Description

An automatic blanking device for a laser cutting machine

technical field

The utility model relates to the technical field of laser cutting machines, in particular to an automatic blanking device of the laser cutting machine.

Background technique

As we all know, the laser cutting machine focuses the high-energy laser emitted from the laser into a high-power-density laser beam through the optical path system. The laser beam irradiates the surface of the workpiece to make the workpiece reach the melting point or boiling point, and at the same time, the high-pressure gas coaxial with the beam blows away the molten or vaporized metal. With the movement of the relative position of the beam and the workpiece, the material will eventually form a slit, so as to achieve the purpose of cutting.

When the existing laser cutting machine cuts the profile, the laser cutting head cuts the profile under the control of the program, and the cut profile falls freely on the frame, and the cut profile will hit the frame when it falls. It is very easy to be deformed and damaged on the bottom surface, and when there are too many profiles falling near the frame, it is necessary to manually transport these cut pieces to the pallet. When the cut pieces are long and heavy, multiple workers are required to cooperate with the handling , because the space at the rack is relatively narrow, it is not convenient for manual handling, and it is easy for workers to hit other colleagues when carrying it, which is not safe. At the same time, the dropped cutting parts are very messy and unsightly. Sorting is very inconvenient and consumes too much manpower. Therefore, we propose an automatic blanking device for a laser cutting machine to solve the above problems.
