Problems solved by technology

[0003] Due to the high power density carried by the laser, when the laser is irradiated on the reflector and focus lens, even if the reflector and focus lens only absorb a very small part of the energy of the laser, it will still cause the reflector, focus lens and light tube fever
Especially when the laser head works for a long time, it will cause the temperature of the light tube to rise, causing damage to the focusing lens and reflector

Abstract

The invention provides a laser cutting laser head cooling device with high efficiency. The laser cutting laser head cooling device is characterized in that a water injecting wall 2 is arranged on a laser head outer wall 1; the shaft section of the water injecting wall 2 is circular; the lower end of the water injecting wall 2 is connected with the laser head outer wall 1 to form a bottom surface 3; multiple water spraying pipes 4 are upwards inclined on the bottom surface 3; the water spraying pipes 4 spray water at a constant speed; and a water sucking connection line 5 is arranged at the upper end of the water injecting wall 2, and is connected with a water sucking material 6. The water spraying pipes spray the water at the constant speed, so that the flowing water is contacted with the laser head outer wall for cooling; when the laser head is overheated, the water is quickly evaporated, so that the heat is sucked for cooling; when the water evaporation speed is slower, the redundant water is absorbed by the water sucking material through the water sucking connection line to realize automatic heat dissipation; and the flowing water accelerates the cooling speed, so that the cooling efficiency is high.

Description

technical field [0001] The invention relates to the field of laser cutting, in particular to a cooling device for a laser head for laser cutting. Background technique [0002] Laser cutting is to focus the 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. [0003] Due to the high power density carried by the laser, when the laser is irradiated on the reflector and focus lens, even if the reflector and focus lens only absorb a very small part of the energy of the laser, it will still cause the reflector, focus lens and light tube fever. Especially ...
