Talking about the advantages and disadvantages of the quality of wire nozzles

Talking about the advantages and disadvantages of the quality of alloy wire nozzles：

Tungsten wire nozzle is an important accessory that is widely used in winding machines. To select high-quality alloy wire nozzles from many suppliers with mixed advantages and disadvantages, it is inseparable from the key points: (1) wire nozzle outlet and the surface finish of the wire inlet (2) the finish of the inner hole (3) the dimensional accuracy of the inner diameter (4) the accuracy of the installation size (5) the R shape of the wire nozzle outlet and wire inlet.

What is the role of the five standards proposed above?

1. The smoothness of the nozzle orifice: its position at the junction of the inner hole and the arc angle cannot be seen clearly by visual means. There are obvious junction marks at the junction of the angle, so the result of it is to scratch the enameled wire. If it is a good quality wire nozzle, the junction between the inner hole and the arc angle is a natural transition, and there is no junction mark.

2. Inner hole finish: It is also very critical to the quality of the product. During the winding process of the product, the enameled wire is in a beating state in the inner hole of the wire nozzle. If the inner hole is not well ground, then scraping the wire is inevitable. It is worth reminding that there are many inner holes of Tungsten wire nozzles on the market that have not undergone precision grinding or simple rough processing, so users need to polish their eyes.

3. The dimensional accuracy of the inner hole: the precision machining of the nozzle, its inner hole accuracy can be controlled within 0.01mm, if the inner hole size is large or small, it is a disaster for the user, and you are busy enough , the phenomenon of disconnection will often occur, and even the wound coil has poor insulation or short circuit between turns. It is not difficult to explain the reason.

4. Accuracy of installation size: It is necessary to conform to the size of the installation. If it is large, it will be difficult to fit into the equipment fixture. If it is small, it will easily fall out of the fixture and affect the adjustment accuracy.

5. The R shape of the head and tail: The R shape of the head and tail is also a key part of the thread nozzle. Too large or too small R will affect the quality of the product and the tension it can withstand. The five points mentioned above are more critical. No matter how beautiful the surface finish is, it has nothing to do with the quality of the wound product. It is only beautiful, and the inner good is worth noting
