For Plut, a manufacturer of metallising equipment, we produced an 80 t hydraulic press brake with a table length of 2100 mm. The press brake was configured with our Next design, the top of the range in press brakes. The bench-cross span is 500 mm, with a Y-axis travel of 300 mm and the work area has LED lighting. This machine has been set up with the Tele-Link remote assistance function, the CNC is Delem DA-69T type and the offline software is Delem Profile-T 3D.
The backgauge is 5-axis (X-R-Z1-Z2-X6) CNC-controlled, which in addition to the two standard axes also features the Z1 and Z2 axes. It is characterised by the addition of a stop on a backgauge reference for an increased depth of support during the bending process.
The safety system installed is the Laser DSP-AP type with lowered speed change point and reduced cycle time.
To give the machine greater precision, the customer chose to equip it with the Laser Line system for reference-free bending. In fact, Laserline projects a laser beam onto the sheet metal sheet at the bending line and allows verification that it is in the correct position for processing. It can also be applied at a later stage in already installed press brakes, depending on the version of the CNC used.
With regard to the choice of intermediates, the customer decided to use the Toolever self-aligning quick-release lever clamp with a height of 100 mm. Thanks to the tool-free lever operation, this system allows a clear time saving compared to traditional screw clamps.
The 100 mm height, which is the same as that of manual screw intermediates, does not require reprogramming of the CNC and the centring wedge is front-adjustable. This allows the intermediates to be aligned adjacent to each other.
The lower clamping is of the pneumatic type.
This press brake is equipped with the E-Reflex Deformation Compensation System, which monitors the bending of the structure thanks to a network of sensors located inside the machine and in the hydraulic system. The error is measured and compared with the crosshead position and oil pressure. This makes it possible to calculate the actual height at which the punch is located, irrespective of deformations.
Furthermore, this press brake was designed with the ECO energy-saving system, thanks to which energy waste can be significantly reduced, thus improving productivity. The customer chose to equip it with 2 front supports and a standard foot pedal.
