A self-sealing quick joint on the end face

Abstract

The invention discloses an end face self-sealing quick connector. The end face self-sealing quick connector comprises a valve body, an upper valve element, a sealing ring A, a sealing ring B, a sealing ring C, a bolt, a spring, a lower valve element and a sealing ring D. The upper valve element and the lower valve element are fixed into a whole through the bolt to form a valve element and mounted in the valve body. The spring is mounted between the valve element and the valve body. A certain precompression stress is applied to the spring in the mounting process. Reacting force can be applied to the valve element when the valve element is pressed on the other side of a pipeline so that the end face sealing ring A can conduct sealing. When the pipeline is disconnected automatically, the spring stretches to drive the valve element to move upwards and press the sealing ring D onto the conical surface of the valve body, and the effect of automatic sealing of an air channel is achieved when the pipeline is disconnected. By adopting the end face self-sealing quick connector, manual operation is not needed in the working process, and therefore the situation that an accident is caused by human factors is avoided. The connector has universality and can also be applied to other automatic air channels which need to be connected and disconnected automatically.

Description

technical field

[0001] The invention relates to a quick end face self-sealing joint used for automatic connection and disconnection of pipelines of stamping automation equipment, belonging to the technical field of stamping automation production. Background technique

[0002] With the development of my country's automobile industry, it is imperative to realize the trend of automatic production of large automobile panels. Among them, the fully automatic mold change technology of automatic stamping line is one of the basic requirements for automatic stamping production. During automatic mold change, the automatic gas circuit must be able to be automatically connected and disconnected when the mobile workbench is raised and lowered, and the gas circuit must be automatically sealed without leakage after the gas circuit of the pipeline is disconnected. The automatic gas path for the mold on the existing manual production line generally adopts a ferrule-type quick connector, and ...
