Description

.(54) УСТРОЙСТВО ДЛЯ СВАРКИ ТЕРМОПЛАСТИЧНОГО МАТЕРИАЛА
Изобретение относитс  к сварке n/tasi масс.
Известно устройство дл  сварки термопластичного материала экструдированным присадочным материалом, выполнен- 5 кое в виде мундштука с направл ющим каналом, снабженного элементом дл  направлени  по шву, расположенным впереди канала по ходу сварки н формирующим шов элементом, расположенным сзадиIQ
мундштука по ходу сварки.
Г юдложенное устройство отличаетс  тем, что направл ющий элемент вьшол- не  ® виде выступа, примыкающего к ка- наиу и соответству эщего по форме раз- is де ки под Q apkyi а формирующий емент ыполней в,йййё плоского-йлемёнта, придкшощёго к кайаЯу и имеющего внутренкао поверхность, соответствующую усиленшо щва.20
На фиг. 1 показано предлагаемое устойство , продольный разрез; на фиг. 2 - то же, поперечный разрез.
Устройство дл  сварки термопластичного материала содержит мундштук 1с.25
направл ющим каналом 2, служйщим дл  подачи экструдированного присадочногО материала и. обогреваемым с помощью элактронагревательной ткани 3, покрытой изол цией 4,
Мундштук снабжен направл ющим элементом 5, выполненным в виде выступа, примыкающего к каналу и соответствук щего по форме разделки под сварку, и формирующим элементом 6, выполненным в виде плоского элемента, примыкающего к каналу и имеющего внутреннюю поверхность 7, соответствующую усиле1шю швп и выполненную в соответствии-с требуемой формой щва.
. Формирующий элемент соединен винтс)вым соединешшм руко ткой ,9 мундщтука . Кроме того, на руко тке крепитс  сопло-10 дл  подачи нагретого газа.
Сварку термопластичного -материала с помощью предлагаемого устройства осуществл ют следующим образом.
Включае1х;  нагрев канала 2 дл  подачи экструдированного присадочного материала с помощью электронагревательной
ткани 3 и подача нагретого воздуха через сопло 10. Наплавленный материал, вход щий в формирующий элемент 6 через канал 2, продвигает направл ющий эле мент 5 с мундштуком вперед в направле НИИ сварки, сварные швы с помощью этого устройства получаютс  одинаково плотньь ми и с гладкой поверхностью.
