Description

Technical Field

[0001] This utility model belongs to the field of sheet metal processing technology, and more specifically, it relates to a CNC shaping and cutting saw and a sheet metal. Background Technology

[0002] Sandwich panels, widely used composite building materials in the construction industry, are typically composed of a metal outer panel and a lightweight core material, offering advantages such as light weight and excellent thermal insulation. In traditional sandwich panel production, the core material is often made of polystyrene (EPS) or polyurethane (PU) foamed using molds. However, this process suffers from high mold costs and poor adaptability to irregularly shaped structures. With the increasing demand for diverse building designs, higher precision is required in the cutting and splicing of irregularly shaped core materials.

[0003] In existing technologies, core material cutting mostly uses ordinary wire saw equipment, and curve processing is completed by manually adjusting the cutting path. This type of equipment has the following drawbacks: 1. The cutting system lacks multi-axis linkage control, making it difficult to achieve continuous high-precision cutting of complex curves (such as S-shaped wavy lines); 2. The cutting wire tension adjustment mechanism uses mechanical spring control, which is prone to tension fluctuations during high-speed cutting, resulting in serrated burrs on the cut surface; 3. The material conveying platform mostly uses belt drive, resulting in low repeatability (typically > ±1mm), affecting the edge fit when splicing multiple core materials.

[0004] In terms of panel structure, existing sandwich panels mostly use rectangular flat plates directly spliced ​​together, with the splicing surfaces in straight contact. This structure has obvious defects: First, the contact area of ​​the straight splice is limited, which easily leads to stress concentration at the splice when subjected to vertical loads, resulting in delamination of the core material; Second, the continuous seams formed by the straight splice become heat conduction channels, significantly reducing the overall thermal insulation performance of the panel.

[0005] Therefore, this utility model provides a CNC shaping and cutting saw and a sheet metal. Utility Model Content
