Abstract
This content mainly relates to a drill bit can be replaced to quick detach, and it is mainly by wear -resisting matrix, compound piece cutter body, and parts such as broken stem stem constitute, and wear -resisting matrix be whole vacuum quenching and tempering, and the surface adhesion has tungsten carbide coating, and compound piece cutter body is the cutting tool that can go on replacing with the supporting use of wear -resisting matrix, the appearance is worn and torn in the use, but pair recombination piece cutter body is changed fast under falling the condition of piece. Drill bit in the past mostly is overall structure, and the in -process then needs to change whole drill bit if appear damaging drilling to cause the wasting of resources. A drill bit structure, than traditional drill bit, the matrix abrasion strength is high, all cutter bodies that drill bit can be replaced to quick detach provided is but that pair recombination piece cutter body is dismantled and is more renewed the cutter body and a wasting of resources, reduction in production cost that the stem stem all adopts the fastening screw fastening with the matrix, and it is swiftly convenient to change, makes things convenient for the workman to operate and avoid promptly.
Description
Technical field
This utility model relates generally to a kind of replaceable drill bit of Quick Release, and it is mainly used in coal mine gallery probing and mining rock drilling etc. and creeps into operation, especially in the drilling operation of superhard rock stratum, the convenient quick-replaceable for composite sheet of drilling bit cutter hub, reducing cost.
Background technology
In the middle of geological drilling industry, hard formation and hard coal seam probing are always up the formation condition often met, bore operation is carried out for this people's many employings diamond bit, than hard alloy, diamond compact is processed by diamond single crystal, so having the advantages that hardness is high, in the process that hard formation and hard coal seam are holed, there is remarkable result.When carrying out high-speed cutting and creeping into, drill bit blade easily runs into rock intercalation or hard spot rock, in the case that the infringement of diamond compact is very big, usually thus result in drill bit and fall sheet, abrasion, and market most drill bits at present are integral type structure, namely bit matrix is made directly with diamond compact and welds, and needs whole drill bit is replaced when diamond compact abrasion occurs or falls sheet time, production cost is caused to increase, the wasting of resources.Traditional diamond matrix is divided into the many forms such as machining and matrix-type, then carries out vacuum modifier treatment, and surface does not carry out hardening coat processing, although comparing with common iron, organizational structure compactness increases, and hardness is necessarily strengthened, but compares than rock, it wears no resistance, service life is short, with the repeatedly grinding of rock in the middle of, bit body serious wear, not there is reusable ability, replacing green bit can only be eliminated.In sum, how can solve the problem that the diamond compact bit wasting of resources in use, control production cost, become industry personnel and unanimously think urgent problem.
Utility model content
The novel purpose of this use is to provide a kind of replaceable drill bit of Quick Release, it mainly includes the key components such as wear resistant matrix, diamond cutter hub and broken stem stem, diamond compact and bit matrix is made to adopt modular construction, directly diamond cutter hub can be replaced when abrasion occurs in drill bit, without changing bit matrix, only need to fix with trip bolt when diamond cutter hub is installed with wear resistant matrix, it is not necessary to complicated installation process, convenient operation.
The wear resistant matrix of the replaceable drill bit of a kind of Quick Release is then to carry out vacuum modifier treatment to after being processed molding with the raw material of processing wear resistant matrix, ensure materials microstructure compact structure, with there is relatively uniform material hardness, finally wear resistant matrix is carried out surface carbonation tungsten coating processing, carcass case hardness is made to reach more than HRC65-70, can also sulfuration resistant, erosion-resisting feature while there is wearability, it is adaptable to various bad grounds.Bottom wear resistant matrix, processing has cone screw thread or other fast class connected modes of inserting, and convenient and tool joint is attached interworking.
The end face processing of the diamond cutter hub of the replaceable drill bit of a kind of Quick Release has locating shaft, and inside end processing has screw thread, it is possible to install fixing connection with wear resistant matrix, and this structure is convenient to be connected, dismounting simplicity.The processing of the diamond cutter hub other end has composite sheet mounting groove, and composite sheet is welded and fixed firmly through heating in medium frequency, and in use, composite sheet can directly change diamond cutter hub after there is the phenomenon such as sheet, abrasion to drill bit.
Broken stem stem one end processing of the replaceable drill bit of a kind of Quick Release has compound film trap, same the same with diamond cutter hub is welded and fixed firmly by composite sheet through heating in medium frequency, and other end processing fastens with trip bolt after having screw thread and wear resistant matrix installation.
The replaceable drill bit global design structure of a kind of Quick Release is for convenience of directly changing composite sheet position on the basis be changed without bit matrix, cost can be saved greatly, and do not affect operative to use, drilling effect in differently face, top layer is obvious, use suitable in the probing of all kinds of industries, applied range, obtains the consistent favorable comment of user of service.
Accompanying drawing illustrates:
Fig. 1 is the front view of the replaceable drill bit of a kind of Quick Release
Fig. 2 is the connection view of the replaceable drill bit of a kind of Quick Release

Wherein, 1 wear resistant matrix；2 composite sheet cutter hubs；3 broken stem stems；4 trip bolts；5 gauge bars
Wherein, 101 side apopore；102 cones are threaded；103 eject water hole
Wherein, 201 diamond compact；202 steel bodies；203 trip bolt junctions
Detailed description of the invention
As follows with reference to the figure contained in accompanying drawing concrete practical explanation:
Shown in figure, first wear resistant matrix 1 is processed, each wing of wear resistant matrix 1 is provided with the hole, location for installing composite sheet cutter hub 2, being provided with side apopore 101 between each wing and eject water hole 103, bottom is provided with the threaded body of cone 102 or other quick socket connection modes.Wear resistant matrix 1 carries out vacuum modifier treatment after machining, and wear resistant matrix finally carries out surface carbonation tungsten coating processing, makes carcass case hardness reach more than HRC65-70.Composite sheet cutter hub 2 includes composite sheet 201 and steel body 202, and steel body 202 one end is provided with the female thread body 203 coordinated with trip bolt 5.Fastening with trip bolt 4 after installing composite sheet cutter hub 2 on each wing of wear resistant matrix 1, the centre trip bolt 4 that same broken core body 3 is arranged on wear resistant matrix 1 fastens.Each wing of wear resistant matrix 1 is welded with gauge bar 5.The above detailed description of the invention is the statement that the replaceable drill bit basic structure of a kind of Quick Release is assembled, and based on other form that above content is modified and improves, all should be encompassed in this patent context.
