Abstract
The technical solution of the utility model is a kind of prewave sword necking tool, including cutter hub, the cutter hub leading portion is evenly arranged with multiple blades, and helix chip space is provided between two adjacent edges, and the helical angle of the blade is the interaction helical angle that 30 ° of helical angles and 26 ° of helical angles form.The utility model cutting resistance is small, and the fast effect of chip removal speed is good, and stock-removing efficiency is high, is not easy tipping in cutting process.
Description
Technical field
The present invention relates to a kind of necking tools, more particularly, to a kind of prewave sword necking tool.
Background technique
The spirals such as necking tool is common a kind of cutter on mechanical processing industry lathe, and necking tool currently on the market is all
The milling cutter at angle is easy to produce vibration knife when encountering overhanging length or irregular workpiece shapes, generates noise, the workpiece that simultaneous processing comes out
Surface roughness is poor, and cutting edge is easy tipping.
Summary of the invention
In view of the above-mentioned problems, chip removal speed is imitated fastly the present invention is intended to provide a kind of prewave sword necking tool, cutting resistance is small
Fruit is good, and stock-removing efficiency is high, is not easy tipping in cutting process.
The technical scheme is that a kind of prewave sword necking tool, including cutter hub, the cutter hub leading portion are evenly arranged with more
A blade, helix chip space is provided between two adjacent edges, and the helical angle of the blade is 30 ° of helical angles and 26 ° of spiral shells
The interaction helical angle of swing angle composition.
Preferably, the section of the chip space is arc-shaped.
Preferably, the chip space and cutter hub end face junction are arc groove transition.
Preferably, the blade rake face is provided with negative chamfered edge.
Preferably, chamfered at the point of a knife of the blade.
Preferably, AlCrN coating is coated on the cutter hub, coating hardness reaches HV3000-4000.
Preferably, the cutter hub is formed using superfine ultra micron material at high temperature sintering adhesive bonding.
Preferably, the quantity of the blade is 4, is along the circumferential direction angularly evenly arranged.
The present invention, so that blade is to become helical structure, is made during the cutting process by designing a kind of completely new blade angle
Stress when obtaining blade difference, effectively reduces cutting resistance, reduces cutting vibration, improve stock-removing efficiency, in cutting process
In be not easy tipping, improve cutting-tool's used life.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention；
Fig. 2 is the top view of Fig. 1；
Wherein: 1-cutter hub；2-blades；3-chip spaces.
Specific embodiment
With reference to the accompanying drawing, invention is further described in detail.
As shown in Figure 1 to Figure 2, the technical scheme is that a kind of prewave sword necking tool, including cutter hub 1, the cutter hub 1
Leading portion is evenly arranged with multiple blades 2, and helix chip space 3, the spiral of the blade 2 are provided between two adjacent edges 2
Angle is the interaction helical angle that 30 ° of helical angles and 26 ° of helical angles form.
Preferably, the section of the chip space 3 is arc-shaped, molding circular arc chip space design, so that chip space is big, row
It considers to be worth doing more smoothly.
Preferably, the chip space 3 and 1 end face junction of cutter hub are arc groove transition, and iron filings are discharged more with slot bottom
It is smooth, reduce chip resistance.
Preferably, 2 rake face of blade is provided with negative chamfered edge, so that cutting edge is strongr, increases cutter rigidity and intensity,
And the impact resistance ability of cutting edge.
Preferably, chamfered at the point of a knife of the blade 2, chamfering value are 0.1-0.15mm, in process, enhancing
The impact resistance of point of a knife, effective protection point of a knife reduce the probability of point of a knife tipping.
Preferably, AlCrN coating is coated on the cutter hub 1, coating hardness reaches HV3000-4000, increases tool blade
The wear-resisting property of mouth improves cutter life.
Preferably, the cutter hub 1 is formed using superfine ultra micron material at high temperature sintering adhesive bonding, enhances the rigidity of cutter, together
When there is good impact resistance, avoid cutter from because material is too crisp causing cracking of cutter in processing.
Preferably, the quantity of the blade 2 is 4, is along the circumferential direction angularly evenly arranged.
This prewave sword necking tool that the present invention designs, novel geometry are related to that cutting of quickly slotting may be implemented
And chip removal, stock-removing efficiency is high, while blade rigidity and intensity are good, it is not easy to tipping, long service life.
The above is only better embodiment of the invention, not makes any form of restriction to invention, it is all according to
According to technical principle any simple modification, equivalent variations or modification made to the above embodiment of the invention, the present invention is still fallen within
In the range of technical solution.
