Description
Technical field
The utility model relates to a kind of weld mold of aluminium busbar, especially relates to aluminium busbar weld mold under a kind of complicated position, belongs to welding technology field.
Background technology
In recent years, China's aluminum i ndustry fast development, electrolytic aluminium output hero occupies first place in the world, and aluminium production technology reaches or in many aspects close to advanced international standard.In Aluminum Electrolysis Production, for improving the output of current efficiency and aluminium, the current strength of aluminium cell is in rising trend, the current strength of Liancheng branch company of current Chinese Aluminium Co., Ltd aluminium cell oneself reach 300KA.So large DC current makes electrolytic cell and creates the high-intensity magnetic field that diameter reaches several meters around, and magnetic field intensity can reach 180 Gausses as calculated.
Aluminium busbar often understands accidental damage aborning, welding of aluminum bus has main two kinds of methods at present: one is welded with gas welding, but this welding method is only applicable to weld thin plate, and inefficiency, there is limitation in actual applications, only can be used for the sectional repair of aluminium soft ribbons; Another kind adopts the method for arc-welding to repair.But due to the existence of high-intensity magnetic field, when welding striking, spark splashes, can not form arc column, arc blow and splash phenomena seriously, not only increase labour intensity and difficulty of construction, also cause effectively welding.
There is a kind of high-intensity magnetic field interference, raising welding quality, reduction labour intensity, female existing original position self-spread welding repair method of a kind of aluminium rapidly simple to operate can avoided can overcome above-mentioned defect at present, namely adopt and weld from melting welding agent.Weld mold carries out the important tool from fusion welding, although there is this mould, welding position more complicated, narrow sometimes, girth can not meet mould and place requirement, common die cannot use, and this just needs exploitation a kind of for the particular manufacturing craft under complicated situation.
Utility model content
Technical problem to be solved in the utility model is to provide aluminium busbar weld mold under a kind of complicated position.Use this mould to weld aluminium busbar, by high-intensity magnetic field interference, safe and reliable, simple to operate.
The utility model is achieved by the following scheme:
Aluminium busbar weld mold under a kind of complicated position, the crucible comprising band rundown conduits and the four pieces of graphite cakes be attached at respectively outside groove to be welded, wherein one piece of graphite cake there is central through hole, another two pieces of corresponding graphite cakes clamp with jig, described central through hole aims at aluminium busbar fault location, and the rundown conduits of described crucible is connected with central through hole.
Described crucible is that graphite is made.
Dirty guide hole is arranged at the bottom of described crucible, and dirty guide hole connects rundown conduits.
Described jig is made up of the telescopic leading screw of U-shaped support and support both sides.
The utility model has following effect:
(1) Split type die ensure that its manufacturability, low cost, the easily property dismantled, safe and reliable.Whole mould is manufactured by graphite, can Reusability, reduces totle drilling cost, have the feature of high-performance and high life, on average can weld 30-50 groove.
(2) drainage catheter of graphite crucible both can be positioned at centre, and also can eccentric design, catheter length and internal diameter can be determined according to aluminium busbar welding position and defect size, had fully adapted to small space and the narrow dimension at welding scene under complex situations.In addition, if conduit is oversize, can conduit outer wall add heat-insulation layer or in the catheter portion's acetylene heat, ensure that molten metal has good mobility.
(3) four pieces of graphite cake assembling design ensure that its left-right universal and broad applicability, are not subject to bevel for welding at aluminium busbar position, shape, size and aspect effect.
(4) safe and reliable, in the utility model, the crucible bottom of the band rundown conduits that graphite is made adopts recessed village aluminium flake or tin sheet as from fused plug, can automatically melt from fused plug when the molten metal that self-propagating thermit reaction generates reaches predetermined temperature, pass through molten metal, avoid and manually smash out and slag inclusion phenomenon, not only improve quality, Er Qiean
Good perfection.

Detailed description of the invention
Below in conjunction with Figure of description, the detailed description of the invention that the utility model is done is described in detail.
As shown in Figure 1, the crucible 2 that the utility model comprises band rundown conduits 3 and the four pieces of graphite cakes 4 be attached at respectively outside groove to be welded, wherein one piece of graphite cake there is central through hole 7, another two pieces of corresponding graphite cakes clamp with jig 5, described central through hole 7 aims at aluminium busbar fault location, and the rundown conduits 3 of described crucible 2 is connected with central through hole 7.
Dirty guide hole 6 is arranged at the bottom of described crucible 2, and dirty guide hole 6 connects rundown conduits 3.
As shown in Figure 2, the inside of crucible is cylindrical and cylinder bottom is hemispherical and has dirty guide hole in bottom.When using this device, placing from molten liner in dirty guide hole, is the concavity aluminium flake of thickness 1mm from molten liner, according to the aluminium busbar damage location depth, can select 2 ~ 3 from holding the stacked use of liner.Dirty guide hole is connected with rundown conduits, and the length of rundown conduits and internal diameter can be determined according to aluminium busbar defective locations and groove size, and are connected with the upper central through hole of carbon barrier, make molten metal flow to bus fault location.
The side all around of aluminium busbar is covered by graphite cake 4, and is connected with aluminium busbar by four pieces of graphite cakes with the jig shown in Fig. 4, forms a welding die cavity.Steel jig can regulate the stretched screw mandrel of the left and right sides according to the size of aluminium busbar, for clamping mold.
