Abstract
The utility model discloses an annular cutter bit sinter molding assembling mould of a diamond thin-wall drill. The annular cutter bit sinter molding assembling mould of the diamond thin-wall drill comprises a mould core, a concave mould which is arranged on the mould core in a sleeved mode. The concave mould is cylinder-shaped and is equally divided into a first concave mould, a second concave mould and a third concave mould. A boss is respectively arranged on the sides, close to the mould core, of the first concave mould, the second concave mould and the third concave mode. An annular upper pressing head and an annular lower pressing head are arranged between the mould core and the concave mould. A water groove moulding concave groove is arranged in the annular lower pressing head. The annular cutter bit sinter molding assembling mould of the diamond thin-wall drill is capable of effectively controlling the height of an annular cutter bit and guaranteeing the high density of the annular cutter bit and the equidistance of water notch grooves. The concave mould is equally divided into three parts. Separation between the annular cutter bit and a graphite mould after hot pressing cools can be achieved conveniently. During a mould removal, the concave mould can be detached from the annular cutter bit in three parts. Defects that the cutter bit contains graphite or the edge of the graphite falls and the like during an annular cutter bit compression moulding are overcome. Appearance and quality of the diamond thin-wall drill is guaranteed.
Description
Technical field
The utility model relates to the graphite jig technical field, is specifically related to a kind of diamond core drill bit annular tool-tip sintering forming assembling die, is applicable to the manufacturing of graphite.
Background technology
In recent years, diamond core drill bit is widely used in industrial civil building structure of modification industry as the important means of mixed clay structure thing static(al) cutting, dismounting, has also widened the new approaches of mineral exploration engineering technical development simultaneously.
At present, building trade and unit in charge of construction are in pipeline installation and drill hole on wall, and it is integral sintered that the thin diamond wall that uses is drilled with monodentate cutter head welding drill body, annular cutter head welds drill body and annular cutter head and drill body.Monodentate cutter head welding drill body thin-walled drill in use has the defective of the cutter head that easily comes off, the thin-walled drill difficult drop-off cutter head of annular cutter head, but the dismounting from graphite jig of annular cutter head is relatively more difficult in process of production, causes a large amount of breakages of graphite jig.The utility model is not enough and custom-designed for this just.
The utility model content
The purpose of this utility model is the problems referred to above that are for the prior art existence, a kind of diamond core drill bit annular tool-tip sintering forming assembling die is provided, simple in structure, easy to operate, be easy to form removal, the annular cutter head of production is stable, difficult drop-off, graphite carcass relative density is up to 97%, yield rate 99%.
Above-mentioned purpose of the present utility model is achieved through the following technical solutions:
A kind of diamond core drill bit annular tool-tip sintering forming assembling die, comprise core rod, also comprise the die that is set on the core rod, die is that annulated column shape and 3 is divided into the first die, the second die and the 3rd die, close core rod one side of the first die, the second die and the 3rd die is provided with boss, be provided with annular seaming chuck and annular push-down head between core rod and the die, be provided with the tank shaping groove on the annular push-down head.
The utility model compared with prior art has the following advantages:
1, annular push-down head can effectively be controlled the height of annular cutter head with becoming equidistant intercalation cutter head tank moulding inserted block, guarantees the high density of annular cutter head and the isometry of mouth of a river groove;
2, die is formed by 3 etc. minutes component combinations, made things convenient for annular cutter head behind Hot-press cooling with the mask work of graphite jig;
3, die can rapidly be separated into 3 with annular cutter head when form removal, occurs the cutter head graphitiferous when having avoided compressing annular cutter head, graphite jig falls the defectives such as limit, has fully guaranteed outward appearance and the quality of diamond ring thin-walled drill.
Description of drawings
Fig. 1 is schematic top plan view of the present utility model;
Fig. 2 is longitudinal profile schematic diagram of the present utility model;
Fig. 3 is cutter head tank moulding inserted block of the present utility model and the schematic diagram that cooperates of annular push-down head.
Among the figure: 101-the first die; 102-the second die; 103-the 3rd die; The 2-core rod; 3-annular seaming chuck; The 4-cutter head; 401-cutter head tank moulding inserted block; 5-annular push-down head; 501-tank shaping groove; The 6-boss.
The specific embodiment
Below in conjunction with accompanying drawing the technical solution of the utility model is described in further detail.
Embodiment 1
Such as Fig. 1 ~ shown in Figure 3, a kind of diamond core drill bit annular tool-tip sintering forming assembling die, comprise core rod 2, also comprise the die that is set on the core rod 2, die is that annulated column shape and 3 is divided into the first die 101, the second die 102 and the 3rd die 103, close core rod 2 one sides of the first die 101, the second die 102 and the 3rd die 103 are provided with boss 6, are provided with annular seaming chuck 3 and annular push-down head 5 between core rod 2 and the die, are provided with tank shaping groove 501 on the annular push-down head 5.
Die is comprised of the first die 101, the second die 102 and the 3rd die 103 of five equilibrium, and the first die 101, the second die 102 and the 3rd die 103 close up fixing according to order, be combined into die.There is boss 6 to locate as core rod under the die, annular space looping cutter head forming cavity between core rod 2 and the die, be provided with the annular push-down head 5 of tank shaping groove 501 in annular cutter head forming cavity bottom, tank shaping groove 501 equidistantly arranges on annular push-down head 5, cutter head tank moulding inserted block 401 couplings on tank shaping groove 501 and the cutter head 4.The cutter head powder is put on the lower pressure ring that is embedded with cutter head tank moulding inserted block 401, then puts into annular seaming chuck, and after all installed, graphite jig is put into the annular cutter head in hot press workspace can be compressing.
The utility model annular push-down head can effectively be controlled the height of annular cutter head with the tank shaping groove 501 that becomes equidistant intercalation cutter head tank moulding inserted block 401, guarantees the high density of annular cutter head and the isometry of mouth of a river groove; Die is that 3 grades divide component combination to form, made things convenient for annular cutter head behind Hot-press cooling with the mask work of graphite jig; Die can rapidly be separated into 3 with annular cutter head when form removal, occur the cutter head graphitiferous when having avoided compressing annular cutter head, graphite falls the defectives such as limit, has guaranteed outward appearance and the quality of diamond ring thin-walled drill.
