Description

Technical Field

[0001] The invention relates to the field of saw blades, and in particular to a low-cost and high-hardness saw blade head capable of effectively extending the service life. Background Art

[0002] Saw blades are a general term for thin circular tools used to cut solid materials. According to different applications, saw blades can be divided into: milling saw blades, machine saw blades, manual saw blades, metal-specific saw blades (aluminum saw blades, copper saw blades, stainless steel saw blades, etc.), pipe cutting circular saw blades, wood saw blades, stone saw blades, acrylic saw blades, etc. According to different material classifications, they can be divided into: high-speed steel saw blades (HSS saw blades), welded alloy saw blades, toothed alloy saw blades, diamond saw blades, etc.

[0003] Among them, carbide circular saw blades can still play their excellent performance in harsh working conditions with their advantages of high speed, good cutting quality and precision, and high production efficiency. However, the shortcomings in the performance of carbide saw blades have greatly restricted the performance of higher efficiency and customer cost requirements. The specific defects are as follows: First, the influence of high-temperature welding. The alloy blade block and the saw blade body are welded under high temperature. Repeated heating will cause decarburization in the heating area of ​​the blade body itself, and the structure will change, which is easy to cause crack defects during use. Second, repeated high-temperature heating will have an adverse effect on the rigidity, hardness, strength and stress of the blade body. Third, the solid-welded alloy blade block can only complete cutting with one cutting edge, and it cannot be used again after being damaged, which greatly increases the use cost of the alloy. Fourth, due to the influence of heat, the mechanical properties and cutting performance of the alloy blade block coating will be seriously reduced during high-temperature welding of the carbide blade block coated with CVD and PVD, and it cannot be widely used.

[0004] In order to solve the above problems, the applicant has developed a combined carbide circular saw blade with patent number CN202110359235.X, which aims to reduce the use cost of the alloy cutter head, improve production efficiency, improve cutting performance, and bring about economic benefits. It includes a saw blade body and a cutter head, and tooth-shaped protrusions are evenly arranged on the outer edge of the saw blade body. The upper part of each tooth-shaped protrusion is provided with a cutter head seat for placing the cutter head. The side of the cutter head seat is a side end wall. The side end wall and the cutter head are in contact in the thickness direction of the saw blade body and are arranged side by side. The side end wall and the cutter head are fixed together by screws, and the cutter head is evenly distributed with 2 to 10 identical cutting edges.

[0005] Although the above-mentioned combined carbide circular saw blade can effectively extend the service life, the use of hard materials for the entire cutter head still cannot effectively reduce the cost of use. Therefore, there is an urgent need for a low-cost and high-hardness saw blade cutter head that can effectively extend the service life and improve the above-mentioned problem. Summary of the invention

[0006] The purpose of the present invention is to provide a low-cost and high-hardness saw blade head that can effectively extend the service life, so as to solve the problems existing in the above-mentioned prior art.
