The proportion of pressure instability within 5 years of use of the cutting machine is 10%, and even some new machines have pressure instability.
First of all, let’s understand what is the pressure instability of the cutting machine: in the case of not changing the knife mold, no materials, normal operation, a knife or several continuous cutting and too deep belong to the pressure instability.
The following situations are not pressure unstable:
1. Different front and rear positions in the cutting area.
2. The cutting depth of the left and right positions in the cutting area is different.
3. After changing the knife mold, there is continuous cutting or too deep cutting.
4, on the workbench pressure down sometimes can get up sometimes can not get up, and so on!
Minor pressure instability of cutting machine will cause early scrap knife die, waste time and money and have potential safety risks; serious pressure instability is very dangerous in operation, damage the knife pad, damage the pad, sometimes the knife die is pressed in the pad or even can not be called back, the cracked pad will splash the operator causing personal injury and a series of dangers.
So what causes the machine pressure instability?
1, Electrical reasons. The pressure instability caused by electrical equipment is generally poor line contact, poor relay quality or relay damage, damage of the stroke switch at the end point, and the poor quality of the time relay, etc.
2, Hydraulic system. Oil road leakage, solenoid valve damage or poor reflection, oil pump displacement instability. Note: The case shows that all electrical components have changed all hydraulic components but the fault is still. At this time, it is necessary to install the voltage stabilization system.
3, mechanical pressure instability has not been found so far, and there is little possibility of mechanical pressure instability.
Do you know the daily maintenance method of the fully automatic cutting press machine?
You will use the fully automatic cutting machine, so do you know how to maintain the cutting machine? Only the daily maintenance of the cutting machine in the use of the future will bring you higher benefits, so how to maintain it? The following is for you. Apply spring oil on the left and right ends of the cutter. In order to make the cutter smooth, if the equipment is active, check whether the switch and the cam are normal and whether the screw is loose, then twist the cam, and then check whether the spring is too tight before cutting every day. If the cutting machine is blunt, the cutting machine needs to use a grinding knife, if not sharpened knife, there will be continuous cutting, affect the effect of the use of the effect will also lead to the use of efficiency greatly reduced! And the best installation position of the cutting machine is closely close to the printing press.
The above is the maintenance method of the automatic cutting machine, I hope this article can bring help to you.
