Description

Technical Field

[0001] The utility model relates to the technical field of laser cutting, in particular to a sheet metal laser cutting machine. Background Art

[0002] Sheet metal laser cutting machine is an advanced cutting process, mainly used for sheet metal processing. In traditional sheet metal processing, mechanical tools are usually used for cutting. However, with the development of science and technology, laser cutting technology has gradually replaced traditional mechanical cutting methods. The laser processing technology used by the laser cutting machine is a composite advanced manufacturing technology that integrates light, machinery, electricity, material processing and detection. This technology uses a high-power beam to irradiate the surface of the sheet metal, so that the irradiated metal reaches the melting point and melts instantly. At the same time, the coaxial high-pressure gas blows the molten and vaporized metal away from the sheet metal, thereby achieving metal cutting. Compared with traditional mechanical cutting, laser cutting has many advantages. First, laser cutting has high precision and high speed, and can quickly and accurately cut sheet metal parts of various shapes. Secondly, laser cutting is not limited by the cutting pattern, can automatically layout and save materials. In addition, the incision of laser cutting is smooth and the processing cost is low, which can improve production efficiency and reduce costs.

[0003] However, when the laser cutting machine processes metal workpieces, the metal workpieces need to be clamped to ensure the processing accuracy. Currently, most workpieces are placed flat on the laser cutting machine. The clamping equipment is bulky, inconvenient to operate, and the efficiency is very low. For this reason, we propose a sheet metal laser cutting machine. Utility Model Content
