Description
Technical Field
The invention relates to the technical field of laser cutting machines, in particular to a laser cutting machine with a plate fixing device.
Background
The laser cutting is to irradiate the material to be cut by using high-power-density laser beams, so that the material is heated to a vaporization temperature quickly and is evaporated to form holes, and the holes continuously form slits with narrow width (such as about 0.1 mm) along with the movement of the laser beams to the material, so as to finish the cutting of the material.
Due to the cutting condition requirements of the laser, the laser cutting device is mainly used for cutting metal materials, and is particularly suitable for cutting metal sheets. But can discover in the time of actual cutting process, the metal sheet that treats the cutting often can be because reasons such as transportation, transport take place warpage scheduling problem easily, and especially corner region, and then leads to the metal sheet on the lathe to be unable level and smooth putting, and this can influence laser cutting's cutting precision and the finished product's of cutting yields greatly.
Disclosure of Invention
The invention provides a laser cutting machine with a plate fixing device, aiming at the defects of the existing laser cutting machine in cutting a metal sheet, and solving the problems that the edge and corner regions of the metal sheet are warped, the cutting precision of laser cutting is affected and the yield of cut finished products is high. The specific technical scheme is as follows:
a laser cutting machine with a plate fixing device is provided with:
the movable lower pressing device can be detachably fixed on the corners of the metal thin plate, and is in the shape of a wing;
a high-velocity gas flow region formed corresponding to the depressor, the high-velocity gas flow region forming a pressure difference of an upper portion and a lower portion of the depressor disposed inside thereof.
Furthermore, the lower pressure device is provided with a bottom surface and a top surface, wherein the bottom surface is an arc surface, and the top surface is a plane.
Further, a clamping area is formed between the top surface, the elastic clamp and the top surface.
Further, the high-speed airflow region is generated by a high-speed fan.
