Safety Protection for the Swing-Arm Working Area of CNC Pipe Bending Machines

When using a CNC pipe bending machine to process long pipe components, as the bending die rotates, the tail end of the pipe undergoes significant lateral swinging—commonly referred to as "tail sweeping." This process is fast-paced, involves high torque, and the hazardous area varies depending on the length of the pipe component. Traditional physical barriers not only occupy substantial workshop space but also severely impede the frequent loading and unloading of long pipe components and the replacement of dies, thereby reducing production efficiency. How to effectively prevent operators from being struck or squeezed by swinging pipe components without erecting physical barriers has become the core requirement for enhancing safety in pipe-bending workshops.

Application Logic: At a critical location beneath the bending machine’s head, a YINTAILI Technology ILS-F20 safety-grade LiDAR is deployed. The F20 performs horizontal scanning, creating an invisible “electronic safety fence” just below the plane of pipe oscillation. The shape of this area can be custom-drawn according to the maximum length of the pipe and its oscillation trajectory.
① Workpiece Protection: When the machine starts the bending process, radar activation triggers protective measures. As soon as the radar detects a person’s leg entering the hazardous swing zone, an emergency stop signal is immediately activated, causing the equipment to halt its motion instantly.
② Flexible interaction: After personnel leave the area and the system resets, the machine can quickly resume operation, realizing a seamless and safe logic of “machine stops when people enter, machine starts again when people leave.”

Technological Advantages: The F20 meets the safety standards required for metalworking machinery. Compared to safety mats, it is wear-free, easy to clean, and offers unlimited protective shapes. In contrast to light curtains, it does not require paired installation—single-sided deployment is sufficient to cover large, irregularly shaped areas. Its advanced anti-interference algorithm effectively filters out metallic reflections and arc flashes commonly found in workshop environments. Even in machining environments filled with oil mist and vibration, the F20 delivers stable and reliable active safety protection, ensuring absolute personnel safety while maximizing machine tool productivity.
