Introduction to Classification and Working Principle of Shearing Cuttimg Machines

Buying the right sheet cutting machine is more important than buying a good one. Understanding the classification and pros and cons of different types of sheet cutting machines can help you make a more informed decision and reduce the hassle in your purchasing process.

sheet cutting machines are generally classified into two major types: CNC hydraulic sheet cutting machines and mechanical sheet cutting machines. However, what customers care about is the selection based on economic practicality. How can you choose a sheet cutting machine effectively? It is selected based on the thickness of the plate, which we refer to as thin plate, medium-thick plate, and thick plate, respectively. They are further divided into thin plate sheet cutting machines, medium-thick plate sheet cutting machines, and thick plate sheet cutting machines.

Working principle of sheet cutting machines

A sheet cutting machine is a machine that cuts sheets by moving an upper blade back and forth in a straight line relative to a lower blade. By using a scientifically reasonable blade gap, the upper blade in motion and the fixed lower blade apply a shearing force to sheets of various thicknesses, forcing them to break apart according to the customer's desired dimensions.

Differences between CNC hydraulic sheet cutting machines and mechanical sheet cutting machines

Different transmission methods: CNC hydraulic sheet cutting machines are driven by hydraulic power, while mechanical sheet cutting machines are driven by mechanical power.

Different cutting principles: CNC hydraulic sheet cutting machines adopt the swing cutting principle, while mechanical sheet cutting machines adopt the gate cutting principle.

Different precision control effects: CNC hydraulic sheet cutting machines are programmed for control, while mechanical sheet cutting machines are manually adjusted.

Classification of sheet cutting machines according to their applications

Special purpose sheet cutting machines

It is used in conjunction with other equipment to complete special purposes:

Cold bending forming line sheet cutting machine: a special purpose sheet cutting machine configured on production lines such as car longitudinal beam cold bending lines, car side plate production lines, and color steel plate forming lines;
Steel structure production line sheet cutting machine: used for automatic cutting and breaking of angles and H-section steels;
Plate leveling line sheet cutting machines: designed for high-speed cutting requirements in conjunction with the production line on the plate decoiling leveling line, generally consisting of hydraulic high-speed sheet cutting machines for thick plate lines and pneumatic sheet cutting machines for thin plate lines; high-speed lines are equipped with flying shears for continuous production and high efficiency.

Inclined blade sheet cutting machines

The upper and lower two blades of the sheet cutting machine form an angle, and the upper blade is generally inclined. The cutting force of the inclined blade sheet cutting machine is smaller than that of the flat blade sheet cutting machine, so the motor power and overall weight are greatly reduced, making it the most commonly used type in practical applications. Most sheet cutting machine manufacturers produce this type of sheet cutting machine.

Flat blade sheet cutting machines

The cutting quality is good, and the distortion and deformation are small, but the cutting force and energy consumption are high. The upper and lower two blades of the sheet cutting machine are parallel to each other and are commonly used for the initial cutting of hot rolling billets and slabs in the rolling mill. According to their cutting methods, they can be divided into up-cutting type and down-cutting type.

Multi-purpose sheet cutting machines

Combined punching and shearing machines: capable of both cutting sheets and cutting profiles, commonly used in cutting processes;
Plate bending and coil shearing machine: capable of cutting and bending on the same machine.

The above is the full content of the sheet cutting machine. If you happen to need to purchase a sheet cutting machine, be sure to determine in advance what kind of product you want to process, understand your own needs, and then make the purchase.
