Description
Изобретение относитс к сварке и касаетс устройств дл сварки полотнищ на флюсовой подушке.The invention relates to welding and relates to devices for welding sheets on a flux cushion.
Известен стенд дл сварки полотнищ, содержащий металлическую балку, на которой расположена флюсова подушка.A stand for welding panels is known, containing a metal beam on which a flux cushion is located.
Однако этот стенд не обеспечивает равномерный поджим кромок листов свариваемого полотнища к флюсовой подушке, чтоведет к получению некачественного сварного соединени .However, this stand does not provide uniform pressing of the edges of the sheets of the sheet being welded to the flux cushion, which leads to a poor-quality welded joint.
Цель изобретени - повысить точность сборки за счет раст жени кромок листов свариваемого полотнища путем прикреплени их к балке.The purpose of the invention is to improve the assembly accuracy by stretching the edges of sheets of the sheet being welded by attaching them to the beam.
Дл этого металлическа балка снабжена нагревательными элементами, встроенными в пазы, выполненные на поверхности балки по всей ее длине.For this, the metal beam is provided with heating elements embedded in grooves made on the surface of the beam along its entire length.
На фиг. 1 изображен предлагаемый стендна фиг. 2 - часть стенда со свариваемым полотнищем и балкой, в плане.FIG. 1 shows the proposed poster of FIG. 2 - part of the stand with the welded panel and the beam, in plan.
тельные элементы 3 (например, электроспирали ). Балка выполнена из жаропрочной стали, имеющей повышенную прочность при высокой температуре, и может перемещатьс на роликах 4 поперек стенда до совмещени со свариваемым стыком. Над балкой 2 располагаетс флюсова подушка 5, установленна с возможностью вертикального перемещени с помощью механизма 6.body elements 3 (for example, electrospirals). The beam is made of heat-resistant steel having increased strength at high temperature, and can be moved on rollers 4 across the stand to align with the welded joint. Above the beam 2 there is a flux cushion 5 installed with the possibility of vertical movement by means of the mechanism 6.
Промежуточные планки 7 служат дл прикреплени сваркой к балке 2 свариваемых листов 8. Планки готов тс из того же металла, что и листы 8, и приворачиваютс к балке 2 вкладыщами 9 из того же металла. Дл увеличени усили раст жени толщина промежуточных планок 7 выбираетс больше толщины свариваемых листов 8, а планки подогреваютс до 600 - 800°С после их приварки к свариваемым листам 8 и до приварки к балке 2.The intermediate strips 7 serve to attach the welded to the beam 2 of the welded sheets 8. The strips are made of the same metal as the sheets 8, and are screwed to the beam 2 by inserts 9 of the same metal. In order to increase the stretching force, the thickness of the intermediate strips 7 is chosen greater than the thickness of the sheets 8 to be welded, and the strips are heated to 600-800 ° C after they are welded to the sheets 8 to be welded and before welding to the beam 2.
Затем балка 2 нагреваетс с помощью нагревательных элементов 3 и ее тепловое расщирение вызывает образование в свариваемых кромках напр жений раст жени , равных пределу текучести.Then, the beam 2 is heated with the help of heating elements 3 and its thermal expansion causes the formation of tensile stresses in the welded edges equal to the yield strength.
