Abstract
The utility model relates to a concrete drill, which comprises a cutter body, a cutter pipe and a cutter head. The cutter body and the cutter pipe are fixedly connected, and the cutter pipe and the cutter head are fixedly connected. The concrete drill is characterized in that the cutter head adopts a diamond cutter head, and the diamond cutter head comprises an annular cutter head and a flaky cutter head. The concrete drill is concise in structure, high in drill machining efficiency, long in service life and good in production stability.
Description
Technical field
The utility model relates to a kind of five metals machining tool, particularly a kind of concrete hole drill.
Background technology
Diamond concrete hole drill cutter head partly is to rely on low-melting alloy powder hot pressed sintering to form in the existing market, then with extension bar, connect handle and be connected.This way has several shortcomings: 1, behind low-melting alloy powder hot pressed sintering, bond strength is low, causes the cutter working strength low, so pore wall thickness must be thickeied; 2, low-melting-point metal ambient stable property is poor, is prone to oxidation takes place at normal temperatures, influences product quality; 3, the carcass wearability is good, causes cutting edge selfishness difference etc.
Summary of the invention
The utility model technical problem to be solved is to overcome existing above-mentioned deficiency in the prior art, and a kind of drill bit working (machining) efficiency height, long service life, the stable good concrete hole drill of production are provided.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: this concrete hole drill; Comprise cutter hub, cutter pipe, cutter head; Cutter hub is fixedly connected with the cutter pipe; The cutter pipe is fixedly connected with cutter head, it is characterized in that said cutter head adopts diamond segment, diamond segment comprise ring-type cutter head and sheet cutter first two.
The utility model is simple for structure, and drill bit working (machining) efficiency height, long service life, production are stablized.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
Referring to Fig. 1, the utility model concrete hole drill comprises cutter hub 1, cutter pipe 2, diamond segment 3, and cutter hub 1 is fixedly connected with cutter pipe 2, and cutter pipe 2 is fixedly connected with diamond segment 3.Present embodiment diamond segment 3 is formed by the diamond and the cobalt alloy powder sintering of prior art, and volume proportion is: diamond dust content 20% to 25%, and cobalt alloy powder 80% to 75%: and contain the cobalt amount in the cobalt alloy powder more than 80%.
3 fens ring-type cutter heads of present embodiment diamond segment and sheet cutter first two, the ring-type cutter head is used for small dimension, the sheet cutter head is used for big specification.
The simple deformation or the combination of every the utility model embodiment technical scheme and technical characterictic all should be thought the protection domain that falls into the utility model.
