Abstract
Изобретение относится к сварке и наплавке и может найти применение при восстановлении изношенных частей деталей типа тел вращения, в частности бурильных труб. Устройство для восстановления наплавной бурильной трубы (1) содержит узлы хранения, подачи и перегрузки трубы (1), опоры для размещения трубы (1), привод ее вращения (6), узел подачи воздуха (29) внутрь трубы (1), кольца (30) для охлаждения торцов трубы (1) и удержания флюса (24), приспособления для термостатирования мест наплавки, размещенную в наплавочной головке (17) группу электродов (19) для наплавки ниппельной части трубы (10), запитанную от одного источника электрического тока (15), и группу электродов (19) для наплавки муфтовой части трубы (9), размещенную в другой наплавочной головке и запитанную от второго источника электрического тока, при этом каждая наплавочная головка установлена с возможностью линейного и углового отклонения от «зенита» и продольного горизонтального и вертикального ее перемещения и связана с механизмом подачи (18) электродов (19) в наплавочную головку (17) и флюсобункером (23), опоры для размещения трубы (1) выполнены токопроводящими с подключением «плюса» на трубу (1), а «минуса» - на электроды (19), в каждой наплавочной головке электроды (19) установлены в ряд параллельно образующей трубы (1) с возможностью изменения расстояния между ними, а узел продольного перемещения электродов (19) выполнен с возможностью одновременной подачи флюса (24) в зону наплавки.The invention relates to welding and welding and can be used in the recovery of worn parts of parts such as rotation bodies, in particular drill pipes. The device for restoring the floating drill pipe (1) contains storage, supply and overloading units for the pipe (1), supports for placing the pipe (1), driving it to rotate (6), air supply unit (29) to the inside of the pipe (1), ring ( 30) to cool the ends of the pipe (1) and hold the flux (24), devices for thermostating the surfacing sites, a group of electrodes (19) placed in the surfacing head (17) for surfacing the nipple part of the pipe (10) fed from a single source of electric current ( 15), and a group of electrodes (19) for welding the coupling part of the pipe (9), placed in another surfacing head and fed from the second source of electric current, each surfacing head is installed with the possibility of linear and angular deviation from the "zenith" and its longitudinal horizontal and vertical movement and is connected with the feed mechanism (18) of electrodes (19) to the surfacing head (17) and a flux hopper (23), the supports for placing the pipe (1) are conductive with a “plus” connection to the pipe (1), and the “minus” to the electrodes (19), in each surfacing head the electrodes (19) are installed in row parallel arr binder tube (1) with the possibility of changing the distance between them, and longitudinal movement of an electrode assembly (19) is adapted to simultaneous supply of flux (24) in the welding zone.
