Изобретение относитс к машиностроению,а именно к технологии демонтажа резьбовых соединений , и может быть использовано при ремонте различного оборудовани .The invention relates to mechanical engineering, in particular to the technology of dismantling threaded connections, and can be used in the repair of various equipment.
Известен способ демонтажа резьбовых соединений , по которому в стержне резьбового конца 5 охватываемой детали соединени сверл т продольное отверстие, в отверстии формируют внутренние кольцевые ребра, канавки между ними заполн ют огнеупорным теплоизолирующим материалом, а затем внутренние поверхности ребер нагревают Ю с последующим принудительным охлаждениелт и приложением крут щего момента 1.There is a known method of disassembling the threaded connections, in which a longitudinal hole is drilled in the threaded end 5 of the male part of the joint, the internal annular ribs are formed in the hole, the grooves between them are filled with refractory heat-insulating material, and then the internal surfaces of the ribs are heated with 10, followed by forced cooling and application torque 1.
Известный способ имеет сложную технологию, так как в сравнительно небольших по диаметру 15 резьбовых детал х затруднительно выполнение операции набивки теплоизол ции в канавки между ребрами.The known method has a complicated technology, since in a relatively small diameter of 15 threaded parts, it is difficult to carry out the operation of stuffing thermal insulation in the grooves between the ribs.
Целью изобретени вл етс упрощение процесса демонтажа.The aim of the invention is to simplify the dismantling process.
Эта цель достигаетс тем, что на внутреннюю поверхность кольцевых ребер накладь1вают кольцевые сварные швы., .This goal is achieved in that annular weld seams are applied to the inner surface of the annular ribs.
Предложенный способ извлечени резьбовых деталей по сн етс чертежом, на котором показано резьбовое соединение в разрезе.The proposed method of removing the threaded parts is illustrated in the drawing, which shows the threaded joint in section.
Первоначально шпильку 1 резьбового соединени обрезают вблизи.корпуса 2. Затем вдоль оси шпильки 1 на всю глубину резьбовой части сверл т отверстие 3. С помощью расточного приспособлени (не показано) на. внутренней поверхности шпильки 1 формируют кольцевые ребра 4. Толщина стенки 5, получаемой расточкой, выбираетс не меньшей, чем высота профил резьбы во избежание сквозного прорезани стенки 5. Высота Т и ширина В ребер 4 определ ютс исход из размеров зоны проплавлени . Затем на внутреннюю поверхность каждого ребра 4 нахладьтают кольцевой сварной шов 6. При этом исключение перегрева стенки 5 во избежание осевой усадки стенки 5 вследствие ее пластической деформации достигаетс принудительным охлаждением ребра 4, следующим немедленно после наложени сварного шва. Initially, the stud 1 of the threaded joint is cut near the housing 2. Then, a hole 3 is drilled along the axis of the stud 1 to the full depth of the threaded portion. Using a boring device (not shown) on. The inner surface of the stud 1 forms annular ribs 4. The thickness of the wall 5 obtained by the bore is chosen to be no less than the height of the thread profile to avoid through-cutting of the wall 5. The height T and width B of the ribs 4 are determined based on the dimensions of the melting zone. Then, the annular weld 6 is cooled to the inner surface of each rib 4. The elimination of overheating of the wall 5, in order to avoid axial shrinkage of the wall 5 due to plastic deformation, is achieved by forced cooling of the rib 4, immediately following the application of the weld.
Изобретение позвол ет при извлечении дефекных или прикипевишх резьбовьш деталей увеличить усадку JBHHTB, тем самым расшир область применени способа. Кроме того, предлагаемый способ технологически проще, так как позвол ет отказатьс от теплоизол ции в канавках между ребрами.The invention allows for the extraction of defective or near threaded parts to increase the shrinkage of JBHHTB, thereby expanding the scope of application of the method. In addition, the proposed method is technologically simpler, since it allows refusing heat insulation in the grooves between the ribs.
