LA DIFFERENZA TRA PRESSA PIEGATRICE CNC IBRIDA E PRESSA PIEGATRICE ELETTROIDRAULICA CNC

Pressa piegatrice CNC

Principio della pressa piegatrice CNC elettroidraulica

The hydraulic control system such as proportional electro-hydraulic servo valve and grating ruler .

both use to form a closed-loop control for the main oil cylinders on both sides. The CNC use to independently limit and feed back accurate data to ensure the accuracy of slider operation.

Principle of Hybrid CNC press brake

The computer controls the flow, quantity and pressure of Y1 and Y2 oil cylinders respectively through two sets of servo two-way pump systems.

The oil in the upper chamber of the oil cylinder directly pumps into the lower cavity of the oil cylinder through the oil pump to realize the upper mold lifting.

The oil pump reverses and the oil in the lower chamber of the oil cylinder directly injects into the upper cavity of the oil cylinder to realize the bending of the sheet metal.

Two sets of servo bidirectional pumps which used to synchronize the left and right mold of the machine tool Control.

The machine tool is not only high precision, energy saving, low noise, but also more stable and reliable, less oil consumption,

which is conducive to the manufacture of large stroke ultra-high speed bending machine.

Difference

The electro-hydraulic synchronous Piegatrice CNC and the oil electric hybrid bending machine are just like a tractor, a car.

The former, first of all, is cheap, suitable for bending large sheet metal. CNC bending machine is more cost-effective when nominal force is over 250 Tons.

The latter, in addition to the high price, has other advantages.

Through two sets of servo two-way pump system, the flow and pressure of Y1 and Y2 oil cylinders respectively control,

and the oil in the upper chamber of the oil cylinder directly pumps into the lower cavity of the oil cylinder

through the oil pump to realize the upper mold lifting.

When the oil pump reverses, the oil in the lower chamber of the oil cylinder is directly injected into the lower cavity of the oil cylinder

Which realize the downward bending of the upper die.

It is suitable for 160t-250t, quick down 200 mm / s, return distance 200-350 mm / s.

two sets of servo two-way pumps are used to control the synchronization of the upper mold of the machine tool.

The machine not only has high precision, small friction force, high synchronization, energy saving, low noise,

but also saves electricity, oil, more stable and reliable, occupies less space, and is conducive to manufacturing large stroke and super high speed macchina piegatrice.
