[0046] (3) Preparation of diamond cutter head: The raw materials for the preparation of diamond cutter head are mixed according to the proportion, and then cold-pressed and sintered; during hot-pressing sintering, the sintering temperature is 790-850°C, and the pressure is 50-60kg / cm 2 , the holding time is 60 minutes; then the saw blade is trimmed with a grinder.
[0047] (4) Cold-pressed connection: After splicing the processed saw blade base and diamond cutter head, put it into the cold-pressed connection steel mold (because the size of the diamond cutter head is slightly larger than the gap between the teeth on the base body, so the diamond cutter after splicing Only part of the cone-shaped shank of the head extends into the gap between the saw teeth); fix the assembled cold-pressed connection steel mold on the workbench, and then use a press to apply a perpendicular to the diamond to both ends of the cold-pressed connection steel mold. The loading force F of the outer end...
Embodiment 1
[0050] The process that the present embodiment prepares the diamond saw blade is:
[0051] 1. Press Figure 1-2 Design the structure of the diamond saw blade and process the matrix.
[0052] 2. The raw material composition of diamond cutter head is (weight parts): 25 parts of copper, 40 parts of iron, 15 parts of nickel, 5 parts of cobalt, 6 parts of tin, 9 parts of rare earth, 8 parts of WC powder; 0.8 parts of liquid paraffin, 1.2 parts of diamond share.
[0053] Put the raw material of the cutter head into the mixing bucket and mix for 3 hours, then pour the powder into the mold for cold pressing, and then hot-press sintering. Hot pressing sintering temperature is 800℃, pressure is 60kg / cm 2 , the holding time is 60 minutes. After hot pressing and sintering, the grinding wheel abrasive belt grinds the cutter head. The prepared diamond bit has a uniform and dense structure, such as image 3 shown in (a). After testing, the hardness of the cutter head is 195HB, and the...
Embodiment 2
[0056] The process that the present embodiment prepares the diamond saw blade is:
[0057] 1. Press Figure 1-2 Design the structure of the diamond saw blade and process the matrix.
[0058] 2. The raw material composition of the diamond cutter head is (weight parts): 26 parts of copper, 37 parts of iron, 16 parts of nickel, 5 parts of cobalt, 8 parts of tin, 7 parts of rare earth Y, 8 parts of WC powder, 0.7 parts of liquid paraffin, 1.5 parts of diamond.
[0059] Put the raw material of the cutter head into the mixing bucket and mix for 3 hours, then pour the powder into the mold for cold pressing, and then hot-press sintering. Hot pressing sintering temperature is 805℃, pressure is 60kg / cm 2 , the holding time is 60 minutes. After hot pressing and sintering, the grinding wheel abrasive belt grinds the cutter head. The prepared diamond cutter head has a uniform and dense structure. After testing, the hardness of the cutter head is 194HB, and the mass wear loss of the a...
