Technical field
The utility model relates to a kind of moulding and bores, and relates in particular to a kind of for processing the composite molding brill of the reverse chamfering of aluminium class part.
Background technology
Forming drill, as an important component part in cutter for machining, is mainly used in the processing in hole.In recent years, along with the development of machinery industry, user all had higher requirement to production cycle of the crudy of product, process reliability, working (machining) efficiency, cutter etc.Yet, traditional forming drill in use, can only complete the processing of positive face and the processing of positive surface chamfer, and cannot complete the processing of reverse chamfering, for example: as shown in Figure 1, forming drill 2 only can complete the processing of positive face and the processing of positive surface chamfer on aluminium class part 1, and the aluminium class part 1 after completion of processing has hole 3 and positive surface chamfer 5 as shown in Figure 2; Then, need by reverse molding as shown in Figure 3, bore 4 again and on aluminium class part 1, complete the processing of reverse chamfering, the aluminium class part 1 after completion of processing except having hole 3 and positive surface chamfer 5, also has reverse side chamfering 7 as shown in Figure 4.
In sum, while completing hole, positive surface chamfer and reverse side chamfering on aluminium class part, need to complete by two cutters, so not only increase technique, also increase the use cost of cutter, thereby made the manufacturing cost of aluminium class part higher.
Utility model content
Technical problem to be solved in the utility model is to provide lower the boring for processing the composite molding of the reverse chamfering of aluminium class part of a kind of use cost.
For solving the problems of the technologies described above, the utility model provides a kind of and bores for processing the composite molding of the reverse chamfering of aluminium class part, comprise drill body, on described drill body, there is bore portion for holing and for carry out the upper chamfered section of chamfering on top, hole, the top of described bore portion has for carry out the lower chamfered section of chamfering in bottom, hole, described bore portion is connected by connecting portion with described upper chamfered section, and the diameter of described connecting portion is less than the diameter of described bore portion.
Described connecting portion comprises connecting portion epimere and connecting portion hypomere, and described connecting portion epimere and described connecting portion hypomere removably connect.
The bottom face center of described connecting portion epimere is inwardly formed with screwed hole along its axis, and the top end face center of described connecting portion hypomere is provided with the screw rod matching with described screwed hole along its axis.
On the knife face of described bore portion, be provided with a plurality of apopores, described apopore communicates with the cooling-water duct of described drill body inside.
Compared with prior art, the beneficial effects of the utility model are: due to the utility model on drill body, have bore portion, on chamfered section and lower chamfered section, thereby using one cutter in the situation that, just can complete boring, upper chamfering and lower chamfering, so not only saved the time of changing cutter, also reduced technique, so the utility model use cost is lower.

Wherein: aluminium class part 1, hole 3, drill body 10, bore portion 12, upper chamfered section 14, lower chamfered section 16, connecting portion epimere 15, connecting portion hypomere 18, screwed hole 20, screw rod 22, apopore 24, cooling-water duct 26.
The specific embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and embodiments, the utility model is described in further details.At this, exemplary embodiment of the present utility model and explanation are used for explaining the utility model, but not as to restriction of the present utility model.
Shown in Figure 5, of the present utility model a kind of for processing the composite molding brill of the reverse chamfering of aluminium class part, comprise drill body 10, on this drill body 10, there is bore portion 12 for holing and for carry out the upper chamfered section 14 of chamfering on top, hole, this bore portion 12 and upper chamfered section 14 can be planforms well known by persons skilled in the art, as long as it can complete boring and chamfering, special support of the present utility model is: on the top of bore portion 12, have for carry out the lower chamfered section 16 of chamfering in bottom, hole, the mirror-image structure that Gai Xiadao foot 16 is upper chamfered section 14 has cutting blade on it, in addition, bore portion 12 is connected by connecting portion 13 with upper chamfered section 14, the diameter of this connecting portion 13 is less than the diameter of bore portion 12, during use, as shown in Figure 6, bore portion 12 completes the processing in hole 3 first straight down on aluminium class part 1, and then continue by upper chamfered section 14, on the top in hole 3, to complete chamfering downwards, afterwards as shown in Figure 7, to hole, 3 inwall moves the central axis of drill body 10 offset bores 3, blade in lower chamfered section 16 contacts with aluminium class part 1, in hole, 3 bottom completes chamfering, in this process, boring, upper chamfering and lower chamfering are all to adopt one cutter is completed, therefore, do not need to change cutter, thereby saved the time of changing cutter, reduced technique, reduced production cost.
In addition, connecting portion 13 comprises connecting portion epimere 15 and connecting portion hypomere 18, bore portion 12 is arranged on connecting portion hypomere 18, and upper chamfered section 14 is arranged on connecting portion epimere 15, connecting portion epimere 15 and connecting portion hypomere 18 removably connect, concrete is along its axis, inwardly to form screwed hole 20 in the bottom face center of connecting portion epimere 15, top end face center at connecting portion hypomere 18 is provided with the screw rod 22 matching with screwed hole 20 along its axis, due to bore portion 12, wearing and tearing are very fast conventionally, can be in 14 one of them wearing and tearing of bore portion 12 and upper chamfered section when more serious by this structural design, only need to change one, thereby can further reduce the cost that cutter uses.
Finally, in process, for making cutter, can lower the temperature fast by cooling water, on the knife face of bore portion 12, be provided with a plurality of apopores 24, this apopore 24 communicates with the cooling-water duct 26 of drill body 10 inside, and it is large that the aperture of apopore 24 becomes from inside to outside gradually, so not only can increase the circulation rate of cooling water, can also increase the area of heat transfer of cutter and cooling water, thereby further reach the object of fast cooling.
In use, because the top standing part of drill body 10 is cylindrical shape, its clamping and fixing more difficult, can occur to swing frequently, therefore, the utility model is provided with projection 101 the interval, top of drill body 10, symmetrical and the vertical cross-section of these two projections 101 is right angled triangle, is also provided with in addition shrinkage pool 102, during use on the top of drill body 10, adopt the securing member coordinating with its shape to fix, just can well prevent that drill body 10 from swinging.
