Description

Technical Field

[0001] The present invention relates to the field of laser cutting technology, and in particular to a laser cutting support structure with intelligent switching of cutting points. Background Art

[0002] In today's rapidly developing industrial field, laser cutting technology has become the preferred processing method for many manufacturing companies due to its excellent precision, efficient cutting speed and wide applicability. The performance of the laser cutting support structure as an important auxiliary equipment in the laser cutting process directly affects the cutting quality and production efficiency. The traditional laser cutting support structure has played a certain role in the past industrial production, but with the continuous improvement of industrial demand and the continuous advancement of technology, its limitations have become increasingly prominent. Most of the widely used support structures currently adopt a fixed support method. When facing workpieces of different shapes, sizes and materials, although it can provide a certain degree of stability for the workpiece, it ensures that the workpiece will not be damaged during the cutting process. Displacement or shaking, however, this fixed support method has a serious disadvantage, that is, the workpiece in the support position cannot be cut during the cutting process. This disadvantage has brought many problems in actual production. First, for some workpieces with complex shapes, such as workpieces with curved surfaces, concave angles or irregular contours, traditional support structures often hinder the laser beam from reaching certain key parts, resulting in these parts being unable to be completely cut. This not only affects the overall quality of the workpiece, but also may make the workpiece after cutting unable to meet the design requirements and require additional secondary processing. Secondary processing not only increases production time and cost, but also reduces production efficiency, affecting the economic benefits of the enterprise. Secondly, in some application fields with extremely high precision requirements , such as aerospace, precision instrument manufacturing, etc., even if the tiny support position is not cut cleanly, it may have a significant impact on the performance and reliability of the entire product. For example, in the manufacture of aviation parts, any residual support material may affect the aerodynamic performance or structural strength of the parts, thereby endangering the safety of the aircraft. In addition, the limitations of traditional support structures also limit the application of laser cutting technology in the processing of some special materials. For some high-hardness, high-brittleness or heat-sensitive materials, accurate cutting is essential. However, since the support position cannot be cut, stress concentration, cracks or deformation may occur on these materials, seriously affecting the performance and service life of the materials. Moreover, from the production process From the perspective of the process, the shortcomings of traditional support structures have also brought certain difficulties to production management. In order to avoid the influence of support position on cutting, production personnel need to perform complex workpiece positioning and support structure adjustments before cutting, which not only increases the complexity of operation, but also is prone to human errors. Moreover, in the process of processing different workpieces, it may be necessary to frequently replace support structures or make cumbersome adjustments, further reducing production efficiency. The existing support structure for laser cutting cannot cut the workpiece at the support position during the cutting process. This shortcoming has become an important factor restricting the further development and application of laser cutting technology. In order to solve this problem, there is an urgent need for a new type of laser cutting support structure with intelligent switching of cutting points. Summary of the invention
