Main features of PLC control mode for straight-in wire drawing machine

May 08, 2018

Straight-feed wire drawing machines are very common in modern industrial fields. In practical applications, the equipment can process different specifications of wire rods into thin wires with the required specifications. The electric transmission part of the in-line wire drawing machine is mainly realized by a pay-off motor, a pull-wire motor and a take-up motor.


At present, when designing and processing straight-feed wire drawing machines, special attention is paid to its control system. In many workplaces, PLC control systems are used. In this way, in the process of drawing, the setting of drawing speed, motor speed adjustment, system operation automation, production process control, real-time pld closed-loop control and fixed-length control can be realized through PLC and inverter.


In modern production work, users often choose different drawing equipments according to their actual needs. Among them, the in-line drawing machine's precision and drawing stability are outstanding, and it has become the main processing equipment of the metal cable manufacturing industry. The work flow of the equipment can be mainly divided into three processes: take-off, drawing and take-up. Among them, the requirements for the control accuracy of the pay-off link are general, and the drawing link is the most important one.


In fact, in the course of drawing work using a straight wire drawing machine, there are often differences in the drawing process for different metal materials, different types of silk products and requirements. At the same time, the control of the take-up link, ie the take-up speed, determines the production efficiency of the entire wire drawing machine. Commonly used control techniques include synchronous control and tension control to achieve the winding of metal products.


For example, in a straight-line drawing machine used by a certain production enterprise, PLC control mode is used in particular, and the PLC control system is the core part of the entire control system. The frequency conversion governor and asynchronous AC motor belong to the controlled object. In this way, the entire system can be simplified, the service life of the in-line wire drawing machine can be extended, and various actions and functions can be realized.http://www.chinawiredrawingmachine.com/
