Description
Technical field
The utility model is related to metal cutting process cutting-tool engineering field, more particularly to a kind of PCD welding fabrications reamer.
Background technology
Reamer is the general utility tool for processing precision holes on part.And existing reamer is not in use often up at present
To expected effect, not enough, blade abrasion is fast in process, and reamer service life is shorter for processing finish, and overall hard
Matter alloy reamer is with high costs.
In the last few years, with the development of science and technology, machining level is improved on the whole, needed for industrial all departments
The precision level of workpiece is improved constantly, and this requires that machinery manufacturing industry can more subtly process workpiece.At present, in the market lacks
The now defective new reamer for welding hard alloy can be overcome less.
Utility model content
Goal of the invention of the present utility model is：For drawbacks described above, there is provided a kind of PCD welding fabrications reamer, Neng Gouti
The finish of ladder high, it is ensured that hole dimensional accuracy, while can carry out strand to multiple steps cuts processing.
The technical solution adopted in the utility model is such：A kind of PCD welding fabrications reamer, including cutter hub, after cutter hub
End is provided with handle of a knife, and cutter hub center is provided with interior cold hole, it is characterised in that：The handle of a knife is provided with origin reference location, the cutter hub front end
Be provided with multiple steps, the cutter hub front end is provided with cutter groove, the cutter groove be all provided with the multiple step it is fluted, it is described recessed
Slot welding is connected to hard alloy, and PCD blades, the cutter groove, hard alloy and PCD knife face tables are welded with the Carbide Step
Face is on the same plane.
The multiple step is three steps, and three steps include first step, second step, the 3rd step, institute
First step is stated for right angle step, the second step is band chamfering step, the 3rd step is 45oStep.
The a diameter of 11mm of cutter hub front end surface, a diameter of 15mm of first step, the second step is a diameter of
20mm, the 3rd stepped diameters are 23mm.
The interior cold hole is small in cutter hub end aperture, big in cutter hub shank aperture.
The interior cold hole is provided with multiple Cooling Holes in cutter groove part.
In sum, by adopting the above-described technical solution, the beneficial effects of the utility model are：For being molded shoulder hole
Finishing, improve the finish of ladder, it is ensured that hole dimensional accuracy, while carrying out strand to multiple steps cuts machine-shaping, welding
PCD greatlys save processing cost, and cooling cutter improves cutter life when setting interior cold hole machined.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Marked in figure：1 is handle of a knife, and 2 is interior cold hole, and 3 is cutter groove, and 4 is hard alloy, and 5 is PCD blades, and 6 is First
Rank, 7 is second step, and 8 is the 3rd step, and 9 is Cooling Holes, is positioned on the basis of 10.
Specific embodiment
