Flying shear control system and flying shear control method

Abstract

The invention discloses a flying shear control system and a flying shear control method. The flying shear control system is divided into a management layer, a control layer and an equipment layer, wherein the management layer comprises an upper computer; the control layer comprises a DCS (Distributed Control System) main station, an I / O (Input / Output) slave station and a frequency converter; the frequency converter, the I / O slave station and the upper computer are communicated with the DCS main station by DP (Data Processing) buses respectively; the equipment layer comprises a synchronous servo motor, a direct current motor, a pair of hydraulic flying shears and a first detection switch; the first detection switch is connected with the I / O slave station and mounted ahead the pair of hydraulic flying shears; a rotary encoder is arranged on a transmission shaft connected with the synchronous servo motor; an incremental encoder is arranged on a transmission shaft connected with the direct current motor; the synchronous servo motor and the rotary encoder are connected with the frequency converter, respectively; the direct current motor is connected with the DCS main station by a direct current driver; and the incremental encoder is connected with the frequency converter and the direct current driver respectively. The system and the method has the advantages of high shearing precision, strong working stability, high responsivity and the like.

Description

technical field [0001] The invention relates to the technical field of flying shear control, in particular to a flying shear control system and a control method thereof. Background technique [0002] Flying shear is an important equipment for the production of long products such as steel, bar and wire. It is widely used in the metallurgical industry, especially in the steel industry, machine tool industry and various rod and wire industries. It is a modern type of strip steel, bar and wire. It is an essential key equipment in production lines such as wire rods. However, many production lines still use the first-generation or second-generation flying shear systems. These systems generally have problems such as slow speed, low efficiency, low precision, high failure rate and difficult maintenance, which seriously affect the benefits of enterprises. Most flying shear systems urgently need to be updated, but currently there is no domestic manufacturer capable of producing flyin...

Problems solved by technology

However, many production lines are still using the first-generation or second-generation flying shear systems. These systems generally have problems such as slow speed, low efficiency, low precision, high failure rate and difficult maintenance, which seriously affect the benefits of enterprises.

Most of the flying shear systems are in urgent need of replacement, but currently there is no domestic manufacturer capable of producing flying shear systems with high precision and high efficiency
