◇ Streamlined design, high speed, high precision, high rigidity, CNC sheet metal press brake.
◇ Electro hydraulic servo system, full loop controlling the synchronization of the upper beam.
◇ Hydraulic compensation on crowning of work-table and deformation compensation on throat, ensuring good bending strength and precision.
◇ Back gauge driven by digital AC servo motor, moved with long-stroke ball screw, linear guideway guiding.
◇ Supplying one set of European type upper tool and mechanical wedge clamping
◇ Supplying one set of 2-V fast change lower tool
◇ The front sheet-support position can be adjusted step by step along the worktable
Control
The synchronization of press brake adopt the technology of full loop electro hydraulic servo control, the positioning signal of the upper beam are feed back by raster (light-ruler) to CNC system and CNC system will check the opening size of synchronizing valves, adjusting the inlet oil amount, to realize the synchronizing movements of the upper beam (Y1, Y2) and keep the worktable are always in parallel situation. Following the situation of sheet metal to be bended, CNC system control automatically the amount of the crowning compensation of worktable to realize that angle being bended of workpiece can keep same a long the full workpiece length.
Crowning Compensation
Crowning compensation system on worktable can make a workpiece having a same precision full along the length of the worktable. A crowning compensation system is composed of group cylinders in line in worktable, which can form a relative movements of worktable, forming a curve needed of adding convex to worktable, to ensure unchanged the relative position to the upper beam of worktable after the worktable being under pressure. The crowning compensation amount is automatically calculated out by CNC system according to the workpiece's situation.
CNC System (Delem-- DA56)
◇ Patent WinCE platform for press brake application, instant shut-off keep system reliably running
◇ 10.4" TFT color LCD, real scale display machine, tooling and products, easy to use
◇ 2D programming, automatic bend sequence calculation, Automatic collision detection
◇ Calculating of the crowning compensation to the worktable
◇ Integrated A graphical analysis tool
◇ Self-learning correction database
◇ Network and Remote diagnostics
◇ System diagnosis
