この発明は熱交換器等に使用して好適なフイン
付管の製造方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of manufacturing a finned tube suitable for use in heat exchangers and the like.
従来のフイン付管の製造方法は、第６図および
第７図に示すように、テープ状素材１を１対の平

次いで成形材が巻付けられた管を加熱して巻付け
られた成形材と芯管との間を半田結合させて製造
していた。 As shown in FIGS. 6 and 7, the conventional method for manufacturing a finned tube involves corrugating a tape-shaped material 1 with a pair of spur gear devices 2, and then applying a guide 4 having a brake 3 at the outlet. The guide is pushed in from the inlet to reduce the pitch, and then pulled out sequentially from the guide outlet and wound spirally around the outer periphery of the core tube 5, which has been previously wrapped with solder tape 6.
Next, the tube wrapped with the molded material is heated and the wrapped molded material and the core tube are soldered together.
かゝる従来の製造方法は、ピツチが縮められた
成形材をガイド４の出口から引出して芯管５の外
周に巻付けるものであるから、その巻付けに際し
ては、ピツチが復元しない程度の非常に低い張力
下で成形材を芯管５に巻付けねばならず、甚だ非
能率であつた。 In such a conventional manufacturing method, the molded material whose pitch has been reduced is pulled out from the outlet of the guide 4 and wrapped around the outer circumference of the core tube 5. Therefore, when winding the material, care must be taken to prevent the pitch from recovering. The molded material had to be wound around the core tube 5 under low tension, which was extremely inefficient.
又、ガイド４の出口から引出される成形材の速

なり、全体として生産性が低く、コスト高となる
等の問題があつた。 Furthermore, since the speed of the molded material being pulled out from the outlet of the guide 4 is slow, the speed at which the tape-shaped material is pushed in by the spur gear device 2 is also inevitably limited, resulting in low productivity and high cost as a whole. There were problems such as high temperatures.

したフイン付管の製造方法である。 In order to solve these problems, the applicant previously proposed a method of manufacturing a finned tube as shown in FIGS. 1 and 2. This is a molding device consisting of a die rotating body 12 having a plurality of pins 26 annularly implanted on the side end surface, and a press die rotating body 11 having at least two press dies 20a, 20b on its outer periphery.
The tape-shaped material 1 disposed around the core pipe P and wound around the pin 26 is formed into a wave shape by the pushing operation of the press molds 20a and 20b, and then the forming device and the core pipe P are intermittent. In this method of manufacturing a finned tube, a molding material is wound around a core tube P by rotation and relative intermittent movement of a molding device in the core tube axis direction, and then heated and soldered.
しかして前記発明の実用化に際してなお解決す
べき問題がある。それは成形材を芯管Ｐに巻付け
る際、成形材のスプリングバツク現象により成形
材と芯管Ｐとの接触が悪く、引続いて行われる半
田付けが確実にできにくいことである。 However, there are still problems to be solved when the invention is put into practical use. This is because when the molded material is wound around the core tube P, the contact between the molded material and the core tube P is poor due to the springback phenomenon of the molded material, making it difficult to perform the subsequent soldering reliably.
この発明はこうした問題点を解消して能率よく
フイン付管を製造しようとするものである。 The present invention aims to solve these problems and efficiently manufacture a finned tube.
以下、図面に示した実施例について説明する。 The embodiments shown in the drawings will be described below.

0' guide groove, 22 is cylinder 19b
24 is a positioning stopper for the cylinder 19b, 25 is a guide groove cut into the side end surface of the mold rotor 12, and the adjacent guide grooves 25 Between them, a pin 26 is provided in an annular manner protruding from the end of the guide groove toward the center of rotation for receiving the tape-shaped material 1 pressed and bent by the press dies 20a and 20b.

１′自体が、芯管Ｐに対し、巻締現象を起すよう
に巻付けられるようにした点に特徴がある。 The molding device configured in this way is the same as the one previously proposed by the applicant, but the tape material 1 unwound from the reel is wound around the pin 26, and its tip is clamped to the core tube P. Then, after pressing and bending the tape-like material 1 on the pin 26 sequentially with the press dies 20a and 20b, the forming device and the core pipe P are connected while the press dies 20a and 20b hold the tape-like material in the pressed and bent state.
and are rotated in the direction in which the tape-like material 1 is wound around the pin 26 by a drive device (not shown), but in this case, the rotation of the core tube P is controlled as shown in FIGS. 4 and 5. The angle θ 2 is the rotation angle of the forming device θ 1
(in the example, it is 30 degrees), for example, about 31 degrees, so that the formed material 1' itself wrapped around the core tube P causes a tightening phenomenon. It is distinctive in that it allows for

20b outward from the pin 26, and remove the tension spring 2.
The cylinder 19a is returned to its original position with the tensile force No. 2, and at this return position, the same operation as described above is performed to release the cylinder 19a.
The press die 20a is pressed into the molded part formed by the press die 20b in the previous step to hold the molded material. Thereafter, the molding operation is continued by repeating the above operations.

できる。 When the molded material 1' formed in this way is wrapped around the core pipe P, the winding action generated in the molded material effectively brings the molded material 1' into contact with the core tube P.
With the relative intermittent movement of the forming device placed on the core tube in the axial direction of the core tube, the heating device 28 heats the forming material during the wrapping process, making it possible to perform reliable soldering. It can be manufactured efficiently.
