ROUNDO 3-Roll Plate Bending Machines Type PS
ROUNDO3-Roll Plate Bending MachinesType PS
Universal Machine used for all Plate BendingDouble Pinch Design1. Align the plate using the alignment groovesin the lower rolls or against the rear roll. Theprebending is accomplished by clamping the platebetween the top roll and one of the lower rolls.The other lower roll is in a lower position.PS 360ROUNDO is the world’s leading manufacturer of plate and sectionbending machines. The company was formed in 1964, and hassince delivered more than 16 000 machines to satisfied customers around the globe. ROUNDO machines are world-renownedfor outstanding performance, reliability and quality.Wide Range of MachinesThe standard range of 3-roll plate bending machines covers platethicknesses from 3 mm (1/8”) to 100 mm (4”) and widths from1 000 mm to 8 000 mm (3’ to 26’). All machines have uniquefeatures needed for high precision and versatility: PS 310 PSS 700Prebending of both the leading and trailing edge. In manycases, the remaining flat end is as short as one time theplate thickness.Fully hydraulic, infinitely variable speed drive and adjustment of the rolls.Highest drive torque of any comparable machine.Frames made of high-strength steel, welded and fullystress relieved before machining to have sufficientstrength to absorb bending forces and to achieve highestpossible accuracy.All purpose machine with wide working range.Excellent for cone bending.
2. The plate is bent towards the toproll by the other roll; and the plateedge is prebent to minimum flat endpossible. A length of the plate is rolledand radius is checked.3. Roll the plate through the machineand bend to desired diameter.Most Versatile Plate RollThe ROUNDO PS machines are the most versatile yet costeffective bending rolls available today. The pinch/pyramiddesign provides excellent prebending capabilities of both endsof the plate without the need to remove, turn, and re-insert theplate. Yet, by positioning the rolls in the pyramid (symmetric)configuration, maximum bending capacity can be obtained, aswell as maximum cone bending capabilities. The ROUNDO PSmachines provide a large opening between the upper and lowerrolls, permitting heavy bars and even such unusual items asstair stringers for spiral staircases to be rolled. Versatility canbe further expanded by the addition of attachments to roll flatbar on edge; and, on many models, angle iron, T-bar, channel,pipe and other sections.Heaviest Frame ComponentsThe main frame on all ROUNDO PS machines is welded steelconstruction, machined and line bored using the heaviestcomponents of any competitive machine for addedstrength and rigidity. ROUNDO is the only manufacturer who stress-relieves every frame after welding.Largest Rolls & Roll Shaft BearingsThe rolls are made from high carbon-contentsteel forgings for maximum surface hardnessand are the largest diameter rolls of any comparable machine. To achieve optimum bendingresults, the rolls are crowned in a special manner to compensate for the deflection under load.The amount of crowning is calculated by computer to achieve the largest possible thicknessrange. The rolls are journalled in oversized SKFroller bearings for greatest efficiency and long life.4. Lower the clamping roll and raisethe other roll until the plate is clampedagain. Roll the plate into a closed cylinder and prebend the second plate edge.PS 3105. Finished cylinder is released fromthe machine by lowering the drop end.
PS 500PS 500Interchangeable top rollHighest Drive TorqueROUNDO PS machines provide the greatest drive torque of anycomparable machine. Greater drive torque means the plate cangenerally be rolled in fewer passes to a tighter diameter. All three rollsare driven at all times. Smaller models incorporate a central hydraulicmotor, and larger machines have separate hydraulic motors for eachroll. Electronically controlled infinitely variable rolling speeds givethe operator full control of the bending process, and are standardon every ROUNDO PS machine.Single hydraulicmotorSeparate hydraulic motorsDrop endGreatest Bending Roll ForceThe two lower rolls are individually adjusted by hydraulic cylindersat both ends of the rolls. These are sized to allow ROUNDO PSmachines to generate more bending power than any comparablemachine. Parallelism of the rolls is one of the most crucial factors inachieving good bending results. This is assured on all ROUNDO PSmachines, even under maximum load, by the use of series connectedcylinders on smaller machines and digital controls on larger machines.In addition, the lower rolls, and optionally even the top roll, can betilted to facilitate the widest cone rolling capacity.Massive Drop EndThe drop end, or end yoke, is very heavily proportioned and hingedat two swiveling points placed so that they counteract the forces fromthe lower rolls against the top roll. This construction eliminates anytendency for the drop end to twist.User-Friendly ControlsPortable controls are utilized as operating controls on the variousmodels. They are designed and arranged to enable the operator tostand at the position best suited for viewing and safety duringrolling. Electronic digital readouts or dial indicators areprovided to facilitate repetitive rolling operations.Tilting the rolls for cone rolling is accomplishedby push button controls.Excellent for Cone BendingThe cone bending attachment is mountedon the upper roll at the drop end and isused to slow the small end of the pre-cutcone plate, giving it a lower speed than thelarge end as they move through the machine. With this attachment and standardpower tilting of the lower rolls, cone bending is greatly facilitated. To further enhancecone bending, the machine can be optionallyequipped with a tiltable top roll.Portable controlCone bending
Side support andoverhead supportCombined horizontal/vertical design Optional EquipmentROUNDO PS machines are the best equipped and most versatile inthe industry, yet there are applications where the addition of optionssuch as material handling equipment, bar bending attachments, special top rolls, or special controls such as ROUNDO’s exclusive PSR/wCNC² are called for. For those applications, we offer the following:Interchangeable Top RollWhen rolling parts to diameters smaller than the standard top rollwill permit, an interchangeable top roll may be installed. This smallerdiameter top roll can be easily exchanged with the standard top roll,further enhancing the machine’s versatility.Interchangeable top rolls with special crowning or special machiningto accommodate unusual applications can also be installed.Overhead and Side SupportsAll PS machines can be equipped with hydraulically operated sidesupports on one or both sides to support the material as it enters orleaves the machine. An adjustable top support to support the materialfrom overhead helps reduce deformation of the rolled plate. Thesesupports can be ordered mounted on the machine when shippedfrom the ROUNDO factory, or added later as requirements warrant.This flexibility allows the machine to be equipped in a manner thatenhances efficiency, safety and productivity.Support rolls underthe lower roll for longmachinesHardened, Ground and Polished RollsFor stainless steels and other materials with high strength limits, orwhen frequent cone bending is anticipated, hardened and ground rollsare recommended. To avoid cracking and warping issues, the rollsare hardened using the preferred 7-step surface hardening process,followed by precision grinding and polishing.PS 460PSS 960

This system can control up to 7 axesand the possibility to use USB memory allows an infinite number ofbending programs. Optionally, three of these axes can be positionedsimultaneously, providing an interpolation function. Programmingmay be done via integrated keyboard or with fast teach-in function.Other Control optionsThe ROUNDO RLC/1 Position Control System is a basic positioningcontrol with 2 pre-set values for each axis (one for up and one fordown). The positioning control automatically stops the movement ofthe bending roll when the preset value is reached. This system isdesigned to make repetitive bends, eliminating the needto manually stop at all required positions.Portable controlconsole with doubledigital readoutsROUNDO3-Roll Plate Bending MachinesType PSE and PSSROUNDO also produces a range of smaller3-Roll machines, type PSE.Type PSS is our range of massive capacity3-Roll machines with separate hydraulic motorsand roll diameters up to 1000 mm (40”).Please contact us for detailed information.Electronic Digital ReadoutsThe digital readout is in place of the standard dial indicators.
