Description
The utility model relates to a kind of control device of metal drawing, especially the take-up of water tank cooling type metal drawing and winding displacement control device.
Existing water tank drawbench electric-control system (typical in the TB4 type) still adopts the Direct Current Governor System of traditional relay control mode that take-up is controlled.This device belongs to five sixties products, and control mode is original, the fault rate height, and maintenance capacity is big, complicated operation.When the dynamic change of main frame speed, take-up operation is not permanent power mode, and take-up can not change by the dynamic following main frame, overtension or too smallly all can cause fracture of wire.When the main frame constant-speed operation, take-up is in permanent power mode.Along with the increase of take-up reel radius, take-up speed can be adjusted automatically, but can't adapt to sudden surge and interference, gently then causes fracture of wire, and is heavy then damage governing system.And Cable Assembly system adopt can not speed governing the mode of leading screw back and forth, the winding displacement inequality, wired serious.
The purpose of this utility model is: a kind of water tank drawbench control device is provided, and is a kind of control device that utilizes permanent tension force to adjust the metal drawing of take-up speed automatically; The purpose of this utility model also is to provide a kind of winding displacement control device that can speed governing, thereby guarantees the speed of a motor vehicle balance of machine, and tension force is all permanent, and winding displacement is neat, thereby the drawing speed of machine is improved, the quality of production is reliable and stable.
The purpose of this utility model is achieved in that a kind of control device of metal drawing, it is characterized in that main motor and take-up motor all adopt variable-frequency motor, take-up place is provided with tension pick-up, other is provided with the programmable PLC controller and connects main motor frequency conversion device, and the take-up variable-frequency governor is connected with the tension pick-up closed loop.
Further improvement of the utility model is: bus cable device is ball-screw and the variable-frequency motor that drives leading screw, and this frequency converter also is connected with the control end of Programmable Logic Controller.
The course of work of the present utility model is: by PLC sequential control main frame frequency converter, take-up frequency converter, start and stop, winding displacement commutation and the metering of winding displacement frequency converter, meter speed, and dynamically shown by the TD200 LCD.By detecting sensor, the PID closed-loop adjustment function (tension feedback employing current signal) that utilization take-up frequency converter itself has can realize permanent tension force speed governing automatically.Metering, meter speed in time, accurately, winding displacement is smooth, and is adjustable.The utility model can typically be used for the control device of TB4 type water tank drawbench.
Characteristics of the present utility model are: the variation that permanent tension closed loop frequency conversion speed-adjusting system can not only dynamic response main frame speed also has anti-interference and impact capacity.Along with take-up speed is adjusted in the increase of take-up reel radius automatically.Because the take-up frequency converter itself has PID closed-loop adjustment function, tension feedback adopts current signal, and antijamming capability is strengthened greatly.
Cable Assembly system changes the ac variable frequency speed regulation mode into by the hard waste mode of looking for of coming that can not speed governing.Strengthen adapting to the ability of technological requirement, improved reliability.
Logic control changes the PLC program controlled mode into by traditional relay mode.Structure is terse, and easily debugging, easily rectification easily are installed.
The main frame mode of speed regulation changes ac variable frequency speed regulation into by DC speed regulation, easily debugging, easy care.
High performance frequency control progressively replaces traditional DC speed regulation, to overcome direct current generator brush, the difficult difficulty of safeguarding of commutator damage.Reduced of the interference of the higher hamonic wave of reason controllable silicon DC speed regulation simultaneously, promptly reduced electric network pollution electrical network.
Adopt the motor of frequency control to move the situation that sound approaches to move on common frequency power network, reached quietization purpose.
Be mainly used in the drawing of thin specification wire as metal drawing such as TB4 water tank drawbench, require all very high for the control of tension force, winding displacement.Adopt the PLC control frequency control way of tension closed loop as TB4 water tank drawbench control system.Utilization PLC programme-control completion logic control and demonstration computational process are equipped with the frequency control completion logic control of closed-loop control again and show computational process, and the whole production control procedure is finished in the frequency control that can also be equipped with closed-loop control.Adopt the TB4 water tank drawbench speed of a motor vehicle balance of the utility model control device, tension force is all permanent, and winding displacement is neat.Thereby drawing speed improves, and the mould consumption reduces, and is difficult for wiredly, has improved the steel wire torsional strength.Steel wire output and lumber recovery all are improved.
The utility model is described in further detail below in conjunction with accompanying drawing and by embodiment:
Fig. 1 is the utility model block diagram;
Fig. 2 is the utility model circuit diagram:
Fig. 3 installs connection diagram for tension pick-up.
As shown in the figure: a kind of control device of metal drawing, in Fig. 1 block diagram, by the Controlled by Programmable Controller primary transducer, the take-up frequency converter, the winding displacement frequency converter, install in the connection diagram at Fig. 3 tension pick-up, this also is conventional tension pick-up, comprise cam 1, displacement transducer 2 is formed, cam 1 is connected with receipts thread tension arm, when tension force is big, cam offset is big, and be converted into current signal by displacement transducer 2, therefore tension feedback has adopted current signal, and tension feedback current signal input take-up frequency converter, take-up frequency converter itself have PID (ratio is regulated control) closed-loop adjustment function, the output of take-up frequency converter connects the input of PLC, PLC provides primary transducer according to this parameter, the speed control signals of winding displacement frequency converter etc., therefore, the utility model is the programmable PLC controller of tension feedback closed loop.Control to bus cable device is as follows: the variable-frequency motor of ball-screw and driving leading screw, this frequency converter also is connected with the control end of Programmable Logic Controller.
In Fig. 2 circuit diagram, Programmable Logic Controller adopts SR-10 (20) R-EX type, has provided SR-10 (20) among the figure
The wiring diagram of R-EX port, AC frequency conversion speed regulator typical case's model such as VFD-M type.The port of take-up AC frequency conversion speed regulator 4 is connected with 21 pin of SR-10 (20) R-EX, and provide rate signal and compare with the speed setting value of SR-10 (20) R-EX memory again simultaneously, thus the speed controlling value of decision variable-frequency governor.
SR-10 (20) R-EX adopts the expansion mouth to control variable-frequency governor, adopt variable- frequency governor 5,6 to come main control system motor, winding displacement motor respectively, promptly pass through the motion of Motor Control leading screw, the control of forward or reverse is by providing actuating signal near switch 7,8, thereby leading screw is pressed the different directions action.
