How to use hydraulic shears better?

How to use hydraulic shear? For those who use this kind of mechanical equipment for the first time, they must master it. If they do not master it well, they may not be able to use the hydraulic plate shears well. Even in the use process, due to improper operation, there will be various problems, which will affect the normal work of the plate shears. As for the hydraulic pendulum shear, let's introduce its operating procedures. We have already understood its operating methods and improved the operating procedures.

Application of hydraulic shearing machine.

Start the blade machine of the hydraulic plate shearer, and carry out several cycles of idling, so as to ensure that under normal circumstances, try to cut different thickness of plates from thin to thick, and ensure that users are familiar with the performance of the blade of the hydraulic plate shearer.

2、 In the process of trial cutting, different blade clearance must be adjusted for different plate thickness. If the blade clearance is not adjusted accordingly, the blade durability will be affected.

During the shearing process of hydraulic scissors, open the switch of pressure gauge, observe the value of oil pressure, and the shearing pressure of 12mm plate should be less than 20MPa.

4、 When leaving the factory, the pressure is adjusted to 20 ~ 22Mpa. The user must comply with this regulation. Do not pressurize the material surface beyond the regulation, causing damage to the machine.

(5) When working, the sound is balanced. If there is noise in the hydraulic switch, stop to check.

(6) When the hydraulic brake shear works, the temperature of the oil tank rises less than 60 degrees, and stops working when it exceeds 60 degrees.

2、 Operation rules of hydraulic swing shear.

A. Before work.

Before the test run, the manual barring should be used to complete a working journey, and the equipment can be started after confirming that it is normal.

For equipment with hydraulic device, check the sufficient oil in the oil tank. After starting the oil pump, check whether there is leakage in the valve and pipeline. The pressure should meet the requirements. Open the vent valve to release the air in the system.

2. Scope of work.

It is not allowed to cut and fold, trim the edge of edge material, and cut loose slit sheet and short slit sheet.

The gap between the cutter plates should be adjusted to a positive number according to the thickness of the plate, but it should not be greater than 1 / 30 of the maximum value. The cutter should be fixed firmly, and the upper and lower cutter plates should be parallel. After adjustment, it should be checked by manual turning to avoid accidents.

The blade of the cutter board should be kept sharp. If the blade becomes blunt or breaks, it should be replaced in time.

When shearing, the pressing device shall firmly press the sheet, and it is not allowed to shear without pressure.

(e) For equipment equipped with hydraulic device, it is forbidden to adjust any hydraulic valve without permission except throttling valve.

The thickness of the plate cut by the hydraulic pendulum shear should be determined according to the curve of the relationship between the ultimate strength of the plate and the thickness of the plate.

3. After the completion of the work.

The upper cutterhead should be placed at the bottom.
