“Can we achieve a constant bend on different lengths?”
“Yes, by compensating for the deflection of the machine’s structure.”
During the bending process, the side frames are subject to deflection as a result of a throat design.
This effect results in the top beam moving away from the lower beam, compromising the accuracy of the control systems.
Only a machine equipped with a compensation system such as the REFLEX system can overcome and correct this unavoidable problem.
REFLEX, the proportional compensation system
It corrects the side frames deformation so as to get a perfect bend across the entire length of the part
Reflex is a system designed by Gasparini to monitor the press brake structure’s deflections. The system, which is installed on all Gasparini press brakes, is composed of a sliding device, connected to the linear encoder, which is placed on the “C” side frames anchored to the lower beam. These side frames are not affected by the structural deflections as they are not connected to the machine’s frames, and allow a correct positioning of the top beam, thus achieving the same bending angle along the whole work piece.
Independent from the length, the thickness and from the position of the work piece, as well as from the side frame deflections that may arise due to the loading force, the position of the top beam is constantly checked during the bending process so to assure a constant angle.
