It relates to a cutting device. Background art
従来より、 各種の管体をカバ一して保護するために、 ステンレス製などの金属 細線を編組した中空筒状の金属製ブレードが知られている。 このような金属製ブ レ一ドは、 第 5図に示すように、 ブレード用編組装置 1における台座 2に配備さ れている多数のボビン 3 -…から送り出されてくる金属細線 4を、 口金部 5を介し て芯金 6に巻き付けつつ筒状に編組して形成している。  BACKGROUND ART Conventionally, a hollow cylindrical metal blade formed by braiding a thin metal wire such as stainless steel has been known to cover and protect various pipes. As shown in FIG. 5, such a metal blade is used to form a thin metal wire 4 sent out from a number of bobbins 3-... It is braided into a tubular shape while being wound around the cored bar 6 via the portion 5.
このように形成された金属製ブレード 7は、 蚰線方向に対する伸縮性を有する とともに、 半径方向に対する可撓性も有しているため、 外圧による振動や荷重の 吸収性に優れた保護用ブレードであり、 自動車ゃォートバイなどの排気系におけ るチューブ類の保護用のみならず、 種々の分野に活用することができる利用価値 の高い保護体である。  Since the metal blade 7 formed in this manner has elasticity in the radial direction and flexibility in the radial direction, it is a protective blade excellent in absorbing vibration and load due to external pressure. Yes, it is a highly useful protective body that can be used not only for protection of tubes in the exhaust system of automobiles, etc., but also in various fields.

In this case, if the metal blade is cut in the empty state, the metal blade becomes flared and the cutting operation becomes difficult, and it is not possible to cut the metal blade to a predetermined length with high accuracy.
すなわち、 切断時には空出しされた中空筒状体の金属製ブレードを撩まさせず 切断しなければならず、 その切断作業に大変な手間がかかり、 量産性に劣るため 、 コス ト高になるなどの問題がある。 In other words, when cutting, the metal blade of the hollow cylindrical body that has been emptied must be cut without raising it, which requires a great deal of work and is inferior in mass productivity. There are problems such as high cost.
この発明は、 このような事情に基づいてなされたものであり、 その目的とする ところは、 ステンレス製などの金属細線を編組した中空筒状の金属製ブレードを 、 作業性よく高精度で所定長に切断することが可能な金属製ブレードの自動切断 方法、 及び、 その自動切断装置を提供することにある。 発明の開示  The present invention has been made in view of such circumstances, and an object of the present invention is to provide a hollow cylindrical metal braid formed by braiding a thin metal wire such as stainless steel with a high workability, a high precision and a predetermined length. An object of the present invention is to provide a method for automatically cutting a metal blade that can be cut into pieces, and an automatic cutting device therefor. Disclosure of the invention

以下、 この発明の実施例を図面に基づき詳細に説明する。 第 1図は、 この発明 に係る製造装置の概略構成を示す説明図である。  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is an explanatory diagram showing a schematic configuration of a manufacturing apparatus according to the present invention.
まず、 金属製ブレードは、 第 5図に示したように、 周知のブレード用編組装置 1により形成される。 すなわち、 編組装置 1の台座 2に配備された多数のボビン 3…-から送り出されてくる金属細線 4を、 口金部 5を介して芯金 6に巻き付けつ つ筒状に編組し、 中空筒体の金属製ブレード 7を形成する。  First, as shown in FIG. 5, a metal blade is formed by a well-known braid device 1 for a blade. That is, the metallic thin wire 4 sent out from the large number of bobbins 3 arranged on the pedestal 2 of the braiding device 1 is wound around the cored bar 6 via the mouthpiece 5 and braided into a cylindrical shape. The metal blade 7 is formed.
次に、 この発明に係る金属製ブレードの切断装置を、 第 1図に基づいて説明す る。 装置本体 1 0の一方側には、 固定側の芯金 1 1が配置されており、 この固定 側の芯金 1 1と対向する装置本体 1 0の他方側には、 正逆回転自在で昇降自在な ローラ 1 3 a , 1 3 aよりなる搬送手段 1 3が上下側に配備されている。  Next, an apparatus for cutting a metal blade according to the present invention will be described with reference to FIG. On one side of the apparatus main body 10, a fixed-side core metal 11 is disposed. On the other side of the apparatus main body 10 facing the fixed-side core metal 11, a forward / reverse rotatable lift is provided. Conveying means 13 composed of free rollers 13a, 13a is provided on the upper and lower sides.
固定側の芯金 1 1の外径は、 金属製ブレード 7の内径よりもやや小径に形成さ れており、 金属製ブレード 7内への揷嵌が容易になされる。 また、 固定側の芯金 1 1の先端側には、 角部が切断刃 1 1 bとされる力ップリング 1 1 aが埋め込み 型のボルト 1 1 cなどにより取付けられている。  The outer diameter of the fixed-side core metal 11 is formed to be slightly smaller than the inner diameter of the metal blade 7, so that it can be easily fitted into the metal blade 7. In addition, a force coupling 11 a having a cutting edge 11 b at the corner is attached to the distal end side of the fixed-side core metal 11 by an embedded bolt 11 c or the like.
一方、 金属製ブレード 7の始端側近傍内に揷嵌される浮芯金 1 2の外径は、 固 定側の芯金 1 1よりもやや大径に形成されており、 金属製ブレード 7内への挿嵌 が容易になされるとともに、 金属ブレード 7内で移動自在とされる。 この浮芯金 1 2の端緣は、 テーパー面部 1 2 aとされている。  On the other hand, the outer diameter of the floating core 12 fitted into the vicinity of the starting end side of the metal blade 7 is formed to be slightly larger than the core metal 11 on the fixed side. Insertion into the metal blade 7 is facilitated, and the metal blade 7 can be moved freely. An end of the floating core 12 is a tapered surface portion 12a.
また、 固定側の芯金 1 1の元部には、 固定側の芯金 1 1に被嵌された金属製ブ レ一ド 7の始端側の開口部 7 aが当接すると、 これを検出するセンサ手段 1 4が 設けられている。 このセンサ手段 1 4による検出信号は、 図示しな制御部を介し て各手段の動作を統括する。 In addition, the base of the fixed-side core 11 is fitted with a metal bracket fitted to the fixed-side core 11. A sensor means 14 for detecting when the opening 7a on the starting end side of the blade 7 comes into contact with the opening 7a is provided. The detection signal from the sensor unit 14 controls the operation of each unit via a control unit (not shown).
さらに、 固定側の芯金 1 1の元部側と先端側の近傍には舁降自在なクランプ手 段 1 5が配備されており、 固定側の芯金 1 1に被嵌された金属製ブレード 7を押 圧し固定側の芯金 1 1に密着させる。 また、 固定側の芯金 1 1の先端側には、 金 厲製ブレード 7を切断するブレード切断手段 1 6が配置されている。  Further, a clamp means 15 which can be carried around is provided in the vicinity of the base part and the tip side of the fixed core 11, and a metal blade fitted on the fixed core 11 is provided. Press 7 so that it is in close contact with the fixed core 11. Further, a blade cutting means 16 for cutting the metal blade 7 is arranged on the tip side of the fixed-side core metal 11.
次に、 切断動作を説明する。 まず、 第 1図に示すように、 予め形成された長尺 な中空筒状の金属製ブレード 7の始端側の開口部 7 aから、 金属製ブレード 7よ りもやや小径の筒体として形成されている浮芯金 1 2に揷嵌する。 その後、 この 金属製ブレード 7の始端側は搬送手段 1 3 , 1 3間まで揷通される。  Next, the cutting operation will be described. First, as shown in FIG. 1, a cylindrical member having a slightly smaller diameter than the metal blade 7 is formed from the opening 7a on the starting end side of the long, hollow cylindrical metal blade 7 formed in advance. Floating core 1 2 Thereafter, the starting end side of the metal blade 7 is passed through between the transfer means 13 and 13.
搬送手段 1 3 , 1 3間に浮芯金 1 2を揷嵌した金属製ブレード 7の始端側 7 a が揷通されると、 搬送手段 1 3 , 1 3が下降して金属製ブレード 7を浮芯金 1 2 に押圧して密着し、 かつ正転して金属製ブレード 7をその始端側の開口部 7 aよ り順次固定側の芯金 1 1に被嵌するように送り出す （第 2図参照） 。  When the starting end 7a of the metal blade 7 in which the floating core 12 is fitted between the transporting means 13 and 13 passes through, the transporting means 13 and 13 descend to move the metal blade 7 down. The metal blade 7 is pressed against and adheres to the floating core 12, rotates forward, and is sent out from the opening 7 a on the starting end side so as to be fitted to the core 11 on the fixed side sequentially (second See figure).
この際、 浮芯金 1 2は固定側の芯金 1 1 と当接されるので、 金属製ブレード 7 のみが順次固定側の芯金 1 1へと被嵌されていく。  At this time, since the floating core 12 is in contact with the fixed core 11, only the metal blade 7 is sequentially fitted to the fixed core 11.
固定側の芯金 1 1の元部にまで金属製ブレード 7の始端側の開口部 7 aが完全 に被嵌されると、 金属製ブレード 7の始端側の開口部 7 aはセンサ手段 1 4に当 接され、 その検出信号に基づき搬送手段 1 3の送り動作が停止される。 同時に、 第 3図に示したように、 芯金 1 1の元部側のクランプ手段 1 5が下降し、 固定側 の芯金 1 1に被嵌された金属製ブレード 7を押圧して芯金 1 1に固定させる。 しかる後、 搬送手段 1 3 , 1 3が逆転して金属製ブレード 7を固定側の芯金 1 1 と反対方向に牽引する （第 3図中の A→B ) 。 これにより、 金属製ブレード 7 は芯金 1 1に密着されることとなる。 少なく とも、 この箇所の金属製ブレード 7 は外力によっては撩まない状態とされる。  When the opening 7a on the starting end of the metal blade 7 is completely fitted to the base of the fixed-side core metal 11, the opening 7 a on the starting end of the metal blade 7 becomes the sensor means 14. And the feeding operation of the transport means 13 is stopped based on the detection signal. At the same time, as shown in FIG. 3, the clamping means 15 on the base side of the core 11 descends and presses the metal blade 7 fitted on the fixed-side core 11 to press the core. 1 Fix it to 1. Thereafter, the transporting means 13 and 13 are reversed to pull the metal blade 7 in the opposite direction to the fixed-side core metal 11 (A → B in FIG. 3). As a result, the metal blade 7 comes into close contact with the core 11. At least, the metal blade 7 at this point is not fluttered by external force.
次いで、 第 4図に示したように、 芯金 1 1の先端部側のクランプ手段 1 5が下 降して金属製ブレード 7を押圧し、 所定長が確保されて固定側の芯金 1 1に密着 し、 浮芯金 1 2と搬送手段 1 3 , 1 3により牽引状態にある金属ブレード 7に対 し、 ブレード切断手段 1 6が瞬時に切断を行う。 Next, as shown in FIG. 4, the clamping means 15 on the distal end side of the cored bar 11 is lowered. Then, the metal blade 7 is pressed down, and a predetermined length is secured.The metal blade 7 comes into close contact with the fixed-side metal core 11, and is pulled by the floating metal core 12 and the transporting means 13, 13 to the metal blade 7 in a towed state. On the other hand, the blade cutting means 16 cuts instantaneously.
切断後には、 搬送手段 1 3 , 1 3が固定側の芯金 1 1よりも離れるように移動 され、 固定側の芯金 1 1に被嵌されている所定長に切断された金属製ブレード 7 を取り外す。 その後、 上記 ί力作を繰り返し所定長の金属製ブレード 7の量産を行 このように、 この実施例によれば、 ステンレス製などの金属細線を編組した中 空筒状の金属製ブレードを所定長に切断する際には、 金属製ブレ一ド内に 2つの 芯金を相対向するように揷嵌して金属製ブレードを筒状に保持するとともに、 2 つの芯金部分における金属製ブレードをそれぞれ固定しつつ相反する方向へ牽引 して芯金に密着させ、 両芯金の間隙部分において牽引状態にある金属製ブレード を切断するため、 切断時には、 切断箇所の金属製ブレードが撓むことがなく、 高 精度な所定長の金属製ブレニドを作業性よく量産することができる。  After the cutting, the transporting means 13, 13 are moved so as to be further away from the fixed-side core 11, and the metal blade 7 cut to a predetermined length fitted on the fixed-side core 11. Remove. Thereafter, the above-described operation is repeated to mass-produce the metal blade 7 having a predetermined length. Thus, according to this embodiment, the hollow cylindrical metal blade formed by braiding a thin metal wire such as stainless steel is formed into a predetermined length. When cutting, two metal cores are fitted into metal blades so that they face each other, holding the metal blades in a cylindrical shape, and fixing the metal blades on the two metal cores, respectively. While pulling, the metal blade in the towed state is cut in the gap between the two cores by pulling it in the opposite direction and bringing it into close contact with the core metal. It is possible to mass-produce a highly precise metal blenid of a predetermined length with good workability.
また、 切断時には金属ブレードのスクラップも発生せず、 所定長の金属ブレー ドを連続して自動的に得ることができるので、 製作費用のコス トダウンを図るこ とができる。  In addition, no metal blade scrap is generated at the time of cutting, and a metal blade of a predetermined length can be automatically obtained continuously, so that manufacturing costs can be reduced.
