W12H is the most precise and easiest to use series of 4-roll bending rolls with total pre-bending. Highly technological and innovative, W12H bending rolls assure high-productivity with a speed 3/4 times higher than a traditional pyramid bending roll. Moreover, thanks to their production methods, the W12H bending rolls can be effectively controlled through numerical control systems.
All models of Faccin's W12H 4-roll bending rolls are equipped with a rear side roll opposite the feeding side. Used as backing, this roll allows the plate to be rolled to be aligned in an immediate and accurate manner. The plate, moreover, always remains pinched between the two central rolls, thus avoiding accidental slips. This not only optimises pre-bending and rolling operations, but it also assures safer and more precise machining, with the option of being handled entirely by a single operator.
Thanks to the linear guide configuration of the W12H series bending rolls, the pre-bending operation does not require tilting the plate below the feeding level, as is the case with the traditional 3-roll bending rolls. In this way, therefore, horizontal feeding tables may be used, for easier feeding of the plate into the machine. Furthermore, there is no need to leave free space on both sides of the machines, but only at the selected infeed side.
W12H 4-roll plate bending rolls allow the plate to be rolled to the desired diameter immediately after the first pre-bending. This is followed by the second end forming, i.e. the second pre-bending. The processing method of W12H machines designed and built by Hangtian allow the cylindrical ferrule to be made in one pass.
Electronic pyramid 4-roll bending rolls make cone bending processing easier. The ability to tilt the side rolls and the central roll makes it possible to respectively set the cone angle and drag the sheet at its largest development.W12H series CNC bending rollsdesigned and built by HangTian are the best solution to bend plates of length between 1500 and 18000 mm with thickness 5 to 150 mm.
