pressure and negative pressure deflate. After a certain time, the safety curve just opens and the box opens. So far, the automatic work is completed. Superfine wire refers to the wire diameter of the incoming wire of 0.1-0.5mm and the outgoing wire diameter of 0.03-0.15mm.
The traditional ultra micro wire drawing machine is mostly single frequency conversion. The system adjusts the belt position on the two cone wheels by detecting the speed of the constant speed wheel and guide wheel to control the speed difference (changing to the speed ratio of the take-up wheel). However, with the development of the market, the customer's requirements are higher and higher, and the shortcomings of the single frequency conversion wire drawing machine are more and more obvious. First of all, the cone pulley belt increases the fault point, which is seriously worn and has a high damage rate; Secondly, the running speed cannot be improved due to the limitation of mechanical structure, which seriously affects the improvement of production efficiency;
