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

Embodiment Construction

[0016] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0017] As shown in Figure 1, it includes an organic base 7, and a spindle box 5 is installed on one side of the upper part of the base. To clamp the pipe to be processed, a rear chuck 4 can also be arranged at the rear end of the spindle box to facilitate the clamping of long pipes; on the other side of the upper part of the machine base, two axial guides are installed in front and behind parallel to the centerline of the spindle. Column 15, slide plate 14 is arranged on the guide post, and gear and hand wheel 16 are arranged on the slide plate, and the gear and the rack set on the front axial guide column are arranged to form a hand-operated mobile slide plate; on the slide plate A thread rolling roulette 10 coaxial with the main shaft is installed on one side of the relative spindle box. The thread rolling roulette includes a chassis 11 connected with ...

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...
