Heavy Duty Hydraulic Press Brake Machines.: March 2013

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.
