Description

Insertion pipe and welding mechanism for automatic welding production of structural pipe core material plate Technical Field The utility model relates to the field of building boards, mainly relates to processing production equipment for mass production and manufacturing of structural pipe core plates and metal pipe core plates, and in particular relates to a cannula and welding mechanism for automatic welding production of the structural pipe core plates. Background In the construction industry, hollow boards have been widely used because they significantly reduce the problem of material waste caused by solid boards. In recent years, sandwich panels, particularly structural tube sandwich panels, have become increasingly popular for their unique advantages. The plate realizes the aim of remarkably reducing the overall weight without sacrificing the structural strength by embedding the metal pipe between the double-layer metal plates and welding and forming. This feature not only optimizes the transportation and installation process, but also reduces the dead weight of the building. The introduction of the structural tube further enhances the rigidity and stability of the sheet material, and particularly, the structural tube can effectively disperse stress and prevent deformation when facing bending or torsion loads. In addition, the design of the structural pipe is flexible, and the position, the size and the number can be adjusted according to specific requirements, so that a customized solution is provided. The prefabricated sandwich plate material is convenient to assemble and connect on site, reduces on-site machining strength, and improves construction efficiency and quality consistency. The light-weight and excellent heat insulation performance of the building material is beneficial to energy conservation and emission reduction, reduces the operation cost and accords with the green building concept. Through innovative design, the structure pipe clamp core plate not only effectively solves the problem of material waste, but also comprehensively improves the performance of the building structure, and meets the comprehensive requirements of modern buildings on high efficiency, environmental protection, safety and economy. In the prior art, the welding between the metal tube and the metal plate has larger welding workload and uses brazing for welding, so that the problems of long time consumption, low efficiency, poor yield, poor welding quality and strength of brazing and the like exist in the high-temperature welding process. While the use of laser welding avoids these problems, the same efficiency problems are faced with the use of laser welding, typically with manual welding and equipment assistance, but the overall panel efficiency is still inadequate, and it is seen that the prior art lacks efficient laser welding equipment and techniques. Disclosure of Invention In order to overcome the defects and shortcomings in the background technology, the inventor improves and innovates the defects, and after multiple experiments and optimization and upgrading, a cannula and welding mechanism capable of efficiently and stably continuously and automatically generating and manufacturing a metal tube clamping core plate is developed. Specifically, the invention is realized as follows: The pipe inserting and welding mechanism for automatic welding production of the structural pipe core material plate is connected with pipe conveying equipment capable of continuously conveying metal pipe feeding, and is used for arranging the metal pipe between two metal plates, and comprises a pipe inserting device 61, a pipe inserting device and a welding device, wherein the pipe inserting device is connected with the pipe conveying equipment and comprises a pushing mechanism for pushing pipe feeding, and the pushing mechanism is used for pushing a single metal pipe 2 which enters in a blanking manner into a through hole 11 on the metal plate 1 and into a supporting slot 42 on the top surface of a base plate 4, so that the metal pipe 2 is positioned between opposite through holes 11 of the two metal plates 1; and 3, the insertion pipe device 61 and the laser welding device 62 form an insertion pipe and welding mechanism 6 which can form relative displacement with the metal plate, and are arranged into a plurality of sets which are respectively arranged on one side or two sides of the metal plate to be welded. Further, the pipe inserting device 61 pushes the metal pipe 2 corresponding to each supporting slot 42 from the pipe feeding device into the supporting slot 42, and the laser welding device 62 welds and fixes the metal pipe 2 in each supporting slot 42 and the metal plate 1.
