Hydraulic bending machines are classified into upper tool moving and lower tool moving types according to their moving manner. A press brake machine is generally comprised of a bracket, a working table and a clamping plate; wherein the working table consisted of a base and a press plate is arranged on the bracket. The base composed of a base housing, coil and a cover is connected with the clamping plate through hinges, among which the coil is arranged in the recess of base housing. During operation, the coil is energized to generate attractive force upon the press plate so as to clamp the sheet between the press plate and the base. Since the electromagnetic force is used for clamping, the press plate can process various kinds of workpieces including those possessing side walls. By changing the dies for bending, the sheet metal bending machine can process various kinds of workpieces.

Our hydraulic swing beam shear is one of the most preferred options for sheet metal forming, thanks to its advanced technology and dependable performance. Its application has expanded across various sectors, including aerospace, shipbuilding, railways, electrical engineering, mining, construction machinery, metallurgy, automotive, and agricultural machinery, driven by continual improvements in process technology.
