Description

A kind of carbide alloy reaming bit
Technical field
The utility model belongs to drill bit field, particularly relates to a kind of carbide alloy reaming bit.
Background technology
Drill bit goes out through hole or blind hole in order to drilling on solid material, and can to the cutter of existing hole reaming.Conventional drill bit mainly contains fluted drill, centre drill, chit drill, depth drill and cylindrical drill.Though reamer counterbit can not be holed on solid material, also they are included into drill bit one class traditionally.The course of work dig pit operation time, drill bit, with vertical shaft rotary, moves axially simultaneously.Soil is cut under the moment of torsion and responsive to axial force of drill bit, is raveled under the extruding and centrifugal action of working-blade, forms native stream and presses to hole wall, simultaneously along page elevator to earth's surface.When native stream moves to without hole wall stop place, because centrifugal action hack is thrown around hole, complete the process of digging pit
Reamer is generally used for semifinishing or the eventually processing in hole, for the expansion of the preprocessing before cutting with scissors or grinding or blank hole, has two to three lands, and without chisel edge, add man-hour guide effect good, axial drag is little, and machining condition is better than holing.Reamer is different from the effect that drill bit plays, and reamer and drill bit are all utilize cutting edge to carry out drilling; Bit drills bottom outlet, reamer is expanded the bottom outlet of bit drills, eventually passes reamer and carries out strand and cut, make the precision in hole, fineness reaches requirement.It is low to there is hardness in existing reamer, wears no resistance, the problem that service life is short.
Utility model content
The technical problems to be solved in the utility model is that reaming bit hardness is low, and wear no resistance, service life is short.
For solving the problems of the technologies described above, the utility model provides following technical scheme: a kind of carbide alloy reaming bit, is formed by connecting, it is characterized in that by drill body and drillstock two parts: described drill body is provided with S shape bite and front bite; The structure of described drillstock is cylinder; Described drillstock offers positioning groove near terminal position.
Further, the ∞ font body of the structure of described drill body to be two ends be straight end face, described drill body head is provided with front bite, and the angle of described front bite blade and drill body axis is 15 ~ 35 °.
Further, described drill body is provided with horizontally disposed S shape bite along ∞ font position, and described S shape bite and drill body are monolithic molding, and described S shape bite blade and drill body level angle are 30 ~ 45 °;
Further, described drill body also includes two groove for cuttings, described groove for cuttings extends to bottom from the start-up portion of drill body in a helical pattern, on arbitrary cross section of drill body, groove for cuttings is all positioned at position diametrically opposed to each other in drill body plane, and drill body is divided into four parts by described two groove for cuttings uniformly.
Further, the structure of described drillstock is slender cylinder, and length is 5 ~ 7cm, and the rearward end periphery along described cylinder drillstock offers 2 detents up and down, and the diameter of described detent is 0.5 ~ 1cm.
The beneficial effects of the utility model are as follows:
1, front bite, S shape bite and row are cut groove and effectively combine by drill bit of the present utility model, during work, front bite elder generation and absorption surface, then S shape bite cuts again, reduce the boring dynamics of S shape bite, protect S shape bite, the service life adding drill bit, simultaneously high, the row of drilling efficiency cut unobstructed;
2, drill bit of the present utility model is provided with two groove for cuttings on drill body, described two groove for cuttings extend to bottom from front end in a helical pattern, along on arbitrary cross section of drill body, groove for cuttings is all positioned at position diametrically opposed to each other in drill body plane, the groove for cuttings of this symmetric figure, and row's bevel is long-pending large, it is fast that row cuts speed, not easily causes broken accumulation of cutting;
3, surface texture of the present utility model is ∽ shape, is drilling through in the process of hole like this, reduces stress surface, and increase borehole strength, be conducive to the automatic entrance-exit in working angles, stock-removing efficiency will improve greatly;
4, drillstock end of the present utility model offers positioning groove, and such positioning groove design serves fastening effect, Embedded drillstock, effectively can prevent drill bit landing from electric drill machine.
Accompanying drawing explanation
If Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Drawing reference numeral: 1, front bite, 2, drill body, 3, row cuts groove, 4, S shape bite, 5, drillstock, 6, positioning groove
For making utility model object of the present utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
As shown in Figure 1, a kind of carbide alloy reaming bit, is formed by connecting by drill body 2 and drillstock 5 two parts, it is characterized in that: drill body 2 is provided with S shape bite 4 and front bite 1 structure of Novel electric hammer drill bit of the present utility model; The structure of drillstock 5 is cylinder; Drillstock 5 offers positioning groove 6 near terminal position.The ∞ font body of the structure of drill body 2 to be two ends be straight end face, drill body 2 front end is provided with front bite 1, and the angle of front bite 1 blade and drill body 2 axis is 15 ~ 35 °.
Drill body 2 is provided with horizontally disposed S shape bite 4 along ∞ font position, S shape bite 4 and drill body 2 are monolithic molding, S shape bite 4 blade and drill body 2 level angle are 30 ~ 45 °, surface texture is ∞ shape, drilling through in the process of hole like this, reducing stress surface, increasing borehole strength, be conducive to the automatic entrance-exit in working angles, stock-removing efficiency will improve greatly.
Drill body 2 also includes two groove for cuttings 3, groove for cuttings 3 extends to bottom from the start-up portion of drill body 2 in a helical pattern, on arbitrary cross section of drill body 2, groove for cuttings 3 is all positioned at position diametrically opposed to each other in drill body 2 plane, drill body 2 is divided into four parts by two groove for cuttings 3 uniformly, the groove for cuttings 3 of this symmetric figure, and row's bevel is long-pending large, it is fast that row cuts speed, not easily causes broken accumulation of cutting.
The structure of drillstock 5 is slender cylinder, length is 5 ~ 7cm, rearward end periphery along cylinder drillstock 5 offers 2 detents 6 up and down, the diameter of detent 6 is 0.5 ~ 1cm, such positioning groove 6 design serves fastening effect, Embedded drillstock 5, effectively can prevent drill bit landing from electric drill machine.
Above-described embodiment is preferred embodiment of the present utility model; it is not the restriction to technical solutions of the utility model; as long as without the technical scheme that creative work can realize on the basis of above-described embodiment, all should be considered as falling within the scope of the rights protection of the utility model patent.
