The below illustrates example 1 of the present invention according to Fig. 1-10.
As shown in Figure 1, 2, a kind of saw blade 10, it is identical with annular saw or side milling cutter discoideus that integral body is.Saw blade 10 comprises the annular saw body 12 that is formed by discoideus gold and a plurality of cutters tooth 14 of being located at annular saw body 12 peripheries.The center of saw blade 10, the embedded hole 16 of the circle that form to connect at direction of principal axis.As shown in Figure 3, Figure 4, the thickness U1 of annular saw body decides according to the bendability of itself, and when the outer diameter D 1 of saw blade 10 was 400mm, the thickness U1 of annular saw body can be 2.5-8mm, such as 3.2mm.
Cutter tooth installation portion 20, as shown in Figure 2, there is cutter tooth installed surface 24 at interior all sides place of apex 22, and periphery inclined plane 26 is arranged in the periphery.Periphery inclined plane 26 is in along between the apex 22 of the cutter tooth installation portion 20 of the direction of rotation Fn the place ahead one side cutter tooth installation portion 20 adjacent with rear one side.And periphery inclined plane 26 is by forming at extended the second periphery inclined plane 26b of radially inner side from extended the first periphery inclined plane 26a of the radially inner side of annular saw body 12 with the inclination angle larger than the first periphery inclined plane 26a.Between the second periphery inclined plane 26b and the cutter tooth installed surface 24, form the arc surface 28 that falls at the inner radial place.Form the stepped vacancy that to settle cutter tooth 14 on the cutter tooth installed surface 24.Form groove 29 between each cutter tooth installation portion 20.Do not show among Fig. 2, even the shockproof groove of incision intralamellar part is arranged or have the peripheral part from groove 29 beginnings towards direction inside, footpath to have various shockproof grooves also to be fine at annular saw body 12.
The shape of saw blade 10 profoundly forms from steel plate, for example profoundly forms by the laser cutting machined.Further, cutter tooth installed surface 24 is to form by the smart cutting of the instrument of for example milling cutter.
As shown in Figure 2, cutter tooth 14 is fixed on cutter tooth installed surface 24 places, for example fixes with solder flux.Cutter tooth 14 is comprised of rimmer knife tooth 30 and short sword tooth 40.Rimmer knife tooth, short sword tooth 40 are rectangular-shaped by the hard knife head that consists of such as superhard alloy, ceramic-metallic hard material, the high rigidity cutter head that perhaps consists of such as the adamantine high rigidity sintered body of many crystallizations.Rimmer knife tooth 30 has front edged surface 32 as shown in Figure 2, side 34, side cutting blade 36, periphery escape face 38, periphery cutting blade 39.Front edged surface 32 is relative with the periphery inclined plane 26 in direction of rotation Fn the place ahead.Side 34 is the state of intersecting vertically with thickness direction.Side cutting blade 36 is in the position that front edged surface 32 and side 34 intersect.Periphery cutting blade 39 is in the position that front edged surface 32 and periphery escape face 38 intersect.Rimmer knife tooth 30 as Fig. 2, shown in Figure 3, in the time of radially outstanding to the outside from annular saw body 12 beginning, be that the central shaft C direction of saw blade is outstanding to the thickness direction of annular saw body 12 also.Shown in Fig. 3,4 like that, the thick T1 scope of the sword of rimmer knife tooth is at 2.6-10mm, when being 400mm such as outer diameter D 1, the thick T1 of the sword of rimmer knife tooth is 4.4mm.The basic comprising of short sword tooth 40 is the same with rimmer knife tooth 30.Such as Fig. 2, shown in 5,6 like that, have front edged surface 42, side 44, side cutting blade 46, periphery escape face 48 and periphery cutting blade 49.The thick T2 scope of the sword of short sword tooth is at 2.6-10mm, and when external diameter was 400mm, the thick T2 of the sword of short sword tooth was 4.4mm.
Rimmer knife tooth 30, as shown in Figure 4, side 34 begins towards inner radial from the position of periphery cutting blade 39, forms the centripetal angle R1 in side take radius J1 as benchmark, has the centripetal amount S1 in side.Rimmer knife tooth 30 has more than or equal to the centripetal line length L1 in the side of 4mm, and preferably scope is 4-12mm, and what so the ripple quantity of machined material W section can be controlled in the process of processing is less, and the price of saw blade 10 is cheaper.When the not enough 4mm of the centripetal line length L1 in the side of rimmer knife tooth 30, the ripple quantity of above-mentioned section is difficult to diminish; When the centripetal line length L1 in side when 12mm is above, saw blade 10 just is difficult to obtain cheap price.According to on, for obtaining less section ripple quantity and comparatively cheap price, the best scope of the centripetal line length L1 in side is at 4-8mm.
Below double radial line J1, the centripetal angle R1 in side and the centripetal line length L1 in side specifically describe.
As shown in Figure 4, the central shaft C of periphery cutting blade 39 and saw blade can observe by imaginary plane H1.Article two, radius J1 is included among the imaginary plane H1, and for being begun to point to respectively the central shaft C of saw blade by the direction of principal axis two ends of periphery cutting blade 39, and the illusion line that intersects vertically with the central shaft C of saw blade.The centripetal angle R1 in side, be two sides 34 of rimmer knife tooth 30 respectively take radius J1 as benchmark, begin towards inner radial the angle of the inclination that has by the direction of principal axis two ends of periphery cutting blade 39.The centripetal line length L1 in side is that the side 34 of rimmer knife tooth 30 is from the length along radius J1 direction of periphery cutting blade 39 34 radial inner end to the side.
Rimmer knife tooth 30 has 0 °-1.0 ° the centripetal angle R1 in side as shown in Figure 4.When the centripetal angle R1 in the side of rimmer knife tooth 30 less than 0 °, be that angle value is when being negative value, when rotating shaft 100 as shown in Figure 7 and ring flange contact-making surface 105 vibration-generating, cutting resistance will become large or burnt possibility is arranged with respect to the ripple glaze X of machined material W shown in Figure 8.When the angle of the centripetal angle R1 in the side of rimmer knife tooth 30 during greater than 1.0 °, centripetal angle R1 is excessive in the side, and like this ripple glaze X of machined material W will diminish with the contact area of side 34, and the ripple glaze of the section of machined material W may just can not diminish.In view of more than, the angular range of the centripetal angle R1 in the side of rimmer knife tooth 30 wishes at 0.2 °-0.8 °, but preferably at 0.3 °-0.7 °.
Here, the radius J2 of short sword tooth 40, the radius J1 of the centripetal angle R2 in side and the centripetal line length L2 in side and above-mentioned rimmer knife tooth 30, the centripetal angle R1 in side and the centripetal line length L1 in side are same definition.In other words, as shown in Figure 6, radius J2 includes the central shaft C of periphery cutting blade 49 and saw blade.Can see by imaginary plane H2, begin the imaginary line that has respectively one to be orthogonal to the central shaft C of saw blade from the direction of principal axis two ends of periphery cutting blade 49, i.e. radius J2.The centripetal angle R2 in side is take radius J2 as benchmark, and the side 44 of short sword tooth 40 begins respectively a angle of inclination towards inner radial from the arbitrary end of the direction of principal axis of periphery cutting blade 49.The centripetal line length L2 in side is take radius J2 as benchmark, and the side 44 of short sword tooth 40 begins length to inner radial from axial arbitrary end of periphery cutting blade 49.Above-mentioned periphery cutting blade 49 is the tip of short sword tooth 40.
As shown in Figure 1, the quantity of rimmer knife tooth 30 accounts for the 2-15% of the sum of rimmer knife tooth 30 and short sword tooth 40, and will be more than 2.The quantity of rimmer knife tooth 30 discontented cutter tooth 14 sums 2% the time, the ripple quantity of the machined material W section by 30 processing of rimmer knife tooth will be difficult to diminish.Also have, if the quantity of rimmer knife tooth 30 greater than cutter tooth 14 sums 15% the time, the Costco Wholesale of saw blade 10 just is difficult to reduce.The cutter tooth 14 of saw blade 10, by 6 rimmer knife teeth and 66 short sword teeth, totally 72 teeth consist of.Each rimmer knife tooth 30, the configuration that central angle can not wait at interval, but the preferred center angle becomes uniformly-spaced configuration.Central angle becomes in the situation of uniformly-spaced configuration, in process, the ripple glaze X that is embodied in the machined material W on the machined surface during with rotating shaft 100 contacted ring flange contact-making surface 105 vibration just can not be that it is less that the situation that the ripple glaze X of machined material W just can dispose than the central angle unequal interval of each rimmer knife tooth 30 becomes everywhere.
Next, when utilizing saw blade 10 to cut machined material W, rimmer knife tooth 30 roles describe.What Fig. 8 showed is, is accompanied by the vibration of rotating shaft 100 and ring flange contact-making surface 105, when the state of vibration length occurring in the cutter tooth side, and the ideograph of the ripple glaze X that produces during cutting machined material W.As shown in Figure 8, therefore saw blade 10 cutter tooth side vibration length A will occur in the cutter tooth side at the rotating shaft 100 and ring flange dish contact-making surface 105 places meeting vibration-generating of processing unit (plant).Here, if hypothesis saw blade 10 all is to be made of short sword tooth 40, the periphery cutting blade 49 of short sword tooth 40, the track with ripple glaze X cuts with respect to machined material W when saw blade 10 rotation.In other words, the saw blade that only consists of with short sword tooth 40 is accompanied by cutter tooth side vibration length A and can produces ripple glaze X.This ripple glaze X has the height with cutter tooth side vibration length A equal extent, and this just is defined as the ripple glaze amount of machined material W section.In this example, saw blade 10 has short sword tooth 40 and rimmer knife tooth 30.Therefore, saw blade 10 has the rimmer knife tooth 30 of the centripetal line length L1 in side in rotation, so the ripple glaze amount of cutting machined material W section with smooth ripple glaze X will diminish.
The shape of ripple glaze X, shown in Fig. 7,8 like that, the speed of the sending into F of the rotational speed N of saw blade 10, machined material W, and the vibration of rotating shaft 100 and ring flange contact-making surface 105 vibrate the three elements of length A for affect saw blade 10 cutter tooth sides.As mentioned above, for machined material W, the periphery cutting blade 49 of short sword tooth 40 whenever rotates a circle at saw blade 10, a Cutting trajectory approximate with ripple glaze X will occur.Therefore, the distance Y (mm) of the ripple glaze X that saw blade whenever rotates a circle and is sent into speed F(m/min) and the relation of the rotational speed N (rpm) of saw blade 10, satisfy " Y=(F * 1000)/N ".Also have, the maximum height of ripple glaze X is the same high with cutter tooth side vibration length A.At this moment, the distance Y of the ripple glaze X that saw blade whenever rotates a circle is the base, take cutter tooth side vibration length A as height, consists of triangle as shown in Figure 8.Be the angle γ of ripple glaze with this leg-of-mutton base angle viewpoint definition, satisfy " γ=2A/Y ".According to more than, the centripetal angle R1 in the side of rimmer knife tooth 30, less than the angle γ of ripple glaze, so the ripple glaze amount of machined material W section also can diminish.
According to more than, the relation of the centripetal angle R1 in side of the angle γ of reference wave Slippage and rimmer knife tooth 30, during saw blade 10 work, the preferred 1000-5000rpm of rotational speed N.
Also have, the relation of the centripetal angle R1 in side of the angle γ of reference wave Slippage and rimmer knife tooth 30, the speed of the sending into F of machined material W is 5-120m/min.The ripple glaze quantitative change of machined material W section is little when sending into the not enough 5m/min of speed F, but process velocity can be slack-off.Send into speed F greater than 120m/min the time, the ripple glaze amount of machined material W section will become large.Further with reference to the ripple glaze amount of process velocity and machined material W section, the preferred 20-80m/min of the speed of sending into F of machined material W.
Next, concern between the ripple glaze amount to the centripetal line length L1 in the side of rimmer knife tooth 30 and machined material W section and describe.The cutter tooth side vibration length A of setting saw blade 10 is 0.3mm, the centripetal angle R1 in the side of rimmer knife tooth 30 is 1 °, the situation that to choose respectively the centripetal line length L1 in side be 1mm, 2mm, 4mm, 8mm and 12mm, the ripple glaze amount of measuring machined material W section is with the trend of sending into speed F and changing.Measurement result as shown in Figure 9.
Next, the cutter tooth side vibration length A of setting saw blade 10 is 0.3mm, the centripetal angle R1 in the side of rimmer knife tooth 30 is 0.5 °, the situation that to choose respectively the centripetal line length L1 in side be 1mm, 2mm, 4mm, 8mm and 12mm, measure the ripple glaze amount of machined material W section with the trend of sending into speed F variation, its result as shown in figure 10.
Such as Fig. 9, shown in 10, when the centripetal line length L1 in side is 1mm, 2mm, send into speed F in the scope of 0-20m/min, the ripple glaze amount of machined material W section can significantly become large.Because among the present invention more than the preferred 20m/min of the speed of sending into F of machined material W, thus saw blade 10 the centripetal line length L1 in side to be set as 1mm, 2mm be unaccommodated.On the other hand, centripetal line length L1 is 4mm when the side of saw blade 10, and the centripetal angle R1 in side is 1 °, and with the speed of the sending into F of 30m/min machined material W is added man-hour, and the ripple glaze amount of machined material W section can rise to more than the 0.08mm rapidly.Also have, the centripetal angle R1 in side is 0.5 °, and with the speed of the sending into F of 25m/min machined material W is added man-hour, and the ripple glaze amount of machined material W section can rise to more than the 0.04mm rapidly.Therefore, when rimmer knife tooth 30 selects 20m/min above at the speed of the sending into F of machined material W, just can obtain the above centripetal line length L1 in side of gratifying 4mm.Also have, the use centripetal angle R1 in side is that 0.5 ° the rimmer knife tooth 30 ratio use centripetal angle R1 in side are 1.0 ° rimmer knife tooth 30, and the ripple glaze amount of machined material W section is less.
Specific embodiment 1 in the above-mentioned example 1:
Rimmer knife tooth 30, the quantity of rimmer knife tooth 30 are 6, the thick T1:4.4mm of sword of rimmer knife tooth, the centripetal line length L1:8mm in side, the centripetal angle R1:1 in side °.Each rimmer knife tooth 30 is configured to the style such as interval such as central angle such as grade that central angle is respectively 60 degree.
The cutter tooth side vibration length A of the saw blade 10 of embodiment 1 is set as respectively 0.22mm and 0.35mm, use 10 couples of machined material W of this saw blade to process test, relation between the ripple glaze amount of mensuration cutter tooth side vibration length A and machined material W section, condition determination is as follows:
Machined material W is that two thickness are the MDF(medium density fibre board (MDF) that is fitted with the melamine plate of 15mm) overlapping forming, so gross thickness reaches 30mm.The MDF that is fitted with the melamine plate mixes the timber small pieces first and is hot pressed into MDF with binding agent, form in MDF surface heat densification amine thin plate again.
Processing unit (plant), the speed of the sending into F:39m/min of the rotational speed N of the diameter of ring flange 103: 120mm, saw blade 10: 3600rpm, machined material W.
Measurement result represents measured value with black circle as shown in figure 11.As shown in Figure 11, cutter tooth side vibration length A is as being 0.22mm, and the ripple glaze amount of machined material W section is 0.03mm.Cutter tooth side vibration length A is 0.35mm, and the ripple glaze amount of machined material W section will become 0.08mm.
For embodiment 1, following 7 comparative examples are set:

As shown in figure 11, in the comparative example 1, the ripple glaze amount of machined material W section is 0.08mm.In the comparative example 2, the ripple glaze amount of machined material W section is 0.06mm.In the comparative example 3, the ripple glaze amount of machined material W section is 0.24mm.In the comparative example 4, the ripple glaze amount of machined material W section is 0.28mm.According to more than, just be equal to the full short sword tooth 40 that is when all the centripetal line length in side of cutter tooth 14 is 2mm, because the vibration of rotating shaft 100 and ring flange contact-making surface 105, along with the change of cutter tooth side vibration length A is large, the ripple glaze amount of machined material W section will become large.
As shown in figure 11, in the comparative example 5, the ripple glaze amount of machined material W section is 0.10mm.In the comparative example 6, the ripple glaze amount of machined material W section is 0.01mm.In the comparative example 7, the ripple glaze amount of machined material W section is 0.08mm.Among the comparative example 5-7, all the centripetal line length in side of cutter tooth 14 is more than 4mm, along with the vibration of rotating shaft 100 and ring flange contact-making surface 105, large even vibration length A in cutter tooth side becomes, little also or than comparative example 1 to 4 of the ripple glaze amount of machined material W section.But all cutter tooth 14 is the above rimmer knife tooth 30 of the centripetal line length 4mm in side, and saw blade 10 costs that consist of are not low.
On the other hand, the quantity of rimmer knife tooth 30 is 6 among the embodiment 1, accounts for the 2-15% of whole 72 cutters tooth, and the effect when at this moment the ripple glaze amount of machined material W section and saw blade 10 whole cutters tooth 14 adopt rimmer knife tooth 30 to consist of is close.In other words, be the 2-15% of saw blade 10 whole cutter tooth 14 quantity as long as the quantity of rimmer knife tooth 30 reaches, just can obtain unexpected effect.The saw blade 10 that consists of like this, the ripple glaze amount of machined material W section is significantly diminished and also price also cheap.
As mentioned above, the saw blade 10 of this example, even when rotating shaft 100 and ring flange contact-making surface 105 place vibration-generatings, it is very little that the ripple glaze amount of machined material W section also can become, and saw blade 10 prices are cheap.Although rimmer knife tooth 30, short sword tooth 40 is compared with short sword tooth 40 by forming such as the adamantine expensive material of many crystallizations, very expensive of rimmer knife tooth 30, but because the quantity of rimmer knife tooth 30 only accounts for the 2-15% of cutter tooth 14 sums, the saw blade 10 that therefore consists of still is dirt cheap.
Saw blade of the present invention is not limited only to above-mentioned example, can also be other following examples.
Example 2:
Only be with the difference of example 1: at rimmer knife tooth 30, the front edged surface of short sword tooth 40 arranges the inclination angle.Owing to set anterior angle face tilt angle, the ripple glaze amount of machined material W section will further diminish, and obtains very level and smooth section.Particularly along with the vibration of rotating shaft 100 with ring flange contact-making surface 105, cutter head side vibration length A also can also obtain desirable section when becoming large.
Example 3:
Only be with the difference of example 1: the periphery cutting blade 39 of rimmer knife tooth 30, the angle is ground in the periphery cutting blade 49 places design of short sword tooth 40.Because designed and ground the angle, the ripple glaze amount of machined material W section also can further diminish, and then also can obtain very level and smooth section.
Example 4:
Only be with the difference of example 1: as shown in figure 12, the rimmer knife tooth 30 of saw blade 10 arranges chamfering at the place, two ends of periphery cutting blade 39.As shown in figure 13, the short sword tooth 40 of saw blade 10 also arranges chamfering at the place, two ends of periphery cutting blade 49.
Above foundation desirable embodiment of the present invention is enlightenment, and by above-mentioned description, the related personnel can in the scope that does not depart from this invention technological thought, carry out various change and modification fully.The technical scope of this invention is not limited to the content on the specification, must determine technical scope according to the claim scope.
