Summary of the invention
The technical problem that the present invention will solve just is: to the technical problem that prior art exists, the present invention provide a kind of simple and compact for structure, process and make drill bit die for processing simple, with low cost, easy and simple to handle, good forming effect.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of drill bit die for processing; It is characterized in that: comprise the concentric ring that saw-tooth ring and more than one break-out material are processed; Said saw-tooth ring is provided with the moulding that is used for that along the circumferential direction is arranged in order more than two and bores the teeth groove of tooth; Said saw-tooth ring offers more than one annulus hole successively along radial direction, and said concentric ring is inserted in the annulus hole at equivalent diameter place.
As further improvement of the present invention:
The thickness that is positioned at teeth groove opening part one end on the said concentric ring is greater than the other end.
Compared with prior art, the invention has the advantages that:
1, drill bit die for processing of the present invention; Adopt fabricated structure; Be prepared from different materials respectively, it is simple and compact for structure, it is simple, with low cost, easy and simple to handle to process and make, and can guarantee to form many circles and bore teeth; And separate through concentric ring easy to wear, final in use formation automatically separated the groove that bores tooth;
2, drill bit die for processing of the present invention is because the thickness that is positioned at teeth groove opening part one end on the concentric ring is greater than the other end.Therefore, the drill bit upper groove of processing and fabricating is opening-like, and the width that is positioned at the openend that bores tooth on the groove is greater than being positioned at a stiff end that bores tooth root portion.Can let the brill tooth remain so on the one hand and be wedge shape, more effectively fractured rock; On the other hand, the groove of big open-type is easy to out bits, and rock grain or sillar are difficult in groove, being stuck, and very easily come off along with the vibration of drill bit even block also once in a while, thereby are difficult for bit freezing.For complicated landforms, the more traditional sawtooth of adaptability has had further lifting.

The specific embodiment
Below will combine Figure of description and specific embodiment that the present invention is explained further details.
Like Fig. 1, Fig. 2, Fig. 3 and shown in Figure 4, a kind of drill bit die for processing of the present invention comprises the concentric rings that saw-tooth ring 1 and more than one break-out material are processed, and saw-tooth ring 1 is a hollow form, and is processed by rigid material.Bore the teeth groove 7 of tooth 5 being provided with the moulding that is used for that along the circumferential direction is arranged in order more than two on the saw-tooth ring 1, saw-tooth ring 1 offers the annulus hole 3 of more than one arranged concentric successively along radial direction, and concentric rings is inserted in the annulus hole 3 at equivalent diameter place.In preferred embodiment, the thickness that is positioned at teeth groove 7 opening parts one end on the concentric rings is greater than the other end.
Alloy material or diamond composite material are placed mould of the present invention, and after forming drill bit under certain processing conditions, the demoulding is taken out.This manufacturing process is the conventional means that drill bit is made, and just repeats no more at this.Referring to shown in Figure 5, adopt the formed in mould drill bit of the present invention, it comprises drill body 4, the working face of drill body 4 is provided with a plurality of brill teeth 5 that formed by teeth groove 7.The design of this brill tooth 5, non-slip and timeliness is very fast in the time of can guaranteeing that it creeps into the ultrahard stratum.On this drill bit,, separate through concentric rings because therefore the existence of concentric rings has been arranged in order the radial direction of a plurality of brill teeth 5 along drill body 4 into more than two circles.And in actual use,, so can form groove 6 gradually between the two adjacent rings brill tooth 5 owing to concentric rings is made by break-out material.The design that this many circles bore tooth 5 can guarantee that the drill bit work limitation is very fast, the life-span is longer.Design through groove 6; Not only can guarantee to bore tooth 5 radial direction segmentation along drill body 4 when work; Can also let and bore tooth 5 (circumferentially) segmentation along the circumferential direction, (for example: contact area rock) becomes and reduces, and improves unit the pressure of the drill with treating drilling area thereby make brill tooth 5.In whole drilling process, groove 6 can keep the shape of bit face teeth groove always, through boring the rotation or the vibration of tooth 5, can form volumetric fracture effectively with snapping in groove 6 interior scars, makes the avalanche of sillar bulk.The design of groove 6 can make the rock at groove 6 places be given a shock, shear, push, and produces micro-crack, thereby obtains volumetric fracture automatically, thereby can improve drilling efficiency and bit life by a relatively large margin; Simultaneously, can also make whole drill bit and treat that the contact point of drilling area increases, can not only keep the high speed of creeping into to hard, ultrahard stratum, and can keep the integrality of core, guarantee hole quality.
Because the thickness that is positioned at teeth groove 7 opening parts one end on the concentric rings is greater than the other end.Therefore, in the present embodiment, groove 6 is opening-like, and the width that is positioned at the openend that bores tooth 5 tops on the groove 6 is greater than being positioned at a stiff end (for example being V-type) that bores tooth 5 roots.Can let brill tooth 5 remain so on the one hand and be wedge shape, more effectively fractured rock; On the other hand, the groove 6 of big open-type is easy to out bits, and rock grain or sillar are difficult in groove 6, being stuck, and very easily come off along with the vibration of drill bit even block also once in a while, thereby are difficult for bit freezing.For complicated landforms, the more traditional sawtooth of adaptability has had further lifting.
Below only be preferred implementation of the present invention, protection scope of the present invention also not only is confined to the foregoing description, and all technical schemes that belongs under the thinking of the present invention all belong to protection scope of the present invention.Should be pointed out that for those skilled in the art some improvement and retouching not breaking away under the principle of the invention prerequisite should be regarded as protection scope of the present invention.
