The hydraulic shearing machine has 3 types: CNC hydraulic Shearing machine, NC hydraulic shearing machine, and manual metal shear.

Also, we can classify it as a swing beam shearing machine, a Guillotine shearing machine, and shearing machine parts.

1. A swing beam shearing machine has a blade that pivots around a fixed point. the swing shear cutting blade design has two side edges.
2. the guillotine shear blade is almost parallel to the fixed blade for straight slide cuts. and guillotine shear cutting blade design has 4-sided edges.

Tensile strength can be defined as the maximum stress that a material can bear before breaking when it is allowed to be stretched or pulled.

A hydraulic shearing machine is a kind of machine that uses a moving upper blade and fixed lower blade to apply shear force to metal plates of various thicknesses by using reasonable blade clearance. so as to break and separate the plates according to the required size.

The hydraulic Shearing machine is powered by a hydraulic system. The force from the hydraulic system puts the desired material against the steel plate. The cut is controlled by a squaring arm that allows a sheet of metal to be placed in a precise location. Shearing is performed by cutting through a piece of sheet metal with a blade that’s most often affixed to a tool or machine.

1. First of all, know well the type of hydraulic sheet metal shears you use: swing beam shear or guillotine type. The operation of hydraulic guillotine shears is relatively simple. You can add nitrogen as long as the relevant operation button is pressed.
2. Secondly, check the nitrogen cylinder used: whether the nitrogen is full.
   Thirdly, check the pressure gauge on the steel metal shearing machine: check whether to turn the switch of the metal shear machinery. If not, check if the switch is blocked. This is also the key to adding nitrogen successfully.
3. Finally, there is another situation: the cuter tool holder on the plate shears has not been put up yet. At this time, you need to check the main cylinder of the steel cutter: stuck or not. If stuck, it’s useless to flush more nitrogen.
