Abstract
A steel saw band (1) for a band saw machine comprises a band back (3) and a tooth blank having a plurality of teeth, at least the tooth blank (11) having a hard material coating. According to the invention, the coating comprises one or more of sub-groups IV, V or VI of the periodic table or aluminium or silicon and/or their nitrides, oxides, carbides, carbonitrides or borides and mixtures thereof. The method according to the invention is a vacuum coating method, such as PVD or paCVD.
Description
The present invention relates to the saw band that is used for the endless belt saw according to claim 1 preamble.In addition, the present invention relates to the method that is used for the production saw band according to claim 15 preamble.
The saw band of prior art is for example known from DE10202770A1.Being used for the described band sawing machine of DE2538718A1 for example and being used in particular for sawing those can not be with the large-scale workpiece of band saw processing.Although these saw bands are required great effort with respect to the material composition of improvement very much, they only design or are suitable for lower cutting speed and little feed rate and have very short blade life, i.e. their rusts and must often do corresponding replacing soon usually.
Be known that in addition the composition that cutter and band coating are provided is to improve abrasion resistance and to carry out corrosion protection.Usually adopt PVD (physical vapour deposition (PVD)) method or paCVD (plasma-assisted chemical vapour deposition) method or their combination for this purpose.
International open WO2005/014877A1 discloses the coating of steel bar in the roll processing, and wherein various hard material layers put on a side of bar, or put on the both sides of bar in subsequent processing steps, makes the bar that has cold bundle rigidity energy.Then, saw band can be made by this.
Shortcoming in this case is that coating represents from the side.Therefore, minimum bed thickness is used in the function face (back knife face and rake face) that the most directly is exposed to wearing and tearing, and maximum bed thickness is used in the side that is subjected to less load, thereby expensive clad material seldom uses.In addition, coating usually is used for cold bundle steel, and the latter is only hardened then, can be to layer/substrate in conjunction with having a negative impact.In other words, this cold bundle steel is difficult for applying after sclerosis, because conventional PVD handles the annealing temperature that far exceeds this material.Low temperature PVD handles the shortcoming have the layer that produces relatively poor bonding then, and this just in time is the major defect that exists in the situation of big load and grinding loss, as under the situation of sawing.Another shortcoming is handled by the roll that provides in the prior art and is caused.This technology does not allow to select the geometry of every kind of saw, for example because these bands can not twine, can not make pincers odontoid or can only make very poorly.Because the known bed thickness of prior art is much larger than 5 μ m, they are made expensive and can not have more any obvious improvement than the saw of uncoated, and because the trend that this layer peels off from the saw top when existing break-in, therefore, the advantage of coating no longer has any influence there.
Therefore, the purpose of this invention is to provide a kind of method that is used for the saw band of band sawing machine and is used to produce this saw band, make it might obtain more best performance, particularly better when processing metallic.In addition, produce and use the cost benefit of this saw band aspect all to be improved.
This purpose according to the present invention obtains by the feature that claim 1 provides.
According to saw band of the present invention, the coating according to the present invention of its tooth base makes the very long saw sword life-span become possibility at least, except making the longer life that saw band can use, allows to have bigger interval between the saw band of changing with mistake.
Another advantage of saw band is therefore can obtain higher cutting speed according to the present invention, perhaps can obtain higher feed speed.In addition, because the friction that reduces, coating can cause the very quiet and uniform running of saw band, and the feeding active force that consequently needs significantly reduces.
Be made up of HSS (high-speed steel) sill according to saw band of the present invention or corresponding band saw, hard layer applies on it by PVD or paCVD method.Because their higher heat endurances, it is desirable that high-speed steel is used to apply by PVD or paCVD processing, because the annealing temperature of these iron and steel is higher than 500 ℃ usually far away, thereby coating is possible in 500 ℃ of scopes, do not have any problem, this has guaranteed that comparing more much better layer/base material with K cryogenic treatment bonds.
In a preferred embodiment, behind the cutter bed thickness on the knife face greater than the bed thickness on the side of band saw tooth according to the present invention.
The layer that is particularly suitable for sawing coating is TiAlN and AlCrN layer, and they can for example produce on BAI1200 or RCS type industry application system.In addition at least in layer and the joint portion of wanting rapidoprint, the layer that the cutting ability aspect has been significantly increased is the combination of corresponding TiAlN, AlCrN, CrN and carbonitride and each layer of carbide, the multilayer or the gradient layer that for example have high-carbon content, be combined with metal or do not have metal DLC (diamond shape carbon) skin, and various silicon-containing layers, for example TiAlSiN, AlCrSiN and Si content are with respect to the corresponding carbonitride of whole tenor between 1 to 12 atomic percent.
Particularly suitable in addition layer system also comprises other hard material, for example one or more secondary group metallic element IV, V or VI (transition metal) in the periodic table, or aluminium or silicon, and their compound.Particularly, for example known TiN, VN or TiSiN or these nitride of SiN, these carbide of for example TiCN, VCN or carbonitride, boride, for example Al
2O
3, (AlCr)
2O
3These oxides and for example boron nitride, these corresponding nonmetallic mixtures of carbon oxynitride (carbooxinitrides) constitute the item that preparative layer is considered with listed metal.The layer of multilayer system and specific formation bonding and transition can help the processing of certain material.
The coating of nitrogen sill has been proved to be advantageous particularly for saw sword life-span and cutting speed and feed speed.In this favourable improvement, coating can comprise TiN, TiCN, TiAlN and/or AlCrN.All these materials also can be used as alloy or mixture is used here.
The another coating that is very suitable for application in practice can comprise as outer field WC/C, because this containing metal DLC layer system has good especially running-in performance, for example first cuts the layer smoothness in the circulation.Particularly as supporting layer, aforesaid system becomes the item of consideration.
In favourable development of the present invention, if coating has the thickness of 2-3 μ m, this will advantageously cause very quiet, the uniform operation of saw band, and not have obstruction or the similar problem that occurs when sawing workpiece under the bigger situation of coating thickness.Certainly, bed thickness also depend on tooth distribution, profile of tooth, want the material of material processed and coating itself, consequently different because of situation, also might adopt bigger bed thickness.
In order to optimize cutting ability, must correctly set correct bed thickness according to coating saw of the present invention.At this on the one hand, be surprised to find in the test, for example between 0.5 to 3 μ m, particularly the thinner layer between 0.7 to 2 μ m will be approximately 4 μ m or the thicker better cutting of thick-layer generation result than bed thickness.The latter only can compare little improvement of acquisition or basic not improvement than the band of uncoated aspect the cutting performance.
In another improvement of the present invention, available is that the tooth base is made up of HSSE.In coating according to the present invention together, this base material that is used for the tooth base causes anti abrasive especially saw band.
In the prior art, the saw of uncoated adopts the anterior angle geometry of α=0 ° to be used for simple sawing operation usually, and for example saw contains the workpiece (for example cast iron) of high-carbon content or the workpiece of small bore or thin-walled section and pipe.Here, the saw of the coating of anterior angle geometry α=0 ° can be particularly advantageous for sawing hard material, shear steel for example, and X38CrMoV5-1 for example, material number 1.2343, hardness is up to HB
30=235.This has special advantage, has big anterior angle and may also have the easier and cost of the geometry of crooked knife face more to produce in the lowland because this saw band geometry is comparable.Therefore, might not add coating and produce with low production cost and to be used for hard sawing operation or to saw the band of those big solid geometry sizes, described physical dimension is diameter particularly.In addition, also might test the geometry of tooth with negative rake, thereby between between-5 ° to+5 °, preferably the preceding angular region between-2 ° to 3 ° becomes the consideration object that has the hard saw that applies saw blade.
On the other hand, under the soft material situation of unusual effectively lubricating, VA stainless steel for example, X6Cr17 for example, material number 1.4016, hardness is up to HB
30=185, might obtain optimum with the acute angle profile of tooth of anterior angle α=10 °.Similar results can obtain in the scope of α=10 ° ± 3 °.
Might obtain the further improvement in the various application by the angle of the angle of β=1 and 5 of inclination flank face °, preferred β=2 to 3 °.
This purpose obtains by means of the method that the feature by claim 15 reflects.
In favourable improvement, if the material that forms coating by PVD or paCVD method under 450-550 ℃ temperature, preferably approximately apply under 500 to 550 ℃ the temperature, can obtain very good result with the method that is easy to implement according to coating saw band of the present invention.
In addition, availablely be, at least the tooth base before coating applies by the wiping deburring.As its substitute mode, the tooth base also can be subjected to hammering to remove burr before coating applies at least.This burr prevents that from the removing method of tooth base burr from coming off follow-up saw band is used, this coming off can produce the uncoated surface of saw band.
In the favourable improvement of this method, have coating iff the tooth base that upwards arrives the transition region adjacent with the band back, this can reduce production cost according to saw band of the present invention by saving coating material.This can not cause any reduction according to the quality of saw band of the present invention, because the band back of uncoated does not have the cutting function.For this purpose, for example the segment saw band might be combined into heap, they are for example wrapped in together with known reel retainer.Particularly, if the tooth base is made up of the material different with the band back, the back will be favourable if the tooth base is welded in band.
In addition, available is that saw band is welded in a ring after the coating.Like this, the immediately use of saw band in band sawing machine becomes possibility.
In the favourable improvement of the method according to this invention, if saw band is enclosed in the structure of shape such as coil, therefore spiral twines and is fixed in coating process in this form before coating, thereby the tooth base all points to identical direction, then can obtain saw band and very easily handle in applying device.For this method, this process also causes significant cost to reduce, because bigger saw band length can apply simultaneously.
According to the present invention, the saw band that a large amount of spirals twine is installed on the retainer and coating in a collection of.
In the accompanying drawing:
Fig. 1 has shown a tooth;
Fig. 2 has shown the details of saw band;
Fig. 3 has shown the tooth of uncoated and the section of coated tooth; And
Fig. 4 has shown applying device;
Fig. 5 to Fig. 9 has shown the chart of using according to sawing that saw band of the present invention is done test.
Fig. 1 has shown the exemplary details of the tooth 2 of the saw band 1 that has hump portion 3, and this tooth has the rake face that anterior angle is α, back knife face 5 and the side 7 that relief angle is β.
Saw band can form closed loop and be installed on the band sawing machine with known mode own.The direction of the cutting speed of saw band 1 is by the arrow indication that is expressed as " v " among Fig. 1.But this saw band level or vertically be used in the band sawing machine to ground.According to type of service, workpiece is towards band sawing machine 1 motion or reverse motions.
The details that has shown saw band 1 among Fig. 2.Here can see that saw band 1 has band back 10, saw band 1 guides thereon in not shown but known mode own in band sawing machine, and this external tooth base 11 has a plurality of teeth 2.Band back 11 preferably is made up of simple relatively " soft " steel, and tooth base 11 is made up of high-speed steel simultaneously, preferably HSSE.The use of simpler steel makes the suppleness of cost savings and saw band 1 increase for band back 10.Welding method is preferred for tooth base 11 is connected in band back 10.
For the special blade life that increases saw band 1, preferably also increase cutting speed, perhaps also increase feed speed, tooth base 11 has the coating that increases wearability at least.The coating of can't see in the accompanying drawing can for example comprise above-mentioned material or be made up of a kind of like this material.Coating also helps to reduce the cutting force of saw band 1.
Fig. 3 chart shown uncoated or with the tooth 2 ' of tradition stratum coating and use tooth 2 according to layer coating according to the present invention " at the cutaway view after using after a while.With dashed lines 6 expressions respectively of the top of original tooth or geometry.The tooth of uncoated demonstrates most advanced and sophisticated 6 ' to have bigger wearing and tearing and most advanced and sophisticated 6 ' rounding occurs after the cutting of same number.On the other hand, the tooth 2 of coating " demonstrate its top 6 " littler wearing and tearing, even and after coating has all ground, also do not have or rounding seldom occurs.This has very big advantage, owing to therefore the material guiding that is roughly guaranteed by most advanced and sophisticated 6 limit sword is maintained, even straight cutting also might realize when saw band heavy wear, simultaneously, band with big fillet tooth 2 ' demonstrates strong operation distortion trend, and this will increase is refused and/or ratio that material expends.
Fig. 4 has shown applying device 12 very schematically to express, and the production method that is used for the above-mentioned saw band 1 of band sawing machine realizes with it.With this applying device 12, the coating of the wearability of above-mentioned increase saw band 1 puts on tooth base 11 at least.Though not shown, the device 12 that preferred shape is the vacuum coated device comprises the necessary device of coating, as the splash target, along the evaporator crucible or the arc source (also can be their combination) of its electric operating means setting; And gas feeding and control device, for example be used for separating oxycompound or nitrogenate layer; Produce the vavuum pump of the essential pressure condition of operation PVD or paCVD method, and heater, measuring instrument and other process auxiliary drive.Such device is the device that is used for coating tool and parts in this area.
Under this situation, for coating saw band 1, a winding-structure as coil 8 is introduced applying device 7, it is suspended on the retainer 9 that is provided at the there.In this case, coil 8 can have the diameter up to 50cm, and it makes the total length of saw band 1 that 100m be arranged.Preferably, only upwards arrive the tooth base 6 of the transition region adjacent with band back 10, the tooth base 6 that promptly roughly upwards arrives the respective teeth gap has coating, thereby saves coating material.After coating, saw band 1 is from installing 12 rings that take out and can be welded in a not shown manner as shown in Figure 1.
Come off in the follow-up use of saw band 1 for fear of the burr that may be present on the tooth 2, this coming off brings uncoated areas can for the surface of saw band 1, thereby significantly reduce its wearability, in this case, the pressure that tooth base 11 usefulness are lower at least carries out wiping or hammering was removed burr before applying at coating.After the processing, corresponding tooth 5 has minor radius but not burr.When wiping, can adopt circulation brush, the saw band 1 of wiping on the coil 8.
Example:
Fig. 5 has most clearly shown the advantage according to saw band of the present invention.91.45 the 100Cr6 of * 14.3mm pipe, material number 1.3505 is processed in the cutting speed of 120m/min with the TiAlN coating that has about 1 to 2 μ m (BalinitFuturaNano, FNl handles) and the saw band of 0 ° of anterior angle.For the band of uncoated, the cutting speed that adopts the producer to recommend, i.e. 60m/min.Curve has shown the clipping time that depends on cutting quantity.Top curve has shown the value of uncoated band, and following curve has shown the value that applies band.300 workpiece are 5 hours with the whole clipping times that apply band.300 workpiece are 8 hours 24 minutes with whole clipping times of uncoated band.After 300 cuttings, applied half that be with each clipping time that has been lower than the uncoated band clipping time of cutting.
Fig. 6 has shown the saw band of the TiAlN coating that is coated with about 1 to 2 μ m on the shear steel of the different geometries of 80 * 80mm, X38CrMoV5-1, material number 1.2343 (BalinitFuturaNano is as figure) has been carried out two sawings tests.Cutting speed is 90m/min, cutting pressure 16 crust, feed speed 4.Difference between two bands only is present in the geometry of tooth, the more accurate anterior angle that is.Here find, fully surprisingly, have littler anterior angle promptly the saw band of 0 ° of anterior angle (curve of band diamond indicia is positioned at the bottom) clearly be better than the i.e. 10 ° of anterior angles (curves of band rectangle marked of the sharper anterior angle of band, be positioned at the middle part) saw band, this is opposite with the experience that applies saw band.
In the contrast test shown here, only " 10 ° of bands " of uncoated imposed the cutting speed of half, be 45m/min (according to producer's recommendation), other aspects are identical with above-mentioned condition, have 1/3rd back rusts of the saw band of 0 ° of anterior angle, have saw band rust after first half of cutting of 10 ° of anterior angles in cutting for the first time.This test is therefore only continuous with " 10 ° of bands " (curve of band triangular marker is positioned at the top).Certainly, used cutting for the third time, about 18 minutes of clipping time, and how much identical bands that apply need about 10 minutes clipping time, " 0 ° of band " of coating only needs about 6 minutes clipping time.
Fig. 7 has shown the contrast of the clipping time of coating with dissimilar tooth form and uncoated saw band.The heat treatable steel C45 of sawing solid, material number 1.0503, d=100mm in this case.The sawing parameter that has applied band is following to be set respectively.First result is shown by the post among Fig. 71.
Cutting speed 120m/min
If the band of uncoated is operated with identical parameter, this cutting becomes known distortion, i.e. cutting does not form straight line, and causes being refused.Therefore, the band of uncoated has to operate with corresponding low cutting speed and pressure; The post 4 of Fig. 7 consequently:
Cutting speed 75m/min
Therefore this had both allowed the band of 0 ° of anterior angle also to allow band with 10 ° of anterior angles, to reduce clipping time of about 50%, as the coating result, thereby might operate with higher cutting speed and pressure for the first time, adopt selected cutting parameter simultaneously, only possible is to obtain plane cutting with " 0 ° of saw band ".In other words, under " the 10 ° of bands " situation that applies with uncoated, there is the deviation of maximum 1mm in the convexity on cutting surface from cutting planes, and this will cause workpiece or be refused or heavily processing.
Fig. 8 and 9 has shown the sawing test result of saw blade under coating and uncoated form that has with the different geometries (Class1-3) of 0 °/10 ° of anterior angles.Workpiece among Fig. 8 is a stainless steel, X6Cr17, material number 1.4016.Cutting width is d=102mm not, cutting speed 120m/min, feed pressure 6.0.In Fig. 9, the depth of cut of heat treatable steel 42CrMo4, material number 1.7225 usefulness d=90mm, cutting speed and 4.4 feed pressures of 90m/min.In all cases, it is tangible having applied the advantage that saw band surmounts the uncoated saw band.
In softer stainless steel, optimum Cutting result obtains with the saw blade of coating of 10 ° of anterior angles.Yet in harder heat treatable steel, optimum obtains with the band of coating of 0 ° of anterior angle, and this is more startling, produces the poorest result because have the uncoated band of this anterior angle.
Another sawing test is carried out the heat treatable steel/cold bundle steel 42CrMo4V of solid, its material number 1.7225, d=300mm, cutting speed 50m/min, cutting pressure 16 crust, feed speed 3 is determined uncoated saw band and the saw sword life-span that applies saw band that has 0 ° of anterior angle and total cutting area with 16 ° of anterior angles.In this case, the uncoated band wore and tore after 6 hours, and total quantity is 21 to cut, and always cutting area is 1.48m
2With the band that has applied, might within its 8 hours useful 53 minute life-spans, obtain 31 and cut and 2.19m
2The cutting area, this corresponding to the cutting number of times increase and only be lower than total cutting area of 50%.
In addition, in long-time sawing test, the 16MnCr5 tubing of diameter 91mm, wall thickness 16mm, material number 1.7131 (HB140 to 207) is subjected to sawing at this moment, it is found that and having under the uncoated saw band situation of 10 ° of anterior angles, after 500 to 600 cuttings, cutting grinds off this angle 1mm on diameter.In other words, with saw band identical but uncoated, 900 to 1200 cuttings can obtain and can not observe band and grind this angle.This is very wondrous, even because the saw band of coating when they terminate and still possess this angle during rust at its service life.Therefore, for example the sawing operation is very possible whole night automatically realizes.
