Abstract
The utility model discloses an anti-stamping combined hole dilating drill bit for mines, wherein the front portion, the middle portion and the rear portion of a drilling base body are all provided with cutting edges, and the cutting edges are CWD coating alloy plates which are welded on the drilling base body, when a rear grade cutting edge is rotating, the diameter of cutting face which is formed is gradually bigger than the diameter of the cutting face which is formed when the front grade cutting edge is rotating, the tail portion of the drilling base body is a drilling handle, and the drilling base body is integrally hammered to shape. The drill bit is used for mines to drill holes under wells, which solves the problem that the original drilling hole with big diameter needs to change drill bits with different diameters, a hole can be formed through drilling in one time, working efficiency is greatly improved, and working intensity of workers is lowered.
Description
Technical field:
The utility model relates to a kind of mining anti-punching press combination reaming bit, is used for using under coal mine small hand-held formula erosion control rig to get out larger-diameter hole.
Background technology:
At present, big diameter borehole needs the drill bit of different-diameter to creep into respectively in Coal Production, and this just need repeat to creep into and often need more bit change, and holding time is long, inefficiency.
Summary of the invention:
The purpose of this utility model provides a kind of mining anti-punching press combination reaming bit, solves original big diameter borehole and need the problem that the drill bit of different-diameter creeps into respectively, and a drilling and forming hole has improved operating efficiency greatly, has reduced labour intensity.
The purpose of this utility model realizes as follows: this drill bit relates to brill storehouse body and the cutting edge on the body of brill storehouse, bore storehouse body front end, middle part and rear end cutting edge is all arranged, the cutting face diameter that the cutting face diameter that back level cutting edge forms when turning round forms when turning round greater than the prime cutting edge step by step, boring storehouse body afterbody is drillstock.Like this, the drill bit of different-diameter combined successively by order from small to large become one, top in use cutting edge gets out the less hole of diameter earlier, the cutting edge of back is reaming step by step again, the rear end cutting edge gets out the hole of the diameter that meets the requirements, and this combination erosion control companding drill is divided into three grades.
Boring multistage that the storehouse body all is provided with cutting edge on being every section becomes and wholely constitutes, and is to connect together by a formed by forging between section and the section, and the purpose of segmentation is to make boring and the reaming can once-forming, bit change more repeatedly when avoiding holing.
Cutting edge is to be welded on the CWD plated film alloy sheet that bores on the body of storehouse, and its cutting resistance is little, has good cutting ability.
Drillstock is the square drillstock that studs with the card beans, and is convenient, fast during connection, be easy to change.
The beneficial effects of the utility model are: improved operating efficiency greatly when being used for mine drilling, having shortened drilling time, reduced labour intensity.
Description of drawings:
Fig. 1 is the front view of the mining anti-punching press combination reaming bit of the utility model.
Fig. 2 is the right view of the mining anti-punching press combination reaming bit of the utility model.
The specific embodiment:
With reference to Fig. 1, Fig. 2, what this illustrated is the structure of three grades of reamings, and brill storehouse body bores storehouse body 7 by elementary brill storehouse body 6, middle rank and level brill storehouse, back body constitutes for 8 three sections.Elementary brill storehouse body 6 front ends have cutting edge 1, and middle rank bores storehouse body 7 cutting edge 2, and the back level is bored storehouse body 8 cutting edge 3, and cutting edge 1,2,3 is for being welded on the CWD plated film alloy sheet that bores on the body of storehouse, and cutting edge 1,2,3 respectively is two.The cutting face diameter that forms when the cutting face diameter of formation turns round greater than intermediate cutting edge 2 during 3 revolutions of back grade cutting edge, the cutting face diameter of formation when the cutting face diameter that intermediate cutting edge 2 forms when turning round turns round greater than cutting edge 1.Elementary brill storehouse body 6, middle rank bore storehouse body 7 and back 8 formed by forging of level brill storehouse body link together, and making and boring the storehouse body is that multistage becomes whole structure, and level brill storehouse, back body 8 afterbodys have drillstock 5, and it is the square drillstock that studs with card beans 4.The anti-punching press drill bit of this combination reaming is divided into three grades, calculates by boring torsion, the drill bit of different-diameter is combined successively by order from small to large become one.
Claims (4)
1, a kind of mining anti-punching press combination reaming bit, relate to the cutting edge that bores on storehouse body and the brill storehouse body, it is characterized in that: boring body front portion, storehouse, middle part and rear portion all has cutting edge (1,2,3), the cutting face diameter that the cutting face diameter that forms when back level cutting edge (2,3) revolution forms when turning round greater than prime cutting edge (1,2) step by step, boring storehouse body afterbody is drillstock (5).
2, mining anti-punching press combination reaming bit according to claim 1, it is characterized in that: the multistage that all is provided with cutting edge (1,2,3) on brill storehouse body is every section becomes whole formation.
