Abstract

Изобретение позвол ет расширить номенклатуру свариваемых изделий различного диаметра путем изменени  радиуса кривизны уплотн ющей поверхности. Радиус кривизны уплотн ющей поверхности механизма герметизации зависит от угла а, который измен етс  с изменением диаметра свариваемого издели . В процессе сварки шкивы 23, охватываемые уплотни- тельными элементами 25, и четыре ролика 27 механизма герметизации опираютс  на поверхность свариваемого издели . При этом уплотнительные элементы 25 плотно прилегают к свариваемому стыку. Устройство обеспечивает повышение производительности труда при электронно-лучевой сварке крупногабаритных изделий различного диаметра. 10 ил.The invention allows to expand the range of welded products of different diameters by changing the radius of curvature of the sealing surface. The radius of curvature of the sealing surface of the sealing mechanism depends on the angle a, which varies with the diameter of the product to be welded. During the welding process, the pulleys 23 covered by the sealing elements 25 and the four rollers 27 of the sealing mechanism rest on the surface of the product to be welded. In this case, the sealing elements 25 are tightly attached to the weld joint. The device provides increased productivity in the electron-beam welding of large-sized products of different diameters. 10 il.

Формула изобретенияClaim Устройство для электронно-лучевой сварки крупногабаритных изделий в локальном вакууме, содержащее электронно-лучевую пушку, механизм герметизации с уплотнением для герметизации стыка, отличающееся тем, что. с целью расширения номенклатуры свариваемых изделий различного диаметра путем изменения радиуса кривизны уплотняющей поверхности, механизм герметизаций, выполнен в виде челнока с шарнирно закрепленными шкивами и эластичных подвижных уплотнений замкнутого контура для охвата шкивов и боковых поверхностей челнока, при этом электронно-лучевая пушка установлена на челноке.A device for electron beam welding of large-sized products in a local vacuum, containing an electron beam gun, a sealing mechanism with a seal to seal the joint, characterized in that. In order to expand the range of welded products of various diameters by changing the radius of curvature of the sealing surface, the sealing mechanism is made in the form of a shuttle with pivotally fixed pulleys and elastic movable closed-loop seals to cover the pulleys and side surfaces of the shuttle, while the electron beam gun is mounted on the shuttle.
