The wire drawing machine can be divided into a straight-through type and a water tank type by means of stretching. The wire diameter can be divided into a large drawing machine, a middle drawing machine, a fine drawing machine and a micro-drawing machine, etc. They are composed of two parts: the wire drawing and the wire. In order to improve the output, quality and cost of the cable, the wire drawing machine is generally changed to double-conversion or multi-conversion constant-tension control. At present, most of the variable-frequency synchronous control generally adopts the control mode of the external PID controller. The disadvantages of this method are as follows: The PID controller's control parameters are difficult to debug, expensive, and easy to damage. The analog quantity has attenuation and drift problems during transmission. The maintenance and maintenance costs are high. The use of the wire drawing machine inverter is easy to operate, easy to debug, and economical. It is a trend in the use of wire drawing machines. At present, the wire drawing machine of VEICHI is sold well all over the country, and its reputation is very good. It has won unanimous praise from various manufacturers in the field of wire drawing machines.
