Description
Vynález sa týká sposobu regulácie zvéracieho drotu do přesného miesta vo zvarovom spoji počas zvárania alebo navárania elektrickým oblúkom, najma ▼ ochraně plynu a zváracieho horáka pře tento sposob.The invention relates to a method of regulating a clamping wire to a precise location in a welded joint during arc welding or arc welding, in particular to protect the gas and the welding torch from this method.
Při elektrickom oblúkovom zváraní odtavujúcou sa elektrodou, najme v ochraně plynu, je potřebné vo zvláštnych prípadoch vytvoriť zvar vo velmi úzkej medzere a v značnej hlbke spoja.Medzeru spoja, ktorú tvoria tekmer rovnoběžné bočné steny na celej výške spoja, je potřebné zvárať v polohe vodorovnéj zhora, alebo v iných polohách. Pre formovanie a kvalitu zvaru je potřebné priviesť zvárací drot od ústia medzery do přesného miesta na dne spoja a tu při hoření oblúka zvárací drot regulovať. Přesným miestom spoja je například střed spoja alebo miesto mimo středu spoja na jeho dne. Aby sa zvárací drot dal do přesného miesta spoja nastaviť, je potřebné, aby sa z přímočarého směru rovnoběžného s bočnými stěnami medzery, v príalušnej vzdialenosti od dna spoja, vhodným sposobom stranové vyosil. Přitom je potřebné, aby sa hodnota alkosti vyosenia dala regulačně před zváraním nastaviť a v priebeho horenia oblúka regulovať. Ďalej je přitom potřebné, aby zvárací drot a nastavenou hodnotou vyosenia směroval striedavo na jednu z bočných stien medzery a to kolmo, ako aj v zmenitelnom uhle. Pri zváraní alebo naváření v úzkej medzere a vysokom spoji, kde je potřebné vyhotoviť vačší počet zvarových húsenío vo viacerých vrstvách, nie je možné bez přívodu drotu do přesného miesta spoja a udržiavaní zváracieho drotu v tomto mieste a bez zvléátnehoIn electric arc welding with a melting electrode, in particular in gas protection, it is necessary in special cases to create a weld in a very narrow gap and at a considerable joint depth. The joint gap, which consists of toroid-parallel side walls over the entire joint height, , or in other positions. For forming and quality of the weld it is necessary to bring the welding wire from the mouth of the gap to the exact place on the bottom of the joint and here to regulate the welding wire during the burning of the arc. The exact point of the joint is, for example, the center of the joint or a place outside the center of the joint at its bottom. In order to be able to adjust the welding wire to the exact point of the joint, it is necessary to offset laterally from the rectilinear direction parallel to the side walls of the joint at a close distance from the joint bottom. In this case, it is necessary that the offset value of the offset can be adjusted in a controlled manner before welding and can be regulated during the arc burning. It is also necessary for the welding wire and the set offset value to be directed alternately to one of the side walls of the gap, both perpendicularly and at a variable angle. When welding or welding in a narrow gap and a high joint, where it is necessary to produce a greater number of welds in multiple layers, it is not possible without feeding the wire to the exact point of the joint and keeping the welding wire in this place and without

199 875 uaporiadania zváracieho horáka pre tento sposob dosiahnuí pri zváraní kvalitný zvarový spoj.199 875 of the welding torch arrangement for this method achieves a high-quality welding joint during welding.
V súčasnej době sú známe sposoby reguláoie a zariadenia, ktoré pri výstupe zváracieho drotu zo zváracieho horákp vytvárajú stranové zakrivenie a tým vyoaenie zváracieho drotu z priameho směru. Dosahuje ae to například deformáciou zváracieho drotu v podávacom mechanizme před vstupom do zváracieho horáka. Deformovaný zvárací drot sa čiastočné udržuje i v priamočarom vedení vo zváracom horáku ohyb, a ktorým z horáka vystupuje. Nedoetatky aposobov reguláoie sú však v tom, že náaledkom nerovnoměrněj pevnosti zváracieho drotu na jeho dížke, vlivom vinutí zo svitku, sa deformácia ovlivňuje, Deformécia je závislé dalej od dížky zváracieho drotu v horáku. Týmito sposobmi nemožno dosiahnul najma rýchlu reguláciu při vytváření vyosenia a naopak pri vyrovnávaní, čím sposob při zváraní nie je doetatočne pružný. Konštrukcie podávačích mechanizmov pre podévanie a deformáciu zvéracích drotov je komplikovaná a náročná pre obsluhu.Presently, control methods and devices are known which, when the welding wire exits the welding torches, create a lateral curvature and thus a welding wire from the direct direction. This is achieved, for example, by deforming the welding wire in the feed mechanism before entering the welding torch. The deformed welding wire is partially maintained even in the rectilinear guide in the welding torch and by which it exits the torch. However, the shortcomings of the regulator are that, due to the uneven strength of the welding wire on its length due to the coil winding, the deformation is affected. The deformation is further dependent on the length of the welding wire in the torch. In this way, it is not possible to achieve at least a rapid regulation during the formation of the offset and, on the contrary, during the alignment, whereby the welding method is not flexible enough. The construction of the feed mechanisms for the feeding and deformation of the clamping wires is complicated and labor intensive.
Sú známe tak iato sposoby reguláoie a zariadenia, kde sa 9tranové zakrivenie a tým vyoeenie zváracieho drotu z povodného směru dosahuje při výstupe zo zváracieho horáka pomocou koncoviek na konci zváracieho horáka. Stanovéné zakrivenie zváracieho drotu sa vytvéra v týchto prípadoch čelným alebo stranovým prietlakom na zvárací drot v kontaktněj koncovke umiesteným regulačným elementom. Reguláoia vyoaenia na stanovenú hodnotu je možná v týchto prípadoch len před zváranim a v přiebehu horenia oblúka aa nedá doregulovať. Konštrukčné prevedenia ei okrem toho vyžaduje vačšie rozměry koncoviek horáka, čo v případe vysokých a úzkých spojov je nepoužitelné, lebo neumožňuje přívod zváracieho drotu na dno spoja.Known control systems and devices are also known in which the 9-side curvature and hence the welding wire from the flood direction is achieved when exiting the welding torch by means of terminals at the end of the welding torch. In this case, the curvature of the welding wire is created by the front or side pressure on the welding wire in the contact terminal by the control element. In these cases, the regulation of the set value is only possible before welding and during the arc burning and cannot be regulated. Furthermore, the design ei requires larger dimensions of the torch terminals, which is unusable in the case of high and narrow joints because it does not allow the welding wire to be fed to the bottom of the joint.
Sú áalej známe epóeoby regulécií a zariadenia, kde sa stranové zakrivenie zváracieho drotu z priamočiarého směru dosahuje pevným ohybom kanále pre vedenie zváracieho drotu v dolnej časti zváracieho horáka, například v koncovke zváracieho horáka. Vyoeenie zváracieho drotu na stanovenú hodnotu je dané velkoeíou ohybu kanála koncovky. 1 v tomto případe nie je možná reguláoia velkosti vyoaenia v přiebehu horenia oblúka, So je rovnako nevýhodou sposobu.Further, there are known epoches of regulations and devices where the lateral curvature of the welding wire from a rectilinear direction is achieved by a rigid bending of the welding wire guide at the lower part of the welding torch, for example in the welding torch tip. The welding of the welding wire to the specified value is determined by the size of the bend of the terminal channel. In this case, it is not possible to control the magnitude of the firing during the arc burning. So is the disadvantage of the method.
Uvedené nevýhody sa vynálezom do značnéj miery odstránia. Podstata aposobu reguláoie směru zváracieho drotu do přesného miesta vo zvarovom spoji počas zvárania alebo navárania elektrickým oblúkom, najma v ochraně plynu, podlá vynálezu spočívá v tom, že zvárací drot aa reguluje z počiatočného priamočarého směru v medzere o minimálnej šírke 8 mm a výške medzery podlá hrůbky materiálu, v oblasti dna spoja a citlivo a plynule před a najma v přiebehu horenia oblúka nastavitelným jednostranným vyosením z povodného priamočarého směru a táto reguláoia směru zváracieho drotu sa zabezpečuje počas zvárania mimo medzery.These disadvantages are largely eliminated by the invention. The principle and method of regulating the direction of the welding wire to a precise location in the welding joint during arc welding or arc welding, in particular in gas protection, is that the welding wire aa regulates from the initial rectilinear direction a gap of at least 8 mm material thicknesses, in the area of the joint bottom and sensitively and continuously before and in particular during the arc burning by adjustable one-sided offset from the flood rectilinear direction and this welding wire direction control is provided during the welding outside the gaps.
Spósob reguláoie směru zváracieho drotu podlá vynálezu sa zabezpečuje zváracím horákom, ktorého podstata podlá vynálezu spočívá v tom, že v otvore telesa zváracieho horáka je na jednej straně vsunuté priamočaré vedenie zváracieho drotu s regulačným elementom a na druhej straně je v otvore telesa zváracieho horáka upevněné pomocou upevňovacieho elementu kontaktně koncovka e pevným priamočarým vedením, na ktoré navazuje zakřivené vedenie zváracieho drotu. Přitom je priamočaré vedenie do pevného priamočarého vedenia v kontaktně j koncovke nasunuté otočné a preauvne, například pomocou závitu pre změnu vzdialenosti medzi výstupnou hranou priamočarého vedenia a bodom dotyku zváracieho drotu na zakrivenom vedení kontaktněj koncovky.The method of controlling the direction of the welding wire according to the invention is provided by a welding torch, which is based on the fact that in the opening of the welding torch body a linear guide of the welding wire with a control element is inserted. The fastening element of the contact terminal is a fixed rectilinear guide followed by a curved guide of the welding wire. In this case, the linear guide is rotatably and rigidly inserted into the fixed linear guide in the contact terminal, for example by means of a thread for changing the distance between the leading edge of the linear guide and the contact point of the welding wire on the curved guide of the contact terminal.

Značnú výhodu predatavuje i to, že při prípadnej poruche automatickej regulácie polohy zváracieho horáka v medzere je možnost ručného regulovania až do akončenia zvarového spoja.The welding torch according to the invention has several advantages, for example allowing the positioning of the welding seam in various positions of the epojus when welding in all positions on special joints β through a very narrow gap with a high joint height when welding rough materials. Hall allows positional! welders without changing the position of the welding torch in the gap from the bottom. It also has the advantage that the misalignment of the welding wire to the desired point in the apo can be controlled prior to welding, and this has been further controlled as required during arc burning manually or machine by means of an element located outside the gaps. Another significant advantage is that in the event of a failure of the automatic regulation of the position of the welding torch in the gap, there is a possibility of manual regulation until the end of the welding joint.
