The application of machinery and equipment, mostly with the development of our industry is a certain relationship, the faster the development, then the application of these mechanical equipment will be the broader, of course, its existence or have certain benefits, drive the development of the industry, improve the processing efficiency of manufacturers, reduce the processing pressure of employees, in such a variety of advantages, machinery and equipment can be selected by so many manufacturers, there is also a certain The reason, for example, the application of external winding machine, you think the advantages are reflected in which places?

1, the coil size problem

Recently, when using a vertical winding machine to wind a single pancake type coil, the magnetic powder clutch to control the pull of the winding machine current value is set to 0.45A, the coil winding is completed B-end size are large, beyond the range of process requirements. As shown in Table 1.

2, the coil size problem cause analysis

When the vertical winding machine tension-related current value is set to 0.45A, the winding process found that the tension is too small, resulting in uneven force on the wire on the coil, when the coil rotates due to inertia coil idle phenomenon, the wire off more, resulting in the wire between the coil and the wire clamping device is not the ideal horizontal state, but sagging out of a certain arc, so the wire in the winding process is not uniform force Uniformity, and the winding of the completed line cake is not tight enough, thus leading to the coil B size is greater than the technical requirements.

3, winding machine tension and coil size relationship analysis

(1) the appropriate increase in winding machine tension on the impact of the coil. In the coil winding process, gradually increase the tension, the vertical winding machine tension-related current value is adjusted to 0.46A, the coil slack, as shown in Figure 2. The phenomenon of large size was improved, but still did not meet the requirements.

(2) The effect of excessive winding machine tension on the coil. Continue to increase the vertical winding machine tension-related current value to 0.51A, the coil in the winding process, the 4 corners of the force is too heavy, there is the phenomenon of upturn, after the completion of winding, the wire asked no obvious question gap, the wire gauge does not sharply reduce, but the 4 corners of the phenomenon of upturn, does not meet the technical requirements.
