本発明は、パイプを素材として、バルジ加工により、熱
交換器用のタンク（以下単にタンクという）を製造する
方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a method for manufacturing a tank for a heat exchanger (hereinafter simply referred to as a tank) by bulging a pipe as a material.
従来より、タンクは、プレス加工により、板材より成形
したタンク本体の取付孔に、流体の出入口となる短寸の
パイプを溶接するか、またはかしめて取り付けた後、ろ
う付けして製作していた。Conventionally, tanks have been manufactured by welding or caulking short pipes, which serve as fluid inlets and outlets, into the mounting holes in the tank body, which is formed from plate material using press processing, and then brazing the pipes. .
そのため、製造工程数が多くなり、手間がかかった。ま
た、加工に伴う応力が残存し、かつ短寸のパイプの接続
部における流路抵抗が大であった。Therefore, the number of manufacturing steps was increased and it was time-consuming. In addition, stress due to processing remained, and flow path resistance at the connection portion of the short pipe was large.
本発明は、パイプの中間要所部を、バルジ加工により膨
出させた後、この両端の未膨出部を含まない切断面をも
って、前記膨出部を２分割することにより、上述の問題
点の解決を図ったものである。The present invention solves the above-mentioned problem by bulging the middle important part of the pipe by bulging process, and then dividing the bulging part into two with a cut surface that does not include the unbulged parts at both ends. This is an attempt to solve the problem.
本発明によれば、パイプの中間部のバルジ加工による膨
出部を２分割することにより、膨出部に連続するパイプ
の端部がそのまま流体の出入口となるタンクが２個得ら
れる。According to the present invention, by dividing the bulging portion formed by bulging the intermediate portion of the pipe into two, two tanks can be obtained in which the end portion of the pipe that is continuous with the bulging portion serves as an inlet and an inlet for fluid.

中間体（４）を形成する。FIGS. 1 to 4 show the method of the present invention in the order of steps. As shown in FIG. By bulging the central part of pipe (1) using water pressure or hydraulic pressure, the axis (Y-Y) of pipe (1) is aligned with both ends (2) of pipe (1) remaining, as shown in Figure 2. ) includes a cylindrical bulge (3) obliquely intersecting the axis (X-X) of the first
Form intermediate (4).
ついで、第１中間体（４）の膨出部（３）を、第２図に

うに、それぞれが端部（２）を１個有する。同形同寸の
第２中間体（６）が２個得られる。Next, as shown in FIG. 2, the bulging part (3) of the first intermediate body (4) is divided into two parts by holding the dividing plane (Z-Z) that does not pass through the unbulging both ends (2). When divided, each part has one end (2), as shown in FIG. Two second intermediates (6) of the same shape and size are obtained.

曲面をなしているので、通過抵抗は小さい。As mentioned above, according to the method of the present invention, a tank is obtained in which the fluid inlet and outlet are inherently connected, so the manufacture of the tank is significantly simplified, and the inner surface of the fluid inlet and outlet forms a continuous curved surface. Therefore, the passing resistance is small.
