Zariadenie pre montáž zvarovaných nosníkov profilov I s rozdielnou výškou stojiny, které pozostáva z pevného rámu s vodorovnou opracovanou plochou pre ustavenie a upnutie stojiny nosníka a dosedacej plochy pevného rámu pre uloženie hornej a dolnej pásnice v rovinnom stave a otočných hydraulických upiniek k upnutiu stojiny nosníka. Na pevnom ráme sú upevněné hydraulické válce, opatřené prizmami pre tvarovanie hornej a dolnej pásnice postupovým ohybom za studená. Zariadenie podlá vynálezu je možno s výhodou využit zvlášf v stavbě kolejových vozidiel, připadne při stavbě nosných konštrukcií čestných vozidiel a ich prívesov.A device for mounting welded I-beams with different heights consisting of a rigid frame with a horizontal machined surface for aligning and clamping the beam web and a fixed frame bearing surface for supporting the upper and lower flange in a flat condition and rotating hydraulic clamps for clamping the beam web. Hydraulic cylinders are mounted on a rigid frame, provided with prisms for shaping the upper and lower flanges by cold bending. The device according to the invention can advantageously be used in particular in the construction of rail vehicles or in the construction of load-bearing structures of honor vehicles and their trailers.

Vynález sa týká zariadenia pre montáž zvarovaných nosníkov profilu I s rozdielnou výškou stojiny bez predohýbania hlavně pri stavbě kolejových vozidiel.BACKGROUND OF THE INVENTION The present invention relates to a device for mounting welded I-beams with different web heights without bending, especially in the construction of rail vehicles.

Doposial' pri montáži nosníkov profilu I s rozdielnou výškou stojiny bolo potřebné horná a dolnú pásnicu predohýbať na lise. Pri veíkom poloměre ohybu pásnice a prierezovom přechode stojiny sa predohýbanie prakticky nedá prevádzať na lisoch běžného prevedenia z důsledku obmedzeného zdvihu. Z toho dovodu sa predohýbanie prevádzalo na lise špeciálne upravenom pre daný tvar pásnic za tepla v zápustke pozostávajúcej z patrice a matrice.Until now, when installing the I-beams with different web heights, it was necessary to bend the upper and lower flange on the press. With a large flange bend radius and cross-sectional web transition, the bending is virtually impossible to perform on conventional presses due to the limited stroke. For this reason, the bending was carried out on a press specially adapted for the shape of the hot flanges in a die consisting of a cap and a die.

Uvedené nedostatky odstraňuje zariadenie podlá vynálezu, ktorého podstatou je, že pozostáva z pevného rámu s vodorovnou opracovanou plochou pre ustavenie a upnutie stojiny nosníka a dosadacej plochy pevného rámu pre uloženie hornej a dolnej pásnice v rovinnom stave a otočných hydraulických upiniek k upnutiu stojiny nosníka. Na pevnom ráme sú upevněné hydraulické válce, opatřené prizmami pre tvarovania hornej a dolnej pásnice postupovým ohybom za studená.The above-mentioned drawbacks are eliminated by the device according to the invention, which consists of a fixed frame with a horizontally machined surface for aligning and clamping the web of the beam and a bearing surface of the rigid frame for supporting the upper and lower flange in planar condition. Hydraulic cylinders are mounted on a rigid frame, provided with prisms for shaping the upper and lower flanges by cold bending.

Hlavnou výhodou zariadenia spočívá v tom, že odpadá prácne prehýbanie pásnic v špeciálnom lise za tepla v zápustke, medzioperačná přeprava dielcov k návaznému montážnemu přípravku, kde sa montáž nosníka prevádzala ručně pomocou skrutiek. Takto prevádzaná montáž nosníkov profilov I nezaručovala přesné kopírovanie tvaru stojiny a vzniklé medzery medzi stojinami a pásnicami sa museli ručně predvárať, nakol'ko automatické zváranie vylučuje akúkofvek možnost medzery. V predmetnom hydraulickom zariadení, kde matricu tvoří stojina, horná a dolná pásnica presne kopíruje tvar stojiny, čím sa vylúči vznik medzery a takto zmontovaný nosník je připravený pre automatické zvarovanie.The main advantage of the device is that there is no laborious bending of the flanges in a special hot press in the die, in-process transport of the parts to the subsequent assembly jig, where the assembly of the beam was carried out manually by means of screws. The mounting of the I-beams thus carried out did not guarantee accurate copying of the web shape and the resulting gaps between the webs and the flanges had to be manually pre-welded, since automatic welding eliminates any possibility of a gap. In the present hydraulic device, where the web is formed by the web, the upper and lower flanges accurately follow the web shape, thus avoiding the formation of a gap, and the thus assembled beam is ready for automatic welding.

Na pripojenom výkrese je znázorněný příklad prevedenia zariadenia na montáž tvarovaných nosníkov podlá vynálezu, kde na obr. 1 je znázorněný jeho půdorys. Obr. 2 představuje sposob uloženia stojiny nosníka na opracovanej vodorovnej ploché pevného rámu .a směr posobenia tlačných priziem kopírujúcich tvar stojiny nosníka.The attached drawing shows an example of an embodiment of a device for assembling shaped beams according to the invention, in which FIG. 1 is a plan view thereof. Fig. 2 illustrates a method of mounting a web of a beam on a machined horizontal flat rigid frame and the direction of operation of the press yarns following the shape of the web of a beam.

Do zariadenia pozostávajúceho z pevného rámu zváranej konštrukcie 1 sa vloží stojina nosníka 19, ustaví do vychodzej polohy a upne pomocou hydraulických otočných úpiniek 14 prostrednictvom ručného rozvádzača 16. Následné sa vloží pásnica horná 20 a pásnica dolná 21, ktorá sa ustaví pomocou montážnych dorazov 15. Tvarovat sa začína postupovým ohybom prostrednictvom skupinového ručného rozvádzača 17, ktorého pákou 24 sa uvedu do činnosti hydraulické válce 9 a 10, pákou 25 sa uvedú do činnosti válce 8, 11 a nakoniec pákou 28 sa uvedú do činnosti válce 12, 13, ktoré dotlačia pásnice na konečný tvar nosníka. Tvarovacie prizmyIn the apparatus consisting of a rigid frame of the welded structure 1, the web of the beam 19 is inserted, brought to the starting position and clamped by means of the hydraulic rotary clamps 14 by means of the manual distributor 16. Subsequently, the upper flange 20 and lower flange 21 are inserted. Shaping begins with a progressive bending by means of a grouped manual distributor 17 whose lever 24 actuates the hydraulic cylinders 9 and 10, lever 25 actuates the cylinders 8, 11 and finally the lever 28 actuates the cylinders 12, 13 which press the flanges. to the final shape of the beam. Shaping prisms

2, 3, 4, 5 sú presne vedené vodiacimi lištami S a 7. Zdrojom tlakového oleja pre všetky hydraulické válce a úpinky je hydraulický agregát 18. Po doformovaní na konečný tvar nosníka sa prevedie stehový zvar, hydraulické válce 8, 9, 10, 11, 12 prostrednictvom ručných rozvádzačov 16, 17 vrátia prizmy 2,2, 3, 4, 5 are precisely guided by guide rails S and 7. The source of the pressure oil for all hydraulic cylinders and clamps is the hydraulic aggregate 18. After being formed into the final beam shape, the stitch weld is performed, hydraulic cylinders 8, 9, 10, 11 , 12 by means of manual distributors 16, 17 returns prisms 2,

3, 4, 5 do východzej polohy, otočné úpinky 14 uvolnia stojinu 19, zmontovaný nosník sa pomocou zdvihacieho zariadenia vyberie von a presunie na skládku, respektive do zváracieho zariadenia.3, 4, 5 to the starting position, the rotary clamps 14 release the web 19, the assembled beam is removed by means of a lifting device and moved to the landfill or to the welding device, respectively.
