Description
Technical field
The utility model relates to a kind of reamer, particularly relates to cold ladder moulding reamer in a kind of having.
Background technology
Reamer is the general utility tool in accurate hole on the processing parts, especially processes the first-selected instrument of the aperture of diameter below 50mm.And present existing reamer does not in use often reach expected effect, because cutter head drilling position is designed to form of grooves, can not remove allowance fully, the workpiece surface roughness that processes is bad, and chip removal has some setbacks, do not satisfy process requirements, working (machining) efficiency is low, and the machining hole precision is low, and cutter is not wear-resisting, service life is low, has increased processing cost.
Summary of the invention
The technical problems to be solved in the utility model overcomes above-mentioned the deficiencies in the prior art exactly, and a kind of reasonable in design is provided, and can satisfy process requirements, the machining accuracy height, cutter life height, processing cost is low have in cold ladder moulding reamer.
For solving the problems of the technologies described above, the technical solution of the utility model is:
Cold ladder moulding reamer in a kind of having, comprise cutter hub, cutter hub contains cutter head and handle of a knife, cold hole in being provided with in the cutter hub, described cutter head is step structure, and each ladder shaft part outer end is cutting portion, and each cutting portion is disposed radially the chip area of a plurality of cutting teeths and quantity correspondence, the cutting teeth of described cutter head outer end first cutting portion skips over the cutter hub central axis, and the cutting teeth blade first relief angle α of described first cutting portion is 15 °.
The cutting teeth blade second relief angle β of described first cutting portion is 5 °.
The described first cutting portion outer face is provided with groove structure.
Described step structure is made up of three grades of ladder shaft parts, and the cutting portion ecto-entad of described cutter head is followed successively by first cutting portion, second cutting portion and the 3rd cutting portion.
Cold hole is for along being parallel to cold through hole in two of cutter hub axis direction in described, is provided with a plurality of oblique cooling fluid apertures that penetrate the cutting teeth back of tooth that connect with interior cold through hole respectively in second, third cutting portion.
The beneficial effect of technical solutions of the utility model is:
1, structurally, ladder moulding reamer designing cold in the utility model has is reasonable, described cutter head is step structure, each ladder shaft part outer end is cutting portion, each cutting portion is disposed radially the chip area of a plurality of cutting teeths and quantity correspondence, in addition, adopt the cutter head outer end first cutting portion cutting teeth to cross the cutter hub central axis, and increase the angle of the first cutting portion cutting teeth blade, first relief angle, when processing work, can remove allowance fully like this, satisfy process requirements, and, cutting resistance also reduced, chip removal is smooth and easy, the surface of the work precision is higher, has also prolonged the service life of cutter simultaneously, has saved processing cost.
2, structurally, the first cutting teeth blade described in the utility model also is provided with second relief angle, further reduces the cutting resistance of process, prolongs the life-span of cutter; Cold hole is to be parallel to cold through hole in two of cutter hub axis direction in simultaneously described, be provided with in second, third cutting portion a plurality of with respectively in the oblique cooling fluid aperture that penetrates the cutting teeth back of tooth that connects of cold through hole, reasonable in design, effectively realize the cooling of cutter and processing work, further prolong the service life of cutter, improve working (machining) efficiency.
3, to sum up, ladder moulding reamer cold in the utility model has is simple in structure, reasonable in design, has improved working (machining) efficiency, has improved the machining accuracy of surface of the work, has prolonged cutter life, has saved processing cost, therefore, is very suitable for promotion and implementation.
