Rolled piece width measuring system and method for rolling mill manipulator

Abstract

The invention discloses a rolled piece width measuring system and method for a rolling mill manipulator. The system comprises laser range finders, laser alignment plates and a PLC data acquisition system, wherein the laser range finders are correspondingly arranged on the two sides of the manipulator, the laser alignment plates are arranged on push heads and are positioned in the longitudinal center positions of the push heads, and the PLC data acquisition system is used for collecting data and remotely transmitting the data. According to the rolled piece width measuring system and method, theinfluence of violent vibration of the manipulator on the precision of a measuring device can be effectively avoided, the stability of the rolling machine manipulator width measuring system is greatlyimproved, and the damage rate of equipment is reduced.

Description

technical field [0001] The present disclosure relates to the field of width measurement on a push bed of a wide (medium) thick plate rolling mill, and in particular to a width measurement system and a width measurement method for a rolled piece during the centering process of the rolled piece on the push bed. Background technique [0002] In the steel plate rolling process of wide (medium) thick plate rolling mill, the calculation of the width is generally carried out through the centering process of the rolled piece on the pusher bed. The real-time on-line measurement data of the width of the rolled piece by the pusher of the rolling mill directly affects the control of the quality and shape of the rolled steel plate. [0003] At present, the width measurement of rolling mill pusher mostly adopts the built-in displacement sensor of the push rod hydraulic cylinder of the pusher bed, or the method of adding a pulse encoder to the synchronous drive shaft. Due to the harsh envi...

AI Technical Summary

Problems solved by technology

[0003] At present, the width measurement of rolling mill pushers mostly adopts the built-in displacement sensor of the push rod hydraulic cylinder of the pusher, or the method of adding a pulse encoder to the synchronous drive shaft. Due to the harsh environment of the production site during the rolling process, the impact vibration of the equipment is large, and the built-in Displacement sensors or pulse encoders are prone to garbled code fluctuations, and are in mechanical hard contact with the body of the push bed, which is easy to be damaged, causing production accidents, affecting product quality control, and increasing equipment maintenance costs

[0004] To sum up, at present, there is still no effective solution to the problem of detection equipment damage or measurement deviation caused by equipment impact and vibration during the rolling process
