How to make the wound coil smooth and beautiful

This is a problem that has been puzzling coil processing enterprises.

The winding machine can't wind a flat, beautiful, strong and beautiful coil. Why? Is there a big gap between our winding equipment and imported equipment? In fact, China's winding equipment industry has experienced independent technology research and development, and its performance and accuracy can completely rival imported high-end, so where is the problem? The author thinks that most of the problems focus on the fact that users have not fully mastered the setting skills of winding equipment and made some reasonable adjustments according to the actual processing characteristics of their own products. The following is a simple analysis of our common problems:

Let's talk about special threads, such as self-adhesive threads and enamelled cotton threads. Processing these wires is very different from our common enameled wires. The processing equipment should be equipped with special wire passing wheel and tensioning mechanism, and the wire diameter should be appropriately increased when setting parameters. Because these wires are not smooth and have special coating, the wire diameter is generally larger than the nominal value.

Second, the common thin line processing, we generally call the line below 0.3 as thin line. When processing thin wires, it is generally easy to break wires, mostly in the process of starting and stopping. Therefore, the slow start and slow stop functions of winding equipment must be used to avoid wire breakage.

Third, thick thread processing is what we are most familiar with. It should be noted that the winding speed should be strictly controlled. If the speed is too fast, the coils will be irregularly arranged and the tension will fluctuate greatly. At present, the copper price has been high, and many manufacturers have turned to aluminum wires. It should also be noted that the tension requirements of the two wires are completely different. Under the same wire diameter, the tension of aluminum wire is only one third of that of copper wire, which is one of the main reasons for the explosion of external insulating paint for many users. With the continuous improvement of winding machine performance, can we talk about it again? It is also an ever-changing winding operation factor, which directly affects the smoothness and aesthetics of the coil and cannot be ignored.
