The figure above shows the small drawing machine’s control model, is the present mainstream complete copper and aluminum continuous control mode, the stretch and the volume takes controls controls machine IPC by PLC or the labor to complete, the frequency changer accepts PLC or the IPC instruction, realizes permanent tensity control which the stretch level’s stepless speed regulation and the volume take. This system solution will directly cause the cost soaring, the system complex, the maintenance difficulty big, the maintenance cost high, questions and so on systems control response difference.
The above schematic drawing is INVT the control mode which recommends to you, these two kinds medium, small, miniature extend the line machine electric control way, takes the volume function integrations and so on synchronization and tensity control, system start and parking control, malfunction alert in the frequency changer, melts with the mechanical system is a whole, the external signal sends in the frequency changer directly, after the internal algorithm rapid reaction to system’s positive governing, enhanced system’s speed of response greatly, omits PLC, HMI, IPC, saves the continuous extrusion machine system cost, reduces the fault point, and may dispose LED or the LCD control panel according to the user’s needs, manifests the man-machine operation user-friendly, convenient user’s operation, maintenance, debugging and use.

Taiwan reaches the BW series frequency changer’s on compound -like continual drawing machine application

The drawing machine is in the metal wire rod processing important equipment, uses in processing the metal original material Cheng Ge to plant the specification wire rod. The drawing machine by puts parts and so on line, wiredrawing, water cooling, recover of wire copper continuous extrusion machine and row of line is composed, in which electric drive part mainly by puts the line electrical machinery, the recover of wire electrical machinery and the row of line electrical machinery realizes, its production quality and the efficiency say very important regarding the enterprise. The drawing machine may divide into the pulley type, conciliatory -like, the orthoscopic three kinds. From the product terminal, the drawing machine may divide into Dollar machine, pulls machine, slightly pulls machine, micro pulls machine; But from the drawing machine internal control way and the structure, may divide into the water tank type, pulley type, straight forward system and so on main several kinds. Regarding the various requirement, the different precision different specification’s product, the different metal type, may choose the different specification the wiredrawing machinery. Regarding the copper aluminum parent metal’s electric wire electric cable Production enterprise, the divariant frequency control system pulls machine the application to be quite widespread thin, relatively speaking, its request’s control performance is also low, but regarding the majority of steel wire aluminum continuous extrusion machine Production enterprise, in view of the steel products characteristic, its accuracy requirement and the drawing stability is high, therefore the use straight forward system drawing machine are many, different wiredrawing machinery, its work process basic same:
Puts the line: the l tinsel puts the link speed, regarding the entire drawing machine link, its control not high accuracy request, to the part divariant frequency control system wiredrawing machinery, even may stretch using the wiredrawing link’s silk thread tensity through the disc. To the majority of wiredrawing machinery, puts the line the control is actuates the paying out machine through the frequency changer to realize.
Wiredrawing: the l wiredrawing copper and aluminum wire drawing machine link is the drawing machine most important link. The different metal material, the different product precision and the request, the wiredrawing link has the very big difference, the divariant frequency control system drawing machine wiredrawing part with puts a line partial common electrical machinery, the tinsel through internal cone pulley’s guiding, after mold, but stretches gradually. But the straight forward system drawing machine stretches the efficiency to be high, to each wiredrawing working procedure, needs an electrical machinery to lead, therefore its control is also most complex.
The compound -like continual drawing machine is one kind uses in drawing the metal wire rod straight forward system continual drawing machine, will compose or two continual drawing machine’s all wire drawing machine single drawing machines distributes abreast in row according to 2~4 rows and by the horizontal form simultaneously places, in has on the vertical plane rack, all mold box installment also will be located on the rack and causes it to have certain included angle with the horizontal plane, the product has occupies a land area few, is advantageous in the enhancement labor productivity and realizes the health and the civilizing production.
The compound -like continual drawing machine is parallel arranges 2-4 row straight forward system continual drawing machine, its transmission, the lubrication, cooling and the control and the erectness straight forward system drawing machine is the same. This aircraft altogether has 10 cone pulleys, 1 drawer roller, 1 receives the winding reel, 11 molds, as well as 11 swing links, biggest coil in diameter 2.4mm, smallest going beyond a line diameter 0.3mm, most altitude speed 2.5m/s. The cone pulley diameter is 250mm, tows the wheel diameter is 360mm, receives the winding reel most minor die wire drawing machine diameter is 280mm. Raw material wire rod stretches through 11 mold’s 11 levels, turns needs the line diameter the end product wire rod. Each cone pulley by 1 motor control, the drawer roller and receives the winding reel also separately by 1 motor control. Each cone pulley disposition swing link, takes when the permanent tensity control uses. Each electrical machinery through the speed reducer and the solderless joint, the reduction gear ratio following table 1 shows (reduction gear ratio G is load side gear/electrical machinery side gear) the compound -like drawing machine’s frequency conversion permanent tensity actuation goal is to guarantee in moves in the process the silk thread tensity to be constant. According to the mechanism and the material difference, the permanent tensity control’s method divides into two kinds generally: 1 positive governing electrical machinery output torque, 2 constant guarantees the tensity through the control speed constant. Through to mechanism’s hydraulic automatic drawing machine analysis, this project uses through the control speed method comes the indirect operation tensity constant.
