Problems solved by technology

It can be seen from the market (1): Traditional carbide saw blades have obvious tooth-like structures. Under high-speed use, especially portable electric tools, there is a major safety risk of tooth-like structure breaking; (2) there is a hard alloy saw blade High-quality alloy particle saw blade, although it has no tooth structure, but it uses particle alloy, the shape and specification are not uniform, and the arrangement is disorderly, which will lead to reduced cutting efficiency and poor cutting quality, and more burrs

Abstract

The invention discloses a hard alloy welding circular saw blade without a tooth-shaped structure. The hard alloy welding circular saw blade comprises a saw blade base body, the saw blade is in a circular shape without the toothless-shaped structure and the outer edge is smooth, a plurality of particle tool bits are orderly arranged along the outer circumference of the saw blade base body, and eachparticle tool bit can be subjected to edge grinding machining according to requirements. According to the hard alloy welding circular saw blade without the tooth-shaped structure, how to adjust the local structure of the saw blade can be further elaborated according to the basic principle under the conditions of welding with brazing filler metal and welding without brazing filler metal; the saw blade has a wide market prospect in portable electric tools and battery electric tools; and the safety, the accuracy and the multifunctionality of the saw blade are greatly improved.

Description

technical field [0001] The invention relates to the technical field of cutting tools, in particular to a cemented carbide welded circular saw blade with no tooth structure. Background technique [0002] At present, alloy circular saw blades are widely used as accessories of power tools in modern manufacturing and construction industries. It can be seen from the market that (1): Traditional carbide saw blades have obvious tooth-like structures. Under high-speed use, especially portable electric tools, there is a major safety risk of tooth-like structure breaking; (2) there is an existing hard alloy saw blade. High-quality alloy granulated saw blades have no tooth structure, but they are made of granulated alloys, with inconsistent shapes and specifications, and disorderly arrangement, which will lead to reduced cutting efficiency, poor cutting quality, and more burrs. [0003] In order to further improve the safety of electric tools, improve cutting efficiency, prolong cutti...
