Description
Technical field
The utility model belongs to cutting-tool engineering field, is related to a kind of cutter for machining more particularly to a kind of use
In the chit drill of processing copper workpieces.
Background technique
Currently, generally processing the deep hole of copper workpieces using chit drill, deep hole such as is processed on copper valve body.Using biography
During the chit drill of system is processed, since operator can not observe the working condition of chit drill, easily there is cutting heat in when processing
The phenomenon that excessively concentrating and burning knife.It is usually integral structure there are also traditional chit drill, entire chit drill is manufactured using hard alloy
It forms, whole manufacturing cost is higher.Therefore, it is necessary to design a kind of chit drill, to solve the above technical problems.
Utility model content
The chit drill that the purpose of the utility model is to provide a kind of heat dissipation performances is superior, manufacturing cost is low.
In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model is: one kind is for processing copper workpieces
Chit drill, including knife handle and flat cutter hub, one end of the knife handle is equipped with semicircular mounting groove, one end of the cutter hub
Equipped with semicircular fixed part, the fixed part and the mounting groove cooperate, and the fixed part is welded to each other with the knife handle, institute
Cutter hub is stated equipped with cutting portion, one end of the cutting portion is equipped with apex point, and the cutting portion is equipped with blade, the cutting portion
Two sides are respectively equipped with two convex ribs being parallel to each other, and are equipped with through slot on the cutter hub between two convex ribs, described
Through slot penetrates through on the thickness direction of the cutter hub.
Further, the cross section semicircular in shape or rectangle of the convex ribs.
Further, the both ends of the convex ribs are equipped with inclined-plane.
The utility model is the utility model has the advantages that the chit drill of the utility model increases in the case where not influencing chip removal and cutter hub intensity
The strong heat dissipation performance of cutter hub, therefore the heat dissipation effect of the chit drill is very good prevents from heat occur when processing excessively to concentrate
The phenomenon that now burning knife；The chit drill is fabricated structure, and cutter hub is fabricated using the relatively high hard alloy of price, and knife handle is adopted
It is fabricated with the lower high-speed steel of price, to reduce the whole manufacturing cost of cutter.

Specific embodiment
Below in conjunction with the attached drawing of the utility model, the technical scheme in the embodiment of the utility model is carried out clear, complete
Site preparation description, it is clear that the described embodiments are only a part of the embodiments of the utility model, instead of all the embodiments.
Based on the embodiments of the present invention, obtained by those of ordinary skill in the art without making creative efforts
Every other embodiment, fall within the protection scope of the utility model.
As depicted in figs. 1 and 2, the chit drill for being used to process copper workpieces of the present embodiment.The chit drill includes knife handle 1 and flat
The cutter hub 2 of shape, the making material of knife handle 1 are high-speed steel, and the making material of cutter hub 2 is hard alloy.
Referring to Fig. 3 and Fig. 4, the upper end of knife handle 1 is machined with a semicircular mounting groove 11.Referring to figure 5 and figure 6, cutter hub 2
Lower end be machined with semicircular fixed part 21, fixed part 21 and mounting groove 11 cooperate, and fixed part 21 is welded to each other with knife handle 1,
To which cutter hub 2 is fixed on knife handle 1.Cutting portion 22 is machined on cutter hub 2, the upper end of cutting portion 22 is machined with apex point 24, cuts
Cut in portion 22 processing blade 221, the two sides of cutting portion 22 are machined with two convex ribs being parallel to each other 23 respectively, convex ribs 23 it is transversal
Face is rectangle, and the both ends of convex ribs 23 are machined with inclined-plane respectively, is machined with one for radiating between two convex ribs 23 on cutter hub 2
Through slot 25, through slot 25 penetrates through on the thickness direction of cutter hub 2.
The chit drill of the utility model, cutter hub are equipped with convex ribs and through slot for heat dissipation, dissipate in convex ribs and the dual of through slot
Under heat effect, improve the heat dissipation effect of cutter hub, prevent processing when occur heat excessively concentrate and occur burn knife the phenomenon that；Two
Convex ribs are arranged parallel, and through slot is set between two convex ribs, in the premise of the intensity for the smooth and cutter hub that ensure that chip removal
Under, and enhance heat dissipation effect；The chit drill is fabricated structure, and cutter hub is manufactured using the relatively high hard alloy of price, and knife
Handle uses the lower high speed steel making of price, to reduce the whole manufacturing cost of cutter.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection scope within.
