Description
Technical field
The present invention relates to the method and apparatus that compacting material is used, or rather, the present invention relates to the vibration of in modeling process " wet feed ", be used to produce moulded body,, especially produce electrode in the aluminium electrolytic industry and use so that in fusing industry.
Background technology
Kind electrode, especially anode is to stand compacting and produce in a vibrating device by " wet feed ", and it can comprise a moulded suitcase, has a base plate and sidewall to be installed on the table top, increase a plummet, it allows between mould walls (sidewall of moulded suitcase) to lower slider.Here mainly contain two types vibratory equipment be used for the mold pressing anode can be from market supply; Have the plummet vibratory equipment and have table vibration equipment.Main difference between them is the position that equipment is produced the resonator device of dynamic vertical input power.For having the plummet vibratory equipment, resonator device be fixing/be integrated in the plummet.For having table vibration equipment, resonator device be fixing/be integrated in the table top.
Patent NO Patent no.132359 relates to the vibratory equipment that has the plummet vibration, is used for the compacting moulded body, so that produce anode and cathode block.Specification points out that the plummet vibration has the simplification that many advantages surpass table vibration, especially relevant devices.Hammer into shape by mobile resonator device to aluminium, it is said that vibration principle can simplify,, be fixed on the ground because base plate should be static.In accordance with the reference, compression is that base plate is static, and mould walls is fixed to base plate in vibrative process by only being arranged on lid counterweight or the plummet that one or more vibration machines reach.Described in accordance with the reference solution, table top are static base plates, and with the mechanical system of avoiding being connected with several vibrating objects, they also are shown in the accompanying drawing of this list of references.
JP-A-11226698 discloses one and has gone up the vibration pressure setting, is positioned at the vibrating stamping press that a greensand mo(u)lding is used.The principle of vibration is similar to the above list of references, and is different with principle of the present invention.
Patent NO 132359 described mechanical systems in experiment through overtesting, but experimental result shows that the vibratory equipment with a vibrating object can not produce expected result.Its reason is that dynamic energy extends to environment and equipment is also unstable.Table top has carried out improving and converting to an object in experiment subsequently, and it can be by placing a spring k
1With a damper d
1At table top m
bAnd between the base plate U and vibrate, see Fig. 1.In this figure, anode mass m
aBe to illustrate with a complex spring, it also can comprise a spring and a damping element k
2, d
2Be that anode mass or spring-damper system between table top and ground are compressed as complex spring easily, because complex spring has a real spring element and a magnetic hysteresis damping element.Anode mass can certainly have other damping form that is different from the magnetic hysteresis damping, such as frictional damping etc.In an identical manner, multi-form damping can be created in the real damping element, such as the rubber cushion assembly that is installed between table top and the base plate.In Fig. 1, the vibration plummet is as m
1Illustrate.Dynamic input power F facing to equipment
Dyn-inBe a vertical cycle power.According to above-mentioned adjusting, improved equipment will comprise the coupling mechanical system that has two vibrating objects.A matching system that has two vibrating bodies also can be vibrated to table top rather than sets up to plummet by applying.
Above-mentioned improved result is that the noise to environment reduces significantly.Many reasons are arranged here, wherein:
Use two vibrating objects and by selecting a frequency range, table top and plummet be with effectively opposed (to 180 °) vibration therein, increases facing to the dynamic gain of the compression stress of anode mass, because table top also is accelerated and acts on compression stress.This some meaning can reduce facing to the dynamic input power of equipment, to reach the identical dynamic compression facing to anode mass.In turn, it causes reducing facing to the dynamic conveying capacity of base plate U, because dynamically input power reduces.
At table top m
bAnd the damper d between the base plate U
1Consumed dynamic energy.
Base plate U has been protected from being the impact of plummet A.An impact comprises a scope of frequency component.If energy is directly from plummet, may be very high and out of order to the dynamic energy of landing ground.Table top plays a protective effect, thereby makes ground stand to have and a dynamic continuous sinusoidal force of input power same frequency component from table top, rather than from the impact of plummet.
Equipment is because damping element d
1And stablize.The low frequency erratic fluctuations of equipment is damped.
In conjunction with development, determine that according to above-mentioned knowledge equipment should not comprise a base plate or basis (below the equipment in a large number by animal body) according to equipment of the present invention.Have been found that rational equipment should isolate the dynamic energy of itself as much as possible, it is absorbed in the equipment, and is being compacted as much as possible/object of mold pressing in, thereby make it be transmitted into environment with minimum amount.In improved equipment, vibratory equipment can be parked on a underground basis, and it has independent task is the remaining dynamic energy of damping by the vibratory equipment emission.
Also suggestion for example applies a constant compression force to plummet with a hydraulic actuator (figure number 16 among the figure) in above-mentioned patent NO 132359.Its weight that is intended that the minimizing plummet.This is to apply outer static force to very disadvantageous mode of plummet.At first, hydraulic actuator is to be connected to base plate with fixed form.Dynamic energy subsequently will be by the connector expansion to base plate.Secondly, hydraulic actuator has damping and will directly consume the dynamic energy of having a mind to be used for anode mass.Dynamic gain to the anode object reduces.Once used the experiment of a hydraulic actuator, but failed for the above reasons.
Summary of the invention
The present invention relates to further improvement of existing technologies, a kind of method and apparatus that it provides compacting material to use, the especially vibration of " wet feed " in mold process is used to produce moulded body, uses so that produce electrode in fusing industry.Equipment has two model assemblies, and one of them has the vibration that applies thereon in compacting process.And, model assembly, for example table top and plummet are integrated in fact mutually when vibration, at this moment by a static compression force, it comprises at least one spring k
3Vibratory equipment can be designed as a closed system, and the vibrational energy that wherein is emitted to environment is as far as possible little.Four embodiment of equipment are closed systems, and they are shown in Fig. 2-6.Basic difference between the embodiment shown in embodiment shown in Figure 1 and Fig. 2-6 is that the table top in the latter is by one or more spring k
3Or be equivalent to spring k
3A device be connected to plummet.
Though the plummet that respectively illustrates vibrates, principle of the present invention also can by table top be the vibration and realize.Principle of the present invention can also be by the horizontal vibration of model assembly and is used.These model assemblies can be installed as a kind of mode subsequently, make them can slide across a substantially horizontal base plate, for example, by model assembly by a supporting members support, its (not shown) that can on a horizontal direction, slide.
Use the present invention, material can be compacted sooner and more accurately, and has higher compaction and have to the less energy loss of environment, is better than that prior art equipment can accomplish.Fig. 6 also illustrates this equipment and how can mechanically realize, also reaches in such a way with vacuum vibration, and vacuum chamber is as far as possible little and the time of bleeding is very short herein.1-18 limits according to claims, and these and other advantage can use the present invention to reach.

3Object.Plummet must be by having performance and a spring k
3Equivalent equipment is connected to table top.Equivalent spring must be progressive, and the static force by it on this meaning must be and how many quality m
aBe compressed irrelevant.Use k
3It must change static force by table top to plummet, or keep its constant and quality m
aCompression irrelevant.Meanwhile, represent k
3Equipment must have minimal damping because it makes the as a whole dynamic energy of obtaining by equipment.An example of this equipment can be an air pressure adjustable bellows, and as shown in Figure 6, wherein one group of bellows is the every end that is placed on york piece.Quality m when bellows " compresses " plummet near vibration

As an exception, have spring constant k

F
Ayn-in: to the mechanical dynamic input power of vibratory equipment.The cyclic force that has one or more frequency components.Be fixed to the resonator device that plummet is used for plummet vibration and produce this dynamic input power F
Dyn-inHave and compressed quality m
aIdentical direction.In Fig. 6, resonator device is integrated in the york piece.The effect of the parameter of vibrating for plummet during vibration:
k
1: vibratory equipment is to have two oscillating mass, an active mass m
1With a passive mass m
bOne the coupling mechanical system.
Increase facing to quality m
aThe dynamic gain of dynamic force.Facing to quality m
aThe compression stress increase be because quality m
bAlso act on dynamic compression force to a great extent.
Reducing to the noise of environment is because table top and plummet cancel each other out facing to base plate when opposed to a great extent effective.Therefore less facing to the dynamic force of the transmission of base plate.
Advantages of higher stability is because d
1Filter out the interior undesirable low-frequency oscillation of vibratory equipment to table top and plummet, unsettled thereby the equipment that prevents becomes.
The less noise to environment is because d
1Consumed energy and conduct are facing to the function of the damper of base plate.
Yet, facing to quality m
aThe dynamic gain of reduction of dynamic force can produce, if damping is too high or the fundamental frequency of compression stress is too low, thereby make it be in low-frequency range, make d
1Task with damping.
k
3Introducing k
3: use from the static force of table top to plummet.
Facing to quality m
aContinuing to increase the dynamic gain of dynamic force, is according to quality m
aA higher suppressed range and a higher frequency.Because might face toward quality m
aUse k
3Increase static force, facing to quality m
aDynamic force also will increase.Resonator device also is to pass through k
3Be connected to table top indirectly, thereby make it act on the acceleration that increases table top and also increase dynamic force.The other reason of higher dynamic gain is to pass through k
3Static force be directed at quality m
aDynamic fluctuation, near total dynamic fluctuation of table top and plummet.The dynamics of plummet is therefore at compressed quality m
aInterior " being compressed " is lower, and it causes m
aHigher suppressed range.The operating frequency of equipment also increases, because quality m
aQuicken table top and plummet to a great extent, because it contacts longer through an oscillation period with plummet.Higher dynamic force will act on compressed quality m
aThe possibility of higher degree compacting.
The time of vibration that reduces is according to m
aHigher frequency and higher suppressed range.Cause higher ability like this.Measure and show that time of vibration can shorten by about 60S to about 20S.
The noise that reduces is because k
3Stores dynamic is in the inside of equipment and therefore launch less to environment.At k
3The dynamic energy of interior storage is emitted to quality m when vibration
a, k at this moment
3Extend or m
aCompression.Equipment becomes a more system of sealing, if spring k
3Rigidity increase, equipment can be stored more dynamic energys.
Advantages of higher stability is because d
1Can continue increases, and not facing to quality m
aThe minimizing of compression stress.An advantage of the invention is that it might only use the vibration frequency of resonator device conditioning equipment.Therefore operating frequency can move to outside the low-frequency range largely with one, thereby makes it be easier to use d
1The damping low frequency signal, and can damping do not have the compressed signal (being easier to introduce a high channel filter) of upper frequency.Therefore it be easier to increase damping d
1, and without any negative percussion in facing to the dynamic gain of compressed quality.
Flexibility.Because facing to quality m
aStatic force can pass through k
3Regulate, it might be regulated facing to quality m
aThe size of dynamic force.In Fig. 6, the air pressure in bellows can optimization to measure the size of power.Use resonator device, the amplitude of the dynamic fluctuation of table top and plummet [mm]/frequency [Hz] can be regulated.If equipment is to carry out greater functionality as beating oscillator, frequency can use this resonator device to reduce, with the amplitude [mm] of the dynamic fluctuation that increases table top and plummet.If equipment is to carry out greater functionality as one " vibration press ", frequency can use this resonator device to increase, thereby the amplitude [mm] of dynamic fluctuation is reduced.Such adjusting also can be reduced to the noise of environment, because impact to reduce, if with the identical dynamic size of the interior compressed air confining force of bellows.Best ratio depends on the object that is compacted herein, and whether its size and it use the vacuum vibration.
Safeguard and durability.Above-mentioned flexibility can cause the minimizing impacted.It has reduced the wearing and tearing of equipment and has reduced noise level significantly.
Dynamic energy to the minimizing of environment
Vibration frequency is regulated near a frequency by improved equipment, faces toward the dynamic gain maximum of anode mass at this moment.This also is such frequency, and this moment, table top and plummet were near opposed.Because plummet and table top are by spring k
3Be connected to each other, plummet will act on and compress table top upwards, and at this moment table top is on its road down to ground.Because the dynamic force that landing ground is transmitted is the summation of plummet and table top power, the plummet masterpiece is used in from the opposite direction of table top power herein, and the power that is sent to base plate will reduce.Consequently vibratory equipment is launched less dynamic energy to environment.In other words, dynamic energy will be stored in spring k
3In, at this moment table top is in lower position and plummet is in high position (spring k
3Being compressed) emitted energy is to the anode object subsequently for spring, and at this moment it extends (anode mass is compressed).Dynamic energy is stored in the inside of system largely, and less is emitted to environment.Herein importantly for spring k
3, should have minimal damping, thereby make the energy that is stored in the spring be used in the compression anode mass, rather than be converted into the energy of other form.Such as heat etc.
Dynamic gain facing to the anode mass increase
Use the dynamic gain that increases facing to anode mass, a possibility that increases facing to higher dynamic force of anode mass and/or low dynamic input power (eccentric force) is arranged here.
Stability
Use stable equipment, do not have the unordered fluctuation of table top and plummet here, it disturbs reposefully energize to compressed quality m
aLow resonant frequency when have at least one selection outside the operating frequency of removing according to equipment of the present invention importantly prevents the vibration of equipment under these frequencies.Also have importantly such designing apparatus, make dynamic gain minimum in these low-frequency ranges.Use the present invention, it might use resonator device to increase the operating frequency of equipment.Damping d
1Therefore can increase to reduce low-frequency fluctuation.A upper limit for damping is such position, faces toward quality m herein under the operating frequency of equipment
aDynamic gain reaches not significant to be reduced.
By regulating from spring k
3Static compression force, it might regulate the density of product compaction.The compacting time also can be used the static compression force of an increase and be reduced.The ability of this meaning equipment can increase.Use the equipment of suggestion, compression stress itself also can be regulated in compacting process, does so if desired.For example, may be effective to vibrate initially at a higher compression stress, it reduces subsequently, and in that it increases once more near the end of vibration processes.
The vibratory equipment of building according to the present invention can have device, thereby it might make them have identical density or identical physical size by vibrating electrode.Reaching this point can be by the equipment configuration measuring instrument, and how far plummet descended when it was recorded in vibration.Be placed on before vibration that the quantity of material is predetermined in the model, and take a sample subsequently to set up a value, it indicates by weight/volume.When the level of a regulation had reached, vibration can finish, and was identical thereby make physical external dimensions.
Moreover vibratory equipment can have device, and it comprises quality m in the volume generation vacuum that is limited by model assembly (plummet, table top and mould walls)
aThereby, make any gas clean-up go out model (vacuum vibration).Cause the density that increases like this, reduce the dangerous of cracking and in the higher temperature vibration etc.Fig. 6 illustrates this point and how to realize.The part of plummet is positioned at by mould walls Fv1, Fv2 and the vacuum chamber Vr inside that vacuum cover Vk forms completely.Vacuum cover can be connected to device by a pipe, and it produces vacuum in vacuum cover, such as being a fan or similar device (not shown).The remainder of whole plumb mass (york piece and resonator device Ve) is positioned at the outside, but is fixedly attached to a part of Ld of plummet with bolt B 1, B2, and it is in the vacuum chamber Vr.Cause minimum possible vacuum chamber like this, and the time of bleeding can be the shortest.Bolt must have as far as possible little total cross section, thereby makes vacuum have at least " suction effect " possible on york piece.Meanwhile, bolt must have sufficient size, and like this location makes that to connect be firm, and the moment of torsion of york piece is in reasonable range.
As quality m
aBe compacted when vibration, york piece will be near vacuum cover.Therefore must have beeline by plummet part to the york piece that is in the vacuum chamber, this distance can reduce, if vacuum cover also has telescopicing performance.The total height of vibratory equipment can reduce, yet will be by integrated resonator device in york piece.
