Auxiliary Equipment for Laser Pipe Cutting Machines in Cutting Spiral Welded Steel Pipes—Laser Displacement Sensors
The Main Challenges Faced by Laser Pipe Cutting Machines When Cutting Spiral Welded Steel Pipes
Incomplete Cutting: This issue may arise from mismatches between the laser nozzle and the thickness of the processed pipe, setting the laser cutting speed too fast, contamination of laser lenses, or improper focal adjustment.
Enhancing Laser Pipe Cutting Efficiency: The Role of Laser Displacement Sensors in Spiral Welded Steel Pipe Processing
As the spiral welded steel pipe rotates and the cutting torch begins its work, the laser displacement sensor fixed on the cross arm plays a crucial role. Its specific functions include:
Accurate Distance Measurement and Dynamic Adjustment: By emitting a laser and receiving the signal reflected back from the surface of the steel pipe, the sensor can accurately calculate the distance between the laser head and the pipe surface. This data is essential for maintaining the optimal working gap between the cutting torch and the pipe, helping to achieve efficient and accurate cutting.
Smart Automatic Adjustment and Instant Feedback: If the pipe shifts position during rotation, the laser displacement sensor quickly detects the change and, through its integrated feedback system, instantly adjusts the cutting torch's position, ensuring continuity and consistency in cutting.
Safety Monitoring Mechanism: In addition to the above functions, the laser displacement sensor also has a safety monitoring function. If it detects an abnormal pipe position or an excessively close distance between the cutting torch and the pipe, the sensor will immediately trigger an alarm or automatically stop the cutting torch, effectively preventing safety accidents.
Increased Efficiency and Automation: Thanks to the precise measurement and quick response capabilities of the laser displacement sensor, the cutting torch can operate continuously and efficiently without frequent manual intervention, significantly improving production efficiency and the level of automation in cutting operations.
