Description
Technical field:
The present invention relates to aerial blade and complex components to clear up applied technical field, specifically provide a kind of aerial blade and
Complex component shell pressure-vaccum one cleaning plant and method for cleaning.
Background technique:
In the prior art, because investment shell intracavity cleaning it is not clean caused by nonmetal inclusion account for aerial blade and complex structural member casting
The 30%-60% of the total loss due to spoiled work of part is technical problem urgently to be solved.
The substances such as the floating ash of aerial blade and complex structural member investment shell intracavity, the overlap to fall off are to cause the nonmetallic folder of casting
The main reason for miscellaneous defect.Aerial blade and complex structural member because there are type core or itself structure is complicated, corresponding investment shell intracavity
Structure is more complicated, and the current country generallys use the cleaning aerial blade such as clear water or alcohol and complex structural member investment shell intracavity,
Because shell is semi-closed structure, clear water or alcohol etc. can only unidirectionally inject, and flow velocity is very slow, and biggish sand grains etc. is miscellaneous in shell
Object is not easy to wash out, meanwhile, clear water or alcohol etc. must first be injected and be flowed out again, blade shell or complex thin-wall knot containing type core
The investment shell intracavity circuit of structure is complicated, there are narrow zone, and liquid injection easily leads to the sundries such as overlap, sand grains, and to pour investment shell intracavity narrow
Narrow place and be jammed, sundries is difficult to clean up.Clear water or alcohol etc. can soak shell and shell inner mold core simultaneously, and shell needs
Reheating is wanted to dry, cumbersome, production efficiency is low.In addition, clearing up the shell of core pattern containing type using liquid such as clear water or alcohol
When, the moisture contained in liquid may form the crystallization water with ingredients certain in shell loose core, in shell casting process, knot
Brilliant elutriation goes out, and causes the metallurgical imperfections such as casting pit.
Realize the objects such as the floating ash for fast and efficiently clearing up aerial blade and complex structural member investment shell intracavity, the overlap to fall off
Matter is of great significance.Accordingly, it is desirable to obtain a kind of aerial blade that technical effect is excellent and complex component shell with blowing
