Gasparini presents the X-Press: the state-of-the-art in sheet metal press brake forming

Sheet metal is deceptive: what does "A36 steel" stands for?

Sheet metal is labelled according to its minimum yield strength. A36 steel corresponds to 36,000 psi, but will include much stronger steels. Moreover rolling, holes and cuts create internal stresses. Sheet metal is unpredictable, so what?

During forming, upper ram bows in the center. There, the punch will be farther from the die, so the angle will be sharper at the ends and wider in the middle. A difference as small as 0.0019" in depth leads to a 1° difference on a 0.3" V-die.

This effect is corrected by crowning: the table is raised to keep the die at a constant distance. But how much do we have to raise? Most manufacturers rely upon theoretical plate strength charts. Actually, it's pointless because the material is unpredictable.

To solve this issue, Gasparini has patented the ACSG active crowning. A sensor in the ram detects bowing. Cylinders in the table raise the die, while another sensor measures the height. When the two values are equal, punch and die are at the same distance and the profile will have a constant angle across its length.

ACSG is just one of many accessories that make X-Press the most advanced press brake in the world. X-Press is a tailor-made machine, entirely designed and built by Gasparini, including the frame and the hydraulic circuit. A 40-year experience led us to develop many more custom solutions that no one else can offer. Just to mention a few:

• ECO inverter: record-breaking speed and energy efficiency

• Laser DSP-AP: safely reduces cycle time

• GPS4: embedded angle measurement that works better than lasers, even on complex shapes, on any surface finish, and no setup is required.

• Backgauges: either on beam or on towers, for conical bends up to 80°, with sheet followers and retractable supports.

• Patented upper and lower clamping for all tooling styles, with manual, pneumatic or hydraulic operation.

• Delem or Phoeni-x CNC with remote assistance, 3D file and bending sequence import. Robot and company server interface.

The most important companies in the world chose us because we are the technological leaders in sheet metal forming. Contact us for a quote on www.gasparini.it/en
