Operation instructions for precision four-column hydraulic cutting machine-Dongguan Heavy Cutting Machine Co., Ltd. Precision four-column hydraulic cutting machine operation instructions-Dongguan Heavy Cutting Machine Co., Ltd.



First, the precision four-column hydraulic cutting machine installation



1. Fix the machine level on the flat concrete floor, check whether the parts of the machine are in good condition and the line is smooth and effective.



2. Remove stains from the upper platen and the work surface.



3. Inject 68# or 46# anti-wear hydraulic oil into the fuel tank. The oil surface should not be less than 25mm.4. Connect the 380V three-phase power supply. Press the oil pump to start.







Button to adjust and keep the motor turning in the same direction as the arrow.







Second, the precision four-column hydraulic cutting machine operation instructions



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. Lay the push-pull plate, rubber plate, workpiece, and die in the middle of the workbench in order.



4. Pair of 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 spin button to decrease 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 stroke is reduced, and the stroke can be 50-200mm (or 50-







Free adjustment within the range of 250mm), the normal pressure is about 50mm at the top of the die. Special attention: every time you change the die, the workpiece or







When the pad is used, the stroke must be set again. Otherwise, the die and the pad will be damaged.







Third, the precision four-column hydraulic cutting machine safety matters:



1. In order to ensure safety, it is strictly forbidden to extend the hand and other parts of the body into the punching area during operation. The power must be turned off before maintenance and in the blanking area.







Padded in wooden blocks or other hard objects to prevent the upper pressure plate from getting out of control after the pressure is released, causing accidental personal injury.



2. Under special circumstances, when the upper pressure plate needs to be immediately raised, press the reset button. When stopping, press the power brake button (red button).







The whole system stopped working immediately.



3. When operating, you must hit the two buttons on the pressure plate with both hands, and do not change one hand or pedal operation at will.







Fourth, the precision four-column hydraulic cutting machine maintenance:



Always keep the machine clean, the oil filter net is cleaned once a month, the hydraulic oil is changed once a year, and the oil level in the machine should be checked before work.







The hydraulic fluid of the same grade should be added to the fixed liquid level and should not be mixed. When cutting, the workpiece should be placed in the center of the work area to make the machine







The force is evenly distributed, extending the service life of the machine from the surface.
