Description
本発明は、溝付板の製造方法に関する。 The present invention relates to a method for manufacturing a grooved veneer.
Ｈ形鋼等の鋼材同士を、スプライスプレートを用いた高力ボルト摩擦接合によって接合することがある。この場合、スプライスプレートは両鋼材に沿って配置され、両鋼材に高力ボルトやナット等を用いて締結される。 Steel materials such as H-shaped steel may be joined by high-strength bolt friction welding using a splice plate. In this case, the splice plate is arranged along both steel materials, and is fastened to both steel materials using high-strength bolts, nuts, or the like.
このような高力ボルト摩擦接合による接合部は、高力ボルトに導入する軸力、スプライスプレートと鋼材の摩擦面のすべり係数、および摩擦面の数によってその耐力を確保する構成となっている。 Such a joint portion by frictional joining of high-strength bolts is configured to secure its resistance by the axial force introduced into the high-strength bolt, the slip coefficient of the friction surface between the splice plate and the steel material, and the number of friction surfaces.
そのため、スプライスプレートの鋼材に接する面に赤錆を発生させたり、ショットブラスト加工を施したりして所定のすべり係数（例えば日本建築学会編「建築工事標準仕様書JASS6」では0.45）を確保している。 Therefore, a predetermined slip coefficient (for example, 0.45 in "Building Construction Standard Specification JASS6" edited by Architectural Institute of Japan) is secured by generating red rust on the surface of the splice plate in contact with the steel material and performing shot blasting. ..
しかしながら、近年の鋼材の高張力化や大断面化の影響により、接合部に必要となる耐力も大きくなる傾向にある。そのために高力ボルト本数を増やして耐力を向上させることも可能であるが、コストや工数が増加する問題がある。 However, due to the recent increase in tension and large cross section of steel materials, the yield strength required for joints tends to increase. Therefore, it is possible to increase the number of high-strength bolts to improve the proof stress, but there is a problem that the cost and man-hours increase.
一方、摩擦面のすべり係数を向上させれば高力ボルトの本数の増加を抑えることができる。特許文献１、２には、すべり係数を向上させるため、略三角形状の凸部を所定ピッチで設けた溝付のスプライスプレートの例が記載されている。 On the other hand, if the slip coefficient of the friction surface is improved, the increase in the number of high-strength bolts can be suppressed. Patent Documents 1 and 2 describe an example of a grooved splice plate in which substantially triangular convex portions are provided at a predetermined pitch in order to improve the slip coefficient.
上記のような凸部を有するスプライスプレートは、略三角形状の刃を所定ピッチで配列したカッタを用いて金属板を切削することで製造できる。しかしながら、この刃の山や谷は製作精度の関係から完全な角とはなっておらず、丸みを帯びるのが通常である。上記の凸部の頂点はカッタの刃の谷に対応する形状となるため、凸部の頂点が角状になりにくく、高いすべり係数を得にくいという問題があった。 A splice plate having a convex portion as described above can be manufactured by cutting a metal plate using a cutter in which substantially triangular blades are arranged at a predetermined pitch. However, the ridges and valleys of this blade are not perfect corners due to manufacturing accuracy, and are usually rounded. Since the apex of the convex portion has a shape corresponding to the valley of the blade of the cutter, there is a problem that the apex of the convex portion is difficult to be angular and it is difficult to obtain a high slip coefficient.
本発明は上記の問題に鑑みてなされたものであり、高いすべり係数が得られる溝付板の製造方法を提供することを目的とする。 The present invention has been made in view of the above problems, and an object of the present invention is to provide a method for manufacturing a grooved veneer capable of obtaining a high slip coefficient.
前述した課題を解決するための本発明は、溝付板の製造方法であって、複数の略三角形状の刃を等ピッチで配列したカッタを用いて金属板を切削して溝を形成する工程（ａ）と、前記カッタを、nを2以上の整数として前記刃のピッチの1/nだけ前記金属板に対して前記刃の配列方向に相対移動させ、前記刃の山の深さ位置を前記溝の底部に合わせて前記カッタで前記金属板を切削する工程（ｂ）と、を有し、前記工程（ｂ）を(n-1)回繰り返すことを特徴とする溝付板の製造方法である。 The present invention for solving the above-mentioned problems is a method for manufacturing a grooved plate, which is a step of cutting a metal plate to form a groove using a cutter in which a plurality of substantially triangular blades are arranged at equal pitches. In (a), the cutter is moved relative to the metal plate by 1 / n of the pitch of the blade with n as an integer of 2 or more in the arrangement direction of the blade, and the depth position of the mountain of the blade is set. A method for manufacturing a grooved plate, which comprises a step (b) of cutting the metal plate with the cutter according to the bottom of the groove, and repeating the step (b) (n-1) times. Is.
これにより、本発明では、溝間の凸部の頂点が、カッタの刃の谷でなく刃の側面によって形成されることとなり、凸部の頂点を尖った角状に形成し、すべり係数を向上させることが可能になる。また複数の刃を用いて一度に複数の凸部を形成することで、短時間で手間なく加工ができる利点もある。 As a result, in the present invention, the apex of the convex portion between the grooves is formed not by the valley of the blade of the cutter but by the side surface of the blade, and the apex of the convex portion is formed into a sharp angular shape to improve the slip coefficient. It becomes possible to make it. Further, by forming a plurality of convex portions at a time by using a plurality of blades, there is an advantage that machining can be performed in a short time without hassle.
前記溝付板は例えばスプライスプレートである。
本発明では、上記のように溝間の凸部の頂点を尖った角状に形成してすべり係数を大きくできるため、スプライスプレートを用いた高力ボルト摩擦接合において高力ボルトの使用本数を削減することができると同時に、スプライスプレート自体もコンパクトにできるようになる。
The grooved plate is, for example, a splice plate.
In the present invention, since the apex of the convex portion between the grooves can be formed into a sharp angular shape as described above to increase the slip coefficient, the number of high-strength bolts used in high-strength bolt friction welding using a splice plate can be reduced. At the same time, the splice plate itself can be made compact.
前記工程（ｂ）の後に、前記金属板の前記溝の形成面に硬化処理を施すことが望ましい。
上記の硬化処理を施して凸部の表面の硬度を接合対象の鋼材よりも大きくすることで、凸部の頂点を鋼材に食い込ませてすべり止め効果を発揮させることができる。
After the step (b), it is desirable to perform a hardening treatment on the formed surface of the groove of the metal plate.
By performing the above hardening treatment to make the hardness of the surface of the convex portion larger than that of the steel material to be joined, the apex of the convex portion can be made to bite into the steel material to exert an anti-slip effect.
本発明により、高いすべり係数が得られる溝付板の製造方法を提供することができる。 INDUSTRIAL APPLICABILITY According to the present invention, it is possible to provide a method for manufacturing a grooved plate capable of obtaining a high slip coefficient.
以下、図面に基づいて本発明の好適な実施形態について詳細に説明する。 Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.
［第１の実施形態］
（１．スプライスプレート１００）
図１（ａ）は、本発明の第１の実施形態に係る溝付板の製造方法によって製造されるスプライスプレート１００（溝付板）を示す図である。
[First Embodiment]
(1. Splice plate 100)
FIG. 1A is a diagram showing a splice plate 100 (grooved plate) manufactured by the method for manufacturing a grooved plate according to the first embodiment of the present invention.
図１（ｂ）に示すように、スプライスプレート１００は例えば鉄骨梁においてＨ形鋼２００（鋼材）のウェブやフランジ（以下、ウェブ等という）同士を接合する際に用いられる。スプライスプレート１００は隣り合うＨ形鋼２００のウェブ等に沿って配置し、両ウェブ等に高力ボルト１０１やナット１０２等を用いて締結する。スプライスプレート１００には、例えば、一般構造用圧延鋼材、建築構造用圧延鋼材、溶接構造用圧延鋼材、機械構造用炭素鋼鋼材、機械構造用合金鋼鋼材などによる金属板が用いられる。なお図１（ａ）はウェブ同士を接合するスプライスプレート１００の例である。 As shown in FIG. 1 (b), the splice plate 100 is used, for example, when joining webs and flanges (hereinafter referred to as webs) of H-shaped steel 200 (steel material) in a steel beam. The splice plate 100 is arranged along the webs and the like of adjacent H-shaped steels 200, and is fastened to both webs and the like using high-strength bolts 101 and nuts 102. For the splice plate 100, for example, a metal plate made of rolled steel for general structure, rolled steel for building structure, rolled steel for welded structure, carbon steel for machine structure, alloy steel for machine structure, or the like is used. Note that FIG. 1A is an example of a splice plate 100 for joining webs to each other.
スプライスプレート１００では、ウェブ等に接する面に複数の溝１１が平行に並べて形成される。また、高力ボルト１０１を通すための貫通孔１２が形成される。 In the splice plate 100, a plurality of grooves 11 are formed in parallel on a surface in contact with a web or the like. In addition, a through hole 12 for passing the high-strength bolt 101 is formed.
図２はスプライスプレート１００の厚さ方向の断面を示す図である。本実施形態では、溝１１間の凸部が等ピッチで配列されており、その頂点が尖った角状で高いすべり係数が得られるものとなっている。凸部のピッチは例えば0.5mmから2mm程度であるが、これに限ることはない。また凸部の頂点の角度は例えば60°から120°程度であるが、すべり係数を高める上で最も好ましいのは90°である。 FIG. 2 is a view showing a cross section of the splice plate 100 in the thickness direction. In the present embodiment, the convex portions between the grooves 11 are arranged at equal pitches, and the apex is sharp and angular, and a high slip coefficient can be obtained. The pitch of the convex portion is, for example, about 0.5 mm to 2 mm, but is not limited to this. The angle of the apex of the convex portion is, for example, about 60 ° to 120 °, but 90 ° is the most preferable for increasing the slip coefficient.
一方、溝１１の底部は丸みを帯びているが、この底部はウェブ等に直接接触しないのですべり係数の点で特に問題は無い。また溝１１の底部に丸みがあることは、応力集中を緩和できる点で好ましい。 On the other hand, the bottom of the groove 11 is rounded, but since this bottom does not come into direct contact with the web or the like, there is no particular problem in terms of slip coefficient. Further, it is preferable that the bottom of the groove 11 is rounded because stress concentration can be relaxed.
また溝１１の形成面１１１の表層には硬化処理が施されており、前記したＨ形鋼２００のウェブ等の硬度よりも高い硬度となっている。 Further, the surface layer of the forming surface 111 of the groove 11 is subjected to a hardening treatment, and the hardness is higher than the hardness of the web or the like of the H-shaped steel 200 described above.
（２．スプライスプレート１００の製造方法）
次に、図３〜図６を用いてスプライスプレート１００の製造方法について説明する。
(2. Manufacturing method of splice plate 100)
Next, a method of manufacturing the splice plate 100 will be described with reference to FIGS. 3 to 6.
本実施形態では、図３（ａ）に示すように、同サイズの略三角形状の刃２１を直線状に複数配列したカッタ２を用いる。 In the present embodiment, as shown in FIG. 3A, a cutter 2 in which a plurality of substantially triangular blades 21 of the same size are linearly arranged is used.
図３（ｂ）に示すように、カッタ２では、刃２１の山２１１および谷２１２が等ピッチ（ピッチの長さをｐとする）で繰り返され、山２１１と谷２１２が若干の丸みを帯びている。このカッタ２を用いて金属板１０を切削することでスプライスプレート１００を製造する。 As shown in FIG. 3B, in the cutter 2, the peaks 211 and valleys 212 of the blade 21 are repeated at equal pitches (pitch length is p), and the peaks 211 and valleys 212 are slightly rounded. ing. The splice plate 100 is manufactured by cutting the metal plate 10 using the cutter 2.
本実施形態では、まず図４（ａ）に示すようにこのカッタ２で金属板１０を切削する。すると、図４（ｂ）に示すようにカッタ２の刃２１の形状に合わせた溝が金属板１０に形成される。溝の底部や溝間の凸部の頂点は、刃２１の山２１１や谷２１２の形状に対応して丸みを帯びたものとなっている。 In the present embodiment, the metal plate 10 is first cut by the cutter 2 as shown in FIG. 4A. Then, as shown in FIG. 4B, a groove matching the shape of the blade 21 of the cutter 2 is formed in the metal plate 10. The bottom of the groove and the apex of the convex portion between the grooves are rounded corresponding to the shapes of the peaks 211 and valleys 212 of the blade 21.
本実施形態では、次に、図５（ａ）に示すように、カッタ２を、上記のピッチｐの1/2だけ金属板１０に対して刃２１の配列方向（図の左右方向）に相対移動させ、図５（ｂ）に示すようにその位置で再び金属板１０を切削する。この時、刃２１の山２１１の深さ位置は金属板１０の溝の底部に合わせる。 In the present embodiment, as shown in FIG. 5A, the cutter 2 is placed relative to the metal plate 10 by 1/2 of the pitch p in the arrangement direction of the blades 21 (horizontal direction in the drawing). After moving, the metal plate 10 is cut again at that position as shown in FIG. 5 (b). At this time, the depth position of the ridge 211 of the blade 21 is aligned with the bottom of the groove of the metal plate 10.
これにより、図６に示すように、カッタ２の刃２１のピッチｐの1/2のピッチで溝１１間の凸部が繰り返す金属板１０が得られる。凸部の頂点は、カッタ２の刃２１の谷２１２でなく刃２１の側面によって削られているので、凸部の頂点は尖った角状のものとなる。 As a result, as shown in FIG. 6, a metal plate 10 in which the convex portions between the grooves 11 are repeated at a pitch of 1/2 of the pitch p of the blade 21 of the cutter 2 can be obtained. Since the apex of the convex portion is cut by the side surface of the blade 21 instead of the valley 212 of the blade 21 of the cutter 2, the apex of the convex portion has a sharp angular shape.
この後、本実施形態では溝１１の形成面１１１の表層のみに硬化処理を施し、貫通孔１２を形成することで、スプライスプレート１００を製造できる。硬化処理は、真空熱処理、浸炭焼入れ、浸炭窒化焼入れ、火炎焼入れ等の既知の熱処理手法（例えば特許文献１参照）により行うことができ、その硬度をＨ形鋼２００のウェブ等より大きくすることができる。また硬化処理を表層のみとしておくことで、貫通孔１２の形成が容易になる。 After that, in the present embodiment, the splice plate 100 can be manufactured by performing a hardening treatment only on the surface layer of the formation surface 111 of the groove 11 to form the through hole 12. The hardening treatment can be performed by a known heat treatment method (see, for example, Patent Document 1) such as vacuum heat treatment, carburizing quenching, carburizing nitride quenching, flame quenching, etc., and its hardness can be made larger than that of the web of H-section steel 200 or the like. it can. Further, by performing the hardening treatment only on the surface layer, the formation of the through hole 12 becomes easy.
（３．切削工具１）
図７（ａ）は上記のカッタ２を有する切削工具１の例である。この切削工具１は汎用のマシニングセンタ（不図示）のスピンドルに取付けて用いることが可能である。
(3. Cutting tool 1)
FIG. 7A is an example of a cutting tool 1 having the cutter 2 described above. This cutting tool 1 can be used by being attached to a spindle of a general-purpose machining center (not shown).
カッタ２は円筒状の回転体３の外周面に設けられ、刃２１の配列方向を回転体３の回転軸方向に合わせて配置される。カッタ２は回転体３の周方向に沿って複数設けられ、この回転体３を高速で回転させることでカッタ２の刃２１により金属板１０を切削することができる。 The cutter 2 is provided on the outer peripheral surface of the cylindrical rotating body 3, and is arranged so that the arrangement direction of the blades 21 is aligned with the rotation axis direction of the rotating body 3. A plurality of cutters 2 are provided along the circumferential direction of the rotating body 3, and the metal plate 10 can be cut by the blade 21 of the cutter 2 by rotating the rotating body 3 at a high speed.
回転体３の回転軸３１の両端は門型のフレーム４の脚部に取付けられ、回転体３を両持ち形式で保持している。これを片持ち形式とすると回転体３の回転時に回転体３が振動する恐れがあるが、両持ち形式とすることにより回転体３の振動を防止し精度の良い加工が可能になり、回転体３を長尺にすることも可能になる。 Both ends of the rotating shaft 31 of the rotating body 3 are attached to the legs of the gate-shaped frame 4, and hold the rotating body 3 in a double-sided manner. If this is a cantilever type, the rotating body 3 may vibrate when the rotating body 3 rotates. However, the double-sided type prevents the rotating body 3 from vibrating and enables highly accurate processing. It is also possible to make 3 longer.
フレーム４は筒状の取付部５によって上記のスピンドルに取り付けられる。取付部５はスピンドルの回転軸とは分離して取り付けられ、当該回転軸の回転によってはフレーム４が回転しないようになっている。一方、スピンドルの回転軸はフレーム４および取付部５の内部にある回転機構に接続され、この回転機構はスピンドルの回転軸の回転方向（図中Ａ参照）を回転体３の回転方向（図中Ｂ参照）に変換するためのかさ歯車等の変換部（不図示）を備えている。 The frame 4 is attached to the spindle by the tubular attachment portion 5. The mounting portion 5 is mounted separately from the rotating shaft of the spindle, and the frame 4 does not rotate due to the rotation of the rotating shaft. On the other hand, the rotation axis of the spindle is connected to a rotation mechanism inside the frame 4 and the mounting portion 5, and this rotation mechanism changes the rotation direction of the rotation axis of the spindle (see A in the figure) to the rotation direction of the rotating body 3 (in the figure). It is provided with a conversion unit (not shown) such as a bevel gear for converting to (see B).
図７（ａ）の例では金属板１０を立てて配置し回転体３の回転軸方向を鉛直としているが、図７（ｂ）に示すように金属板１０を水平方向に配置し回転体３の回転軸方向を水平としてもよい。前記したカッタ２の相対移動は、切削工具１の移動により行ってもよいし、金属板１０を配置したステージ（不図示）の移動により行ってもよい。 In the example of FIG. 7A, the metal plate 10 is arranged upright and the rotation axis direction of the rotating body 3 is vertical. However, as shown in FIG. 7B, the metal plate 10 is arranged horizontally and the rotating body 3 is arranged. The direction of the rotation axis of the may be horizontal. The relative movement of the cutter 2 may be performed by moving the cutting tool 1 or by moving a stage (not shown) on which the metal plate 10 is arranged.
以上説明したように、本実施形態では、溝１１間の凸部の頂点が、カッタ２の刃２１の谷２１２でなく刃２１の側面によって形成されることから、凸部の頂点を尖った角状に形成することができる。また複数の刃２１を用いて一度に複数の凸部を形成することで、短時間で手間なく加工ができる利点もある。 As described above, in the present embodiment, since the apex of the convex portion between the grooves 11 is formed not by the valley 212 of the blade 21 of the cutter 2 but by the side surface of the blade 21, the apex of the convex portion is a sharp angle. It can be formed into a shape. Further, by forming a plurality of convex portions at a time by using a plurality of blades 21, there is an advantage that machining can be performed in a short time and without trouble.
こうして溝１１間の凸部の頂点を尖った角状に形成することで、すべり係数を例えば0.9程度あるいはそれ以上に大きくすることができるため、スプライスプレート１００を用いた高力ボルト摩擦接合において、高力ボルト１０１の使用本数を削減することができると同時に、スプライスプレート１００自体をコンパクトにできるようになる。 By forming the apex of the convex portion between the grooves 11 into a sharp angular shape in this way, the slip coefficient can be increased to, for example, about 0.9 or more. Therefore, in high-strength bolt friction welding using the splice plate 100, The number of high-strength bolts 101 used can be reduced, and at the same time, the splice plate 100 itself can be made compact.
また、硬化処理を施して溝１１の形成面１１１の表層の硬度を接合対象の鋼材よりも大きくすることで、凸部の頂点を鋼材に食い込ませてすべり止め効果を発揮させることができる。 Further, by performing a hardening treatment to make the hardness of the surface layer of the formed surface 111 of the groove 11 larger than that of the steel material to be joined, the apex of the convex portion can be made to bite into the steel material to exert the anti-slip effect.
しかしながら、本発明はこれに限ることは無い。例えばスプライスプレート１００以外の溝付板を本実施形態の方法で作成することも可能である。また、切削工具１の取付対象はマシニングセンタのスピンドルに限ることもなく、カッタ２を有する切削工具１が上記の例に限られることもない。 However, the present invention is not limited to this. For example, a grooved plate other than the splice plate 100 can be produced by the method of the present embodiment. Further, the mounting target of the cutting tool 1 is not limited to the spindle of the machining center, and the cutting tool 1 having the cutter 2 is not limited to the above example.
以下、本発明の別の例について第２の実施形態として説明する。第２の実施形態は第１の実施形態と異なる点について説明し、同様の点については説明を省略する。 Hereinafter, another example of the present invention will be described as a second embodiment. The second embodiment will be described in terms of differences from the first embodiment, and the same points will be omitted.
[第２の実施形態]
第２の実施形態では、前記の図４（ｂ）と同様、カッタ２で金属板１０を切削した後、図８（ａ）に示すように、カッタ２を、刃２１のピッチｐの1/3だけ金属板１０に対して刃２１の配列方向（図の左右方向）に相対移動させ、図８（ｂ）に示すようにその位置で再び金属板１０を切削する。この時、刃２１の山２１１の深さ位置は金属板１０の溝の底部に合わせる。
[Second Embodiment]
In the second embodiment, as in FIG. 4B, after cutting the metal plate 10 with the cutter 2, as shown in FIG. 8A, the cutter 2 is used at 1 / of the pitch p of the blade 21. Only 3 is moved relative to the metal plate 10 in the arrangement direction of the blades 21 (left-right direction in the figure), and the metal plate 10 is cut again at that position as shown in FIG. 8 (b). At this time, the depth position of the ridge 211 of the blade 21 is aligned with the bottom of the groove of the metal plate 10.
次に、図９（ａ）に示すように、カッタ２を、再び刃２１のピッチｐの1/3だけ金属板１０に対して刃２１の配列方向に相対移動させ、図９（ｂ）に示すようにその位置で上記と同様に金属板１０を切削する。 Next, as shown in FIG. 9A, the cutter 2 is again moved relative to the metal plate 10 by 1/3 of the pitch p of the blade 21 in the arrangement direction of the blade 21, and is shown in FIG. 9B. As shown, the metal plate 10 is cut at that position in the same manner as described above.
これにより、図１０に示すように、カッタ２の刃２１のピッチｐの1/3のピッチで溝１１間の凸部が繰り返した金属板１０が得られる。この場合も、溝１１間の凸部の頂点は、カッタ２の刃２１の側面によって削られるため尖った角状のものとなる。以下、第１の実施形態と同様の硬化処理や貫通孔の形成を行うことで、スプライスプレートが製造できる。 As a result, as shown in FIG. 10, a metal plate 10 in which the convex portions between the grooves 11 are repeated at a pitch of 1/3 of the pitch p of the blade 21 of the cutter 2 can be obtained. Also in this case, the apex of the convex portion between the grooves 11 is sharpened by the side surface of the blade 21 of the cutter 2 and thus has a sharp angular shape. Hereinafter, the splice plate can be manufactured by performing the same hardening treatment and forming through holes as in the first embodiment.
このように、本発明では、カッタ２によって金属板１０を切削した後、カッタ２を刃２１のピッチの1/n（nは２以上の整数）だけ金属板１０に対して刃２１の配列方向に相対移動させ、カッタ２で金属板１０を切削する工程を(n-1)回繰り返すことで、カッタ２の刃２１のピッチの1/nのピッチで溝１１間の凸部を形成したスプライスプレートを製造できる。なお、この時溝１１の深さはカッタ２の刃２１の深さ（山２１１と谷２１２の高さの差）の1/nとなる。 As described above, in the present invention, after the metal plate 10 is cut by the cutter 2, the cutter 2 is placed in the arrangement direction of the blade 21 with respect to the metal plate 10 by 1 / n (n is an integer of 2 or more) of the pitch of the blade 21. By repeating the process of cutting the metal plate 10 with the cutter 2 (n-1) times, the splice formed a convex portion between the grooves 11 at a pitch of 1 / n of the pitch of the blade 21 of the cutter 2. Plates can be manufactured. At this time, the depth of the groove 11 is 1 / n of the depth of the blade 21 of the cutter 2 (the difference in height between the peaks 211 and the valleys 212).
