Abstract
The invention discloses a novel high-speed hollow drill bit. The novel high-speed hollow drill bit is characterized in that a drill body is composed of a main drill body, a cutting part and a drill handle, one end of the main drill body is connected with the cutting part, and the main drill body and the cutting part are integrally formed; the other end of the main drill body is connected with the drill handle, and the main drill body and the drill handle are integrally formed; the drill handle is of a fine and long cylinder structure, and a positioning groove is formed in the position, close to the end, of one end of the drill handle. According to the drill bit, a sawtooth-shaped cutter, a ventilation hole and the positioning groove are effectively combined, and the purposes of high drilling strength, smooth chip removal and firm installing are achieved.
Description
Technical field
The invention belongs to drill bit field, particularly relate to a kind of novel high speed hollow boring bit.
Background technology
Drill bit is a kind of rotation and head end has the instrument of cutting power, general with carbon steel SK or high-speed steel SKH2, the materials such as SKH3 through milling or rolling again through quenching, grind after tempering heat treatment and form, Drilling operation on metal or other materials, its scope of application is extremely wide, can apply to the toolroom machines such as drilling machine, lathe, milling machine, electric hand drill use.
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.
Existing drill bit is solid bit, and it exists following shortcoming: 1. Heavy Weight, and in the relatively-stationary situation of weight, the length of drill bit must be restricted, and therefore guidance quality is good not, becomes hole perpendicularity lower; 2. the impact dynamics that produces in unit are of solid bit is little, and penetration rate is slow; 3. can not carry out deslagging while drill bit impact, production efficiency is low, and penetration rate is slow.
Summary of the invention
It is low that the technical problem to be solved in the present invention is to solve bit bore intensity, and process velocity is low.
For solving the problems of the technologies described above, the invention provides following technical scheme: a kind of novel high speed hollow boring bit, it is characterized in that: described drill body by drill body body, cutting part and drillstock three part form, one end of described drill body body is connected with cutting part, and described drill body body and cutting part are one of the forming; The other end of described drill body body is connected with drillstock, and described drill body body and drillstock are one of the forming; 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 drill body body is hollow cylinder, and the center of described drill body body offers two symmetrical air vents, and the front end of described drill body body is provided with cutting part.
Further, described cutting part is made up of serrated chip cutter, and the front end face of drill body body is divided into 4 parts by described serrated chip cutter uniformly, and serrated chip cutter length is 2 ~ 4cm, and wide is 0.4 ~ 0.7cm, and height is 0.2 ~ 0.4cm.
Further, the length of described slender cylinder drillstock is 10 ~ 14cm, and diameter is 2 ~ 3cm.
Further, described positioning groove is the groove offering four semicircle strips along cylinder drillstock periphery.
Further, described drillstock and the diameter of drill body body are than being 1:4.
Beneficial effect of the present invention is as follows:
1, serrated chip cutter, air vent and positioning groove effectively combine by drill bit of the present invention, reach borehole strength high, and row cuts the object of unobstructed and fastening installation;
2, in cutting part of the present invention, have employed serrated chip cutter, add cutting hardness;
3, have the groove of 4 the semicircle strips offered along cylinder drillstock periphery outside drillstock of the present invention, such groove design serves fastening effect, Embedded drillstock, effectively can prevent drill bit landing from install machinery;
4, ventilation hole structure of the present invention, is conducive in the process of running up, the timely discharge of heat, avoids high temperature stack-up to cause the unexpected fracture of drill bit.
