Abstract
The invention discloses a conducting wire and cable crimping pinchers. The wire and cable crimping pinchers comprise a hydraulic cylinder, a U-shaped pincher body and a die, wherein a piston in the hydraulic cylinder is connected with the die which is positioned on the outer lower part of the U-shaped pincher body; the other end of the hydraulic cylinder is connected with a joint which is used for connecting a hydraulic pump; both side walls of the upper end of the U-shaped pincher body are provided with openings; the die comprises a lower molding die and an upper molding die; the upper molding die is fixed on the upper part of the U-shaped pincher body through a die fixing pin; and the lower molding die is positioned on the lower part of the U-shaped pincher body and matched with the U-shaped inner wall of the U-shaped pincher body. The crimping pinchers adopt ultrahigh system pressure of 700 kg/cm<2> to reduce the volume and the weight of the pinchers, and simultaneously amplify the piston stroke to widen the crimping range. The upper end part of the U-shaped pincher body is provided with the die fixing pin, so that the operation is more convenient and the service life of the crimping pinchers is longer; due to a 7-degree pening of the lower molding die of the die of the crimping pinchers, a crimping pipe is convenient to load in and take out; and the width of a pressure tank guarantees that wires are not damaged and the next operation is not influenced.
Description
Technical field
The present invention relates to a kind of Press Plier, particularly a kind of Press Plier that adopts hydraulic way lead and cable to be carried out crimping.
Background technology
The actual conditions of maintenance engineering are installed according to power transmission and distribution, the lead of different size and cable need only instrument come crimping in different construction occasions, and be connected the crimping needs, volume that generally require instrument at first to be fit to unit in charge of construction's regular size lead and cable are urinated and worked in little space, in light weightly are convenient to work high above the ground and are most economical.Existing on the market product function scope is little, processing is coarse, relatively heavy, the life-span is short, inconvenient operation, and the effect after the crimping is also undesirable; The pincers pressing mold work that is used for conductor compression jointing the time exists lead or the traditional thread binding problem of or not keeping forging ahead of cable, also exists in addition and lacks clear and definite data demand in the crimping operation rules, so very big to the injury of lead.
Summary of the invention
In order to overcome defective of the prior art, the invention provides a kind of lead or cable of making things convenient for and pack into and take out, lead and cable Press Plier that suitable processing plurality of specifications, difformity crimping require.
To achieve these goals, technical scheme of the present invention is achieved in that a kind of lead and cable Press Plier, comprise hydraulic jack, U type caliper and mould, piston in the described hydraulic jack joins with the mould that is positioned at the outer bottom of U type caliper, the other end jointing of hydraulic jack, joint is used to connect hydraulic pump; Perforate on the two side of U type caliper upper end wears the mould steady pin in the hole; Described mould comprises dip mold and top die, and described top die is fixed in the top of U type caliper by the mould steady pin, and dip mold is positioned at the bottom of U type caliper, and matches with the U type inwall of U type caliper.
More specifically, have gathering sill on the sidewall of described dip mold, and on the inwall of the corresponding U type of dip mold gathering sill caliper guide finger is set, the guide finger on the U type caliper inwall matches with the gathering sill on the dip mold sidewall.
The gathering sill of opening on the described dip mold sidewall is one, and the guide finger on the inwall of U type caliper is two, and two guide fingers are on same horizontal line, and is in simultaneously in the gathering sill of dip mold.
Described mould steady pin is a spike, the less end in cross section is an insertion end, it is head, described head setting and the perpendicular pin-and-hole of nail body, the pin-and-hole bottom is provided with screw, is connected with spring on the screw, the top of spring connects lock pin, when the hole of mould steady pin from U type caliper two side passed, lock pin made it be unlikely to come off in the hole of U type caliper owing to the effect that is subjected to spring force is ejected outside the pin-and-hole thereby block the mould steady pin.
Piston outer wall in the described hydraulic jack is with spring, matches by guide ring with hydraulic jack with the join piston outer wall of contravention of dip mold in the U type caliper, and the other end outer wall of piston matches with hydraulic jack by back-up ring and O type circle.
For easy to carry, Press Plier is provided with belt, and an end of belt is connected the lower end of U type caliper, and the other end is connected the top of mould steady pin, and the function of belt is to prevent that the mould steady pin from coming off or lose.
When the splicing ear of lead or cable or splicing sleeve when being circular, the die cavity of described mould is hexagon or W shape concave-convex; When lead or cable splicing sleeve were Long Circle, described mould was called the pincers pressing mold, and die cavity is a Long Circle.
The opening of described dip mold is 7
0
Compared with prior art, beneficial effect of the present invention is:
1, the utility model adopts the operation principle of single loop hydraulic jack, mixes U type caliper and forms a complete Press Plier, is equipped with different moulds again and just can finishes the difform crimping requirement of plurality of specifications.Simple in structure, easy to use.
2, adopt 700kg/cm
2Extra high voltage system, the 150-350kg/cm that generally adopts with hydraulic tests such as domestic engineering trucks
2System pressure compare, significantly reduced the volume and weight of hydraulic cylinder; Amplified piston stroke simultaneously, made that the crimping scope is bigger.
3, adopt the single-action hydraulic cylinder of spring return, make operation more simple and convenient (not needing to join the double acting hydraulic pump).
4, U type caliper upper end wears the mould steady pin, makes more convenient operation, Press Plier longer service life.
5, the used mould process test of many times of the present invention, counterdie 7
0Open design make packing into of lead or cable and take out all easily that the width of indent guarantees that not hindering lead does not influence next step operation again, the thickness of mould has also made things convenient for the location at crimping position.
6, for the connection of soft copper lead or fortuitous conductor such as flat type copper wire, adopt W form point pressing mold, guarantee the reliable connection of conductor.
