Hydraulic press brake PP 80/4000

• The whole body is designed and built as a welded one piece frame and machined at one time on a moving column CNC machining centre • Hydraulic cylinders are machined from a solid steel billet and honed precisely • Pistons steel forgings, hardened, chrome plated, precision ground and micropolished • Compact hydraulic block with pressure relief valves for safety • The torsion bar and stooper system inside cylinders enable parallel move of the top beam and accurate bend angle at both ends of the work piece • Pre-fill valves enable top beam to approch the work piece rapidly, and return rapidly after bending • Pressure switch limits bending force during bending and activate automatic return of top beam to top dead centre • High pressure and silent Rexroth hydraulic pumps Standard Accessories • Motorized cylinder stopper control system • Motorized rigid backgauge (X axis) system with ball screw and special design guiding system with minimized lubrication • Two laterally adjustable front support arms with slot for height adjustment and slot front stop. • Longitudinal (Z axis) and vertical (R axis) adjustable of backgauge system • Backgauge positioning fingers move along linear slideways and has depth adjustament facility of +/- 0,05 mm. tolerance for exact parallelism • Backgauge fingers with two gauging steps used one for short and the other for long bending depths. Fingers have fold up feature • Dysplay and push buttons for backgauge and cylinder stopper positioning • T slots on both sides of the table • PLC electrical system • Swinging control panel • One piece top and bottom tool (not hardened)
