Abstract
The utility model relates to a novel composite geological drill bit. The novel composite geological drill bit comprises diamond compacts, electroplated diamond layers, metal steel bodies, electroplated diamond cylinders and glomerocryst gauge protection bars. The diamond compacts are compacts used for a traditional compact bit. The novel composite geological drill bit is characterized in that each metal steel body is formed in the manner that the rear support portion of each steel body of the traditional compact bit is lengthened to form a plane, the glomerocryst gauge protection bars are brazed on the rear support portions respectively, the diamond compacts are welded on the rear support portions respectively in a silver soldering mode, each electroplated diamond layer is plated on the rear support portion and the side face of each diamond compact in a low-temperature electroplating mode, and then a diamond drill bit and the compact bit are integrated. The novel composite geological drill bit has the advantages of being capable of ensuring the efficient cutting function of the diamond compacts and the efficient grinding function of the diamond drill bit. The stratum application range of the novel composite geological drill bit is expanded.
Description
Technical field
The utility model relates to a kind of drill bit, is specifically related to a kind of NEW TYPE OF COMPOSITE geological drill bit.
Background technology
Diamond core bit is a kind of common boring tool, at present, and the extensive use in geological exploration mine locating of common compact bit and diamond bit.The advantage of compact bit high-efficient cutting, but applicable geology scope take compared with soft formation as main, for example coal seam; The high abrasion function of diamond bit, can creep into complete hard rock stratum, for example granite.Current composite sheet geological drill bit, the stratum scope of adaptation is not wide, and in coal seam, scall is effective, but just cannot creep on hard stratum; Diamond bit is but good in hard stratum result of use, and but drilling efficiency is low.
Summary of the invention
The deficiency that the purpose of this utility model exists in order to overcome above-mentioned prior art, a kind of composite sheet, diamond bit combined bits are provided, this drill bit not only has compact bit high-efficient cutting advantage, has again diamond bit high abrasion grinding advantage simultaneously, has expanded the stratum scope of application.
The concrete technical scheme of the utility model is:
A kind of NEW TYPE OF COMPOSITE geological drill bit, comprise diamond compact, electroplated diamond layer, metallic steel body, electroplated diamond cylinder, glomerocryst gauge bar, described diamond compact is traditional compact bit composite sheet used, described metallic steel body is that every place rear support part on traditional compact bit steel body is lengthened, form a plane, stay and electroplate space, brazing glomerocryst gauge bar in every place rear support part, silver soldering diamond compact in every place rear support part, complete after diamond compact welding, use again the mode of cold galvanising, plate electroplated diamond layer in each diamond compact rear support part and side, form diamond bit and compact bit integrated.Described electroplated diamond layer is the electroplated diamond cylinder of implanting moulding in advance, seals the region of non-plating, carries out cold galvanising moulding.
Effect of the present utility model is, both guaranteed the high cutting function of composite sheet, the combined bits of the high grinding function of guarantee fund's hard rock again, and this drill bit has expanded the stratum scope of application.
Accompanying drawing explanation
Fig. 1 is organigram of the present utility model.
Fig. 2 is the I-I sectional view of Fig. 1.
The specific embodiment
The utility model will be further described by reference to the accompanying drawings.
As shown in Figure 1 and Figure 2, the utility model comprises diamond compact 1, electroplated diamond layer 2, metallic steel body 3, electroplated diamond cylinder 4, glomerocryst gauge bar 5.Described diamond compact 2 is traditional compact bit composite sheet used, described metallic steel body 3 is that every place rear support part on traditional compact bit steel body is lengthened, form a plane, stay and electroplate space, in every place rear support part, press traditional handicraft brazing glomerocryst gauge bar 5, silver soldering diamond compact 1 in every place rear support part, complete after diamond compact 1 welding, use again the mode of cold galvanising, plate electroplated diamond layer 2 in each composite sheet rear support part and side, form diamond bit and compact bit integrated.Described electroplated diamond layer 2 is electroplated diamond cylinders 4 of implanting moulding in advance, seals the region of non-plating, carries out cold galvanising moulding.
Claims (2)
1. a NEW TYPE OF COMPOSITE geological drill bit, comprise diamond compact, electroplated diamond layer, metallic steel body, electroplated diamond cylinder, glomerocryst gauge bar, described diamond compact is traditional compact bit composite sheet used, it is characterized in that: described metallic steel body is on traditional compact bit steel body, to lengthen in every place rear support part, form a plane, brazing glomerocryst gauge bar in every place rear support part, silver soldering diamond compact in every place rear support part, plate electroplated diamond layer by the mode of cold galvanising in each diamond compact rear support part and side again, form diamond bit and compact bit integrated.
