溝加工を施している。For example, in order to reduce NOx in a gas turbine combustor, it is necessary to use a tapered cone inside the liner, and the outer circumference of the cone is grooved to withstand thermal stress. .
そこで、テーパ円筒体の周壁外周面に溝を加工する従来

第１図に示すような、テーパ円筒体１の周壁外周に溝部
１ａを加工する方法としては、まず一般的に第２，３図
に示す方法が用いられている。As a method for forming the groove 1a on the outer periphery of the peripheral wall of the tapered cylindrical body 1 as shown in FIG. 1, the methods shown in FIGS. 2 and 3 are generally used.

工用ローラ３を押しつけ、前記金型２の溝部２ａに、テ
ーパ円筒体１の周壁を倣い変形させることによって所要
の溝１ａを形成する。A tapered mold 2 is fitted onto the inner surface of the tapered cylindrical body 1,
The mold 2 having the groove 2a is rotated in the direction of the arrow by the power of a lathe or the like (not shown), and the processing roller 3 is pressed from the outer peripheral side of the tapered cylindrical body 1 to form the taper into the groove 2a of the mold 2. A required groove 1a is formed by tracing and deforming the peripheral wall of the cylindrical body 1.
しかし、この方法では、第３図に示すように、溝１ａの

テーパ状の金型を用いた方法である。A method for forming grooves on the outer circumferential surface of a peripheral wall of a tapered cylindrical body according to the present invention includes inserting a rotating mold having grooves formed in advance inside the tapered cylindrical body, and pressing and supporting both ends of the tapered cylindrical body while , the outer circumferential surface of the tapered cylindrical body is pressed against the mold by a processing roller, and the circumferential wall of the tapered cylindrical body is deformed by following the groove of the mold to form a desired groove; In the groove machining method, the mold has a taper with a ridgeline length equal to the ridgeline length of the tapered cylindrical body, and the number of rotations at both ends of the tapered cylindrical body is made equal to the number of rotations at both ends of the mold. This method uses a tapered mold configured as follows.
なお、本発明を開発した考え方を付記すると、次のとお

加工中にテーパ円筒体が移動し、溝加工ができないとい
う欠点がある。Among the methods of forming grooves on the outer periphery of the tapered cylindrical body shown in Figs. 2 to 4, the simplest and cheapest method is the processing method shown in Fig. 4. Because the rotation speed in the axial direction is different at the contact point of the mold,
The disadvantage is that the tapered cylindrical body moves during machining, making it impossible to perform groove machining.

が適している。Therefore, we devised a method that would prevent the tapered cylindrical body from moving in the axial direction during processing. Specifically, this is a method of making the rotational speed of the tapered cylindrical body and the mold the same at both ends of the tapered cylindrical body, and for this purpose, the processing method using the mold according to the present invention is suitable.

ことによって所要の溝を形成せしめる。A tapered mold 12 is inserted into the inner surface of the tapered cylindrical body 1, and the mold 12 is rotated by the power of a lathe (not shown), etc., and the guide rollers 4
The processing roller 3 is pressed from the outer circumferential side of the tapered cylindrical body 11 while pressing and supporting it, and the peripheral wall of the tapered cylindrical body 11 is deformed by tracing the groove 12a of the mold 12, thereby forming a required groove. .

テーパ状の金型１２を用いる心安があり、そのためには
次の条件を備えた金型を用いれば良い。In this way, in order to groove the outer circumferential surface of the peripheral wall of the tapered cylindrical body 11 using the rotating mold 12 and the processing roller 3, it is necessary to create a groove so that the tapered cylindrical body 11 and the mold can roll without slipping. There is no need to worry about using a mold 12 with a shape, and for that purpose, a mold that meets the following conditions may be used.
