A device for removing burrs in high-precision pipelines with built-in impedance

Abstract

The invention discloses a high-accuracy pipeline inside burr removing device internally provided with an impedance device. The high-accuracy pipeline inside burr removing device comprises a double-roll burr removing device (3) and the impedance device (2). One end of the impedance device (2) is inserted into the double-roll burr removing device (3) and the opposite end of the impedance device (2) is connected with production equipment through a fixing frame (1) in an angle adjusting manner. By the adoption of the high-accuracy pipeline inside burr removing device, the defects that a traditional cutter rod is adopted as a burr removing device, the fit degree of a blade and burrs of a weld joint is reduced, looseness occurs, and the application range of the cutter rod is narrow due to the influences of factors such as the size and the section shape of a pipeline are overcome, and the problems that a traditional magnetic rod serves as an impedance device, the magnetic rod is bent, and magnetic lines are not concentrated are effectively solved.

Description

technical field [0001] The invention relates to the technical field of high-frequency welding equipment, in particular to a device for removing burrs in a high-precision pipeline with a built-in impedance. Background technique [0002] High-frequency welding originated in the 1950s. It is a new welding process that uses the skin effect and adjacent effect generated by high-frequency current to connect steel plates and other metal materials. The emergence and maturity of high-frequency welding technology has directly promoted the huge development of the longitudinal welded pipe industry. It is a key process in the production of longitudinally welded pipes (ERW). The quality of high-frequency welding directly affects the overall strength of welded pipe products. Quality level and production speed. With the continuous development of the automobile industry and the construction industry, high-frequency welding technology will be used in the processing of small heat-dissipating ...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a device for removing burrs in high-frequency welded pipes with a built-in impedance. The present invention not only effectively solves the problem of using a traditional knife bar as a deburring device, but the fit between the knife edge and the weld burr will become loose, and the knife bar will be affected by the size of the pipe. , cross-sectional shape and other factors, the scope of application is narrow, and it effectively solves the problem that the traditional magnetic rod is used as the impedance, the magnetic rod will be bent, and the magnetic force lines are not concentrated.
