Manhart What is the specific working principle of CNC bending machine?

The working principle of CNC bending machine is mainly reflected in the following key points:
1. Equipment structure and design:
-A CNC bending machine usually consists of two upper and lower rollers and an adjusting wheel, which work together to achieve bending of metal sheets through specific design.
-The upper roller can be moved up and down by hydraulic or mechanical means to adjust the bending radius of the metal sheet.
-The adjustment wheel is used to adjust the position of the middle roller to accommodate metal sheets of different thicknesses.
2. Processing process:
-After the metal sheet enters the bending machine, it will be rolled and pressed through the collaborative action of three rollers.
-The upper roller will press down on the board to fit the lower roller and form the desired curved shape.
-The adjustment wheel is adjusted according to the thickness of the board and the required bending radius.
3. Application of Numerical Control Technology:
-The CNC bending machine uses industrial computers or specialized control systems to precisely control the movement of the rollers to achieve high-precision bending processing.
-Through programming, multiple bending shapes and parameters can be preset to achieve automated and efficient production.
4. Technical parameters and accuracy:
-The technical parameters of CNC bending machine include power, voltage, roller speed, maximum diameter of roller mold, roller diameter, shaft spacing, etc.
-These parameters determine the processing capability and accuracy of the equipment, such as the roller speed affecting processing efficiency, and the maximum diameter of the roller mold determining the maximum width of the machinable sheet metal.
-Through a high-precision control system, the CNC bending machine can achieve extremely high machining accuracy, such as the repeated positioning accuracy of a certain model of CNC bending machine on the Y-axis push rod can reach ≤ 0.01mm.
In summary, the working principle of a CNC bending machine is to achieve high-precision and high-efficiency bending of metal sheets through the collaborative action of three rollers, combined with high-precision control of CNC technology.
