WC67Y Tandem hydraulic press brakeSpecificationsTandem Press Brake 1.High performance, 2.CQC,ISO,CE certificatiTandem Press BrakeDescription: 1. Electro-hydraulic servo system,closed loop controls slider running accuracy.2. The unique patented technology:bilateral deflection compensation of the large press brake .3. Open width adjustable inserts die to meet a variety of workpieces.4. A variety of auxiliary institutions could meet users’ requirements and make the process more convenient and efficient.5. The frame of machine is composed of tank, worktable, left and right housings and ram. So it has high strength and good rigidity. Also it takes vibration to eliminate stress.6. Synchronization working principal of both machines:Adopting electric-hydraulicproportional valve to ensure the synchronization of both machines. The proportional valve is made by BOSCH company with very good performance such as small friction between mechanic action pairs, fine electronic amplifier and electric magnet with high controlling force and continuous action. There are two raster displayers on both sides of machine to inspect the position of ram continuously and feed back the signal to control system, then the control system will control electric-hydraulic valve to make two cylinders synchronization on one machine. Because the raster displayers are installed to "C" plates, not on housing plates directly, the deflection of ram and frame when working will not effect its measuring and controlling precision. When two machines working together, the differential potentiometer installed between two machines will transfer the mechanic synchronizing signal into electronic one and feed back to synchronization plate and control system. The signal will be enlarged by BOSCH amplifier to control the
