Main Working Principal Of Hydraulic Shearing MAchine

Working  Principal of shearing machine by Ravi Industrial Corporation 
  



                               Working principle.

Hydraulic Shearing machine

Shearing  machine adopt double-cylinder hydraulic system , which is driven by  upper blade stilted
with  compress nitrogen return cylinder and do downward    cutting action,
 complete cut, then lift upper blade stilt by nitrogen return cylinder

Hold down: First pedal switch of the shearing machine  give off transmation  signal to electrical system, control action of electromagnetic relief valve , hydraulic oil pressure increased gradually    under the control of hydraulic valve, first drive hold down oil cylinder pinch plate.


Cutting: Hydraulic oil pressure of system increase to a certain amount, two cut oil cylinder overcome compression nitrogen resistance inside nitrogen return cylinder, started descending completed shearing action. Shearing action completed.

Return 

 Electromagnetic valve loss of power under the control of electrical system, hydraulic system began to load relief. Nitrogen return cylinder overcome gravity on the turret lifted upper blade rest until the up dead center.

 Steps to use Hydraulic Press Brakes Safely For Bending From Ravi Industrial Corporation

From www.pressbrakes.in

-->

l  Bending sheet metal should be placed in the middle of the Press Brake  Machine Bed the 

press brake should not be unilateral by the load so as not to affect the accuracy of the 

workpiece and the Hydraulic Press Brake if some parts do need to unilateral work, the load 

shall not exceed the Press brake nominal power of 1/4 on both sides of the same time and 

must bend to address the problem of unilateral load. Plus N32-N46 tank hydraulic oil, the 

first use of oil should be replaced after three months 1-2times. Working oil temperature 15  

℃ -60 ℃ and regular cleaning of the inlet combfilter to keep oil smooth otherwise the pump 

will empty suction pipelin vibration.

l  Adjust the slide stroke the slider first stop should be the upper limit position of the Press 

Brake (see figure III, IV) start to adjust motor block, block will move up and down, adjust the 

maximum distance 110mm, Therefore to continue to observe phenomenon if unusual

should immediately stop checking.

These are the few steps to be taken care while working on Hydraulic Press Brake Machine

Safe Use of Technology and Hydraulic Press Brake Maintenance

Any operation and maintenance personnel of the Hydraulic press brake  must be carefully

 

read this manual carefully understand the contents of the specification as long as strictly act 

according to law then we will receive satisfactory results in maintaning  the Hydraulic  Press Brake.

l  The workpiece bending forces are not allowed to be greater than the nominal power of the 

   Press Brake

.

 In order to mold die  durability  of the press brake not because of improper because the 
    width of bending 

sheet metal damage especially in narrow bending sheet metal in press brake 

the system should be appropriate to reduce the pressure of work according to the 

thickness of sheet metal bending mode to select the appropriate port,die size is 

generally equal to or greater than the population eight times the thickness of sheet 

metal sheet metal bending force from the tableor a bending force formula derived 

workpiece bending force of the hydraulic
