INVT frequency changer’s on drawing machine application

The majority used drawing machine’s domestic Jin Shujia the labor enterprise, was not strange to the frequency conversion velometer, this before was because the frequency conversion velometer very early, had in the wiredrawing machinery obtains the widespread application, but mostly disposed is the overseas brand frequency changer, the reason was the domestic frequency copper and aluminum wire drawing machine conversion velocity modulation technology research and development and the market introduction start is late, after for a period of time fell, in the overseas frequency changer product, not discussed from the software control algorithm sophistication, said from hardware platform’s stability, had certain bad distance.
The domestically produced frequency conversion profession underwent several year development, the technology and the market introduction obtained the considerable progress, developed the product which sent also to be able to be competent the major part industry scene to want. In view of the wiredrawing machinery’s application characteristic, Shenzhen UK prestige leaps the electrical Limited company to open from the host sends the development the INVT series frequency changer, the target of much criticism quantity control technology (VC, SVC), the torque control technology, the V/F control technology in a body, with, supposed counts has been advantageous for the same step control function and the tensity control function which the recover of wire used, true solved drawing machine’s control to comprehensively want, thus broke the aspect which the import brand monopolized.
Drawing machine, also famous draw machine. From the product terminal, the drawing machine may divide into Dollar machine, pulls machine, slightly pulls machine, micro pulls machine; Tied the construction from the drawing machine internal control way and the machinery, might also divide into the water box-type, the pulley type, the straight forward system and so on main several kinds. To in the various requirement, the different essence regular product, the different gold is the material, may choose the different specification the wiredrawing machinery. Lives to the electric wire electric cable produces the enterprise, the divariant frequency wire drawing machine control system pulls machine the application to be quite widespread thin, relatively speaking, its request’s control performance is also low, but lives to the majority of steel wires produces the enterprise, in view of the materials behavior, its essence requests and the drawing stability is high, therefore the use straight forward system drawing machine are many. The completely tube wiredrawing craft is different, but its work process base this with
* puts the line: The tinsel silk puts the line, to in the entire drawing machine link, its control has not had the high essence request, the majority of wiredrawing machinery, puts the line the operation is passes the frequency changer to actuate to put the coil to realize, but also has the minute divariant frequency control system wiredrawing machinery, automatic drawing machineeven passes the wiredrawing link’s silk thread tensity drafts to feed in the drawing machine directly, realizes from by puts the line;
* wiredrawing: The wiredrawing link is the drawing machine wants most for the work link which again. The different gold is the material, the different fibroin variety and the request, the wiredrawing link has the very big difference, article behind the specify water box-type drawing machine and the straight forward system drawing machine concrete operations process;
* recover of wire: The recover of wire link’s working speed had decided the entire wiredrawing machinery lives produces the efficiency, is also a minute which the overall system is most difficult to control. In the recover of wire department minute, the commonly used control technology has with a step die wire drawing machine control and the tensity controls the solid cash is the product receives the volume;
