のものが使用されている。 Figure 1 shows a cross section of the radiator. Hot water to be cooled enters the upper tank 2 from the inlet pipe 1, passes through the tube 3, cools by radiating heat into the air from the fins 4, and flows into the lower tank 5. After entering, it flows out from the outlet pipe 6. Generally, in this type of heat exchanger such as a radiator, a turbulator 7 may be inserted into the tube 3 as shown in FIG. 1 in order to effectively transfer heat through the tube 3. The shape of the turbulent element 7 is usually a wave-like shape in which bulges 8 in opposite directions are formed alternately on the left and right sides of the width of the strip by pressing a thin metal as shown in Fig. 2 A to D. is used.

厚みが薄くなつて剛性が弱くなると云う不都合が
生じる。 This invention relates to the manufacture of the turbulent flow element 7 having the above-mentioned shape. Conventionally, the turbulence element 7 is manufactured by machining the turbulator 7 one by one starting from the end, or by machining a certain pitch of crests at the same time. However, if the former is manufactured by machining one mountain at a time from the edge, the work efficiency is very poor and productivity is low, while the latter is manufactured by machining a certain pitch of mountain at the same time. Although productivity can be increased, when a large number of ridges are processed at the same time, there are disadvantages in that the material is stretched and cut, or stretched and becomes thinner and less rigid.

It is an object of the present invention to provide an apparatus for producing a turbulent flow element for a heat exchanger.

７に切断されて製品として取り出される。 The material 15 is in the form of a long and narrow strip and is continuously wound onto the reel 9. The material 15 fed out from the reel 9 passes through a leveler 10, where it is smoothed and fed into a feeding mechanism 11. Feeding mechanism 11
1 is used to feed the material 15 to the mold 12 by a fixed length, and the material 1 is fed by closing the pair of clamping claws 16, 16.
5 is held, and even in this state, the holding claws 1
6 and 16 are moved laterally to feed the material 15 a fixed length. The amount of feed of the material 15 by the feed mechanism 11 at this time is set to be the length (l+l 1 ) obtained by adding the shrinkage l 1 due to forming to the dimension l after the forming process, as shown in FIG. The forming mold 12 is designed to be able to process a certain pitch of ridges, for example, nine ridges in the embodiment shown in the drawings. As shown in FIG. 5, this molding die 12 has a plurality of sets of dies aligned in the direction of movement of the material, and each set consists of a pair of dies lined up horizontally when viewed from the direction of movement of the material, each with a cam. By being driven by the material, the substantially center in the width direction of the material is turned upside down and both sides of the material are bulged out in opposite directions. That is, type A, type B, type C, type D, type E, type B',
It consists of nine molds each divided into C' type, D' type and E' type, each having one mountain.The central type A is first operated by cams 17, 17, and then the front and rear of the A type are operated. The arranged B types and B' types are activated, followed by C types and C' types → D types and D' types → E types and E' types. Therefore, the material 15 fed into the molding die 12 is molded into the A-type with the central peak first, and thereafter is simultaneously molded into B-type, B'-type, C-type, and C-type, two peaks at a time in the front and rear directions. ', D, D', E and E' types are formed in sequence, and the processing is completed when a total of 9 ridges are formed. Molding mold 1
The material 15 with the peaks formed in step 2 is cut into turbulators 7 of a predetermined length by a product length feeder 13 and a cutting device 14, and taken out as a product.

２山づつ加工する為、加工速度が速くて生産性を
高めることができる。 With the apparatus for manufacturing turbulence elements for heat exchangers of this invention, the material is not pulled and cut because it is processed one by one, and the material is fed by taking into account shrinkage. Therefore, the rigidity of the turbulator can be maintained without being stretched and thinned. In addition, the apparatus of the present invention feeds a certain length of material into the mold at once and processes two ridges from the center forward and backward at the same time, so the processing speed is fast and productivity can be increased.

加工することができる。 In addition, in the above explanation, the mold with one ridge was explained for mold 1, but it is possible to provide two or three ridges in mold 1 as long as the material is not cut or the thickness is not reduced. By providing a ridge or three ridges, the machining speed can be increased and productivity can be increased accordingly.
Furthermore, with the apparatus of the present invention, even a shape as shown in FIG. 6 can be processed accurately and without reducing the thickness.

性が著しく向上するという特長を有している。 As explained above, the present invention includes a reel wound with a continuous long and thin strip of material, a leveler for smoothing the material fed from the reel, and a material after being smoothed by the leveler. A feeding mechanism that feeds the material by a length equal to the dimension after forming plus the shrinkage due to forming, and a feeding mechanism that feeds the material for a certain pitch in the front and back direction from the center of the length. A mold that processes the same number of peaks at the same time at different times, and a product length feeder and cutting device that cuts the material processed by the mold into a predetermined length to produce the product. and the forming die has a plurality of sets of dies aligned in the direction of movement of the material, each set consisting of a pair of dies arranged side by side when viewed from the direction of movement of the material, each set being driven by a cam. By doing so, the approximately center of the material in the width direction is turned upside down and both sides of the material are bulged out to opposite sides, so the material will not be stretched and cut, or stretched and thinned. The rigidity of the turbulent can be maintained by
It has the advantage of high work efficiency and faster machining speed, which significantly improves productivity.
