Surface treatment method for hard alloy circular saw blade

Abstract

The invention belongs to the technical field of hardware tools, and particularly relates to a surface treatment method for a hard alloy circular saw blade. The surface treatment method comprises the following steps that 1, surface oil removal is conducted, specifically, the alloy circular saw blade is soaked in a degreasing agent and then transferred into clear water to be cleaned; 2, surface rustremoval is conducted, specifically, the alloy circular saw blade is soaked in a rust removal solution and then sequentially transferred into a neutralizer and clear water to be cleaned; 3, surface phosphating is conducted, specifically, the alloy circular saw blade is soaked in a phosphating solution and then transferred into clear water to be cleaned, and finally drying is conducted; and 4, surface painting is conducted, specifically, the alloy circular saw blade is fixed to a paint coating device, and the surface of the alloy circular saw blade is coated with anti-corrosion paint. When thesurface of the alloy circular saw blade is coated with the paint, the paint coating range can be accurately controlled, paint particles are prevented from being attached to saw tooth parts, the paintcoating the surface of the alloy circular saw blade can be uniformly dispersed, paint accumulation is avoided, and the surface flatness of the alloy circular saw blade is improved.

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 invention provides a method for treating the surface of a cemented carbide circular saw blade, aiming at the following problems in the prior art when the surface of the alloy circular saw blade is coated with paint: (1) the degree of paint coating cannot be accurately 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 the 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
