Problems solved by technology

Cobalt-based diamond saw blades have the advantages of high hardness and good wear resistance, but are expensive and have a high sintering temperature. The development trend is to replace cobalt-based with low-cobalt or non-cobalt-based
The advantages of iron-based diamond saw blades are low price and simple production process, but poor toughness and self-sharpening
The sintering temperature of copper-based diamond saw blade is low, the price is low, and the toughness is good, but the wear resistance is poor. The saw blade is easy to wear during the cutting process, which seriously affects the life of the diamond saw blade.

Embodiment 1

[0014] Pure copper powder (Cu): 36%, iron powder (Fe): 17%, nickel powder (Ni) 8%, tungsten carbide (WC): 4%, tin powder (Sn): 7%, bronze powder (Cu -10Sn): 28%, after mixing evenly, add abrasive grade diamond concentration 16% and nanoscale diamond concentration 2% and mix evenly again, finally add liquid paraffin and mix. Put the mixed molding material and the steel matrix of the saw blade into a cold-press mold for cold-press molding, put it in a bell furnace after demoulding, and sinter in a hydrogen reducing atmosphere at a sintering temperature of 880°C, keep warm for 60 minutes, and keep warm for 55 minutes Start to pressurize at 40KN, keep the pressure for 5 minutes, cool down and get the diamond saw blade, sharpen the saw blade, and use Fujian 603 granite plate as the sawing object for actual cutting. The plate specification: length 660mm, thickness 20mm. The dry cutting was repeated 6 times for each saw blade, and the diameter before sawing and the diameter after saw...

Embodiment 2

[0021] Pure copper powder (Cu): 37.9%, iron powder (Fe): 20%, nickel powder (Ni): 10%, tungsten carbide (WC): 2%, tin powder (Sn): 6.1%, bronze powder (Cu -10Sn): 24%. The concentration of abrasive grade diamond is 18%. The nanoscale diamond concentration is 5%. The preparation process is the same as above, and the calculation method of the service life of the saw blade is the same as above.

[0022] After calculation, the service life of the saw blade is 128.9m, compared with the 105m service life of similar products on the market, the service life of the saw blade has increased by 22.8%.

Embodiment 3

[0024] Pure copper powder (Cu): 40%, iron powder (Fe): 22%, nickel powder (Ni): 12%, tungsten carbide (WC) 1%, tin powder (Sn): 4%, bronze powder (Cu- 10Sn): 21%. The concentration of abrasive grade diamond is 20% and that of nanoscale diamond is 10%. The preparation process is the same as above, and the calculation method of the service life of the saw blade is the same as above.

[0025] After calculation, the service life of the saw blade is 121.7m, which is 15.9% higher than the service life of similar products on the market which is 105m.

[0026] After testing, the copper-based diamond saw blade prepared according to the above formula has good wear resistance, and the purpose of the invention has been achieved.

Abstract

The invention relates to a copper base diamond saw blade, which comprises a cutter head and a steel base body and is characterized in that the cutter head is made by mixing and firing metal powder, abrasive grade diamond and nano grade diamond; and the metal powder comprises pure copper powder, iron powder, nickel powder, tungsten carbide, tin powder and bronze powder. The preparation method comprises the steps of: uniformly mixing the metal powder according to a proportion; sequentially adding the abrasive grade diamond and the nano grade diamond for mixing; finally adding liquid olefin; packing the mixed formed material into a cold pressing mould to form; and sintering to prepare the diamond saw blade. Compared with the prior art, the diamond saw blade has the advantage that the abrasive grade diamond and the nano grade diamond are simultaneously added in the saw blade for achieving the purpose of organically combining the cutting function of the abrasive grade diamond with the friction-reducing abrasion resistant function of the nano grade diamond, therefore, the copper base diamond saw blade has effective sawing performance and better abrasion resistant performance. Compared with a similar saw blade, the copper base diamond saw blade has obviously enhanced service life by a test.

Description

technical field [0001] The invention relates to a diamond saw blade, in particular to a wear-resistant copper-based diamond saw blade, which is suitable for processing granite and marble. Background technique [0002] The most common tool for sawing stone is a diamond saw blade, and its performance is the key to determining the cost and efficiency of stone processing. Diamond saw blades consist of three parts: diamond, bond, and matrix. Diamond saw blades are roughly classified into cobalt-based diamond saw blades, iron-based diamond saw blades and copper-based diamond saw blades according to different types of binders. According to different cutting objects, choose different binder products. Cobalt-based diamond saw blades have the advantages of high hardness and good wear resistance, but are expensive and have a high sintering temperature. The development trend is to replace cobalt-based with low-cobalt or non-cobalt-based. The advantages of iron-based diamond saw blade...
