Abstract
The utility model discloses an improved type diamond bit which comprises a bit body. An annular work layer is arranged on the lower portion of the bit body and of a bronze binding agent diamond layer, the thickness of the diamond layer is approximately 0.7mm, and a water-through chip removal open groove is formed in the bottom end of the work layer. Through improvement, the improved type diamond bit improves drilling efficiency of the bit, and reduces drilling resistance and heat generated in drilling friction.
Description
Technical field
The utility model relates to drill bit, relates in particular to a kind of improved diamond drill bit.
Background technology
Diamond bit is mainly used in punching on the hard articles such as pottery, glass, the case hardness of these article is higher, adopt common steel drill bit to punch normally, due to diamond bit hardness ratio pottery and glass high, so can punch on these hard articles.Existing pottery, glass are the bronze binding agent diamond layer with the working lining under the diamond bit matrix, and this diamond layer just need to put the first edge on a knife or a pair of scissors after existing and beating a period of time again, and stock-removing efficiency is lower, and the reason that causes specifically has 2 points: 1, the working lining wall is too thick; 2, do not carry out intake chamber processing.
The utility model content
The purpose of this utility model is the problem of mentioning in the above-mentioned background technology in order to solve, and a kind of improved diamond drill bit is provided.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of improved diamond drill bit, comprise bit matrix, described drill body bottom is provided with the annular working layer, and described working lining is the bronze binding agent diamond layer, the thickness of described diamond layer is the 0.7mm left and right, and described working lining bottom also is provided with water flowing chip removal fluting.
Further, described working lining bottom is distributed with 3-7 water flowing chip removal fluting.
Further, the degree of depth of described water flowing chip removal fluting is the 3mm left and right.
Further, the width of described water flowing chip removal fluting is the 1mm left and right.
Compared with prior art, the beneficial effects of the utility model are as follows:
1, stock-removing efficiency is improved significantly, the diamond bit that arranges in the utility model, and its bronze binding agent diamond layer is the 0.7mm left and right by existing 1mm improvement, put the first edge on a knife or a pair of scissors easily, and stock-removing efficiency has improved about 30 percent left and right.
2, the utility model offers several water flowing excretion flutings in the working lining bottom, makes the break flour of drilling drill bit operative end surface and the break flour of rapidoprint gap part drain more smoothly, has reduced and has crept into resistance and fricative heat.
Description of drawings
In order to be illustrated more clearly in the technical scheme of the utility model embodiment, in below describing embodiment, the accompanying drawing of required use is briefly described, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation in the present embodiment;
Fig. 2 is the profile of A-A;
Reference numeral: 1-bit matrix; The 2-diamond layer; 3-water flowing chip removal fluting.
The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making under the creative work prerequisite the every other embodiment that obtains, and all belong to the scope of the utility model protection.
In conjunction with a kind of improved diamond drill bit shown in Fig. 1,2, comprise bit matrix 1, its bit matrix 1 bottom is provided with the annular working layer, its working lining is bronze binding agent diamond layer 2, the thickness of its diamond layer 2 is the 0.7mm left and right, and its working lining bottom also is provided with water flowing chip removal fluting 3.
In the present embodiment, the thickness of its bronze binding agent diamond layer 2 is 0.7mm by the 1mm fabrication design of prior art, makes in driller's work, has reduced its number of times that puts the first edge on a knife or a pair of scissors, and stock-removing efficiency has improved about 30 percent left and right, thereby improved diamond drill bit practicality is stronger.
In the present embodiment, its working lining end face is distributed with 3-7 water flowing chip removal fluting 3, be used for reducing the break flour of drilling drill bit operative end surface and the friction between rapidoprint, thereby reduced the burr phenomenon of glass processing, the setting of its water flowing chip removal fluting 3 in addition, be conducive to the injection of cooling fluid, reduced rapidoprint and can not get because of the drilling regional temperature rapidoprint distortion or the burn phenomenon that in time cooling brings.
In the present embodiment, the degree of depth of its water flowing chip removal fluting 3 is the 3mm left and right, and width is the 1mm left and right.
The foregoing is only preferred embodiment of the present utility model,, not in order to limit the utility model, all any modifications of doing, be equal to replacement etc., within all should being included in protection domain of the present utility model in protection domain of the present utility model.
