Durable saw blade

Abstract

The invention discloses a durable saw blade. The durable saw blade is characterized in that the durable saw blade comprises a saw blade body; saw teeth are continuously arranged on the two sides of the saw blade body in the axis direction, each saw tooth is formed by continuously arranging a left tooth, a middle tooth, a right tooth and a U-shaped groove in the axis direction of the saw blade body; the two ends of the saw blade body are each provided with a handle; and the surface of the saw blade body and the surfaces of the saw teeth on the two sides are evenly coated with ceramic coatings. The durable saw blade has the beneficial effects that the TiC-TiB2 ceramic coatings are arranged on the surface layer, so that the saw blade has the advantages of being high in wear resistance and hardness; the durable saw blade is easy to manufacture, convenient to operate and high in work efficiency; by means of the arrangement of the U-shaped grooves, chips generated in the use process of the saw bladed can be cleared away in time, and heat generated by friction can be dissipated out in time; and the work efficiency is high, and the service life is long. Rubber layers are arranged on the handles, and therefore the hurt of steel pieces to the hands of workers is effectively relieved, and unnecessary accidents are avoided.

Description

technical field [0001] The invention belongs to the field of electric tool accessories, and in particular relates to a durable saw blade. Background technique [0002] In the machinery manufacturing industry, the saw blade is a very widely used processing tool. Saw blades must withstand high pressure, high temperature and friction during processing, so the materials used to manufacture saw blades must meet the following requirements: (1) high hardness; (2) high strength and toughness; (3) good wear resistance and heat resistance ; (4) good thermal conductivity; (5) good manufacturability. High-speed steel has the advantages of high strength, high toughness and good manufacturability, and is one of the main materials for manufacturing complex saw blades. [0003] The entire saw blade body of the traditional saw blade is made of high-speed steel. Such a saw blade has the following disadvantages: first, because the high-speed steel is more expensive than alloy steel, the cost...

Problems solved by technology

[0003] The entire saw blade body of the traditional saw blade is made of high-speed steel. Such a saw blade has the following disadvantages: first, because the high-speed steel is more expensive than alloy steel, the cost of the traditional saw blade is relatively high, and it is difficult to win the favor of the market; in addition, although High-speed steel has strong strength, but with the extensive use of difficult-to-machine materials such as high-strength steel, ceramic materials, and composite materials in the fields of aerospace, ships, and automobiles, the existing high-speed hacksaw blades will still appear when they are used. Severe wear and short service life, etc., so the hardness and wear resistance of the saw blade need to be further improved
