AI Technical Summary
The sealing structure of existing local vacuum welding devices is prone to suction and detachment during vacuum welding, as well as circumferential movement or radial rolling caused by uneven friction, resulting in the inability to maintain a stable vacuum level.
It adopts an inverted trapezoidal structure that combines an insert ring with an assembly ring groove, combined with a filling ring cavity and an anti-slip structure. It uses high-temperature resistant elastic materials and is equipped with an active cooling circulation system to form a wedge-shaped anti-detachment and redundant sealing barrier, ensuring the stability of the sealing structure.
It effectively reduces the probability of the sealing structure detaching and shifting during vacuum welding, ensuring the stability of the vacuum level and the welding quality, and improving welding efficiency and reliability.
