Since its inception, FGI has adhered to the path of professional development. The production of wire drawing machine special frequency converter has been widely used in the metallurgical industry since the end of the last century, of which the typical supporting manufacturers are Hebei Xianxian State-owned wire drawing machinery factory, Shandong Hongda building materials equipment Factory, etc., which replaced the imported brand frequency converter earlier. In recent years, with the high quality and rapid development of domestic wire drawing machinery, FGI has launched a new generation of high-performance vector FD300 series low voltage frequency inverter, a new design concept, a new control platform, a new manufacturing process, a wide power range, full coverage of functions, high reliability, strong scalability, simple operation, motor drive control more freely. While ensuring stable operation, it greatly reduces the production and use costs of enterprises.

1.introduction

Wire drawing machine is the key equipment in the field of wire processing, which is widely used in steel wire, plastic, cable, wood and other industries, common direct wire drawing machine, water tank wire drawing machine. Among them, the water tank wire drawing machine is generally used for metal wire processing, which is to process metal wire with different wire diameters into products with set wire diameters through wire drawing. The main drawing motor of the traditional wire drawing machine is started by series resistance, and the torque control is adopted on the side of the drawing motor. The three-in-one drawing machine launched by FGI has better improved the manufacturing process, production efficiency and equipment reliability of the drawing mechanism.

2.operating principle

The wire drawing machine needs to keep the tension constant in the process of wire drawing and pay-off, and the line of defense and take-up keep synchronized, there will be no broken line. The frequency of the main drawing motor can be used as the feedforward setting frequency to the take-up motor. As the disk diameter of take-up gradually increases, the frequency of take-up machine needs to be reduced, and the tension between take-up and defensive line is constant. That is, the frequency of the take-up motor is inversely proportional to the winding diameter.

3.Application process requirement

The low frequency output torque is large, the operation is not jitter, and the response speed is fast;
Prevent the occurrence of broken line, if the broken line fault must be stopped quickly;
Smooth operation process, avoid the pendulum rod touching the limit;
Maintain synchronization and continuous line during downtime.

4.FGI FD300 series low voltage frequency inverter features

Integrated main pull, take-up, line drive one, high integration;
Set touch screen, PLC, inverter integration, to provide system solutions, and easy to operate;
Low frequency torque lifting technology to ensure that the point threading is convenient and fast;
Optimized feedforward control algorithm to ensure smooth operation without broken lines;
PID control precision is high to ensure the smooth operation of the pendulum.
It has the function of self-adjusting the flatness of the line.

5.Use efficiency

Through excellent vector control and tension control technology, to achieve more sensitive speed control, to ensure the stability of the product;
Wire drawing machine frequency conversion special machine with automatic line break diagnosis and protection function, effectively protect the equipment, and improve the service life of the equipment;
High degree of product integration, to provide customers with system solutions, production efficiency is greatly improved.
