how do hydraulic cutting machines work

- Feb 20, 2019-

1. First turn the cutting depth controller (fine tuning knob) to zero.


2. Turn on the power switch, press the oil pump start button, run for two minutes at no load, and observe whether the system is normal.


3. Stack the push-pull plate, rubber plate, workpiece and die in the middle of the table.


4. Pair the die (die setting).


(1)Loosen the handle of the knife and naturally lower the bottom and lock it.


(2)Turn the switch to the right and prepare for trial.


(3)Double-click the green button to make a trial, and the punching depth is controlled by fine tuning.


(4)Fine-tuning: Turn the fine-tuning button to reduce the left-hand rotation and the right-hand rotation.


(5)Stroke adjustment: Rotating the rise height controller, the right-hand stroke is increased, the left-hand rotation stroke is reduced, and the stroke can be freely adjusted within the range of 50-200mm (or 50-250mm). In normal production, the upper pressure is about 50mm from the top of the die. It is appropriate.


Special Note: 

Each time the die, workpiece or pad is replaced, the stroke must be set again. Otherwise, the die and pad will be damaged.
