Electro Hydraulic Synchronous CNC Bending Machine vs Hybrid CNC Bending Machine

Today, let's talk about which is better for the electro-hydraulic synchronization CNC bending Machine and hybrid cnc bending machine

 

At present, customers who buy CNC bending machines are overwhelmed with a wide range of models and do not know how to choose. Let's talk about which one is more suitable.

 

The main cylinders on both sides of the electro-hydraulic synchronous CNC bending machine synchronously adopt a hydraulic control system such as a proportional electro-hydraulic servo valve and a grating ruler to form a closed-loop control, which is independently restricted by the CNC and feedback accurate data to ensure the accuracy of the slider operation.

 

Electro-hydraulic servo bending machine: The computer controls the flow and pressure of the Y1 and Y2 cylinders through two sets of servo bidirectional pump systems. The oil in the upper cavity of the cylinder is directly pumped into the lower cavity of the cylinder through the oil pump to realize the upper mold lifting and the oil pump reverse. The oil in the lower cavity of the cylinder is directly injected into the upper cavity of the cylinder to realize the bending of the sheet material. The left and right synchronization of the upper die of the machine tool is controlled separately by two sets of servo bidirectional pumps. The machine tool not only has high precision, energy saving, low noise, but also is more stable and reliable, and uses less oil, which is conducive to the manufacture of large-stroke and ultra-high-speed bending machines.

 

The previous bending machines were all torsion axis synchronous bending machines or valve-controlled bending machines. The hybrid servo CNC bending machine was a real pump-controlled bending machine, and the synchronization of the machine tools relied on pump control.

 

The electro-hydraulic synchronous CNC bending machine and the hybrid hydraulic bending machine are like a tractor and a car, in different types. In comparison between the two, the former is first of all cheap and suitable for bending large sheet materials, and the CNC bending machine is more cost-effective at 250T or more; the latter, except for the high price, has other advantages, through two sets of servo bidirectional pumps The system controls the flow and pressure of the Y1 and Y2 cylinders respectively, and directly pumps the oil in the upper cavity of the cylinder into the lower cavity of the cylinder through the oil pump to achieve the upper mold lifting. The reversal of the oil pump drives the oil in the lower cavity of the cylinder directly into the lower cavity of the cylinder to realize the press bending of the upper die. Suitable for 160T-250T, fast down 200mm/s, return 200-350mm/s, the left and right synchronization of the upper die of the machine tool is controlled separately by two sets of servo bidirectional pumps. The machine tool not only has high precision, low friction, high synchronization, energy saving, low noise, but also saves electricity, fuel, is more stable and reliable, and occupies a small space, which is conducive to manufacturing large-stroke and ultra-high-speed bending machines.
