Embodiment 1

[0015] refer to figure 1 , orderly positioning the weakened carcass to form an ultra-thin gear-shaped diamond saw blade, including the installation hole 1 and the carcass working layer 2. Diamond particles 4 and weakened carcass particles 3 arranged in order are distributed all over the carcass working layer 2 . The saw blade after cutting and working, the diamond particles 4 protrude from the blade, the weakened carcass particles fall off and appear pits 5, automatically forming a gear-shaped working surface. Saw blade diameter Φ30mm, thickness 0.3mm, installation hole Φ10mm, carcass working layer formula (mass ratio): cobalt powder 40%, nickel powder 10%, iron powder 10%, chromium powder 5%, copper powder 30%, tin powder 5%, the powder particle size is less than 45 microns; the diamond volume concentration is 2%, and the particle size is 150-178 microns; Arranged radially and orderly.

Abstract

The invention discloses an orderly-positioned weakening matrix self-forming ultra-thin gear-shaped diamond saw blade. The orderly-positioned weakening matrix self-forming ultra-thin gear-shaped diamond saw blade is manufactured by adopting a powder metallurgy method, the diameter of the saw blade ranges from 30 mm to 400 mm, the thickness of the saw blade ranges from 0.2 mm to 2.0 mm, and the sawblade comprises a matrix working layer and a mounting hole; metal powder, a diamond and weakening matrix particles are selected as raw materials for the matrix working layer; an organic solvent is added into the metal powder and the diamond to be prepared into a slurry, the slurry is poured into a mold for forming, and an ultra-thin saw blade blank is made after vacuum baking and low-temperature sintering; and the weakening matrix particles are arranged in order according to the design concentration, and embedded in a preset position of the blank, and then the saw blade is manufactured by adopting a hot-pressing sintering process. According to the ordered positioning weakening matrix self-forming ultra-thin gear-shaped diamond saw blade and the manufacturing process thereof, the weakeningmatrix particles can fall off automatically in the cutting working process, so that the working end face of the ultra-thin saw blade is in a gear shape, and the ultra-thin saw blade has the advantagesthat the efficiency is high, the service life is long and energy consumption is low, and is good for saving resources and energy.

Description

technical field [0001] The invention mainly belongs to the fields of mechanical processing and powder metallurgy. The powder metallurgy hot-pressing sintering technology is used to implant orderly positioned and distributed structure weakened carcass particles, and in particular relates to an ultra-thin gear-shaped working surface structure diamond saw blade and its manufacturing process. Background technique [0002] General-purpose diamond saw blades are thicker and use more materials. In the processing of thin plates, ultra-thin plates, and precious materials, the slits are wide and the material utilization rate is low, resulting in huge waste of resources; Large resistance, poor sharpness, low work efficiency and high power consumption are not conducive to saving energy. Orderly positioning and weakening the carcass to form an ultra-thin gear-shaped diamond saw blade can effectively solve the above problems. Contents of the invention [0003] The object of the present...
