Description

Vibrotumbling machine

Technical field

The present invention relates to a kind of Vibrotumbling machine, particularly relate to a kind of Vibrotumbling machine of handling goods that is applicable to at least one cavity or inner surface.

Background technology

Under the situation about particularly obtaining through galvanic corrosion technology at least one surface, Vibrotumbling technology has been represented a kind of solution that is used to remove the economy of superficial layer.

Superficial layer is actually through galvanic corrosion and obtains, and wherein said superficial layer is hard and crisp substantially, perhaps under any circumstance for example have the microstructure and the morphological feature of not allowing for the application of particular type.

An instance of such goods particularly comprises the object with at least one cavity such as rotor.

It is simple and economical handling through the Vibrotumbling outer surface, and this is because the goods that will handle are immersed in the abrasive mixture.

Goods are maintained in the container, said container and then receive the effect of vibrating device and produce vibration.

It is not hard especially material composition, abrasive grain, water and additive for the common of " medium " that abrasive mixture generally comprises multiple known english term.

Various material compositions, i.e. medium, function be to transmit kinetic energy to abrasive grain so that these material compositions bump against on the goods that will handle.

The abrasive grain that each medium composition is present in the abrasive mixture surrounds, and receives the vibration from vibrating device through said container.

In this manner, the various compositions in the abrasive mixture bump against on the outer surface of the goods that will handle, cause the abrasive grain said same surface that rubs.

Through the said surface that rubs, said particle causes the removal of material on the outer surface of goods, thereby the wearing and tearing and the material that produce superficial layer are from wherein removal.

Therefore, oscillating movement is endowed and is used for Vibrotumbling in the market or vibrates accurately machined abrasive mixture machine, and this oscillating movement is delivered to the goods that will handle or the surface of equating thereafter.

In other words, vibration is delivered to the goods that will handle through abrasive mixture, and wherein said goods are immersed in the abrasive mixture fully; Said abrasive mixture is maintained in the container that is vibrated.

Said vibration and then be delivered to abrasive mixture, and therefore be delivered to said goods.

The vibration that causes abrasive mixture through vibrating device produces the relative motion of abrasive mixture with respect to the product surface that will handle exclusively.

Therefore a shortcoming of current machine is: because said abrasive mixture does not flow in said internal cavities; Therefore cause producing so-called " embolism " effect, make this relative motion minimizing or complete obiteration in groove, opening, cavity and narrower fin.

Because use existing machine can not realize abrasive mixture and the effective relative motion between the unapproachable pending product inner surface usually, it is impossible therefore said inner surface effectively being handled.

Can cause like this: because through the abrasive action of abrasive mixture said inner surface to be handled is impossible, therefore be necessary usually to obtain product through different processes, common like this have a higher operating cost, also can cause quality to reduce simultaneously.

Even, can not effectively handle inner surface when using vibration during abrader, the inner surface of groove and particularly for example in some rotors, have the inner surface in the thin chamber of narrower section for example.

In this case, friction energy when lapping device arrives said inner surface, perhaps worse situation is to be maintained at said groove or cavity inside.

In both of these case, can not obtain abrasive mixture in the useful effect of passing through on the quite thin and narrow accessible said inner surface of section, wherein the scope of section minimum of a value is the 5-10 millimeter.

Another shortcoming is: under any circumstance, for wideer section, mainly at the place, outside near the product that will handle, said surface receives uneven grinding.

This is because the change of direction and speed causes frequency and the impact strength of higher abrasive mixture composition on object.
