What is a Shearing Machine?

Shearing machine definition: Shearing machine uses a moving upper blade and a fixed lower blade to apply shearing force to metal sheets of various thicknesses by using a reasonable blade gap to make the sheets break and separate according to the required size. 

The shearing machine is a kind of forging machinery, and its main function is the metal processing industry. The products are widely used in aviation, light industry, metallurgy, chemical industry, construction, shipbuilding, automobile, electric power, electrical appliances, decoration and other industries to provide special machinery and complete sets of equipment required.

How Dose the Working Principle of a Shearing Machine Work?

Shearing machine is a machine that uses one blade to reciprocate linear motion relative to the other blade to cut the plate.

The shearing machine after shearing should be able to ensure the straightness and parallelism of the shearing surface of the sheared sheet, minimize the deformation of the sheet, and obtain high-quality workpieces.

The upper blade of the shearing machine is fixed on the knife holder, and the lower blade is fixed on the worktable. The worktable is equipped with a holding ball to prevent the board from being scratched when sliding on it.

The back gauge is used to position the plate, and the position is adjusted by the motor.

The pressing cylinder is used to hold down the sheet to prevent the sheet from moving during the shearing process.

Guardrails are safety devices to prevent industrial accidents. The return journey generally relies on nitrogen, which is fast and has little impact.

What Are the Classifications of Shearing Machines?

Classification of shears: General shears can be divided into pedal type (manpower), mechanical shears, electric shears, hydrualic swing shears, and guillotine shears.

  • According to the operation of the shearing machine, we can be divided into:

    Mechanical shearing machine is divided into: upper drive and lower drive

    Hydrualic shearing machine is divided into: pendulum shearing machine and gate shearing machine

  • According to the cutting method of the shearing machine, it can be divided into linear shearing machine and circular shearing machine.

    Linear shears are used to cut metal thicker than 2mm, they are operated by hydrualic power or manual machines to cut thinner metal.

    Circular shears are used to cut circular blanks and rings from metal and are driven by electric motors. The best metal types for shearing are bronze, aluminum, brass and mild steel. Metal shearing is cost-effective and easy, so it is preferred in industry and even in the home.

  • According to different designs, shearing machines can be divided into the following types:

    1.Bench Shearing Machine

    The machine is mounted on a tabletop to increase its mechanical capabilities. It is used to cut rough shapes of medium-sized metal. However, small bench shears come with ground cutting blades that are lightweight for clean and quick cuts.

    2.Guillotine

    Mechanically driven guillotine shears workflow: The material to be cut is first squeezed with a plunger, the moving blade descends and shears the metal. Electric shears consist of a shearing table to place the material to be sheared, a holding device to keep the material in place to avoid movement, a measuring device to ensure the material is in the correct position, and upper and lower blades for cutting .

    3.Power shears

    These types of shears are powered to shear large pieces of metal, no matter the size. Alternatively, they can be hydrualically driven to cut metal that is too bulky to transport.

    4.Throat

    This means that the metal being cut can move freely around the cutting blade, so it is flexible. It is used for complex cuts and curves.

What parts and units does the shearing machine consist of?

A shearing machine typically consists of the following parts and units:

  • Bed or base

    This provides a stable foundation for the machine. The entire body of the machine is strong, durable and reliable.

  • Fixed blade

    This is attached to the bed and remains stationary during the cutting process. It serves as the stationary cutting edge.

  • Moving blade

    This is mounted on a sliding mechanism and moves back and forth across the fixed blade to perform the cutting action. It serves as the movable cutting edge.

  • Hold-down system

    This clamps the workpiece in place during the cutting process. It helps to keep the workpiece stable and prevent it from moving during the cutting process.

  • Guiderail system

    This helps to align the workpiece and keep it in position during the cutting process. It helps to ensure that the workpiece is cut at the correct angle and location.

  • Actuating mechanism

    This controls the movement of the moving blade. It can be a foot pedal or hand lever that the operator uses to start and stop the cutting process.

  • Cutting angle adjustment mechanism

    This allows the operator to adjust the angle of the blades relative to each other. It allows the operator to adjust the angle of the blades to suit the specific cutting requirements of the workpiece.

  • Safety guards and interlocks

    These are designed to protect the operator from the cutting action. They are usually placed around the blades and other moving parts of the machine to prevent accidents.

These are the main parts of the shearing machine, their functions are as described above, depending on the specific design of the machine, additional parts may be present.

 

How to Use the Shearing Machine

The following situations may occur during the use of the plate shearing machine:

  1. Start the shearing machine for idling several cycles, to ensure that under normal conditions, try to shear different thickness of the sheet, from thin to thick. Ensure users are familiar with the shearing machine performance.

  2. The test shear plate thickness must be adjusted to different blade clearance. If the blade clearance is not adjusted, the durability of the blade will be affected.

  3. Open the pressure gauge switch and observe the oil pressure value during the shearing process. The pressure should be less than 20MPa when cutting 12mm plate. The pressure of the remote pressure regulating valve No9 is set at 20-22mpa when it leaves the factory. The user must abide by this regulation and shall not increase the pressure for cutting beyond the specified material surface, resulting in machine damage.

  4. Sound balance during operation. Stop the shearing machine for inspection if there is any noise.

  5. When the plate shearer operates, the temperature of the fuel tank increases. 60 degrees, over which the power off rest.

What is the difference between shearing and die cutting?

If you are familiar with the metal fabrication process, you may be wondering what is the difference between shearing and die cutting. In fact, they are both cutting or finishing processes that involve using a blade to remove excess material or create the desired shape for sheet metal. The main difference is that shearing uses straight edged blades, whereas the blades used in die cutting are curved.

Advantage

As we mentioned in the opening paragraph, shearing has become a popular and accepted practice in metal fabrication. In fact, this method has many distinct advantages.

First, the metal can be sheared without heating. This process is usually carried out at room temperature or when the metal is cold.

Second, it produces far less waste than other manufacturing practices. This allows manufacturers to save on cleaning costs and perform the process faster.

Finally, shearing can be used on a variety of metals, including stainless steel, bronze, aluminum, copper, and iron, to name a few.

Shortcoming

While shearing has many significant advantages, there are also some potential disadvantages to be aware of.

First, exceptionally hard metals like tungsten cannot be sheared.

Second, shearing can cause the stainless steel plate to deform if not handled carefully.

 

The advantages of the plate shearing machine before feeding are as follows:

  1. Matched with the ordinary shearing machine, compared with the rear stopper positioning more, can completely replace manual, mainly used in various sizes of plate cutting, blanking, high efficiency, blanking, can achieve automatic programming, automatic positioning, automatic cutting, automatic feeding, automatic return and other functions.
  2. Protection function
    • Over-limit protection, when the travel to the limit will automatically stop the movement, to avoid collision.
    • Self-diagnosis protection function, when the software, system or electrical failure will automatically alarm, remind check and elimination.
    • Air pressure protection function, when the air pressure is too low will alarm and stop working, to avoid damage to pneumatic components.
    • Voltage protection function, when the voltage fluctuation is too large, will automatically alarm and stop working, avoid damage to the servo system, electrical.
  3. Components and software program, choose pneumatic automatic clamp, clamping force is large, stable feeding; Easy to operate.
