How to Operate Press Brake

1.Introduction to processing Q235 Sheet Metal with Ordinary Hydraulic Press Brake Machine:

First,turn on the power and open the key switch on the control panel.Then press the oil pump start button,and you will hear the sound of the oil pump rotating.

Stroke adjustment:It is important to adjust the stroke when using the bending machine.Before bending,it is necessarey to test run the machine.When the upperdie of the bending machine 

moves to the bottom,there must be a thickness of one plate as a gap.Otherwise,it will damage the mold and the machine.Stroke adjustment can be done by electricallt or manually.

Bendng groove selection :Generally ,the bending groove width should be 8 times the thickness of the plate.For example,if you are bending a 4 mm thick plate,you need to select a groove width of around 32mm.

Back gauge adjustment:Generally,the back gauge has both electric and manual adjustment methods,similar to the shear machine.

Press the foot switch to start bending.Unlike the shear machine ,you can release the foot switch at any time.When you release the foot switch,the bending machine stops and resumes operation when you step on it again.

Maintenance of Press Brake Machine:

Before performing maintenance or cleaning the machine,align the upper die with lower die,turn off the power,and make suure it is safe when performing any other operation.

The maintenance contents are as follows:

a.Check the oil level of the oil tank every week.If the hydraulic system has been repaired,check the oil level.If the oil level is below the oil window ,add hydraulic oil.

b.The hydraulic oil used in the machine is ISO HM46 or Mobil DTE25.

c.After the new machine has worked for 2000 hours,the oil should ve changed .After that ,the oil should be changed every 4000 to 6000 hours of operation.Each time the oil is changed,

the oil tank should be cleaned.

d.The oil temperature of the system should be between 35 ℃ and 60 ℃ and should not exceed 70℃.If the temperature is too higj,it will cause the oil and components to deteriorate.

Filter:

e.The filter should be replaced or thoroughly cleaned every time the oil is changed.

f.If there are related alarms or the oil is not clean,the filter should be replaced.

g.Check and clean the air filter on the oil tank every three months and replace it at least once a year.
