Pipeline connection external thread oxial rolling machine

Abstract

An axial thread rolling machine for making external spiral thread on pipe is composed of machine frame, mainshaft box with chuck, slide carriage, longitudinal guide rod or track, and threading disk coaxial with mainshaft.

Description

technical field [0001] The invention relates to a processing equipment for thread rolling forming, in particular to a processing equipment for axial rolling forming of pipeline external threads for sealing connection. Background technique [0002] Due to its flexible use and convenient installation, pipe threaded joints are widely used in the connection of small and medium diameter pipes. Existing external threads at the ends of metal pipes are usually processed by cutting. Not only is the production more troublesome, but also the processed external thread has low precision and poor finish. Especially when the external thread is cut on the pipe wall, the flow line of the metal internal structure will be cut off, and the pipe wall will become thinner, resulting in a decrease in the connection strength of the pipe joint, and the phenomenon of pipe running, popping, dripping, and leaking often occurs during use. In order to overcome the above shortcomings, a rolling pipe exte...

AI Technical Summary

Problems solved by technology

Because the fiber streamline of the metal internal tissue is not cut and is continuous, a dense metal reinforcement layer is formed on the metal surface through extrusion strengthening, so that the strength, connection performance and serviceability of the external thread are effectively improved and improved. , compared with cutting and processing pipe joint threads, it improves the thread precision and surface strength, reduces the thread assembly margin, better solves the problems of running, popping, dripping and leaking at the pipe joints during use, and greatly improves the sealing connection performance , but currently there is no mechanical processing equipment that can quickly and efficiently process the external threads of the above-mentioned pipes
