The press brake is a machine that can bend thin plates. Its structure mainly includes a bracket, a working table and a clamping plate. The working table is placed on the bracket and is composed of a base and a pressing plate. The base is connected with a hinge and a clamping cover. When in use, the wire is energized to the coil, and the gravitational force is generated on the pressing plate after being energized, so as to realize the clamping of the thin plate between the pressing plate and the base. Due to the electromagnetic clamping, the pressing plate can be made into a variety of workpiece requirements, and the workpiece with side walls can be processed, and the operation is very simple.
Bending machines are divided into manual bending machines, hydraulic bending machines and CNC bending machines. Manual bending machine is divided into manipulator, dynamic bending machine and electric manual bending machine. Hydraulic bending machine can be divided into torsion axis synchronization, machine-hydraulic synchronization and electro-hydraulic synchronization according to the synchronization method. Hydraulic bending machines can be divided into up-moving type and down-moving type according to the movement mode.
