Product Description Folded Radiator B Tube Forming MachineI Description of folded radiator B tube forming machineThis machine is specially designed for producing folded B type radiator aluminum flat tubes.The folded tubes are produced from brazing sheet coils by a multi-step roll forming process - bringing the sheet gradually into a "B" shape. Comparing to traditional HF welded flat tubes, B-tubes have certain advantages - particularly regarding strength. The folded ends of the tube sheet are brazed inside the tube, which creates a very robust bridge between the walls. This results in higher burst pressure resistance.And thus thinner aluminum strips can be used to decrease material cost of radiator tubes.Further more, heat transferring result of radiator cores by folded B tubes is better than that of HF seam-welded tubes.Tube rolling moulds are designed in quick-changeable cassette type. By changing this kind of cassette, other size aluminum tubes can be produced as well.Of course, on same cassette, rollers can be changed for other size tubes also.This machine can 100% replace those aluminum pipe mill from Schoeler Germany, Millmaster USA or Mori Japan.Production flow:- Aluminum strip reel loading by vacuum absorber loading device (optional)- Aluminum strip decoiling by twin-head active decoiler- Aluminum strip feeding by synchronization feeder with buffer- Roll forming by 15 stations rollers, including online dimpling- Cutting to length by non-stop high speed cutter- Transmitting, with bad tube separating & collecting- Auto tube stacking system (optional)II Main features of folded radiator B tube forming machine- Servo screw pump pasting brazing flux on internal surface before forming, programmable, real-time visual inspection, assuring pasting quality and further brazing quality - Special roller designing and adjusting technology for various aluminum pipe forming- Quick roller changing, only two workers and 60 minutes to finish size changing- Perfect coordination between dimpling and cutting devices, margin length can be set freely- Dual-station tube transmitting belt, capable for separately collecting good and bad tubes- Special cutting device, supper high speed cutting catching the whole line speed, max. Cutting speed 300 tubes/min.- Dimpling and cutting are matched ideally, margin length on tube end can be freely preset- Equipped with safety barrier, protection cover, door switch and voice-light alarming- Equipped with oil mist collecting device, recovering rate >85%III Main technical data of folded radiator B tube forming machineItemDataSuitable materialPure aluminum or aluminum alloy 4343/3003/7072 or 4343/3005/7072, with claddingApplicable B tube size16~32mm x 1.4~2.5mm x 0.24~0.35mmFinished B tube outline dimension error**≤±0.05mmSuitable tube length200~1200mmApplicable aluminum strip coil sizeMax.
