A device for removing the oxide layer on the surface of PE heterogeneous pipes

Abstract

The invention relates to a device for removing the oxide layer on the surface of PE heterogeneous pipes, which includes an electric planer mechanism, and the device for removing the oxide layer on the surface of PE heterogeneous pipes also includes a pipe fixing mechanism, a telescopic electric planer fixing component, and a device for controlling the operation of the electric planer mechanism. Limit-guiding limit tooling; the pipe fixing mechanism includes a central screw and a telescopic internal expansion fixing mechanism sleeved on the center screw; one end of the telescopic electric planer fixing component is fixedly connected to the electric planer mechanism, and the other end is installed There is a sliding assembly; the limit tooling for limiting and guiding the operation of the electric planer includes an outer sleeve driven by a central screw thread, and a ring guide rail is fixed inside the outer sleeve, and the telescopic electric planer fixing assembly The sliding assembly is connected with the ring guide rail. The invention can realize the scraping of the oxide layer on the surface of the heterogeneous PE pipe, and is convenient to operate, can precisely control the scraping thickness, and the scraping thickness is uniform, 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 an oxide layer on the surface of PE heterogeneous pipes. Background technique [0002] Due to the advantages of light weight, non-toxicity, wear resistance and corrosion resistance, PE pipes have been widely used in water supply, gas, oil fields, telecommunications and other fields. Generally, there are clear requirements in the construction manual of electric fusion pipe fittings. When welding PE electric fusion pipe fittings, the surface of the pipe to be welded must 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 to use a rotary scraper. The disadvantage is that the adaptability is not strong. For example, the rotary scraper model ERS200 can only process pipes with a diameter range of 75mm to 200mm. When the pipe diameter exceeds this range, other types of...

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
