Description

Piekļaujošos cauruļu salodešanas paņēmiens Izgudrojuma aprakstsBACKGROUND OF THE INVENTION Description of the Invention

Izgudrojums attiecas uz lodēšanas jomu un to var izmantot cauruļveida konstrukciju, piemēram, dvieļu žāvētāju, izgatavošanai.The invention relates to the field of soldering and can be used for the manufacture of tubular structures such as towel warmers.

Ir zināms piekļaujošos cauruļu salodēšanas paņēmiens, saskaņā ar kuru, lai orientētu piekļaujošās caurules, uz galvenās caurules izpilda punktveida iepresējumus (patentpieteikums RU 2001110903; SKI B23K1/00; 2003/. Tomēr šāds paņēmiens der tikai teleskopiskiem savienojumiem, kad caurule ar mazāku diametru ir orientēta pēc lielākās caurules iekšējā diametra.A method of soldering tube clamps is known, according to which pointing dies are performed on the main pipe in order to orientate the clamping pipes (patent application RU 2001110903; SKI B23K1 / 00; 2003 /. However, this method is only suitable for telescopic connections when the smaller diameter pipe is oriented by the inside diameter of the largest pipe.

Ir zināms arī piekļaujošos cauruļu salodēšanas paņēmiens, saskaņā ar kuru to savstarpējai orientācijai izmanto ieliktni /patents RU 2240909; SKI B23K1/00; 2002/. Šī paņēmiena trūkums ir tas, ka to var pielietot tikai caurulēm uz kopējās ass.Also known is the method of soldering the overlapping tubes, according to which a liner / patent RU 2240909 is used for their mutual orientation; SKI B23K1 / 00; 2002 /. The disadvantage of this technique is that it can only be applied to pipes on the common axis.

Vistuvāk šim izgudrojumam pēc tehniskās būtības un sasniedzamā rezultāta ir piekļaujošos cauruļu salodēšanas paņēmiens, saskaņā ar kuru galvenajā detaļā, piemēram, caurulē, piekļaujošās caurules atrašanās vietā izveido caurumu, ap kuru gredzenveidā izvieto lodi, pēc tam uzstāda piekļaujošos cauruli un to nofiksē uz vienas ass ar galvenajā caurulē izveidoto caurumu un pēc tam izpilda lodēšanu /PCT pieteikuma publikācija WO 2000504663: SKI F16L41/08 A1; 2005/. Šī paņēmiena, kas izvēlēts par prototipu, trūkums ir sekojošs: lai piekļaujošos cauruli fiksētu attiecībā pret minēto caurumu, kurš izveidots galvenajā caurulē, fiksācijai tiek izmantota vara šķīvjveida paplāksne, kura pasliktina lodējuma kvalitāti, tā kā uzņem sevī daļu siltuma un lodmateriāla, kurš ir vajadzīgs galvenā savienojuma veidošanai. Rezultātā var izveidoties porains, neblīvs un nestiprs savienojums vēl jo vairāk tāpēc, ka šis process notiek slēgtā vidē un to nav iespējams kontrolēt.Closest to the present invention, in terms of its technical nature and the result to be achieved, is a method of soldering the adjoining pipe, whereby a key is formed at the location of the adjoining pipe by a circular ball, then mounted on the adjoining pipe and a hole formed in the main tube and subsequently soldered / PCT Application Publication WO 2000504663: SKI F16L41 / 08 A1; 2005 /. The disadvantage of this method, selected as a prototype, is that a copper plate washer is used to fix the overlapping tube to said hole formed in the main tube, which degrades the solder quality as it absorbs some of the heat and solder needed for the main connection. The result is a porous, non-dense, and loose connection, all the more so because the process is confined and cannot be controlled.

Piedāvātā tehniskā risinājuma mērķis ir paaugstināt lodējuma kvalitāti. Tas tiek sasniegts tādējādi, ka, salīdzinot ar prototipā aprakstīto lodēšanas paņēmienu, saskaņā ar kuru galvenajā caurulē piekļaujošās caurules atrašanās vietā izveido caurumu, ap kuru gredzenveidā izvieto lodi, pēc tam uzstāda piekļaujošos cauruli un to nofiksē uz vienas ass ar galvenajā caurulē izveidoto caurumu, bet pēc tam izpilda lodēšanu, šai izgudrojumā lodi formē apkārt pielodējamai caurulei pa iekšējo diametru, cauruma pretējās malās galvenajā caurulē izgriež lapiņas un tās atliec līdz lodes gredzena iekšējam diametram, pēc tam uz lapiņām uzmauc lodi, uz tās uzmauc pielodējamo cauruli un izpilda lodēšanu, savienojumu karsējot, kamēr lode izkūst un aizpilda cauruļu savienojumu.The purpose of the proposed technical solution is to increase the quality of the solder. This is accomplished by comparing the soldering method described in the prototype, which is to create an annular hole at the location of the inclined tube in the main tube, then install the overlapping tube and fix it on the same axis with the hole in the main tube, but then soldering, in this invention, the ball is formed around an internal diameter of the soldering tube, the sheets are cut at the opposite sides of the hole in the main tube and folded to the inside diameter of the ball ring, then the ball is applied to the solder and soldered while the ball melts and fills the pipe joint.

Piedāvātais tehniskais risinājums ir paskaidrots pievienotajos rasējumos, kur:The proposed technical solution is explained in the accompanying drawings, where:

Fig.1 ir parādīts savienojuma vietas gareniskais greizums pēc detaļu komplektācijas pirms lodēšanas;Fig. 1 is a longitudinal distortion of a joint after assembly of parts prior to soldering;

Lodēšanas process saskaņā ar izgudrojumu notiek sekojošā secībā: galvenajā caurulē (1) piekļaujošās caurules (2) pielodēšanas vietā izurbj caurumu (3): lodi (4) izveido gredzenveidā, pie kam šī gredzena ārējais diametrs ir vienāds ar pielodējamās caurules (2) iekšējo diametru; cauruma /urbuma/ (3) pretējās malās izgriež lapiņas (5) un tās atliec vertikālā stāvoklī, pie kam iegriezuma dziļumu izvēlas tādu, lai pēc atlocīšanas lapiņas (5) atrastos lodmateriāla gredzena (4) iekšējā diametra attālumā; pēc tam uz atliektajām lapiņām (5) uzmauc gredzennveidā izveidoto lodi (4), bet uz tās - pielodējamo cauruli (2), kā rezultātā lapiņas (5) nofiksē lodes gredzenu (4), bet šis gredzens savukārt nofiksē piekļaujošos cauruli (2); pēc iepriekš minēto darbību izpildes veic visas konstrukcijas kopējo karsēšanu, kuras rezultātā viss lodmateriāls nonāk cauruju savienojuma vietā.The soldering process according to the invention proceeds in the following order: Drill a hole (3) in the soldering tube (2) in the main pipe (1): the ball (4) is annular, the outer diameter of this ring being equal to the inner diameter of the soldering pipe (2) ; cutting the sheets (5) at opposite sides of the hole / bore / (3) and tilting them into an upright position, wherein the depth of cut is selected such that, after folding, the sheets (5) are at a distance from the inside diameter of the solder ring (4); then, on the folded leaves (5), a ring-shaped ball (4) and a solder tube (2) are applied thereto, whereby the leaves (5) lock the ball ring (4) and this ring in turn fixes the adjoining tube (2); after performing the above steps, a common heating of the whole structure is carried out, whereby all solder enters the pipe joint.

Piedāvātā paņēmiena izmēģinājumi pilnībā apstiprināja tā efektivitāti un izvirzītā mērķa sasniegšanu. Izmēģinājuma procesā pie vara caurules ar diametru 28 mm un sienu biezumu 1 mm tika pielodēta vara caurule ar diametru 22 mm un ar sienu biezumu 1 mm. Galvenajā caurulē tika izurbts caurums ar diametru 10 mm. No lodmateriāla stieņa ar diametru 2 mm tika izveidota lodeExperiments on the proposed technique fully confirmed its effectiveness and the achievement of its objective. During the trial, a copper tube with a diameter of 28 mm and a wall thickness of 1 mm was soldered to a copper tube with a diameter of 22 mm and a wall thickness of 1 mm. A hole with a diameter of 10 mm was drilled in the main pipe. A ball of 2 mm diameter was formed into a ball

J gredzena veidā ar ārējo diametru 22 mm, kas atbilda pielodējamās caurules iekšējam diametram. Pēc tam izurbtā cauruma malās ar speciālu instrumentu tika izgrieztas lapiņas 3 mm dziļumā un tās tika atliektas vertikālā stāvoklī. Pēc tam uz atliektām lapiņām tika uzlikts lodes gredzens, bet uz tā savukārt tika nostiprināta pielodējamā caurule. Rezultātā notika blīva lodes gredzena fiksācija uz galvenās caurules. Visbeidzot ar lodējamā aparāta liesmu tika karsēta savienojuma vieta un izpildīta lodēšana. Lai pārbaudītu savienojuma blīvumu un izturību, tika padots saspiests gaiss 6 atm. Izmēģinājuma laikā lodējuma vieta netika sagrauta, bet sagraušana notika pa galveno materiālu, kas neizturēja spiedienu aiz cauruļu salaides vietas.In the form of a J-ring with an outer diameter of 22 mm, corresponding to the inner diameter of the solder pipe. The leaves were then cut to a depth of 3 mm with a special tool at the edges of the drilled hole and then folded upright. Afterwards, a bullet ring was placed on the folded leaves, and the soldering tube was then secured to it. As a result, a dense ball ring was fixed on the main tube. Finally, the soldering iron flame was used to heat the joint and solder. Compressed air was supplied at 6 atm to check the connection density and durability. During the trial, the soldering site was not destroyed, but the main material, which did not withstand pressure behind the pipe joint, was destroyed.

Tādējādi piedāvātais paņēmiens dod sekojošas priekšrocības, salīdzinot ar prototipu:Thus, the proposed method offers the following advantages over the prototype:

- samazina materiāla karsēšanas laiku lodēšanas vietā uz materiāla samazināšanas rēķina,- reduce the heating time of the material at the soldering station at the expense of material reduction,

- pie vienāda lodmateriāla patēriņa palielina lodmateriāla daudzumu, kas tiek izmantots paša savienojuma veidošanai,- increase, at the same consumption of solder, the amount of solder used to form the joint itself,

- izslēdz nesalodēšanas iespēju lodmaterīāla trūkuma dēļ savienojuma veidošanas vietā, tā kā viss lodmateriāls paliek tieši savienojuma vietā;- eliminates the possibility of soldering due to the lack of solder at the joint, since all solder remains directly at the joint;

- paaugstina salodētā savienojuma kvalitāti.- increases the quality of the soldered connection.
