Device for detecting size of circular tube by using double X-ray emitters

Abstract

A device for detecting the size of a circular tube by using double X-ray emitters is provided, two groups of rollers arranged up and down are mounted on supports on two sides of a base, a shell is provided with an opening for the circular tube to enter and exit, the two X-ray emitters are mounted on the base and located between the supports on the two sides, and the two X-ray emitters are respectively located on two sides of the axial direction of entering and exiting of the circular tube; an imaging plate corresponding to the X-ray emitter is arranged above the X-ray emitter through a movable bracket. 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 loss of machine adjusting materials is reduced; the defective rate is reduced and the production efficiency is improved. By means of the double X-ray emitters, the irradiation range of the single X-ray emitter can be utilized to the maximum extent, imaging is clearer, and the size of the round tube capable of being detected is larger.

Description

technical field [0001] The invention relates to a detection method, in particular to a device for detecting the size of a circular tube using double X-ray emitters. 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 very easy to change, and the pulling of the tractor If the speed is too fast or too slow, the wall thickness will become thinner or thicker. To make matters worse, the materials and equipment used to produce round tubes are unstable every day, resulting in deviations in the outer di...

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
