Description
Technical field
The invention belongs to technical field of industrial control, be specifically related to a kind of control method of High Precision Disc Shear Overlap.
Background technology
In band process line, such as in the middle of the units such as the strip processing line of metallurgy industry------continuous annealing unit or pickling unit, width due to finished strip requires the width being less than incoming band steel sometimes, usually needs to be fallen by Partial Shear unnecessary for incoming band steel both sides with circle shear before finished product volume is formed; There are two cutterheads (cutting edge) the every side of circle shear, be respectively upper tool pan and lower cutterhead, upper tool pan maintains static, lower cutterhead can be elevated, usual needs control adjustable height and lap (the i.e. distance of upper and lower cutterhead cutting edge overlap of lower cutterhead according to the thickness of band steel, when the cutting edge of upper and lower cutterhead is in same level position, lap is now 0.
The setting value of lap is determined according to band steel actual (real) thickness, shears the band steel of different-thickness, needs to reset lap, be generally 1.1 times of belt steel thickness; Lap can not set greatly, otherwise easily damages cutterhead, can not be too little, in general needs the precision controlling of lap within 0.005mm.
Chinese invention patent " the lap controller parameter optimization method of cut edge circle shear " (application number: the lap controller parameter optimization method that 201210470487.0) the invention discloses a kind of cut edge circle shear, the mode utilizing PID to regulate controls lap, and lap deviation can be made to reach certain limit.But the method control mode is complicated, and do not record the accuracy value that can realize in literary composition, those skilled in the art do not know the concrete precision that the method can realize.
Summary of the invention
For the deficiencies in the prior art, the invention provides a kind of control method of High Precision Disc Shear Overlap.The present invention includes inner ring to control and outer shroud control, outer shroud controls to be used for comparing to the lap position of lower cutterhead physical location and setting, determines the controlled quentity controlled variable that lower cutterhead moves; Inner ring controls the controlled quentity controlled variable controlled by receiving outer shroud, and drives servomotor to select by the mode of pulse, and the high accuracy realizing circle shear overlying quantity controls.Method of the present invention controls simply, is easy to realization, and control accuracy can reach 0.005mm.
Technical scheme of the present invention is: a kind of control method of High Precision Disc Shear Overlap, comprise inner ring control, outer shroud control, upper tool pan and lower cutterhead, wherein upper tool pan is fixed, lower cutterhead controls it by inner ring and moves up and down, it is characterized in that: described outer shroud controls to be determined by absolute value encoder the physical location of lower cutterhead, then comparing with needing the lap position set, determining that lower cutterhead needs the distance of movement, and this needed controlled quentity controlled variable to be transferred in inner ring control;

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further illustrated.
A kind of control method of High Precision Disc Shear Overlap, comprise inner ring control, outer shroud control, upper tool pan and lower cutterhead, wherein upper tool pan is fixed, lower cutterhead controls it by inner ring and moves up and down, outer shroud controls the physical location being determined lower cutterhead by absolute value encoder, then comparing with needing the lap position set, determining that lower cutterhead needs the distance of movement, and this needed controlled quentity controlled variable to be transferred in inner ring control.Inner ring controls the amount of moving as required, calculates the quantity exporting pulse, and by the lifting of cutterhead under servo controller driving servo motor driven, thus the high accuracy realizing High Precision Disc Shear Overlap controls.
As shown in Figure 1, circle shear of the present invention has upper tool pan, lower cutterhead two cutterheads, and wherein upper tool pan maintains static, and lower cutterhead can be elevated; The present invention is by regulating the height of lower cutterhead to regulate the lap of two cutterheads.
As shown in Figure 1, lower cutterhead of the present invention is controlled by servo motor, and servo motor is controlled by servo controller (driver), is controlled the position of lower cutterhead by number of pulses.And servo controller (driver) is controlled by siemens PLC controller, according to position deviation amount S7-200 controller output control pulse to servo controller (driver), number of pulses determines lifting position, thus complete the position control of lower cutterhead, this inner ring being lap controls controls, by the actual umber of pulse received of servo controller to determine the physical location of lower cutterhead, thus control lap.
In addition, lower cutterhead is also furnished with an absolute value encoder, for remembeing each positional value of lower cutterhead, the actual value of this encoder enters into the senior PLC of S7-400 as position feed back signal, this controller is the master controller that lap controls, the outer shroud controlled as lap controls, and accurately controls, thus accurately control lap according to setting lap with the actual physical location of position to lower cutterhead.
This control flow chart as shown in Figure 2.
Two accuracy guarantee links are had in this control system:
1, in order to improve control accuracy, be related to each pulse in system and export, lower cutterhead moves 0.001mm.Such as, in S7-200 controller, displacement corresponding to every 1000 pulses is 1mm, and under namely system often exports a pulse, cutterhead moves 0.001mm, has controlled umber of pulse well, not only can improve control accuracy, also facilitate System Programming.
2, in S7-400 controller, because system time is by reading the actual value of displacement encoder, and comparing with setting value, forming negative feedback closed loop and controlling, thus avoid the error that may bring due to pulse missing, improve control accuracy further.
The control system of dicyclo accuracy guarantee of the present invention, not only can improve the control accuracy of circle shear, and control method is simple, is easy to realize.Method of the present invention is easy to circle shear overlying quantity precision controlling in the scope of about 0.005mm.
