Abstract
Изобретение относитс к машиностроению и может быть использовано при сн тии остаточных напр жений в издели х в сварочном и механосборочном производствах. Цель изобретени - улучшение качества изделий за счет сн ти напр жени . Сущность изобретени заключаетс в одновременном ударном воздействии на изделие в каждом цикле колебаний в противоположном направлении этим колебани м путем ограничени перемещени упругой волны на 1/3-2/3 от максимального значени амплитуды колебаний. 1 табл.The invention relates to mechanical engineering and can be used to relieve residual stresses in products in the welding and mechanical assembly industries. The purpose of the invention is to improve the quality of products by relieving stress. The essence of the invention is to simultaneously impact the product in each cycle of oscillations in the opposite direction to these oscillations by limiting the displacement of the elastic wave by 1 / 3-2 / 3 of the maximum value of the oscillation amplitude. 1 tab.
Description
Изобретение относитс к машиностроению и может быть использовано при сн тии остаточньк напр жений в издели х в сварочном и механосборочном производствах.The invention relates to mechanical engineering and can be used to relieve residual stresses in products in the welding and mechanical assembly industries.
Цель изобретени - улучшение качества изделий за счет сн ти напр жений .The purpose of the invention is to improve the quality of products by relieving stress.
Способ осуществл ют следующим образом.The method is carried out as follows.
Пример. Выполн ли вибрационную обработку детали типа труба из сплава АМг-Зм длиной 600 мм, наручным диаметром 50 мм с толщиной стенки 1 мм с целью получени стабильности геометрических размеров (наружного диаметра) при сборке и эксплуатации. Без стабилизирующей обработки .овал наружного диаметра после вылеживани в течение 10 сут. составл ет 0,2-0,4 мм при допуске - 0,06 мм. Обработку вели на виброг остенде 2365-Р с частотой 65 Гц. Деталь размещали внутри другой трубыExample. Vibration processing of an AMg-Zm alloy tube with a length of 600 mm and a wrist diameter of 50 mm with a wall thickness of 1 mm was carried out in order to obtain stability of geometrical dimensions (outer diameter) during assembly and operation. Without a stabilizing treatment, the outer diameter after aging for 10 days. is 0.2-0.4 mm with a tolerance of 0.06 mm. The treatment was conducted on a vibrog ostend 2365-P with a frequency of 65 Hz. Item was placed inside another pipe.
(медной) так, что зазор между наружной поверхностью детали и внутренним диаметром медной трубы составл л 0,5 мм (максимальна амплитуда колебаний детали в свободном состо нии составл ет 1 мм). Результат испытаний оценивали по изменению диа- метра трубы в процессе вылеживани в течение 30 сут.(copper) so that the gap between the outer surface of the part and the inner diameter of the copper pipe was 0.5 mm (the maximum amplitude of oscillation of the part in the free state is 1 mm). The test result was evaluated by changing the pipe diameter during the curing process for 30 days.
Результаты испытаний приведены в таблице.The test results are shown in the table.
Из таблицы видно, что предлагаемый, способ обеспечивает более высокую стабильность геометрических размеров изделий во времени.The table shows that the proposed method provides a higher stability of the geometric dimensions of products over time.
Применение предлагаемого способа позвол ет сократить энергетические и капитальные затраты на вибрационную обработку за счет применени одного вибровозбудител , повысить качество обрабатываемых изделий и уменьшить опасность разрушени издели в процессе обработки.The application of the proposed method allows to reduce the energy and capital costs of vibration processing by using a single vibration exciter, improve the quality of processed products and reduce the risk of destruction of the product during processing.
