The reason why nitrogen cannot be added to hydraulic shears and the precautions of the blade


The hydraulic shearing machine is a machine that applies a shear force to metal plates of various thicknesses by using a moving upper blade and a fixed lower blade, using a reasonable blade gap, to break and separate the plates according to the required size. Here are some related knowledge for everyone.

What are the reasons why nitrogen cannot be added to the hydraulic shears?

1) First, you must know the type of hydraulic shears you are using, whether it is swing beam type or guillotine type. The hydraulic guillotine shears are relatively simple to operate, as long as you press the operating button, you can add nitrogen

2) Second, check the nitrogen cylinder, whether the nitrogen inside is full

3) Third, check the pressure gauge on the hydraulic shears to see if the hydraulic shears switch is turned on. If it is not turned on, check whether the switch is blocked, this is related to whether nitrogen can be added in.

4) Fourth, there is another reason why nitrogen can't be added, it’s that the tool holder on the hydraulic shear has not yet come up. At this time, it is necessary to check whether the main cylinder of the hydraulic shearing machine is stuck. In this case, even more nitrogen is useless.

the precautions of the blade:

Hydraulic shears blades can be divided into hydraulic swing shears blades and hydraulic guillotine shears blades. As a very important shearing and forging machinery accessory, shear blades are widely used in various fields. The shear surface can obtain good straightness and parallelism, ensuring high quality of the workpiece.

First of all, when using the hydraulic shear blade, it is not allowed to cut the laminated steel plate material, there is no need to trim the edge of the raw steel plate, and to cut the narrow plate that is not tight. Not only that, the cutting edge of the shear blade should be kept sharp, if it becomes dull or cracked, it must be replaced or reground in time. The gap between the shears is also very important. It is best to adjust according to the thickness of the sheet to keep it within the allowable range inside, when the hydraulic shearing machine is working, the pressing device should firmly press the sheet, and can not cut under the state of not being tight, so as to avoid accidents.
