Online automatic rounding device for steel skeleton plastic composite pipe

Abstract

The invention discloses an online automatic rounding device for a steel skeleton plastic composite pipe. The online automatic rounding device for the steel skeleton plastic composite pipe is divided into two parts: a detecting mechanism and a calibration mechanism. The detecting mechanism and the calibration mechanism are sequentially fixed at the exit of a tractor. The detecting mechanism is composed of a first frame and eight laser range finders, and the calibration mechanism is composed of a second frame and eight pressure rolls. When working, the ellipticity of the pipe at the exit of thetractor in the continuous production process is detected firstly. When the ellipticity of the pipe exceeds the standard value, a signal is fed back to the calibration mechanism, and then the calibration mechanism corrects the ellipticity of the pipe. By means of the online automatic rounding device for the steel skeleton plastic composite pipe, the elliptic problem of the steel skeleton plastic composite pipe during the production process is solved, and the online automatic rounding is achieved. The online automatic rounding device for the steel skeleton plastic composite pipe is suitable forthe technical field of steel skeleton plastic composite pipe production.

Description

technical field [0001] The invention relates to an on-line automatic rounding device for steel skeleton plastic composite pipes. Specifically, the automatic rounding device is divided into two parts: a detection mechanism and a rounding mechanism. The ellipticity of the pipe is automatically detected online, and the result is fed back to the rounding mechanism. The invention solves the ellipse problem generated in the production process of steel skeleton plastic composite pipes and realizes online automatic calibration, belonging to the technical field of steel skeleton plastic composite pipe production. Background technique [0002] The steel skeleton plastic composite pipe adopts the welded steel mesh skeleton as the reinforcement layer, and the inside and outside are made of high-density polyethylene plastic, which is an ideal pipe for transporting water and corrosive fluids. In the production process, due to the deviation of the reinforced steel mesh skeleton or the poor...

Problems solved by technology

There are two problems in the above-mentioned technology: 1, measurement hysteresis

When the ovality of the pipe exceeds the standard value, it cannot be found in time; 2. The efficiency of the ovality correction tool is low and the labor intensity is high

The currently widely used steel inner support needs to be manually operated in the whole process. In order to ensure that the inner support has sufficient rigidity, the inner support is heavy, and the practicability and popularization are poor.
