Abstract
Использование: металлурги , нефт на промышленность, область термомеханической обработки металлов. Сущность изобретени : протектор в виде тонкостенной конической оболочки штампуют взрывным штампованием и одновременно выдавливают резьбу, нагревают до температуры закалки и одновременно деформируют при напр жении 30-45 кг/мм2. Протектор дл ниппел обжимают в радиальном направлении , дл муфты раздают в радиальном направлении .Usage: metallurgists, oil for industry, the field of thermomechanical processing of metals. SUMMARY OF THE INVENTION: A protector in the form of a thin-walled conical shell is pressed by explosive stamping and simultaneously extrudes the thread, is heated to the hardening temperature and at the same time is deformed at a voltage of 30-45 kg / mm2. The tread for the nipples is crimped in the radial direction, for the sleeve is distributed in the radial direction.
Description
Изобретение относитс к термомеханической обработке металлов и может найти применение в металлургии и нефт ной промышленности .The invention relates to thermomechanical processing of metals and may find application in metallurgy and the petroleum industry.
Цель изобретени - обеспечение соединени протектора с замком, повышение надежности закреплени протектора на замке путем использовани обратной ползучести. The purpose of the invention is to provide a connection between the tread and the lock, increasing the reliability of securing the tread to the lock by using reverse creep.
Предлагаемый способ изготовлени стального протектора упрощает и повышает надежность закреплени протектора на защищаемом элементе путем использовани обратной ползучести. Операци закреплени протектора, изготовленного по предлагаемому -способу заключаетс в навинчивании протектора на защищаемый элемент, зат жке и нагреве до температуры, не вызывающей структурных изменений о стали. Набор таких простейших, легко контролируемых операций обеспечивает стабильность соединени протектора с защищаемым элементом.The proposed method for manufacturing a steel tread simplifies and increases the reliability of securing the tread on the element to be protected by using reverse creep. The operation of securing the tread made according to the proposed method consists in screwing the tread onto the element to be protected, tightening and heating to a temperature that does not cause structural changes about the steel. A set of such simple, easily controlled operations ensures the stability of the connection of the tread with the protected element.
Пример. Изготавливали взрывным штампованием под замковую резьбу 3-147Example. Made by explosive stamping under lock thread 3-147
замка ЗШ-178 ГОСТ 631-75 протектор в виде тонкой (толщиной 0,1 мм) конической обо- лочки с выдавленной резьбой, типоразмер которой одинаков с типоразмером защищаемой резьбы, т.е. 3-147, из стали ЗХВ4СФ, Проводили деформирование радиальным обжатием протектора в услови х совмещенного нагрева на ползучесть и закалку при напр жении 30 кг/мм2 с последующими разгрузкой и охлаждением в масле. Полученный стальной закаленный протектор навинчивали на ниппель замка ЗШ-178, зат гивали и нагревали до 450°С. Получали неразъемное соединение.lock ZSh-178 GOST 631-75 protector in the form of a thin (0.1 mm thick) conical shell with an extruded thread, the size of which is the same as the size of the protected thread, i.e. 3-147, made of ZHV4SF steel. Deformation was carried out by radial compression of the tread under conditions of combined heating by creep and quenching at a voltage of 30 kg / mm2, followed by unloading and cooling in oil. The obtained steel hardened tread was screwed onto the nipple of the lock ЗШ-178, tightened and heated to 450 ° С. Received one-piece connection.
