向」―させるために熱交換器ショップのFA化(工場の
自動化)を強力に推進する必要がある。The cross-fin type heat exchanger is generally manufactured by the following method. A large number of pipe insertion holes are formed in a thin aluminum plate using a press mold, and the desired product width is continuously cut into 11 widths, followed by cutting to an appropriate fin length to produce fins. After stacking a large number of these fins and inserting the 0-shaped pipe into the pipe insertion hole of the fin, push the tube expansion head into the 0-shaped pipe to expand the pipe diameter and fix the fin and pipe.
Furthermore, without washing this heat exchanger, a successor vibrator is brazed to complete the heat exchanger. As described above, the loss fin type heat exchanger is the best in terms of production method, cost, etc. compared to other heat exchangers, but in order to further improve price competitiveness, we have developed a heat exchanger shop. It is necessary to strongly promote FA (factory automation).

あった。Conventional automation mainly relied on specialized equipment, so when changing product specifications, major equipment modifications were required, or the equipment could become completely unusable.
The drawback was that it was difficult to respond to diversifying market needs.

ことにある。An object of the present invention is to assemble a collective heat exchanger consisting of a plurality of heat exchangers assembled in the width direction, and then cut and separate a part of the fins to produce a plurality of heat exchangers. The purpose of the present invention is to provide a method for manufacturing a heat exchanger that is highly productive and flexible enough to accommodate diversification of product specifications.

フィンの支持方法は、フィンの両サイドをガイド板で案
内支持する構造であり、特に熱交換器列数の少ない細幅
リボン状フィンの場合に本方法は有効である。The present invention has been made with attention to the following points. Over the past few years, heat pump room air conditioners with both cooling and heating functions have become more economical than other heating devices due to their heating capacity, and their safety has been compromised due to their cleanliness. The number of installed units is rapidly increasing, and the penetration rate of room air conditioners as a whole is increasing. On the other hand, due to the diversification of product needs and the reduction of work in progress, production lots have recently become smaller, increasing setup time and associated adjustment time for room air conditioner heat exchanger production equipment, reducing production efficiency. I'm letting you do it.・On the other hand, regarding automatic assembly of fins and pipes with high productivity, a large number of pipe insertion holes are formed in a thin aluminum plate using a press mold, and the width is continuously cut to the desired product width to form a multi-row ribbon shape. After manufacturing the fins, the above ribbon-shaped fins were pulled out of the mold and twisted and slackened while widening the distance between the ribbons.Then, cutting the fins to an appropriate length, cutting the fins to a diameter slightly larger than the pipe insertion hole of the fins. A method has been proposed in which the 111ffi fins are stacked while being pushed into a small stacking bar, and then a pipe is automatically inserted into the stacked fins. (Utility Model Application No. 55-103032) Note that the method of supporting ribbon-shaped fins with wide spacing up to the position where they are pushed into the stacking bar is a structure in which both sides of the fins are guided and supported by guide plates. This method is effective in the case of narrow ribbon-like fins with a small number of rows.
この様にフィンの両サイドを案内支持する構造であると
、リボン状フィンに前工程で発生した歪があってフィン
が曲がった状態で送られても、ガイド板により正確な位
置決めができるため、スタッキングバーへのフィンの押
込みを確実なものにする。With this structure that guides and supports both sides of the fin, even if the ribbon-shaped fin is fed in a bent state due to distortion caused in the previous process, the guide plate allows accurate positioning. To ensure that fins are pushed into a stacking bar.
寸だ、フィンを押込むスタッキングバーの直径をフィン
のパイプ挿入孔よりわずか小さくすることにより、積み
重ねたフィンのパイプ挿入孔の位1、/7すれ\を防止
でき、次工程でのパイプ挿入性が向上してパイプ挿入の
自動化が図れる。By making the diameter of the stacking bar into which the fins are pushed slightly smaller than the pipe insertion hole of the fin, it is possible to prevent the pipe insertion hole of the stacked fins from rubbing against each other by 1/7 inch, making it easier to insert the pipe in the next process. This improves the performance and allows automation of pipe insertion.
このように幅方向でフィンをガイドしてフィンスタッキ

、雇のスタッキングバーの位置、パイプ挿入装置等の大
幅な改造が必要となる。This method of guiding the fins in the width direction and forcing the fins into the stacking bar of the fin stacker using the guide plate allows thin plate fins to be stacked reliably, and also allows for automatic pipe insertion. Since it is easy to use, highly reliable automation can be achieved, reducing man-hours and improving equipment operating rate. However, since this method has a structure that guides both sides of the fin, it can only accommodate one type of fin width, and when the fin width changes, the fin guide plate, the position of the stacking bar, the pipe insertion device etc. A major modification will be required.

方法である。The present invention provides a method for manufacturing a heat exchanger that does not require setup of a fin pipe assembly device and is highly flexible when changing the product fin width, and is a very useful method.
以下本発明の一実施例を第1図から第4図で説明する。 An embodiment of the present invention will be described below with reference to FIGS. 1 to 4.

幅フィンを連続的に幅切断して行く。In Fig. 1, a number of pipe insertion holes 2 are first formed on a thin aluminum plate 1 with a thickness of 0.1 to 0.15m+n, and then a width cutting cutting blade A3 is formed.
A width cutting unit equipped with a width cutting cutting blade B4 and a width cutting cutting blade B4 continuously cut the width of wide fins that are sequentially fed to a fixed length by a fin feeding unit (not shown).

切断線6を任意のフィン長さで形成することができる。With and It forms 6,
In the case of the width cutting blade A6, it is sufficient to continuously operate the width cutting blade A3, which is set so that the engagement length of the cutting blade is slightly longer than the fixed feed length of the fin. -Blade width cutting blade B4
In the case of , for example, the width cutting cutting blade B 4 is a cutting blade that does not have both corners of the upper blade so that when the fin is cut to length in the later process, uncut parts 7 are formed at both ends of the width cutting line B. For the first and last cuts from the length cutting position, the engagement depth of the width cutting blade 134 is made shallow, and for other than the above width cutting, the engagement depth of the width cutting blade 134 is deepened to leave an edge. A cutting line 6 having a certain width can be formed with an arbitrary fin length.

6の両側に設けても、寸だ片側だけに設けてもよい。The engagement depth of the width cutting blade 134 can be controlled by operating a cylinder or the like built into the two plates of the width cutting unit. Note that the uncut portions 7 may be provided on both sides of the edge remaining width cutting line 6, or may be provided only on one side.

更により、1列熱交換器を6個又は5列熱交換器を2個
同時に製作することができる。In this embodiment, the manufacturing method of the set fin 9 is described in which five two-row heat exchangers are manufactured by lining up five pieces in the width direction at the same time, but the mounting position of the width cutting blade A3 and the width cutting blade B4 is changed. Accordingly, six single-row heat exchangers or two five-row heat exchangers can be manufactured at the same time.
集合フィンの列数は幾列でも良いが、例えば実施例の2

フィンとなる。The number of rows of collective fins may be any number, but for example, in the second embodiment,
If we use a 12-row assembly fin that has double the number of rows, it will become a flexible assembly fin that can accommodate four types of heat exchangers with 1 to 4 rows.

4が容易に自動挿入できる。The fins formed with the continuous width cutting line 5 and the edge remaining width cutting line 6 in this way are not bent compared to the conventional fins that are cut to the required width from the beginning, so the length cutting blade 8 is used to cut the fins to the desired length. It becomes easy to stack a large number of fins one after another on the stacking bar 10 without having to cut them into pieces. To stack the fins, the fins protruding from the length cutting cutting blade 8 are adsorbed to the fin suction machine by the 7-year suction unit and the desired fin length is obtained. After cutting the fin with the length cutting cutting blade 8, the fin suction plate is pushed while the fin is suctioned, and the fin is forcibly inserted into the stacking par 10, which has a diameter slightly smaller than the pipe insertion hole 2 of the fin. The heat exchanger for a general room air conditioner has an outer diameter of 9.6r.
