The bending machine is a kind of machine which can bend the thin plate, its structure mainly includes support, worktable and clamping plate, the worktable is placed on the support, the worktable is composed of a base and a pressure plate, the base is connected to the clamping plate through a hinge, the base is composed of a housing, a coil and a cover plate, the coil is placed in the depression is covered with a cover plate. When used, the coil is energized by the wire, and after the power is applied, the platen is attracted to the platen, thereby achieving the clamping of the plate between the platen and the base. Because of the use of electromagnetic force clamping, the pressure plate can be made into a variety of workpiece processing, the operation is very simple.
Bending machine is divide into manual bending machine, hydraulic bending machine and numerical control bending machine. Manual bending machine is divided into mechanical manual bending and electric manual bending machine. Hydraulic bending machine can be divided into twisting shaft synchronization, machine liquid synchronization, and electro-hydraulic synchronization according to synchronous mode. Hydraulic bending machine can be divided into: upper and lower according to the mode of motion.
