Abstract
The invention relates to a rock-drilling drill bit spherical tooth, which belongs to a drill bit device. The rock-drilling drill bit spherical tooth comprises a hard alloy spherical tooth body, wherein the inside of the hard alloy spherical tooth body is provided with a blind hole, and the inside of the blind hole is provided with a spherical tooth supporting steel body. On the premise that the use performance of the drill bit spherical tooth is guaranteed, the valuable material of the rock-drilling drill bit spherical tooth can be effectively saved, and the production cost of a down-the-hole drill bit is lowered.
Description
Technical field
The present invention relates to drill bit device, particularly can effectively save the precious materials of rock drill head shoot tooth, the rock drill that reduces production costs head shoot tooth.
Background technology
Used rock drill head shoot tooth all is integrative-structure in producing in geological prospecting, mine, and in use hard rock is very serious to the wearing and tearing of drill bit ball tooth.When using a period of time, after the hard alloy spherical-teeth of chisel edge was worn down to a certain degree, drill bit ball tooth just can not continue to use, the drill bit that must more renew, the whole drill bit that can not continue to use is used as waste disposal, causes very large waste, improved brill rock cost.
Summary of the invention
The purpose of this invention is to provide a kind of precious materials of saving rock drill head shoot tooth, the rock drill that reduces production costs head shoot toothing.
Technical solution of the present invention is that rock drill head shoot tooth comprises the hard alloy spherical-teeth main body, is provided with blind hole in described hard alloy spherical-teeth main body, is provided with ball tooth supporting steel body in described blind hole.
The diameter of the blind hole in the above-described hard alloy spherical-teeth main body and the degree of depth can be Φ 6 ~ Φ 10 mm * 20 ~ 26mm.
Blind hole in the hard alloy spherical-teeth main body of the present invention can be preformed in the SINTERING PRODUCTION of hard alloy spherical-teeth main body, or technique by the punching of laser, electric pulse obtains.
Ball tooth supporting steel body of the present invention can be that the mode by casting fills in the blind hole in the hard alloy spherical-teeth main body.
Ball tooth supporting steel body of the present invention can be inlayed in blind hole by interference fit.
Ball tooth supporting steel body of the present invention can adopt the organic or inorganic cementing agent to be bonded in the blind hole.
Ball tooth supporting steel body of the present invention can be that the Inlaid system is therebetween in hard alloy spherical-teeth main body sintering process.
Advantage of the present invention is the precious materials that can effectively save rock drill head shoot tooth under the prerequisite of the functional performance that guarantees drill bit ball tooth, reduces the cost of production of hidden hole drilling drill bit.
Description of drawings
Fig. 1 is organigram of the present invention;
Fig. 2 is along the A-A sectional view among Fig. 1.
The specific embodiment
As shown in Figure 1 and Figure 2, the outside of rock drill head shoot tooth of the present invention is hard alloy spherical-teeth main body 1, is processed with blind hole in described hard alloy spherical-teeth main body 1, has filled high speed steel ball tooth supporting steel body 2 in described blind hole.
The diameter of hard alloy spherical-teeth main body 1 of the present invention is Φ 18 mm, and its length is 30 mm.The depth dimensions of the blind hole in the hard alloy spherical-teeth main body 1 is 26 mm, also can select in 20 ~ 26 mm scopes.The diameter dimension of blind hole is Φ 10 mm, also can select in Φ 6 ~ Φ 10mm scope.
Blind hole in the described hard alloy spherical-teeth main body 1 is to burn in advance to separate to form in the manufacturing process of hard alloy spherical-teeth main body 1, also can obtain by the technique of laser, electric pulse punching.
Described high speed steel ball tooth supporting steel body 2 is that the mode by casting fills in the blind hole in hard alloy spherical-teeth main body 1.
Described high speed steel ball tooth supporting steel body 2 can be inlayed in blind hole by interference fit.
Described high speed steel ball tooth supporting steel body 2 can adopt organic binder such as agricultural machinery adhesive to be bonded in the blind hole, and also available inorganic binder is bonded in the blind hole such as 502 cementing agents.
After described high speed steel ball tooth supporting steel body 2 also can be first prepares by the diameter dimension of the blind hole in the hard alloy spherical-teeth main body 1, the Inlaid system was therebetween in hard alloy spherical-teeth main body 1 sintering process again.
