Description

technical field [0001] The invention relates to the field of laser cutting equipment, in particular to a PLC system-based integrated optical fiber laser cutting machine for plates and tubes. Background technique [0002] Fiber laser cutting uses a focused high-energy-density laser beam to irradiate the workpiece. Under the premise of the laser energy density exceeding the laser threshold, the energy of the laser beam and the chemical reaction heat generated by the active gas-assisted cutting process act on the material. This causes the temperature of the laser action point to rise suddenly. After reaching the melting and boiling point, the material begins to melt or vaporize to form holes. With the relative movement of the beam and the workpiece, a slit is finally formed on the material. Laser cutting has the following characteristics. First, laser cutting has no contact, no tool wear, narrow kerf, small heat-affected zone, small incision surface roughness, good incision par...

AI Technical Summary

Problems solved by technology

[0003] The current fiber laser cutting machine has gradually replaced the gas laser cutting machine, but in the existing fiber laser cutting machine, it is necessary to manually adjust the laser cutting focus to adapt to plates of different materials and thicknesses, resulting in low adjustment accuracy and low efficiency. Moreover, the existing fiber laser cutting machines can only process plates or pipes, and cannot process plates and pipes at the same time
