First, definitions and principles

A plate bending machine is a machine that bends sheet metal to achieve the desired shape. It mainly uses mechanical force and liquid pressure to bend the metal sheet along the bending axis to form the desired shape. The plate rolling machine is a machine that rolls the metal sheet along a certain curve and uses the force of the roller to form the required shape.

Second, the scope of application

Bending machine and rolling machine are different in the scope of application. The plate bending machine is mainly suitable for simple bending or bending of metal sheets, and is suitable for small batch production, such as processing board boxes, ventilation pipes, etc. The plate rolling machine is suitable for long and thin metal sheets, and is widely used in the manufacturing of steel structures, aerospace, construction and other industries.

Third, the difference

1. Different technical principles: the plate bending machine mainly achieves the required shape by bending the metal sheet, while the plate rolling machine rolls the metal sheet and uses the power of the roller to form the required shape.

2. The scope of application is different: the bending machine is suitable for small batch production and simple metal sheet processing, while the rolling machine is suitable for mass production and long and thin metal sheet processing.

3. Different machine structure: the structure of the bending machine is relatively simple, mainly composed of the main machine, auxiliary shaft, workbench and so on. The structure of the plate rolling machine is relatively complex, mainly including the upper and lower roller shaft, driving device, foot wheel, transmission system and so on.

4. Different processing forms: the bending machine mainly processes the bending and bending shapes, while the rolling machine can process some established complex shapes such as semi-circle or full circle.

In summary, although the plate bending machine and the plate rolling machine are metal plate processing equipment, there are great differences in their principles, scope of application, processing forms and so on. In practical applications, the appropriate equipment should be selected according to their needs.
