DEA S-LINE

Small range plate bending machine

ADVANTAGES of SERTOM P.B. DEA 3RS

AUTOMATIC SYNCHRONOUS BALANCING: massive TORSION BARS working in symbiosis with sofisticated valves controlling the oil flow . This system grants the complete and steady parallelism, in every working enviroment and conditions.

PLANETARY SWING GUIDES:  planetary movement that reduces frictions

HIGH EFFICIENCY and ENERGY SAVING: planetary / epicyclic gearboxes DIRECTLY COUPLED the rolls and the hydraulic motors. All the machine strength is focused on the material to bend (positive strength) with consequent Energy saving and machine efficiency.

DIRECT DRIVE MOTORIZATION: two hydraulic motors, directly assembled to the rolls by a direct drive transmission. Planetary gearboxes that give the maximum performances with the minimum possible strength. The motion is given to the motors through an hydraulic pump, which is set in action by an electric motor, and it is transmitted (via planetary drives) to the rolls.

ROLLS CAMBERING / CROWNING

Application on rolls of a variable cambering on the basis of material thickness. Each machine is different, because its rolls do not have the same cambering / crowning. During the bending work, the rolls get subject to deflection but (thanks to the cambering) they do not reach the breaking point, and grant perfect results in their bending performance.

THE SHORTEST UNBENT FLAT

With our plate rolling machine, the short flat part will be only 1.8 times the plate thickness.

TOP ROLL CONTRAST TO EJECT PIPES

When the machine is endowed of conical bending device, a system called contrast is used to eject the pipe. Our system is composed of a piston, on the back side of the roll, that monitors the yoke position, when it’s down, the piston moves and lifts the top roll to let the operator eject the pipe without problems. The monitoring is made by a sequence valve that “feels” the pressure increasing in the hydraulic circuit when the yoke opens, transferring it to the contrast piston that lifts the roll.

PERMANENT LUBRICATION SYSTEM

Using high quality and high resistance materials, SERTOM P.B. can grant a system of permanent lubrication. With our autolubricated bearings it will be enough only to grease the parts during the assembling.
