上記解決手段による発明の効果を、後述する実施形態の参照符号を付して説明すると、請求項1に係る発明によれば、ロール素材5に軸方向の深孔6を穿設し、深孔6に耐食性及び耐摩耗性の良好な合金粉末7を充填してカプセル9を形成し、このカプセル9をHIP処理することによりロール素材5の深孔6に合金粉末のHIP層12を形成した後に、ロール素材5をHIP層12の一部が外周部に表れるよう円筒状に切削加工すると共に、ロール素材5の外周部とHIP層12の間に切欠溝3を削成し、この切欠溝3に臨むHIP層12部分を仕上げ加工してノッチロール1のエッジ部4を形成するようにしたから、エッジ部材をロール本体部と別体に製作してボルト止めしていた従来の製造方法に比べ、ノッチロール1の製造が簡単容易となって、その製造コストを安くできると共に、耐食性及び耐摩耗性の良好な合金粉末7をHIP処理した硬質のHIP層12によって、キズや摩耗、腐食に強く、耐久性に優れた高精度のエッジ部4を形成することができる。 The effect of the invention by the above means will be described with reference numerals of the embodiments described later. According to the invention according to claim 1, the deep hole 6 in the axial direction is formed in the roll material 5, and the deep hole is formed. 6 is filled with an alloy powder 7 having good corrosion resistance and wear resistance to form a capsule 9, and the capsule 9 is subjected to HIP treatment to form a HIP layer 12 of the alloy powder in the deep hole 6 of the roll material 5. The roll material 5 is cut into a cylindrical shape so that a part of the HIP layer 12 appears on the outer periphery, and the notch groove 3 is formed between the outer periphery of the roll material 5 and the HIP layer 12. Since the edge part 4 of the notch roll 1 is formed by finishing the HIP layer 12 facing the surface, the edge member is manufactured separately from the roll body part and bolted to the conventional manufacturing method. Easy manufacture of notch roll 1 The manufacturing cost can be reduced, and the hard HIP layer 12 obtained by HIP-treating the alloy powder 7 having good corrosion resistance and wear resistance is highly resistant to scratches, wear and corrosion, and has high durability. The edge part 4 can be formed.

また、この製造方法によれば、HIP層12はミリ単位の十分な厚さで存在するので、エッジ部4が摩耗しても、その補修は、研削加工したり鏡面加工するだけでよく、従ってエッジ部4が機能を発揮する間は繰り返し使用することができる。又、エッジ部4は、マイクロスコープ測定で1ミクロン単位まで自由に削成することができ、その表面粗度はRy0.1ミクロンまでに仕上げることができる。Further, according to this manufacturing method, since the HIP layer 12 exists in a sufficient thickness of millimeter units, even if the edge portion 4 is worn, the repair may be performed only by grinding or mirror finishing. It can be used repeatedly while the edge part 4 exhibits its function. Further, the edge portion 4 can be freely cut to the 1 micron unit by microscope measurement, and the surface roughness can be finished to Ry 0.1 micron.

一方、請求項2に係る発明のように、ロール素材5が丸棒材からなる場合は、深孔6の孔開け加工は容易であるが、ロール重量が重くなるため、小型のノッチロールを製造する場合に適している。On the other hand, when the roll material 5 is made of a round bar as in the invention according to claim 2, the drilling of the deep hole 6 is easy, but the roll weight becomes heavy, so a small notch roll is manufactured. Suitable for you.

また、請求項3に係る発明のように、ロール素材5が厚肉のパイプ材(中空材)5bからなる場合は、深孔6の孔開け加工は困難であるが、中空状であるためロール重量の軽減化を図ることができ、大型のノッチロール1を製造する場合に適している。Further, when the roll material 5 is made of a thick pipe material (hollow material) 5b as in the invention according to claim 3, the deep hole 6 is difficult to be drilled, but the roll material 5 is hollow and thus has a roll shape. The weight can be reduced, which is suitable for manufacturing a large notch roll 1.

請求項4に係る発明によれば、上記製造方法によって、ロール素材5の外周面に耐食性及び耐摩耗性の良好な合金粉末7がHIP(熱間等方圧加圧)処理された合金粉末のHIP層12を形成し、このHIP層12にノッチロールのエッジ部4が一体形成されてなるため、エッジ部材をロール本体部と別体に製作してボルト止めしていた従来の製造方法に比べ、ノッチロール1の製造が簡単容易となって、その製造コストを安くできると共に、耐食性及び耐摩耗性の良好な合金粉末7をHIP処理した硬質のHIP層12によって、キズや摩耗、腐食に強く、耐久性に優れた高精度のエッジ部4を形成することができる。According to the invention of claim 4, the alloy powder obtained by subjecting the outer peripheral surface of the roll material 5 to the HIP (hot isostatic pressing) treatment of the alloy powder 7 having good corrosion resistance and wear resistance by the manufacturing method described above. Since the HIP layer 12 is formed and the edge portion 4 of the notch roll is integrally formed on the HIP layer 12, the edge member is manufactured separately from the roll main body portion and is bolted to the conventional manufacturing method. The notch roll 1 can be manufactured easily and easily, its manufacturing cost can be reduced, and the hard HIP layer 12 obtained by HIP treatment of the alloy powder 7 having good corrosion resistance and wear resistance is resistant to scratches, wear and corrosion. Thus, it is possible to form the highly accurate edge portion 4 having excellent durability.

請求項5に係る発明によれば、ロール素材5の外周部に複数個のエッジ部4が形成されてなるため、エッジ部4が摩耗した場合には、ノッチロール1を取り替えることなく、そのノッチロール1を取付台に対し回転させて他のエッジ部4をセットすることにより、そのまま使用することができるから、より経済的に使用することができる。According to the fifth aspect of the present invention, since the plurality of edge portions 4 are formed on the outer peripheral portion of the roll material 5, when the edge portion 4 is worn, the notch roll 1 is not replaced and the notch is replaced. By rotating the roll 1 with respect to the mounting base and setting the other edge portion 4, it can be used as it is, so that it can be used more economically.

FIG. 1 (a) is a front view showing a notch roll manufactured by the method of the present invention, and FIG. 1 (b) is an AA line of (a). 1 is a notch roll, and bosses 2 and 2 for fixing the notch roll to a machine base (not shown) of a coating apparatus are provided at both ends of the notch roll 1. Is attached. Further, the notch roll 1 is formed with two notch grooves 3 parallel to the axial direction of the notch roll 1 at intervals of 180 ° in the circumferential direction, and each notch groove 3 is provided with an edge portion 4. Yes.

図2は上記ノッチロール1の使用状態を示しており、このノッチロール1は固定ロールであって、回転するバックアップロール10との間で一方向に走行する基材ウェブ20の一面に塗布された高粘度の塗工液30を、エッジ部4、正確にはそのエッジ面4aでならして膜厚を均一にするようになっている。   FIG. 2 shows the state of use of the notch roll 1, which is a fixed roll and applied to one surface of the base web 20 that travels in one direction with the rotating backup roll 10. The high-viscosity coating liquid 30 is leveled at the edge portion 4, more precisely the edge surface 4a, so that the film thickness is uniform.

上記ノッチロール1を製造する方法について、図3〜図8を参照しながら、以下に説明する。   A method for manufacturing the notch roll 1 will be described below with reference to FIGS.

先ず、ロール素材5として、ステンレス系材料からなる所定径及び所定長さの円筒形状のムク材(丸棒材)5aを使用し、このロール素材5に、図3の(a) ,(b) に示すように、軸心から一定半径にある周辺側に所定径の例えば2つの深孔6,6を、ロール素材5の一端から他端側へ軸方向に沿って穿設する。母材であるロール素材5を形成するステンレス系材料としては、例えば、SUS329J(オーステナイト/フェライトの2相系ステンレス)等を使用する。   First, as the roll material 5, a cylindrical mug material (round bar material) 5a made of a stainless steel material and having a predetermined diameter and a predetermined length is used, and the roll material 5 has (a) and (b) in FIG. As shown in FIG. 5, two deep holes 6 and 6 having a predetermined diameter are formed along the axial direction from one end of the roll material 5 to the other end side on the peripheral side having a constant radius from the axial center. For example, SUS329J (austenite / ferrite two-phase stainless steel) or the like is used as the stainless steel material forming the roll material 5 as the base material.

それから、図4の(a) ,(b) に示すように、ロール素材5の各深孔6に夫々耐食性及び耐摩耗性の良好な合金粉末7を充填し、各深孔6の開口端部を塞ぎ板8により塞いで密閉することにより、カプセル9を形成する。合金粉末7は、ニッケル基合金粉末、コバルト基合金粉末、タングステンカーバイト含有合金粉末等を使用する。尚、塞ぎ板8は、ロール素材5の端面に当て付けて適宜溶接することにより取り付ける。   Then, as shown in FIGS. 4 (a) and 4 (b), each deep hole 6 of the roll material 5 is filled with an alloy powder 7 having good corrosion resistance and wear resistance, and the open end of each deep hole 6 is filled. The capsule 9 is formed by closing and sealing with a closing plate 8. As the alloy powder 7, a nickel-base alloy powder, a cobalt-base alloy powder, a tungsten carbide-containing alloy powder, or the like is used. The closing plate 8 is attached by being applied to the end surface of the roll material 5 and appropriately welding.

上記のようにして形成したカプセル9を、図5の(a) に示すように、HIP(熱間等方圧加圧)装置11内に入れて、HIP処理を施すことにより、ロール素材5の各深孔6内で前記合金粉末7が焼結され、深孔6の壁面に拡散されて一体に接合された円柱状HIP層12を形成する(図5の(b) 参照)。このHIP層12は、硬度HRC58前後の硬質の合金である。   As shown in FIG. 5 (a), the capsule 9 formed as described above is placed in a HIP (hot isostatic pressing) device 11 and subjected to HIP treatment, whereby the roll material 5 The alloy powder 7 is sintered in each deep hole 6 to be diffused on the wall surface of the deep hole 6 to form a cylindrical HIP layer 12 that is integrally joined (see FIG. 5B). The HIP layer 12 is a hard alloy having a hardness of around HRC58.

こうして各深孔6にこれと同径の円柱状HIP層12を一体に形成したロール素材5を、図5の(b) 及び(c) に示すように、HIP層12の一部が外周部に表れるように旋盤等によって所要径の円筒状に切削加工し、そしてロール素材5の外周部とHIP層12との間にロール素材5の軸方向に平行な切欠溝3をフライス盤や平削り盤等によって削成し、そして更に図5の(d) に示すように、この切欠溝3に臨むHIP層12の内端面12aを平面研削盤により平面研削加工し、またその外周部分12bを円筒研削盤により円筒研削加工更に鏡面加工して所望の仕上げ加工することにより、硬質のエッジ部4を形成する。鏡面加工には、ダイヤモンド砥石を使用する。   In this way, the roll material 5 in which the cylindrical HIP layer 12 having the same diameter is integrally formed in each deep hole 6, as shown in FIGS. 5B and 5C, a part of the HIP layer 12 is an outer peripheral portion. As shown in FIG. 5, a lathe or the like cuts into a cylindrical shape having a required diameter, and a notch groove 3 parallel to the axial direction of the roll material 5 is formed between the outer peripheral portion of the roll material 5 and the HIP layer 12 in a milling machine or a planing machine. Then, as shown in FIG. 5 (d), the inner end surface 12a of the HIP layer 12 facing the notch groove 3 is surface ground by a surface grinder, and the outer peripheral portion 12b is cylindrically ground. A hard edge portion 4 is formed by cylindrical grinding with a disk and mirror finishing to obtain a desired finish. A diamond grindstone is used for mirror finishing.

上述したようなノッチロール1の製造方法によれば、図3、図4に示すように、ロール素材5にその軸方向に平行な深孔6を穿設し、この深孔6に耐食性及び耐摩耗性の良好な合金粉末7を充填してカプセル9を形成し、図5に示すように、このカプセル9をHIP装置11によってHIP処理することによってロール素材5の深孔6に合金粉末のHIP層12を形成した後に、ロール素材5をHIP層12の一部が外周部に表れるように円筒状に切削加工すると共に、ロール素材5の外周部とHIP層12の間に切欠溝3を削成し、この切欠溝3に臨むHIP層12部分を仕上げ加工してノッチロール1のエッジ部4を形成するようにしたから、エッジ部材をロール本体部と別体に製作してボルト止めしていた従来の製造方法に比べると、ノッチロール1の製造が容易となって、その製造コストを安くできると共に、耐食性及び耐摩耗性の良好な合金粉末7をHIP処理した硬質のHIP層12によって、キズや摩耗、腐食に強く、耐久性に優れた高精度のエッジ部4を形成することができる。   According to the method of manufacturing the notch roll 1 as described above, as shown in FIGS. 3 and 4, a deep hole 6 parallel to the axial direction is formed in the roll material 5, and the deep hole 6 has corrosion resistance and resistance. A capsule 9 is formed by filling the alloy powder 7 with good wearability, and the capsule 9 is subjected to HIP treatment by the HIP device 11 as shown in FIG. After forming the layer 12, the roll material 5 is cut into a cylindrical shape so that a part of the HIP layer 12 appears on the outer periphery, and the notch groove 3 is cut between the outer periphery of the roll material 5 and the HIP layer 12. Since the edge portion 4 of the notch roll 1 is formed by finishing the HIP layer 12 portion facing the notch groove 3, the edge member is manufactured separately from the roll body portion and bolted. Compared to the conventional manufacturing method The roll roll 1 can be easily manufactured and its manufacturing cost can be reduced, and the hard HIP layer 12 obtained by HIP treatment of the alloy powder 7 having excellent corrosion resistance and wear resistance is resistant to scratches, wear and corrosion, and is durable. It is possible to form the highly accurate edge portion 4 excellent in the above.

また、この製造方法では、HIP層12はミリ単位の十分な厚さで存在することから、エッジ部4が摩耗しても、その補修は研削加工したり鏡面加工するだけでよく、そのためエッジ部4が機能を発揮する間は何回も繰り返し使用することができる。又、エッジ部4は、マイクロスコープ測定で1ミクロン単位まで自由に削成することができ、その表面粗度はRy0.1ミクロンまでに仕上げることができる。   Further, in this manufacturing method, since the HIP layer 12 is present in a sufficient thickness of millimeter units, even if the edge portion 4 is worn, the repair may be performed only by grinding or mirror finishing. It can be used repeatedly many times while 4 functions. Further, the edge portion 4 can be freely cut to the 1 micron unit by microscope measurement, and the surface roughness can be finished to Ry 0.1 micron.

図1〜図5に示すノッチロール1の製造方法では、カプセル9の形成にあたり、ロール素材5に深孔6を二つ穿設し、これらの深孔6,6に夫々合金粉末7を充填して、カプセル9(図4)を形成しているが、図6の(a) ,(b) は、カプセル9を形成するにあたって、ロール素材5には深孔6を一つだけ穿設し、これに合金粉末7を充填して、カプセル(図示せず)を形成する場合を示し、(c) はその場合のカプセル9をHIP処理した後、機械加工して製造されたノッチロール1を示す。   In the manufacturing method of the notch roll 1 shown in FIGS. 1 to 5, when forming the capsule 9, two deep holes 6 are formed in the roll material 5, and these deep holes 6 and 6 are filled with the alloy powder 7 respectively. The capsule 9 (FIG. 4) is formed. In FIGS. 6 (a) and 6 (b), when forming the capsule 9, only one deep hole 6 is formed in the roll material 5. This shows a case in which the alloy powder 7 is filled to form a capsule (not shown), and (c) shows the notch roll 1 manufactured by subjecting the capsule 9 in that case to HIP treatment and machining. .

ロール素材5に形成する深孔6は必要に応じて1つでもよいし二つ以上複数でもよい。深孔6を複数穿設すれば、エッジ部4が複数設けられるから、エッジ部4が摩耗した場合には、ノッチロール1を取り替えることなく、そのノッチロール1を取付台に対し回転させて他のエッジ部4をセットすることにより、そのまま使用することができる。   The number of deep holes 6 formed in the roll material 5 may be one or more than two as required. If a plurality of deep holes 6 are formed, a plurality of edge portions 4 are provided. Therefore, when the edge portion 4 is worn, the notch roll 1 is rotated with respect to the mounting base without replacing the notch roll 1. Can be used as they are.

図7の(a) はロール素材5に深孔6を複数穿設した場合であるが、これらの深孔6,6に夫々合金粉末7を充填してカプセル9(図4)を形成し、HIP処理した後、HIP層12には塗工に適した任意形状の機械加工を施して、必要とされる所望のエッジ部4を形成することができる。   FIG. 7 (a) shows a case where a plurality of deep holes 6 are formed in the roll material 5. Each of these deep holes 6 and 6 is filled with an alloy powder 7 to form a capsule 9 (FIG. 4). After the HIP treatment, the HIP layer 12 can be machined in an arbitrary shape suitable for coating to form a desired edge portion 4 as required.

図1〜図7に示した実施形態のノッチロール1は、ロール素材5を丸棒材(ムク材)5aからなるものとし、この丸棒材5aからなるロール素材5に深孔6を穿設しているが、このような丸棒材からなるロール素材5は、パイプ材(中空材)からなるものに比べて、深孔6の孔開け加工は容易であるが、ロール重量が重くなることから、小型のノッチロール1を製造する場合に適している。   The notch roll 1 according to the embodiment shown in FIGS. 1 to 7 has a roll material 5 made of a round bar material (a waste material) 5a, and a deep hole 6 is formed in the roll material 5 made of this round bar material 5a. However, the roll material 5 made of such a round bar material is easier to drill deep holes 6 than the pipe material (hollow material), but the roll weight is heavy. Therefore, it is suitable for manufacturing a small notch roll 1.

図8の(a) ,(b) はロール素材5が厚肉パイプ材(中空材)5bからなる場合を示している。このようにロール素材5が厚肉のパイプ材(中空材)5bからなる場合は、深孔6の孔開け加工が困難となるが、中空状であるためロール重量の軽減化を図ることができ、従って大型のノッチロール1を製造する場合に適している。   FIGS. 8A and 8B show a case where the roll material 5 is made of a thick pipe material (hollow material) 5b. As described above, when the roll material 5 is made of a thick pipe material (hollow material) 5b, it is difficult to drill the deep holes 6, but the roll weight can be reduced because of the hollow shape. Therefore, it is suitable for manufacturing a large notch roll 1.
