Application of FGI FD300 series frequency inverter in plate rolling machine

1.Overview

The plate rolling machine is a kind of equipment that uses the working roller to bend the plate material, which can shape the cylinder parts, conical parts and other parts of different shapes, which is a very important processing equipment. The working principle of the rolling machine is to make the working roll move through the external force, so that the plate is bent or bent. According to the rotation motion and position change of different shapes of working rollers, elliptical parts, arc parts, cylindrical parts and other parts can be processed.

Due to the plate rolling machine used in different fields, the types are also different. From the number of rollers is divided into three roll rolling machine and four roll rolling machine. Three roll and divided into symmetrical three roll plate roll machine, horizontal three rod plate roll machine, arc line down plate roll machine, universal three roll plate roll machine, hydraulic CNC plate roll machine, etc.

2.Implementation plans

The control system of the rolling machine is composed of man-machine interface + PLC + FGI FD300 series frequency inverter. The transmission part is the lower roller, the lower roller translation, the hydraulic oil pump, and the roller station is controlled by one FD300 series frequency inverter (equipped with brake unit and brake resistance), combined with the external mechanical lock to achieve fast and accurate start and stop. Users can set the product parameters on the touch screen according to the process requirements and control the equipment with the console or wireless shake controller.

3.Application advantage

The transmission part of the equipment is all controlled by FGI FD300-type high-performance frequency converter, which ensures the synchronous and stable operation of the system, makes the system operation convenient, reduces the maintenance cost, and extends the service life of the machinery.

FD300 series frequency inverter has advanced vector control algorithm, drives the motor low speed large torque output, makes the whole system start and stop process smooth and accurate, realizes the rapid response of the system, and improves the working efficiency of the equipment.

It can provide complete protection functions such as overcurrent, overvoltage, undervoltage and overload, and realize the all-round protection of the motor, and make the system run stable and reliable.
