本発明は、管材に長手方向の溝部を形成する方法に関す
るもめで、その目的とするところは、多種多様な溝部を
持つ管材を容易に且つ廉価する事にある。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of forming longitudinal grooves in a tube, and its purpose is to easily and inexpensively produce tubes having a wide variety of grooves.
従来、管材に長手方向の溝を施す場合は、プレス加工が

シ難かしさを伴っていた。本発明は、以主のような点に
鑑み鋭意工夫を施したものである。Conventionally, when creating longitudinal grooves in pipe materials, press working has been considered, but with the press method, a female mold, etc. must be loaded inside the pipe material, and equipment corresponding to the diameter and length of the pipe material is required. Pressing is not suitable for tubes with stepped sections or tapered ends, and when forming long grooves, there are problems with uniformity of pressing. It was accompanied by some difficulty. The present invention has been devised in consideration of the following points.

る。The forming roller (2) is rotatable and movable back and forth and left and right. The forming roller (2) is provided so that the central axis (A) of the material tube (1) lies on its rotating surface. That is, they are provided so as to be positioned radially with respect to the central axis (A). The number of forming rollers (2) to be installed is not limited to the side stages, and may be one as shown in FIGS.
When performing (3)..., the number of forming rollers (2) may be increased to 2.14 as shown in Fig. 3.4.5. However, many grooves (3) (3)...

(3) It is not necessary to arrange the number of grooves (3) around the material tube (1), for example, when forming 12 grooves (3) around the material pipe (1), use the forming roller (2) as shown in Figure 4. If six pieces are provided, the purpose can be achieved by sequentially rotating the material tube (1) by 50 degrees. Of course, the forming roller (2)
It is also possible to rotate the material around the material tube (1).

溝形成が行なえる。When forming the groove portion (3), the forming roller (2) is caused to run while pressing against a predetermined position of the material tube (1). The process involves a process in which the groove (3) is initially shallow and gradually deepens, depending on the depth k of the groove (3), that is, the forming roller (2) moves forward (towards the center of the material tube (1)), By repeating the process of running (parallel to the axis (B)) several times, it was possible to avoid a decrease in wall thickness in the groove (3) or its surroundings, and the finished condition was also good. Numerous grooves (3) (3) around (1)...
In the case of forming ..., rather than completing the groove (3) partially around the material tube (1), it is necessary to form the groove (3) evenly around the circumference, that is, each groove (3) (3)... It is better to form grooves (3) (3) around the entire circumference while sequentially rotating the material tube (1) at an appropriate angle from a shallow state to a deep state, so that the material tube does not deform. In addition, the wall thickness was uniform and a good grooved tube was obtained. In the present invention, as described above, the grooves are formed by pressing the rotatable forming roller against the material tube and running it in the longitudinal direction. It is also possible to form a long groove, and even when the material tube has a step (4) as shown in Fig. 3, it is not necessary to load a female die as in press working. Since there are no holes, grooves can be easily formed without being affected by the shape of the material tube.
つまり、段（波形）や長手方向の溝などが混った管材が
成形出来る。In other words, it is possible to form pipes with a mixture of steps (waveforms) and longitudinal grooves.
素材管の周囲の溝数の変更も素材管の回転角度の変更程
度で済むため簡単どなり又、成形ローラーが前後方向に
移動が可能であるので素材管の径の大小にも充分対応出
来、多種多様な溝付の管材を提供出来ることになる。Changing the number of grooves around the material tube is as easy as changing the rotation angle of the material tube, and since the forming roller can move back and forth, it can be used to accommodate large and small diameters of the material tube, making it suitable for a wide variety of types. This means that we can provide a wide variety of grooved pipe materials.
