Description
Technical field
The invention belongs to drill bit field, particularly relate to a kind of composite plate target drill.
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
Also need to use drill bit in plank field, plank drill bit common on market is all direct boring, but common drill bit is used for the breakage that composite plate easily causes composite plate.
Summary of the invention
To be common plank drill bit easily cause composite plate damaged for the boring of composite plate to the technical problem to be solved in the present invention.
For solving the problems of the technologies described above, the invention provides following technical scheme: a kind of composite plate target drill, is characterized in that: by apex point, drill body, safety screen and drillstock four part be formed by connecting; One end of described drill body is connected with apex point, and described drill body and apex point are monolithic molding; The other end of described drill body is connected with safety screen, and described drill body and safety screen are monolithic molding; The other end of described safety screen is connected with drillstock, and the connected mode of described safety screen and drillstock is welded type; Described drill body is provided with S shape bite; Described drillstock is provided with positioning groove near terminal position; The structure of described safety screen is cylinder.
Further, the structure of described apex point is cone, and the drift angle of described cone apex point and the angle of drill body horizontal axis are 7 ~ 15 °, and the cone of described cone apex point is high is 4 ~ 6cm.
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.
Beneficial effect of the present invention is as follows:
1, apex point, S shape bite, safety screen and row are cut groove and effectively combine by drill bit of the present invention, and apex point positions and drills through, S shape bite carries out secondary drilling, improve the borehole strength of drill bit, accelerate the boring dynamics that broken discharge of cutting also reduces S shape bite simultaneously, protection drill bit;
2, drill bit of the present invention 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, drill body surface texture of the present invention 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 invention offers positioning groove, and such positioning groove design serves fastening effect, Embedded drillstock, effectively can prevent drill bit landing from electric drill machine;
5, offering of safety screen of the present invention, can avoid in boring procedure, brokenly cuts accumulation, to be attached on drill bit thus to hinder the normal operation of drill bit.
