Description

Vynález rieši mobilný skládací prípravok na skladanie zváraných I-profilov před zvarením vo vodorovnej polohe v sériovéj výrobě.SUMMARY OF THE INVENTION The present invention provides a mobile collapsible device for folding welded I-profiles prior to horizontal welding in series production.

Doteraz sa používá na skladanie zváraných I-profilov před zváraním stabilných skládacích prípravkov, ktoré sú rozMiesinené na nosnom ráme, alebo skládacích stolíc, u kterých skládaný I-profil prechádza cez válce stolice. Nevýhodou u stabilných skládacích prípravkov je ich velký počet vzhladom k dlžke skládaného I-profilu, pričom je pracná prestavovanie 3kladacích prípravkov na iný rozměr I-profilu. Nevýhodou u skládacích sto-, líc je konštrukčná zložitosť celého zariadenia a skutočnost, že pri tomto sposobe skladania je potřebná minimálně dvojnásobná dížka pracoviska vzWadom k celkovej dlžke skládaného I-profilu.It has hitherto been used for folding welded I-profiles before welding stable folding jigs that are dispersed on a support frame or folding stools in which the folded I-profile passes through the stool rollers. A disadvantage of the stable folding jigs is their large number in relation to the length of the folded I-profile, while it is laborious to convert the 3-folding jigs to a different dimension of the I-profile. A disadvantage of the folding tables is the structural complexity of the entire device and the fact that in this folding method at least twice the length of the work place is required in relation to the total length of the folded I-profile.

Podstatou mobilného skladacieho přípravku podlá vynálezu je následovně technické riešenie. K pojazdnému ráma.je pevne uchytený nosič, v ktorom je posuvné pomocou závěsných lcolies uložený priečailk, na ktorom je zavesený pomocou dvoch. přestaviteIných skrutiek strmen, ktorý má prestavitelný segment a pevný segment, v ktorom je uchytená tlačná hydraulická jednotka, pričom. k pojazdnému rámu sú přestavit el’ne uchytené dve přítlačné hydraulické jednotky.The mobile folding device according to the invention is based on the following technical solution. The carrier is fixed to the traveling frame, in which a partition is mounted sliding by means of hanging lcolies, on which it is suspended by means of two. the adjustable calliper bolts having an adjustable segment and a rigid segment in which the pressure hydraulic unit is mounted, wherein. Two pressure hydraulic units are attached to the mobile frame.

Horeuvedené nevýhody sú ódetránené u mobilného skladacieho přípravku podl'a vynálezu, u ktorého sú jednotlivé časti skládaného I-profilu uložené na podpěrách s pozdížny205 376The above-mentioned drawbacks are eliminated in the mobile folding device according to the invention, in which the individual parts of the folded I-profile are supported on supports with a longitudinal205 376

Predmet vynálezu je schématicky znázorněný na výkrese, kde na obr, 1 je jedno riedenie mobilného skladacieho přípravku v čelnom pohlade a na obr. 2 v bočnom pohlede.The object of the invention is schematically shown in the drawing, wherein in Fig. 1 is a front view of one dilution of a mobile collapsible jig; 2 in a side view.

K pojazdnému rámu 2» obr. 1 a obr. 2, ktorý je uložený pomocou kolies 11 na kolajnioiaoh 12. je pevne uchytený nosič 2, v ktorom je posuvné pomocou závěsných kolies 2 uložený priečnik 2, na ktorom je zavesený na skrutkách 2 strmeň 6 pomocou neotočných matic 11. ktorý má přestavitelný segment 2 zaistený čapom 16 v otvore 17 a pevný segment 8, v ktorom je uchytená tlačná hydraulická jednotka K pojazdnému rámu J sú prestavltelne uchytené dve přítlačné hydraulické jednotky JO, pričom pojazd rámu J, je buň strojný alebo ručný podlá celkovej zvolenej konštrukcie. Generátor tlakového média a regulačný rozvod nie sú zakreslené. Časti skládaného I-profilu 19 sa ukladajú na podpěry 13. ktoré sú opatřené pozdížnymi strediacimi vložkami 18. Skladanie je následovně. Najskór sa položí stojina na pozdížne strediace vložky 18 a potom sa vložia na podpěry 13 pásnice, ktoré sú držané nezakreslenými okrajovými stabilizačnými prvkami vo zvislej polohe. Potom sa prisunie na okraj skládaného I-profilu 19 prípravok a najskór sa přitlačí stojina poraocou přítlačných hydraulických jednotiek 10 k pozdížnym strediacim vložkám 18. čím nastane vystredenie stojiny voči pásniciam a potom následuje samotné stlačenie a zlicovanie pásnic so stojinou pomocou strmeňa j6 tlačnou hydraulickou jednotkou 2 ^a ich vzájomné stehovanie. Tieto operácie prebiehajú postupné pozdíž celého skládaného I-profilu 19« Rovnobežnosť pásnic je zabezpečená rovnobežnosťou opemej plochy 20 tlačnéj hydraulickéj jednotky 2 ^a opernej plochy 21 přestavíteTného segmentu 2» pričom vzájomnú kolmosť pásnic so stojinou vymedzuje kolmosť dosadaqej roviny pozdížnych strediacich vložiek 18 k rovinám opěrných plóoh 20 a 21. Prestavenie na iný rozměr I-profilu 19 sa prevádza přestavením prestaviteTného segmentu 2 na strmeni 6, nastavením výšky strmeňa 6 skrutkami 2 pomocou kíúk 15 voči osi I-profilu a výměnou pozdížnych strediacich vložiek 18. Letmým priečnya úchytením strmeňa 6 v ráme J pomocou závěsných kolies 2 umožněný volný pohyb rámu J pri presúvaní a súčasne sa do rámu J. nepřenášejí sily od etláčania pásnic so stojinou.To the traveling frame 2 »FIG. 1 and FIG. 2, which is supported by wheels 11 on rails 12, is fixedly fixed carrier 2, in which sliding by means of suspension wheels 2 is mounted crossbeam 2, on which the yoke 6 is suspended on screws 2 by non-rotating nuts 11, which has adjustable segment 2 secured By means of a pin 16 in the bore 17 and a fixed segment 8 in which the pressure hydraulic unit K is mounted. Two pressure hydraulic units 10 are clamped to the mobile frame J, the mobile of the frame J being mobile or manual according to the overall design chosen. The pressure medium generator and the control system are not shown. The portions of the folded I-profile 19 are placed on supports 13 which are provided with longitudinal centering inserts 18. The folding is as follows. First, the web is placed on the longitudinal centering inserts 18 and then placed on the flange supports 13, which are held by the unstained edge stabilizing elements in a vertical position. The web is then pushed to the edge of the folded I-profile 19 and the web is first pressed by the thrust hydraulic units 10 to the longitudinal centering inserts 18, centering the web against the flanges, followed by the compression and flanging of webs with the yoke. ^and their mutual migration. These operations take place gradually along the entire folded I-profile 19 «The parallelism of the flanges is ensured by the parallelism of the abutment surface 20 of the pressure hydraulic unit 2 ^{and the} abutment surface 21 of the adjusting segment 2». 20 and 21. Adjustment to a different dimension of the I-profile 19 is accomplished by adjusting the adjustable segment 2 on the yoke 6, adjusting the height of the yoke 6 with screws 2 using the keys 15 relative to the I-profile axis and replacing the longitudinal centering inserts 18. By means of the suspension wheels 2, the frame J can be moved freely when it is moved and at the same time no forces are transmitted to the frame J by pushing the flanges with the web.
