The 4HEL bending series from Faccin (Visano, Italy) is a precise and easy to use 4-roll bender with total pre-bending and can be controlled with numerical control systems. The 4HEL series is ideal for bending plates between 1,500 mm and 18,000 mm with a thickness from 5 mm to 150 mm.
All models of the 4HEL are equipped with a rear side roll opposite the feeding side. Used as a backing, this roll allows the plate to be rolled and aligned in an immediate and accurate manner. The plate always remains pinched between the two central rolls, preventing slips.
The linear guide configuration of the 4HEL series allows pre-bending to not require tilting the plate below the feeding level, so horizontal feeding tables may be used for easier feeding. The 4HEL also allows the plate to be rolled to the desired diameter immediately after the first pre-bending. The processing method of the 4HEL machines allow the cylindrical ferrule to be made in one pass.
The 4HEL Series comes standard with linear guides for roll motion, four independent bearings supporting the lower rolls, bearing seats with double width, and electronic synchronisation of roll parallelism. It uses Siemens numerical control and has centralized manual lubrication. Faccin offers side motorized rolls, an automatic loading and unloading system, a motorized feed table, an integrated welding system, and more as optional features.
