Working Principle:
Oil-electric hybrid CNC bending machine adopts the working mode of combining CNC technology and electro-hydraulic servo technology, through controlling the output of electro-hydraulic servo system, so as to control the machining process of the machine tool. Hybrid CNC bending machine is a multi-functional bending machine emerging in recent years at home and abroad, which adopts a new drive mode, that is, motor-driven oil pump, the output of high-pressure oil, respectively, to drive the cylinder double action, in order to achieve the rapid downward movement of the table and the table’s rapid return.In the oil-electric hybrid CNC bending machine, the power output of the main motor is higher than the power output of the main motor of the ordinary bending machine, which makes it faster in the processing of thick plates. Another speed advantage of the oil-electric hybrid CNC bending machine is that it uses an advanced CNC system.The CNC system can make the oil-electric hybrid CNC bending machine achieve higher processing speed during the machining process by precisely controlling the rotating speed of the electric motor. In addition, its cutting speed and motor speed can be set and adjusted at variable speed on demand, which greatly facilitates the processing operation of the equipment.
Electro-hydraulic bending machines, on the other hand, use a combination of hydraulic systems and mechanical structure of the work, through the transfer of hydraulic energy to control the process. Electro-hydraulic servo bending machine is also a common bending machine. Its working principle is that the electro-hydraulic servo control system controls the amount of hydraulic oil in the cylinder body through the electro-hydraulic servo valve, thus realizing the up and down movement of the worktable.Compared with the oil-electric hybrid bending machine, the electro-hydraulic servo bending machine outputs less high-pressure oil, so its working speed is relatively low. At the same time, the electro-hydraulic servo bending machine can ensure precision and stability during processing through a more precise electro-hydraulic servo control system.

The compensation quantity is automatically adjusted by the CNC system, which is convenient and precise. Electro-hydraulic servo CNC bending machine adopts a full-featured rear blocking mechanism, which can be selected to control multiple rear blocking axes. Functional parts in the rear blocking.Such as guide rails, screws, bearings, etc. are selected from imported originals to ensure the blocking accuracy of the rear blocking.

The advantages of electro-hydraulic servo CNC bending machine are faster processing speed, higher precision, less noise and more efficient energy utilization.The existence of these advantages means that it is able to perform a variety of different metal material processing tasks more intelligently, increasing productivity and reducing costs. Electro-hydraulic servo CNC bending machine is a high-precision, high-efficiency CNC processing equipment, suitable for a variety of different materials and thicknesses of sheet metal processing.

Oil-electric hybrid CNC bending machine energy saving of about 50%, the total volume of the oil tank as long as 110L, than the traditional electro-hydraulic bending machine fuel savings of about 70% or more. Optimization of the core configuration of the cylinder upper and lower chamber area ratio, the size of the oil pump, the main servo motor power, the form and size of the liquid filling valve, the integrated response of the oil circuit, reducing the cycle time, efficiency gains of more than 30%. The motor, pump, valve, tank, filter and cylinder are all integrated without external piping, which improves the oil response efficiency, reduces the risk of oil leakage, and also reduces the installation and service costs.
The oil-electric hybrid CNC bending machine adopts dual servo motors to directly control the oil pump technology, pump control instead of valve control, reducing the throttling loss, small temperature rise, and prolonging the service life of the oil. With the application of control system, the positioning accuracy is up to 5μm, which reaches the international first-class level and meets the needs of the vast majority of high-precision bending process, and provides guarantee for the subsequent welding, riveting, splicing and other processes.The servo motor can stop working when the system does not need the flow or pressure function, reducing noise and improving the working environment. Oil-electric hybrid CNC bending machine can significantly save energy, save fuel, improve bending efficiency, reduce the risk of oil leakage, reduce installation costs, extend the service life of consumables, improve the bending accuracy, reduce noise, improve the working environment, for sheet metal business owners and bending operators are worth paying attention to the processing of the tool.
