Abstract

The invention discloses a servo fly-shear control method based on a novel control platform. The method comprises a hardware part and a software part, firstly, a novel-generation high-performance PLC is configured to be responsible for the logic control of the whole set of devices, the PLC servo control process is used for the servo control, and a servo controller in an old system is replaced; secondly, the Profinet network is adopted between the hardware equipment, all the servo electrical encoders and main transmission motor encoders also adopt the Profinet network, the TCP / IP protocol is implemented, the data transmission rate is increased, and the inherent scanning cycle is shortened; and finally, a novel detecting measure is established to optimize the software, the calculation date can be more accurate, and the shear accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of metallurgical automation, in particular to a servo flying shear control method based on a novel control platform. Background technique [0002] Servo flying shear is an important equipment in the high-speed wire rod production line. It is installed in front of the finishing mill. Its function is to cut the head, tail or accidental breaking of the rolled piece to ensure smooth rolling, reduce steel blocking and improve product quality. At present, high-speed wire products have a wide range of specifications and fast rolling speeds, up to 120m / s, requiring servo flying shears to reach a shear speed of 25m / s. Such processes require the use of continuous flying shears. [0003] The continuous flying shear is composed of three main electrical equipments: the front servo turning device, the flying shear body and the breaking shear. In the past, the transmission and automation system of continuous flying shear...
