Cylinder rounding device of pressure vessel

Abstract

The invention discloses a cylinder rounding device of a pressure vessel. The cylinder rounding device of the pressure vessel includes a hollow disk support, eight supporting rods and a detection mechanism. The supporting rods include steel rods, jacks, roller supporting heads and supporting arms. One ends of the steel rods are evenly connected to the hollow disk support by screw threads. The two ends of the jacks are separately welded to the steel rods and the supporting arms, and the supporting arms are connected with the roller supporting heads. According to the cylinder rounding device of the pressure vessel, the problems of large measurement errors and multiple human factors occurring in a traditional cylinder side rounding process are solved, meanwhile, the degree of automation of detection is improved, and the adjustment efficiency is greatly improved.

Description

technical field [0001] The invention relates to the field of pressure vessel measurement, in particular to a pressure vessel cylinder circle calibration device. Background technique [0002] With the rapid development of the chemical industry, in the container manufacturing industry, the application of large-diameter cylinders is becoming more and more extensive. However, various defects may occur in the process of processing, forming, welding and assembling of the pressure vessel, which will affect the quality and performance of the vessel. Defects such as roundness, misalignment of welds, and deformation of seam corners produce edges and corners. The cross-section of the cylinder is not round, which means that there is a difference between the maximum diameter and the minimum diameter of the cylinder on the same cross-section, and during the production process of the cylinder, the blanking, rolling and other processes and the self-weight of the cylinder are easy to cause ...

AI Technical Summary

Problems solved by technology

The method used to improve the ellipticity of the cylinder in our country is basically to manually use clamps such as kalan or angle iron, or to make rough adjustments by the processing master himself and use steel pipe supports under appropriate circumstances. The method is backward and the accuracy is very poor, and The quality of the finished product varies with the ability of the processing master, the adjustment efficiency is very low and wastes manpower, and the measurement accuracy error is large. A pressure vessel cylinder circle calibration device is hereby developed.
