The CNC tube bending machine utilizes a microcomputer-based CNC display system, allowing for the free setting of cut lengths, quantities, and feeding speeds. It features an adjustable roller feeding mechanism with automatic pressure and vertical adjustment on both sides, enabling rapid material loading. Combined with a pin-type feeding mechanism, it effectively prevents material scratching while ensuring high precision and minimal waste. The machine's ergonomic design ensures simple, highly automated operation; this not only guarantees reliable bending quality but also significantly boosts production efficiency, overcoming the limitations of manual bending methods.
However, the complex spatial geometry of tubes makes accurate representation via design drawings difficult, and measuring standard sample tubes is equally challenging. Consequently, generating "bending programs" has become a key issue to address when using CNC tube bending machines. Currently, programs are typically created through a tedious trial-and-error process: test-bending individual sections, recording initial data, test-bending the entire tube shape, refining the data, and finally finalizing the parameters. This approach results in material waste and low efficiency.
To explore new methods—such as accelerating programming or adopting automatic computer programming—and to elevate CNC tube bending capabilities, modern machines incorporate touchscreens and CNC modules. These systems offer conversational interfaces, easy parameter setting, and large program capacities; each file supports up to 16 bending steps, and the memory stores 16 files. They achieve a bending repeatability of ±0.1 degrees, with error messages displayed instantly to facilitate quick troubleshooting. A powerful direct-acting hydraulic system ensures that thin-walled tubes or those with small bending radii do not deform during the process.
An analysis of conventional bending processes reveals that tube bending essentially consists of three basic actions: linear feeding, spatial rotation, and the bending action itself. Naturally, the process also involves auxiliary movements—such as clamping and releasing the clamp or pressure dies, and resetting the bending die. The entire bending operation is simply a combination of these basic mechanical actions performed in a specific sequence. Through extensive practical experience, the mechanics of pipe bending have been mastered, making it possible to sequence and control these basic movements to achieve the mechanization and automation of pipe-bending machines.
