The reason why the nitrogen gas cannot be added to the hydraulic shearing machine and the precautions for the blade

by:WORLD     2022-08-15

Hydraulic shearing machine is a machine that uses a reasonable blade gap to apply shearing force to metal sheets of various thicknesses, so that the sheets are broken and separated according to the required size. The world press machine will introduce its related knowledge to you.

What are the reasons why the hydraulic shearing machine cannot be fed with nitrogen?

First, you must first understand the type of hydraulic shearing machine you are using, whether it is a pendulum type or a gate type. The hydraulic gate shearing machine only needs to be operated relatively easily. Just press the operation button to add nitrogen.

Second, check the nitrogen bottle used to see if the nitrogen inside is full.

Third, check the pressure gauge on the hydraulic shearing machine to see if the hydraulic shearing machine switch is turned on. If it does not open, check whether the switch is blocked, which is related to whether nitrogen can be added in

Fourth, the reason why nitrogen cannot be added is that the tool holder on the hydraulic shearing machine 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, no matter how much nitrogen is flushed, it is useless.

Precautions for hydraulic shears blades:

The hydraulic shearing machine blade model can be divided into hydraulic pendulum shearing machine blade and hydraulic guillotine shearing machine blade. The shear plane can obtain good straightness and parallelism to ensure the high quality of the workpiece.

First of all, when using the blade of the hydraulic shearing machine, it is not allowed to cut the superimposed steel plate material, it is not necessary to trim the edge of the raw steel plate material, and it is not necessary to cut the narrow plate that is not tightly compressed. Not only that, the cutting edge of the shearing machine blade should be kept It is sharp. Once it becomes dull or cracked, it should be replaced or ground in time. The gap between the shears is also very important. It is best to adjust it according to the thickness of the sheet to keep it within the allowable range. Inside, when the hydraulic shearing machine is shearing, the pressing device should firmly compress the sheet, and it cannot be cut in a state where it is not tightly pressed, so as to avoid accidents.

The above is the relevant introduction, I believe that everyone has a certain understanding of the hydraulic shearing machine.
