Description

TECHNICAL FIELD

[0001] The utility model relates to a support for detecting the shape and bundle type of hot-rolled coil, belonging to the technical field of hot-rolled coil detection equipment. BACKGROUND

[0002] In the production process of hot-rolled coil, the outer diameter, center position and length of the hot-rolled coil need to be measured, and these shape measurements are crucial. For hot-rolled coils of different sizes, bundle type anomaly detection is also required to screen out hot-rolled coils with abnormal bundle type, thereby ensuring the normal operation of automated production. Therefore, bundle type anomaly detection of hot-rolled coil shape parameter measurement machines is an indispensable part of the production process, providing data support for the automation of production lines and meeting the growing demand of enterprises for hot-rolled coils.

[0003] Currently, in the production process of hot-rolled coil, steel enterprises collect production information after the wire is bundled into a coil by the hot-rolled coil bundling machine. The hot-rolled coil after bundling is sent to a designated position by a C-shaped hook, and then a worker measures the diameter of the coil with a tape measure on the end face of the coil and measures the length of the coil on the outer surface of the coil. Since the end face of the coil is not a regular plane, the measurement error is very large.

[0004] In addition, after the hot-rolled coil is bundled by the bundling machine, it may appear as an abnormal coil, which requires a worker to detect the inner and outer surfaces with a ruler. Although manual detection can detect and handle a part of the problem, more often than not, the problem is not discovered until the packaging process at the bagging station is completed. The abnormal shape of the coil not only seriously affects the production efficiency of the enterprise, but also limits the automation of the subsequent hot-rolled coil bundling line connection and hot-rolled coil bagging task. SUMMARY

[0005] The technical problem to be solved by the utility model is to provide a detection support for the shape and bundle type of hot-rolled coil.
