The present invention is implemented as follows: a kind of for welding the band Cooling fixture of big section aluminum conductor cable, including difference
Equipped with semicircular arc groove and mutually matched upper fixture and lower fixture, the size and cable size of the semicircular arc groove
Match, it is characterised in that: copper fixture is respectively adopted in the upper fixture and lower fixture.It is identical that the upper fixture is divided into structure
Left and right two parts, the upper fixture and lower fixture are respectively hollow structure, in the left and right two parts chuck body of upper fixture
Internal hollow structure forms the upper cooling water channel matched with upper fixture moulding, hollow inside the chuck body of lower fixture
Structure forms the lower cooling water channel matched with lower fixture moulding, and the upper cooling water channel and lower cooling water channel stretch out corresponding folder
It is connected with water channel adapter tube at tool body exterior, is respectively formed water inlet, upper water-out mouth, lower water inlet and lower outlet, passes through
Outer loop water pump is mutually connected and be connected to rubber hose, forms whole circulation waterway, and the semicircular arc of the lower fixture is recessed
The middle part of slot is equipped with forming tank, and the depth of the forming tank is greater than 3~5mm of depth of semicircular arc groove, and width is 30~
40mm.The aluminium conductor of two sections of cables to be welded is fixed on the both ends of lower fixture by left and right two parts of the upper fixture respectively,
And it is located at the middle part of lower fixture at docking, welding material is heat-fused in formation solder joint at forming tank by soldering appliance.
The bottom of the upper fixture is equipped with screw rod, and the lower fixture is equipped with the through-hole cooperated with the screw rod, described
Left and right both ends of the left and right two parts respectively with lower fixture of upper fixture be fixedly connected by screw rod and fastening nut.
The beneficial effects of the present invention are: the present invention has good cooling effect using cooling water channel design is come into contact in a large area,
Effective protection cable insulation will not be damaged in the welding process due to high temperature, meanwhile, fixture can be stablized in welding
Fixed cable ends to be welded, and guarantee that Forming Quality is stablized at solder joint, make to weld more convenient operation, conductor is not curved after welding
Song, weld conductor is full after welding, there is preferable resistive performance.
