Detailed Description
The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings. It is to be understood that the description of the embodiments herein is for purposes of illustration and explanation only and is not intended to limit the invention.
Firstly, in order to facilitate understanding of the high-performance down-the-hole drill bit provided by the embodiment of the application, an application scenario of the high-performance down-the-hole drill bit is explained, and the high-performance down-the-hole drill bit provided by the embodiment of the application is used for underground drilling; when the down-the-hole drill bit in the prior art is used for high-abrasive rocks, the hard alloy column teeth of the down-the-hole drill bit are seriously worn or the hard alloy column teeth are early fallen off and broken. The high-performance down-the-hole drill bit provided by the embodiment of the application is described in the following with reference to the attached drawings.
The utility model provides a high performance down-the-hole drill bit, this high performance down-the-hole drill bit include a drill bit body 1, and this drill bit body 1 is used for connecting other parts in this application of installation.
Referring first to fig. 1, fig. 1 is a schematic structural diagram of a high-performance down-the-hole drill according to an embodiment of the present invention. As can be seen from fig. 1, the overall shape of the drill bit body 1 is trapezoidal, and a plurality of drill teeth 4 are fixedly arranged on the large surface of the drill bit body 1; when a plurality of drill teeth 4 are specifically arranged, 6 to 20 drill teeth 4, 6 in this case, may be uniformly arranged on the edge of the large face of the drill bit body 1, and 2 or 4 drill teeth 4, 2 in this case, may be uniformly arranged inside the large face of the drill bit body 1.
When the drill bit body 1 is manufactured, refer to fig. 2, and fig. 2 is a schematic structural diagram of a drill bit body of a high-performance down-the-hole drill bit according to an embodiment of the present invention. As can be seen from fig. 2, a plurality of mounting grooves 2 are uniformly formed on the large surface of the drill bit body 1; the mounting grooves 2 positioned at the edge of the large surface of the drill bit body 1 are obliquely arranged, and the oblique directions of the mounting grooves face the outer side of the drill bit body 1; the mounting grooves 2 positioned in the large surface of the drill bit body 1 are vertically formed; when the drill teeth 4 are installed in the installation groove 2, the drill bit body 1 is heated by laser quenching equipment, the drill teeth 4 are quickly and accurately placed in the installation groove 2 through a mechanical handle, and then the drill teeth 4 are fixed by utilizing the quick-heating and quick-cooling technical performance of the laser quenching equipment. Continuing to refer to fig. 2, the positions of the large surface of the drill bit body 1 except the mounting groove 2 are all covered with a layer of coating 3; when the coating 3 is specifically arranged, the coating 3 is composed of tungsten-titanium alloy powder, and when the coating 3 is covered, the tungsten-titanium alloy powder is rapidly melted and sprayed on the large surface of the drill bit body 1 except the mounting groove 2 by using laser cladding equipment. In the downward drilling process, the tungsten-titanium alloy has the characteristics of high hardness, wear resistance, good strength and toughness, heat resistance, corrosion resistance and the like, so that the coating 3 can achieve the purpose of protecting the drill bit body 1, thereby preventing the problems of tooth falling, tooth breakage and the like.
Continuing to refer to fig. 2, a main gas channel is arranged in the drill bit body 1, two sides of the main gas channel are respectively communicated with a sub gas channel, and one end of the sub gas channel far away from the main gas channel is arranged on the large surface of the drill bit body 1. When the pneumatic percussion drill is installed, the drill bit body 1 and the pneumatic percussion hammer are connected together, and the main gas channel is communicated with the interior of the pneumatic percussion hammer, so that the drill bit body 1 can drill downwards.
