Product DescriptionL:
the tandem hydraulic press brake is use to bend the long sheet metal in some industries. The tandem press bake also can bend the light pole , lamp pole and electrical pole. It can bend round pole and polygon pole.
Synchronization working principal of tandem machines: Adopting electric-hydraulic proportional 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.
