Description

The Portable conducting wire Press Plier

Technical field

The utility model relates to a kind of power construction power tool, particularly a kind of Portable conducting wire Press Plier.

Background technology

At present, in the operating repairs work of power construction and equipment, wire and wire, wire is a technical work of often implementing with tight connection of equipment, the main tool of completing this technical work is hydraulic tongs, its existing problem is: cost is high, limited by the place, hydraulic tongs often uses easy leakage of oil, during to large wire diameter or copper cash crimping, the faults such as leakage of oil more easily occur, bring great inconvenience for the site operation personnel.

The Portable conducting wire Press Plier is the actual needs design according to construction and Overhaul site, and is small and exquisite portable, do not have Leakage, practical.

The utility model content

The purpose of this utility model is to solve the problems referred to above that the existing wire pressing tool that uses exists, and a kind of portable, practical conductor compression jointing tongs is provided.

For achieving the above object, the novel conductive wire Press Plier is provided with a workbench, is 3 supports that equilateral triangle arrange to install and fixes with 3 bolts rotations on the workbench following table, and the counter-force bar also is bolted on above-mentioned same table top; Position, center line both sides at the workbench upper table surface, by base, hook, drift bolt, that binding clip is relatively fixing, on two inwalls of binding clip, respectively be provided with groove one, pressing line die is arranged in groove, above pressing line die, piston moving up and down is installed, and jackscrew leans on piston, and a spanner is fixed in the jackscrew upper end, below pressing line die, be provided with the location drift bolt.

Crimp is comprised of two identical moulds, and the width of its die width and groove is complementary, and the centre of crimp is the line ball hole, and after two die assemblies, the line ball hole is equilateral six prismatics.

In the piston upper end, be provided with triangular groove, groove matches with the triangle shaped ends of jackscrew.

Two bases are housed below binding clip, are separately fixed at the center line both sides of workbench upper table surface, one is matched with hook, and another is with the drift bolt cooperation and with the relative workbench upper table surface that is fixed on of binding clip.

Because the novel conductive wire Press Plier is portable, easy to operate and durable, both facilitated power construction and plant maintenance maintenance, the economy that also improves.

Embodiment

Below in conjunction with accompanying drawing, Portable conducting wire Press Plier and structure thereof are elaborated:

By Fig. 1, Fig. 2, Fig. 3 as seen, the Portable conducting wire Press Plier is provided with a workbench 12, support is arranged below workbench, be equilateral triangle and arrange that 3 supports 13 of installing are fixing with 3 bolt rotations on workbench 12 following tables, steadiness during for assurance work, be provided with a counter-force bar 14, counter-force bar 14 also is bolted on the following table of workbench 12; At the position, center line both sides of workbench 12 upper table surfaces, by base 9, hook 11, drift bolt 10 is relatively fixing with binding clip 8, namely an end of binding clip 8 can utilize hook 11 lockings, and the other end can rotate or integral body be laid down around drift bolt 10, to be convenient for carrying; On two inwalls of binding clip 8, respectively be provided with groove 5 one, pressing line die 6 is arranged in groove 5, groove is of a size of: groove depth 3mm, groove width 11mm, the high 90mm of groove, above pressing line die 6, piston 4 moving up and down is installed, jackscrew 2 is spun on the internal thread that is welded as a whole with piston, its lower end leans on piston 4, help movable parts lubricated by oiling groove 3 oilings, a spanner 1 is fixed in jackscrew 2 upper ends, and rotary spanner 1 can make jackscrew 2 move downward, pushing piston 4 compresses pressing line die 6 and makes and is crimped wire and compresses moulding; Below pressing line die 6, be provided with a location drift bolt 7, be used for the fixedly position of pressing line die 6; As seen from Figure 3, location drift bolt 7 is cylindrical, is placed in two circular holes on binding clip 8.

Crimp 6 is comprised of two identical moulds, and the width of its die width and groove 5 is complementary, and after combination, at the place, centre of crimp 6, forms the line ball hole of equilateral six prismatics; For the wire that guarantees that conductor compression jointing tongs can the crimping different size, this conductor compression jointing tongs is provided with one group of 10 crimp altogether, can tackle the crimping of 16mm, 25mm, 35mm, 50mm, 70mm, 95mm, 120mm, 150mm, 185mm, 240mm diameter wire.

The moving both vertically of piston 4 when guaranteeing crimping in piston 4 upper ends, is provided with a triangular groove, and groove matches with the triangle shaped ends of jackscrew 2.

As seen from Figure 4, two bases 9 are housed below binding clip 8, two base shapes are different, be separately fixed at the center line both sides of workbench 12 upper table surfaces, one is matched with hook 11, lockable hook 11, another is semicircle, with drift bolt 10 cooperations and with relative workbench 12 upper table surfaces that are fixed on of binding clip 8.
