Abstract
The utility model provides a multiple-cutting-edge reamer which comprises a reamer handle and a reamer body connected with the reamer handle into a whole. Six blades are arranged at a cutting end of the reamer body, each blade is arranged on a primary structure, and a counter bore is formed in the cutting end face of the reamer body. By adopting un-equant six-blade distribution, the multiple-cutting-edge reamer is simple in structure and is capable of guaranteeing center degrees and concentricity. Due to the fact that the counter bore is formed in the cutting end face of the reamer body, a center bore is not easy to damage in processing, the center bore can be guaranteed in good condition, surface roughness of a processed workpiece is good, and cylindricity is well processed. Due to the fact that cooling passages are arranged in the reamer handle and the reamer body, six cooling holes respectively corresponding to the six blades and connected with the cooling passages are formed in the reamer body, cutting fluid is enabled to cover processing positions completely, generation of cutting heat is resisted effectively, chip removal of a chip groove is enable to be smooth, and processing at a high speed and high efficiency is guaranteed. Due to the fact that six chip grooves which respectively corresponding to the six blades are formed in the reamer body and the six chip grooves are distributed on the reamer body in a nonsymmetrical mode, smooth chip removal is guaranteed.
Description
Technical field
The utility model belongs to the cutting tool technical field, particularly a kind of multiple-cutting-edge reamer.
Background technology
At present, the hole concentricity that traditional reamer processes is good not, and the reamer front end adds easy lesion center hole in man-hour without counterbore, can not guarantee that centre bore is intact, and the workpiece surface roughness that processes is poor, cylindricity is poor, subtracts few Xiu mill number of times, and cutter life is short.
The utility model content
The utility model provide a kind of simple in structure, crudy good and the multiple-cutting-edge reamer of long service life.
For achieving the above object, the technical solution of the utility model is: a kind of multiple-cutting-edge reamer, comprise handle of a knife and the cutter hub that is connected as a single entity with handle of a knife, and the cutting end of described cutter hub is provided with six blades, and blade is located on the matrix; The cutting end face of cutter hub is provided with counterbore.
Be provided with cooling passage in described handle of a knife and the cutter hub, cutter hub be provided with six respectively with six blade Cooling Holes corresponding, that be connected with cooling passage.
Described cutter hub be provided with six respectively with six chip areas that blade is corresponding, six chip area asymmetric distribution are on cutter hub.
The cutter head relief angle of described blade is 15 °.
Compared with prior art, the utility model has the advantages that:
1, the utility model comprises handle of a knife and the cutter hub that is connected as a single entity with handle of a knife, and the cutting end of described cutter hub is provided with six blades, and blade is located on the matrix, and it adopts the not six swords distribution of five equilibrium, and is simple in structure, can guarantee center of circle degree and concentricity; The cutting end face of cutter hub is provided with counterbore, adds and is difficult for the lesion center hole man-hour, can guarantee that centre bore is intact, and the workpiece surface roughness that processes is good, and cylindricity processing is intact.
2, be provided with cooling passage in handle of a knife and the cutter hub, cutter hub be provided with six respectively with six blade Cooling Holes corresponding, that be connected with cooling passage, can make cutting fluid cover working position fully, can effectively resist the generation of heat in metal cutting, make the chip area chip removal more smooth and easy, guarantee high-speed and high-efficiency processing; Cutter hub be provided with six respectively with six chip areas that blade is corresponding, six chip area asymmetric distribution guarantee that chip removal is smooth and easy on cutter hub.
3, the utility model allowing blade replacement more can increase greatly Xiu mill number of times, and cutter life is long.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is chip area distribution schematic diagram among Fig. 2.
The specific embodiment
Such as Fig. 1, Fig. 2 and multiple-cutting-edge reamer shown in Figure 3, it comprises handle of a knife 1 and the cutter hub 2 that is connected as a single entity with handle of a knife 1, is provided with cooling passage 3 in handle of a knife 1 and the cutter hub 2.Be provided with six blades 5 in the cutting end of cutter hub 2, blade 5 is located at respectively on the corresponding matrix 4, and the cutter head relief angle α of blade 5 is 15 °, and blade 5 is the PCD blade.Cutter hub 2 be provided with six respectively with six blades, 5 Cooling Holes 6 corresponding, that be connected with cooling passage 3.Simultaneously, cutter hub 2 be provided with six respectively chip area 7, six chip area 7 asymmetric distribution corresponding with six blades 5 on cutter hub 2.In order to guarantee that centre bore is intact, be provided with counterbore 8 at the cutting end face of cutter hub 2.
In the present embodiment, the diameter of handle of a knife 1 interior cooling passage 3 is 5mm, and the diameter of cutter hub 2 interior cooling passages 3 is 4mm; The diameter of Cooling Holes 6 is 1mm, and the angle of six Cooling Holes 6 center lines and cutter hub 2 axis is respectively 20 °, 25 °, 30 °, 20 °, 25 ° and 30 °; Angle between six chip areas 7 is respectively 63 °, 59 °, 58 °, 63 ° and 59 °, to satisfy the asymmetric distribution of six chip areas 7 on cutter hub 2.
