PE heterogeneous pipe surface oxide layer removal device

Abstract

The invention relates to a PE heterogeneous pipe surface oxide layer removal device. The PE heterogeneous pipe surface oxide layer removal device comprises an electric planer mechanism, and further comprises a pipe fixing mechanism, a telescopic electric planer fixing assembly and a limiting tool. The limiting tool limits and guides the operation of the electric planer mechanism. The pipe fixing mechanism comprises a central threaded rod and a stretchable internal expansion fixing mechanism. The stretchable internal expansion fixing mechanism sleeves the central threaded rod. One end of the telescopic electric planer fixing assembly is fixedly connected with the electric planer mechanism, and a sliding assembly is installed at the other end of the telescopic electric planer fixing assembly. The limiting tool which limits and guides the operation of the electric planer mechanism comprises an outer sleeve. The outer sleeve is driven by the central threaded rod in a threaded mode, and anannular guide rail is fixedly arranged in the outer sleeve. The sliding assembly of the telescopic electric planer fixing assembly and the annular guide rail are cooperatively connected. By the adoption of the PE heterogeneous pipe surface oxide layer removal device, the scraping removal of a surface oxide layer of a heterogeneous PE pipe can be achieved, the operation is convenient and fast, thescraping removal thickness can be accurately controlled and is uniform, the device can adapt to different pipe diameters, and the cost is relatively low.

Description

Technical field [0001] The invention relates to the technical field of electric tools, in particular to a device for removing the surface oxide layer of a PE heterogeneous pipe. Background technique [0002] PE pipes have been widely used in water supply, gas, oil fields, telecommunications and other fields because of their light weight, non-toxic, wear-resistant, and corrosion-resistant advantages. Generally, there are clear requirements in the construction manual of electrofusion pipe fittings. When PE electrofusion pipe fittings are welded, the surface of the pipe to be welded needs to be deoxidized. [0003] At present, there are three main tools for removing the oxide layer on the surface of PE pipes on the market. One is the use of a rotating scraper. Its advantage is that the thickness of the oxide layer is uniform, which can make the pipe after the oxide layer have better out-of-roundness. The disadvantage is that the adaptability is not strong. For example, the rotary scr...

Problems solved by technology

However, this device cannot process PE pipes with small diameters, and is bulky, inconvenient to carry, and the cost of use, maintenance and maintenance is high

[0004] In addition to the above-mentioned defects, there is also a common defect in the commercially available or publicly available rotary scrapers and large-scale machining equipment, that is, they can only be processed for circular pipes, and they cannot handle heterogeneous pipes such as square pipes and oval pipes at all. deal with
