Fig. 1~10B has shown the different aspect of the gyratory compactor that meets one embodiment of the invention, by Reference numeral 10 expression gyratory compactors.This equipment 10 generally includes the framework 100 of having determined axis 150.Framework 100 is configured to be combined with pressure ram 200, and pressure ram 200 can move along axis 150.Relative with pressure ram 200 is pivo table member 300, and pivo table member 300 is also alignd with axis 150 and rotated around axis 150.But offset component 400 is arranged between pressure ram 200 and the pivo table member 300.With framework 100 co-operate, but the overall area between offset component 400 and the pressure ram 200 has determined to be used to receive the mold well 500 of mould 600.Equipment 10 also comprises mould maneuvering device 700, and it is configured to receive and handle mould 600 in mold well 500.Equipment 10 also is assembled with control system 800, and when being contained in mould 600 in the mold well 500, described control system 800 interacts with mould 600.
In a preferred embodiment of the invention, framework 100 comprises a plurality of elements 110 that for example tightened together by securing member, cementing agent, welding or other suitable mode that meets spirit and scope of the invention.Those skilled in the art know that and will continue to introduce in detail be, for the operation of equipment 10, accurate and accurate element alignment is very crucial, static and dynamic in, must keep this aligning.During gyratory compaction, multiple stress is applied on the framework 100, thus further require some frame elements 110 can handle with some other element 110 is of living in ought to the different stress of power.In addition, a device parameter must considering in the design of equipment 10 and structure is a weight.
Thereby, preferably can customize special frames parts 110 structures fixing and/or that strengthen, simultaneously, reduce parts 110 quantity to greatest extent, so that optimize the structure of framework 100.Some preferred embodiments of the invention have been utilized the one or more parts 110 with composite structure.For example Fig. 8 has shown the parts 110 that are made of a plurality of Individual components, and wherein one or more in these Individual components comprise two copline sheet metals that combined by welding, bonding, securing member or any other suitable mode.Just in these parts one can be configured such that and any wall, side or other definite surface can be made up of at least two copline sheet materials that tighten together.Yet, shown in the structure of parts 110 be not limited thereto because those skilled in the art can understand easily, the composite structure of parts 110 can comprise plural sheet material, also can comprise the sheet material of forming by many different materials, for example metal, polymkeric substance or other compound.In addition, composite structure also can be applied in parts 110 for example selectively only to be needed under the situation that spot welding strengthens, thereby only the part of parts 110 can comprise above-mentioned composite structure.And, also can use other measure to stop the adjacent sheets of compound to move relative to each other, for example, adjacent sheets can comprise interlocking joint or other physical construction (not shown), so that reduce or the prevention relative motion.Thereby, utilize the embodiment of the invention of composite structure will alleviate the weight of framework 100 significantly, thereby, resist under the prerequisite that is applied in the stress desirable strength not sacrificing in 10 operating periods of equipment, can optimize the structure of frameworks 100 with the element 100 of minimum number.
As mentioned above, for the operation of equipment 10, the accurate of its parts is very crucial with accurately aiming at, and as hereinafter describing in detail, these parts separate with respect to framework 100, must fit together, so that the equipment 10 that acquisition has predetermined function.The assembling of gyratory compactor requires experienced tradesman, complicated alignment tools and the particular step that is used for the suitable assembling of gyratory compactor and is fit to aim at usually.If gyratory compactor is dismantled so that keep in repair or move, this measure will often require repetition.The shortcoming of these requirements and step is apparent to those skilled in the art.Thereby other preferred embodiment of the present invention utilizes one to aim at step in the operation of making framework 100, in some cases, utilizes one to aim at step when other parts of manufacturing equipment 10.More particularly, in making framework 100 processes, one or more parts 110 are by the clamping of anchor clamps (not shown), and each anchor clamps special configuration one-tenth keeps parts 110 with particular kind of relationship and aims at.Particular kind of relationship is usually corresponding to the affirmation of framework axis 150, though other benchmark that relates to equipment 10 also can be relevant with particular jig.It is attached thereto that one or more parts 110 also can have one or more alignment member (not shown)s, or relevant with it, or aligning parts also can form by the cooperation between the parts 110.
On anchor clamps, parts 110 can for example be fixed together by welding, cementing agent, securing member etc., thereby form framework 100 or form a subassembly.At whole framework 100 under the situation that forms on the anchor clamps, framework 100 after completion is when anchor clamps are removed, and the parts 110 that form framework 100 will compatibly be aimed at, in addition, alignment member will serve make framework 100 with attached to other component alignment on the framework 100, with forming device 10.By parts 110 are arranged on the anchor clamps, form the subassembly of framework 100, after pulling down from anchor clamps, this subassembly will compatibly be aimed at, described alignment member will be used to make this subassembly to aim at respect to framework 100 simultaneously, or with one or more attached to other component alignment on the framework 100, thereby forming device 10.In certain embodiments, also can have the aligning parts (not shown) attached to other parts with forming device 10 on the framework 100, its corresponding to and can interact with the alignment member relevant with framework 100.Thereby, by using anchor clamps, in some cases, alignment member, experienced technician, special aligned instrument and step be can reduce or cancel in the assembling of gyratory compactor or during ressembling, time and the cost relevant also can be reduced with a large amount of and complicated assembling or the process of ressembling.
As Fig. 1~3,5, shown in the 6A and 7, framework 100 is configured to ccontaining pressure ram 200, thereby pressure ram can move along axis 150, with respect to by mould 600 that equipment 10 received and axial compressive force is provided.Thereby have in some cases cylindrical internal surface mould 600 must with the combining of equipment 10, thereby pressure ram 200 can extend through first end 610 of mould 600, and applies required axial compressive force along the longitudinal axis 620 of mould 600.Yet mould 600 also must rotate with the use of axial compressive force synchronously, so that realize and simulation paving machine or the rolling of other gas booster compressor on material surface.In order to obtain the required rotation of mould 600, second end 630 typically laterally moves, thereby longitudinal axis 620 is with respect to definite axis 150 inclination special angles 640 (are referred to herein as die angle by the motion of pressure ram 200, the anglec of rotation or angle of rotation), for example as shown in Figure 2.Because axial compressive force is applied by pressure ram 200 along axis 150, the transversal displacement of second end 630 of mould 600 is to move in the orbital motion of axis 150.Because mould 600 is constrained to around axis 150 by pressure ram 200 away from second end 630 and trend towards first end, 610, the second ends 630 and will cause mould 600 in equipment 10, to rotate around the orbital motion of axis 150.This operating characteristic or equipment 10 are referred to herein as " gyratory compaction " operation of sample 50.
According to a preferred embodiment of the present invention, as Fig. 2, shown in 3 and 5~7.But gyratory compactor 10 also comprises the offset component 400 that operably combines with framework 100, and it is relative with pressure ram 200 usually.But framework 100, pressure ram 200 and offset component 400 cooperate, and determining can be with mould 600 ccontaining mold well 500 within it.But offset component 400 can laterally move from axis 150, thereby cooperates with pressure ram 200 and mould 600, to determine the rotation angle 640 around the point of rotation 650.But the point of rotation 650 usually with central point 205 correspondences of pressure ram 200 ends relative (herein, further describe be foot 245) with offset component 400, maybe can be defined as the point of crossing of the axis 150 of the longitudinal axis 620 of mould 600 and framework 100.
For mould 600 rotates as required, but offset component 400 also comprises combination support component 420 thereon.Support component 420 is configured to a butt hemisphere usually, the circumferential stayed surface 440 that comprises plane surface 430 and have arch formula profile.Though according to demand, the arch formula profile of stayed surface 440 can be by many different modes structures, and under certain conditions, the arch formula profile of stayed surface 440 can be determined by a radius.Thereby, second end 630 of mould 600 also comprises with longitudinal axis 620 being the stayed surface 660 at center, and stayed surface 660 is configured to respect to stayed surface 440 complementations, when stayed surface 440,660 in conjunction with the time, form a kind of ball and spigot and faucet joint, thereby second end 630 of mould 600 is restrained basically, but rotation along with mould 600, allow stayed surface 660 to pivot, thereby center of rotation 410 is along longitudinal axis 620 settings of mould 600 around the center of rotation 410 of support component 420 center of rotation of second end 630 of mould 600 (otherwise be called).Center of rotation 410 is corresponding to the central point of spheroid, and this spheroid is stacked in and corresponding to the butt hemisphere that forms support component 420.Thereby, because mould 600 rotates and because support component 420 is also brought into play the function that second end 630 to mould 600 retrains, can determine the transversal displacement of the center of rotation 410 of support component 420 from framework axis 150 easily around support component 420.Thereby successively, the angle of rotation 640 and the point of rotation 650 can be determined easily with static schema and with the dynamic mode of 10 operating periods of equipment.
In case laterally move from framework axis 150, but offset component 400/ support component 420 must be with the orbital motion activity around framework axis 150, thereby provides mould 600 required rotation.Thereby in one embodiment of the invention, but offset component 400 combines with rotating element 300 and or by rotating element 300 supports, wherein rotating element 300 is constructed to be permeable to rotate around framework axis 150.But offset component 400 is configured to laterally move with respect to rotating element 300.Rotating element 300 also combine with nonrotational plate 320 and or support by nonrotational plate 320, for example shown in Fig. 5 and 7, rotor plate 320 can be combined on the framework 100 or be integrally formed with framework 100.Plate 320 has first surface 330 and the opposed second surface 340 of pointing to rotating element 300.In one embodiment, plate 320 also can have the groove 350 of an extend past first surface 330, and groove 350 is positioned at the outside of rotating element 300 on being arranged in radially.In the case, groove 350 can also comprise the one or more passages 360 that extend towards the second surface 340 of plate 320 from groove 350.
Because but offset component 400 can interact closely with sample 50, but may build up around offset component 400 and rotating element 300 undesirably from the residue of sample 50 in certain embodiments, but particularly when offset component 400 and rotating element 300 are arranged on the lower end of mold well 50.Thereby in the case, described groove 350 is set is used to collect sample residues, the outside that one or more passages 360 outwards are directed to sample residues from groove 350 equipment 10 is set simultaneously.In certain embodiments, a cleaning element 370 that combines with rotating element 300 is set also, combines thereby can rotate with groove 350.This cleaning element 370 further is constructed with and the corresponding profile of the xsect of groove 350, thereby rotate by rotating element 300, cleaning element 370 is around groove 350 towings, is directed to the sample residues in the groove 350 in one or more passages 360 and exports to the outside of equipment 10.In some cases, but but cleaning element 370 be configured to laterally move with respect to rotating element 300 and do not interfere mutually with offset component 400 along with offset component 400.Thereby, cleaning element 370 can cooperate with groove 350 and one or more passage 360, along with the operation of equipment 10, sample residues is removed from mold well 500, thereby reduced or eliminated when equipment 10 is idle by the artificial demand of removing sample residues in the mold well 500.
As mentioned above, gyratory compactor 10 purpose is to be rotated and to apply axial compressive force to sample 50 along with sample 50.As shown in Figure 6A, provide required axial compressive force by pressure ram 200, pressure ram 200 combines and is configured to provide force of compression along axis 150 with framework 100.Typically wish the numerical value of described axial compressive force is accurately measured, use dynamometer to realize above-mentioned measurement usually.Yet if bear eccentric or the non axial load that applies, dynamometer may show inaccurate numerical value, in gyratory compactor, along with mould rotates, may produce this eccentric force.Thereby, a good aspect of the present invention comprises the dynamometer 210 between the head 230 of the ram tube 220 that is combined in pressure ram 200 and pressure head, ram tube 220 is configured to receive with high tolerance ground the cylindrical section 240 of the head of pressure head 230, thereby ram tube 220 and cylindrical section 240 interact on the length wishing.First end 250 of cylindrical section 240 extends in the ram tube 220, and second end 260 reaches the outside.
Dynamometer 210 is arranged in the ram tube 220, thereby interacts with first end 250 of cylindrical section 240.Directly interact with first end 250 though show dynamometer 210, for example when when dynamometer 210 and first end 250 are provided with the packing ring (not shown) each other, dynamometer 210 and the 250 indirect interactions of first end also are feasible.Dynamometer 210 preferably is arranged to be positioned as close to first end 250.In addition, preferably retraining dynamometer 210 can not must break away from the head 230 of pressure head along the axial-movement of ram tube 220.For example, ram tube 220 can comprise an installation elements 270, and the diameter by changing ram tube or with other machinery that is fit to can not be along the head 230 of ram tube 220 axially-movables away from pressure head thereby limit this installation elements 270.Dynamometer 210 is fixed on the installation elements 270, and is securely fixed in the ram tube 220.The pressure that is applied on the sample 50 by the head 230 of pressure head is sent to dynamometer 210 by cylindrical section 240, it will be understood by those skilled in the art that this dynamometer determines to be applied to the pressure on the sample 50.Yet according to a good aspect of the present invention, the action length of the mutual extension between head 230 cylindrical sections of ram tube 220 and pressure head and high-precision tolerance are used for disperseing during mould 600 rotates any head 220 by ram tube to be sent to eccentric force on the head 230 of pressure head.Thereby any eccentric force that acts on the head 230 of pressure head will not be sent on the dynamometer.
Thereby dynamometer 210 only experiences the axial load of concentrating from the head 230 of pressure head, and according to embodiments of the invention, dynamometer 210 is configured to be illustrated in more accurately during the gyratory compaction by pressure ram 200 and is applied to axial compressive force on the sample 50.Those skilled in the art will recognize, the axial compressive force that is applied on the sample 50 also can adopt alternate manner to determine, for example adopt transfer the assignee of the present invention, denomination of invention is No.10/210 for " being used for determining the rotation angle of gyratory compactor and/or the method and apparatus of pressure ", application number, mode described in 020 the United States Patent (USP), the content of this United States Patent (USP) is in conjunction with in the present invention.
Those skilled in the art will recognize that as shown in Figure 6A pressure ram 200 can have the different operating mechanism that is used to apply desired force of compression.And dynamometer 210 also can be arranged to the head 230 away from pressure head.For example said structure can comprise that the head 230 that forces pressure head breaks away from ram tube 220 so that the hydraulic system (not shown) of force of compression to be provided.Fig. 6 B has shown another example that applies the machinery of force of compression by pressure ram 200.As shown in the figure, ram tube 220 can be configured within it by the ccontaining ram shaft 225 of near-end 220b.Ram shaft 225 comprises relative two ends 225a, 225b.The end 225b that is arranged on the ram shaft 225 of ram tube 220 outsides is configured to the cylindrical section 240 of the head 230 of ccontaining pressure head.The other end 225a of ram shaft 225 comprises internal thread (end of ram shaft 225 can processed screw thread or ram shaft 225 can comprise the nut element that operationally combines with it), thereby is configured to receive the spiral part 235a of the leading screw driving device 235 that engages with the far-end 220a of ram tube 220.Yet leading screw driving device 235 can adopt the multiple mode different with illustrated embodiment to engage with ram tube 220 and ram shaft 225.In the case, dynamometer 210 is arranged to the head 230 away from pressure head, and engages with the drive part 235b of leading screw driving device 235, thereby leading screw driving device 235 is measured with respect to the axle pressure that the head 230 of ram shaft 225, pressure head is produced.Thereby same as described above, the interactional length of the extension between ram tube 220 and the ram shaft 225 and accurate tolerance are used for disperseing during mould 600 rotates any drive part 235b by leading screw driving device 235 to be sent to eccentric force on the dynamometer 210.Thereby any eccentric load that acts on the head 230 of pressure head will not be sent on the dynamometer 210, and dynamometer 210 will only experience the concentrated axial load from the head 230 of pressure head.Therefore dynamometer 210 will be represented to act on axial compressive force on the sample 50 by pressure ram 200 in gyratory compactor operating period more accurately.
As shown in Figure 2, equipment 10 also comprises and can be arranged in the mould 600 and towards first disk 670 of second end 630.The mould 600 and/or first disk 670 are configured to first disk 670 temporarily is stuck towards second end 630, thereby cooperate to hold sample 50 with mould 600.For example first disk 670 can temporarily be retained in the mould 600 by the ring 615 that engages with mould 600 inside surfaces, thereby when mould 600 inserts mold well 500 or takes out from mold well 500, sample 50 is retained in the mould 600.In case apply force of compression by pressure ram 200, first disk 670 moves and contacts with the plane surface 430 of support component 420 along mould 600.The head 230 of pressure ram 200 also comprises attached to the foot 245 on cylindrical section 240 second ends 260, or attached to the foot 245 on the outer ram shaft 225 of ram tube 220.In some cases, foot 245 plays a role as " disk ", and relative with first disk 670 in the mould 600, thereby sample 50 is arranged between the foot 245 and first disk 670, and is arranged in the mould 600.In another case, second disk 680 (being illustrated by the broken lines) can be arranged in the mould 600, and between the foot 245 and sample 50 of pressure ram 200, thereby foot 245 does not act directly on the sample 50.Yet as mentioned above, the central point 205 of foot 245 has been determined the point of rotation 650 of mould 600, in gyratory compaction operating period, and along with sample 50 is compressed, foot 245 more close support components 420.Thereby foot 245 can be defined as " inactive ", because first end 610 of mould 600 is unfettered, and provides the fixing point of rotation 650, and owing to foot 245 can not laterally move, thereby during sample 50 is compacted, keep rotation angle 640.Equally, the common rotation angle 640 that requires to keep constant value will change along with the compression of sample 50 during compacting operation.
Thereby the preferred embodiment of the present invention also provides for example closed-loop control system shown in Fig. 3 and 4 800, but so that at gyratory compaction operating period watch-keeping rotation angle 640 and the dynamic transversal displacement of adjusting offset component 400, thereby, keep the special value of rotation angle 640 along with sample 50 is compressed.More particularly, control system 800 comprises controller 810 and die angle checkout equipment 820.As shown in Figure 5, die angle checkout equipment 820 comprises a pair of sensor 830 aligned with each other and that be spaced a distance along framework axis 150.Sensor 830 is configured to contact with the outside surface of mould 600, for example can be feeler, proximity sensor, or other contact or non-contact sensor or their combination that is fit to, those skilled in the art will recognize easily, can determine the rotation angle 640 of mould 600 according to the difference of absolute distance between each sensor 830 and mould 600 outside surfaces.Yet in some cases, can for example be used for determining that the equipment of die angle determine rotation angle 640 from uses in the mould 600, this equipment is for example at the U. S. application No.10/210 of above-mentioned combination as the application's reference, is disclosed in 020.Those skilled in the art also will recognize, also can adopt alternate manner to determine rotation angle, for example along mould 600 vertically between determine.
Sensor 830 is connected with controller 810 communications, and controller 810 is configured to the displacement of pressure ram 200 and foot 245 is sent to mould 600, thereby for example guarantees to be applied on the sample 50 by the axial compressive force of the measured regulation of dynamometer 210.Controller 810 also is configured to read by the shift value of sensor 830 expressions or near value, and definite actual mold angle 640.Controller 810 can also compare actual mold angle 640 and regulation or desirable die angle, but instructs offset component 400 transversal displacement adjustment until obtaining desirable die angle then.In some cases, force of compression and the die angle 640 on the controller 810 structure paired sampleses 50 measured and then adjusted simultaneously if desired.In other cases, measurement and any necessary adjustment can be carried out in segmentation, maybe can carry out with this frequency, promptly keep force of compression and die angle near real-time.Those skilled in the art understand easily that also according to complicacy and the automaticity or the desirable user friendliness of terminal user of equipment 10 controlled variable that requires, controller 810 can adopt multiple different form.But though the transversal displacement of definite employing offset component 400 of rotation angle described herein 640, it should be understood that the position control that can adopt multi-form realization offset component 400, for example according to Cartesian coordinate system and for example use X-Y table.In certain embodiments of the invention, by using the change in polarity scope table of two parallel concentric plates (but offset component 400 and rotating element 300), rho theta system is used, thereby according to this rho theta system, rotate along with but offset component 400 and rotating element 300 all center on axis 150, but offset component 400 is converted to the eccentric position with respect to rotating element 300.Yet, above-mentioned example does not limit the present invention, because equipment 10 can have many other structures, these structures all can provide the required transversal displacement of mould 600 second ends 630 and apply second end 630 around axis 150 desired orbital motions, so that produce the rotation of mould 600.
Also considered the economy of equipment 10 in embodiments of the present invention.The mould 600 that for example has disk 670 and a sample disposed thereon 50 may sink and be heavy very much.Thereby preferably reduce and be assembled to mould 600 in the mold well 500 and make mould 600 and required operations such as support component 420 and pressure ram 200 alignings.According to the preferred embodiment of the present invention, for example shown in Fig. 9 A~9C, equipment 10 also be equipped be used for mould 600 is ccontaining and be arranged on mould maneuvering device 700 in the mold well 500.At first, mould 600 must be inserted in the mold well 500, then second end 600 be reduced until combining with support component 420.Framework 100 also comprises classification element (staging member) 160, and it is configured at certain height mould 600 be received thereon, thereby second end 630 is than horizontal surface 430 height of support component 420.Each end 610 of cylindrical mold 600,630 also can comprise the flange 690a that extends radially outwardly, external diameter is bigger than the external diameter of mould 600,690b is (in any embodiment of described the present invention, mould 600 also can comprise among flange 690a or the 690b one or both, as long as be suitable to disclosed embodiments of the invention.In certain embodiments, the flange 690a of mould 600 first ends 610 comprises a pair of formation flat 695a of portion thereon, the external diameter of gap ratio flange 695a is little between the described a pair of flat 695a of portion, and first end 610 of each flat 695a of portion and mould 600 is separated by the 695b of edge portion of flange 695a.
Usually pitch the 705 pressure ram ends of being arranged to towards mold well 500 by a pair of attached to shown in Fig. 9 B, receiving of forming of the interval tip 710 on the horizontal expansion support component 715, shown in Fig. 9 A and 9C.As mentioned below in one embodiment, handle described reception fork 705 and engage, and move axially along axis 150 with pressure ram 200 cooperations with framework 100.Receiving fork 705 is configured to when mould 600 is arranged on the described classification element 160 and slides to mold well 500, and first end 610 of mould 600 keeps gap (clear) with the foot 245 of pressure ram 200, and the flat 695a of portion of flange 690a is contained between the tip 710.Thereby the tip 710 peaceful 695a of portion cooperations, guarantee that mould 600 is contained in the mold well 500, and be in desirable rotational orientation.Support component 715 can further be configured to cooperate with prong head 710, thereby in mould 600 is contained in fork 705 time, mold axis 620 and framework axis 150 coaxial cables.Can guarantee the aligning that is fit to by multiple mode, for example by pitching 705 physical construction or the sensor (not shown) that is fit to by being configured to when mould is in desired position, detect.In the time of in mould 600 compatibly being inserted fork 705, mould 600 is no longer supported by classification element 160, but is suspended on support component 420 tops, and the 695b of edge portion by flange 690a is supported pitching on 705 the tip 710.
In case mould 600 is inserted in the fork 705, pressure ram 200 can be moved to support component 420 by controller 810 guiding.Thereby fork 705 will also move to support component 420, thereby second end 630 of reduction mould 600 is until combining with support component 420.When thereby mould 600 fully reduces moulds 600 and supported by support component 420, fork 705 also will move axially along mould 600, leave from flat 695a of portion and the lip 695b of flange 690a.Pressure ram 200 is advanced further and will causes foot 245 to enter first end 610 of mould 600, and being advanced further of pressure ram 200 can provide necessary axial compressive force on sample 50, and rotation angle 640 is determined subsequently then.
In some cases, mould maneuvering device 700 can also comprise and fork 705 fastening apparatus that combine 720, and its second end 630 that is configured to keep in gyratory compaction operating period mould 600 fully contacts with support component 420.First end 610 of fastening apparatus 720 and mould 600 is configured to be similar to the structure of above-mentioned support component 420/ second end 630.Just fastening apparatus 720 is configured to the truncation hemisphere usually, and it comprises the inner 725 and the circumferential stayed surface 730 with camber profile.Thereby first end 610 of mould 600 also comprises with longitudinal axis 620 being the stayed surface 665 at center, and stayed surface 665 is constructed with the shape with stayed surface 730 complementations of fastening apparatus 720.When stayed surface 665,730 in conjunction with the time, form a kind of ball and spigot and faucet joint, thereby along with mould 600 rotates, first end 610 of mould 600 can rotate around fastening apparatus 720.Yet, also require the foot 245 of first end, the 610 authorized pressure pressure heads 200 of mould 600 to enter in the mould 600, to provide force of compression to sample 50.Thereby fastening apparatus 720 also has usually the hole 735 corresponding with the ram shaft 225 of cylindrical section 240 or pressure head 230, and hole 735 is configured to allow cylindrical section 240 or ram shaft 225 freely to pass through.Fastening apparatus 720 also limits the slot part 740 that extends and be arranged to contact with hole 735 from inner 725, slot part 740 is configured to corresponding with the foot 245 of pressure head 230, thereby when pressure head 230 when mould is withdrawn, foot 245 enters slot part 740, and concordant, thereby form and inner 725 plane surfaces that link to each other with inner 725.
As mentioned above, second end that fastening apparatus 720 is configured to keep in gyratory compaction operating period mould 600 fully contacts with support component 420, and equipment 10 can also comprise one or more bias voltage equipment 900 such as types of springs equipment or other suitable equipment, described bias voltage equipment operationally is combined between framework 100 and the fastening apparatus 720, be used for fastening apparatus 720 is elastically biased toward with first end 610 of mould 600 and combine, thereby force mould 600 to abut against support component 420.Be in suitable position by keeping mould 600 with respect to support component 420, thereby in gyratory compaction operating period, rotation angle 640 can be kept better.As implementing in embodiments of the present invention, for example framework 100 can comprise the fixture 180 of one or more adjacent pressure pressure heads 200, thereby one or more bias voltage equipment 900 is arranged between one or more fixtures 180 and the fastening apparatus 720.In some embodiments of the invention, fork 705 engages with fastening apparatus 720, wherein the both by one or more bias voltage equipment 900 to support component 420 bias voltages.Thereby when the foot 245 of pressure ram 200 is withdrawn fully, thereby fastening apparatus 720 and fork 705 be pulled abut against one or more bias voltage equipment 900 until fork 705 be in be fit to the position receive from classification element 160 moulds 600 or mould 600 from pitch 705 be transplanted on classification element 160 till.Thereby when mould 600 insertions were pitched 705, foot 245 can move in first end 610 of mould 600.One or more then bias voltage equipment 900 force fastening apparatus 720/ fork 705 trend support components 420, thereby shift fork 705 moves mould 600 to such an extent that engage with support component 420.When mould 600 with after support component 420 combines, being moved further of foot 245 moved fork 705, thereby pitching 705 breaks away from the flat 695a of portion of flange 690a and the 695b of edge portion and to combine, one or more bias voltage equipment 900 force fastening apparatus 720 to engage with mould 600 first ends 610 simultaneously, then, first end 610 of mould 600 is supported by fastening apparatus 720, supports and can't help to pitch 705.
Yet when fork 705 combined with the flat 695a of portion disengaging, mould 600 can always not wish that mould 600 is in gyratory compaction operating period rotation in gyratory compaction operating period rotation.Thereby in Fig. 6 A illustrated embodiment, can not for example can on stayed surface 730, be determined a groove or jack 770 by the fastening apparatus 720 that rotates under one or more bias voltage equipment 900 or other device effect usually.The stayed surface 665 of mould 600 or flange 690a go up the position can correspondingly comprise a pin element 780, when being combined in fastening apparatus 720 on the mould 600, pin 780 can insert in the jack 770, thereby, the interaction of pin 780 and jack 770 stops mould 600 to rotate, but still allow stayed surface 665,730 to interact, thereby allow mould 600 to rotate with respect to fastening apparatus 720 as required.Yet those skilled in the art will recognize easily, when can't help to pitch 705 supports, can utilize many different modes to stop mould 600 to rotate around axis 150, and said structure does not limit the present invention.For example selling 780 can engage with fastening apparatus 720, on mould 600 jack is set simultaneously.
In addition as mentioned above, because the embodiment of the invention comprises the point of rotation 650, according to moving of pressure ram 200, this point of rotation motion, if in gyratory compaction operating period, obtain and keep rotation angle 640, first end 610 of mould 600 just can transversal displacement.Thereby shown in Fig. 9 A, equipment 10 can comprise a transversal displacement equipment 920 that is arranged between fastening apparatus 720 and the one or more bias voltage equipment 900, thereby allow fastening apparatus 720 must allow first end 610 of mould 600 freely laterally to move as required simultaneously against support component 420 mould 600 bias voltages.For example fastening apparatus 720 by one or more be arranged between itself and first movable plate 925 first sliding mechanical 930 and attached on first movable plate 925, first movable plate 925 by one or more be arranged between itself and second movable plate 935 second sliding mechanical 940 and attached on second movable plate 935.Second movable plate 935 is attached on one or more biased elements 900.In some cases, first sliding mechanical 930 is arranged to vertical with respect to second sliding mechanical 940, thereby allows fastening apparatus 720 freely laterally to move with respect to one or more biased elements 900.Yet those skilled in the art will recognize that free laterally the moving of fastening apparatus 720 can be realized that the structure that this place is introduced does not limit the present invention by multitude of different ways.
Those skilled in the art will recognize that some parts of constitution equipment 10 can constitute in different ways, or cooperate with other parts in different ways, to obtain same as described above or similar effects.For example in certain embodiments of the invention, shown in Figure 10 A and 10B, substitute and combine with fastening apparatus 720, fork 705 can engage with pressure ram 200, or be independent of pressure ram 200 and fastening apparatus 720 and operate, thereby fork 705 is independent of fastening apparatus 720 ground and moves.In some cases, fork 705 can be configured to move accordingly with the foot 245 of pressure head 230.In this structure, as mentioned above, fork 705 can be arranged in the equipment 10, receives mould 600 or allows mould 600 to be moved out of.Yet for example, the flange 690a of first end 610 of mould 600 can be configured to the not flat 695a of portion, thereby when mould 600 is received by fork 705, flange 690a self supporting mould 600, when mould 600 inserts mold well 500, in order to ensure the rotation that is fit to of mould 600 towards, for example mould 600 can determine on the outer surface that one extends axially groove 950, support component 715 or pitch other element of 705 and also can have the pin element 955 that combines and from then on extend with groove 950, thereby when mould 600 was received by fork 705, pin 955 can be bonded in the groove 950.In the case, pin element 955 is configured with respect to groove 950, thereby along in the mould 600 axial location scopes or in the scope of mould 600 rotation angle 640, kept around suitable between the two joint that axis 150 rotates at gyratory compaction operating period prevention mould 600 at fork 705.For example pin element 955 can be configured in gyratory compaction operating period corresponding with the central point 205 (point of rotation 650) of the foot 245 of pressure head 230 with the bonding station of groove 950 along mould 600.
Still shown in Figure 10 A, die angle checkout equipment 820 also can be combined in support component 715 or pitch on other element of 705, thereby sensor 830 is spaced a distance and adopts the aforesaid way operation along 150 the direction of paralleling to the axis, to determine rotation angle 640.Sensor 830 can be contact type or noncontact type sensor or any sensor that is suitable for realizing the above-mentioned functions type.In some cases, sensor 830 can be determined to be configured to before suitable signal is provided to controller 810, and when mould 600 is in specific limit, and controller 810 allows equipment 10 to operate in response to this signal subsequently.In the case, die angle checkout equipment 820 for example bring into play show that mould is fit to insert and mold well 500 aim at or with function such as equipment 10 safety interlocks.
Figure 11 A~11D shows the mould maneuvering device 700 that is used to receive mould 600 and handles mould 600 in mold well 500.In this embodiment, mould maneuvering device 700 comprises first installing plate 1100 with a hole 1110, and the cylindrical section 240 of pressure ram 200 or ram shaft 225 are passed this hole and extended.First installing plate 1100 is attached on the framework 100, thereby it is opposite to be arranged in the mold well 500 head 230 with pressure head.Second installing plate 1200 also has a hole 1210, and the cylindrical section 240 of pressure ram 200 or ram shaft 225 are passed this hole and extended.Second installing plate 1200 is arranged between the head 230 of first installing plate 1100 and pressure head.Second installing plate 1200 is engaged with first installing plate 1100 by one or more bias voltage equipment 1250 (having shown 4 this bias voltage equipment 1250 in the present embodiment), and described bias voltage equipment 1250 is configured to must be away from first installing plate 1100 with second installing plate, 1200 bias voltages.
1210 both sides combine with second installing plate 1200 respectively a pair of pivotable member 1300 pivotly in the hole, and pivotable member 1300 is constructed with parallel pivotal axis 1310.Each pivotable member 1300 is arranged on second installing plate 1200 relative with first installing plate 1100, and has a central pivot, thereby inwardly 1250 extensions towards the hole of a position of pivotable member 1300, the position extends outward from second installing plate 1200 relatively simultaneously.Each pivotable member 1300 also comprises the pivot element 1350 that engages and extend to first installing plate 1100 or framework 100, and each pivot element 1350 is configured to make different pivotable member 1300 to pivot and/or limit the slewing area of different pivotable member 1300.
Those skilled in the art will recognize that as implied above and described, second installing plate 1200 can be with respect to 1100 motions of framework 100/ first installing plate, pivotable member 1300 can be rotated with respect to second installing plate 1200.Thereby, when second installing plate, 1200 biased equipment 1250 bias voltages must be away from first installing plate 1100, second installing plate 1200 and/or pivot element 1350 be with respect to first installing plate 1100 constraint pivotable member 1300, thereby cause pivotable member 1300 position that stretches out to be rotated towards first installing plate 1100 around pivotal axis 1310.Pivot element 1350 also is used to limit the rotation of pivotable member 1300, limits the motion of second installing plate 1200 away from first installing plate 1100.And because the cylindrical section 240 or the ram shaft 225 of pressure ram 200 extend through first and second installing plates, the head 230 of pressure head can make pivotable member 1300 pivot in opposite direction.Just be in complete retracted position and during away from support component 420 when the head 230 of pressure head, the head 230 of pressure head will be supported on the part that pivotable member 1300 extends internally, thereby make pivotable member 1300 along oppositely rotating around pivotal axis 1310.Simultaneously, the head 230 of pressure head makes second installing plate 1200 towards 1100 motions of first installing plate.
Each pivotable member 1300 comprises and leaves the track 1000 of second installing plate 1200 that each track 1000 comprises a supporting projection that extends internally 1010 spaced apart.When the head 230 of pressure head was in complete retracted position, shown in Figure 11 A and 11B, track 1000 was fully spaced apart, thereby can receive the flange 690a of mould 600 first ends 610 between track 1000.Supporting projection 1010 is spaced apart from each other, and its spacing is bigger than the external diameter of mould 600, but littler than the external diameter of flange 690a.When the head 230 of pressure head is in complete retracted position, described supporting projection 1010 is positioned on the enough height in classification element 160 tops, thereby when forcing mould 600 to enter in the mold well 500, the supporting projection 1010 of track 1000 receives and supporting mould 600 by flange 690a, thereby second end 630 is than plane surface 430 height of support component 420.The mold stop (not shown) combines with framework 100 and/or mould maneuvering device 700, thereby when the longitudinal axis 620 of mould 600 aligns with framework axis 150, prevents mould 600 to enter in the mold well 500 from classification element 160.In case mould 600 is inserted in the mold well 500 and by track 1000 and supports, can driving pressure pressure head 200, the beginning compacting operation.
In operation, the head 230 of pressure head is imported in first end 610 of mould 600.Along with the head 230 of pressure head enters in the mould 600, bias voltage equipment 1250 makes second installing plate 1200 away from first installing plate 1100, thereby second end 630 of mould 600 is descended, and combines with support component 420.Shown in Figure 11 A and 11B, the motions that the head 230 of pressure head enters in the mould 600 continuously allow pivot element 1350 to act on the pivotable member 1300, thereby the flange 690a that causes pivotable member 1300 and supporting projection 1010 to rotate into mould 600 separates.Mould maneuvering device 700 is configured to when supporting projection 1010 rotates into flange 690a with mould 600 and separates, and second end 630 of mould 600 is supported by support component 420.Thereby, descend and and the mould 600 of support component 420 combinations and along with pressure ram 200 begins to carry out compacting operation and unclamps between the mould maneuvering device 700 of mould 600, certain embodiments of the invention provide continuous basically conversion.At this point, pressure ram 200 further motion causes foot 245 to be positioned at mould 600, provides required axial compressive force to sample 50, and sets up rotation angle 640.
Because in mould 600 and support component 420 combinations, during pressure ram 200 beginning compacting operations, mould 600 is unclamped by mould maneuvering device 700, and mould 600 must remain on the position with respect to support component 420, thereby stops mould 600 to rotate around longitudinal axis 620.Thereby in some embodiment in conjunction with the described use Mould operation of Figure 11 A~11D equipment 700, as shown in figure 13, mould 600 comprises the intermediate flange 750 that is arranged between first end 610 and second end 630, and intermediate flange 750 also comprises the breach 755 that circumferentially extends along mould 600 outside surfaces.Anti-rotation piece 760 engages with framework 100 or is relevant, is configured to interact with the breach 755 of intermediate flange 750.In one embodiment, anti-rotation piece 760 be arranged in the mold well 500 and usually by bias voltage equipment 765 to mold well 500 export-oriented classification element 160 bias voltages.When with mould 600 in classification element 160 inserts mold well 500 time, anti-rotation piece 760 combines with intermediate flange 750, mould 600 rotations until anti-rotation piece 760 with till breach 755 combines.Simultaneously, mould 600 is received by mould maneuvering device 700, thereby, anti-rotation piece 760 also can be used to make the moulds 600 in the Mould operation equipment 700 to aim at and/or as mold stop, the expression mould compatibly inserts in the Mould operation equipment 700, thereby longitudinal axis 620 is aimed at framework axis 150.Thereby in case mould 600 is received by Mould operation equipment 700 and supported by track 1000, bias voltage equipment is kept anti-rotation piece 760 and is combined with breach 755, thereby stops mould 600 to rotate during compacting operation basically.
In the time of on remaining on mould 600 with respect to the position of support component 420, must also consider to stop mould 600 to leave support component 420.Just during compacting operation, mould 600 must be contained or is maintained in support component 420 and be fit to contact.Thereby in conjunction with some embodiment of the described use Mould operation of Figure 11 A~11D equipment 700 and shown in Figure 12 A and 12B, certain embodiments of the invention also comprise and are used at second end 630 mould 600 being fastened on containment equipment 850 on the support component 420.By this containment equipment 850 mould 600 is maintained on the suitable position with respect to support component 420,, can keep rotation angle 640 preferably in gyratory compaction operating period.Along with mould 600 rotates during compacting operation, second end 630 of mould 600 carries out orbital motion around framework axis 150.Thereby on any position of described track, the flange 690b of mould 600 second ends 630 has two radially relative position 860a, 860b on certain vertical height with respect to support component 420.Just any moment in orbit, the plane of aiming at and tangentially extend to the rotation center 410 of support component 420 along the longitudinal axis 620 of mould 600 will be intersected at 2 flange 690b with mould 600 second ends 630.860b has been determined around the radially opposite identical vertical position 860a of flange 690b with the joining of flange 690b in this plane.Yet those skilled in the art will recognize, because along with mould 600 rotations, stop mould 600 to rotate around longitudinal axis 620, along with centering on 150 orbital motions of framework axis, vertical position 860a that this is identical, but 860b rotates around flange 690b along giving offset component 400 identical rotation directions.
In one embodiment, containment equipment 850 comprises a pair of roller element 855 radially relative with respect to support component 420 that be mounted to.Roller element 855 is installed on the different mounting blocks 870, but each mounting blocks 870 can be around rotating with the different longitudinal extension pin element 875 of offset component 400 joints.Roller element 855 is installed on the different mounting blocks 870 by horizontal expansion axle 880.Mounting blocks 870 is configured to and can rotates, thereby roller element 855 can move from the primary importance shown in Figure 12 A and move to the second place shown in Figure 12 B, in primary importance, roller element 855 is arranged on the flange 690b, in the second place, roller element 855 and mounting blocks 870 are arranged on the outside of flange 690b diametrically.In primary importance, axle 880 is along the straight line setting that extends through rotation center 410, thereby roller element 855 is tangent with mould 600 outside surfaces.In the second place, roller element 855 and mounting blocks 870 are arranged to make mould 600 to rise from support component 420 without let or hindrance.
Mounting blocks 870 is by dissimilar arm 885a, and 885b is connected on the position control component 890a, but position control component 890a installs to such an extent that rotate around the longitudinal extension pin element 890b that engages with offset component 400.In one embodiment, position control component 890a and/or mounting blocks 870 can be biased into a normal rotational position, and for example roller element 855 is arranged to combine with flange 690b, or roller element 855 radially is arranged on the outside of flange 690b.In some cases, position control component 890a and/or mounting blocks 870 can be biased on two relative normal positions, and the transition between these positions allows other machinery of this bias voltage or equipment to determine by cam or in the every side of transfer point.Arm 885a, 885b is bonded between position control component 890a and the different mounting blocks 870, thereby, along with position control component 890a rotates along a direction, roller element 855 is moved into flange 690b and combines, when position control component 890a rotated in opposite direction, roller element 855 was removed from flange 890b simultaneously.
Those skilled in the art will recognize that before the beginning compacting operation, mould 600 must move to such an extent that combine with support component 420 and is fastened on the support component 420 by roller element 855.Simultaneously, stop mould 600 to rotate by anti-rotation piece 760 around longitudinal axis 620.But position control component 890a and mounting blocks 870 are fastened on not on the offset component 400 of rotation center 410 rotations.Thereby along with mould 600 rotations, but position control component 890a and mounting blocks 870 move in orbit with offset component 400, thereby roller element 855 is corresponding to same vertical height position 860a, 860b ground rolls around the flange 690b of mould 600, simultaneously mould 600 is fixed on the support component 420.
In some cases, equipment 10 can also comprise the pawl member 895 that combines and can combine with position control component 890a with framework 100.Just pawl member 895 can be mounted to, along with biased element 400 moves along the normal rotation direction under rotating element 300 effects in orbit, pawl member 895 initially contacts with position control component 890a, thereby and makes position control component 890a turn to roller element 855 to engage with flange 690b mould 600 is fastened on position on the support component 420.Can to the described pawl member 895 of position control component 890a position contacting bias voltage, or optionally pawl member 895 is driven into described contact position.In case the end compacting operation, roller element 855 must be disengaged with flange 690b, so that 10 dismountings of mould 600 slave units down.Thereby in one embodiment, pivo table member 300 can be along rotating in the opposite direction with normal rotation side.In the case, pawl member 895 can be configured to contact with position control component 890a, and cause position control component 890a to turn to roller element 855 and the out-of-gear position of flange 690b, thus pass through the withdrawal of pressure ram 200, allow mould 600 to be moved out of.
In certain embodiments of the invention, position control component 890a and/or mounting blocks 870 can engage with the limit switch (not shown) or with another kind of type detection mechanical engagement, determining when that position control component 890a has turned to roller element 855 and the out-of-gear position of flange 690b, and corresponding element 300 backward rotation that stop operating.In some cases, limit switch or other detect machinery can instruct or drive biased element 400 repositions, thereby the longitudinal axis 620 of mould 600 is aimed at again with framework axis 150.Thereby the rotation of rotating element 300 stops, roller element 855 combines with flange 690b disengaging, the state of biased element 400 reposition can be defined as enrollment status.In this enrollment status, can driving pressure pressure head 200, make it from mould 600 withdrawals, thereby cause mould maneuvering device 700 to begin mould 600 is risen from support component 420, thereby allow mould 600 from mold well 500, to shift out.
