Abstract
The present invention relates to a kind of complicated cavity and oil circuit casting inner wall cleaning method, continuously poured into casting cavity and oil circuit from one end by steel ball, flowed out from one end, equipment drives casting vibration at the same time, steel ball is just as countless hand hammers, casting cavity and oil circuit inner wall are tapped, so that the fifth wheel such as residual sand being adhered in cast inner wall departs from casting, complete cast inner wall cleaning.The present invention utilizes steel ball in casting cavity and oil circuit in flow process, and the impact force produced with cast(ing) surface, clears up casting cavity and the sand grains and burr of the attachment of oil circuit inner surface, lift casting inner surface quality.
Description
Technical field
The present invention relates to a kind of cast inner wall method for cleaning, especially a kind of complicated cavity and oil circuit casting inner wall cleaning side
Method.
Background technology
At present, clearing up scab and the method for burr mainly has：
1) shake-out, the sand grains and burr of cast(ing) surface attachment are removed using vibration of the casting on shakeout；
2) water explosition blast cleaning, casting utilize the shrinking percentage difference and coolant between sand grains and casting body in quick cooling procedure
To the impact force of cast(ing) surface, sand grains and burr that cast(ing) surface adheres to are removed；
3) blast (shot-peening), removes the impact force of cast(ing) surface using the sand grains (abrasive material) of high speed the sand grains of cast(ing) surface attachment
And burr；
4) highly pressurised liquid is cleared up, and using water or other liquid, the flowing cleaning cast(ing) surface of the high speed in core cavity or oil circuit is attached
The sand grains and burr, are cleared up sometimes according to the increase abrasive material in liquid is needed；
5) gases at high pressure are cleared up, the pressure differential produced using gases at high pressure in core cavity or oil circuit during flow at high speed,
Clear up the sand grains and burr of cast(ing) surface attachment；
6) chemical cleaning, is reacted using chemical reagent and sand grains, the sand grains of cleaning cast(ing) surface attachment.
Above method is not thorough there is scab and burr cleaning, surface quality of continuous castings is without substantially carrying
The problems such as rising, or causing casting deformation, corrosion, can not meet the cleaning requirement of complicated cavity and oil circuit casting inner surface.
The content of the invention
The object of the present invention is to provide a kind of complicated cavity and oil circuit casting inner wall cleaning method, can effectively remove attached
The scab on casting inner surface and local sharp side, lifts casting cavity and oil circuit inside surface roughness.
The concrete technical scheme of the present invention is that the complicated cavity and oil circuit casting inner wall cleaning method include following step
Suddenly：
(1) casting for clearance, that there is complicated cavity and oil circuit is prepared；
(2) design and make fixture, casting can be fixed on the workbench of steel ball flow device by the fixture, and pacify casting
Generation is not contacted after dress with other any parts to collide with；
(3) casting is installed on fixture, is then installed on by fixture on steel ball flow device, and steel ball in equipment goes out
Mouth is located at the top position of casting, opens outlet, steel ball is injected into inside casting cavity and oil circuit, until casting cavity and oil
Steel ball is full of in road and has steel ball to be flowed out from casting bottom, a diameter of the casting oil circuit or cavity minimum diameter of the steel ball
1/3；
(4) steel ball flow device parameter is selected：Frequency is 50-60Hz, and amplitude 3-4mm, the casting vibrations time is 2-2.5h, then
Start steel ball flow device；
(5) by the steel ball port closing of steel ball flow device, the frequency modification by steel ball flow device is 1-2Hz, amplitude 2-4mm,
The casting vibrations time is 0.5-1.0h, so as to steel ball in casting cavity and oil circuit be removed clean；
(6) casting, and final inspection are pulled down.
The present invention is continuously poured into casting cavity and oil circuit by steel ball from one end, is flowed out from one end, while equipment drives
Casting vibrates, and steel ball taps casting cavity and oil circuit inner wall just as countless hand hammers, so that being adhered in casting
The fifth wheels such as the residual sand on wall depart from casting, complete cast inner wall cleaning.In vibration processes, steel ball can be to casting inner surface
Protruding parts produces impact, polishing, plays the role of light decorations, makes cast(ing) surface smooth.In view of steel ball in oil circuit free flow
It is dynamic, the 1/3 of diameter of the steel ball selected as casting oil circuit or cavity minimum diameter, the parameter such as amplitude, frequency ensures that steel ball can be gone
Scab and burr, and be unlikely to destroy casting.After employing the vibration of steel ball stream, the sand grains of casting cavity and the attachment of oil circuit inner surface
Removed with burr, surface quality of continuous castings is promoted to C50 by original C90.The present invention is using steel ball in casting cavity
In flow process in oil circuit, the impact force with cast(ing) surface generation, clears up casting cavity and the sand grains of oil circuit inner surface attachment
And burr, lift casting inner surface quality.
