Abstract
The utility model discloses a kind of dry cut type railway track drilling tool, including cutter hub and handle of a knife, cutter hub is provided with endoporus, and the cylindrical of cutter hub is provided with cutting edge, chip area is provided between cylindrical upper, the adjacent cutting sword of cutter hub；Cutting edge carries land, and land carries the post angle of back of tooth on certain length.The utility model reduces the contact area between tool surface and as-machined workpiece surface, reduces frictional force, reduces the generation of heat, in the case of no-cooling-water also can rapid drilling, improve drilling of the rail cutting-tool's used life.
Description
Technical field
It the utility model is related to a kind of drilling tool, specifically a kind of knife for the drilling of railway track dry cutting
Tool.
Background technology
At present, because Railway Site condition is poor, common drilling of the rail cutter is less in no-cooling-water or cooling water
In the case of, easily there is the problems such as burn, annealing, heavy wear because cooling down not in place in cutter tooth, has had a strong impact on making for cutter
Use the life-span.
The content of the invention
Technical problem to be solved in the utility model is to propose that one kind, can rapid drilling in the case of no-cooling-water
And the dry cut type railway track drilling tool of service life length.
To solve the above problems, a kind of dry cut type railway track drilling tool of the utility model includes cutter hub and handle of a knife, institute
State cutter hub and be provided with endoporus, the cylindrical of the cutter hub is provided with cutting edge, and the cylindrical of the cutter hub is gone up, between the adjacent cutting edge
Provided with chip area；The cutting edge carries land, and the land carries the post angle of back of tooth on certain length.
A kind of above-mentioned dry cut type railway track drilling tool, the width of the land are 0.6~1.5mm, after the post tooth
Angle length set on the land is 10mm~20mm, and the angle of the post angle of back of tooth is 2 °~12 °.
A kind of above-mentioned dry cut type railway track drilling tool, the handle of a knife and cutter hub integrally use high speed steel material
It is made.
The utility model is by adopting the above-described technical solution, its cutting edge carries land, land band on certain length
There is the post angle of back of tooth, so as to reduce the contact area between tool surface and as-machined workpiece surface, reduce frictional force, reduce heat
Produce, in the case of no-cooling-water also can rapid drilling, improve drilling of the rail cutting-tool's used life.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model cutter；
Fig. 2 is the left side of the utility model cutter to structural representation；
Fig. 3 is the mplifying structure schematic diagram of B-B sections in Fig. 1.
Embodiment
As depicted in figs. 1 and 2, the utility model, which does cut type railway track drilling tool, includes handle of a knife 1 and cutter hub 2, handle of a knife 1
It is made with the entirety of cutter hub 2 of high performance high speed steel material.Cutter hub 2 is provided with endoporus 3, and cutter hub 2 is cylindrical to be provided with cutting edge
4, the cylindrical of cutter hub 2 above, between adjacent cutting sword 4 is provided with a chip area 5, carries land 6 on cutting edge 4, land 6 is in a fixed length
Post angle of back of tooth a is carried on degree L（Please refer to shown in Fig. 3）.
As shown in figure 3, the width f of land 6 is 0.6~1.5mm, length L set on land 6 post angle of back of tooth a is
10mm~20mm, the post angle of back of tooth a angle are 2 °~12 °.
The intensity of cutter can be increased after the utility model cutter sets land on the cutting edge, during drilling, extend cutter
Service life.Meanwhile have back taper because cutter is cylindrical, when boring deeply to 10~20mm, cutter is cylindrical not to be wiped with workpiece, so
The grinding column angle of back of tooth only need to be set in 10~20mm of head.The grinding column angle of back of tooth reduces connecing for cutter and workpiece surface in drilling
Contacting surface is accumulated, and reduces the generation of heat.
