【発明の詳細な説明】 （産業上の利用分野） パイプの外周に沿って回動する刃を備えた開先機に関
する。DETAILED DESCRIPTION OF THE INVENTION (Industrial field of use) The present invention relates to a beveling machine having a blade that rotates along the outer circumference of a pipe.

（従来の技術） 従来この種パイプの外周に沿って回動する刃を備えた
開先機においては以下のように構成されている。(Prior Art) Conventionally, a beveling machine provided with a blade that rotates along the outer circumference of this type of pipe is configured as follows.

従来の開先機は、パイプの外周または、端部に装着さ
れ、パイプの切断または切断面の開先加工を行うもので
あり、切断または開先加工を行う刃をパイプの円周方向
に回動させパイプの中心方向に刃を移動させ切込み量を
設定している。A conventional groove machine is mounted on the outer circumference or end of a pipe and cuts the pipe or forms a groove on the cut surface.A blade for cutting or forming the groove is rotated in the circumferential direction of the pipe. The cutting depth is set by moving the blade toward the center of the pipe.

そのため、刃をパイプの中心方向に送る切込み装置と
刃をパイプの外周に沿って回動させる回動装置とが設け
られている。Therefore, a cutting device that feeds the blade toward the center of the pipe and a rotating device that rotates the blade along the outer circumference of the pipe are provided.

従来、切込み装置と回動装置は、回動量と切込み量と
の間に一定の関係、例えば回動量と切りこみ量の間に正
比例の関係を持たせ、切込み装置と回動装置が連動する

It is configured.

しかしながら、従来の開先機において、切込み装置
は、刃を切込み方向にのみ移動する機構が一般的であっ
た。However, in the conventional beveling machine, the cutting device is generally a mechanism that moves the blade only in the cutting direction.

そのため、切断または、開先加工の終了時に刃の位置
を加工開始の位置に戻すため、作業者が回動装置と切込
み装置との関連を一時的に解除し、刃を加工開始位置ま
で戻すことが行なわれている。Therefore, in order to return the position of the blade to the processing start position at the end of cutting or groove processing, the operator temporarily releases the relationship between the turning device and the cutting device and returns the blade to the processing start position. Is being carried out.

（発明が解決しようとする問題点） 以上のように、従来の開先機は切込み装置が加工終了
時に刃が自動的に加工開始の位置に戻ることがなく、繰
返しの加工を行う際には加工の終了時と開始時のいずれ
かに必ず刃の位置が加工開始の位置にあることを確認
し、刃を加工開始位置に戻すことが必要であった。(Problems to be Solved by the Invention) As described above, in the conventional beveling machine, when the cutting device does not automatically return the blade to the machining start position at the end of machining, It was necessary to confirm that the position of the blade was at the processing start position at either the end or the start of processing, and then return the blade to the processing start position.

このとき、作業者が確認を怠った場合には、刃を開先
機をパイプに装着する際に不用意にパイプに刃を当てる
等により、破損する場合がある。At this time, if the operator neglects to check, the blade may be damaged by accidentally hitting the blade on the pipe when the groove machine is attached to the pipe.

また、刃が加工終了時に開先機の内部で露出した状態
に置かれ作業者等が手内部に挿入した場合には、刃によ
って怪我を負う等の可能性があった。Further, when the blade is left exposed inside the beveling machine at the end of processing and an operator or the like inserts it inside the hand, there is a possibility that the blade may be injured.

本発明の目的は、以上のように不都合を解消し、繰返
し加工に便利にして、刃の破損および作業者の怪我の発
生等を解消した開先機を提供しようとするものである。An object of the present invention is to provide a beveling machine which eliminates the above-mentioned inconveniences, is convenient for repetitive machining, and is free from damage to the blades and the occurrence of injuries to workers.
