Features of In-line Drawing Machine Using Variable Frequency Speed ​​Regulating System

May 29, 2018

In the process of using in-line drawing machine, the configuration will be able to reduce the production cost to some extent with the corresponding frequency control. We know that metal products are an important part of the metallurgical industry. In metal processing, straight-feed wire drawing machines are a common processing equipment. With the progress of process technology and the rapid popularity of frequency converters, frequency control has begun to be applied and applied.


At the same time, in actual operation, we can also achieve the setting of the drawing process through the PLC, automatic operation of the in-line drawing machine, production process control, real-time closed-loop control, automatic metering and other functions. After using the variable frequency speed control system, the entire process is more advanced and energy-saving, and the speed range is 30:1 during normal operation. At the same time, over 1.5 times of rated torque can be provided at 5% of rated speed.


In fact, the operation and control of the in-line wire drawing machine are complicated because the device is a multi-motor that stretches the wire at the same time, and its production efficiency is high. . Not only that, it has high requirements for the synchronization of the motor and the rapidity of the dynamic response.


In other words, taking into account the system logic control of in-line wire drawing machine is more complex, there are many kinds of linkage relations, and is achieved by the PLC. As a result, the control of its synchronization is entirely implemented inside the frequency converter and does not depend on external controls. Its working principle is to determine the speed of the job in the panel settings according to the operation. Under normal circumstances, the analog signal of this speed enters PLC, after considering the time of acceleration and deceleration through PLC, it will output analog signal according to certain slope.


Therefore, for the operation of the in-line wire drawing machine, we also optimized the parameter values of the system and set a stable running speed. In general, after using the variable frequency control system, the working efficiency of the equipment is obviously improved, and at the same time, the production cost has also been reduced.http://www.chinawiredrawingmachine.com/
