I Climbing frame punching machine Causes of oil leakage at sealing parts:

Climbing frame Punching machine There are many methods to diagnose the fault of climbing punching machine,

The climbing punching machine can be simply divided into eye, nose and ear.

(1) Visual inspection is to check the working condition of climbing frame punching machine system through eyes.

1. If the oil volume in the oil tank meets the requirements, whether there are bubbles and discoloration.

2. Oil leakage at sealing part and pipe street;

3. Change of indicated value of pressure gauge and oil temperature gauge during operation;

4. Check whether the fault part is damaged, the connection is gradually falling off and the fixing parts are loose.

(2) Hearing is to listen to the hydraulic system for abnormal sound.

1. The sound of normal machine operation has a certain rhythm and rhythm and is stable.

2. Therefore, if we are familiar with and master these rules, we can accurately diagnose whether the hydraulic system works normally;

3. At the same time, according to the changes of rhythm and rhythm, and the components produced by abnormal sound,

4. Then we can determine the parts where the fault occurs and the damage degree.

5. Such as high pitched shriek, usually inhaled air;

6. The "chatter" or "gurgle" of hydraulic pump is often caused by damage of pump shaft or bearing;

7. The reversing valve makes a "wheezing" sound, which is due to insufficient opening of the valve stem;

8. The rough "clatter" may be the sound of overload valve overload.

9. If there is cavitation noise, it may be that the oil filter is blocked by dirt, the suction pipe of the hydraulic pump is loose, or the oil level of the oil tank is too low.

(3) Sniff is to smell for abnormal smell.

If there is a special smell, the construction shall be stopped immediately for inspection and testing.

2、 Debugging method of climbing frame punching machine:

1. Debug the position of the piercing head

The main function of the piercing head of the CNC climbing frame punching machine is to punch the position where stainless steel and other materials need to be punched, so its position must be adjusted accurately.

During debugging, it should be noted that when the center of the pendulum is at a low point within the measurement range, the tip of the piercing head should be at the horizontal position of the rotation axis of the pendulum.

2. Commissioning and calibration of zero point

Remove the sample splint on which the heavy lump is placed, and adjust the pointer to the place with large value,

Then place the CNC climbing frame punching machine at the position where the test starts and press the release button to make the pendulum swing,

Under normal circumstances, the pointer should be at the zero point. If not, use the zero adjustment screw to adjust.

If it is necessary to replace heavy lumps with different weights during use, the zero point shall be re adjusted.

3. Adjust pointer friction

When debugging the pointer friction force of the CNC climbing frame punching machine, first place the pointer at the zero point, and then place it at the test position,

Then let the pendulum swing by releasing the button, which means that the pointer should not exceed the zero point,

If it exceeds the limit, inject lubricating oil into the bearing of the pointer or release the spring pressure of the pointer to debug it.

The purpose of debugging the professional CNC climbing frame punching machine is to ensure that the punching machine can have better punching quality and precision, so we carefully debug the punching machine that has just been purchased or replaced with important parts, so as to obtain the ideal punching effect. At the same time, Accurate debugging is also an effective protection for the service life of the CNC climbing frame punching machine itself.
