Description

Technical Field

[0001] The present invention relates to the technical field of metal plate cutting, and more particularly to a metal plate cutting processing device. Background Art

[0002] With the development of society, people are using more and more plates. Metal, as a hard material, is often made into plates for use. Due to the hard texture of metal plates, large plates are often cut by cutting machines before cutting. Therefore, cutting machines for metal plate processing have gradually developed. With the emergence of high-power lasers, laser cutting applications are becoming more and more widespread. Laser cutting uses invisible light instead of traditional mechanical knives, and has the advantages of small deformation and good repeatability.

[0003] During laser cutting, since the temperature at the cutting position is relatively high, a cooling device is often required. For example, a Chinese invention patent (CN114043097A) discloses a laser cutting device for plate processing. The cutting device cools the laser cutting position by arranging an air cooler in a side support seat. However, this cooling method has a poor effect.

[0004] In the prior art, some water cooling solutions have been proposed, among which the Chinese utility model patent (CN213888651U) discloses a heat dissipation structure for a laser cutting machine, which can cool the entire bottom surface of the metal plate at the same time by setting a water spray pipe and an atomization port under the plate, and connecting the water pipe to a condenser or other refrigeration device. However, this structure will spray the cooling water on the plate indiscriminately, which is a great waste of water resources. At the same time, for the cooling device, its cooling load is large and the energy consumption is high.

[0005] Therefore, based on the above problems, the applicant invented a metal sheet cutting device. Summary of the invention
