Description
Technical field
The utility model relates to a kind of cutter, particularly relates to a kind of drum cutter for processing housing inside groove.
Background technology
Drum knife is in order to the complex-curved cutter of converted products, and particularly, drum knife is used for the interior channel profiles of processing mobile phone housing or electronic product casing.Current in processing mobile phone housing or electronic product casing during channel profiles, need on lathe, adopt multiple knife combination to carry out tool changing processing, this knife combination structure clumsy and tool changing processing is compared and is lost time, reduce operating efficiency, next also reduces the precision of the interior channel profiles of handset shell.
Summary of the invention
In view of the above, the utility model is necessary to provide the precision of the interior channel profiles of a kind of processing mobile phone housing or electronic product casing high and the drum cutter for processing housing inside groove of delicate structure.
The technical scheme that the utility model provides is as follows: a kind of drum cutter for processing housing inside groove, comprise cutter hub and knife bar, described knife bar is installed on the axial line in the middle part of cutter hub, described cutter hub comprises the lower end of upper end in drum organization and cylindrical-shaped structure, the lower end of described cutter hub forms escape groove, the upper end of described cutter hub offers the edge of a knife about the axial line of cutter hub outside cutter hub, the described edge of a knife is connected with diamond and forms blade, described adamantine outer face is higher than the outer face of cutter hub.
Further, the upper end of described cutter hub is radius is the drum organization that the arcwall face of 3.75mm and the top and bottom of upper end intersect formation.
Further, described knife bar comprises the top of round table-like structure and the bottom of cylindrical-shaped structure.
Further, the length of described knife bar is 45mm, the cylinder of to be diameter be in the bottom of described knife bar 6mm, and the bottom of described bottom offers the chamfering of 1mm × 45 degree.
Compared with prior art, the utility model forms blade for the drum cutter processing housing inside groove by offering the edge of a knife and weld diamond on cutter hub on the edge of a knife, during the interior channel profiles of processing mobile phone housing or electronic product casing, without the need to carrying out tool changing processing, operating efficiency is high, secondly, edge wear is little, stability is strong, the machining accuracy of interior channel profiles is high, and this is for processing the drum cutter delicate structure of housing inside groove, saves material.
Accompanying drawing explanation
Fig. 1 is that the utility model is for processing the front view of the drum cutter of housing inside groove;
Fig. 2 is that the utility model is for processing the top view of the drum cutter of housing inside groove;
Fig. 3 is the zoomed-in view in I portion in Fig. 1.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments, when not conflicting, the embodiment in the application and the feature in embodiment can combine mutually, below with reference to the accompanying drawings and describe the utility model in detail in conjunction with the embodiments.
Refer to shown in Fig. 1, a kind of drum cutter for processing housing inside groove, comprise cutter hub 10 and knife bar 20, knife bar 20 is installed on the axial line in the middle part of cutter hub 10.
Consult Fig. 3, cutter hub 10 comprises the lower end 12 of upper end 11 in drum organization and cylindrical-shaped structure, particularly, the upper end 11 of cutter hub 10 for radius be the drum organization that the arcwall face of 3.75mm and the top and bottom of upper end 11 intersect formation, the lower end 12 of cutter hub 10 for diameter be the column structure of 2.65mm.
Further, the lower end 12 of cutter hub 10 forms escape groove 121, the degree of depth of escape groove 121 is 1mm, the upper end 11 of cutter hub 10 offers the edge of a knife about the axial line of cutter hub 10 outside cutter hub 10, in conjunction with consulting Fig. 2, the edge of a knife being connected with diamond 13 and forming blade, particularly, diamond 13 is welded on the edge of a knife, and in order to process channel profiles in processing mobile phone housing or electronic product casing, the outer face of diamond 13 is higher than the outer face of cutter hub 10.
Adopt adamantine benefit: 1. adamantine hardness can reach 8000HV, be 8-12 times of carbide alloy;
2. adamantine thermal conductivity factor is 700W/mK, and be 1.5-9 times of carbide alloy, even higher than PCBN and copper, therefore the transmission of diamond cutter heat is rapid;
3. adamantine coefficient of friction is generally only 0.1-0.3 (coefficient of friction of carbide alloy is 0.4-1), and therefore diamond cutter significantly can reduce cutting force;
4. adamantine thermal coefficient of expansion is only 0.9 × 10
-6-1.18 × 10
-6, be only equivalent to 1/5 of carbide alloy, therefore diamond cutter thermal deformation is little, and machining accuracy is high;
5. diamond cutter and the affinity between non-ferrous metal and nonmetallic materials very little, in process, chip does not form built-up edge on point of a knife.
Knife bar 20 is installed on the axial line in the middle part of cutter hub 10, and knife bar 20 adopts wolfram steel to make, and the hardness of wolfram steel can reach 89-95HRA, not easy to wear, intensity and good toughness, consult Fig. 1 again, and knife bar 20 comprises the top 21 of round table-like structure and the bottom 22 of cylindrical-shaped structure.
The length of knife bar 20 is 45mm, the bottom 22 of knife bar 20 for diameter be the cylinder of 6mm, the bottom of bottom 22 offers the chamfering of 1mm × 45 degree.
In sum, the utility model forms blade for the drum cutter processing housing inside groove by offering the edge of a knife and weld diamond on cutter hub on the edge of a knife, during the interior channel profiles of processing mobile phone housing or electronic product casing, without the need to carrying out tool changing processing, operating efficiency is high, secondly, edge wear is little, stability is strong, the machining accuracy of interior channel profiles is high, and this is for processing the drum cutter delicate structure of housing inside groove, saves material.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
