Description

A kind of long sharp mouth carbide burrs
Technical field
The utility model belongs to drill bit field, particularly relates to a kind of long sharp mouth carbide burrs.
Background technology
Cutter on brill, drilling machine, rig, can cause hole on workpiece or rock.Xu Chi " Goldbach's Conjecture's oil head ": " in 1956, China's bored material was somewhat nervous, and drill bit is not enough." 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.
Drill bit of the prior art many employings drill bit drills through, and drills through intensity low, and row cuts obstructed, and what this can have influence on drill bit drills through work, greatly reduces the operating efficiency of drill bit.
Utility model content
It is low that the technical problems to be solved in the utility model is that drill bit drills through intensity, and row cuts obstructed, inefficiency.
For solving the problems of the technologies described above, the utility model provides following technical scheme: a kind of long sharp mouth carbide burrs, is connected and composed by drillstock and drill body two parts, it is characterized in that: the structure of described drill body is made up of apex point and drill body body two parts monolithic molding; Described drill body body by two ends be the drill body body leading section of the ∞ font body of straight end face and cylinder drill body body rearward end on the same axis monolithic molding form; Described apex point is provided with front bite along helical position, and described front bite and apex point are monolithic molding; Described drill body body leading section is provided with the secondary bite of horizontally disposed S shape along ∞ font position, the secondary bite of described S shape and drill body body are monolithic molding, and the secondary bite blade of described S shape and described drill body body level angle are 30 ~ 45 °; The structure of described drillstock is elongate cylinder body structure, in one end of drillstock, near end position, is provided with positioning groove.
Further, the structure of described apex point is truncated cone-shaped, and the minimum diameter of described truncated cone-shaped apex point and the ratio of maximum gauge are 1:3.
Further, described apex point, drill body are 1:1:1.5 with the maximum gauge ratio of drillstock.
Further, described drill body body leading section also includes two groove for cuttings, described groove for cuttings extends to bottom from the start-up portion of drill body body leading section in a helical pattern, on arbitrary cross section of drill body body, groove for cuttings is all positioned at position diametrically opposed to each other in drill body plane, and drill body body leading section is divided into four parts by described two groove for cuttings uniformly.
Further, described positioning groove is the groove offering two semicircle strips along cylinder drillstock periphery.
The beneficial effects of the utility model are as follows:
1, front bite, secondary these two cuttves of bite of S shape and groove for cuttings also have positioning groove effectively to combine by drill bit of the present utility model, realize twin-stage boring, once-forming, and chip removal is unobstructed, realizes the smooth of boring cutting face, and firmly installs;
2, the setting of the ratio of the maximum gauge of apex point of the present utility model, drill body and drillstock, is beneficial to the stable of structure in boring procedure, not easily occurs the phenomenon ruptured;
3, drill bit of the present utility model is provided with two groove for cuttings on drill body body, described two groove for cuttings extend to bottom from front end in a helical pattern, along on arbitrary cross section of drill body body, groove for cuttings is all positioned at position diametrically opposed to each other in drill body 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;
4, have the groove of two the semicircle strips offered along cylinder drillstock periphery outside drillstock of the present utility model, such groove design serves fastening effect, Embedded drillstock, effectively can prevent drill bit landing from install machinery;
5, before drill bit of the present utility model adopts, bite and the secondary bite of S shape are worked in coordination, and accelerate cutting speed, ensure that the fineness in cutting face.
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, the secondary bite of S shape, 3, drill body body, 4, row cuts groove, 5, drillstock, 6, positioning groove, 7, apex point
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 long sharp mouth carbide burrs, is connected and composed by drillstock 5 and drill body two parts, it is characterized in that: the structure of drill body is made up of apex point 7 and drill body body 3 two parts monolithic molding the structure of the sharp mouth carbide burrs of length of the present utility model; Drill body body 3 by two ends be the drill body body leading section of the ∞ font body of straight end face and cylinder drill body body rearward end on the same axis monolithic molding form; Apex point 7 is provided with front bite 1 along helical position, and front bite 1 is monolithic molding with apex point 7; Drill body body leading section being provided with the secondary bite 2 of secondary bite 2, the S shape of horizontally disposed S shape is monolithic molding along ∞ font position with drill body body 3, and secondary bite 2 blade of S shape and described drill body body 3 level angle are 30 ~ 45 °; Before adopting, bite 1 and the secondary bite 2 of S shape are worked in coordination, and accelerate cutting speed, ensure that the fineness in cutting face.
