Abstract

The invention discloses a welding powder packaging structure. The welding powder packaging structure comprises a shell (1) and a cover body (2), wherein the cover body (2) hermetically covers the shell (1); a thin wall part (21) which is convenient for inserting an ignition strip (3) is arranged on the cover body (2); both the cover body (2) and the shell (1) are made of metal copper. The welding powder packaging structure has the advantages that the shell is packaged by copper in a fully sealing way, so that high sealing performance is realized, welding powder is prevented from being deteriorated by damping, and the service life is long; the shell is adopted for packaging, so that convenience is brought to transportation, contact with open fire can be effectively avoided, and higher transportation safety is realized; convenience is brought to use since the packaging shell only needs to be placed into a welding die during operation; after welding, the copper shell is molten into molten copper which becomes a part of a welding powder formula and is molten integrally with a copper cable, so that shell residues are prevented, and cleanliness and environmental friendliness are realized; moreover, thin copper wires do not need to be added into the welding powder since the copper shell replaces the copper wires originally placed into the welding powder, so that the preparation cost of the welding powder is effectively reduced.

Description

Welding powder packaging structure

Technical field

The present invention relates to copper cable welding production technical field, especially a kind of welding powder packaging structure for copper cable welding.

Background technology

The welding powder packaging structure that ERICO company of the existing U.S. produces, comprise iron-clad, have for heat insulation graphite paper in iron-clad inner liner, the lid paper (note: blowing-by) and bar of igniting that prevent welding powder from dropping out is provided with at iron-clad end face, this structure has transport and easy to use and safety of operation, the feature that work efficiency is high, concrete structure can referring to company's site (http://www.erico.com/products/CadweldPlus.asp), but, this packaging structure, there is following shortcoming, 1, the packaging shell of this packaging structure adopts iron-clad, after welding, wrapped housing and graphite paper is stayed at weld mold, so not only waste material, post-processing bothers, productive costs is high, the more important thing is not environmentally, 2, packaging structure blowing-by, welding powder is easy to make moist and go bad, and shelf-life durations is short, 3, because this packaging shell is iron, so in order to improve the composition of copper in welding powder, need to add a certain amount of thin copper wire in welding powder formula, thus increase the preparation cost of welding powder, 4, because housing is iron-clad, so have the composition of iron in weld part, thus electric conductivity and welding fastness is reduced, therefore, the structure of this packaging also needs further improvement.

Summary of the invention

Technical matters to be solved by this invention provides a kind of hermetically sealed, long shelf-life, the safe and welding powder packaging structure that welding fastness is good low without waste of material, environmental protection, welding powder preparation cost, easy to use.

The present invention solves the problems of the technologies described above adopted technical scheme: this welding powder packaging structure, include housing, it is characterized in that: described welding powder packaging structure also includes lid, described lid covers hermetically to be put on housing, described lid is provided with the thinner wall section that bar of conveniently igniting inserts, described lid and housing are made by metallic copper.

As improvement, described thinner wall section preferably can be positioned at the thin-walled layer in the middle part of lid.

Further improvement, the thickness of described thin-walled layer is that namely broken thickness is stabbed in bar end one of igniting.

Improve, described thinner wall section shape can be preferably suitable with the end face of bar of igniting again, and the width of thinner wall section and length are to equal or slightly larger than the width of bar of igniting and length.

As improvement, described lid may be selected to be the disk-shaped structure of medial recess, and the periphery of lid is fixed together with housing seal to be wound on casing peripheral.

As improvement, the outside face of described housing and lid also electrodepositable has not only attractive in appearance but also antirust tin layers.

As improvement, described housing can be preferably taper shape, suitable with the conical wall shape of weld mold.The shape of certain housing also can be other other shape, as cylindrical etc., specifically can determine by designing requirement.

As improvement, described housing is made up of upper tapering and hypocone, and upper tapering and hypocone are the disposable integrative-structure be stamped to form.Epicone portion and hypocone can not certainly be divided into, specifically can determine by designing requirement.

Further improvement, the angle of upper tapering and hypocone junction can be preferably 130 ~ 140 degree.

Further improvement, the tapering of the hypocone of described housing can be preferably 145 ~ 160 degree.

Compared with prior art, advantage of the present invention is as follows: one, because this packaging structure housing adopts the hermetically sealed packaging of copper body to form, good airproof performance, and welding powder can not make moist and go bad, so long shelf-life; Two, adopt housing packaging, not only convenient transportation, and can effectively avoid contacting with naked light, make safe transportation; Three, easy to use, packaging shell of the present invention is only needed to be placed in weld mold during operation, after welding, the part that copper shell is molten into copper water and becomes in welding powder formula and be molten into one with copper cable, and it is residual to no longer include housing, not only clean environment firendly, and do not need to add thin copper wire again in welding powder, because copper shell instead of the copper wire originally in welding powder, thus significantly reduce welding powder preparation cost; Four, weld fastness and conduct electricity very well, because housing of the present invention adopts copper to be made, the composition of iron can not be mixed in welding process, then improve electric conductivity and weld fastness; Five, because adopt copper shell, to heat be absorbed in copper shell fusion process, so effectively alleviate the damage to weld mold, thus extend the service life of weld mold; Six, welding powder of the present invention does not need pyrophoric powder, as long as bar of igniting inserts in welding powder, bar of igniting energising can be lighted a fire, so safety easy to operate; Seven, the outside face of housing of the present invention is also electroplate with tin layers, effectively can not only prevent copper body from corroding and getting rusty, and extend the guaranteeing the quality property time further, tin is metal more better than copper electric conductivity simultaneously, weld part can be fused into with copper water, then again improve the electric conductivity of copper cable.Certain packaging structure of the present invention can not only weld the plain conductor that copper cable also may be used for welding iron cable or other applicable welding, specifically can determine by actual conditions.
