Abstract

The invention discloses a metal saw blade and a preparation method thereof, and relates to the technical field of saw blades. The metal saw blade comprises a saw blade body and saw teeth arranged on the saw blade body, wherein the saw teeth comprise first saw teeth arranged at the top of the saw blade body and second saw teeth arranged at the bottom of the saw blade body, and the first saw teeth and the second saw teeth are integrally formed with the saw blade body through the stamping technology. According to the metal saw blade and the preparation method thereof, the first saw teeth and second saw teeth arranged on the saw blade body are different in tooth distance, thus the first saw teeth and the second saw teeth can be replaced for use according to requirements, and the use performance is improved; a through groove and a hard alloy plate are arranged in the middle of the saw blade body, on one hand, materials can be saved, and on the other hand, the strength of the saw blade body can be improved; and an arranged installation mechanism is matched, thus the saw blade body can be conveniently connected with an external handle, the problem that deviation is prone to being generated in traditional threaded connection is solved, the operation is easy, and the use is convenient and fast.

Description

technical field [0001] The invention relates to the technical field of saw blades, in particular to a metal saw blade and a preparation method thereof. Background technique [0002] Saw blades are widely used in machinery manufacturing, wood processing, metallurgy, chemical industry, military industry and other industries. The saw blade is divided into frame saw blade and band saw blade. The frame saw blade is thin and long, and the symmetrical side of the saw back is made with several saw teeth. This kind of saw is installed on the frame saw machine tool for sawing workpieces; A long, circular saw with several teeth on one side of the saw back. [0003] Some of the existing metal saw blades adopt single-sided sawtooth design, which is inconvenient to use, and the strength of the metal saw blade is average, and it is easy to break due to excessive force. At the same time, when the metal saw blade is connected to the external handle, it is easy to fix it with a single bolt ...
