Description

【0001】
【発明の属する技術分野】
本発明は金属線材の皮削りチッパー、特に、チタン又はチタン合金などの硬い金属線材の皮削りに使用して最適な皮削りチッパーに関する。
【0002】
【従来の技術】
金属線材の製造過程において、線材の表面に発生したきづ,細かい割れ,酸化物等を除去する目的で、金属線材の表面層を切削する皮削りが行われている。金属線材の表面層の皮削りを行う場合は、図3に示すように、図示しない供給ロールと巻取りロールとの間に矯正ロールを設け、この矯正ロールの後部側に設けた皮削りチッパー11内に前記供給ロールから繰り出された金属線材Aを導入し、該金属線材Aを前記巻取りロールで巻取って矢印P方向に引き抜くことによってその表面層Aaを刃先12で連続的に皮削りする。
【0003】
前記刃先12は、図4の拡大部分図に示すように、刃先構成部13の掬い面13aと刃先部14の掬い面14a、及び刃先構成部13の逃げ面13bと刃先部14の逃げ面14bとからそれぞれ構成されており、前記掬い面13a,14a及び逃げ面13b,14bにはそれぞれ掬い角θ1 ,θ2 及び逃げ角β1 ,β2 をもたせてある。
【0004】
ここで、掬い角θ1 ,θ2 をそれぞれ小さくすることは前記刃先12の刃先角が大きくなることを意味し、逆に掬い角θ1 ,θ2 をそれぞれ大きくすることは刃先12の刃先角が小さくなることを意味する。したがって、掬い角θ1 ,θ2 がそれぞれ所定角度より大きくなると、皮削りの際に掬い面13a,14aに切削屑Rが衝当してその排出が円滑に行われず、特に掬い面13aのクレータ摩耗が大きくなって短寿命となる。逆に掬い角θ1 ,θ2 がそれぞれ所定角度より大きすぎると刃先12が薄肉厚となり、刃先構成部13,刃先部14が欠け易くなってしまう。
【0005】
一方、逃げ角β1 ,β2 がそれぞれ所定角度より小さすぎると、刃先構成部13,刃先部14の摩耗に伴う二番当りが激しくなり、皮削りされた線材A2 の線送りが円滑に行われない。逆に逃げ角β1 ,β2 がそれぞれ所定角度より大きすぎると、皮削りされた線材A2 とのクリアランスが部分的に大きくなって短寿命となるとゝもに刃先12が薄肉厚となり、刃先構成部13,刃先部14が欠け易くなってしまうといった問題点がある。
【0006】
【発明が解決しようとする課題】
このような従来の問題点を解決するため、最適な刃先角,掬い角θ1 ,θ2 ,及び逃げ角β1 ,β2 について従来より種々研究開発がなされているが、チタン又はチタン合金からなる線材のように表面が高硬度の場合には、前記刃先角,掬い角θ1 ,θ2 及び逃げ角β1 ,β2 などの問題点の他に次のような問題点が未解決となっており、その解決策が望まれている。
【0007】
すなわち、チタン又はチタン合金などの硬い材料からなる線材Aの表面層Aaを、上記のような従来の皮削りチッパー11で皮削りした場合、皮削り後の線材A2 の表面肌にはリングマークが発生する。ここでリングマークとは線材円周に発生するリング状の模様のことであり、このリングマークが線材円周に発生するとその後の加工(冷間鍛造,異形加工等)でもその跡が残留し、外観上問題となっていた。
【0008】
本発明は上記のような従来の問題点を解決するために成されたもので、特にチタン又はチタン合金などの硬い金属線材を皮削りした場合にも線材円周にリングマークが発生しない皮削りチッパーを提供することを目的としたものである。
【0009】
【課題を解決するための手段】
前記の目的を達成するため、本願の第1発明は、金属線材の皮削りに使用するチッパーであって、該チッパーの刃先を半径0.03〜1.0mmの円弧面で形成したことを特徴とする金属線材の皮削りチッパーにある。これにより、皮削り時における刃先の軽微な振動(線材の長手方向の振動)が抑えられ、皮削り後の線材の表面肌にリングマークが発生するのを防止できる。
【0010】
また、前記目的を達成するための本願第2発明は、金属線材の皮削りに使用するチッパーであって、該チッパーの刃先を半径0.03〜1.0mmの円弧面で形成した刃先構成部とその後部に連続する刃先部とで構成するとゝもに、前記刃先構成部と刃先部の掬い角の角度差及び逃げ角の角度差をそれぞれ0°〜10°に形成したことを特徴とする金属線材の皮削りチッパーである。
【0011】
上記構成により、刃先構成部の掬い面とその後部に連続する刃先部の掬い面及び刃先構成部の逃げ面とその後部に連続する刃先部の逃げ面との接続部がそれぞれがほゞ直線的な平面で連続し、切削屑の排出及び切削線材の送りがスムーズに行われる。したがって、高速での連続した皮削りができるとゝもに、皮削り時における刃先の軽微な振動がより確実に抑えられ、皮削り後の線材の表面肌にリングマークが発生するのを防止できる。
【0012】
【発明の実施の形態】
以下、本発明を図1及び図2に示す実施形態により詳細に説明すると、図において、1は皮削りチッパーで、その刃先2は先端部の刃先構成部3とその後部に連続する刃先部4とで構成されており、前記刃先構成部3は後述する円弧面で形成されている。3aは前記刃先構成部3の掬い面,3bは同じく逃げ面、4aは前記刃先部4の掬い面,4bは同じく逃げ面であり、前記掬い面3a,4a及び逃げ面3b,4bにはそれぞれ掬い角θ’,
θ及び逃げ角β’,βをそれぞれもたせてある。
【0013】
そして、刃先2の先端部を構成する前記刃先構成部3は半径0.03〜1.0mmの円弧面で形成されており、これにより皮削りチッパー1で線材Aの皮削りを行う際に発生する刃先2の軽微な振動を抑制でき、皮削り後の線材A2 の表面肌にリングマークが発生するのを無くすことができる。詳述すると、皮削り後の線材A2 の表面肌にリングマークが発生するのは、切削時における刃先2の振動(特に線材長手方向の振動)によって形成されるものと考えられる。そこで、本発明では、刃先2の先端部を構成する前記刃先構成部3に丸みを施こすことにより、切削時における刃先2の振動の発生を抑制したものである。
【0014】
前記刃先構成部3の円弧面の大きさは皮削りする金属線材に対する皮削力によって定まる。すなわち、前記刃先構成部3の円弧面の半径が0.03mm未満では皮削力が大きすぎて滑らかな切削とはならず、皮削り時において刃先2に軽微な振動が発生し、その結果、表面肌にリングマークが発生する。逆に、刃先構成部3の円弧面の半径が1.00mmより大きいと皮削力が小さすぎ、皮削り効果が期待できないので、前記円弧面の半径を0.03〜1.0mmとした。
【0015】
また、前記刃先構成部3を所定半径の円弧面とすることによって、前記掬い面3aの掬い角θ’と掬い面4aの掬い角θとの角度差(θ−θ’)及び前記逃げ面3bの逃げ角β’と逃げ面4bの逃げ角βとの角度差(β−β’)をそれぞれ小さくすることができる。掬い面3aの掬い角θ’と掬い面4aの掬い角θとの角度差を小さくするということは掬い面3aの掬い角θ’を大きくすることができ、又逃げ面3bの逃げ角β’と逃げ面4bの逃げ角βとの角度差を小さくするということは逃げ面3bの逃げ角β’を小さくできることを意味する。
【0016】
したがって、刃先2を構成する前記刃先部4の掬い面4aが所定の傾斜角度からなる一定の傾斜面であっても、該刃先部4の先端に位置する前記刃先構成部3の掬い面3aと前記掬い面4aとの接続部はほゞ直線面で連続することになるとゝもに、前記刃先部4の逃げ面4bが所定の傾斜角度からなる一定の傾斜面で構成したものであっても、前記刃先構成部3の逃げ面3bと前記逃げ面4bとの接続部もほゞ直線面で連続することになる。
【0017】
すなわち、この種皮削りチッパーにおいて、前記掬い面4aの掬い角θが40〜50°,また前記逃げ面4bの逃げ角βが3〜10°が最も好ましいことが判ったが、刃先2の先端部を構成する前記刃先構成部3を半径0.03〜1.0mmの円弧面で形成した場合、その掬い面3aの掬い角θ’及び逃げ面3bの逃げ角β’を前記掬い面4aの掬い角θ及び逃げ面4bの逃げ角βとほゞ同じ大きさか或いはこれより少し小さく形成することは容易である。したがって、掬い角の角度差(θ−θ’)及び逃げ角の角度差(β−β’)をそれぞれ小さくすることができるが、実験の結果では、前記掬い角の角度差及び前記逃げ角の角度差がそれぞれ0°〜10°の場合が最も良好であった。
【0018】
その結果、刃先構成部3の掬い面3aとその後部に連続する刃先部4の掬い面4a及び刃先構成部3の逃げ面3bとその後部に連続する刃先部4の逃げ面4bとの接続部がそれぞれがほゞ直線的な平面で連続することになり、線材Aの表面層Aaを切削する際に発生する切削屑Rの排出及び切削材の線送りがスムーズになる。これにより、切削時における刃先2に発生する線材の長手方向の振動がより一層抑制されるとゝもに、掬い面3a,4aのクレータ摩耗が小さくなって長寿命となる。なお、刃先2の先端部を構成する前記刃先構成部3は半径0.03〜1.0mmの円弧面で形成したが、より好ましくは前記刃先構成部3の半径を0.05〜0.5mmとすることがよい。
【0019】
【実施例】
表1に、本発明に係る皮削りチッパーと比較例の皮削りチッパーとでそれぞれ切削した場合のリングマークの有無の実験例を示す。なお、この実験では、熱間圧延により形成した直径5.5mmの純チタン線材に熱処理を施し、80m/minの高速で超硬皮削チッパー内を通過させ、直径5.2mmに皮削加工した。
【0020】

【0021】
この結果は表1に示す通りであり、刃先に半径0.03〜1.0mmの円弧面を備えた本発明の皮削りチッパーでは線材の円周表面にリングマークが全く付かないか、あってもその後の冷間鍛造,異形加工等でその跡が残留しない程度のものであった。特に、刃先の半径が0.05〜0.5mmの範囲においては線材の円周表面にリングマークの発生が全くないことが判る。
【0022】
【発明の効果】
本発明に係る金属線材の皮削りチッパーは、上記のような構成であるから、切削屑の排出及び切削材の線送りがスムーズに行われ、皮削り時における刃先の軽微な振動が確実に抑えられる。したがって、皮削り後の線材の表面肌にリングマークのない高肌品質の線材を得ることができるとゝもに、高速での連続切削が可能となる、といった諸効果がある。

BACKGROUND OF THE INVENTION
The present invention relates to a chipping chipper for a metal wire, and more particularly to a chipping chipper that is optimal for use in the cutting of a hard metal wire such as titanium or a titanium alloy.
[0002]
[Prior art]
2. Description of the Related Art In the process of manufacturing a metal wire, cutting is performed to cut the surface layer of the metal wire for the purpose of removing cracks, fine cracks, oxides and the like generated on the surface of the wire. When the surface layer of the metal wire is cut, as shown in FIG. 3, a straightening roll is provided between a supply roll and a winding roll (not shown), and a skinning chipper 11 provided on the rear side of the straightening roll. The metal wire A fed from the supply roll is introduced therein, the metal wire A is taken up by the take-up roll and pulled in the direction of the arrow P, and the surface layer Aa is continuously cut with the cutting edge 12. .
[0003]
As shown in the enlarged partial view of FIG. 4, the cutting edge 12 includes a scooping surface 13 a of the cutting edge forming portion 13, a scooping surface 14 a of the cutting edge portion 14, and a clearance surface 13 b of the cutting edge configuration portion 13 and a clearance surface 14 b of the cutting edge portion 14. The scooping surfaces 13a, 14a and the clearance surfaces 13b, 14b are provided with scooping angles θ 1 , θ 2 and clearance angles β 1 , β 2 , respectively.
[0004]
Here, decreasing the scooping angles θ 1 and θ 2 means increasing the cutting edge angle of the cutting edge 12. Conversely, increasing the scooping angles θ 1 and θ 2 respectively increases the cutting edge angle of the cutting edge 12. Means smaller. Therefore, when the grooving angles θ 1 and θ 2 are larger than the predetermined angles, the cutting scraps R abut against the grooving surfaces 13a and 14a during cutting, and the discharge is not performed smoothly. The wear increases and the life is shortened. On the other hand, if the scooping angles θ 1 and θ 2 are too larger than the predetermined angles, the cutting edge 12 becomes thin and the cutting edge constituent part 13 and the cutting edge part 14 are likely to be chipped.
[0005]
On the other hand, if the clearance angles β 1 and β 2 are respectively smaller than the predetermined angles, the second contact due to wear of the blade edge portion 13 and the blade edge portion 14 becomes intense, and the wire feed of the shaved wire rod A 2 becomes smooth. Not done. On the other hand, if the clearance angles β 1 and β 2 are too larger than the predetermined angles, the clearance with the shaved wire A 2 is partially increased to shorten the service life. There exists a problem that the structure part 13 and the blade edge | tip part 14 will become easy to chip.
[0006]
[Problems to be solved by the invention]
In order to solve such conventional problems, various researches and developments have been made on the optimum cutting edge angle, rake angle θ 1 , θ 2 , and clearance angles β 1 , β 2. In the case where the surface has a high hardness as in the case of a wire rod, the following problems are unresolved in addition to the problems such as the cutting edge angles, the rake angles θ 1 and θ 2 and the clearance angles β 1 and β 2. The solution is desired.
[0007]
That is, when the surface layer Aa of the wire A made of a hard material such as titanium or a titanium alloy is cut with the conventional chipping chipper 11 as described above, a ring mark is formed on the surface skin of the wire A 2 after cutting. Occurs. Here, the ring mark is a ring-shaped pattern that occurs on the circumference of the wire, and when this ring mark occurs on the circumference of the wire, the trace remains in subsequent processing (cold forging, deforming, etc.) It was a problem in appearance.
[0008]
The present invention has been made to solve the above-described conventional problems, and in particular, when a hard metal wire such as titanium or a titanium alloy is cut, a ring mark is not generated on the circumference of the wire. The purpose is to provide a chipper.
[0009]
[Means for Solving the Problems]
In order to achieve the above object, the first invention of the present application is a chipper used for cutting a metal wire, wherein the tip of the chipper is formed by an arc surface having a radius of 0.03 to 1.0 mm. It is in the chipper chipping of the metal wire. Thereby, the slight vibration of the cutting edge (vibration in the longitudinal direction of the wire) at the time of cutting can be suppressed, and generation of a ring mark on the surface skin of the wire after cutting can be prevented.
[0010]
Further, the second invention of the present application for achieving the above object is a chipper for use in the cutting of a metal wire, wherein the tip of the chipper is formed by an arc surface having a radius of 0.03 to 1.0 mm. And a blade edge portion that is continuous with the rear portion, the angle difference between the cutting edge configuration portion and the blade edge portion and the angle difference between the clearance angles are each 0 ° to 10 °. It is a chipping chipper for metal wires.
[0011]
With the above configuration, the scooping surface of the cutting edge constituent part, the scooping surface of the cutting edge part continuing to the rear part thereof, and the connecting part between the flank face of the cutting edge constituent part and the flank face of the cutting edge part continuing to the rear part thereof are substantially linear. It is continuous on a flat surface, and cutting waste is discharged and cutting wire is fed smoothly. Therefore, if continuous cutting can be performed at high speed, slight vibration of the cutting edge during cutting can be more reliably suppressed, and ring marks can be prevented from being generated on the surface skin of the wire after cutting. .
[0012]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in detail with reference to the embodiment shown in FIG. 1 and FIG. 2. In the drawings, reference numeral 1 denotes a cutting chipper, and a cutting edge 2 thereof is a cutting edge constituent part 3 at the tip part and a cutting edge part 4 continuous to the rear part. The blade edge component 3 is formed by an arc surface described later. 3a is a scooping surface of the cutting edge component 3, 3b is also a clearance surface, 4a is a scooping surface of the cutting edge portion 4, 4b is also a clearance surface, and the scooping surfaces 3a, 4a and clearance surfaces 3b, 4b are respectively Ugly angle θ ',
θ and clearance angles β ′ and β are given respectively.
[0013]
And the said blade edge | tip structure part 3 which comprises the front-end | tip part of the blade edge | tip 2 is formed in the circular arc surface of radius 0.03-1.0mm, and it generate | occur | produces when cutting the wire A with the skin chipper 1 by this. The slight vibration of the cutting edge 2 can be suppressed, and generation of ring marks on the surface skin of the wire A 2 after cutting can be eliminated. More specifically, it is considered that the ring mark is generated on the surface skin of the wire A 2 after shaving is formed by vibration of the cutting edge 2 during cutting (particularly vibration in the longitudinal direction of the wire). Therefore, in the present invention, the cutting edge forming part 3 constituting the tip part of the cutting edge 2 is rounded to suppress the vibration of the cutting edge 2 during cutting.
[0014]
The size of the arc surface of the cutting edge constituent part 3 is determined by the cutting force with respect to the metal wire to be cut. That is, if the radius of the arcuate surface of the cutting edge component 3 is less than 0.03 mm, the cutting force is too large to achieve smooth cutting, and slight vibration is generated in the cutting edge 2 during cutting. Ring marks appear on the surface skin. On the other hand, if the radius of the arc surface of the blade edge component 3 is larger than 1.00 mm, the cutting force is too small to expect a cutting effect, so the radius of the arc surface is set to 0.03 to 1.0 mm.
[0015]
Further, by making the cutting edge constituting portion 3 an arc surface having a predetermined radius, the angle difference (θ−θ ′) between the scooping angle θ ′ of the scooping surface 3a and the scooping angle θ of the scooping surface 4a and the clearance surface 3b. The angle difference (β−β ′) between the clearance angle β ′ and the clearance angle β of the clearance surface 4b can be reduced. Reducing the angle difference between the creeping angle θ ′ of the scooping surface 3a and the scooping angle θ of the scooping surface 4a can increase the scooping angle θ ′ of the scooping surface 3a, and the clearance angle β ′ of the clearance surface 3b. Reducing the angle difference between the clearance surface 4b and the clearance angle 4b means that the clearance angle β 'of the clearance surface 3b can be decreased.
[0016]
Therefore, even if the scooping surface 4a of the cutting edge part 4 constituting the cutting edge 2 is a constant inclined surface having a predetermined inclination angle, the scooping surface 3a of the cutting edge constituent part 3 located at the tip of the cutting edge part 4 When the connecting portion with the scooping surface 4a is substantially continuous with a straight surface, the flank 4b of the blade edge portion 4 may be constituted by a constant inclined surface having a predetermined inclination angle. The connecting portion between the flank 3b of the blade edge component 3 and the flank 4b is also a substantially straight surface.
[0017]
In other words, in this seed-cutting chipper, it has been found that the scooping angle θ of the scooping surface 4a is most preferably 40 to 50 °, and the clearance angle β of the scissoring surface 4b is most preferably 3 to 10 °. Is formed with an arc surface having a radius of 0.03 to 1.0 mm, the scooping angle θ ′ of the scooping surface 3a and the scooping angle β ′ of the scooping surface 3b are scooping of the scooping surface 4a. It is easy to form the angle θ and the clearance angle β of the flank 4b approximately equal to or slightly smaller than the clearance angle β. Therefore, the angle difference (θ−θ ′) and the angle difference (β−β ′) of the crawl angle can be reduced, respectively. The best results were obtained when the angle difference was 0 ° to 10 °.
[0018]
As a result, the connecting portion of the scooping surface 3a of the cutting edge constituent portion 3 and the scooping surface 4a of the cutting edge portion 4 continuing to the rear portion thereof, and the flank 3b of the cutting edge constituent portion 3 and the flank 4b of the cutting edge portion 4 continuing to the rear portion thereof. Are continuous in a substantially linear plane, and the discharge of the cutting waste R generated when the surface layer Aa of the wire A is cut and the wire feed of the cutting material become smooth. Thereby, when the vibration in the longitudinal direction of the wire generated in the cutting edge 2 at the time of cutting is further suppressed, the crater wear of the scooping surfaces 3a and 4a is reduced, resulting in a long life. In addition, although the said blade edge | tip structure part 3 which comprises the front-end | tip part of the blade edge | tip 2 was formed in the circular arc surface of radius 0.03-1.0mm, More preferably, the radius of the said blade edge | tip structure part 3 is 0.05-0.5mm. It is good to do.
[0019]
【Example】
Table 1 shows an experimental example of the presence or absence of a ring mark when cut with the skin chipper according to the present invention and the skin chipper of the comparative example. In this experiment, a pure titanium wire with a diameter of 5.5 mm formed by hot rolling was heat treated, passed through a cemented carbide chipper at a high speed of 80 m / min, and cut to a diameter of 5.2 mm. .
[0020]
[Table 1]
Figure 0003772118
[0021]
This result is as shown in Table 1. In the chipping chipper of the present invention having a circular arc surface with a radius of 0.03 to 1.0 mm at the cutting edge, there is no ring mark on the circumferential surface of the wire. However, the trace was not left in the subsequent cold forging and deforming. In particular, it can be seen that no ring mark is generated on the circumferential surface of the wire when the radius of the blade edge is in the range of 0.05 to 0.5 mm.
[0022]
【The invention's effect】
Since the metal wire skinning chipper according to the present invention is configured as described above, the discharge of the cutting waste and the wire feeding of the cutting material are performed smoothly, and the slight vibration of the cutting edge during the cutting is surely suppressed. It is done. Therefore, there are various effects that, in addition to obtaining a high-skin quality wire without ring marks on the surface skin of the wire after cutting, continuous cutting at high speed is possible.
