What is a  shearing machine?

A shearing machine is an industrial tool used in metalworking to cut sheet metal into precise sizes and shapes by applying shear force.  The hydraulic Shearing machines are essential in industries such as automotive, aerospace, construction, and sheet metal fabrication. The metal shearing machines provide accurate, straight cuts with minimal burrs and deformation. The shear cutting machine adopts the latest technology and high performance for quick and repetitive cutting, improving productivity. Our stable and robust metal plate shearing machines feature all-welded structures for top-quality cutting. It offers parts & accessories with one top blade, a lower die, and the standard square arms. We offer the shearing solution for mild steel, aluminum, and stainless steel. As one of the top cut-off (shearing) device suppliers, if you need an automatic, mechanical shear, or hydraulic shear machine, please contact us for more solutions today.

Core Components & Function

The sheet metal shearing machine consists of a frame, power system, working holder, shear blades, and back gauge. The sheet metal shearing machine works by applying a machine shear force to the material, which causes it to yield and ultimately fracture along the cutting line. The machine shear operations are performed by two cutting blades with a straight cut or a circular arc. First, the hydraulic metal shear machine uses a working holder to clamp the sheet plate, then the upper blade moves down and applies force to the material, which is then cut by the shearing action of the blades.  It can break sheet metal plates into required lengths with a fixed cutting angle. The cutting blade gap can be adjustable according to the wide variety of material thicknesses.

FAQ- Engineering Quick Answers

A shearing sheet metal machine is a manufacturing tool to cut metal sheets by applying force along a straight line. It operates against a ledger blade, which moves up and down, creating the cuts into smaller pieces. The sheet metal shear machines are designed to cut mild steel and stainless steel with high precision.

The hydraulic steel shearing machine includes the following:

  • CNC shearing machine(Automatic Shearing machine),
  • NC hydraulic shearing machine
  • Manual metal shearing machine(mechanical machining shears).

or we can classify the sheet metal shear machine as:

  •  Swing beam shearing machine
  • Guillotine shearing machine,
  • Hydraulic sheet shearing machine

The sheet metal shearing machines are used in the metalworking industry to cut parts into the desired dimensions for further processing. Shearing in sheet metal is performed by cutting through a piece of sheet metal with a blade that's most often affixed to a tool or machine.

 

Cutting Action:

Swing Beam Shear moves with the upper blade in a circular arc. The sheet metal is placed on the stationary lower blade, and the swinging motion of the upper blade cuts through the material. It has two side cutting edges.

SwingBeam Shear blade design

Guillotine shear makes straight cuts, the upper blade moves up and down uprightly and the bottom blade is fixed on the worktable. The sheet metal is positioned between the blades, and the downward movement of the upper blade cuts through the material. It has four side cutting edges.

Guillotine-shear blade design
Cutting Angle:

Swing Beam Shear: The swing beam shear's cutting angle is fixed. This means that the angle at which the upper blade swings remains constant during the cutting process.

Guillotine Shear machine: Guillotine machine shears can have an adjustable cutting angle. This allows for greater flexibility in cutting different materials and achieving specific cutting requirements.

 

Cutting Accuracy:

Swing Beam Shear: Swing beam shears generally provide higher cutting accuracy due to their swing beam design. The swinging action helps distribute the cutting force evenly, resulting in clean and precise cuts.
Guillotine Shear: Guillotine shears also offer good cutting accuracy, but they may not be as precise as swing beam shears, especially when cutting thicker or heavier materials.

How to Sharpen Shear Blades

The tensile strength of an Industrial shearing machine be defined as the maximum stress that a material can bear before breaking when it is allowed to be stretched or pulled.

Hydraulic shearing machine is a kind of machine that uses a moving upper blade and fixed lower blade to apply a 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.

First of all, know well the type of hydraulic plate 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 pressed.
Secondly, check the nitrogen cylinder used: whether the nitrogen is full.
Thirdly, check the pressure gauge on the steel metal shearing machine: check whether 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.
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.
