Description
Technical field
The utility model relates to power transformation engineering construction wire crimping aid field, relates 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 a multicore, its end is prone to disperse, and is difficult to fitly inject in the sleeve pipe of aluminium hydraulic pressed connecting pipe, and 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 the utility model provides the auxiliary jig of a kind of steel reinforced aluminium conductor crimping; Overcome the deficiency of prior art, before wire termination injects the aluminium hydraulic pressed connecting pipe sleeve pipe, jig is set at wire termination inserting section rear; Make wire termination fitly be pressed into a bundle; Promptly convenient pegging graft, 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, the technical scheme of the utility model is:
Jig is assisted in a kind of steel reinforced aluminium conductor crimping, comprises chuck and core pressing mold, and said 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 of lip limit defect 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; Said 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 said 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 said top die and the dip mold pressing, and minimum place, aperture is than the little 1-2mm of core format diameter.
Said alignment pin be one or two or more than two.
Be respectively equipped with screwed hole on said top die and the dip mold, this screwed hole is corresponding with the installing hole on the following chuck with last chuck respectively.
Compared with prior art, the beneficial effect of the utility model is: 1) simple in structure, be easy to make, and 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 accomplished, before other end crimping, adopt jig to clamp, pressure guiding line stage casing disperses in the time of avoiding suppressing, and prevents the local broken lot of lead, improves the joint fabricating quality of the above major diameter lead of 10mm effectively.

Embodiment
Be described further below in conjunction with the embodiment of accompanying drawing the utility model:
See Fig. 1; Be the auxiliary jig example structure sketch map of a kind of steel reinforced aluminium conductor crimping of the utility model, comprise chuck and core pressing mold, this chuck comprises chuck 1 and following chuck 2; The last chuck 1 of arc and one side of following chuck 2 are through 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, and 4 middle parts, lip limit are damaged, and eyelet bolt 5 heads are arranged on down on the bearing pin 26 of lip limit defect of chuck 2; The screw rod of eyelet bolt 5 is provided with wing nut 7, is 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; Its inner arc diameter dimensions and core specification coupling after top die 9 makes up with dip mold 10, 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.
Endoporus be oblate after top die 9 and dip mold 10 pressings, and minimum place, aperture is than the little 1-2mm of core format diameter, can satisfy the distortion behind the core pressurized, assurance line ball pressure.
