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, the hole precision height of processing, and process is steady, prolongs cutter life, the ring flange that cuts down finished cost switching shank type reamer.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of ring flange switching shank type reamer, comprise cutter hub, cutter hub contains cutter head and handle of a knife, the junction of cutter head and handle of a knife is set to flange plate structure, the cutter head outer end along the circumferential direction is provided with the chip area of a plurality of cutting teeths and respective amount, and coupling is installed with blade on each cutting teeth, and the cutter head outer end is slightly stretched out in the blade outer end, described chip area adopts asymmetric arrangement, and the angle of described blade blade and cutter hub axis direction is 6 °.
The relief angle of described blade cut sword is 12 °.
The quantity of described cutting teeth is six.
The angular range of adjacent two cutting teeths is 55 °-65 °.
The angle of the chip area both sides portion corresponding with described cutting teeth is 75 °.
Staggered a plurality of connection stepped holes and the connecting thread hole of being evenly equipped with on the described flange plate structure.
In cutter hub, start from the handle of a knife outer end along the cutter hub axis direction and be provided with the cooling fluid blind hole, be provided with a plurality of oblique cooling fluid apertures that penetrate the cutting teeth back of tooth that connect with the cooling fluid blind hole in the cutter head.
Be provided with locating hole in center, cutter head outer face.
The beneficial effect of technical solutions of the utility model is:
Cutting edge is sharp, the precision height, and process is steady, axiality height, cutter life height!
1, structurally, the utility model ring flange switching shank type reamer designing is reasonable, sets up tool orthogonal rake, and the plastic deformation in the time of can reducing rake face extruding cutting lay reduces the smear metal frictional resistance of rake face of flowing through, thereby reduced cutting force, heat in metal cutting and power; In addition, chip area adopts asymmetric arrangement to help cutter to remain stable diameter in the working angles in whole hole, eliminates beat and not only can improve the quality in hole, and can reduce the tool wear degree significantly, prolongs cutter life, cuts down finished cost.
2, structurally, be provided with cooling passage in the utility model cutter hub, realize the cooling of cutter and processing work, prolong the service life of cutter, improve working (machining) efficiency; Simultaneously, in the cutter head outer end locating hole is set, is used for the location of the preceding cutter of processing, easy to use.
3, to sum up, the utility model ring flange switching shank type reamer reasonable in design, cutting edge is sharp, the machining accuracy height, process is steady, the axiality height, cutter life, therefore height, was very suitable for promotion and implementation.
