[0003] Improve production efficiency: The parts bending machine adopts automated operation, which reduces the intensity of manual labor and improves production efficiency. Ensure the processing accuracy of parts: The parts bending machine adopts a high-precision CNC system to achieve precise control and ensure the processing accuracy of parts. Diversified processing capabilities: The parts bending machine is suitable for various parts bending, bending, punching, shearing and other processing technologies, and has strong processing capabilities. Optimize part design: The parts bending machine can easily realize the bending and bending of parts, providing more possibilities for part design. Improve the quality of part connection: The parts interface processed by the parts bending machine is flat and smooth, which is conducive to improving the quality of part connection and reducing water leakage, air leakage and other phenomena.

Usually, when the bending machine adapts to bending dies of different sizes, the bending dies are clamped and fixed by installing bolts or screws with a clamp. As a result, when the bending dies are replaced, the mounting bolts or screws need to be removed before the bending dies can be replaced, which makes the replacement of the bending dies more cumbersome, thereby affecting the use efficiency of the bending machine.
