Embodiment 1
[0024] Referring to the accompanying drawings, the matrix-containing diamond drill bit impregnated with pores for geological exploration in this embodiment includes a steel body 5 and a matrix 1, the matrix 1 is located on the steel body 5, and an inner water tank is provided on the steel body 5 2. Nozzle 3, outer water tank 4, diamond 6 and air holes 7 are arranged in the carcass 1.
[0025] In this embodiment, the pores are spherical in shape with a diameter of 0.3-0.8 mm, and are evenly distributed in the working layer of the carcass. Among them, the total volume of pores accounts for 12.3% of the total volume of the carcass working layer.
[0026] Take the 8mm working layer carcass of the 75 / 49 rope drill as an example.
[0027] The manufacturing process includes the following steps:
[0028] (1) Weigh NaHCO 3 1.6g, glycerol 0.9g, the NaHCO 3 Add glycerin and stir evenly;
[0029] (2) Add 96.3g of matrix formula powder and 10.7g of diamond (GE960, particle size 30-40...
Embodiment 2
[0033] The carcass impregnated diamond drill bit with pores in this embodiment includes a steel body 5 and a carcass 1, the carcass 1 is located on the steel body 5, and the steel body 5 is provided with an inner water tank 2 and a nozzle 3 , The outer water tank 4, the carcass 1 is provided with diamonds 6 and air holes 7.
[0034] In this embodiment, the pores are spherical in shape with a diameter of 0.6-1.0 mm, and are evenly distributed in the working layer of the carcass. Among them, the total volume of pores accounts for 23.5% of the total volume of the carcass working layer.
[0035] The manufacturing process includes the following steps:
[0036] (1) Weigh (NH 4 ) 2 SO 4 1.1g, glycerol 0.4g, the weighed (NH 4 ) 2 SO 4 Add glycerin and stir evenly;
[0037] (2) Add 96.3g of matrix formula powder and 10.7g of diamond (GE960, particle size 30-40 mesh), among which, the matrix formula powder is: by mass ratio, 663 bronze powder: iron powder: tin powder: Nickel p...
