The hydraulic shearing machine is driven by hydraulic pressure, the upper blade moves, the lower blade is fixed, and various metal plates are sheared through the blade gap. What should we do when the hydraulic shearing machine is broken?
Check whether the circuit of the hydraulic shearing machine and the directional valve are loose or the valve core is stuck; if the slider can not be lowered, you only need to repair or replace the slider and tighten the fixing screw. But at the same time, you have to check the actual status of the hydraulic system of the shearing machine, and observe whether there are problems with the system pressure, speed, oil, leakage, vibration, etc.
The problem can also be checked by listening to the sound of the device; if the bad phenomenon occurs because the sealing system is damaged, only the sealing ring needs to be replaced.
It is also necessary to check the actual status of the hydraulic system of the shearing machine and observe whether there are problems with the system pressure, speed, oil, leakage, vibration, etc.
For details, please refer to the following methods:
a. hydraulic shearing machine clearance adjustment
Press and hold the two buttons with larger and smaller cutting angles. Place the blade on the machine tool and stack the lower blades at 3-5mm at both ends. Adjust the minimum clearance.
After mediation, the machine tool is filled with oil once, the upper tool post is being reset, and the key is pulled out.
To the cutting position, normal use.
b, Turn with hydraulic shearing machine
By holding down the button with a smaller cutting angle, the upper blade holder is adjusted to zero. Then remove the table guide, loosen the screws that hold the blade, and then take out the blades in sequence. Then, loosen the screw that fixes the upper blade, and take out the upper blade in sequence.
Then, install the blade first, and then install the blade. Search for smoothness at the interface between the blades. Finally, fix all blade screws and install the guide plate.
2. How to replace the pipeline seal of hydraulic shearing machine?
First, place the upper knife holder of the hydraulic shearing machine at the bottom dead center, cut off the power supply of the machine tool, loosen the oil reservoir of the oil leakage part, take out the damaged seal, apply a layer of butter in the joint groove, and install a new seal in the groove Parts and oil reservoir
3. Does the hydraulic shearing machine produce working pressure?
a. The accuracy of forward and reverse rotation of the shearer motor and oil pump is studied.
b. Clean the safety valve slide valve of the shear.
c. Two four-way solenoid valves clean the shear in the hydraulic system.
d. The hydraulic shearing machine slowly returns
e. Cut off the oil again.
f. Check the adjacent parts of the shear for signs of oil leakage and leakage.
Finally, check the nitrogen pressure of the accumulator of the shear. The normal nitrogen pressure is 4-5 MPa. Before starting the machine, you should carefully check whether the work station is properly arranged and whether there are any abnormalities in the workbench or mold area. After confirming that there is no abnormal situation, the machine tool can be started to work.
As long as you master the normal use of the shearing machine, you can help you use the machine more conveniently, and you will naturally get a standard size plate.
