Abstract

Sposób niskotemperaturowego łączenia rur zwłaszcza ocynkowanych, wykorzystywany do bezodpadowego łączenia słupków i konstrukcji wsporczych do montażu znaków i tablic drogowych, drogowych barier ochronnych, poręczy i wszystkich innych elementów wykonanych z profili o przekroju kołowym a spełniających określone wymagania wytrzymałościowe, w którym w pierwszej kolejności odkształca się plastyczne poprzez przewężenie element (2) o długości (L1) na odcinku długości (L2), przy pomocy prasy o sile nacisku 1500 - 3000 kN, przy czym długość odkształcanego odcinka L2 stanowi 1/20 - 40 długości (L1), zaś średnica zewnętrzna O1 elementu (1) odkształcana jest o grubość ścianki elementu G + 1 mm, do średnicy wewnętrznej elementu (2) O2 - 1 mm, kolejno element (1) pasowany jest ciasno z elementem (2), poprzez umieszczenie odkształconego odcinka L2 w średnicy wewnętrznej O2 elementu (1) następnie element (1) poddaje się na długości L3 ? L2 odkształceniu poprzez przewężenie na prasie z siłą 1500 - 3000 kN, o wartość G, do średnicy (O3).A method of low-temperature joining of pipes, especially galvanized, used for the zero-waste joining of posts and supporting structures for the installation of road signs and boards, road safety barriers, handrails and all other elements made of circular cross-section profiles that meet specific strength requirements, in which it first deforms plastic by narrowing an element (2) with a length (L1) over a length (L2), using a press with a pressure force of 1500 - 3000 kN, where the length of the deformed section L2 is 1/20 - 40 length (L1), and the outer diameter O1 of the element (1) is deformed by the wall thickness of the element G + 1 mm, to the internal diameter of the element (2) O2 - 1 mm, successively the element (1) fits tightly with the element (2) by placing the deformed segment L2 in the internal diameter O2 of the element (1) then the element (1) is subjected to the length L3? L2 deformation by narrowing on the press with a force of 1500 - 3000 kN, by the value of G, to diameter (O3).
