In metal processing, the straight wire drawing machine is a common type. In the past, a DC generator motor unit was usually used to complete it. Now, with the advancement of process skills and the widespread use of frequency converters, frequency conversion control has begun to be widely used in straight wire drawing machines. It can be controlled through PLC to complete functions such as drawing type setting, operation automation, production process control, real-time closed-loop control, and automatic meter counting. Below are the performance advantages of the straight wire drawing machine shared with you:
1. Choose a variable frequency speed regulation system with reliable skills and significant energy savings. The speed regulation range is 30:1 during normal operation, and it can provide over 1.5 times the additional torque at an additional speed of 5%. The straight wire drawing machine is mainly used to stretch the stainless steel wire produced by precision rolling. It is one of the more difficult to control types of wire drawing machines because it involves multiple motors working together to stretch the metal wire, resulting in high operational efficiency.
2. The metal wire slips between various molds, which requires high synchronization and fast dynamic response of the motor. Due to the brittle nature of stainless steel materials, they lack the durability of high carbon steel wire or steel cord, making them more prone to breakage during operation.
3. There are six 400mm diameter drums in the wire drawing section, and each drum is equipped with a cylinder swing arm for detecting the orientation. Displacement sensors can be used to detect the orientation of the swing arm. When the wire is pulled tightly, pressure will be generated on the cylinder of the swing arm, causing it to move downwards.
4. The winding motor adopts a self sliding conical bracket, and the winding diameter remains basically unchanged throughout the process, so there is no need to use the winding diameter calculation function. Select a frequency conversion dedicated motor with a mechanical braking device; The system logic control of the straight wire drawing machine is relatively complex, with various linkage connections, which are completed by PLC. The synchronization control is entirely completed within the TL-MD320 frequency converter, without relying on external control.
5. The control of the motor is harmonious and can reduce directional errors, enabling precise positioning of the tuning roller in the straight wire drawing machine.
6. The cut-off signal can be utilized to complete the step-by-step transmission of the transmission system. In this way, on the wire drawing machine, arbitrary cutting on the pass and corresponding maintenance work can be completed.
7. Automatic wire laying and tension adjustment organization can easily complete the automatic wire laying of metal wires, which can make the wire movement speed smooth, lubricate the surface of the wire, and prevent cracking and other problems, thereby improving the quality of the product.
