Problems solved by technology

There are defects such as matrix deformation and surface scratches in the processing and production process of the existing cemented carbide saw blades, which lead to large axial runout of the saw blade during use and a large friction coefficient with the cutting material, which not only affects the cutting accuracy but also shortens the cutting time. The service life of the saw blade

Embodiment 1

[0023] A method for processing cemented carbide saw blades, which includes the following steps: leveling the substrate of the cemented carbide saw blade → rolling teeth → welding the cutter head → sandblasting → grinding teeth → polishing → anti-rust treatment → storage of finished products; The step of welding the cutter head is interdental welding; the abrasive belt in the polishing step is 180 mesh, and the relative speed between the cemented carbide saw blade substrate and the abrasive belt is 4000r / min. The corundum in the blasting step is 40 mesh, and the blasting time is 10s. The antirust treatment steps include cleaning, oil immersion and drying of the carbide saw blade. The immersion oil used in the oil immersion step includes a varnish and a diluent in a mass ratio of 2:3. The varnish agent includes alkyd resin and butanol, and the mass ratio is 2:1. The diluent is xylene. The drying temperature is 80° C., and the drying time is 30 minutes.

Abstract

The invention relates to a machining method for a hard alloy saw web.The machining method includes the following steps of leveling of a base body of the hard alloy saw web, gear rolling, tool bit welding, sand blasting, gear grinding, polishing, antirust treatment and finished product storage.Gear spacing welding is adopted for the tool bit welding step.An abrasive belt in the polishing step is 180 mesh or 240 mesh, and the relative speed of the base body of the hard alloy saw web and the abrasive belt is 4,000-4,500 r / min.Heating deformation of the base body in the machining process can be effectively controlled, the surface smooth degree is high, and the anti-corrosion effect is good.

Description

technical field [0001] The invention relates to a processing method of a saw blade, in particular to a processing method of a cemented carbide saw blade. Background technique [0002] Tungsten carbide saw blades, as cemented carbide cutting tools, are specially made for cutting and grooving metal materials. They are the most commonly used cutting tools for wood product processing. The quality of cemented carbide saw blades is closely related to the quality of processed products. [0003] A common cemented carbide saw blade includes a substrate and several cutter heads welded on the outer edge of the substrate. The flatness and surface smoothness of the substrate and the sharpness of the cutter head determine the quality of the carbide saw blade. There are defects such as matrix deformation and surface scratches in the processing and production process of the existing cemented carbide saw blades, which lead to large axial runout of the saw blade during use and a large fricti...
