Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of laser cutting, and particularly relates to a double-Y-axis 360-degree surrounding laser cutting machine. BACKGROUND

[0002] The laser cutting technology is to use a high-power laser beam to locally heat a material and cut the material through the high-temperature melting or evaporation effect of the laser beam. Since the technology was developed in the late 1960s, it has become one of the most advanced cutting technologies in modern manufacturing. Laser cutting has the advantages of high cutting precision, small heat-affected zone, and strong adaptability. In particular, in high-difficulty and high-precision cutting tasks, laser cutting shows incomparable advantages. The double-Y-axis 360-degree surrounding laser cutting machine introduces a rotating platform or a multi-degree-of-freedom motion control system, so that the laser cutting head can cut around the workpiece in all directions. Through this design, the laser cutting machine can cut the object at multiple angles without changing the position of the workpiece. When performing 360-degree surrounding cutting, the running speed of the laser head is required to be high. Especially when cutting small square tubes or holes on four sides or more, the laser head needs to be lifted for a long time for positioning and cutting. When cutting a complex workpiece, the laser cutting head needs to be lifted more times, and the long travel distance and slow speed will greatly affect the work time. Therefore, a double-Y-axis laser cutting machine is designed to reduce the running time of the laser head when it is lifted and lowered multiple times, and to improve the work efficiency. Moreover, when processing some irregular workpieces or large and heavy workpieces, it is time-consuming and laborious to unload, turn over, and then load and cut. The 360-degree surrounding cutting method can realize feeding and cutting at the same time, and can avoid such problems. SUMMARY
