Description

Full-automatic laser pipe cutting machine with saw cutting function Technical Field The application relates to the technical field of laser cutting, in particular to a full-automatic laser pipe cutting machine with a sawing function. Background Along with the rapid development of the intelligent manufacturing and pipe processing industry, the laser pipe cutting machine becomes main stream equipment in the field of pipe cutting by virtue of the advantages of high cutting precision, small heat affected zone, smooth cutting section and the like. The laser pipe cutting machine in the prior art has the core working principle that a laser beam with high energy density is used as a cutting heat source to irradiate the surface of the pipe, so that the material in the irradiated area of the pipe is quickly melted and vaporized, and meanwhile, the melted material is blown away from a cutting surface by virtue of auxiliary gas, so that the pipe is cut and processed. The conventional laser pipe cutting machine is generally provided with core components such as a laser generator, a cutting head, a pipe clamping and positioning mechanism, a numerical control system and the like, can realize efficient cutting of conventional single-layer structure pipes such as round pipes, square pipes and rectangular pipes, and meets the requirements of most conventional pipe processing scenes. However, in actual industrial production, in addition to the conventional single-layer structural pipes, the application of multi-layer composite structural sections is increasingly widespread, and the multi-layer structural sections are usually formed by laminating and compositing materials with different materials or different properties, for example, composite pipes with an inner layer of corrosion-resistant alloy and an outer layer of high-strength carbon steel, or special-shaped sections with a hollow sandwich structure play an irreplaceable role in some scenes with special requirements on material properties. However, when the existing laser pipe cutting machine is used for cutting and processing the multi-layer structural section, obvious technical defects are exposed, and the actual processing requirements are difficult to meet. On the one hand, the action mechanism of laser cutting depends on the thermal action of laser beams on materials, and different material layers of the multi-layer structural profile often have different thermophysical properties, such as melting point, thermal conductivity, absorptivity and the like, which are greatly different. When laser beam acts on the outer layer of the profile, the outer layer material may reach melting or vaporization temperature, but the inner layer material cannot be effectively melted due to low heat conduction efficiency or higher self melting point, and if the laser power is increased or the irradiation time is prolonged, the outer layer material is extremely easy to be excessively ablated, so that the quality of a cut section is reduced, and even the problems of material deformation, performance degradation and the like occur. On the other hand, for the multilayer section bar with part of the inner layer structure being complicated or the thickness being larger, the penetrating capacity of the laser beam is obviously limited, the inner layer material can not be effectively reached and the cutting can not be completed, so that the traditional laser pipe cutting machine can not realize the complete cutting of the multilayer section bar, and only the outer layer of the traditional laser pipe cutting machine can be simply grooved or cut off, so that the requirement of the whole cutting of the multilayer section bar in the industrial production can not be met. In summary, when the existing laser pipe cutting machine faces the cutting requirement of the multi-layer structural section, the existing laser pipe cutting machine has the technical defects of incomplete cutting, poor section quality, low processing efficiency, high cost and the like, and is difficult to adapt to the actual requirement of processing the multi-layer structural section in the current industrial production. Therefore, developing a device capable of combining conventional pipe laser cutting and multi-layer structural profile complete cutting becomes a technical problem to be solved in the field.
