How to choose the guide needle for the wire nozzle of the winding machine

How to choose the guide needle for the wire nozzle of the winding machine:

The key to purchasing the guide needle of the nozzle of the winding machine is not how good the surface finish is, how beautiful the surface finish is, it has nothing to do with the quality of the wound product, it is just beautiful, and the inner good is worth noting. The following are 5 small points shared by Jincheng Industry Co., Ltd. for your reference.

First, the accuracy of installation dimensions:

The consistency of the installation size is necessary. If it is large, it is difficult to fit into the equipment fixture. If it is small, it is easy to fall out of the fixture and affect the adjustment accuracy.

Second, the dimensional accuracy of the inner hole:

The precision of the inner hole can be controlled within 0.01mm. If the inner hole is large or small, it will be a disaster for the user. It is enough for you to be busy, and the phenomenon of disconnection will often occur. It is not difficult to explain the reason, even if the wound coil has poor insulation or inter-turn short circuit.

Third, the R shape of the head and tail:

The R shape of the head and tail is also a key part of the nozzle. Too large or too small R will affect the quality of the product and the tensile force it can withstand.

Fourth, the 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. Now there are many alloy wire nozzles on the market that have not undergone precision grinding or simple rough processing, so users need to keep their eyes open.

Fifth, the finish of the line mouth orifice:

Its position at the junction of the inner hole and the arc angle cannot be seen clearly by visual means, only with the help of a high-magnification magnifying glass to observe from the side, if there are obvious intersection marks at the junction of the inner hole and the arc angle , then the result it brings is to scratch the enameled wire. If it is a high-quality wire nozzle, the junction between its inner hole and the arc angle is a natural excess, and there is no junction mark.
