Hydraulic press brake Operation Of Hydraulic System

How Hydraulic Press Brake Is Made Operational . And Steps to make Hydraulic Press Brake in

Operation


In This Blog We will Discuss about Hydraulic System in Hydraulic Press Brake.

Hydraulic System

The system in Hydraulic press brake can quickly slide down, slow down, speed work into the bend, and

rapid return upward, downward slide of press brake during emergency stop and other activities.

Power to start the motor, the hydraulic oil by the electromagnetic relief valve 

back to tank, air pump running in the state of hydraulic press brake.

Press the button in press brake  to slide down SB4(or depress the pedal down slider) 

when YV1,YV2 was electric, oil pressure solenoid valve through the orifice

into the hydraulic  cylinder and the upper chamber of press brake machine,

this time before the pressurerise due to orifice high, the check valve open, 

the slider weight and pressure in the oil under the action of the slider rapid 

decline in oil fuel tank under the chamber through the liquid check valve, solenoid 

valve and the throttle quickly back to the tank, rapid decline in the course of the 

slider, the formation of a vacuum chamber on the Hydraulic  cylinder. And through the 

check valve oil-filled, when the trip switch SQ2 (See Figure V), YV4 was electric 

as the role of throttle, slow slide into decline by the rapid decline in the slide 

down first exposure to mold work of press brake , slide in oil under pressure to 

bend the workpiece into the speed work the slider down to pre-set position, the 

fuel tank of a mechanical stop to limit the slider down, and stop at the location, 

this time by the oil pressure relief valve back to tank.

Press the button fitted in the pannel of hydraulic press brake  to slide up SB5 (or foot pedal up the slider) is YV1, YV3 was electric oil pressure  by the solenoid valve check valve into the cylinder under the chamber push rod to slide up oil on the cylinder chamber 

through the orifice solenoid valve back to the hydraulic tank of press brake a, 

when the slider back up to the limit switch SQ1 stop contact point on the slider 

blcok when YV1,YV3 loss of power hydraulic oil overflow by magnetic valve back 

to the tank slide stop pump running in an empty state.

Remote working pressure adjustable regulator, needs to adjust the set pressure 

of each valve as follows:

No.9 Relief valve set pressure:20.5Mpa

No.8 Remote high-pressure valve set pressure: 0-20.5Mpa
