Servo-controlled high speed press brake
LVD will display a PPEB servo-controlled press brake featuring the Easy-Form Laser adaptive bending system and high-speed turbo package at MACH2006, Hall 4, stand 4665. The PPEB-EFL Turbo 80/25 - 80 Tonne by 2.5 metre model will be exhibited. In process Advanced Angle Measurement with Easy-Form Laser The PPEB press brake displayed at MACH2006 will feature LVD’s Easy-Form Laser adaptive bending technology.
Easy-Form Laser is a unique angle measurement device that uses a laser to monitor and correct the angle in real time during the bending process, producing accurate bending results from the first piece.
Easy-Form Laser uses symmetrical measurement at the front and back of the die to determine the exact value of the angle of the workpiece.
The system projects straight lines composed of multiple light points onto the workpiece and the vertical part of the die, providing a measurement calculation every 20 milliseconds.
The sensing device transmits information in real time to the CNC control unit, which processes it and subsequently recalculates the correct depth adjustment to obtain the correct angle.
The bending process is not interrupted, and no production time is lost.
Unlike mechanical angle control systems, Easy-Form Laser does not extend the cycle duration and provides accurate results consistently.
It does not require calibration after each set-up.
High-speed Turbo The press brake displayed at MACH2006 will be equipped with a high-speed turbo hydraulic system, which is now available on PPEB press brakes up to 350 tons.
The turbo system increases the approach, pressing and return speeds of the press brake ram by as much as 30 percent compared to standard machines of the same size and type.
Increasing the operating speed of larger capacity press brakes improves flexibility and provides the ability to produce parts that would typically be assigned to smaller machines with higher performance.
Faster pressing speeds improve the output of higher tonnage press brakes particularly when using wide dies that require deeper penetration of the punch and longer ram travel.
LVD’s PPEB series of precision press brakes are equipped with state-of-the-art hydraulics and electronics and are offered in multi-axis configurations.
PPEB press brakes are built on a rigid frame design to ensure accuracy.
PPEB press brakes are available in working lengths from 1.5 to 15 m with tonnages up to 3000 tons.
Powerful CADMAN CNC Control and Software All PPEB press brakes feature the exclusive CADMAN control.
CADMAN is a powerful PC-based control complete with Windows operating system and the CADMAN-B 3D programming software.
The high quality design of the press brake coupled with the CADMAN control help ensure the consistency of the bend over the entire part length.
The CADMAN control, equipped with an Intel Pentium microprocessor and a 2-gigabyte hard drive, creates and stores interactive databases for bend allowance, angle corrections and spring-back.
These user-generated databases, created by actual bending results, are searched and applied each time a part program is generated.
This automatic optimization of the part program eliminates trial bending, and reduces the time required to produce a quality part.
CADMAN-B 3D software is standard in the machine control and is available as an offline programming system.
The databases developed and maintained in the PPEB press brake can be duplicated and downloaded to the offline system.
Having actual bending technologies available prior to part creation eliminates unwanted errors in the actual blank generation prior to bending, and assures accurate part tolerances throughout the process.
The LVD group based in Gullegem - Belgium is a leading worldwide designer, manufacturer and distributor of a comprehensive range of sheet metal / plate working machine tools and software solutions, including laser cutting systems, punch presses, press brakes, guillotines and automated flexible manufacturing systems - all supported by its’ CADMAN PC-based, Windows compatible programming system for punching, laser cutting and bending.
