Abstract
The utility model discloses a drilling tool for punching. The drilling tool comprises a metal cylindrical basal body, a cutting tool bit and an alloy threaded drill, wherein the cross section of the cutting tool bit is in the shape of a ring and fixed on the lower end surface of the metal cylindrical basal body, the alloy threaded drill is arranged in an inner chamber of a round cylinder of the metal cylindrical basal body, a cylindrical boss is fixed on the upper end surface of a threaded part, and a through hole and steps are arranged on the cylindrical boss. A hole can be stably drilled, so that the quality of the inner wall of the hole is ensured. The drilling tool with longer service life can determine the size of the metal basal body according to the size of the hole, and the drilling tool and a material core can be taken out conveniently after the cutting is completed due to the arrangement of a drilling rod, so that the work efficiency is improved.
Description
Technical field
The utility model relates to a kind of Hole drilling set.
Background technology
The general electric perforator that uses is equipped with grooved bit at the puncher front end in daily life and the engineering, and the grooved bit front end is welded with carbide alloy usually, smashes the purpose of material to reach cutting.The diamond Hole drilling set comes cutting material by the diamantiferous drill bit of grooved bit front end, and at present, the defective of alloy drilling tool and diamond Hole drilling set is:
1, alloy drilling tool diameter is all less, and general diameter is 12mm～60mm, and drill body exists internal stress to concentrate and microfissure in manufacturing process, when impacting above a certain value, drill body can fracture or collapse broken, and the diameter of grooved bit is big more, and the possibility that this problem occurs can be big more.
2, the alloy drilling tool generally can not one-shot forming to the very big hole of diameter, and will finish by punching repeatedly, and the punching effect is relatively poor.
3, reinforcing bar or stone take place easily and are stuck in situation between material core and the drilling tool inwall in diamond drill when drill steel reinforced concrete and similar material, and pressure is taken off and can be caused drill pipe deformations, not only influences service life but also reduced operating efficiency.
Summary of the invention
The purpose of this utility model is in order to overcome above-mentioned the deficiencies in the prior art, a kind of diamond grooved bit that core is easy, the perforate scope is wide and punch effective of getting to be provided.
The technical solution adopted in the utility model is: comprise metallic cylinder matrix, cutter tip and alloy screw thread drill bit, the cross section of cutter tip is circular and is fixed on the lower surface of metallic cylinder matrix, alloy screw thread drill bit is arranged in the cylinder bore of metallic cylinder matrix and its upper end connecting thread parts, fixed cylinder boss on the upper surface of screwed part, cylinder boss is provided with through hole and step.
The beneficial effects of the utility model are:
1, contain the diamond composition in the cutter tip, sharper, and adopted circular design, relatively steadily, can guarantee the quality of hole inwall in the boring procedure.
2, the life-span of drilling tool longer, when cutter tip hinders for some reason and comes off or use when grind to the greatest extent because of long-term, standby cutter tip can be welded in continuation use on the metallic matrix.
3, can determine the size of metallic matrix according to the size in hole,, metallic matrix be made corresponding diameter and be got final product if bore the drilling tool of macropore.
4, the installation of drilling rod can be taken out drilling tool and material core after cutting finishes easily, has improved operating efficiency.
5, when materials such as cutting armored concrete, the steel bar end that exposes can forward the strip hollow out place of metallic matrix side to, is aided with other apparatus then it is taken out.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 looks outline drawing for master of the present utility model.
Fig. 2 looks cutaway view for master of the present utility model.
Fig. 3 is the vertical view of Fig. 1.
Among the figure: 1. metallic cylinder matrix; 2. strip hollow out; 3. cutter tip; 4. alloy screw thread drill bit; 5. screwed part; 6. through hole; 7. cylinder boss; 8. step.
The specific embodiment
As Figure 1-3, Hole drilling set is made up of three parts: metallic cylinder matrix 1, cutter tip 3 and alloy screw thread drill bit 4.Metallic cylinder matrix 1 can be made by cast iron or other metals, cutter tip 3 mixes sinter molding by diamond particles and some other metal powder in certain ratio, the cross section of cutter tip 3 is circular and is fixedly welded on the lower surface of metallic cylinder matrix 1, its circular arc outline overlaps with the outline of metallic cylinder matrix 1, and the thickness of cutter tip 3 is identical with the barrel thickness of metallic cylinder matrix 1.
Alloy screw thread drill bit 4 is arranged in the cylinder bore of metallic cylinder matrix 1 and its upper end connecting thread parts 5, and fixed cylinder boss 7 on the upper surface of screwed part 5, cylinder boss 7 are provided with through hole 6 and step 8, and step 8 is respectively established one in the both sides of screwed part 5.
Several strip hollow outs 2 are set on the cylindrical wall of metallic cylinder matrix 1 communicate with cylinder bore, its effect has 2 points: the one, in boring procedure, store a part of chip, in order to avoid chip too destroys the inner surface in hole; The 2nd, when boring finished to get core, the effect of expansion space can be played by strip hollow out 2 places, helps getting core.
In use, screw in alloy screw thread drill bit 4 earlier in screwed part 5, the connecting thread of drilling rod and metallic matrix top cylinder boss 7 expose outside metallic cylinder matrix 1, and then are connected with electric perforator.During rotation, on material, hole in the time of alloy screw thread drill bit 4 cutting materials.When treating that rotation finishes, electric perforator and grooved bit are separated, pass the through hole 6 on top, alloy screw thread drill bit 4 is screwed out together with the material core that cuts, fix the material core then, alloy screw thread drill bit 4 is screwed out from expect core with a metallic rod.
