A laser cutting device for metal rails
By using a dynamic support structure and an active scraping dust collection system, the problems of easy burns to the support, easy clogging of the dust collection system, and difficulty in gripping and unstable stacking caused by thermal stress deformation in the laser cutting of metal guide rails have been solved. This has enabled high-precision cutting and stable stacking, improving the finished product quality and production efficiency of metal guide rails.

AI Technical Summary
Existing metal guide rail laser cutting equipment has several problems when processing long, strip-shaped precision guide rails, including easy burning of the bottom surface of the support structure, inability to adapt to gravity deformation, easy clogging of the dust collection system, and difficulty in gripping and unstable stacking due to thermal stress deformation after cutting.
The system employs a dynamic support structure that supports the guide rails with graphite pads and V-shaped support rollers. It combines a CCD camera to monitor thermal deformation and perform attitude compensation gripping, utilizes an active scraping dust collection system and flexible scraper to clean the filter screen, and uses a hydraulic cylinder to adjust the stacking height to maintain visual inspection accuracy.
It effectively prevents burns on the bottom surface of the guide rail, maintains cutting precision, ensures the stability of the dust collection system, achieves efficient gripping and stable stacking, and improves the surface quality of finished products and production efficiency.
