Description
Technical field
The present invention relates to the derusting technical fields of rail vehicles wheel pair, and railway locomotive vehicle is used for more particularly to one kind
Wheel pair derusting method.
Background technology
Railway freight-car is the important transportation instrument for completing railway transportation task, and the wheel of vehicle is to being that most important lorry is walked
One of row component.The generation of train travel accident all has direct relation with the repair quality of car wheel-set several times.The wheel of lorry
To before magnetic powder inspection, it is necessary to take turns to clearing up.The cleaning quality of igneous rock cracks will directly influence the result of magnetic powder inspection.
It is required, taken turns to after derusting is rinsed, outer surface must expose parent metal, outer surface should be without grease, rust according to lorry maintenance craft
Layer, next process of being allowed for access, and the existing derusting process to wheel pair, derusting is reached to polishing to wheel using abrasive band
Purpose, but since two sides of wheel are curved surface, abrasive band more completely can not carry out processing of rust removing to wheel, leave
Security risk.
The content of the invention
How the technical problems to be solved by the invention are to taking turns to more completely being derusted, and overcome lacking for the prior art
Point.
In order to solve the above technical problems, the present invention provides a kind of derusting method for rail vehicles wheel pair, bag
Include following steps：
A, wheel pre-processes surface, the greasy dirt to surface is taken turns in removal, and wheel is made to become the oxide layer and iron rust layer on surface
Loosely；
B, by wheel to being placed in shaft, and /V is carried out to both sides to wheel, will take turns mobile to the wire brush of both sides and takes turns offside
Side and wheel face contradict, and wheel sprays side and wheel face using high pressure water spray gun, and side and wheel face are sprayed
Angle between the injection direction of high pressure water spray gun is acute angle, and injecting time continues 35min, drying wheel pair, it is ensured that dries net wheel pair
The residual water on surface；
C, it by wheel to transporting to shot blast room, and will take turns to being placed on rotating wheel device, while start wheel-turning device and ball blast rifle, to wheel
To carrying out shotblasting；
D, wheel is cleared up into chamber to taking turns to cleaning to transport to pellet, is sprayed after cleaning using clear water, drying.
Technique effect：For the present invention first to wheel to carrying out surface preparation, removal wheel is miscellaneous to easy-clears such as the greasy dirts on surface
Matter, and make to be tightly adhered to take turns and loose is become to the oxide layer and rusty scale on surface, make oxide layer and rusty scale wheel pair easy to fall off, then will
Wheel can be freely rotated it to preventing in shaft, and both sides and wheel face are contradicted by wire brush, and to side and wheel face into
Angle between the injection direction of the high pressure water spray gun of row injection is acute angle, when high pressure water spray gun works, can will be taken turns to table
The loose oxide layer in face and rusty scale wash out, while can promote wheel to being rotated to a direction, while wheel is to rotating, wire brush
It can polish the side of wheel pair and wheel face, further the oxide layer and rusty scale of upper attachment be filled by wheel, in addition, using high
It cooperates between pressure water pistol and iron wire brush, the scavenging period to wheel pair can be shortened, and cleaning performance is provided, in addition, again
To wheel to carrying out Shot Blasting, it can will remain in wheel and wheel pair, and Shot Blasting are completely disengaged to the oxide layer and rusty scale on surface
The all angles of wheel pair can be handled, make wheel to will not above remain oxide layer and rusty scale.
The technical solution that further limits of the present invention is：
Further, in step c, pellet that ball blast rifle uses includes the first pellet, the second pellet and the 3rd pellet, and described the
The diameter of one pellet is less than 0.67mm, and the diameter of second pellet is more than 0.67mm and less than 2.16mm, the 3rd pellet
Diameter be more than 2.16mm.
The preceding method, the ball blast time is 20-25min in step c.
The preceding method, the pellet cleaning intracavitary include Vacuum sand pump and blowing plant, and the compression is empty
Compressed air from air outlet is blown out and removes pellet and dust of the wheel to upper attachment by device of air, and Vacuum sand pump is used to blow
The pellet and dust fallen siphons away.
The preceding method, in step a, temperature is 45~85 DEG C during degreasing, and concentration of organic solution is 2~6 points in tank liquor,
Temperature is 30~55 DEG C during washing, and drying temperature is 65~110 DEG C.
The preceding method, the pellet that the ball blast rifle uses is the high violent steel wire shot of passivation, and a diameter of 0.3- of pellet
0.5mm。
The beneficial effects of the invention are as follows：
（1）Pellet in the present invention includes the pellet of the first pellet, the second pellet and the 3rd three kinds of different-diameters of pellet, and first
The diameter of pellet is less than 0.67mm, and the diameter of the second pellet is more than 0.67mm and less than 2.16mm, and the diameter of the 3rd pellet is more than
2.16mm, the first pellet since diameter is smaller, to wheel pair impact dynamics with regard to larger, the diameter of the second pellet and the 3rd pellet
It is larger, to wheel pair coverage rate it is larger, therefore can using the first pellet come improve to wheel pair impact force and shorten to wheel
To the impact time, the second pellet and the 3rd pellet can be utilized to ensure coverage rate, while the use of pellet can be reduced
Amount, therefore using the pellet of three kinds of different-diameter sizes, can ensure in the case where improving to taking turns to ball blast efficiency to wheel pair
Shot-blasting quality, by wheel upper remaining oxide layer and rusty scale are removed completely.
（2）Pellet and dust of the pellet cleaning chamber set in the present invention for clean-up wheel to upper adherency, make by throwing
Ball processing wheel to cleaner, wherein, blowing plant be used for blowing out pressurised air, will take turns to upper pellet and dust
Blow off, then Vacuum sand pump is for collecting the dust that blows off and pellet, the surface of wheel pair may finally be made without pellet and
Dust adheres to, and does not interfere with the quality of wheel pair to carrying out in the subsequent processing, in wheel.
Specific embodiment
The present embodiment provides a kind of derusting methods for rail vehicles wheel pair, comprise the following steps：
