Description

Technical Field

[0001] The utility model relates to the technical field of optical fiber laser cutting, in particular to an air pressure control device for optical fiber laser cutting. Background Art

[0002] Fiber laser cutting refers to a cutting technology that uses high-power lasers generated by fiber lasers to cut materials. During fiber laser cutting, auxiliary gases such as carbon dioxide and nitrogen need to be sprayed on the cutting area. The auxiliary gases can not only remove cutting impurities at the cutting area, but also fully protect the fiber laser cutting equipment.

[0003] The existing air pressure control device for fiber laser cutting includes the following structure: Publication No. CN210848836U discloses an air pressure control device for fiber laser cutting, including a gas source, a gas pipeline, a proportional valve, a controller, a gas injector, a gas nozzle, an air pressure sensor, and a wire; the gas source is connected to the air inlet of the proportional valve through a gas pipeline; the air outlet of the proportional valve is connected to the gas injector through a gas pipeline, and the gas injector is installed on the side of the laser cutter; the above structure can conveniently adjust the injection pressure of the auxiliary gas and improve the cutting accuracy and quality.

[0004] The above prior art often has the following problems when used:

[0005] 1. When cutting thicker materials, the laser cutter will produce a deeper cutting groove. At this time, the auxiliary gas with the same pressure cannot completely remove the melted or evaporated material in the cutting groove, which affects the cutting quality of the material;

[0006] 2. In addition, the injection angle of the auxiliary gas during optical fiber cutting is fixed. After the cutting is completed, a small amount of unevenly distributed cutting material may still remain at the cutting position. The auxiliary gas injected at a fixed position is not convenient for removing the remaining cutting material, which increases the subsequent cleaning work cost. Utility Model Content

DETAILED DESCRIPTION

[0024] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0025] like Figure 1-Figure 3 As shown, the embodiment of the utility model proposes an air pressure control device for fiber laser cutting, including a cutting platform 1, an air jet adjustment component and a cutting component: a support frame 2 is fixedly connected to the cutting platform 1, a fixed pad 17 is fixedly connected to the cutting platform 1, and an anti-slip pattern is arranged on the outer surface of the fixed pad 17; the air jet adjustment component includes an annular plate 3 rotatably connected to the top of the support frame 2 through an annular bearing, an adapter bracket 4 is fixedly connected to the outer wall of the annular plate 3, an air pump 5 is fixedly connected to the adapter bracket 4, an air tank 15 is fixedly connected to the top of the support frame 2, the air tank 15 is connected to the air pump 5 through a connecting pipe 16, the connecting pipe 16 adopts a telescopic corrugated hose, and an air jet nozzle 6 is arranged at the lower end of the air pump 5;

[0026] By driving the air pump 5 to rotate, the air pump 5 and the air nozzle 6 rotate with the laser cutting machine 8 as the center, so that the air injection angle can be quickly adjusted, and the residual cutting material unevenly distributed at the cutting site can be cleared through the air nozzle 6 at the lower end of the air pump 5, which is beneficial to reduce the subsequent cleaning work cost.

[0027] like Figure 1-Figure 3 As shown, a rotating driving component is provided on the top of the supporting frame 2, and the rotating driving component includes a rotating shaft rotatably connected to the top of the supporting frame 2, a transmission gear 12 is fixedly connected to the rotating shaft, an inner gear ring 13 is fixedly connected to the inner side of the annular plate 3, and the inner gear ring 13 and the transmission gear 12 are meshed with each other, and a rotating motor 14 is installed on the top of the supporting frame 2, and the upper end of the rotating shaft passes through the top of the supporting frame 2 and is fixedly connected to the output end of the rotating motor 14;
