Description

Technical Field

[0001] The utility model relates to the technical field of saw blades, in particular to a diamond saw blade with protective teeth. Background Art

[0002] Diamond saw blade is a cutting tool, widely used in the processing of hard and brittle materials such as concrete, refractory materials, stone, ceramics, etc. Diamond saw blade mainly consists of two parts: base and cutter head. The base is the main support part of the fixed cutter head.

[0003] Patent CN213860040U proposes a diamond saw blade with protective teeth, which is provided with two outer disk bodies, and the outer disk bodies are formed with outer protective teeth. The diamond cutter head is arranged between the outer protective teeth on the two outer disk bodies, and a double layer of protection is formed by the outer protective teeth on the two outer disk bodies, which greatly improves its protection performance. At the same time, the diamond cutter head and the outer protective teeth are detachably connected by bolts. When a diamond cutter head is damaged or an outer protective tooth on an outer disk body is damaged, it can be replaced separately, thereby reducing its replacement and maintenance costs.

[0004] The above scheme configures the cutter head and the tooth guard as a detachable structure, so as to facilitate the replacement of the damaged cutter head and tooth guard separately. However, in the scheme technology, the cutter head and the tooth guards on both sides are fixed by bolts. It takes a lot of time to install the tooth guards and the cutter head during the production of the saw blade, which also leads to a higher cost of the saw blade. Utility Model Content
