Under the occasion that abrasive particles are supplied to a nozzle in a suspension mode, the abrasive can be recovered continuously to be repeatedly used by the cutter. The present invention overcomes the defect that the abrasive can not be continuously recovered and used in the prior art, the matched and used abrasive water jet cutter (No. CN87100891) greatly reduces the trouble of supplementing the abrasive in a device in the prior art, the procedure and the time for processing the used abrasive are saved, and the productivity is improved further.
Description
The present invention relates to containing the Abrasive Water Jet Machining device that spraying water with high pressure of abrasive grain cut sheet metal and so on workpiece, the particularly recovery device of abrasive of this Abrasive Water Jet Machining device.
It is not new coming cutting metal and so on nature with abrasive water-jet, has been used one period.As for material that is used as abrasive material such as quartz sand, cast iron grain, the perhaps powder of diamond dust or corundum.The average-size of this abrasive particle particle from 0.2 to 0.8m/m.
Traditional Abrasive Water Jet Machining operation is such, and promptly water under high pressure and dried abrasive grain are delivered to respectively in the abrasive water-jet nozzle.In nozzle, abrasive grain is sneaked in the pressure flow.The water under high pressure that contains abrasive grain comes out from nozzle with the form of abrasive water-jet, directly contact workpiece.When nozzle and workpiece relatively moved, abrasive water-jet was with regard to cut workpiece.
A shortcoming of this traditional operation is that abrasive grain (it is abrasive material following title) is that the nozzle of doing of delivering to goes, thereby can not reduce size as requiring ground.With this coarse grit (average-size from 0.2 to 0.8m/m) all is unfavorable from multiple reason.At first, they wear and tear the head that touches abrasive material of nozzle and other parts soon.Secondly, the otch that forms on workpiece is too big, common aperture greater than the nozzle head.The another one problem is to produce burr in back of work.Therefore, the Abrasive Water Jet Machining action need machining subsequently that has earlier guarantees precision and fineness.Main shortcoming is that abrasive material can not be retrieved to recycle in a continuous manner.
Related application CN of the present invention has overcome three above-mentioned problems that conventional art is run into for No. 87100891, because used the size more much smaller than existing grit size.
And in order to solve the 4th above-mentioned problem, the retracting device that the purpose of this invention is to provide a kind of Abrasive Water Jet Machining device, this retracting device can not only reach to the cutting after abrasive water-jet energy dissipating effect but also can make abrasive material recycling use in a continuous manner.
Recovery device of abrasive according to Abrasive Water Jet Machining device of the present invention includes:
A returnable, this container are configured to facing to the abrasive water-jet injection assembly, and the abrasive material water that has an import that is used to accept abrasive water-jet and at least one to be used to discharge to accept to come in and the outlet of abrasive material;
A plurality of absorbing balls made from stiff materials that are contained in the described returnable are to absorb the energy of abrasive water-jet;
Described returnable have one to small part be circular inner surface so that make the absorbing ball because the energy of abrasive water-jet and in described container, recycling;
Be used for flexibly supporting the elastic device of returnable;
The cover of a watertight wherein is equipped with described returnable, and an import is arranged on this cover, and the abrasive water-jet that enters described returnable also has an outlet by this import, and this outlet is connected with described abrasive suspension feedway;
Telescopic extends between the import of the import of watertight cover and returnable.
According to characteristics of the present invention, the abrasive water-jet that comes out from related application CN87100891 of the present invention number nozzle is imported into retracting device after cut workpiece.The water that at least a portion reclaims and abrasive particle gets back to the abrasive suspension feeding mechanism so that the reuse abrasive particle.
Be stressed that since according to related application CN87100891 of the present invention number disclosed, abrasive particle is that the form with suspension is supplied to nozzle, so this constant recirculation of abrasive material is attainable.If abrasive particle is the supply nozzle of doing, just this recirculation can not be arranged as prior art.Experiment showed, abrasive particle seldom can be behind cutting operation varying sized and shape, so the effect of cutter sweep be not subjected to abrasive particle recirculation influence and degenerate.The saving grace of this recirculation is not only because it has eliminated processing to the particle of use, and the while has significantly reduced the operating costs of installing.
Another characteristics of the present invention are the structure of retracting device, it must be subjected to the energy of the abrasive water-jet that live in to come.In the past, in order to absorb the energy of water jet,, must immovably be contained in the open containers an of the top with glass fibre or tungsten carbide board or ceramic material no matter be abrasive water-jet or do not have abrasive water-jet.This energy of water jet that is used for the cutting metal workpiece often makes fixing shock-absorbing means damage in several hours, needs to change often.
Therefore, multilayer rigidity absorbing ball is used in the present invention's suggestion in facing toward the returnable of abrasive water-jet nozzle.The inner surface of returnable to small part is circular so that the absorbing ball recycles under the energy of the abrasive water-jet of coming in.Preferably, the material of absorbing ball and abrasive particle is identical.
All absorbing balls constantly recycle in returnable, are exposed to abrasive water jet one by one and flow down weakening its energy, and wear and tear gradually with same speed.This recirculation absorbing ball can absorb the power of abrasive water-jet for more time than traditional fixedly shock-absorbing means.In addition, owing to only need the absorbing ball of relative small number just can use considerable time, the appearance and size of returnable and auxiliary equipment thereof is littler than prior art device.
Above-mentioned and other characteristics and advantage of the present invention, and to the present invention itself, by the accompanying drawing and the explanation of the following demonstration preferred embodiment of the invention, and claim, will more clearly understand.

Fig. 8 is the view similar in appearance to Fig. 3, shows more another remodeling of returnable device.
Now the present invention is explained.
In Fig. 1, across workpiece W, what face toward nozzle 12 placements is a returnable device 26, and the abrasive water-jet J that cut workpiece W with acceptance reclaims the abrasive particle of using.Here the returnable device 26 of Xian Shiing is a simple breaker, and there is an opening at its top to accept abrasive water-jet J.Though this structure is suitable for reclaiming abrasive particle, several improved structures also will be disclosed subsequently.Pipe 28 with pump 30 connects the returnable device 26 that has concentration control container 32, makes the abrasive material and the water recirculation of recovery.
The remodeling 10a of Abrasive Water Jet Machining device shown in Figure 2 and device 10 dissimilarities shown in Figure 1 mainly are abrasive suspension feeding mechanism 22a.Improved abrasive suspension feeding mechanism 22a has a precipitation vessel 54, and it places between returnable device 26 and the concentration control container 32.Pipe 28 is connected on the top of precipitation vessel 54 so that derive the abrasive particle and the water of recovery wherein.Overflow pipe 56 keeps the liquid level in the precipitation vessel 54 constant.
In precipitation vessel 54, have two or more dividing plates 58 to extend downwards, and other two or more dividing plates 60 extend upward from the bottom with the spacing that is parallel to each other from the top with the spacing that is parallel to each other.These two groups of dividing plates 58 and 60 layouts in interleaved relation with each other form a circuitous channel to the liquid that comes from returnable device 26 pumps.When liquid is flowed through this circuitous channel, have only and reclaim the bottom that the big abrasive particle that is suitable for reuse of size in the abrasive particle just can be deposited to precipitation vessel 54.The abrasive particle that is unsuitable for reuse that size is little (that is, under the situation of using corundum less than 3 μ) will be discharged by overflow pipe 56 with a part of recycle-water.
Confirmedly be, the change of size and dimension seldom takes place in used abrasive particle, thereby for reusing without a doubt.Not only because be the economy that material uses, also be that it is easy to dispose the material of using than prior art for the needs of the recirculation of abrasive particle.Another advantage of the inventive method is to be easy to prepare the abrasive suspension of desired concn and it is supplied with nozzle.It is this that abrasive particle stably is supplied to nozzle is the key that produces constant width otch.
As said mistake, traditional fixedly shock-absorbing means is glass fibre and tungsten carbide or ceramic wafer for example, and it is not all right being used for to the energy that is subjected to abrasive water-jet because their very its result of quick-wearing just need often to change.This shock-absorbing means must be along the paths arrangement of nozzle, and the area of its layout is more much bigger than the part that water jet hits.Therefore, traditional shock-absorbing means is subjected to very fast concentrated wear inevitably, thereby needs often to change.
Can consider to increase the thickness of this shock-absorbing means, perhaps this shock-absorbing means is placed in the open-topped container of having annotated water, so that prolong their service life.These solutions are unaccommodated, because can increase the whole recovery device size inevitably.The device of this heaviness is not suitable for computerization or autoamtic cutter especially, because all be to be transported along decide the cutting route walking with respect to giving of workpiece at these occasion abrasive water-jet nozzles and retracting device.When particularly having adopted the container of dress water, abrasive water-jet must be aligned the surface perpendicular to water; In other words, the abrasive water-jet nozzle can only be used for downward scope.The flexibility of cutter sweep has been dwindled in this restriction significantly.
Therefore the present invention proposes several improvement returnable apparatus structures, and they have all broken away from the inconvenience of said fixing shock-absorbing means.
First kind of form of returnable device
As shown in Figure 3, the returnable device 26a of first kind of form comprises the shield cap 200 of a watertight, and it has an import 202 and an outlet 204.Import 202 is used for accepting the abrasive water-jet J from abrasive material nozzle 12,12a or 12b of cut workpiece W at the top of cover 200.Be positioned at outlet 204, connect abrasive suspension feeding mechanism (22a among 22 among Fig. 1 or Fig. 2) near cover 200 bottoms.
In the cover 200 returnable 206 is arranged, the seat 210 that it is made by a tungsten carbide or similar material flexibly is supported in one and can be subjected on the heavily loaded helical compression spring 208.The returnable 206 here is spherical, and it has an import 212 in order to accept abrasive water-jet.A plurality of outlets 214 are made into and spread on the returnable 206, in order to discharge water and the abrasive material of accepting.Telescopic 216 is connected between the opening 212 of cover 200 opening 202 and returnable 206, so that returnable is made elastic displacement with respect to cover.
A plurality of absorbing balls 218 are placed in the returnable 206.Preferably, the same material (that is, pottery) of the abrasive particle that contains among the absorbing ball 218 usefulness abrasive water-jet J is made, though the material of steel or similar hard wear resistant also can adopt.
The effect of returnable device 26a is the energy that absorbs the abrasive water-jet J that enters constantly.To force some absorbing ball 218 to head on the bottom of the spherical inside surface of returnable by covering abrasive water-jet that 200 import 202 and telescopic 216 enter returnable 206, shown in arrow among Figure 13.The downward thrust that also with arrow this some absorbing ball is shown in figure will cause other absorbing balls to climb up the rounded internal surface of returnable 206, and arriving is the below of returnable import 212 just, and the abrasive water-jet of being come in again pushes one by one.The absorbing ball 218 of doing this recirculation in returnable 206 rotates around the axis of oneself separately.
Therefore, the energy of abrasive water-jet J will be converted to the energy of the recirculation and the rotation of absorbing ball 218.This kinetic energy of absorbing ball will because of between the absorbing ball and absorbing ball and returnable 206 between fricative heat dissipated.Effective dissipation of this water jet energy has reduced the impact of abrasive water-jet to the absorbing ball of direct exposure under it.Absorbing ball in returnable 206 will wear and tear very slowly, and the more important thing is, with same speed wearing and tearing.The service life of recirculation absorbing ball is more much longer than traditional fixedly shock-absorbing means.
What also should propose is that in the present embodiment, returnable 206 is contained on the stage clip 208.Support that like this when abrasive water-jet J dropped on the absorbing ball 218 in the returnable, returnable 206 not only can be made elastic displacement up and down, also can do the lateral elasticity displacement, but its scope will be subjected to the restriction of telescopic 216.The energy of abrasive water-jet J will also be dissipated by spring 208 not only by the absorbing ball 218 of recirculation.Can understand that thus returnable device 26a has longer service life than the fixedly shock-absorbing means of prior art.
The water that contains abrasive particle is just flowed out by the outlet 214 of returnable 206 after dropping on the absorbing ball 218, concentrates on the bottom of cover 200, shown in 220.The liquid 220 of this recovery is delivered to abrasive suspension feeding mechanism 22 or 22a by pump 30 on demand, as depicted in figs. 1 and 2.
One of advantage of returnable device 26a is owing to one by one bear the power of abrasive water-jet J, only to need the absorbing ball of relative small number just can use a very long time.Like this, returnable 206 just can be made small size, and whole recovery case 26a is also just little.
When absorbing ball 218 was used identical materials with the abrasive particle that cuts, an additional advantage had just shown.When abrasive water-jet J drops on the absorbing ball or when the absorbing ball clashed into mutually, the absorbing club of making of abrasive particulate material oneself produced abrasive particle.This abrasive particle does not need to separate from reclaim liquid 220, but allows it and then to reclaim liquid flow through together abrasive particle feeding mechanism 22 or 22a, can not damage the cutting power of abrasive water-jet J.
After 218 wearing and tearing of absorbing ball, need to change.The absorbing ball of changing wearing and tearing is easy to, so that the size of returnable 206 can be done is little.Returnable 206 can be taken out from covering 200, and it is turned around, has just poured out with the absorbing ball of crossing, and will go into new absorbing ball again.
Second kind of form of returnable device
It is spherical that the returnable that contains the absorbing ball needs not be, and for example can be columnar, and this returnable device 26b with second kind of form in Fig. 4 and Fig. 5 illustrates.The returnable 230 of tubular is installed on the spring base 210 in the cover 200 by horizontal positioned, and a pair of lug 232 of returnable 230 is rotatably held on by a pair of fixed mount 234 on the seat 210.Yet, the angle that the rotation of returnable 230 is limited in stipulating, this can adopt any suitable device, because this device is common, no longer illustrates.
When on the normal angled position of returnable at it, the import 236 of returnable 230 is at the axis alignment of the vertical direction and the returnable of getting along well, as shown in Figure 4 and Figure 5, but one side of the position of deflection and returnable axis alignment.Telescopic 216 is in this import of returnable 230 and covers between 200 the import 202.Other CONSTRUCTED SPECIFICATIONs of returnable device 26b can be identical with the returnable device 26a among Fig. 3.
Like this, because the biasing of the import 236 on the cylindrical shape returnable 230, abrasive water-jet J will make the axis revolution of some absorbing ball 218 around returnable, shown in arrow among Fig. 4.In addition, because import 236 is placed in the mid point of returnable 230 length dimensions, as shown in Figure 5, absorbing ball 218 will be urged downward two axial ends of returnable separately.The absorbing ball of recirculation will be exposed under the abrasive water-jet J seriatim.Simultaneously, abrasive water-jet J will make the axis vibration of returnable 230 around it, in addition, make stage clip 208 deviations, thereby make returnable produce displacement.This vibration of returnable self and displacement are cooperating the recirculation of the absorbing ball 218 in the container, the energy of the abrasive water-jet J that dissipated.
The third form of returnable device
Fig. 6 has shown the returnable device 26c of the third preferential form of implementation, and what it was different with returnable device 26a among Fig. 3 is that a pendulum spring device 240 is arranged, to replace stage clip 208.Pendulum spring device 240 is contained on the cover 200, is flexibly supporting returnable 206 to support the strength of the abrasive water-jet J that is come in.Other CONSTRUCTED SPECIFICATIONs of this returnable device 26c can be the same with returnable device 26a.Its operation also is similar to returnable device 26a, and the effect of its pendulum spring device 240 is identical with stage clip 208.
The 4th kind of form of returnable device
The returnable device 26a of the preferential form of implementation of saying above, the returnable 206 among 26b and the 26c and 230 can both be modified into the returnable 250 shown in Fig. 7.The returnable of having improved 250 has only an outlet 252 that is arranged in the top, is distributed in outlet of container partially with what replaced above-mentioned returnable device.Outlet 252 this arrangement causes that the collection in container 250 reaches such level to withdrawal liquid, and promptly absorbing ball 218 all is submerged in the liquid, thereby their recirculation in container one will be more steady.
The 5th kind of form of returnable device
Referring to Fig. 8, wherein shown the returnable device 26d of another kind of preferential form of implementation, be characterized in that returnable 260 is to make spiral type with metal pipe.The recirculation of the absorbing ball 218 that filling is quickened in design, and returnable 260 comprises a straight line portion 262 and a curved portion 264.
The straight line portion 262 of returnable 260 vertically extends, or along the extension path of the abrasive water-jet J that comes out from nozzle 12, the top has an import 266 to allow abrasive water-jet come in.Curved portion 264 can be imagined the bottom of straight line portion 262 is connected the centre of returning to arrive two-end-point on the straight line portion.Curved portion 264 is arc basically, and straight line portion 262 extends along the tangent line of the arc of curved portion.A plurality of outlet openings 268 are lined up array on the whole surface of returnable 260.
Returnable 260 is placed on the rigid holder 270 with tungsten carbide or similar material system in the shield cap 272 of watertight.Covering has a water jet import 276 on 272 tops 274, its diameter is more bigger than abrasive water-jet J.There is an expansion section 278 bottom of water jet import 276 or the inner, are used for closely accommodating the entrance point part of returnable, therefore, this container on the certain position that is held in the cover 272.Cover 272 is near the place, bottom an outlet 280 being arranged, so that withdrawal liquid is pumped to abrasive suspension feeding mechanism 22 or 22a.
The size of absorbing ball 218 and number are decisions like this in the returnable 260, and they can be recycled in container as following will saying.In the form of all above-mentioned returnable devices, absorbing ball 218 preferably and the used abrasive particle of Abrasive Water Jet Machining make with identical materials.
In this spiral type returnable 260, absorbing ball 218 constantly recycles by annular basically path, shown in arrow among Fig. 8, and the energy of the abrasive water-jet J that comes in to dissipate.Be that proper explanations is how to produce recirculation about absorbing ball in returnable 260 below.
When superfine abrasive water-jet J enters the returnable 260 from nozzle 12, and when hitting those and being in container import 266 central authorities or near absorbing ball 218, these balls will be forced to downwards.These balls will impel some other sphere diameter to outwards to bottom offset, thereby will make more other absorbing ball climb up the inner surface of returnable 260, then since they self weight fall to the cross section of the pipe of making returnable central authorities.Like this, absorbing ball 218 constantly carries out the displacement of this axial symmetry in the straight line portion 262 of returnable 260.
Because this local displacement of absorbing ball is near container import 266, these are housed in ball in the curved portion 264 of returnable 260 and will be one by one fall into straight line portion 262 from its port of export 282.Therefore, the ball in straight line portion 262 will move down gradually, enter and climb up curved portion 264 subsequently, finally go into straight line portion 282 times from the port of export of curved portion.
Like this, in the preferential form of implementation of all above-mentioned returnable devices, all absorbing balls 218 in returnable 260 will be exposed under the impact of the abrasive water-jet J that comes in the container import 266 near seriatim, so wearing and tearing at the same rate.Because without any concentrated wear, the absorbing ball of recirculation will obtain than the much longer service life of fixedly shock-absorbing means that has earlier.
The common advantage of all preferential form of implementation of returnable disclosed herein is a compact conformation, and in fact they only come to the energy that is subjected to abrasive water-jet with a bit.For example last disclosed returnable device 26d may diminish to has only the 150M/M height.Therefore, in the cut workpiece device that the sort of nozzle moves with respect to fixation workpiece, the returnable device can move along cutting route together with nozzle.
What also can understand is that the state that returnable device of the present invention does not need to keep up is accepted abrasive water-jet.Nozzle and returnable device all can be contained on the position control, and like this, nozzle utilization ejection abrasive water-jet comes cut workpiece to be not only vertically downward, also can be in any other direction.
