Description
Technical field
The utility model relates to cutting-tool engineering fields, and in particular to a kind of bloom rose reamer.
Background technique
Powder metallurgy is to produce metal powder or made with metal powder (or mixture of metal powder and non-metal powder)
The technology of metal material, composite material and various types product is manufactured through overmolding and sintering for raw material.Due to powder
The advantages of last metallurgical technology, it has become the key for solving the problems, such as new material, plays in the development of new material very important
Effect.
The green compact as made of powder compacting, internal hole cannot completely eliminate, and existing bloom rose reamer is generally adopted
With right angle blade, using point cutting when processing, it is prone to wear and collapses scarce, when processing powdered metallurgical material, stomata easily occur, and due to
Hardness reaches 330HV, easily causes the abrasion of cutting edge roundness, causes cutter life relatively low, is not able to satisfy production requirement.
Utility model content
The purpose of this utility model is that aiming at the shortcomings in the prior art, and a kind of bloom rose reamer is provided, the bloom
Rose reamer can play the role of extruding in processing, and the stomata of work piece can be filled out, thus the stomata avoided
It generates.
The purpose of this utility model is achieved through the following technical solutions:
A kind of bloom rose reamer is provided, have longitudinal axis comprising shank section and be located at its end cutting portion, it is described
Cutting portion be equipped with cutting edge and chip space, cutting edge be equipped with it is a plurality of, between cutting edge, the cutting edge is equipped with chip space
Corner portion, the corner portion are circular arc chamfering.
Wherein, the corner portion is evagination circular arc chamfering.
Wherein, AlCr coating is coated on the cutting edge.
Wherein, the cutting edge and longitudinal axis are in 24 ° of angles.
Wherein, the cutting edge uses polishing treatment.
Wherein, the transverse plane d of the cutting edge front end is 2mm.
Wherein, it is equipped between the cutting edge and the chip space for cutting the resigning portion stepped down.
Wherein, the diameter of the shank section is greater than the diameter of cutting portion.
Wherein, the cutting edge is provided with three.
The utility model has the beneficial effects that the bloom rose reamer of the utility model, cutting edge is equipped with corner portion, and corner portion is
Circular arc chamfering is cut when processing using entire arc surface, and can play the role of extruding, stomata can be filled out in extrusion process
Get up, thus the generation of the stomata avoided, so that the longer life expectancy of cutter.
Detailed description of the invention
Using attached drawing, the utility model is described in further detail, but the embodiment in attached drawing is not constituted to the utility model
Any restrictions for those of ordinary skill in the art without creative efforts, can also be according to following attached
Figure obtains other attached drawings.
Fig. 1 is the structural schematic diagram of the bloom rose reamer of the utility model.
Fig. 2 is the partial enlarged view of cutting portion in Fig. 1.
Fig. 1 includes into Fig. 2:
Longitudinal axis A, shank section 1, cutting portion 2, cutting edge 3, corner portion 30, resigning portion 31, chip space 4.
Specific embodiment
The utility model is further described with the following Examples.
A kind of specific embodiment of bloom rose reamer of the utility model, as Figure 1-Figure 2, bloom rose reamer has
Longitudinal axis A, bloom rose reamer include shank section 1 and with the cutting portion 2 that is located at its end, the diameter of shank section 1 is greater than cutting portion 2
Diameter, shank section 1 and cutting portion 2 be an integral molding structure, and facilitates the manufacturing, improves production efficiency.Described in the present embodiment
Bloom rose reamer, the non-stick knife in chip removal, cutting portion 2 be equipped with cutting edge 3 and chip space 4, the cooling effect of cutting portion 2
It is good, the abrasion of cutting edge 3 can be effectively reduced, its service life is extended.
Cutting edge 3 be used for cutting workpiece, and cutting edge 3 be equipped with it is a plurality of, in the present embodiment, cutting edge 3 be equipped with three, three
Bloom rose reamer is cut into three parts by the symmetrical cutting edge 3 of item, and cutting edge 3 is equipped with corner portion 30, and corner portion 30 is circular arc chamfering,
And further, corner portion 30 is evagination circular arc chamfering.Existing bloom rose reamer generally uses right angle point of a knife, and when processing uses point
Cutting, be prone to wear collapse it is scarce, process powdered metallurgical material when, easily there is stomata.In the present embodiment, entire circular arc is used when processing
Face cutting, and extruding can be played the role of, stomata can be filled out in extrusion process, thus the generation of the stomata avoided,
So that the longer life expectancy of cutter.On cutting edge 3 be coated with AlCr coating, for increasing the hardness of cutting edge 3 so that cutter more resistant to
Mill.Further, cutting edge 3 and longitudinal axis A are in 24 ° of angles, so that during cutting, the contact surface of cutting edge 3 and workpiece
Product is bigger, and cutting is more convenient, and cutting edge 3 uses polishing treatment, is polished, can be effectively eliminated using the sand of 300 mesh
The sawtooth that cutting edge roundness generates in grinding process, to increase cutting-tool's used life.
For chip space 4 between adjacent cutting edge 3, chip space 4 is used to cut the clast discharge come, facilitates cutter
Processing there are three the quantity of the corresponding cutting edge 3 of chip space 4 is also provided with, and is provided with resigning portion between cutting edge 3 and chip space 4
31, resigning portion 31 is used to step down when processing, prevented from cutting, and resigning portion 31 is arranged, and further increased cutting edge 3
Intensity.The end face plane d of the front end of cutting edge 3 is that 2mm (is simultaneously by the diameter of a circle at three 3 sword ends of cutting edge
0.5mm), while the tough of cutting edge 3 can be improved so that bloom rose reamer facilitates knife accurate when processing in the setting of transverse plane
It spends, at this time bloom rose reamer longest-lived of the bloom rose reamer with respect to other sizes.
Finally it should be noted that above embodiments are only to illustrate the technical solution of the utility model, rather than to this reality
With the limitation of novel protected range, although being explained in detail referring to preferred embodiment to the utility model, this field it is general
Lead to it will be appreciated by the skilled person that can be with the technical solution of the present invention is modified or equivalently replaced, without departing from this
The spirit and scope of utility model technical solution.
