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 plate.
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 joining using a splice plate. In this case, the splice plate is disposed along both steel materials, and fastened to both steel materials using high strength bolts or nuts.
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 high-strength bolt friction joining is configured to ensure its proof strength 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, red rust is generated on the surface of the splice plate that contacts the steel material, or shot blasting is performed to ensure a predetermined slip coefficient (for example, 0.45 in the Architectural Institute of Japan's “Building Standard Specification JASS6”). .
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, the proof stress required for the joint tends to increase due to the recent increase in the tensile strength and cross section of steel materials. Therefore, it is possible to increase the number of high-strength bolts to improve the proof stress, but there is a problem that costs 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, an increase in the number of high strength bolts can be suppressed. Patent Documents 1 and 2 describe examples of grooved splice plates 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。 The splice plate having the convex portions 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 crests and troughs of the blades are not perfect corners because of manufacturing accuracy, and are usually rounded. Since the vertex of the convex portion has a shape corresponding to the valley of the cutter blade, the vertex of the convex portion is not easily formed into a square shape, and there is a problem that 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。 This invention is made | formed in view of said problem, and it aims at providing the manufacturing method of the board with a groove | channel from which a high slip coefficient is obtained.
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-described problem is a method for manufacturing a grooved plate, and a step of forming a groove by cutting a metal plate using a cutter in which a plurality of substantially triangular blades are arranged at an equal pitch. (A) and the cutter is moved relative to the metal plate by 1 / n of the blade pitch, where n is an integer of 2 or more, and the blade crest depth position is determined. A step (b) of cutting the metal plate with the cutter in accordance with the bottom of the groove, and the step (b) is repeated (n-1) times. It 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 cutter blade but by the side surface of the blade, and the apex of the convex portion is formed in a sharp corner, improving the slip coefficient. It becomes possible to make it. In addition, forming a plurality of convex portions at a time using a plurality of blades also has an advantage that processing can be performed in a short time without trouble.
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, as described above, the peak of the convex portion between the grooves can be formed into a sharp corner to increase the slip coefficient, so the number of high-strength bolts used in high-strength bolt friction welding using a splice plate is 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 curing process on the groove forming surface of the metal plate.
By applying the above-described hardening treatment to make the surface hardness of the convex portion larger than that of the steel material to be joined, the top of the convex portion can be bitten into the steel material and the anti-slip effect can be exhibited.
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。 According to the present invention, it is possible to provide a method for manufacturing a grooved plate that can provide 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.1 (a) is a figure which shows the splice plate 100 (grooved board) manufactured by the manufacturing method of the grooved board which concerns on the 1st Embodiment of this 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 when joining the web and flange (henceforth a web etc.) of H-section steel 200 (steel material), for example in a steel beam. The splice plate 100 is disposed along the webs of adjacent H-shaped steels 200 and fastened to both webs using high strength bolts 101, nuts 102, and the like. 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. FIG. 1A shows an example of a splice plate 100 that joins webs.
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 the surface in contact with the web or the like. Moreover, the through-hole 12 for letting the high strength bolt 101 pass 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 an equal pitch, and a high slip coefficient is obtained with a corner shape having a sharp apex. The pitch of the convex portions is, for example, about 0.5 mm to 2 mm, but is not limited thereto. Further, the angle of the vertex of the convex portion is, for example, about 60 ° to 120 °, and 90 ° is 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, although the bottom of the groove 11 is rounded, the bottom does not directly contact the web or the like, so there is no problem in terms of the 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 hardened, and has a hardness higher than the hardness of the web 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 for manufacturing the splice plate 100 will be described with reference to FIGS.
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 this embodiment, as shown in FIG. 3A, a cutter 2 in which a plurality of substantially triangular blades 21 of the same size are arranged in a straight line 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 crest 211 and the trough 212 of the blade 21 are repeated at an equal pitch (pitch length is p), and the crest 211 and the trough 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, first, the metal plate 10 is cut by the cutter 2 as shown in FIG. Then, the groove | channel according to the shape of the blade 21 of the cutter 2 is formed in the metal plate 10, as shown in FIG.4 (b). The apex of the bottom of the groove or the convex part between the grooves is rounded corresponding to the shape of the crest 211 or trough 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。 Next, in this embodiment, as shown in FIG. 5A, the cutter 2 is moved relative to the metal plate 10 in the arrangement direction of the blades 21 (the left-right direction in the drawing) by 1/2 of the pitch p. The metal plate 10 is cut again at that position as shown in FIG. At this time, the depth position of the crest 211 of the blade 21 is adjusted to 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。 Thereby, as shown in FIG. 6, a metal plate 10 is obtained in which convex portions between the grooves 11 are repeated at a pitch ½ of the pitch p of the blades 21 of the cutter 2. 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 is a sharp corner.
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。 Thereafter, in the present embodiment, the splice plate 100 can be manufactured by performing the curing process only on the surface layer of the formation surface 111 of the groove 11 to form the through hole 12. The hardening process can be performed by a known heat treatment method (for example, see Patent Document 1) such as vacuum heat treatment, carburizing and quenching, carbonitriding and quenching, or flame quenching, and the hardness thereof can be made larger than the web of the H-section steel 200 or the like. it can. Moreover, the formation of the through hole 12 is facilitated by setting the curing process to the surface layer only.
（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 shows an example of the cutting tool 1 having the cutter 2 described above. The 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 matches 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 leg portions of the gate-shaped frame 4, and the rotating body 3 is held in a doubly supported manner. If this is a cantilever type, the rotary body 3 may vibrate when the rotary body 3 is rotated. However, by using the double-supported type, the rotary body 3 can be prevented from being vibrated and processed accurately. 3 can be made long.
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 a cylindrical attachment portion 5. The attachment portion 5 is attached separately from the spindle of the spindle, and the frame 4 is not rotated by the rotation of the spindle. On the other hand, the rotating shaft of the spindle is connected to a rotating mechanism inside the frame 4 and the mounting portion 5, and this rotating mechanism determines the rotating direction of the rotating shaft of the spindle (see A in the figure) as the rotating direction of the rotating body 3 (in the figure). A conversion unit (not shown) such as a bevel gear is provided for conversion into (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 placed upright and the rotation axis direction of the rotating body 3 is vertical, but the metal plate 10 is arranged in the horizontal direction as shown in FIG. The rotation axis direction 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, 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, so that the apex of the convex portion is sharpened. Can be formed. In addition, forming a plurality of convex portions at a time using a plurality of blades 21 has an advantage that processing 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。 Since the slip coefficient can be increased to, for example, about 0.9 or more by forming the apex of the convex portion between the grooves 11 in this way, in the high-strength bolt friction joint 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。 Moreover, by applying a hardening process to make the hardness of the surface layer of the formation surface 111 of the groove 11 larger than that of the steel material to be joined, the top of the convex portion can be bitten into the steel material and the anti-skid effect can be exhibited.
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 this embodiment. Further, the attachment 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 with respect to differences from the first embodiment, and description of similar 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, after cutting the metal plate 10 with the cutter 2 as shown in FIG. 4B, the cutter 2 is moved to 1 / of the pitch p of the blade 21 as shown in FIG. 8A. Only 3 is moved relative to the metal plate 10 in the arrangement direction of the blades 21 (left and right direction in the figure), and the metal plate 10 is cut again at that position as shown in FIG. At this time, the depth position of the crest 211 of the blade 21 is adjusted to 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 in the arrangement direction of the blades 21 by 1/3 of the pitch p of the blades 21 again. As shown, the metal plate 10 is cut 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, the metal plate 10 is obtained in which the convex portions between the grooves 11 are repeated at a pitch 1/3 of the pitch p of the blade 21 of the cutter 2. Also in this case, the apex of the convex portion between the grooves 11 is sharpened because it is scraped by the side surface of the blade 21 of the cutter 2. Hereinafter, the splicing plate can be manufactured by performing the same curing treatment as in the first embodiment and the formation of the through holes.
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。 Thus, in the present invention, after cutting the metal plate 10 with the cutter 2, the cutter 2 is arranged in the arrangement direction of the blades 21 with respect to the metal plate 10 by 1 / n of the pitch of the blades 21 (n is an integer of 2 or more). The process of cutting the metal plate 10 with the cutter 2 is repeated (n-1) times to form a projection between the grooves 11 at a pitch 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 crest 211 and the trough 212).
以上、添付図面を参照して、本発明の好適な実施形態について説明したが、本発明は係る例に限定されない。当業者であれば、本願で開示した技術的思想の範疇内において、各種の変更例または修正例に想到し得ることは明らかであり、それらについても当然に本発明の技術的範囲に属するものと了解される。 The preferred embodiments of the present invention have been described above with reference to the accompanying drawings, but the present invention is not limited to such examples. It will be apparent to those skilled in the art that various changes or modifications can be conceived within the scope of the technical idea disclosed in the present application, and these are naturally within the technical scope of the present invention. Understood.
