Description

Technical Field

[0001] The present invention relates to the field of laser cutting auxiliary technology, in particular to a laser cutting auxiliary device. Background Art

[0002] Laser cutting uses a focused high-power density laser beam to irradiate the workpiece, causing the irradiated material to quickly melt, vaporize, ablate or reach the ignition point, and at the same time uses a high-speed airflow coaxial with the beam to blow away the molten material, thereby achieving the cutting of the workpiece. Most laser cutting machines are controlled by CNC programs or made into cutting robots. Laser cutting, as a precision processing method, can cut almost all materials, including two-dimensional or three-dimensional cutting of thin metal plates. During the plate processing process, the workpiece is mostly fixed relative to the frame, and the laser head is moved along the length, width and height directions of the frame to complete the processing of the workpiece. After the paired plates are processed, the laser head can only disconnect the plates at the head section of the frame. While the processed plates are manually transported away, the feeding device returns to the head section of the frame to pick up the materials, so as to improve production efficiency.

[0003] At present, laser cutting machines are usually equipped with a cutting bed, which places the plate under the laser cutting head through a serrated matrix partition. However, during cutting, since the position and height of the matrix partition are fixed, the laser beam will penetrate the plate directly and damage the matrix partition, making its end uneven, requiring timely replacement and maintenance.
