3-х валковая листогибочная машина

The structure of 3 roll plate bending machine usually includes base, frame, control panel and three working rollers. The base provides stability and support, and the frame connects the various components and bears the forces during processing. The control panel is used to operate and adjust the bending parameters, such as the position and speed of the rollers. In addition, modern 3 roll plate bending machines are also equipped with hydraulic systems or mechanical transmission systems to achieve efficient and precise bending operations.

Three roll plate bending machine can be divided into two types: symmetrical and asymmetrical. The upper roller of the symmetrical 3 roll plate bending machine is located at the center of the lower roller, and is usually used in applications that require high precision and symmetrical bending. The upper roller of the asymmetrical 3 roll plate bending machine is located on one side, and the lower roller is divided into two parts, which is suitable for processing plates that require pre-bending or complex shapes.

Due to its symmetrical structural design, the symmetrical 3 roll plate bending machine can better solve the springback and precision problems of the steel plate. This uniform force distribution enables the symmetrical machine to maintain high processing accuracy when processing arc-shaped or conical workpieces.

Although the asymmetrical 3 roll plate bending machine has a higher bending efficiency, due to its structural characteristics, it may have uneven force problems in some cases, especially when bending complex shapes, and additional adjustments or auxiliary equipment are required to ensure processing accuracy.

• Used to manufacture curved parts of ship hulls, such as hull plates, decks, etc.
• Used to manufacture curved parts of pipes, tanks and other equipment.
• Used to bend parts such as boiler shells and flues.
• Used to manufacture curved parts such as cement kiln linings and pipes.
• Used to produce curved parts of various mechanical equipment, such as machine tool guides, pump housings, etc.
• Used to manufacture curved parts in building structures, such as roof beams, columns, etc.
• Used to manufacture curved parts of transmission towers, such as towers, beams, etc.
• It is also used in other fields, such as water conservancy projects, mining machinery, chemical equipment, etc.

The working principle of the 3 roller plate rolling machine is based on the geometric principle of "three points form a circle". Through the relative position change and rotation movement of the three rollers, the metal plate undergoes continuous plastic deformation and is bent into the desired shape.

Step 1: According to the plate thickness and the required bending radius, adjust the distance between the upper roller and the lower roller. Usually, the distance between the upper roller and the lower roller is slightly greater than the plate thickness.

Step 2: After feeding the plate into the three-roll bending machine, press the start button, the motor drives the lower roller to rotate, and the hydraulic system or mechanical transmission system controls the upper roller to move vertically and apply pressure.

Step3: After the plate is bent under the action of the three rollers, the finished product is taken out through the unloading device.

The 3 roller plate bending machine adopts a unique triangular roller structure configuration, which can achieve high-precision bending operations. Its design ensures the stability and consistency of the plate during the bending process, thereby reducing dimensional deviations and surface defects.

The 3 roller plate bending machine can handle plates of different thicknesses and materials, including stainless steel, carbon steel and aluminum, and can achieve bending in a variety of shapes, such as cylindrical, conical and curved.

Compared with the more complex 4 roller plate bending machine, the 3 roller plate bending machine has a simpler structure and lower cost, but it can still provide efficient and reliable performance.
