Wherein, described first motor and second motor are direct current generator, and described inlet roller 3 and outlet roller 4 are realized speed closed loop control by direct current generator.Described first speed regulator 10 and second speed regulator 11 adopt the total digital DC speed regulators, with guarantee transfer of data accurately, reliable, for speed control high accuracy and stability are given security.
Wherein, described inlet roller 3 and outlet roller 4 are the S forming roll.
Wherein, described band steel entrance and exit velocity measuring device 12 comprises inlet tachometer disc 5 and the outlet tachometer disc 6 that rotates with inlet roller 3 places and outlet roller 4 place's band steel motions respectively, with first encoder 7 of described inlet tachometer disc 5 coaxial settings, be used for to the inlet tachometer disc 5 count; With second encoder 8 of described outlet tachometer disc 6 coaxial settings, be used for described outlet tachometer disc 6 is counted, described first encoder 7 calculates control device 13 with second encoder 8 and described percentage elongation and is connected.Described first encoder 7 and second encoder 8 are counted by the certain hour cycle respectively, thereby can draw the actual percentage elongation of band steel.When operation conditions change, current detection changed by first encoder 7 and second encoder, 8 countings in the cycle, and the actual percentage elongation of the band steel that draws also changes.Described percentage elongation calculates control device 13 according to the actual percentage elongation δ that calculates 1With δ 2Deviation, output control signal Δ V, on the speed of first speed regulator 10 and second speed regulator 11 of being superimposed to respectively is given, thereby the actual speed of control inlet roller 3 and outlet roller 4 makes the actual percentage elongation of described band steel reach default percentage elongation and requires in the error range.
Because percentage elongation is very little amount, therefore described first encoder 7 and second encoder 8 adopt the incremental encoder of high-resolution (5000 pulses/more than commentariess on classics), and respectively with described inlet tachometer disc 5 with export tachometer disc 6 coaxial installations.Described inlet tachometer disc 5 can be pressed on the band steel that passes inlet roller 3 with hydraulic oil cylinder driving; Outlet tachometer disc 6 usefulness hydraulic oil cylinder driving are pressed on the band steel that passes outlet roller 4.
Wherein, described inlet tachometer disc 5 and outlet tachometer disc 6 equal preferred thickness are 30mm~100mm, and diameter is 200mm~500mm, wear-resistant vulcanie dish.Like this because the quality of tachometer disc is very little, inertia in the dynamic process of acceleration and deceleration can be very little, therefore can largely avoid after directly encoder being installed on inlet roller 3 and the outlet roller 4, causing the problem of encoder pulse-losing because of enter the mouth roller 3 and outlet roller 4 skid.
Wherein, described percentage elongation calculates control device 13 by adopting Programmable Logic Controller (PLC), man-machine interface adopts touch-screen to carry out operating parameters and sets and show, unreels 1, inlet roller 3, stretch bending-straightening machine 9, outlet roller 4, rolling 2 adopt main control cabinets to coordinate centralized Control and operations.On master operating station, percentage elongation, speed, tension force, the isoparametric setting of coil diameter can be carried out, also parameter situations such as percentage elongation, speed, tension force can be shown in real time by touch-screen.The control accuracy height of system, fast, the good stability of reaction.Operating personnel can start at master operating station, acceleration, deceleration or shut-down operation and by touch-screen on content displayed know the duty of complete machine, operation is very convenient.
