Metal pipe external thread protection treatment device

Abstract

The invention relates to the technical field of metal pipe chipless treatment, and provides a metal pipe external thread protection treatment device. The metal pipe external thread protection treatment device comprises a pipe opening treatment mechanism and conveying mechanisms; and the conveying mechanisms comprises lifting push plates which are arranged on the two sides of metal pipes located onthe pipe opening treatment mechanism correspondingly, and the lifting push plates on the two sides are in butt joint with feeding rails and discharging rails correspondingly. In this way, according to the metal pipe external thread protection treatment device, first rotating rollers and second rotating rollers which rotate in the same direction and at the same speed are used for supporting and driving the metal pipes to stably rotate, and rolling brushes coaxial with the first rotating rollers are used for treating threaded areas at pipe openings of the metal pipes, so that effective protection treatment on the pipe opening threads is achieved; the conveying mechanisms place the untreated metal pipes on the pipe opening treatment mechanism and taking down the treated metal pipes at the same time through the lifting push plates acting synchronously, so that feeding and discharging are rapid, the pipe opening treatment mechanism is short in idle time, and the equipment utilization rateis high; and the metal pipe external thread protection treatment device is simple and convenient to operate, low in labor intensity, capable of replacing manual treatment of the metal pipe openings and high in automation degree.

Description

technical field [0001] The invention belongs to the technical field of chip-free processing of metal pipes, and in particular relates to a protective processing device for external threads of metal pipes. Background technique [0002] Due to the need for anti-corrosion, the surface of the conduit body is usually galvanized. After galvanizing, threads are processed at the nozzle position for future connection. [0003] Because the threaded connection has certain precision requirements, it cannot be processed before galvanizing, but can only be processed after the overall galvanizing of the pipe. In this way, the coating in the threaded area of ​​the pipe orifice will be destroyed, and if no protective treatment is done, the service life of this area will be greatly reduced. [0004] At present, the protective treatment of this area only needs to be painted. Restricted by thread precision, the paint film requirements are also strict. The paint film must be evenly covered w...

AI Technical Summary

Problems solved by technology

Therefore, the existing painting equipment is difficult to adapt, and only manual painting can be used for protective treatment

The production efficiency is low, and the technical level of the operator is high, which is not conducive to mass production

[0005] In summary, there are obviously inconveniences and defects in the actual use of the existing technology, so it is necessary to improve
