Description
Technical field
The reconditioning of a kind of cutter for ring flaker of the present invention, the particularly method of reconditioning again, on this ring flaker, be fixed wtih a plurality of cutting tool grippers at the cutter ring, at these at least one cutters of cutting tool grippers process clamp mechanism difference clamping, cutter to be grinding on the cutting tool gripper is pushed ahead, and utilizes immediately in addition grinding of grinding attachment in the position of pushing ahead
Background technology
Ring flaker is for the production of the material of wood chip and so on, with for the manufacture of wood plank such as wood chip pressboard etc.Former timber is normally for example supplied with the wood chip form as bulk cargo.A kind of like this ring flaker has a cutter ring, a little cutter rings have several cutters be fixed on the cutting tool gripper/in.Cutting tool gripper for example is to be combined with a clamping plate that is connected through at least one fishbolt with this grip block by a grip block, and cutter utilizes pinching screw to be fixed between grip block and the clamping plate.But in category of the present invention, ring flaker is not only and is meaned a kind of chipper for the production of wood chip (wherein except the cutter ring of rotation, in case of necessity the inner pivot ring of configurable counter-rotating also), but also means the chipper for long timber.
Because the cutter of ring flaker is subject to very strong wearing and tearing, thus need the cutter of time interval reconditioning ring flaker in accordance with regulations, that is these cutters of reconditioning again.This point is to realize in the grinding process.For this reason, at first once the cutter ring is unloaded down from ring flaker.Each cutter need to be unloaded down from the cutter ring for reconditioning more in the past, used afterwards some devices, cutter is retained in the cutter ring.
For example at DE 43 16 514 C2(or corresponding EP 0 626 234 B1) in the used reconditioning of the cutter of the sort of ring flaker of the described type of known beginning or grinding method again, wherein each cutter still can remain in the cutter ring in again reconditioning process.The reconditioning of cutter is to realize by the grinding in its slow circumvolve situation in the state of cutter on being placed in knives rack, before the reconditioning whole cutters are in turn being unclamped in its fixed position, and advanced forward in its effective range according to an amount corresponding to the blade wearing and tearing.On this position of pushing ahead, each cutter is clamped again, advance for the required radial grinding of the desired blade overhang of the datum level of crossing tool holder in order to obtain subsequently, under the condition of the wear condition of considering this index plane, preprogram in addition.Employed grinding attachment refers to the grinding attachment of being furnished with emery wheel, and this emery wheel is through a drive motor utilization band transmission and driven.This emery wheel is fixed on the support, and this support utilizes a cross slide seat and can radially move with axial direction.For each cutter being advanced to by the determined cutter backstop of position calliper, used a knife combination mechanism, it is placed on the toolframe.This knife combination mechanism at first has a screw rod, unclamps fishbolt and fishbolt is tightened in tool holder again being used for, and to have a cutter push rod, to be used for each wood shavings cutter of single propelling.In addition, also disposed a pressure head, this pressure head is guaranteed the fixing of the cutter holding plate that unclamped in each cutter progradation, and all instruments operate according to the preprogram pneumatic mode.
A kind of comparable method is disclosed in EP 0 875 338 B1.The cutter ring, the cutter basket has several cutter bags or rather, and these cutter bags have separately a grip block, clamping plate, one and are in cutter and a fishbolt and a scuff panel between this two.When cutter no longer has required acutance, just must utilize an adjusting device that whole cutter basket is taken out from chipper.Then, a grinding attachment is incorporated in the inner chamber that is surrounded by the cutter basket.At this grinding attachment is so located, so that each emery wheel is aimed at a cutter to be ground.For this reason, grinding attachment has a plurality of emery wheels.
At last, can be from DE 695 01 961 T2(or corresponding EP 0 775 043 B1) see a kind of clamping system for the chipper cutter, this chipper design growth wood-planing sheet machine.The surface of clamp mechanism and/or clamper can have a kind of waveform profiles, this surface with waveform profiles can be out of shape so that when tightening fishbolt with a predetermined power described surface with basically uniformly clamping force act on the cutting mechanism.
Known ring flaker has proved it is reliable basically in actual use.But, the again reconditioning of cutter is very bothersome all the time.-theme of the present invention also is this.
Summary of the invention
Task of the present invention is to provide a kind of as the described the sort of method of beginning, and the method can realize a kind of smooth and good reconditioning and particularly again reconditioning of cutter of ring flaker simply.
In order to solve above-mentioned task, the present invention carries out a kind of particularly again reconditioning operation of cutter of ring flaker according to the method so that in the situation of not unclamping clamp mechanism with cutting tool gripper in/on cutter push ahead.If cutting tool gripper comprises the clamping plate that at least one grip block links to each other with this grip block with at least one fishbolt of process, cutter is fixed between grip block and the clamping plate, then the present invention's suggestion: in the situation of not unclamping fishbolt cutter is pushed ahead.
At this, the present invention is from following unexpected understanding: the cutter of ring flaker can utilize suitable mechanism to push ahead in order to realize again reconditioning simply, and the clamp mechanism on must the loosening cutter clamper.Therefore, the diverse suggestion of proposition of the present invention and known method: abandon to be in clamped condition for the cutter of again reconditioning and to push ahead by desired degree the unclamping of anchor clamps.Like this, just can abandon the sort of bothersome the unclamping to fishbolt that is accompanied by corresponding equipment needed thereby expense, thus can cost efficient ground and realize rapidly the again reconditioning of cutter.
At this, that cutter preferably utilizes is a kind of (machinery) propulsion plant especially preferably utilizes a kind of in check propulsion plant to push ahead.This this push ahead preferably can be continuously and from but pushing ground realize on compression type ground in other words, at this moment continuously or roughly continuously with certain propulsive force vertically being applied on the cutter along cutter.Surprisingly, the processing by this push-press type can overcome high clamping force, and cutter is advanced in the desired position.For this reason, propelling driving mechanism electronic or pneumatic or that surge can utilize propulsive element to be pressed onto on the cutter from behind.In addition, cutter also can adopt pulse mode or impact mode to push ahead, and for example uses propulsion plant that a kind of pulsating or impact type drive or work.A kind of like this propulsion plant of impact type is suitable for that also cutter itself is overcome high clamping force and pushes ahead in the situation of not unclamping clamp mechanism with meeting the requirements.This propulsion plant by pulsating or impact type driving for example can be equipped with a beater mechanism, as we all know shock machine or electric hammer.This propulsion plant can by pneumatic or driving, direct into high propulsive force in the cutter so as to overcoming clamping with surging.In addition or replenish a bit, also can adopt for example spiro driving device of Vidacare corp, special in the situation of continuous operation.
In the field of the invention, in check propulsion plant refers in particular to such an extent that be, propulsive force is not with manual mode, but mechanically, mode in accordance with regulations for example applies with the power of regulation and/or at the official hour interval.Say in principle, have such possibility, namely also can utilize measuring technique to monitor pushing ahead of realizing.But not absolute demand.
According to a preferred development of the present invention, proposed following setting: the cutter that is in the position of being pushed ahead is ground until predetermined overhang.At this, the present invention recognizes: be not that absolute demand just goes to realize an accurate overhang in the process that advances cutter.Would rather along with after advancing by to the corresponding grinding of cutter to realize desired overhang, so as to abandoning accurate location before.Even in the situation of very high clamping force, therefore also can abandon unclamping of clamp mechanism, but also especially why so do, be because need in the process of pushing ahead, just not go to defend tenaciously accurately overhang within the scope of the invention.
Preferably with the cutter ring after ring flaker is unloaded down, each cutter is carried out again reconditioning.This way is particularly suitable for the ring flaker for wood chip or analog, has also settled for example lead ring of reverse rotation of rotation in the cutter ring on this class ring flaker, and this lead ring takes wood chip in the scope of cutter to through centrifugal force.Within the scope of the invention, ring flaker also is the ring flaker for long timber wood shavings, in the long timber of this ring flaker is fed to flaking chamber in the cutter ring, and the lead ring of rotation is not set at there.
By the preferred specific embodiment, the cutter ring after chipper is unloaded down, just can be realized the again reconditioning of cutter in principle in cutter ring one " standing " directed situation, the cutter ring for example stands to land and is fixed in the suitable clamper accordingly.But cutter is preferably pushed ahead in the horizontal locational situation and in addition grinding being in.On this horizontal position, also high propulsive force can be applied, distortion or other interference of cutter ring need not be worried.At this, preferably the cutter ring is fixed on the horizontal position, for example use a suitable fixture for this reason.Have in addition following advantage in horizontal locational this processing: grinding attachment can be incorporated into from above in the cutter ring, thereby Grinding grits or grinding dust are discharged downwards simply.At this preferably in field of the present invention, can be to realize processing for example utilizing a kind of abrasive belt milling drum to process in the Dry Grinding process.So cooling agent of required usefulness in the time of in the situation that adopts this preferred specific embodiment, just can abandoning adopting wet grinding.
In addition, the present invention also proposes following setting: in the process of grinding and/or after grinding, the overhang of cutter is measured.This suits especially, when what reach as previously described, and in advance to advance carrying out accurate the measurement, but when when subsequently grinding, setting desirable overhang.This measurement must not utilize the particular measurement device of directly cutter being processed to carry out certainly, and preferably indirectly realize measurement to the cutter overhang by the suitable control to grinding attachment, for this reason, with radially so degree ground reach in grinding process of grinding attachment, so that adjustablely make desirable cutter overhang.
Content of the present invention also relates to a kind of device, is used for according to the sort of method of addressing the cutter of ring flaker being carried out particularly again reconditioning of reconditioning.This device comprises at least one propulsion plant, be used for pushing ahead in the cutting tool gripper/on cutter, and it is pushed to grinding attachment to realize the grinding to cutter.This device preferably has pushing ram or advances drift, and this device is characterised in that: propulsion plant is designed to and can pushes ahead cutter in the situation of not unclamping described clamp mechanism.Can refer to a kind of propulsion plant of continuous operation at this propulsion plant, perhaps also can refer to the propulsion plant of a kind of pulsating or impact type work.Grinding attachment is preferably designed to the abrasive belt grinding attachment, and it is preferably without cooling agent work.This propulsion plant can be equipped with a push-press type electronic, surge or pneumatic driving mechanism.Also the impact type driving mechanism can be set in addition.This driving mechanism acts on pushing ram or advances drift, and the latter acts on again cutter.

Fig. 3 to 6 expression is in the locational processing unit (plant) 11 of different operating.Its background is such fact: cutter ring 2 is to unload down from ring flaker with the state that " standing " arranges, then is to realize what processing was processed with the state that " horizontal " arranges at processing unit (plant) 11.Process in order to carry out simply this processing, turntable 13 and grinding attachment 12 are placed on the panoramic table 24, this panoramic table 24 can be fixed on the frame 14 pivotally around a horizontal axis 29, is put into so as to cutter ring 2 is inclined from a removed position with horizontal axis in the Working position with vertical axis.Structure and the working method of being furnished with this device of panoramic table can be drawn by comparative observation Fig. 3 to 6, and Fig. 6 uses processing unit (plant) 11 together with the cutter ring 2 that is in the horizontal Working position, utilize grinding attachment 12 to carry out grinding in this position.
At first with the cutter ring from unloading down by ring flaker shown in Figure 1, and utilize the pole 32 shown in the there it released from ring flaker.For example can utilize independent (not shown) to transport carriage from there the cutter ring is sent to processing unit (plant) 11.
Fig. 3 represents at first to be furnished with the processing unit (plant) of the panoramic table 24 of flatly settling, and the upper slitter ring not yet is installed.From this first operating position, at first processing unit (plant) is converted to the second station shown in Fig. 4 and puts, panoramic table is vertically to settle at this.On this operating position, cutter ring 2 can be accepted by unshowned carriage or the similarity piece of transporting now.For this reason, processing unit (plant) has two poles 31 in frame 14, and these two poles can be sailed into and roll away from, but thereby along continuous straight runs travel, so the cutter ring that can accept standing and can travel towards panoramic table 24.This situation can draw from the comparative observation Figure 4 and 5.Therefore cutter ring 2 is transferred in the processing unit (plant) 11 with the state that is standing, and then is fixed on the turntable 13.For this reason, turntable 13 has a plurality of retaining elements 30.After cutter ring 2 is fixed on the turntable 13, just can utilize rotary motion mechanism 25 that panoramic table 24 is turned round around horizontal axis 29, thereby make panoramic table 24 be transferred to horizontal level from vertical position, and whereby with the cutter ring from the position transfer stood to horizontal position, be vertically-oriented at the axis of this position upper slitter ring.This point can be found out from comparative observation Fig. 5 and 6.Therefore Fig. 6 illustrates processing unit (plant) 11 together with the cutter ring 2 that is positioned on the Working position, is in the horizontal layout and has vertically-oriented axis A at this Working position upper slitter ring.
At this particularly importantly: grinding attachment 12 is positioned on the panoramic table 24, but can be in axial direction and radially (for the axis A that is fixed on the cutter ring on the turntable) move with respect to turntable 13.Therefore, after cutter ring 2 is in the position on turntable 13 shown in Figure 6, grinding attachment 12 just in axial direction y fall, thereby it is extend in the cutter ring 2.The grinding of cutter 6 preferably is achieved around grinding attachment 12 rotations by cutter ring 2 when grinding attachment 12 operation lentamente.By grinding attachment 12 radially x with respect to the location of cutter ring 2 grinding is controlled.In an illustrated embodiment, be so to realize above-mentioned purpose by following measure from design: at slide 15 of panoramic table 24 configurations, thereby this slide 15 can with respect to machine frame movement and can with respect to panoramic table radially x move, therefore and can be positioned.Therefore, in the present embodiment, some linear guides 16 have been disposed for this reason.Be fixed wtih a clamping device 17 that is used for grinding attachment at slide 15, and this clamping device puts 17, and still in axial direction y is mobile at slide 15.This point means: clamping device 17(grinding attachment 12 also is fixed on this clamping device) can lifting.For this reason, between slide 15 and clamping device 17, disposed vertically-oriented linear guide 18.For turntable 13 has disposed a rotary drive mechanism that only schematically illustrates 19.Grinding attachment 12 is designed to the abrasive belt grinding attachment.It has for the grinding and driving mechanism 21 that is used for driving grinding belt 20.Grinding attachment 12, or rather, its clamping device 17 utilizes a lift drive mechanism 22 and removable at slide 15, for example can carry out lifting.In addition a configurable transmission that only schematically illustrates or feed drive unit 23, grinding attachment 12 or slide 15 utilize this transmission or feed drive unit just in axial direction x move.Can find out in addition: panoramic table 24 utilizes a rotary motion mechanism 25 just can turn round around axis of rotation 29.
In addition, also can find out from accompanying drawing: be fixed wtih a cutter propulsion plant 26 at panoramic table 24, this cutter propulsion plant has a plurality of cutter propulsion elements 27.Utilize these for example to can be used as the propulsion element 27 of push rod design, each cutter of cutter ring is passed forward by desirable degree.If cutter utilized propulsion plant 26 by to a certain degree passing forward before grinding, then was favourable.For this reason, propulsion plant 26 has two and attaches troops to a unit in the propelling driving mechanism 28 of push rod 27.As if these push rods pass the groove that always will arrange from the tool holder back, so they act on cutter from the cutter back side.In this favourable fact be: propulsion plant 26 is that (but can regulate in case of necessity) is positioned on the panoramic table regularly.Layout by setting fixed to one another is fixed on panoramic table take the fixing point 30 that is used for the cutter ring and propulsion plant 26 as the opposing party so turntable is a side, thereby so that their relative position can not change, when panoramic table 24 turns round, can not change especially.
According to the present invention, during propulsion plant 26 work, do not want the clamp mechanism of loosening cutter, thereby do not unclamp fishbolt.Therefore, cutter can utilize propulsion element 27 not advanced through its driving mechanism 28 with not unclamping clamp mechanism.In addition, the cutter ring can utilize rotary drive mechanism and be placed in the definite position, and advances a single cutter.Subsequently, the cutter ring can continue to be rotated by a definite angle, so next cutter is pushed into.Preferably at first with whole cutters by to a certain degree being advanced.When the rotating knife ring, utilize grinding attachment that whole cutters are carried out grinding immediately.In this interesting fact be: desirable cutter overhang can be in Grinding Process be achieved by suitable control grinding attachment and the particularly location by suitable control grinding attachment.Therefore, original propelling of cutter must not carried out an accurately position, and it is just enough cutter need only to be pushed ahead certain minimum degree.This is because desirable cutter overhang can obtain after only having grinding.
After grinding is finished, panoramic table 24 can be turned back in the position shown in Fig. 5 again, the cutter ring is taken out, and it is arranged on the ring flaker 1 again.
Except above-mentioned manner of execution, certainly also cutter individually can be pushed ahead successively and directly carries out within the scope of the invention reconditioning processing.According to this scheme, therefore do not utilize the cutter ring of rotation to carry out work, but under static cutter ring condition, carry out grinding.When cutter was ground with free angle, this scheme was only specially suitable.
