1, adopts full steel welding structure, with sufficient strength and rigidity; 2, hydraulic transmission, machine placed on both ends of the cylinder on the slide block, direct drive sliding work; 3, the slider with torsion shaft synchronous mechanism forced synchronization; 4, by using mechanical structure, stable and reliable; 5, stroke motor speed adjustable, manual fine tuning, counter displays. 6, inclined wedge deflection compensation mechanism, to ensure the high precision of bending. Hydraulic cutting machine including stent, workbench and clamping plate, workbench on the scaffold, workbench consists of base and the clamp, the base through the hinge is connected with the clamping plate, the base is composed of shell, the coil and plate, coil placed inside the shell of the sag, the depression at the top of the cover plate. When used by a conductor to coil electricity, after electrify produces gravity to clamp, so as to realize the clamping plate between the pressure plate and the base. With the electromagnetic clamping, making plate can be made into a variety of workpiece requirements, but also to have a wall of workpiece processing. Plane can slot machine by changing the slot machine mold, so as to meet the needs of various artifacts.
