Abstract
The utility model relates to a penetration and casting-on machine for cast belonging to the technical field of industry. When the existing penetration and casting-on machine works, the continue vacuum pumping can not be realized during the course that the leakage repairing liquid enters the leakage repairing cylinder, and thus, the space of the leakage repairing cylinder is gradually reduced, while the vacuum degree is also gradually reduced, and as a result, the leakage repairing liquid is not easy to permeate the cast. The penetration and casting-on machine for cast of the utility model arranges a contact at the lower part of the vacuum pumping pipeline of the leakage repairing cylinder. When the leakage repairing liquid reaches the contact position, the contact can send out a signal to close the valve where the leakage repairing liquid enters. The continue vacuum pumping can be realized during the course that the leakage repairing liquid is poured to keep the vacuum state of the leakage repairing cylinder at a high level to enhance the effect of repairing the cast.
Description
The present invention is industrial used foundry goods infiltration leakage patching machine.
The various foundry goods that bear sealing requirements such as pneumatic-hydraulic because casting flaws such as pore, loose, shrinkage porosite, trickle needle-like slit make its sealing not reach the properties of product requirement, thereby cause a large amount of waste products.Infiltration mending-leakage technology can remedy that those naked eyes are invisible will make the foundry goods that seal tightness test could be found seepage.Now the craft leakage mending method of existing leakage patching machine is as follows: put into the mending-leakage cylinder after will having the foundry goods of seepage defect to clean, vacuumize in cylinder, extracted air, moisture content and ionized impurity in the foundry goods slit simultaneously.Stop pumping vacuum then, the perfusion leakage-repairing liquor utilizes vacuum and capillary theory in the mending-leakage cylinder, and leakage-repairing liquor is seeped in the slit of foundry goods by suction.Then to applying 2～6 atmospheric pressure in the mending-leakage cylinder, make leakage-repairing liquor further penetrate into the slit of foundry goods under pressure, after solidifying, promptly reach the purpose of foundry goods mending-leakage again.From said process as can be seen, it is should be in the high vacuum state in the foundry goods slit in the mending-leakage cylinder when leakage-repairing liquor infiltrates into the foundry goods slit that the mending-leakage effect of leakage patching machine, key are.But existing leakage patching machine but has following shortcoming: after the equipment that is extracted in the mending-leakage cylinder may reach maximum vacuum, and the stop pumping vacuum, leakage-repairing liquor flows in the mending-leakage cylinder; Along with leakage-repairing liquor enters in the mending-leakage cylinder, the space dwindles gradually in the mending-leakage cylinder, and atmospheric molecular concentration increases relatively, and vacuum just descends gradually in the mending-leakage cylinder, at last up near atmospheric pressure.This process can be illustrated by Fig. 1.Fig. 1 reaches stop pumping vacuum after the maximum vacuum for having taken out in the mending-leakage cylinder, in entering the leakage-repairing liquor process, and the coordinate diagram of leakage-repairing liquor liquid level and vacuum variation, X-axis is represented vacuum, and Y-axis is represented the leakage-repairing liquor liquid level, and H represents the height in mending-leakage cylinder space.Obviously, leakage-repairing liquor enters in the mending-leakage cylinder, and vacuum descends, and the gas molecule quantity in the foundry goods slit increases, and has hindered leakage-repairing liquor and has infiltrated in the foundry goods slit, has reduced the mending-leakage effect of leakage patching machine.Use existing leakage patching machine unsuccessful, also need three mending-leakages of secondary mending-leakage etc. a mending-leakage of some foundry goods.Because the above-mentioned shortcoming of leakage patching machine influences.And existing leakage patching machine can not vacuumize in leakage-repairing liquor enters the process of mending-leakage cylinder when operation simultaneously, and if not leakage-repairing liquor just may be extracted into vacuum pipe to vavuum pump.The leakage patching machine that " machine-building " magazine the 4th phase of nineteen eighty-three 21～23 pages of leakage patching machines of being reported promptly belong to this type Chongqing automobile fitting factory imported France also belongs to this type.
The objective of the invention is: overcome above-mentioned shortcoming, provide a kind of improved foundry goods infiltration to leak the leakage machine, it not only can guarantee to enter at leakage-repairing liquor, and the space in the mending-leakage cylinder all is in the high vacuum state in the overall process of mending-leakage cylinder, and the phenomenon that leakage-repairing liquor enters vacuum lead can not take place.
Invention is achieved in that a pipeline that connects vacuum source on mending-leakage cylinder top, below this pipeline, best position is that the contact that can send control signal is set in the place of 5～300mm, this contact links to each other with leakage-repairing liquor liquid flowing valve controlling organization, when the leakage-repairing liquor liquid level contacts with the contact, a signal is sent in the contact, by controlling organization leakage-repairing liquor feed liquor valve cuts out.Adopt foundry goods of the present invention infiltration leakage patching machine mending-leakage foundry goods, in being extracted into the overall process that maximum vacuum entering leakage-repairing liquor in the mending-leakage cylinder, all do not turn-off vavuum pump.Suitably select the bore and the vavuum pump capacity of leakage-repairing liquor feed liquor valve, can make leakage-repairing liquor enter that the space in the mending-leakage cylinder all is in the high vacuum state in the overall process of mending-leakage cylinder, when the leakage-repairing liquor liquid level contacts with aforementioned contact, the signal that send the contact is closed the feed liquor valve by controlling organization, guarantees that leakage-repairing liquor can not enter in the vacuum lead.This process can illustrate by Fig. 2.Fig. 2 reaches maximum vacuum (continue to vacuumize this moment) for taking out in the mending-leakage cylinder, enters in the leakage-repairing liquor process, and the coordinate diagram that leakage-repairing liquor liquid level and vacuum change, X-axis is represented vacuum, and the y axle is represented the leakage-repairing liquor liquid level, and H represents the height in mending-leakage cylinder space.Obviously, leakage-repairing liquor enters in the overall process of mending-leakage cylinder and still keeps the high vacuum state, the gas molecule quantity in the foundry goods slit still seldom, this just helps leakage-repairing liquor and permeates in the foundry goods slit, has strengthened the mending-leakage effect of leakage patching machine greatly.
The present invention is because only need to set up the mechanism of a contact and control feed liquor valve, so structure is simple especially on original equipment.The mechanism of contact and control feed liquor valve can adopt prior art, such as electric control or mechanical control.
