The surface of workpiece is cleared up by all angles.In the present embodiment, impeller head 31 is set to the throwing with workpiece
Firing angle degree becomes X °, and meets 25 °≤X °≤35 °；Meanwhile, relative two impeller head 31 is set
It is respectively A, B away from thin plate length, and meets A=B+40, wherein 700mm≤B≤900mm.Described
Impeller head 31 includes: impeller 311, conjoint disk 312, motor 313, shot wheel 314, orienting cover 315,
Blade 316, lead the components such as ball pipe 317, wear plate (3181,3182,3183), guard shield 319.Institute
Stating orienting cover 315 to be fixed in guard shield 319, it has a window, and can be by adjusting orienting cover
315 and adjust the direction of this window.The inside of orienting cover 315 is installed with shot wheel 314.Described point
On ball wheel 314, there are an entrance and four windows.Described ball pipe 317 of leading is positioned at the side of guard shield 319,
And this entrance of the one end and shot wheel 314 leading ball pipe 317 is connected, the other end connects for ball system (figure
In do not show), wherein, for ball system being provided with for ball lock, in order to regulate ball blast flow, and be easy to maintenance.
The opposite side of described guard shield 319 is provided with impeller 311, and described impeller 311 is provided with multiple blade 316,
Blade 316 is distributed in the periphery of orienting cover 315.Impeller 311 leads to the output shaft of motor 313
Cross conjoint disk 312 to be connected, and driven this impeller 311 to rotate by motor 313.Additionally, combining
Seal disc 3121 it is also equipped with between dish 312 and motor 313.It is also equipped with in described guard shield 319
For preventing the wear plate of ball blast excessive damage guard shield 319, wear plate includes being positioned at guard shield 319
Side roof part top backplate 3181, be positioned at the side guard plate 3182 of guard shield 319 inboard side edge and be positioned at guard shield 319
The end face protective plate 3183 of inner side end.During work, bullet is rolled in shot wheel 314 by leading ball pipe 317,
Presetting the window in direction through orienting cover 315 after preaceleration to dish out, blade 316 continues to accelerate it, enters
And adjust impelling and reach strength strike on workpiece, to reach the purpose of cleaning.Described impeller head 31 has
Simple in construction, easy to maintenance, take up room the advantage such as little, and blade 316 need not screw, pin, spring
Any fixtures such as card are fixed, but blade 316 inserts impeller groove (not shown) from impeller 311 center
In, the boss knot when impeller 311 is rotary, on the centrifugal force of dependence blade 316 generation and blade 316
Structure is fixed.
Described super shot blasting cleaning chamber 3 is multicell assembly, is made up of main chamber's body 32 and concubine body 33, its
In above-mentioned impeller head 31 be arranged on the outer wall of main chamber's body 32, before and after main chamber's body 32, both sides are pair
Chamber body 33, concubine body 33 be sealing chamber body and in be provided with steel plate and multilayer rubber curtain and shield, to prevent bullet
Ball disorderly flies.There is certain negative pressure in super shot blasting cleaning chamber 3 simultaneously, prevent dust from escaping.Described super shot blasting cleaning chamber
It is provided with wear resistant cast iron steel plate in 3, to protect chamber body wallboard from abrasion, extends chamber body decades of times in service life
Above；The reflection function of bullet, the strike surface of the work remained valid can be utilized simultaneously, improve cleaning matter
Amount and cleaning efficiency, equipped with net on cleaning taper collection ball bucket, to intercept foreign material, protect helical feed
Machine, it is simple to maintainer keeps in repair.In shot blast room body, backplate uses wear-resisting bag casting nut to hide and bolt, protection
Screw is without damage, and disassembling, assembling and replacing is convenient.Additionally, for preventing bullet from flying out, be provided with in super shot blasting cleaning chamber 3
Preventer.
In the present embodiment, this thin plate wheel abrator also includes separation 4, returns ball room 5, lift cylinder 6
With high pressure back blowing machine 7, wherein, go back to ball room 5 and be arranged at the lower end of described blowing device 1；And lifting air
Cylinder 6 is connected with described high pressure back blowing machine 7.
Sheet workpiece passes through transfer roller, enters ball blast region, opens each impeller head 31 by step and carries out
Ball blast.
In the case of making the upper and lower hitting dynamics of thin plate to be processed identical, first we will be to impeller head 31
To impelling angle X ° of workpiece, impeller head 31 away from thin plate length A, B be designed as it is shown on figure 3,
When experimentation proves impeller head 31 to the impelling angle 25 °≤X °≤35 ° of workpiece, effect is
Good.Because < when 25 °, ball blast dynamics is excessive, and the deflection of thin plate is excessive, it is impossible to reach work when X °
Skill requirement；When X ° > 25 ° time, ball blast cannot cover the surface of whole workpiece, it is impossible to meets a ball blast
Requirement.The cast of impeller head 31, concludes that A=B+40 according to design calculating, experiment, its
Middle 700mm≤B≤900mm.Verified, when B < during 700mm, impelling dynamics and within the specific limits
Cast is directly proportional, and impelling dynamics does not reaches requirement, it is impossible to make removing surface clean；Work as B > 900mm
Time, cast is excessive, and ball blast diversity is excessive, causes the shot of impeller head 31 impelling that opposite arranges
Mutually air exercise, causes waste greatly, and thin sheet surface there will be dark side, does not reaches requirement.Finally in order to
Making often to organize impeller head 31 upper and lower, left and right hitting dynamics consistent, residual stress of cancelling out each other, except meeting
Both the above parameter, also to regulate shot supply valve above, makes the consistent for ball amount of four impeller heads 31.
Arranging several groups of same impeller heads in the same way continuously, thin plate cleaning speed can be greatly improved.
It should be noted that above example only in order to technical scheme to be described and unrestricted, although ginseng
According to preferred embodiment, the present invention is described in detail, it will be understood by those within the art that, can
Technical scheme is modified or equivalent, without deviating from the essence of technical solution of the present invention
God and scope, it all should be contained in the middle of scope of the presently claimed invention.
