Abstract
The invention discloses a high-strength drill bit. The high-strength drill bit is composed of, by weight, 5-11 parts of molybdenum, 6-8 parts of nickel, 6-15 parts of hafnium, 2-3 parts of titanium, 2-3 parts of chromium, 3-6 parts of titanium, 0.5-2 parts of vanadium, 2.4-2.6 parts of tin, 0.14-0.18 part of lanthanum, 3.2-3.5 parts of zinc, 0.6-0.9 part of niobium carbide, 0.9-1.2 parts of tungsten carbide, 0.12-0.16 part of thallium trioxide and 0.73-0.82 part of aluminum oxide. The rigidity of the high-strength drill bit is 8-10 times of that of an existing product, and meanwhile the toughness of the high-strength drill bit is greatly improved. Experiments show that the toughness of the high-strength drill bit can be improved by more than 20%.
Description
Technical field
The present invention relates to lathe spare part technical field, especially a kind of High-strength drill bit.
Background technology
High-strength drill bit goes out through hole or blind hole in order to drilling on solid material, and can to the cutter of existing hole reaming.High-strength drill bit can be divided into roughing with and fining-off, the High-strength drill bit of roughing generally has very large cutting output, understands like this and cause very large wearing and tearing to cutting edge in the process of cutting.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, propose a kind of High-strength drill bit, structure is ingenious, easy to use.
In order to realize foregoing invention object, the invention provides following technical scheme: a kind of High-strength drill bit, adopting the composition of following weight parts to make:
Molybdenum 5-11 nickel 6-8 hafnium 6-15 titanium 2-3 chromium 2-3
Titanium 3-6 vanadium 0.5-2 tin 2.4-2.6 lanthanum 0.14-0.18
Zinc 3.2-3.5 niobium carbide 0.6-0.9 tungsten carbide 0.9-1.2
Thallic oxide 0.12-0.16 alundum (Al2O3) 0.73-0.82.
Further, the weight portion of each composition is:
Molybdenum 6 nickel 8 hafnium 9 titanium 2.3 chromium 2.3
Titanium 6 vanadium 1.5 tin 2.6 lanthanum 0.16
Zinc 3.3 niobium carbide 0.8 tungsten carbide 1
Thallic oxide 0.13 alundum (Al2O3) 0.78.
Compared with prior art, the present invention has the following advantages: this product hardness is 8-10 times of existing product, and meanwhile, its toughness also improves a lot, and experiment shows, its toughness of High-strength drill bit provided by the invention can promote more than 20%.
