Description

本発明は、トムソン刃の曲げ加工するため溝削り加工装置に関する。   The present invention relates to a grooving apparatus for bending a Thomson blade.

従来、トムソン刃１をV曲げ加工する場合、基本的には前もって機械削りを行わずそのまま曲げ加工を行っていた。コ−ナ−に薄い厚さ１．０mm前後の切断砥石で溝加工して曲げを行うと鋭角な曲げが出来ることは知られていたが、煩わしいのと位置精度が出にくいので、実際にはほとんど使われていなかった。この場合でも切断砥石では溝はア−ル形状で折り曲げ位置が決まらず、切り込み深さが砥石の摩耗のため毎回一定していなかったのでコ−ナ−曲げ半径も変わっていた。 Conventionally, when the Thomson blade 1 is bent by V, the bending is basically performed without machining in advance. It has been known that sharp corners can be bent by grooving with a cutting grindstone with a thickness of around 1.0 mm in the corner, but it is bothersome and difficult to obtain position accuracy. It was hardly used. Even in this case, in the cutting grindstone, the groove had an alarm shape, the bending position was not determined, and the cutting depth was not constant every time due to the wear of the grindstone, so the corner bending radius also changed.

既成のトムソン刃１自動曲げ機部Aのとりわけ曲げ機構部は、微妙な隙間で構成され、そこに切削屑等が入ると曲げ精度がでなくなり、トムソン刃１の自動送りでのジャミングの原因にもなる。そのために切削屑が自動曲げ機部Aに影響を与えないことが絶対必要条件である。又、トムソン刃１を先鋭に曲げるためにトムソン刃１に予めV字溝を入れるためには下記の課題がある。 Especially the bending mechanism part of the existing Thomson blade 1 automatic bending machine part A is composed of a delicate gap, and if cutting debris enters there, the bending accuracy will be lost, causing jamming in the automatic feeding of the Thomson blade 1 Also become. Therefore, it is an absolutely necessary condition that the cutting waste does not affect the automatic bending machine part A. In order to bend the V-shaped groove in the Thomson blade 1 in order to bend the Thomson blade 1 sharply, there are the following problems.

イ）自動曲げ機部Aの追加機能として自動曲げ機部Aより十分離して、溝加工部Bを設置しトムソン刃１の両側にV字溝加工し、その後、自動曲げ機部AでV字溝を施した箇所を先鋭に曲げるためのトムソン刃溝削り加工装置。 B) As an additional function of the automatic bending machine part A, it is separated from the automatic bending machine part A, and a grooving part B is installed and V-shaped grooving is performed on both sides of the Thomson blade 1, and then V-shaped by the automatic bending machine part A. Thomson blade grooving machine for sharply bending grooves.

ロ）トムソン刃１の両側にV字溝を施すことにより、トムソン刃１の曲げ要素間距離を短くするトムソン刃溝削り加工装置。 B) A Thomson blade grooving device that shortens the distance between bending elements of the Thomson blade 1 by forming V-shaped grooves on both sides of the Thomson blade 1.

ハ）コ−ナ−部での曲げ形状の乱れ、折り曲げ点での底の盛り上がりを無くし、抜き型完成後の切れむらを無くすトムソン刃溝削り加工装置。 C) A Thomson blade grooving machine that eliminates irregular bending shapes at the corners and rise of the bottom at the bending point, and eliminates unevenness after completion of the punching die.

ニ）トムソン刃１の刃先のすぐ手前まで正確な角溝を加工できることにより、トムソン刃１の組み合わせ時に、刃先を相手側に密着、切れむらの無いトムソン刃溝削り加工装置。 D) A Thomson blade grooving machine that can cut an accurate square groove just before the blade tip of the Thomson blade 1 so that the blade tip is in close contact with the other side when the Thomson blade 1 is combined, and there is no unevenness.

本発明は、図５(ｄ)に示すように、トムソン刃１の両側の必要な位置に最小ピッチで正確なV字溝加工ができることにより、小さな曲げ力でもコ−ナ−半径の小さい要素間ピッチの小さいトムソン刃１の曲げ加工できるトムソン刃溝削り加工装置を提供する。 As shown in FIG. 5 (d), the present invention enables accurate V-groove machining at a required position on both sides of the Thomson blade 1 with a minimum pitch, so that an element having a small corner radius can be obtained even with a small bending force. Provided is a Thomson blade grooving apparatus capable of bending a Thomson blade 1 having a small pitch.

本発明は、図２に示すように、自動曲げ機部Aから送り出したトムソン刃１にV字溝を削り、その切り粉が発生しても自動曲げ機部Aに悪影響の出にくい場所に設置された溝加工部Bであって、溝加工部Bにはトムソン刃１の両側にV字溝を削ることができるV字溝堀案内ユニット２２と、それを上下左右に移動させる左右移動機構部１０，上下移動機構部１５及び支持部１６を有する。自動曲げ機部Aからトムソン刃１を、溝加工部Bに送り出し、トムソン刃１にそれと直角の方向に左右のV字溝を加工し、その後、自動曲げ機部Aに引き戻して、V字溝を施した箇所を先鋭に曲げる。 As shown in FIG. 2, the present invention cuts the V-shaped groove on the Thomson blade 1 fed from the automatic bending machine part A, and installs it in a place where the automatic bending machine part A is not adversely affected even if chips are generated. Grooving section B, which includes a V-shaped groove guide unit 22 capable of cutting V-shaped grooves on both sides of the Thomson blade 1, and a left-right moving mechanism section for moving the groove vertically and horizontally 10. It has a vertical movement mechanism part 15 and a support part 16. Thomson blade 1 is sent from automatic bending machine part A to grooving part B, and left and right V-shaped grooves are machined into Thomson blade 1 in the direction perpendicular to it, and then pulled back to automatic bending machine part A to form V-shaped groove. Sharply bend the part that has been subjected to.

本発明のV字溝堀案内ユニット２２は、図１に示すように、上下左右移動可能な案内治具ベ−ス１７と、それに接続された溝削り案内治具５、取り付け板３と、溝削りモ−タ１１により駆動される溝削り刃物９を有し、溝削り案内治具５にはトムソン刃１の刃厚より若干広い左右一対の細溝１２がある。その先端はトムソン刃１の左右の振れに対して溝削り案内治具５が入りやすいように開先になっている。その細溝１２に溝削り刃物９をトムソン刃１の切り込み量覗かせて、V字溝堀案内ユニット２２を、上下左右移動させて、図３（ｂ）（ｃ）に示すように、上から溝削り案内治具５の細溝１２に沿ってトムソン刃１に挿入してその左右に溝をいれる。   As shown in FIG. 1, the V-shaped groove guide unit 22 of the present invention includes a guide jig base 17 that can be moved up and down, left and right, a groove cutting guide jig 5 connected thereto, a mounting plate 3, and a groove. A groove cutting tool 9 is driven by a cutting motor 11, and the groove cutting guide jig 5 has a pair of left and right narrow grooves 12 slightly wider than the blade thickness of the Thomson blade 1. The tip is a groove so that the groove cutting guide jig 5 can easily enter the left and right swings of the Thomson blade 1. As shown in FIGS. 3 (b) and 3 (c), the V-groove guide unit 22 is moved up, down, left, and right through the narrow groove 12 and the grooving blade 9 is viewed through the cutting amount of the Thomson blade 1. The groove cutting guide jig 5 is inserted into the Thomson blade 1 along the narrow groove 12 and grooves are formed on the left and right.

溝削りを数回の切り込みでするときは、V字溝堀案内ユニット２２に切り込み調整駆動部１８、送りネジ１９を取り付け、取り付け具２０は案内治具ベ−ス１７に摺動取り付けする。両側の溝削り刃物９を細溝１２からでる手前で固定ネジ８を締め付ける。この状態で左右一対の溝削り刃物９は切り込み設定時に動かさず、被加工物のトムソン刃１をはさんでいる溝削り案内治具５のみを左右移動させて切り込み量を設定してトムソン刃１の左右に溝加工する。 When the grooving is performed several times, the notch adjusting drive unit 18 and the feed screw 19 are attached to the V-shaped groove guide unit 22, and the mounting tool 20 is slidably attached to the guide jig base 17. The fixing screw 8 is tightened before the grooved cutting tool 9 on both sides comes out of the narrow groove 12. In this state, the pair of left and right grooving blades 9 do not move at the time of cutting setting, and only the grooving guide jig 5 sandwiching the Thomson blade 1 of the workpiece is moved left and right to set the cutting amount to set the cutting amount. Groove on the left and right of the.

V字溝堀案内ユニット２２において、左右一対の溝幅の異なる細溝１２の溝削り案内治具５を、取り付け具２０より脱着することにより、異なる刃厚のトムソン刃１の溝削り案内治具５に交換する。 In the V-shaped groove guide unit 22, the groove guide jig 5 of the Thomson blade 1 having different blade thicknesses is obtained by detaching the groove guide jig 5 of the narrow groove 12 having a different left and right groove width from the attachment tool 20. Change to 5.

華奢な機械構造にもかかわらずトムソン刃１の両側の必要な位置に最小ピッチで正確な溝加工ができることにより、図５のようなコ−ナ−半径の小さい要素間ピッチの小さいトムソン刃１曲げ加工が出来るようになる。 Despite the delicate mechanical structure, it is possible to perform accurate grooving at a required position on both sides of the Thomson blade 1 with a minimum pitch, so that the Thomson blade 1 bend with a small corner radius and a small pitch between elements as shown in FIG. Can be processed.

図５は、本発明のトムソン刃１にV字溝を作成し、曲げ加工する工程を示す。
トムソン刃１を、図５(b) (c)の溝加工無しで曲げ加工すると、刃厚の中立線上に対して刃の内側では圧縮応力が、外側では引っ張り応力がかってくる。そのためにコ−ナ−部の曲げ形状が乱れる。特に最小曲げ半径、および内側は押されてトムソン刃１の高さ方向に歪み、内側は底が飛び出し刃高が長くなり、打ち抜き時に切れむら、形状むらを生じる。 FIG. 5 shows a process of creating and bending a V-shaped groove in the Thomson blade 1 of the present invention.
When the Thomson blade 1 is bent without grooving shown in FIGS. 5B and 5C, a compressive stress is applied on the inner side of the blade and a tensile stress is applied on the outer side with respect to the neutral line of the blade thickness. Therefore, the bent shape of the corner portion is disturbed. In particular, the minimum bending radius and the inside are pushed and distorted in the height direction of the Thomson blade 1, and the inside protrudes from the bottom and the blade height becomes long, resulting in unevenness and uneven shape during punching.

図５(b)のようにV字溝を加工後(ｄ)のように曲げ加工すると、圧縮応力がかからないので、トムソン刃１の底の部分が出っ張らず、最小半径で曲げられる。またV字溝なので曲げ位置も決まり、左右にV字溝を入れると角溝に比べ、隣の溝との干渉も少なくできる。 When the V-shaped groove is bent as shown in FIG. 5 (b) and then bent as shown in (d), no compressive stress is applied, so that the bottom portion of the Thomson blade 1 does not protrude and is bent with the minimum radius. The V-shaped groove also determines the bending position. Inserting V-shaped grooves on the left and right can reduce interference with adjacent grooves compared to square grooves.

本発明では、自動曲げ機部Aからトムソン刃１を、前もって溝加工部Bに引き出し、図５（ｂ）のV字溝または図５（ｃ）の角溝をいれて、その後引き戻し、既成の自動曲げ機部Aで曲げることにより、コ−ナ半径の小さな折り曲げ点で底の盛り上げることなく、図５（ｄ）のように短い要素間でも少しの曲げ力で決まった位置にくっきりと曲げられる。また、図５(ｃ)の角溝を加工することにより、図５(e)のようにトムソン刃１の組み合わせ時に、刃先を相手側により密着できる。 In the present invention, the Thomson blade 1 is drawn from the automatic bending machine part A to the groove processing part B in advance, and the V-shaped groove of FIG. 5B or the square groove of FIG. By bending with the automatic bending machine part A, it is possible to bend clearly at a fixed position with a slight bending force even between short elements as shown in FIG. 5D without raising the bottom at a bending point with a small corner radius. . Further, by machining the square groove of FIG. 5C, the cutting edge can be brought into close contact with the counterpart when the Thomson blade 1 is combined as shown in FIG. 5E.

図１はV字溝掘り案内ユニット２２の構成を示す。
V字溝堀案内ユニット２２は上下左右移動可能な案内治具ベ−ス１７と、それに接続された左右一対の細溝１２付き溝削り案内治具５と、溝削りモ−タ１１により駆動される
溝削り刃物９を有し、トムソン刃１の切り込み量だけ、溝削り刃物９を溝削り案内治具５の左右一対の開先つき細溝１２より覗かせて、案内治具ベ−ス１７ごと、上下左右移動させて、トムソン刃１の直角の方向にV字溝を加工する。 FIG. 1 shows the configuration of the V-shaped grooving guide unit 22.
The V-shaped groove guide unit 22 is driven by a guide jig base 17 that can be moved up and down, left and right, a pair of left and right narrow groove guide guides 5 with a narrow groove 12, and a groove motor 11. The grooved cutting tool 9 is provided, and the grooved cutting tool 9 is viewed from the pair of left and right narrow grooves 12 of the grooved guiding jig 5 by the cutting amount of the Thomson blade 1, and the guide jig base 17 Each is moved up, down, left and right, and a V-shaped groove is machined in the direction perpendicular to the Thomson blade 1.

詳細には、V字溝堀案内ユニット２２には、案内治具ベ−ス１７に取り付け具２０、一対の取り付け板３，切り込み調整部１８が取り付けられ、取り付け具２０には一対の細溝１２のある溝削り案内治具５が脱着可能に取り付き、取り付け板３には溝削りモ−タ１１がその先には溝削り刃物９が取り付いている。取り付け板３は案内治具ベ−ス１７に摺動固定され調整ネジ７により溝削り刃物９の切り込み量を調整し、固定ネジ８で案内治具ベ−ス１７に固定される。案内治具ベ−ス１７には左右移動機構部１０，上下移動機構部１５が取り付けられ、片持ち支持部１６により支えられている。 Specifically, in the V-shaped groove guide unit 22, a mounting tool 20, a pair of mounting plates 3, and a cut adjustment portion 18 are mounted on the guide jig base 17, and the mounting tool 20 has a pair of narrow grooves 12. A grooving guide jig 5 is detachably attached, a grooving motor 11 is attached to the mounting plate 3, and a grooving blade 9 is attached to the tip of the mounting plate 3. The mounting plate 3 is slidably fixed to the guide jig base 17, the cutting amount of the grooving blade 9 is adjusted by the adjusting screw 7, and is fixed to the guide jig base 17 by the fixing screw 8. The guide jig base 17 is provided with a left / right moving mechanism 10 and an up / down moving mechanism 15 and supported by a cantilever support 16.

図２は自動曲げ機部A 溝加工部Bの全体構造を示す。
溝加工部Bにはトムソン刃１の両側にV字溝を削ることができるV字溝堀案内ユニット２２と、それを上下左右に移動させる左右移動機構部１０，上下移動機構部１５及び支持部１６を有する。自動曲げ機部Aからトムソン刃１を、溝加工部Bに送り出し、トムソン刃１にそれと直角の方向に左右のV字溝を加工し、その後、自動曲げ機部Aに引き戻して、V字溝を施した箇所を先鋭に曲げる。 FIG. 2 shows the entire structure of the automatic bending machine part A grooving part B.
The groove processing section B includes a V-shaped groove guide unit 22 capable of cutting V-shaped grooves on both sides of the Thomson blade 1, a left-right moving mechanism section 10, a vertical moving mechanism section 15, and a support section for moving the groove section vertically and horizontally. 16 The Thomson blade 1 is sent from the automatic bending machine part A to the grooving part B, and the left and right V-shaped grooves are machined in the direction perpendicular to the Thomson blade 1, and then pulled back to the automatic bending machine part A to obtain the V-shaped groove. Sharply bend the part that has been subjected to.

溝削り刃物９が溝削り案内治具５の刃物進入窓１３の中を通って細溝１２に達し、溝削り刃物９の両側に溝削り案内治具５が近接して設置できるので、切削時のトムソン刃１の細溝による拘束がより安定する。 Since the grooving cutter 9 passes through the cutter entry window 13 of the grooving guide jig 5 and reaches the narrow groove 12, and the grooving guide jig 5 can be installed on both sides of the grooving cutter 9, so that it can be cut. The Thomson blade 1 is more stably restrained by the narrow groove.

溝削り刃物９が溝削り案内治具５の一対の細溝１２から切り込み量覗いた状態でトムソン刃１の上から下りてくると細溝１２の幅がトムソン刃１の厚さに対して十分狭いので、切削時にトムソン刃１が拘束され溝深さの一定した溝が削れる。 When the grooving tool 9 descends from the top of the Thomson blade 1 while looking through the pair of narrow grooves 12 of the grooving guide jig 5, the width of the narrow groove 12 is sufficient with respect to the thickness of the Thomson blade 1. Since it is narrow, the Thomson blade 1 is restrained at the time of cutting, and a groove having a constant groove depth can be cut.

１回の切り込みで溝削りをする時は、切り込み調整駆動部１８と送りネジ１９は取り付けず、取り付け具２０は案内治具ベ−ス１７に直接固定する。そして調整ネジ７で取り付け板３を摺動させ、刃物進入窓１３より溝削り刃物９を挿入し細溝１２より溝の切り込み量のぞかせる。図３（ｂ）の様にトムソン刃１１の左側に溝を入れる時は案内治具ベ−ス１７を右に溝削り案内治具５の細溝１２がトムソン刃１の真上まで移動させ、その後,下に移動させ切削加工をし、上にあげる。次に図３（C）のようにトムソン刃１の右側に溝を入れる時は同様に案内治具ベ−ス１７を左にトムソン刃１の真上まで移動させ下に移動させ切削加工を行い、上にあげる。 When grooving with a single cut, the cut adjustment drive unit 18 and the feed screw 19 are not attached, and the fixture 20 is fixed directly to the guide jig base 17. Then, the mounting plate 3 is slid with the adjusting screw 7, and the grooved cutting tool 9 is inserted from the blade entry window 13, and the groove cutting depth is shown through the narrow groove 12. As shown in FIG. 3B, when a groove is made on the left side of the Thomson blade 11, the guide jig base 17 is moved to the right, and the narrow groove 12 of the guide jig 5 is moved to a position directly above the Thomson blade 1. Then move it down and cut it up. Next, when inserting a groove on the right side of the Thomson blade 1 as shown in FIG. 3C, similarly, the guide jig base 17 is moved to the left just above the Thomson blade 1 and moved downward to perform cutting. I'll give it up.

トムソン刃１が硬いか、又は刃厚が厚い時は複数回の切り込みの加工が必要になる。その時はV字溝堀案内ユニット２２に切り込み調整駆動部１８と送りネジ１９を取り付け、取り付け具２０は案内治具ベ−ス１７に摺動取り付けする。機械構造が華奢なため、まず振動元の両側のモ−タ取り付け板３を調整ネジ７で摺動させ、刃物進入窓１３を通り溝削り刃物９が細溝１２手前まで移動させて固定ネジ８を締め付ける。この状態で溝削り案内治具５と溝削り刃物９の相対関係において、左右一対の溝削り刃物９は切り込み設定時に動かさず、被加工物のトムソン刃１を挟んでいる溝削り案内治具５のみを左右移動させて切り込み量を設定してトムソン刃１の左右に溝加工する。これにより本来なら左右一対必要な切り込み装置が一つに減らされ、V字溝堀案内ユニット２２が軽量化できる。 When the Thomson blade 1 is hard or the blade thickness is thick, a plurality of incisions are required. At that time, the notch adjusting drive unit 18 and the feed screw 19 are attached to the V-shaped groove guide unit 22, and the mounting tool 20 is slidably attached to the guide jig base 17. Since the mechanical structure is delicate, first, the motor mounting plates 3 on both sides of the vibration source are slid with the adjusting screw 7, and the grooving blade 9 is moved to the front of the narrow groove 12 through the blade entry window 13 to fix the fixing screw 8. Tighten. In this state, in the relative relationship between the grooving guide jig 5 and the grooving cutter 9, the pair of left and right grooving knives 9 do not move at the time of incision setting, and the grooving guide jig 5 sandwiches the Thomson blade 1 of the workpiece. Only the right and left are moved to set the cutting amount, and the left and right of the Thomson blade 1 are grooved. As a result, the pair of left and right cutting devices that are originally required are reduced to one, and the V-shaped groove guide unit 22 can be reduced in weight.

トムソン刃１の刃厚が変わっても溝削り案内治具５のみの交換ですぐに対応できる。 Even if the blade thickness of the Thomson blade 1 changes, it can be dealt with immediately by replacing only the groove cutting guide jig 5.

図３はV字溝堀案内ユニット２２に取り付いた案内治具ベ−ス１７が刃送り案内板４に沿ったトムソン刃１の通り線上に左右に振った状態を示す。 FIG. 3 shows a state in which the guide jig base 17 attached to the V-shaped groove guide unit 22 is swung left and right on the Thomson blade 1 along the blade feed guide plate 4.

図４は既成自動曲げ機部とV字溝堀案内ユニット２２を上面から見た図を示す。図２のようにトムソン刃１より若干溝幅の広い（約0.1mm）左右一対の溝付き案内治具５とその中に移動可能な溝削り刃物９を設置し、細溝１２に対して溝削り刃物９の刃の出る量を切り込みネジ７で設定し、図３ (b) (c)のように溝付き案内治具５と溝削り刃物９を右に左側細溝がトムソン刃１の真上まで移動させ、溝削り刃物９を回転させながら、案内ベ−ス１７ごと下降させ固定式クランプでない、摺動式の溝付き案内治具５と溝削り刃物９でトムソン刃１の左側面の溝削り後、溝削り刃物９を上昇させトムソン刃１を進行方向に必要量送り、図３のように溝付き案内治具５を左に右側の細溝がトムソン刃１の真上まで移動させ再び案内ベ−ス１７を下降させ右側面の溝削りをする。このとき上から降りてくる細溝１２によりトムソン刃１の動きが拘束されるので切り込み一定の溝加工が加工可能になる。 FIG. 4 shows a view of the existing automatic bending machine section and the V-shaped groove guide unit 22 as seen from above. As shown in FIG. 2, a pair of left and right grooved guide jigs 5 having a slightly wider groove width (about 0.1 mm) than Thomson blade 1 and movable grooved cutting tool 9 are installed therein, and grooved with respect to narrow groove 12. Set the amount of sharpening of the cutting tool 9 with the cutting screw 7, as shown in FIGS. 3 (b) and 3 (c), the grooved guide jig 5 and the grooved cutting tool 9 are on the right and the left narrow groove is the true of the Thomson blade 1. Move to the top, rotate the grooving blade 9 and lower it together with the guide base 17, and slide it on the left side of the Thomson blade 1 with the slidable grooved guide jig 5 and the grooving blade 9. After grooving, the grooving blade 9 is raised to feed the required amount of Thomson blade 1 in the traveling direction, and the grooved guide jig 5 is moved to the left as shown in FIG. The guide base 17 is lowered again and the right side surface is grooved. At this time, since the movement of the Thomson blade 1 is restrained by the narrow groove 12 descending from above, it is possible to process a groove with a constant cut.

図５は、本発明のV溝加工によるトムソン刃１を曲げ加工する工程を示す。
(a)は曲げ加工前のトムソン刃１（普通厚み0.7mm,高さ23.6mmで寸法は各種）、(ｂ)はV溝加工されたトムソン刃１を上から見た図、(ｃ)は角溝加工されたトムソン刃１を上から見た図、(ｄ)はV溝加工されたトムソン刃１を曲げた図、(e )はトムソン刃１を直角に組み合わせた図である。V字溝を入れておくと曲げに要する力も少なくてすむので、最小要素間距離で曲げるのに役立つ。 FIG. 5 shows a process of bending the Thomson blade 1 by the V-groove processing of the present invention.
(a) is the Thomson blade 1 before bending (normal thickness 0.7mm, height 23.6mm, various dimensions), (b) is a top view of the V-grooved Thomson blade 1, (c) is The figure which looked at the Thomson blade 1 which carried out the square groove processing from the top, (d) is the figure which bent the Thomson blade 1 which carried out V groove processing, (e) is the figure which combined the Thomson blade 1 at right angle. V-grooves can be bent with the minimum distance between elements because less bending force is required.

ところがトムソン刃１を曲げる時に、トムソン刃１が左右に振られるため溝加工部と干渉する。また左右の溝も最小ピッチでいれたいので、バイス等の強固なクランプを設置しにくい、またスペ−ス的にも自動曲げ機部Aとの取り付けも片持ち構造などにならざるをえないので溝加工装置も頑強に作りにくい。 However, when the Thomson blade 1 is bent, since the Thomson blade 1 is swung left and right, it interferes with the groove processing portion. Also, since the left and right grooves need to be placed at the minimum pitch, it is difficult to install a strong clamp such as a vise, and the space and the automatic bending machine part A must be mounted in a cantilever structure. Grooving equipment is also difficult to make stubbornly.

自動曲げ機部Aより前方に引き出せば、図４のように、刃送り案内板４を取り付けられないので進行方向に真っ直ぐに引き出せず左右に振られた状態で、かつ垂直方向に倒れた不安定な状態になる。また、溝削り刃物９は片持ちで機械剛性を得にくい構造なので、位置決め精度が出しにくく切り込み深さがばらつきやすい。この加工物、被加工物の相対位置が不安定なのに正確な深さの溝加工が必要である。ところが、溝削り案内治具の細溝１２は先端部が開いており、トムソン刃１の位置がずれていてもひねっていても、細溝１２の開口部以内のばらつきであれば、V字溝堀案内ユニット２２の下降とともにトムソン刃１が細溝１２内に挿入され正確な深さの溝加工が可能となる。 If it is pulled forward from the automatic bending machine part A, the blade feed guide plate 4 cannot be attached as shown in FIG. 4, so it cannot be pulled straight in the direction of travel and is shaken to the left and right and is unstable in the vertical direction. It becomes a state. Further, since the grooving cutter 9 is cantilevered and it is difficult to obtain mechanical rigidity, positioning accuracy is difficult to obtain and the cutting depth is likely to vary. Although the relative position of the workpiece and the workpiece is unstable, grooving with an accurate depth is required. However, the narrow groove 12 of the grooving guide jig is open at the tip, and even if the position of the Thomson blade 1 is shifted or twisted, if the variation is within the opening of the narrow groove 12, the V-shaped groove As the moat guide unit 22 descends, the Thomson blade 1 is inserted into the narrow groove 12, and a groove with an accurate depth can be processed.

このように機械側、被削材側の不安定な姿勢の条件下でその両側面に正確な深さの切り込みを、進行方向に最小ピッチの溝加工を曲げる前に両側にすることにより最小コ−ナ-曲げ半径0.1mmを可能にする。 In this way, under the condition of unstable posture on the machine side and work material side, the minimum depth can be cut by making accurate depth cuts on both sides before bending grooves with the minimum pitch in the direction of travel. -Enables a bending radius of 0.1mm.

以下、この発明の効果の詳細を示す。
トムソン刃１の両側の必要な位置に最小ピッチで正確な溝加工ができることにより、図５のようなコ−ナ−RのV字溝を施すことにより、図５（ｄ）のD,Eの曲げ要素間距離を短くする小さい要素間ピッチの小さいトムソン刃１曲げ加工が出来るようになる。 Details of the effects of the present invention will be described below.
By enabling accurate groove machining at a minimum pitch at the required positions on both sides of the Thomson blade 1, by applying a corner-R V-shaped groove as shown in FIG. The Thomson blade 1 can be bent with a small pitch between the small elements to shorten the distance between the bending elements.

細溝１２に対して必要な切り込み量だけ溝掘り刃物９が覗き、トムソン刃１の動きは細溝１２で規制されるのでトムソン刃１に直角方向の切り込み一定のV字溝を加工できる。細溝１２はいわば摺動可能クランプでそれが溝削り刃物と同時に動くので固定式クランプであれば切削時これが溝削り刃物と干渉するが、移動するのでそれが無く、少し長手方向に送ってからの溝加工もでき最小ピッチの溝加工ができるようになる。 The grooving blade 9 looks into the fine groove 12 by a necessary cutting amount, and the movement of the Thomson blade 1 is restricted by the fine groove 12, so that a V-shaped groove with a constant cut in the direction perpendicular to the Thomson blade 1 can be processed. Since the narrow groove 12 is a slidable clamp that moves at the same time as the grooving blade, if it is a fixed clamp, this will interfere with the grooving blade at the time of cutting, but since it moves, it will not move, and after sending it in the longitudinal direction for a while Grooving can be performed at a minimum pitch.

通常切り込みはトムソン刃１の刃厚の半分なので、１回の切り込みで溝加工は完了する。その時は、取り付け具２０、溝削り案内治具５は案内治具ベ−ス１７に固定され、溝削り刃物９を左右に動かし細溝１２より切り込み量分を覗かせ、V字溝堀案内ユニット２２を上下に動かし溝加工する。しかし数回の切り込みを必要とするときは、V字溝堀案内ユニット２２に、切り込み調整駆動部１８と送りネジ１９を付け加え、本来なら切り込みは加工ツ−ルである溝削り刃物９を動かし調整するが、溝削り刃物９を細溝１２から覗く手前で固定ネジ８を締めてつまり溝削り刃物９を固定した状態で、実際の切り込みは被加工物側のトムソン刃１を挟み込んでいる溝削り案内治具５を左右に移動させ切り込みを可能にする。 Since the normal cutting is half the thickness of the Thomson blade 1, the grooving is completed with one cutting. At that time, the fixture 20 and the grooving guide jig 5 are fixed to the guide jig base 17, and the grooving blade 9 is moved to the left and right so that the amount of cut can be seen from the narrow groove 12. 22 is moved up and down to form a groove. However, when several incisions are required, the incision adjusting drive unit 18 and the feed screw 19 are added to the V-shaped groove guide unit 22, and the incision is adjusted by moving the grooving blade 9 which is a processing tool. However, with the fixing screw 8 tightened before looking into the grooving blade 9 from the narrow groove 12, that is, with the grooving blade 9 fixed, the actual cutting is a grooving that sandwiches the Thomson blade 1 on the workpiece side. The guide jig 5 is moved to the left and right to enable cutting.

例えば、図３に於いて切り込み量は細溝１２から覗いた溝掘り刃物９によってきまるが、切り込みの無い状態つまり溝掘り刃物が細溝から覗いていない状態で左右の溝掘り刃物が移動しないように固定ネジ８で固定する。図３（ｂ）のようにV字溝掘り案内ユニット２２を右に移動させ、左側の切削準備をする。このとき溝削り案内治具５を左に少し移動させ、溝掘り刃物９を細溝１２から覗かせて切り込みし、V字溝掘り案内ユニット２２を下ろし一回目の切削を行う、その後上に上げ溝削り案内治具５を左にもう少し移動させて、次の切り込みを設定して溝加工する。同様に右側の溝を加工するときは図３（c）のようにV字溝掘り案内ユニット２２を右に移動させ、右側の切削準備をする。このとき溝削り案内治具５を右に少し移動させて切り込みし、V字溝掘り案内ユニット２２を下ろし一回目の切削を行う。その後上に上げ溝削り案内治具５を右にもう少し移動させて、次の切り込みを設定して溝加工する。 For example, in FIG. 3, the amount of cut is determined by the grooving blade 9 viewed from the narrow groove 12, but the left and right grooving blades do not move when there is no cut, that is, when the grooving blade is not viewed from the narrow groove. It is fixed with a fixing screw 8. As shown in FIG. 3B, the V-shaped grooving guide unit 22 is moved to the right to prepare for cutting on the left side. At this time, the grooving guide jig 5 is moved slightly to the left, the grooving blade 9 is looked into the narrow groove 12 and cut, the V-shaped grooving guide unit 22 is lowered, and the first cutting is performed, and then raised upward. The grooving guide jig 5 is moved a little more to the left to set the next cut and grooving. Similarly, when machining the right groove, the V-shaped groove digging guide unit 22 is moved to the right as shown in FIG. At this time, the grooving guide jig 5 is moved slightly to the right for cutting, the V-shaped grooving guide unit 22 is lowered, and the first cutting is performed. Then, the grooving guide jig 5 is moved up to the right and moved to the right a little, and the next cut is set to perform grooving.

この方法はトムソン刃１に剛性が無く、しなることができ、自動曲げ機部Aから突き出た位置でかつ、溝切り案内治具５の細溝１２の働きにより可能となる。 In this method, the Thomson blade 1 has no rigidity and can be deformed, and is enabled by the action of the narrow groove 12 of the groove cutting guide jig 5 at a position protruding from the automatic bending machine portion A.

このことにより本来なら左右二つの切り込み装置が必要とするのが一つで済みV字溝堀案内ユニット２２の軽量化がはかれる。 As a result, it is only necessary that the two cutting devices on the left and right are necessary, and the weight of the V-shaped groove guide unit 22 can be reduced.

V字溝堀案内ユニット２２は、左右一対の溝幅の異なる細溝１２の溝削り案内治具５を、取り付け具２０により脱着することにより、異なる刃厚のトムソン刃１用の溝削り案内治具５に交換出来る。 The V-shaped groove guide unit 22 detaches the groove guide jig 5 of the narrow groove 12 having a different pair of left and right groove widths by the attachment tool 20, thereby grooving guide jigs for the Thomson blade 1 having different blade thicknesses. It can be exchanged for ingredient 5.

左右移動機構部１０はV字溝堀案内ユニット２２を上下移動機構部１５に対して左右に動かせる機構である。上下移動機構部１５は、左右移動機構部１０とそれにぶら下がったV字溝堀案内ユニット２２を同時に上下させる機構である。片持ち支持部１６は
自動曲げ機部Aと上下移動機構部１５、左右移動機構部１０とV字溝堀案内ユニット２２を片持ち支持でつなげている。 The left-right movement mechanism unit 10 is a mechanism that can move the V-shaped ditch guide unit 22 left and right with respect to the up-down movement mechanism unit 15. The vertical movement mechanism unit 15 is a mechanism that simultaneously moves the horizontal movement mechanism unit 10 and the V-shaped groove guide unit 22 hung up and down at the same time. The cantilever support unit 16 connects the automatic bending machine unit A, the vertical movement mechanism unit 15, the left / right movement mechanism unit 10, and the V-shaped ditch guide unit 22 with a cantilever support.
