Abstract

The invention discloses a hydraulic pipeline pipe end forming connector, which comprises a connector body, a pipeline body, a sealing ring and a nut; the connector body comprises a connecting part provided with external threads, the connecting part is provided with a stepped hole with a small front part and a large rear part, and the rear end of the stepped hole is a conical hole; an annular anti-falling protrusion is formed at the pipe end of the pipeline body through a cold forming process; the sealing ring matched with the conical hole is arranged on the pipeline body in front of the annular anti-falling protrusion; and a nut in threaded connection with the connecting part is arranged on the pipeline body behind the annular anti-falling protrusion in a sleeved mode. Compared with the prior art, the requirements for the precision and hardness of a pipe can be lowered, the installation torque is reduced, and parts are reduced.

Description

【Technical field】 [0001] The invention relates to the technical field of pipeline connection, in particular to the technical field of a hydraulic pipeline pipe end forming connector. 【Background technique】 [0002] At present, the widely used metal pipe connection methods include threaded, welded, flared, ferrule and other pipe joints, and different connection forms and joints are used according to different working conditions and conditions. However, in today's industrialization and intensification, due to the advantages of ferrule-type pipe joints, such as good connection and sealing, and convenient and quick installation and operation, its application range and number of uses are constantly increasing, and higher requirements are also put forward. For example, the original double ferrule type pipe joint has high requirements for pipe precision and hardness in order to ensure its connection strength and tightness, and the required installation torque is relatively large, a...
