Abstract

The utility model provides a diamond bit with continuous waveform drill teeth with the same wall thickness, and belongs to the field of diamond machining tools. The bit comprises a bit basal body and the continuous waveform drill teeth with the same wall thickness. The bit basal body and the drill teeth are integrally. The wall thicknesses of the drill teeth are 0.01-10mm and identical, the drill teeth are continuous, and the thickness (bit machining direction) of a working layer is 0.01-100mm. The inner wall of the outer wall of the drill teeth are provided with protrusions and water tanks, the outer side of the protrusions of the inner wall is an outer wall water outlet tank, and the inner side of the protrusions of the outer wall is an inner wall water inlet tank. Sharpness of the bit is greatly improved through inner protrusions and outer protrusions of the drill teeth, inner tanks and outer tanks of the drill teeth play roles in cooling and chip removal, possibility of burning of the bit is greatly reduced, and thus machining efficiency of hole drilling is greatly improved.

Description

Bore the tooth diamond bit Deng the wall thickness continuous wave

(1) technical field

The utility model is the boring bar tool of hard crisp nonmetallic materials such as a kind of processed glass, pottery, stone material, be exactly specifically diameter be the diamond bit of 1-150mm.

(2) background technology

The diamond grooved bit that is used for hard brittle material punchings such as glass, pottery, stone material at present comprises the individual layer electroplated diamond bit, bronze sintered diamond drill bit, brazed diamond drill bit.Individual layer electroplated diamond bit processing sharpness height wherein, but make its processing life-span very short because its working lining partly has only one deck diamond to constitute, workman's more bit change that will shut down has frequently increased working strength of workers, influences the efficient of large-scale production greatly; The bronze sintered diamond drill bit processing life-span is long, but because its process limitation makes its sharpness difference and very unstable, draining row cuts difficulty, puts the first edge on a knife or a pair of scissors also will in the processing work process drill bit of blunt again, and working strength of workers is also very high; Brazed diamond drill bit is welded on the matrix because of diamond, adhesion height and diamond exposure rate height make it very sharp, service life is also long than individual layer electroplated diamond bit, but still mono-layer diamond is in work after all, and its life-span does not reach the service life of bronze sintered diamond drill bit far away.

(3) summary of the invention

The utility model be exist separately at present various diamond bits or sharpness low, or the life-span is low, or the labor strength height, or blocks shortcomings such as bit freezing easily and design.

The technical solution of the utility model: wait the wall thickness continuous wave to bore the tooth diamond bit, comprise bit matrix and bore tooth, bit matrix and brill tooth are connected into one, and it is characterized in that: it is continuous to bore tooth, the wall thickness unanimity; The inner and outer wall that bores tooth all is distributed with projection and tank.

The utility model also can be such: the inwall projection of boring tooth and outer wall projection distribute or screw type distributes and the hand of spiral is opposite or consistent in the type that bores on the tooth wall linearly.

The utility model also can be such: inwall projection, inwall tank, outer wall tank and the outer wall projection of boring tooth have multiple projection profiles: the outer wall tank sideline of the inwall projection baseline of inwall projection, the inwall tank baseline of inwall tank, outer wall tank, the outer wall projection sideline of outer wall projection are respectively by circular arc, elliptic arc, line segment, irregular curve or above in two or more opening figure that connect and compose constitute.

The utility model also can be such: the wall thickness that bores tooth is the 0.01--10 millimeter, in same section perpendicular to the drill bit direction of feed, in the inwall projection sideline of inwall projection the inwall tank sideline of the point of the most close drill bit working face centre of gyration and inwall tank away from the some place of the drill bit working face centre of gyration be the concentrically ringed semidiameter in the center of circle with the drill bit working face centre of gyration, namely the depth capacity of inwall tank is the 0.01--10 millimeter; The inwall projection sideline width of inwall projection is more than or equal to 0.01 millimeter, and the width in the inwall tank sideline of inwall tank is greater than 0.01 millimeter.

The utility model also can be such: brill tooth inwall projection, inwall tank, outer wall tank, outer wall projection comprise one or more profiles; Bore the same projection of tooth inside and outside wall and tank profile and comprise one or more dimensions; Bore the quantity of the same projection of tooth inside and outside wall and the same dimensions of tank profile more than or equal to one.

The utility model also can be such: inwall projection and outer wall projection are being bored evenly distribution or irregular distribution on the tooth wall.

The utility model also can be such: boring the delivery port that the tooth wall has or some perforation inside and outside walls.

The utility model also can be such: the inwall that bores tooth has projection and tank, and outer wall is the face of cylinder.

The utility model since its unique manufacture craft and structure have the following advantages: 1. the drill bit drilling is sharp, has improved process velocity greatly.2. working face is continuous seamless ring, and drilling is steady, is difficult for collapsing the limit.3. boring tooth is continuous loop, and the wall thickness unanimity does not have the defective that has tooth wall thin layer place that follow-up process water groove causes, and the brill dental transition is firm, is difficult for taking place to bore the tooth phenomenon of rupture.4. because the existence of projection makes its processing mechanism partly change the impact grinding into by former continuous grinding, improved process velocity, projection also is the part that grinds away at first, has improved the self-sharpening of drill bit own, need not polishing in the course of work.5. because the existence of projection makes the cooling water effect of its working position very good, chip removal at the right time, the easier drill bit burn bit freezing problem of avoiding.
