Equipment and method for detecting size of circular tube by using X-ray imaging technology

Abstract

According to the method and the equipment for detecting the size of the circular tube by using the X-ray imaging technology, two groups of rollers which are arranged up and down are mounted on brackets on two sides of a machine base, an X-ray emitter is mounted on the machine base and is positioned between the brackets on the two sides, and an imaging plate corresponding to the X-ray emitter is mounted on the opposite side above the X-ray emitter through a movable support. Scientific calculation is carried out after X-ray image acquisition and sharpness processing. According to the invention, the penetration performance of the X-ray is utilized to detect the round tube without damaging the round tube, so that the machine adjusting efficiency is improved, and the material loss is reduced; the defective rate is reduced and the production efficiency is improved.

Description

technical field [0001] The invention relates to a detection method, in particular to a device and a method for detecting the size of a round pipe using X-ray imaging technology. Background technique [0002] The round pipe is generally extruded from a variety of materials after being heated and melted by the extruder, stretched continuously by the tractor, shaped by the cooling tank, and finally cut into a fixed length pipe by the cutting machine. The extruder has an outer mold and an inner mold, which are used to determine the center of the outer wall of the circular tube and the center of the inner wall. The circular tube extruded from the extruder, because the material is not cooled, the wall thickness is easy to change, and the pulling speed of the tractor Too fast or too slow will result in thinning or thickening of the wall thickness. To make matters worse, the materials and equipment used to produce round tubes are unstable every day, resulting in deviations in the o...

Problems solved by technology

However, sawing the round pipe will cause the deformation of the round pipe at the section, so the wall thickness data of the round pipe measured by this method is unreliable

At the same time, this method of measurement and adjustment takes a long time, relies on the experience and sense of responsibility of skilled workers, and causes serious waste of materials, which may easily lead to unqualified batches of finished products

[0006] Similarly, in the quality inspection management, the quality inspector needs to saw the sampling tube, and use a caliper to measure the wall thickness on the sawn end face, the measurement efficiency is low, the accuracy is not high, the sampling data ratio is small, and the data is unreliable
