2 The XXL-Center: A Revolution in Does this sound familiar? Your bread and butter is in long parts, but to bend them requires two, maybe three operators. The floor space in your factory is shrinking fast and the time, effort, and cost required to handle material has become increasingly expensive. RAS introduces: World's first automatic folding center for long parts. Now... Imagine this! Bending your long parts has never been easier and more flexible than with the RAS XXL-Center. One operator simply loads the workpiece onto a sheet support system in front of the machine, and then unloads the complete folded, finished part. That's it. The machine automatically inserts, squares, positions to the bend line, and bends the flanges up or down. No more rotation. No more complicated handling. No more second or third operator. You get precision parts automatically produced in record time! And, because of the unique motion of the machine's tools it is possible to bend pre-coated sheets without scratching the material surface! Hems will be closed to a programmable dimension and this dimension will be the same all along the part. Where in the past it has taken hours to complete a certain job, the same task can now be done in minutes! Programming is so simple that even less experienced operators can produce perfect parts in no time. The XXL-Center automates the entire bend sequence, and eliminates operator involvement. If you want to produce long parts with breathtaking speed, unheard of precision and repeatability, and if you want to eliminate most of the handling costs that eat into your profit, then RAS has a revolutionary solution for you.

3 Forming Long Parts. The MULTIBEND 9002 CNC The CNC is the center of the intelligence of the XXL-Center. It drives all of the actions with unheard of speed and accuracy. Programming with the superior RAS CADalyzer software is so simple that all you need is to enter angles and flange dimensions for each bend. If what you see on the screen is what you want you simply press the START button and the forming process is started. The CADalyzer software offers maximum ease of use: Graphical input of the angles for up or down bends and the flange dimension. On-screen simulation of the entire bending sequence or a single bend for visual collision checks. That's all! So simple. So easy to use. So quick. Just press START and there you go! The CADalyzer also allows: Programmable open or closed hemming dimensions. Thickness based springback compensation by using technology tables. Material based springback compensation for the entire program or a single line. Composition of an order sequence in a job list. Number of parts being produced of the selected profile. Automatic calculation of the stretch out of the developed material width or the remaining flange dimension. Integration of manual bending operations e. g. to close a hem in the middle of the part. Program storage on diskette or in the RAM. Offline programming an DNC communication. CAD data import from ASCII or Excel files. Some technical Highlights of the MULTIBEND 9002: 4 axes under CNC control (upper clamping beam, upper and lower folding beam, feeding gripper system) TFT color graphic display with a 264 mm/10.4" screen 32-Bit-RISC-Processor for high speed motions Optional DNC communication Optional off-line software Optional integrated modem for Teleservice Service- and diagnostics software with an integrated oscilloscope Disk drive for unlimited program storage 3 MB empty RAM Flash-E-Prom for future software updates without changing hardware Three RS 232 interfaces for data communication State-of-the-art CAN-Bus technology Color panel for highest ergonomic requirements The CADalyzer- Software shows a picture of each step and simulates the bending sequence.

4 The XXL-Center: Long on L The two folding beams bend the part up and down. Upper and the Lower Folding Beam A masterpiece of engineering brilliance, the folding beams were designed to rotate during bending by only a few millimeters, and to roll away with the workpiece in a 3D motion. This motion insures that material surfaces will not be scratched. Depending on whether a part needs to be bent up or down, the active folding beam moves forward to the material, while the counter folding beam retracts to its home position. The free space created by this functionality provides part design capabilities never before seen on a metal folder. Powerful motors ensure the strength and speed required for high production volumes. The 3D-folding beam motion assures scratch-free bending of even sensitive materials. The CAD designed and Finite-Element optimized folding beams offer a strength of more than 1000 N/mm2 (145,000 psi), and are dimensioned to resist highest loads. The folding beams are supported every 270 mm/10.63", two to three times more than on other designs. This design assures perfectly straight bends everytime. You can always expect more from RAS! A free space of up to 300 degrees allows the production of the most complicated profiles.

5 ength complete in Detail! The Drive System Concept This XXL-Center uses no hydraulics. Instead, regulated and brushless AC-motors bring power and speed to the entire system. Forget about oil leaks, uneven clamping, hems that are not consistent along their length or even over stressed machine components. All motors are placed at the center of the machine. This assures optimum flow of forces to the very end of the machine bed. The drive concept is responsible for the exact parallel motion of all beams, guaranteeing extremely straight bends and programmable hemming dimensions, where the hems are closed to the same height along the complete length of the part. Programmable hemming dimension. Upper and the Lower Clamping Beam Tools with an extremely high tensile strength and with a 1.5 mm/0.06" radius are built into the upper and lower clamping beam. If they show wear after intensive use, they can easily be replaced. The XXL-Center bends all materials and all material thicknesses with this inside radius plus the material springback. The right and left end of the machine extends past the power unit by only 215mm/ 8.465". This minimum length demonstrates RAS' efforts to offer a superior rigid system. Changeable tool built with an extremely high tensile strengh and a 1.5 mm (0.06 ) radius. The Power Units On conventional long folders the upper and lower beams are just bolted with a single connection of to each frame. The RAS XXL-Center does this connection with a special companion joint in two locations for the upper and in two for the lower beam on each extremely wide and heavy power unit. These Connects assure the best flow of force, this reflects in perfect bends. And as the special joints add extra stiffness up to the very front nose of the tools you won't believe how this effects the quality and precision of parts produced!

6 Loading Support Tables The high quality, stainless steel loading support tables are an integral part of the XXL-Center's sophisticated ergonomics. To save time, the support tables come out of the machine to the dimension required for the actual part width. The operator then easily loads material onto these supports. Squaring is not necessary as the machine will do this automatically. As soon as the operator presses a foot pedal, the loading supports move the material into the machine and locate it against the squaring fingers. Stainless steel loading supports for easy material loading. Squaring Fingers The squaring fingers automatically pop-up from the work surface 200 mm/7.87" behind the bend line. Their funnel shape and 80 mm/3.15" height insure that even wavy blanks are easily squared. As the workpiece is squared, the feeding grippers are activated. Funnel shape squaring fingers push the material into the right position.

7 Feeding Grippers The feeding grippers hold the part during the entire bend cycle and position it automatically for each bend. For most parts the operator unloads only the finished workpiece. Only on parts with hems on both sides does the operator flip the workpiece once during the bend cycle. Even then, rotating the part is not required. The feeding grippers can clamp on straight material, but can also clamp above a pre-bent hem or a closed hem. Each gripper unit sits on a separate guiding system with high precision linear guides. This guarantees precision and accurate flange dimensions and a high speed, dynamic drive characteristic. Grippers clamp and position the parts during the bend cycle. The feeding grippers clamp the part in different situations. Parts with hems on both sides require a flip once within the bend cycle.
