Description

technical field [0001] The invention relates to a plate rolling measuring device for a plate rolling machine, in particular to a curvature measuring device for a plate rolling machine. Background technique [0002] Plate rolling machine is a general-purpose forming equipment that rolls metal sheets into cylinders, cones, curved surfaces or other shapes. It is widely used in boilers, shipbuilding, pressure vessels, chemical and machinery manufacturing and other industries. During the coiling process of the steel plate, the radius of curvature of the steel plate needs to be measured frequently to determine the next operation. The traditional method is to use a thin steel plate to make a curvature model according to the product requirements, and then compare it with the model during the production process, and judge the curvature trend based on experience by visually observing the degree of fit. Each product with different curvature needs to make a corresponding model, which i...

AI Technical Summary

Problems solved by technology

Each product with different curvature needs to make a corresponding model, which is labor-intensive, time-consuming and labor-intensive, and increases labor intensity

Most of the existing related technologies use the fixed chord length and the measured arc height, and then manually calculate the radius of curvature, which is inconvenient to use
