
It is provided with striker plate at the both ends of receiver, the receiver has several in yi word pattern and the discharging opening of column distribution；
One sieve unit, the sieve unit are arranged on the discharge port end of receiver, including a pair of the discharging opening 1 with receiver
The screening group answered, every group of screening group are collectively formed by the screening bar of two and column distribution, and appearance steel ball is left between two screening bars
The gap passed through, and the gap between two screening bars can be adjusted by governor motion；
One splicing unit, the splicing unit are included positioned at the small-bore steel ball picking-up container A sieved below bar and positioned at screening bar
The heavy caliber steel ball picking-up container B of side.
Further, the governor motion include with any driving cylinder for being connected of screening bar in each screening group, and can be by
Driving cylinder driving is away from or close to the same as another screening bar in group.
Further, the governor motion includes a gangbar, and the gangbar is with being located at the same side in each screening group
Screening bar is connected, and the gangbar is driven along the distribution arrangement of screening group by driving cylinder and moved back and forth.
Further, it is provided with baffle plate on the outside of two screening bars in every group of screening group.
Further, in the step c, heating tube is a S-shaped tubulose knot extended along the conveying direction of conveying crawler belt
Structure.
The advantage of the invention is that：In the present invention, by being improved to traditional polishing, justify first with cleaning
Cylinder cleans to steel ball, recycles air knife A to carry out pre cleaning to steel ball surface water, and finally carrying out surface residual water to steel ball enters
Row drying, and steel ball is rolled using air knife B during drying, ensure drying effect, using above-mentioned this processing
Technique, it can reduce the greasy influence of cloth on the basis of technological requirement is ensured, reduce the pollution to environment, and can expire completely
Sufficient eddy current inspection is to steel ball surface cleannes, the requirement of brightness.
By the setting of tipping mechanism, cylinder upset will can be entirely cleaned, will fall the steel ball cleaned in cylinder so as to convenient
Enter next procedure.
Setting for separating sieve, using bar is sieved to being sieved by steel ball, by two kinds of steel ball sieves of different size
Branch away, and classification storage, it would be desirable to the steel ball of bore deliver to later process and be processed, so as to effectively avoid from
Heat-treatment production line is delivered in the steel ball in next procedure there is two kinds of specifications, influences being smoothed out for processing.
Setting for governor motion, independent regulation can be carried out by the corresponding screening bar of a driving cylinder,
Regulation can be synchronized to all screening bars using a driving cylinder, can according to specific operating mode unrestricted choice, so as to
Realize the variation of regulation.
By screening bar outside set baffle plate, steel ball can be avoided when by sieving bar, bigbore steel ball from
Side is fallen in small-bore steel ball picking-up container A, it is ensured that the steel ball in picking-up container is same specification.
In the present invention, for the setting of heating tube, by being designed to extend along the conveying direction of conveying crawler belt
S-shaped tubular structure, also for uniformly being heated to the steel ball that conveys on conveying crawler belt, it is ensured that heating effect.
