Technical Field

[0002] Bending machines are divided into manual bending machines, hydraulic bending machines and CNC bending machines. Manual bending machines are further divided into mechanical manual bending machines and electric manual bending machines. Hydraulic bending machines can be divided into torsion axis synchronization, mechanical-hydraulic synchronization, and electro-hydraulic synchronization according to the synchronization mode. Hydraulic bending machines can be divided into upper-moving type and lower-moving type according to the movement mode. In the existing hydraulic sheet metal bending machines, the oil pump has a coupling plate transition and is connected to the motor through a coupling to form an oil pump motor unit. The machining accuracy of the coupling plate has a great influence on the working noise and wear of the oil pump and motor.
