Measuring method of section profile and shape in cold-formed steel figuration process

Abstract

The utility model provides a measurement method for cross-section contour shape of cold-rolled forming section during forming process in measurement technical field. The utility model is characterized in that the length of a flexible strip with a hole-shaped structure is determined at first, then a keyway and potash soap are arranged on the flexible strip; fast gelatination material is prepared, mixed and filled; the flexible strip is tightly adhered and fixed; he condensed flexible strip is then removed and the cross-section shape is recorded. A transparent plastic sheet with the cross-section shape is spread on a piece of coordinate paper and the location is adjusted well so that the coordinate value of any point of the successive contour line can be read. The utility model can overcome the disadvantages in prior art that on-line measurement is not supported and the workpiece needs to be removed. The utility model is suitable for the shape measurement of on-line cross-section contour of various specifications of roll forming product as a fast, simple, flexible, safe, economic and practical method for measuring cross-section.

Description

technical field [0001] The invention relates to a method in the technical field of measurement, in particular to a method for measuring the profile shape of a section in the forming process of cold-formed steel. Background technique [0002] Cold-formed steel products mainly include welded pipes and special-shaped pipes. Because cold-formed steel has the advantages of light weight, metal saving, energy saving, and high geometric precision, its application fields are very wide, and it can be used as pipelines for gas, coal slurry, ore powder, etc., high and low pressure boiler tubes, and chemical heat exchanger tubes. , Oil well casing, pipe structural steel beams, structural steel grids, etc. With the rapid development of my country's economic construction, cold-formed steel will play an extremely important role in industry, agriculture, national defense and daily life. The shape and size of the cross-sectional contours of welded pipes and special-shaped pipes in the cold-...

AI Technical Summary

Problems solved by technology

[0005] The present invention aims at the above-mentioned deficiencies existing in the prior art, and provides a method for measuring the profile shape of the cross-section during the forming process of cold-formed steel, which overcomes the shortcomings of various previous methods for measuring the profile shape of the cross-section that are too complicated and cumbersome, and do not support online measurement. It is suitable for online continuous measurement of cross-sectional shape of cold-formed steel products of various specifications. It is a fast, simple, flexible, safe, economical and practical cross-sectional shape measurement method
