Polymeric diamond saw blade and manufacturing process thereof

Abstract

The invention discloses a polymeric diamond saw blade and a manufacturing process thereof. According to the polymeric diamond saw blade and the manufacturing process thereof, silver solder wires and single-layer silver solder plates are adopted as main solders for welding a saw blade body and sawteeth, polymeric diamond tool bits are arranged on the sawteeth, the sawteeth are welded on an L-shaped toothholder of the saw blade body, and a PVD coating further coats the rear cutter surfaces of the sawteeth. The polymeric diamond saw blade is long in service life, is particular suitable for saw cutting of materials including phosphor-copper alloy, silver-copper alloy and conventional ceramic through a metal cold saw, and has relatively high cutting precision; through comparison, the service life of the polymeric diamond saw blade is 4.23 times of that of the original conventional cold saw blade, and is obviously prolonged compared with the service life of the conventional polymeric diamond tool bit.

Description

technical field [0001] The invention relates to a polymerized diamond saw blade for metal cold sawing and a manufacturing process thereof. Background technique [0002] At present, the use of high-speed circular saws to cut metal materials is gradually replacing the traditional band saws due to the advantages of high cutting efficiency, good surface finish and high degree of automation. Silver-copper alloys, conventional ceramics and other fields cannot meet the requirements of sawing life; diamond has high hardness, high wear resistance, high compressive strength and excellent thermal conductivity, which makes it widely used in the processing of metals and hard and brittle materials. application, the disadvantage is that the material is not resistant to impact, and the saw teeth produced by this are prone to chipping and broken teeth, and there are still some shortcomings in the current welding process of the diamond and the saw blade body, as disclosed in the patent CN1023...

Problems solved by technology

[0002] At present, the use of high-speed circular saws to cut metal materials is gradually replacing the traditional band saws due to the advantages of high sawing efficiency, good surface finish and high degree of automation. However, hard alloy cold saw blades are used in phosphor copper alloys, Silver-copper alloys, conventional ceramics and other fields cannot meet the requirements of sawing life; diamond has high hardness, high wear resistance, high compressive strength and excellent thermal conductivity, which makes it widely used in the processing of metals and hard and brittle materials. application, the disadvantage is that the material is not resistant to impact, and the sawtooth produced by this is prone to chipping and broken teeth, and there are still some shortcomings in the welding process of the diamond and the saw blade body, as disclosed in the patent CN102319934B The brazing process of diamond saw blades, too high welding temperature will easily lead to slight deformation of the two materials, which cannot adapt to high-precision cutting

[0003] Patent CN203437753U discloses a diamond-toothed saw blade for processing aluminum profiles. The service life of the saw teeth is improved through the design of the rake angle and top width of the saw teeth. The combined effect of cutting heat and low-speed cutting will produce cutting tumors prematurely, causing the cutting edge of the tool to be covered by cutting tumors without wear, and the use effect is still not ideal
