２図に示すようなラジェータを提案した。A type of radiator in which the end of the side bracket is soldered or brazed to the upper surface near the end of the tank body requires a multi-step soldering process to secure the above-mentioned parts, In view of the fact that the solder seals between parts that were completed in the previous soldering process are reheated due to the secondary heating that occurs during the additional Km of soldering process, and the solder tends to loosen, this improvement has been made. As an example of this, we proposed a radiator as shown in Figure 2.

ステンレス用７ラツクスを使用してはんだメッキする。By the way, when looking at the manufacturing method of the radiator 3 having a tank formed of such a tubular member, it was assembled almost according to a process chart as shown in FIG. This is a manufacturing process in which a corrosion-resistant steel material such as stainless steel is used for the tank 4.5, and welding work is included in the radiator assembly. First, for the tank 4.5, a tubular member to constitute the tank 4.5 is made in the tube making process A, and this tubular member is loaded into a mold with a cantilever structure, and burring is performed to form the tube 6. A hole for joining the water port member 12 and outlet pipe 13 is formed. Next, the tubular member is cut to a predetermined length in the cutting process C, and the both ends of the tanks 4 and 50 are machined to form welded parts of the side brackets 9 and 10, and then the accessories are hard soldered. In the outlet pipe 13 and water inlet member 12
etc., and assemble the tank subassembly by hard brazing or welding. After that, in the solder plating process E, tank 4.

, the fins 7 are assembled to the core in the assembly L step, and the side brackets 9 and 10 are fixed to this core in the welding M step. This welding is performed by resistance welding or tungsten inert gas welding. Next, the joint between the tank 4.5 and the tube 6 and the joint between the tube 6 and the fin 7 are fixed by a solder baking N process. Finally, degreasing and cleaning are performed in the cleaning O process, and the entire unit is painted in the painting P process.

法も採り得る。Note that the connection between the tank 4.5 and the side brackets 9 and 10 can also be made by hard joints, for example, if the tank 4.5 is made of brass pipes, but such a connection method is not recommended. In some cases, it is also possible to hard-braze the tank side in the tank sub-assembly process, and assemble all tanks 4, 5, tubes 6, fins 7, side brackets) 9 and 10 at once in the above assembly L process. It can be harvested.

In order to insert and support the tubular member, a mold with a cantilever structure was used and it was necessary to perform a press operation on this mold. According to this, there was a stirrup in which the holes 8 formed in the pipe member were likely to be non-uniform, resulting in undesirable results in terms of manufacturing accuracy.

The purpose is to eliminate the unevenness of burring holes to be made in the radiator tank, and to provide a radiator manufacturing method that can more reliably connect the tank and the tube, thereby solving the above-mentioned conventional problems. The goal is to solve the following problems.

構造にすることが出来る。In order to achieve the above objectives, Jishimeisha focused on making pipes for radiator tanks by bending flat plates using methods such as roll forming. The gist of this method is to form an intermediate member into a shape, apply burring to the tube joints of this member, and then bend and form the tube from a U-shaped cross section to a substantially circular shape. be. The flat plate is formed into a tank using a forming device. Since the burring process is performed on the plate material bent into a substantially U-shape at the stage where the pipe structure has not yet been formed, it is different from pressing the plate material into a normal flat plate material. Similarly, it can be placed on a die and burred. After that, the U-shaped member is bent to form a pipe, so that a tank with a pipe structure is completed, and the burring holes for connecting tubes made in this tank can have a uniform structure.

んだメッキしてタンク４．５とする。In the radiator manufacturing method according to this embodiment, the tank 4.5 is made by bending a flat plate material 31 made of a corrosion-resistant steel plate such as stainless steel into a substantially U-shaped cross section in the U-shape processing step X to form a U main member 31. Next, the KU U-shaped member 31 is subjected to a purling twist to form a burring hole 8 for joining the tube 6, and after forming the hole 8, the U-shaped member 31 is further bent in a pipe making welding step A', and approximately A tubular structure with a circular cross section is formed, the joints are welded, and the tank structure is cut to a predetermined length using the cutting C process. Then, after flaring both ends of the tanks 4 and 50 as necessary to form the welded parts of side brackets) 9 and 10, the outer Flet pipe 1 is attached in the process of hard soldering the accessories.
3, water inlet member 12, etc. are hard soldered or welded to assemble the tank subassembly, and then in the solder plating process, stainless steel black is applied to the joint part of the tube 6 of the tank 4.5, that is, around the burring hole 8. Use it and plate it with solder to make tank 4.5.

Consisting of a welding machine 24, a forming W 25, a cutting machine 26, and a product storage box I, the material is sequentially processed by sending the material from the uncoiler to the storage box I, and the tanks 4 and 5 are removed from between the plates. To manufacture. That is, in the U-shaped processing X step, the U-shaped main member 3 as shown in FIG.
Form 1. In the next process of purling, the hole 8 is formed by passing the KU-shaped member 31 in the burring press n and moving the burring press η in accordance with the feed speed of the U main member 31 to perform burring.

The U main member 31 which has been formed is put into a mold 23K and shaped so that the cross section becomes circular, and when the cross section becomes circular, a welding machine 24 applies welding 32 to the joints to create a continuous tubular structure. The shape of the tubular member is then adjusted using a mold 25 installed behind the welding machine 24.

精度が向上する。As mentioned above, in the manufacturing process of tanks 4.5, the U-shaped machining process This can be done in the same way as burring. For this reason, ψ
Because the burring process was performed by passing a mold with a cantilever structure through the tubular member, there was a difference in the amount of deflection between the tip and base of the cantilever. In contrast to the case where the dimensions of a plurality of holes provided in a row tend to be non-uniform, the present invention allows uniform holes to be formed. Therefore, when manufacturing the radiator 3, the accuracy of assembling the joint portion between the tanks 4, 5 and the tube 6 is improved.

Since the U-shaped member is burred to form holes and then formed into a tubular structure, the multiple holes opened by burring can be made uniform, improving the manufacturing accuracy of the radiator. It became possible. In addition, in the burring process, press work can be performed while moving the Q-shaped material, so there is no need to individually attach and remove the cut tubular members from the mold as in the past. A number of effects can be obtained, such as being able to shorten manufacturing time.
