The specific embodiment
Below with reference to Figure of description and specific embodiment the present invention is described in further details.
As shown in Figure 1, Figure 2, Figure 3 and 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 made, and saw-tooth ring 1 is a hollow form, and is made 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 by 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 multi-turn is bored tooth 5 can guarantee that the drill bit work limitation is very fast, the life-span is longer.Design by groove 6, not only can guarantee to bore tooth 5 radial direction segmentation along drill body 4 when work, can also allow 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, by 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.
Owing to be positioned at the thickness of teeth groove 7 opening parts one end greater than the other end on the concentric rings.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 allow 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 for being stuck in groove 6, 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 the some improvements and modifications not breaking away under the principle of the invention prerequisite should be considered as protection scope of the present invention.
