Description
Technical field
The present invention relates to field of metallurgical equipment, is the control method of small tension receiving coil threading.
Background technology
On metallurgical rewinding production line, in crossing process, equipment surface and strip surface form friction, and causing strip surface wearing and tearing is common phenomena.At present, more conventional mode is that uncoiler is velocity mode, and all the other each transmission rollers adopt the feeding forward of little moment of torsion amplitude limit mode, to reach the object of the steady threading of band to coiling machine.But in practical operation, because band does not initially have tension force, cause band complications or shake in crossing process, thereby form the flaws such as cut in strip surface.Based on this, we have developed the uncoiler small tension receiving coil pattern control method of threading feeding forward.
Summary of the invention
The object of this invention is to provide a kind of control method of small tension receiving coil threading, for solving the flaws such as or surface scratch that fluctuation cause tortuous at crossing process band.
Technical scheme of the present invention is the control method of small tension receiving coil threading, its hardware comprises unit master controller, operating desk, uncoiler motor, transmission device and roller transmission device, it is characterized in that: each several part hardware is equipped with software, the speed of unit main controller controls set state and tension force are set, there is T400 board transmission device inside, T400 board calculates coil diameter, speed and tension force, actuator drives uncoiler motor, operating desk and unit master controller pass through Profibus-DP communication, and carry out threading control according to following step:
Step 1, control operation platform sends threading instruction, and unit master controller takes orders, and crossing process starts; Now the unit speed speed of starting is 0; Uncoiler is tension mode, and uncoiler motor speed is biasing speed-Vs, uncoiler motor reversal; Roller transmission device is velocity mode, and its speed is 0;
Step 2, after band is strained because of uncoiler reversion, small tension receiving coil is set up, and uncoiler motor stops operating because of tension force, and actual speed is 0;
Step 3, unit is sent out threading speed Vt, uncoiler motor continue send out a biasing speed-Vs, roller transmission device with Vt to coiling machine feeding, thereby pull uncoiler to rotate with actual speed Vt;
Step 4, after band is delivered to coiling machine to three circle and rolled tightly, unit is set up normal tension, and small tension receiving coil threading finishes, and unit enters running status.
Described unit master controller is Siemens 416-2DP PLC controller.
Described uncoiler motor is speed governing variable-frequency motor.
Described transmission device and roller transmission device are Siemens 6SE70MasterDriver inverters.
Feature of the present invention is control and the foundation that has comprised tension force, has effectively controlled speed and tension force, has solved the flaws such as in crossing process band is tortuous or fluctuation causes surface scratch.
Detailed description of the invention
Unit master controller is selected Siemens 416-2DP PLC controller, and PLC, for controlling the state of unit, has comprised the setting of speed and tension force etc.
Uncoiler motor is speed governing variable-frequency motor, and transmission device is Siemens 6SE70MasterDriver inverter, and device is inner with T400 board, for completing the control of coil diameter calculating and speed and tension force, and actuator drives uncoiler motor.
Roller transmission device Ye Shi Siemens 6SE70MasterDriver inverter.
Operating desk is by manual operation, and operating desk and unit master controller PLC are by Profibus-DP communication.
When work, when meeting threading condition, operating personnel press " threading " button at operating desk, and threading work starts, and carries out threading according to following step:
Step 1, control operation platform sends threading instruction, and unit master controller takes orders, and crossing process starts; Now the unit speed speed of starting is 0; Uncoiler is tension mode, and uncoiler motor speed is biasing speed-Vs, uncoiler motor reversal; Roller transmission device is velocity mode, and its speed is 0;
Step 2, after band is strained because of uncoiler reversion, small tension receiving coil is set up, and uncoiler motor stops operating because of tension force, and actual speed is 0;
Step 3, unit is sent out threading speed Vt, uncoiler motor continue send out a biasing speed-Vs, roller transmission device with Vt to coiling machine feeding, thereby pull uncoiler to rotate with actual speed Vt;
Step 4, after band is delivered to coiling machine to three circle and rolled tightly, unit is set up normal tension, and small tension receiving coil threading finishes, and unit enters running status.
Wherein, unit master controller, uncoiler motor, transmission device and roller transmission device and each several part software control belong to the common technology of this area, are not described in detail at this.
Carry out threading by above method, can effectively solve the flaws such as in crossing process band is tortuous or fluctuation causes surface scratch, and the method is easy to operate.
