A kind of surface treatment method of cemented carbide circular saw blade

Abstract

The invention belongs to the technical field of hardware tools, and specifically relates to a surface treatment method for a cemented carbide circular saw blade, comprising the following steps: Step 1, surface degreasing: soak the alloy circular saw blade in a degreasing agent, and then transfer it to clear water for cleaning ;Step 2, surface rust removal: soak the alloy circular saw blade in the rust removal solution, and then turn it into a neutralizer and clean water for cleaning; step 3, surface phosphating: soak the alloy circular saw blade in the phosphating solution , then wash in clean water, and finally dry; step 4, surface painting: fix the alloy circular saw blade on the paint coating device, and coat the surface with anti-corrosion paint. When the present invention is used to coat the surface of the alloy circular saw blade with paint, the precise control of the paint coating range can be realized, the paint particles can be avoided from adhering to the sawtooth part, and the paint coated on the surface of the alloy circular saw blade can be protected. Evenly disperse, avoid the accumulation of paint, and improve the surface smoothness of alloy saw blades.

Description

technical field [0001] The invention belongs to the technical field of hard alloy material processing, and in particular relates to a surface treatment method of a hard alloy circular saw blade. Background technique [0002] Tungsten carbide saw blades are the most commonly used cutting tools for wood products processing. Tungsten carbide saw blades include many parameters such as the type of alloy cutter head material, the material of the substrate, diameter, number of teeth, thickness, tooth shape, angle, aperture, etc. These parameters It determines the processing ability and cutting performance of the alloy saw blade. Due to the high-speed friction between the alloy saw blade and the body to be cut during work, a large amount of heat is generated, which will also cause a certain loss to the alloy saw blade itself. In order to improve the wear resistance of the alloy saw blade and prolong the service life of the alloy saw blade, after the alloy saw blade is manufactured,...

Problems solved by technology

[0005] The present invention provides a method for surface treatment of cemented carbide circular saw blades, aiming at the following problems existing in the prior art when coating the surface of alloy circular saw blades with paint: (1) The degree of paint coating cannot be precisely controlled range, paint particles will adhere to the sawtooth parts that do not need to be coated, on the one hand, it will cause waste of paint, and on the other hand, it will affect the working performance of the sawtooth parts; (2) The thickness of paint coating is uneven, and it is easy to form paint The accumulation of the alloy saw blade affects the flatness of the surface of the alloy saw blade, which in turn affects the forming quality of the cutting edge on the body during cutting
