Description
Technical field
The utility model is related to metal die for connecting technical field, and in particular to one kind is led for recovering high-tension cable copper
The exothermic welding mould of the isometrical connection of body.
Background technology
At present, conductor connection is by the way of crimping in conventional high-tension cable connector manufacture craft, by two branch cable conductors
One conductor is spliced into by mechanical force.But the feelings of mechanical force reduction can occur over time for this crimping conductor
Relative displacement occurs for condition, two branch cable conductors, produces discharging gap, causes cable connector to puncture when serious.
Utility model content
In order to overcome above-mentioned deficiency of the prior art, the purpose of this utility model is to provide a kind of for recovering high pressure
The exothermic welding mould of the isometrical connection of cable copper conductor, can realize exothermic weld, be made using metallic compound chemical reaction heat
For thermal source, by the molten metal of overheat, direct or indirect heating work, formed in the die cavity under the mould definite shape,
Size, meets the joint made by flame welding of engineering demand.
The utility model solve technical scheme that its technical problem used for：
A kind of exothermic welding mould for being used to recover the isometrical connection of high-tension cable copper conductor, including by identical mould A parts
Merge with mould B parts and form, mould A parts and mould the B part is each disposed with half-reaction chamber, half guiding gutter from top to down
With half die cavity, the reaction chamber for placing exothermic weld agent, guiding gutter and die cavity are sequentially formed after merging；The reaction chamber is provided with
With the wire guide of reaction chamber UNICOM, the wire guide is used to place that the lead of exothermic weld agent in the reaction chamber can be lighted, the type
Chamber is laterally set, and two ends have gateway, and two conductors for welding stretch into the die cavity by the gateway at two ends respectively；Institute
State guiding gutter upper end and be provided with gasket seal；The detachable smog for sealing is provided with the upper end open of the reaction chamber
Cover.
Further, screw hole is provided with mould A parts and mould the B parts, both are fastened by screw rod and positioned.
Further, the diameter of half die cavity on mould A parts and mould the B parts can be designed according to conductor diameter.
Further, mould A parts and mould B the part side adds iron plate.
Further, mould A parts and mould the B parts are made up of graphite.
Further, it is provided with fire prevention rock wool layer in the fume hood inner top layer.
The beneficial effect that the utility model is brought has：Exothermic weld is realized, is made using metallic compound chemical reaction heat
For thermal source, by the molten metal of overheat, direct or indirect heating work forms a setting in the die cavity under the mould
Shape, size, meet the joint made by flame welding of engineering demand, it is therefore prevented that the conductor in joint production process be subjected to displacement etc. it is bad after
Really, and the discharging gap that prevents, prevent the joint made by flame welding from puncturing.
Brief description of the drawings
Below in conjunction with the accompanying drawings and specific embodiment the utility model is described in further detail,
Accompanying drawing 1 is the utility model structural representation；
Accompanying drawing 2 is the joint face structural representation of the utility model mould A parts and mould B parts.
Embodiment
Referring to the drawings 1 and Fig. 2, a kind of exothermic welding mould for being used to recover the isometrical connection of high-tension cable copper conductor, including
By identical mould A parts（Symbol A#）With mould B parts（Symbol B#）Merging is formed, during merging, and adjustment two is used for leading for welding
Body transverse direction contact surface, gap is 3 ~ 5mm, and mould A parts and mould B parts are merged, is fastened and positioned through screw hole 3 and 6 with screw rod,
Conductor is set to pass through die cavity holes 5, two connector slots are located on die cavity center line, and the upper end of guiding gutter 4 is sealed with pad.In reaction chamber 2
Middle addition exothermic weld agent, penetrates fairlead 1, die top fume hood 7 is sealed by lead, prevents that high-temperature slag from flying out wound
People, puts combustion wire, and the copper finally melted is molded in die cavity.
Mould is made up of hard refractory graphite material, and heat resistance and self lubricity are good, and shaping speed is fast, size is smart
Really, the even density after welding, can directly be polished, isometrical recovery cable conductor.
Screw hole 3 and 6 is used for mould and fastens positioning, and side is screwed hole.
Mould side installs iron plate 8 additional, is screwed on mould, improves mould strength.
There is fire prevention rock wool layer detachable fume hood, centre, places high temperature harmful substance and flies out mould.
The diameter of die cavity holes 5 can make mould according to the cross-section of cable, it is adaptable to 35 ~ 3500mm2 of area of section cable.
It should be noted that simply preferred embodiment of the present utility model described above, the utility model not office
It is limited to above-mentioned embodiment, as long as it reaches technique effect of the present utility model with identical means, should all belongs to this practicality new
