Key Structure and Motion Control
1. Machine Bed
The machine bed adopts a split-type structure consisting of the main bed and the unloading bed. It is fabricated from a welded steel plate and steel tube structure. After welding, the bed undergoes high-temperature annealing at 640°C and is held for 4.5 h. It is then slowly cooled in the furnace to 200–300°C before being removed for air cooling, effectively eliminating internal stress in the machine bed.
After stress relief treatment, the bed is subjected to rough machining followed by finish machining, which significantly improves the rigidity and stability of the machine and ensures long-term stable accuracy.
The machine features a side-hung structure and can be equipped with an automatic loading system, effectively improving loading efficiency while making unloading more convenient.
Rigidity: The machine bed adopts a welded steel plate and steel tube structure. The longitudinal and transverse bed sections are reinforced by multiple stiffeners and connecting plates, ensuring high overall rigidity.
Welding: Weld seams are evenly distributed on both sides and arranged in a symmetrical, staggered pattern to reduce welding deformation.
Annealing Report: Each machine bed has a corresponding annealing report traceable by serial number.
2. Loading System
The complete loading system consists of a conveyor chain and loading supports. The loader has a maximum load capacity of 1000 kg, with a maximum single-tube loading capacity of 260 kg. It enables automatic feeding of multiple batches of the same type of tube for cutting, offering a high level of automation and effectively reducing labor costs.
2.1 The standard machine can store up to 5 tubes for continuous feeding. Storage capacity of more than 5 tubes is available on request.
2.2 A servo-driven pneumatic flexible floating support system provides follow-up support during tube processing, effectively preventing tube whipping and avoiding accuracy deviation caused by tube movement.
3. Beam and X-/Z-Axis Assemblies
3.1 Beam
As the core supporting component of the X-axis motion system, the beam is annealed for stress relief to ensure the rigidity and stability of the moving components of the laser cutting head. During operation, travel is controlled by limit switches, while elastic buffer pads are installed at both ends as mechanical stops to ensure safe system operation.
3.2 Z-Axis Assembly
The Z-axis assembly is mainly used for the vertical movement of the laser cutting head. Its up-and-down motion is controlled by the CNC system through a servo motor, which drives a linear module to move the Z-axis slide repeatedly in the vertical direction. Proximity switches are installed at both the upper and lower ends for travel control, ensuring safe and reliable motion.
4. Laser Cutting Head and Follow-Up System
4.1 The sealing performance of the protective area is monitored in real time, effectively extending the service life of the protective lens and ensuring stable production.
4.2 The laser cutting head features an anti-collision design, which effectively reduces the likelihood of return-to-factory repairs. Components can be replaced on site by the customer without requiring after-sales service personnel, helping lower maintenance costs.
4.3 A dust-proof cover is added to the optical lens area to improve the sealing level of the core chamber and further extend the service life of the core optical lenses.
4.4 Equipped with a high-precision capacitive automatic tracking system, the unit achieves stable Z-axis floating under system control, effectively preventing height errors caused by thermal deformation or uneven tube surfaces during tube cutting.
