Abstract
The utility model provides a unified diamond thin wall drill, composed of a taper threaded joint, a drill body and an annular drill teeth. The annular drill teeth is provided with a sawtooth skew water outlet groove, the block phenomenon is avoided appearing in the drilling progress, the strength of the drill is raised, the penetration speed is accelerated, and the service life is extended. The utility model is widely suitable for the pipe installation in construction work and the wall drilling in municipal construction and can also be provided for sampling for structure quality supervision units.
Description
The utility model relates to a kind of diamond bit, particularly a kind of monoblock type diamond thin-wall drill bit.It is widely used in that pipeline in the construction is installed and urban construction in wall boring, also can offer the usefulness of construction quality supervision unit sample.
At present, building trade and unit in charge of construction pipeline install and wall boring in, employed monoblock type diamond thin-wall drill bit all be by integral ring-shaped brill tooth around tying on drill body, its annular bit tooth has the right angle effluent trough.Because drill bit uses object mostly to be xoncrete structure (being made up of reinforcing bar, cement and stone), soft or hard degree difference is big, drill bit is easy to occur the jam phenomenon in drilling process, causing boring tooth comes off, cause heavy losses, Zuan Kong whole anti-torque is added in suddenly on one's body the operating personnel simultaneously, and accident easily meets accident.
The purpose of this utility model is to provide a kind of monoblock type diamond thin-wall drill bit, to solve the jam problem in the drilling process.
The utility model is achieved in that the utility model is connected in turn by tapering turnbuckle, drill body and annular bit tooth, has the oblique effluent trough of sawtooth on the annular bit tooth.
The utility model is used the oblique effluent trough of sawtooth, has increased the film-cooled heat of drill bit, and water outlet, chip removal are rapid, have accelerated penetration rate, has avoided the jam phenomenon that occurs in the drilling process, has improved the intensity of drill bit, has prolonged service life, has reduced contingency.
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1 is a structure chart of the present utility model;
Fig. 2 is a vertical view of the present utility model;
Fig. 3 is the profile of the utility model annular bit tooth 3.
Tapering turnbuckle 1 of the present utility model and drill body 2 fused by electric welding or brazing earlier, and again through machining, drill body 2 and annular bit tooth 3 are formed by connecting through high frequency brazing.Annular bit tooth 3 is by several specific metal powders and diamond batch mixing according to a certain percentage, then packing into, hot pressing forms in the whole ring-type graphite jig, oblique effluent trough 4 of its sawtooth and local tapering (section by one trapezoidal and rectangle form) are once finished in hot pressing, have solved the difficulty of processing tank after the moulding.
During use, tapering turnbuckle 1 is connected on the thin-walled rig, be communicated with water source, power supply, hole in clockwise manner, because drill body 2 lower ends are welded with certain wearability alloy and plate diamond drill machine tooth 3, it is circular that brill tooth 3 is shaped as the local tapering of whole thin-walled, and have an oblique effluent trough 4 of sawtooth, therefore not only in the drilling process water outlet fast, chip removal is rapid, solved the jam problem, prolonged service life, and it is rapid to get core, has improved operating efficiency, having reduced engineering cost, is comparatively desirable concrete boring instrument.
Claims (2)
1, a kind of monoblock type diamond thin-wall drill bit is connected in turn by tapering turnbuckle, drill body and annular bit tooth, it is characterized in that having the oblique effluent trough of sawtooth on the annular bit tooth.
2, monoblock type diamond thin-wall drill bit according to claim 1, the section that it is characterized in that the annular bit tooth by one trapezoidal and rectangle form.
