Description
【発明の詳細な説明】 ［産業上の利用分野］ 本発明は、角パイプを溶接するために端面に開先加工を
施す開先加工装置の構成に関する。TECHNICAL FIELD The present invention relates to a configuration of a groove processing device for performing a groove processing on an end face for welding a square pipe.
［従来の技術］ 従来角パイプの端面に開先加工、すなわち端面の面取り
加工を施す場合、丸パイプと異なり外周に角があるた
め、切削用の刃を外周に沿って一様に回動させることが
困難であり、一般的には、手作業に頼っていた。[Prior Art] When a groove is formed on the end face of a conventional square pipe, that is, a chamfering process is performed on the end face, a cutting blade is uniformly rotated along the outer periphery because the outer periphery has a corner unlike a round pipe. It was difficult and generally relied on manual work.
しかしながら、大量にこの種作業がある場合は、手作業
では作業全体に時間的、また不均一な仕上がりによる信
頼性の低下といった問題を生じることがあった。However, when there is a large amount of this kind of work, there is a problem in that the manual work takes time and the reliability is deteriorated due to uneven finish.
このため、特開昭61−71908号公報に記載されるように
角パイプの角を転動する際に生じる軸向きの変位につい
て、スプリングの付勢を利用して開先刃を揺動させるこ
とによってに均一に仕上げること、および手作業の廃止
によって加工時間を短縮することが試みられている。Therefore, as described in JP-A-61-71908, for the axial displacement that occurs when rolling the corner of the square pipe, the bias of the spring is used to swing the groove blade. Have been tried to reduce the processing time by eliminating the manual work.
しかし、丸パイプと異なり角パイプの場合、外周に沿っ
て刃を回動させると径方向に角の部分と平面の部分とで
は刃の作用する位置が軸心向きに大きく変位するため、
通常のスプリングによる付勢では、押圧力に大きな変化
を生じて刃の負荷が異なることになり、仕上がりにムラ
を生じたり、スプリングの作用長を大きくすることにな
ると装置全体が大きくなって周囲の障害物に接触する機
会が増し、また、装置の構成が困難になるといった問題
を生じた。However, unlike a round pipe, in the case of a square pipe, when the blade is rotated along the outer circumference, the position where the blade acts in the radial direction in the corner portion and the plane portion is largely displaced in the axial direction,
With normal biasing by a spring, a large change in the pressing force will occur and the load on the blade will differ, resulting in uneven finish and increasing the working length of the spring. There is a problem in that the chances of contacting an obstacle increase and the configuration of the device becomes difficult.
さらに、角パイプの平面部分と角の部分とを順次転動す
る際、角の部分でスプリングが圧縮されることにより、
角の部分を転動する際の負荷が急激に大きくなり、駆動
部の出力を大きくしなければならなくなる。Further, when the flat portion and the corner portion of the square pipe are sequentially rolled, the spring is compressed at the corner portion,
The load at the time of rolling in the corner portion suddenly increases, and the output of the drive unit must be increased.
しかし、その様な方法を採用すると、開先装置全体が重
く大きくなるといった問題を生じた。However, when such a method is adopted, there arises a problem that the entire groove device is heavy and large.
［発明が解決しようとする課題］ 本発明は、この様な課題に対して、係る問題を解決して
角パイプの端面に正確に開先加工を施す開先加工装置を
提供することを目的としている。[PROBLEMS TO BE SOLVED BY THE INVENTION] An object of the present invention is to solve the above problems and to provide a groove processing apparatus for accurately performing groove processing on an end surface of a square pipe. There is.
［課題を解決するための手段］ 本発明は、角パイプの端面に沿って回動する刃を設け、
この刃と一体に移動するガイドローラを設け、このガイ
ドローラと前記刃との前記角パイプに対する軸向きの位
置関係を前記ガイドローラが前記角パイプの外周に接す
ると共に前記刃が前記角パイプの端面に切削作用を生じ

記角パイプの径方向に揺動可能に支持するように構成
し、渦巻きスプリングの渦巻き方向の伸縮を利用して前
記ガイドローラを前記角パイプに押圧付勢したことによ
って課題を解決している。[Means for Solving the Problem] The present invention provides a blade that rotates along an end surface of a square pipe,
A guide roller that moves integrally with the blade is provided, and the axial positional relationship between the guide roller and the blade with respect to the square pipe is such that the guide roller is in contact with the outer periphery of the square pipe and the blade is an end surface of the square pipe. At a position where a cutting action is generated, and further, the blade and the guide roller are supported so as to be swingable in the radial direction of the square pipe, and the guide is formed by utilizing expansion and contraction of the spiral spring in the spiral direction. The problem is solved by pressing and urging the roller against the square pipe.
［作用］ 開先加工を行う刃を角パイプの外周に沿って円滑に一定
の押圧力で揺動するように、刃の揺動を渦巻きスプリン
グによる伸縮性を利用して角パイプの外周に形成される
大きな径方向の変動に対応しており、揺動の範囲内で円
滑な付勢を行ない均一な切削を行うことができ、かつ小
形化を実現することができる。[Function] The blade is formed on the outer periphery of the square pipe by utilizing the elasticity of the spiral spring so that the blade for groove processing smoothly swings along the outer periphery of the square pipe with a constant pressing force. It is possible to cope with large fluctuations in the radial direction, perform smooth urging within the range of swinging, perform uniform cutting, and realize downsizing.
この様な渦巻きスプリングは、刃を角パイプ部に押圧す
るのに角パイプの平面部分と角の部分とで押圧方向に大
きく変位することになるが、渦巻きスプリングは、渦巻
状に形成されているため、押圧作用方向の寸法に対して
全長が長く、変位によって押圧力がほとんど変化しなく
なる。このため、ガイドローラが角パイプの角を乗り越
える時、急激に負荷が大きくなることはなく、円滑な動
作を得ることができる。Such a spiral spring is largely displaced in the pressing direction between the flat portion and the corner portion of the square pipe when the blade is pressed against the square pipe portion, but the spiral spring is formed in a spiral shape. Therefore, the overall length is longer than the dimension in the pressing action direction, and the pressing force hardly changes due to the displacement. Therefore, when the guide roller gets over the corner of the square pipe, the load does not suddenly increase and a smooth operation can be obtained.
