Description

Technical Field

[0001] The utility model relates to the technical field of steel saw blades, in particular to a high-speed steel saw blade with a cooling structure. Background Art

[0002] High-speed steel is a special alloy steel, not a specific element or compound. It is a type of high-performance tool steel, mainly used to manufacture cutting tools such as knives, blades, drills, milling cutters, etc., especially suitable for high-speed cutting and high-temperature working environments. The main components of high-speed steel include carbon (C), tungsten (W), molybdenum (Mo), chromium (Cr), cobalt (Co), etc. The combination of these elements gives high-speed steel excellent hardness, wear resistance, high temperature resistance and cutting performance. High-speed steel is widely manufactured and used, and it occupies an important position in the cutting tool industry because it can maintain stable performance under high-speed cutting and high-temperature conditions.

[0003] After searching, the Chinese patent document announcement number: CN213257490U discloses a high-speed steel saw blade with a cooling structure, including a saw blade body, a cooling shield and a water injection nozzle, the saw blade body is arranged on the outside of the saw blade body; the water injection nozzle is threadedly connected to the top of the saw blade body; the water injection nozzle is connected to a cutting fluid high-pressure delivery pump through a hose. When in use, the saw blade body cuts an object through the alloy cutter head on the saw teeth, and at the same time, the cutting fluid high-pressure delivery pump uses a hose to transport the cutting coolant to the cooling shield, and then cools the saw blade body through the water nozzles evenly distributed in the cooling shield. When cooling, the cooling area is large and the temperature drops quickly, which can extend the working time of the saw blade body and improve its service life.

[0004] Although the above patent mentions in the beneficial effects that "when the high-speed steel saw blade with a cooling structure is used, the saw blade body cuts the object through the alloy cutter head on the saw teeth, and at the same time, the cutting fluid high-pressure delivery pump uses a hose to deliver the cutting coolant to the cooling shield, and then the saw blade body is cooled by the water nozzles evenly distributed in the cooling shield. During cooling, the cooling area is large, the temperature drops quickly, and the working time of the saw blade body can be extended, and its service life can be increased", although the saw blade body 1 is cooled by the water nozzles 5 evenly distributed in the cooling shield 2, and during cooling, the cooling area is large, the temperature drops quickly, and the working time of the saw blade body 1 can be extended, and its service life can be increased, but after the coolant and water are sprayed out, part of the coolant or water fails to contact the saw blade and fails to have a cooling effect, which leads to a reduction in the cooling effect and a waste of resources. Therefore, in view of the above deficiencies, a high-speed steel saw blade with a cooling structure is proposed. Utility Model Content

[0023] Reference Figure 2-3 , the adjacent sides of the two arc-shaped plates 6 are respectively fixedly connected to the front and rear sides of the rotating disk 3. The arc-shaped plates 6 are designed here to transport coolant and water to the interior of the rotating disk 3. Through holes are provided inside the multiple connecting rods 8.
