Abstract
One disclosed in the utility model is around limit opening bit, comprise drill body, described drill body comprises connection handle and the brill body in housing shape, connection handle is that integral type is formed with boring body, this connection handle is located at the bottom of boring body, bore medial surface and the equal concave-convex surface of lateral surface of body head, the brill body inner portion face of this concave-convex surface, lateral surface and top are all stained with by adhesive metal powder and the mixed mixture of diamond particles, and welded with the brill body head of concave-convex surface by the mode of vacuum brazing by the mixed mixture of adhesive metal powder and diamond particles, the head of this brill body offers chip area.Of the present utility modelly improve service efficiency, and at the adhesion diamond particles that the concavo-convex head side of drill bit can be more, drill bit carries out diamond particles abrasive product carries out perforate on drill bit not easily by Fast Wearing totally at high rotating speed, improve service life, increase work efficiency.
Description
Technical field
The utility model relate to a kind of for hole around limit opening bit.
Background technology
In prior art, the head lateral surface of opening bit is designed to the smooth surface of the positive arc-shaped of rule, then on the smooth surface of positive arc-shaped and both sides adhere to a certain amount of diamond particles, reach the object of grinding processed product portion being carried out to perforate, the product of this spline structure grinding perforate add the head grinding of drill bit in man-hour complete after, the diamond particles of side cannot play ablation, thus waste a lot of resource, reduce service efficiency, and be adhesion diamond particles less only on the smooth surface of positive circular arc at drill bit head, make drill bit when high rotating speed carry out abrasive product carry out perforate, diamond particles on drill bit easily by Fast Wearing totally, thus reduce the service life of drill bit, cause drill bit needs more bit change frequently when opening more hole, reduce operating efficiency.
Summary of the invention
The purpose of this utility model be deficiency in order to solve above-mentioned technology and design a kind of increase work efficiency and service life around limit opening bit.
Designed by the utility model around limit opening bit, comprise drill body, it is characterized in that: described drill body comprises connection handle and the brill body in housing shape, this connection handle is that integral type is formed with boring body, and this connection handle is located at the bottom of boring body, the medial surface of this brill body head and the equal concave-convex surface of lateral surface, and the brill body inner portion face of this concave-convex surface, lateral surface and top are all stained with by adhesive metal powder and the mixed mixture of diamond particles, and welded with the brill body head of concave-convex surface by the mode of vacuum brazing by the mixed mixture of adhesive metal powder and diamond particles, the head of this brill body offers chip area.In order to improve the operating efficiency of drill bit, so the technical scheme preferentially selected is: described brill body inner portion face and lateral surface concavo-convex also can be that undaform is concavo-convex or sawtooth pattern is concavo-convex.
In order to make the effect playing cooling drill bit when carrying out perforate work, the sidepiece of the described brill body in housing shape is provided with Cooling Holes.
In order to make drill bit and machine be connected and fixed better effects if, described connection handle entirety is stepped.
Adding around limit opening bit grinding perforate designed by the utility model, is attached to the effect that the diamond particles bored on body head all plays grinding man-hour, thus substantially increase service efficiency, drastically increase the service life of drill bit, further drill bit does not need frequently more bit change when opening more hole, increases work efficiency.Accompanying drawing explanation

In figure: drill body 1, brill body 2, connection handle 3, Cooling Holes 4, chip area 5.
Detailed description of the invention
Below by embodiment, the utility model will be further described by reference to the accompanying drawings.
Embodiment 1:
As shown in Figure 1, described by the present embodiment around limit opening bit, comprise drill body 1, described drill body 1 comprises connection handle 3 and the brill body 2 in housing shape, this connection handle 3 is that integral type is formed with boring body 2, and this connection handle 3 is located at the bottom of boring body 2, the medial surface of this brill body 2 head and the equal concave-convex surface of lateral surface, and the brill body 2 inner portion face of this concave-convex surface, lateral surface and top are all stained with by adhesive metal powder and the mixed mixture of diamond particles, and welded with brill body 2 head of concave-convex surface by the mode of vacuum brazing by the mixed mixture of adhesive metal powder and diamond particles, the head of this brill body 2 offers chip area 5, as shown in Figure 2, Figure 3 and Figure 4, described brill body 2 inner portion face and lateral surface concavo-convex also can be that undaform is concavo-convex or sawtooth pattern is concavo-convex, and the sidepiece of the described brill body 2 in housing shape is provided with Cooling Holes 4, and described connection handle 3 is overall stepped.
Meanwhile, the concavo-convex shape of described brill body 2 inner portion face and lateral surface also can set the demand of grinding work according to during perforate.
Use operation principle: utilize connection handle 3 and perforate with machine be connected, contact with needing the product of perforate after realizing drilling bit high-speed rotary, during perforate, the brill body 2 inner portion face of concave-convex surface (undaform is concavo-convex or sawtooth pattern is concavo-convex) and lateral surface more effectively can carry out grinding perforate operation.
Adding around limit opening bit grinding perforate described by the present embodiment, is attached to the effect that the diamond particles bored on body head all plays grinding man-hour, thus substantially increase service efficiency, and all can adhere to diamond particles in the concavo-convex inner portion face of drill bit and lateral surface, reach the effect of more adhesion diamond particles, when drill bit carries out diamond particles abrasive product carries out perforate on drill bit not easily by Fast Wearing totally at high rotating speed, thus improve the service life of drill bit, further drill bit does not need frequently more bit change when opening more hole, increase work efficiency.
