Description
уплотнение 6, токоподво щую встав . ку 7 и тройной )шдкий сплав 8 галлийиндий-олово , причем на поверхност х 9 шпиндел и токоподвод щей вставки, соприкасаюишхс 6 жидким сплавом, выполнено покрытие из галли , инди , или олова с подслоем меди. Покрытие выполн етс путем эле кт7 рохимического нанесени сло медй , вжигани ее в вакууме и последующего лужени медных поверхностей галлием, индием или оповом.Причем количество металлов, вход ащх в покрытие,должно быть таково., чтобы раствор сь в тройном жидком спла- . ве, оно не мен ло температуру его кристаллизации. При соприкосновении покрытых поверхностей с тройным жидким сплавом -часть покрыти раствор етс в нем, а оставшийс тонкий слой обеспечивает смачивание поверхностей шпиндел и токоподвод щей вставкиseal 6, current-carrying stand. 7 and a triple alloy of 8 gallium indium tin, and on the surfaces of 9 spindles and the current-carrying insert, in contact with 6 liquid alloy, a coating of gallium, indium, or tin with a copper underlayer was made. The coating is made by electrically applying a chemical layer of copper, burning it in vacuum and subsequent tinning of copper surfaces with gallium, indium or opium. Moreover, the amount of metals entering the coating must be such that the solution in a triple liquid melt. It did not change its crystallization temperature. When the coated surfaces are in contact with the triple liquid alloy, a part of the coating dissolves in it, and the remaining thin layer ensures the wetting of the surfaces of the spindle and the current-carrying insert.
Таким образом, наличие указанного покрыти на поверхност х шпиндел и токоподвод щей вставки позвол ет значительно уменьшить омическое сопротивление переходного контакаа тверДЛй металл - тройной жидкий сплав уменьшать потери мощности и устранить повышенный нагрев устройства при прохождении сварочного тока.Thus, the presence of the specified coating on the surfaces of the spindle and the current-carrying insert makes it possible to significantly reduce the ohmic resistance of the transitional contact metal — a ternary liquid alloy to reduce the power loss and eliminate the increased heating of the device during the passage of the welding current.
Устройство работает следующим образом.The device works as follows.
К токоподвод щей вставке 7 подключаетс шина электрической цепи сварочной машины. Под сварочным роп ком с равномерной скоростью переia T свариваемое изделие, и онA busbar electrical circuit of the welding machine is connected to the current-carrying insert 7. Under the welding rop with a uniform speed, the welded product is repainted, and it
легко обкатываетс по свариваемой поверхности без проскальзывани .При этом по электрической цепи: гокоподвод ща вставка 7 жидкий сплав 8 шпиндель 2 - сварочный ролик 3-изделие протекает сварочный ток. При выходе издели из-под ролика последний перестает вращатьс , а электрическа цепь размыкаетс .easily rolls on the surface to be welded without slipping. At the same time along the electric circuit: gokodvod insert 7 liquid alloy 8 spindle 2 - welding roller 3-product welding current flows. When the product emerges from under the roller, the latter stops rotating, and the electric circuit is opened.
