Press brake has adaptive bending system

Servo-controlled hydraulic downstroking press brake equipped with a laser-based adaptive bending system has powerful software that ensures full-length accuracy on long parts.

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.

* Powerful CADMAN CNC 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.

* Advanced angle measurement with Easy-Form Laser - the PPEB press brake displayed at Euroblech featured LVDs Easy-Form Laser adaptive bending technology.

Easy-Form Laser is a unique angle measurement device that uses a laser to monitor 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 hydraulics - the press brake displayed at Euroblech was equipped with a high-speed turbo hydraulic system, which is now available on PPEB press brakes up to 3500kN (350 tonf).

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.

PPEB press brakes are available in working lengths from 1.5 to 15m with tonnages up to 3MN (3000tonf).

LVD is a leading manufacturer of metalforming equipment, including turret punch presses, flexible fabricating systems, laser cutting machines, press brakes, guillotine shears, press brake tooling, and CAD/CAM programming software.
