In order to accommodate this, it is necessary to prepare a large number of specialized devices with different diameters and to replace them, which is extremely uneconomical due to high initial cost, and requires a lot of effort to replace. This had the disadvantage of reducing work efficiency.

位置変更及び固定自在に構成しであることを特徴とする
。In order to achieve the above-mentioned purpose, the pipe end forming apparatus of the present invention has a fixing member fixedly positioned relative to the pipe to be processed, while rotating around an axis corresponding to the center of the pipe to be processed. A rotating member is provided so as to be movable in a direction along the rotational axis, and the rotating member is provided with first and λ-shaped surfaces at different positions in the direction along the rotational axis, and 1. A forming member is displaced along the entire circumference of the end while contacting the inner circumferential surface of the pipe to be processed; It is characterized in that it is configured to be able to be freely changed in position and fixed to a second position where the third conical surface is applied by entering the pipe.

のである。In other words, when flaring as described in (a) above, the conical first forming member is fixed at the first position and moved in the direction of the rotation axis, and the first forming member is moved to the end of the pipe to be processed. It acts over the entire circumference of the tube, pushing the end of the tube into a trumpet-like shape.

加工の際には、上述(ハ)の場合と同じ第1成形而によ
り、その固定すべき第1位置を適宜変更し、同様の作用
により管の端部を拡大するのである。In the above-mentioned (b) punching process, after the above-mentioned flaring process, the first molding surface is displaced and fixed in the second position, and in that state, while moving in the direction of the rotation axis, it is pushed out into a trumpet shape. The second and second forming members perpendicular to the rotational axis are applied to the pipe end portion thus formed, thereby forming a flange portion perpendicular to the rotational axis. When machining the perfect circle as shown in e→ above, the first shape is provided with a conical tip and a cylindrical surface as a whole, and the first forming surface is rotated while being fixed at the first position. While moving in the axial direction, the first Fft-shaped surface acts on the inner circumferential surface of the pipe to be processed over the entire circumference of the end, thereby making the end of the pipe perfectly circular. Then, during the tube expansion process described in (a) above, the first position to be fixed is appropriately changed by the same first forming process as in the case (c) above, and the end of the tube is expanded by the same action. It is.
上記作用による効果は次の通りである。The effects of the above action are as follows.

えるようになった。In other words, by simply displacing the first molding surface in the direction intersecting the rotation axis, and changing the fixed position from the ¥J/ position to the fifth position, one flange can be removed without any replacement operation. Processing can be easily performed, and when switching from round processing to tube expansion processing, etc., the first position where the first forming surface acts on the tube end itself is h, and the fixed position is changed to the multi-piece position. With K, it is possible to process both a perfect circle and a tube expansion using the same first forming process without replacing with different parts, and it can be easily handled even if the diameter of the pipe to be processed is different. By moving the first FR cedar surface along the entire circumference of the end of the pipe at a position offset from the rotational axis of the rotating member, various forming processes on the end of the pipe can be performed using the apparatus. By simply replacing some of the molding tools while still using most of them, the initial cost is low and the process can be carried out efficiently.
