Abstract
The utility model provides a tooth reamer varies, the scalpel comprises a handle and a scalpel body, the cutter body is chamfer 45 with the handle of a knife and links up, be equipped with the sword tooth on the cutter body, the sword tooth has 8 on the circumference, 8 the anterior angle of individual sword tooth is 5~6, the relief angle is 21 in proper order, 15, 12, 12, 12, 12 with 21, margin width is 0.3mm in proper order, 0.4mm, 0.6mm, 0.6mm, 0.6mm, 0.6mm, 0.4mm and 0.3mm, the contained angle of adjacent sword intertooth space is 40 in proper order, 44, 46, 50, 48, 46, 44 with 42. According to reamer diameter size, rotational speed with feed the intensity determination tooth angle degree that varies, adopt the tooth pitch design that varies to the reamer for the reamer has a good shockproof effect, and according to the tooth angle degree that varies (being the tooth pitch), takes all factors into consideration each sword atress size, gives specific design to the margin width degree and the land relief angle size of every sword, thereby can guarantee that the processing blade has sufficient intensity on jar -proof basis, and the hole that just processes the gained has good smooth finish.
Description
Technical field
This utility model is related to a kind of machining cutter, more particularly to one kind tooth reamer such as not.
Background technology
Reamer has one or more cutters tooth, the rotary cutter to cut off machined hole surface sheet metal, with straight
The rotation finishing tool of sword or helical edges, for reaming or repaiies hole and uses.The reamer for currently using, blade is circumferentially
Point arrangement, its slot form and depth it is same it is cylindrical identical, each cutter tooth cutting output and cutting all along
Speed is all identical, and such work in-process is all identical due to workpiece and each tooth contact of cutting tooth so that the cycle can be produced during cutting
Property vibration, cutting resistance increase causes the hole surface that cuts with scissors out coarse and fineness is poor, there is polygon or axial striped
And spiral lamination, working life of reamer is relatively low.
Occur covibration in process to reduce workpiece and instrument at present, occur in that and do not wait tooth reamer designing, so
And the reamer of tooth design is not waited, when part is processed, cutting force suffered by cutter tooth is different before and after different space widths, existing design
The margin width of middle cutter tooth is not directed to foot in front and back and does not wait the design of tooth and be configured, the energy for bearing cutting force of each cutter tooth
Power is identical, but the cutting force being subject in process is different, which results in part cutter tooth and is easily damaged, and reduces making for reamer
Use the life-span.
Utility model content
The purpose of this utility model is to provide one kind not wait tooth reamer, can eliminate periodic vibration, and hole is repaiied in raising
The service life of fineness and reamer.
For achieving the above object, the utility model proposes do not wait tooth reamer, including handle of a knife and cutter hub, the cutter hub and knife
Handle is 45 ° of linkings of chamfering, and the cutter hub is provided with cutter tooth, and the cutter tooth circumferentially has 8, and the anterior angle of 8 cutters tooth is equal
For 5 °～6 °, relief angle is followed successively by 21 °, 15 °, 12 °, 12 °, 12 °, 12 ° and 21 °, the margin width of the cutter tooth successively 0.3mm,
0.4mm, 0.6mm, 0.6mm, 0.6mm, 0.6mm, 0.4mm and 0.3mm, the angle between the adjacent cutter tooth be followed successively by 40 °, 44 °,
46 °, 50 °, 48 °, 46 °, 44 ° and 42 °.
Compared with prior art, the beneficial effects of the utility model are：According to reamer diameter, rotating speed and feeding intensity
It is determined that not waiting tooth angle degree, reamer is designed using unequal blade spacing so that reamer has a good shockproof effect, and according to the tooth such as not
Angle (i.e. tooth pitch), considers each sword stress size, and the margin width and land relief angle size to every sword gives and specifically set
Meter, so as on the basis of shockproof, it is ensured that processing cutting edge has enough intensity, and the hole obtained by processing has good light
Cleanliness.
Description of the drawings
Fig. 1 is that the embodiment of this utility model one does not wait tooth reamer structural representation；
Fig. 2 is that the embodiment of this utility model one does not wait tooth reamer schematic cross-section.
Specific embodiment
Do not wait tooth reamer to be described in more detail to of the present utility model below in conjunction with schematic diagram, which show this
The preferred embodiment of utility model, it should be appreciated that those skilled in the art can change this utility model described here, and still
So realize advantageous effects of the present utility model.Therefore, description below is appreciated that extensive for those skilled in the art
Know, and be not intended as to restriction of the present utility model.
As shown in figure 1, the utility model proposes do not wait tooth reamer, including handle of a knife 1 and cutter hub 2, the cutter hub 2 and handle of a knife
1 is chamfering γ=45 ° linking, and the cutter hub 2 is provided with cutter tooth 3, and the cutter tooth 3 circumferentially has 8, as shown in figure 1,8
Cutter tooth is followed successively by the first cutter tooth 4, the second cutter tooth 5, the 3rd cutter tooth 6, the 4th cutter tooth 7, the 5th cutter tooth 8, the 6th cutter tooth 9, the 7th knife
The cutter tooth 11 of tooth 10 and the 8th, the anterior angle of 8 cutters tooth 3 is 5～6 °, and the relief angle of the cutter tooth 11 of the first cutter tooth 4 to the 8th is successively
For 21 °, 15 °, 12 °, 12 °, 12 °, 12 ° and 21 °, the margin width of the cutter tooth successively 0.3mm, 0.4mm, 0.6mm, 0.6mm,
