Uprawniony z patentu: Experimentalnoe Proizvodstwo po Razrabotke i Izgotovleniju Sredstv Mekhanizatsii v Stroitel- stve Tresta „Kievorgstroi", Kijów (Zwiazek So¬ cjalistycznych Republik Radzieckich) Urzadzenie do spawania termoplastycznych materialów arkuszowych, zwlaszcza linoleum i Wynalazek dotyczy urzadzenia do spawania ter¬ moplastycznych materialów arkuszowych, zwla¬ szcza linoleum i moze byc z powodzeniem wyko¬ rzystany do spawania arkuszy wymienionych wy¬ zej materialów zarówno bezposrednio na obiek¬ tach budowlanych jak tez i w warunkach fabry¬ cznych.Znane sa powszechnie urzadzenia do spawania arikuiszy materialów termoplastycznych przy uzyciu materialu dodatkowego w postaci sznura, uklada¬ nego do polaczenia na styk spawanych arkuszy i obtapianego w nim nagirzanyim ^gazem jednocze¬ snie z obtapianiem krawedzi ispawanych.Takie urzadzenia zawieraja zwykle pusty korpus ogrzewany, do którego doprowadzany jest gaz i polaczona z korpusem glowice spawarki dla do¬ prowadzenia nagrzanego gazu do strefy spawania, do której przymlocowany jest walec doprowadza¬ jacy sznur materialu dodatkowego do polaczenia stykowego arikuszy i wygladzajacy spawany szew.Dla otrzymania sizwa spawanego dobrej jakosci, krawedzie spawanych atfkuszy powinny byc przy¬ gotowane w ten sposób, aby przy ukladaniu tych arkuszy na sitylk dodatkowego materialu utworzyl sie miedzy mimi rowek dla ulozenia szinura, profil którego odpowiadalby profilowi sznura.W dalszym ciagu opisu ten proces przygotowa¬ nia krawedzi arkuszy do spawania bedzie zwany wyfkoniczeniem krawedzi. 10 25 Znane urzadzenia do spawania arkuszowych ma¬ terialów termoplastycznych nie gwarantuje wy¬ konczenia krawedzi arkuszy spawanych. Czynnosci te dokonuje sie przy pomocy recznych narzedzi takich jak rylce, noze i tym podobnych, co zna¬ cznie zwieksza pracochlonnosc spawania.Celem iwynalazku jest usuniecie wymienionej wady i stworzenie urzadzenia do spawania termo¬ plastycznych materialów arkuszowych, zwlaszcza linoleum, które pazwalaloby bezposrednio w pro¬ cesie spawania tworzyc rowek do ukladania ma¬ terialu dodatkowego, zapewniajac przez to samo obnizenie pracochlonnosci procesu wykonczenia krawedzi spawanych ankuszy i ulepszenie jakosci spawanego szwa.Cel ten zostal osiagniety dzieki temu, ze urza¬ dzenie do spawania termoplastycznych materialów arkuszowych, zwlaszcza linoleum, przy uzyciu do¬ datkowego materialu, obtapianego przez gaz na¬ grzany, posiadajace pusty korpus, do którego do¬ prowadza sie ogrzewajacy gaz i polaczona z kor¬ pusem glowice spawarki dla doprowadzenia na¬ grzanego gazu do strefy spawania, zawiera umie¬ szczony przed strefa spawania przyrzad do wykon¬ czenia krawedzi arkuszy spawanych, majacy wpro¬ wadzona do wneki, po której przechodzi nagrzany gaz, dysze doprowadzajaca gaz do spawanych kra¬ wedzi bezposrednio przed strefa spawania i umo¬ cowany na korpusie bezposrednio za dysza walek majacy na cylindrycznej powierzchni opasujacy 80 85780 3 wystep wchodzacy w polozeniu roboczym w styk spawanych arkuszy i tworzacy w rozgrzanym po¬ laczeniu stykowym rowek do ukladania materialu dodatkowego.Za pomoca dyszy, wprowadzonej do wneki glo¬ wicy spawarki luib korpusu, nagrzany gaz dopro¬ wadza sie do krawedzi spawanych arkuszy bez¬ posrednio przed strefa spawania, przy czym kra- wejtizie rozgrzewajja sie do stanu ciagliwego.Przy przemieszczeniu urzadzenia podczas spa¬ wania, walek umieszczony bezposrednio za dysza (w kierunku ruchu urzadzenia), swym wysttepem opasujacym, wchodzacym w styk arkuszy spawa¬ nych, tworzy w rozgrzanych arkuszach rowek za¬ danego ksztaltu. Ksztaljt rowka zalezy od ksztaltu przekroju poprzecznego) dodatkowego materialu i od rodzaiju spawanego materialu.Obecnosc przyrzadu do wykonczenia krawedzi w urzadzeniu do spawania zapewnia jednoczesne utworzenie rowlka dla materialu dodatkowego i spawanie arkuszy, czyli polaczenie tych operacji, co znacznie obniza pracochlonnosc procesu spawa¬ nia arkuszy.Przy spawaniu arkuszy z materialem dodatko¬ wym, ukladanym do utworzonego w opisany po¬ wyzej sposób rowka, jakosc szwu staje sie zna¬ cznie lepsza.Dla lepszego zrozumienia istoty wynalazku urza¬ dzenie jest przedstawione w przykladowym wyko¬ naniu na rysunku, na którym fig. 1 przedstawia urzajdzende do spawania arkuszy w widoku z boku z czesciowym przelkrojem, fig. 2 — fragment urzadzenia w przekroju wzdluz linii II — II na fig. 1 uwidaczniajacy walek.Urzadzenie sklada sie z korpusu 1, z którym z jednej strony polaczona jest glowica 2 spawarki z walkiem 3 prowadzacym sznur 4 materialu do¬ datkowego dla polaczenia stykowego arkuszy 5 li¬ noleum, a z drugiej strony elektryczny grzejnik 6 z wentylatorem 7 i rekojescia 8.Do korpusu 1 przed strefa spawania przymoco¬ wany jest przyrzad 9 do wykonczenia krawedzi spawanych arkuszy 5. Przyrzad 9 zawiera dysze 10, wprowadzona do wnejki korpusu 1 i walek 11, zamocowany na jednym koncu dzwigni 12, drugi koniec której za pomoca sprezyny 13 polaczony jest z korpusem 1.Dzwignia 12 podwieszona jest na wsporniku 14 do korpusu 1. Walek 11 na cylindrycznej powierz¬ chna ma opasujacy wystep 15, profil którego odpo¬ wiadaprofilowi przeJtoroju poprzecznego sznura ma¬ terialu dodatkowego. 4 Opisane urzadzenie pracuje w nastepujacy spo¬ sób.Urzadzenie ustawia sie na ulozonych uprzednio na podlodze arkuszy przeznaczonych do zespawa- 5 nia na przyklad linoleum, w ten sposób aby pro¬ wadzaca rolka 16 i walek 11 stykaly sie z arkusza¬ mi spawanymi.Sznur materialu dodatkowego zaklada sie po¬ przez prowadzace walki 17 pod walek 3 i wlacza io sie elektryczny silnik 6 wentylatora 7, doprowa¬ dzajacy powietrze do (korpusu 1 urzadzenia, w któ¬ rym przewidziane sa elektryczne grzejnilki 18.Powietrze we wnece 19 korpusu nagrzane do terriperatury spawania, poprzez glowice 2 spawarki 15 nakierowuje sie do strefy spawania, a przez dysze 10 doprowadza sie bezposrednio przed strefe spa¬ wania do krawedzi spawanych j nagrzewa je do stanu cdajgMwego.Przy przemieszczaniu urzadzenia w kierunku 20 zgodnym ze strzalka A, walek 11 naciskajac wy¬ stepem 15 na rozgrzane krawedzie, deformuje je tworzac w polaczeniu stykowym rowek, którego profil odpowiada profilowi wystepu 15.Jednoczesnie podczas przemieszczenia urzadze- 25 nia odbywa sie ukladanie sznura 4 materialu do¬ datkowego do uformowanego rowka, spawanie krawedzi arkuszy przez obtapianie scianek wpustu i sznura materialu dodatkowego, jak równiez wy¬ gladzanie tworzacego sie spawanego szwa przez 30 walek 3.Dla utworzenia rowka o odmiennym profilu przewidziany jest komplet walków 11 o róznych wystepach 15. 35 PL PL
