Description
Technical field
The present invention relates to power transformation engineering construction wire crimping aid field, relate in particular to the auxiliary jig of a kind of steel reinforced aluminium conductor crimping.
Background technology
At present, during power transformation engineering construction distribution, need make the joint of copper or aluminium at lead two ends, various lines footpath, little line footpath lead uses special-purpose Crimping Pliers, makes more conveniently, can satisfy the joint quality requirement; The above major diameter lead of 10mm generally all is used in big current applications, when having loose contact, can cause contact heating phenomenon, and serious meeting causes that contact scorification, lead blow, and makes discovery from observation, and there is following problem in its manufacturing process:
1) because lead is multicore, and its end easily disperses, be difficult to fitly inject in the sleeve pipe of aluminium hydraulic pressed connecting pipe, behind the crimping sleeve, the wire termination skin can not all reliably contact with the aluminium hydraulic pressed connecting pipe inwall, and when having loose contact, heating is inevitable; The flow process of crimping at present is: lead colligation, line and mould crimping, before conductor compression jointing, lead is adopted the aluminum steel colligation, and cumbersome, and consume more wire rod.
2) when short lead is carried out crimping, especially length at one meter with interior, when an end crimping finishes, during the crimping other end, the wire termination core is inconsistent at the effect lower stress of press power, the pine that tightly has that has, occur easily so-called " Chinese enkianthus ", lax lead is under electric current " skin effect " effect, and it is overheated to take place, meeting scaling loss when serious, but do not have effective ways to avoid at present.
Summary of the invention
The purpose of this invention is to provide the auxiliary jig of a kind of steel reinforced aluminium conductor crimping, overcome the deficiencies in the prior art, before wire termination injects the aluminium hydraulic pressed connecting pipe sleeve pipe, at wire termination inserting section rear jig is set, make wire termination fitly be pressed into a bundle, i.e. convenient grafting, local core is loose because of unbalance stress in the time of avoiding suppressing again, improves big line footpath conductor compression jointing quality.
For solving the problems of the technologies described above, technical scheme of the present invention is:
Jig is assisted in a kind of steel reinforced aluminium conductor crimping, comprise chuck and core pressing mold, described chuck comprises chuck and following chuck, hinged being oppositely arranged in one side of the last chuck of arc and following chuck, the another side of last chuck and following chuck is respectively along the parallel lip limit that is provided with of axis direction, and middle part, lip limit is damaged, and the eyelet bolt head is arranged on the bearing pin at damaged place, lip limit of chuck or time chuck, the screw rod of eyelet bolt is provided with wing nut, is respectively equipped with alignment pin on the intrados of last chuck and following chuck; Described core pressing mold comprises top die and dip mold, and top die and dip mold make up its inner arc diameter dimension of back and core specification coupling, and the alignment pin place on described top die and the dip mold extrados on the intrados of corresponding upward chuck and following chuck is provided with location notch.
Endoporus is oblate after described top die and the dip mold pressing, and minimum place, aperture is than the little 1-2mm of core format diameter.
Described alignment pin be one or two or more than two.
Be respectively equipped with screwed hole on described top die and the dip mold, this screwed hole is corresponding with the installing hole on last chuck and the following chuck respectively.
Described chuck is aluminum alloy material, and the surface is through oxidation processes; The core pressing mold is that carbon steel is through preservative treatment.
Compared with prior art, the invention has the beneficial effects as follows: 1) simple in structure, be easy to make, easy to use.2) before wire termination injected the aluminium hydraulic pressed connecting pipe sleeve pipe, wire termination fitly was pressed into a bundle, convenient pegging graft, and can adjust the colligation position at any time according to insertion depth.During 3) to the crimping of short lead two ends, after an end crimping is finished, adopt jig to clamp before other end crimping, pressure guiding line stage casing disperses in the time of avoiding suppressing, and prevents the local broken lot of lead, improves the joint of the above major diameter lead of 10mm effectively and makes quality.

Embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described further:
Seeing Fig. 1, is the auxiliary jig example structure schematic diagram of a kind of steel reinforced aluminium conductor crimping of the present invention, comprises chuck and core pressing mold, and chuck is aluminum alloy material, and the surface is through oxidation processes; The core pressing mold is that carbon steel is through preservative treatment, this chuck comprises chuck 1 and following chuck 2, the last chuck 1 of arc and one side of following chuck 2 are by bearing pin one 3 hinged being oppositely arranged, the another side of last chuck 1 and following chuck 2 is respectively along the parallel lip limit 4 that is provided with of axis direction, 4 middle parts, lip limit are damaged, eyelet bolt 5 heads are arranged on down on the bearing pin 26 at damaged place, lip limit of chuck 2, and the screw rod of eyelet bolt 5 is provided with wing nut 7, are respectively equipped with alignment pin 8 on the intrados of last chuck 1 and following chuck 2; This core pressing mold comprises top die 9 and dip mold 10, top die 9 and dip mold 10 make up its inner arc diameter dimensions of back and core specification coupling, and alignment pin 8 places on top die 9 and dip mold 10 extrados on the intrados of corresponding upward chuck and following chuck are provided with location notch 11.
