Existing drilling tool, the top of drilling tool body is protrude the drilling tool head arranged, the cylindrical or truncated cone-shaped of drilling tool body.Abrasion resistance is not high on the one hand, cannot be competent at the cutting of hard sharp rock, makes drilling tool be easy to wearing and tearing and lose efficacy; Shock resistance is poor on the other hand, and under high impact loads effect, be easy to cataclasm damage, thus application life is shorter, and the cost of construction operation is high.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of wear-resisting drilling tool, and this drilling tool improves drilling tool head, improves the abrasion resistance of drilling tool head.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
A kind of wear-resisting drilling tool, comprise drilling tool body, drilling tool head, the top of described drilling tool body is the drilling tool head given prominence to forward, and drilling tool body is circumferentially interval with sizing tooth in its contiguous drilling tool head part; Described drilling tool head and sizing increment head are taper.
The technical program is by improving drilling tool body, drilling tool body arranges sizing tooth, above-mentioned sizing tooth is arranged along the parts space that drilling tool body is being close to drilling tool head, when drilling tool creeps into, sizing tooth can reduce the wearing and tearing to drilling tool such as rock, and contribute to reducing that rock and drilling tool friction cause that drilling tool head temperature is too high, easy to wear under high temperature, abrasion resistance reduces.Confirm through on probation, the life-span of the drilling tool head of the technical program is 3-5 times of the life-span of original drilling tool head.
As the further improvement to the technical program, described drilling tool body is provided with fixing hole, and drilling tool head, sizing tooth are fixed by fixing hole.
By arranging fixing hole, above-mentioned drilling tool head, sizing tooth, fixed by fixing hole, and fixing mode can adopt the mode of welding, and connectivity robustness is good, stable work in work.
As the further improvement to the technical program, the degree of depth of described fixing hole be drilling tool head, sizing tine length 1/3 ~ 2/3.
Drilling tool head, sizing tooth are made by the alloy of high strength, high tenacity, and the degree of depth of fixing hole is dark, fixing good stability, but cost can increase, the degree of depth of preferred fixing hole be drilling tool head, sizing tine length 1/3.Stability maintenance is good, and cost is less.
As the further improvement to the technical program, the top of described drilling tool body is plane, and the center of plane is provided with fixing hole, and fixing hole fixes drilling tool head.
The basal diameter of drilling tool head and the ratio of drilling tool body end face diameter are 1:3 ~ 3:4, the warhead shape that the top of drilling tool head is curved, can reduce the resistance crept into when creeping into, and increase the life-span of drilling tool head.
As the further improvement to the technical program, described sizing tooth is circumferentially equally spaced at the first end of drilling tool body drilling tool.
Sizing tooth in the outer circumferentially layered distribution of the first end of drilling tool along drilling tool body, layer 2-4, the sizing tooth of every one deck is equally spaced in the circumferential, spaced distribution between layers, can ensureing when tunneling, drilling tool uniform force, increasing the abrasion resistance of drilling tool head further.
As the further improvement to the technical program, the angle in adjacent sizing tooth and drilling tool body axle center 30 °-72 °.
As the further improvement to the technical program, the angle in adjacent sizing tooth and drilling tool body axle center is 72 °.
As the further improvement to the technical program, described sizing tooth is three groups, and sizing tooth is arranged in vertical inclination.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of detailed description of the invention of the utility model.
Fig. 2 is the structural representation of the utility model the second detailed description of the invention.
Description of reference numerals: 1-drilling tool head; 2-fixing hole; 3-sizing tooth; 4-drilling tool body.
Detailed description of the invention
Below in conjunction with accompanying drawing 1-2, by example, the utility model is described in further detail.
Composition graphs 1 is known, and the wear-resisting drilling tool of one of the present utility model, comprises drilling tool body 4, drilling tool head 1, and the top of drilling tool body 4 is plane, and the center of plane is provided with fixing hole 2, and fixing hole 2 fixes drilling tool head 1.The top of described drilling tool body 4 is the drilling tool head 1 given prominence to forward, and drilling tool body 4 is circumferentially interval with sizing tooth 3 in its contiguous drilling tool head 1 part; Described drilling tool head 1 is taper with sizing tooth 3 termination.Drilling tool body 4 is provided with fixing hole 2, and drilling tool head 1, sizing tooth 3 are fixed by fixing hole 2.The degree of depth of described fixing hole 2 be drilling tool head 1, sizing tooth 3 length 1/3.
