Description
Technical field
The invention belongs to the cold rolling manufacture field of ring, be specifically related to feed speed and workpiece size control method in a kind of cold ring rolling process.
Background technology
In the cold ring rolling process, feed speed and workpiece size are main process control parameters.Whether feed speed is stable, reasonable, determining the form accuracy and the working (machining) efficiency of workpiece, and workpiece size control influences dimensional accuracy.The feed speed of cold-rolling ring rolls control at present is to realize by the rotating speed of control drive motors, is not the speed of directly controlling the slide block feeding, can not make automatic correction and compensation to disturbing factor, and control accuracy is poor, and the workpiece machining accuracy is not high.Aspect workpiece size control, cold-rolling ring rolls adopts travel switch or software to send signal at present, controls slide block then and stops by even being decelerated to of predetermined ramp signal; This size Control mode is subjected to the interference of factors such as retro-speed and variations in temperature, and control accuracy is not high.
Summary of the invention
At above-mentioned deficiency, the object of the present invention is to provide feed speed and workpiece size control method in the strong cold ring rolling process of a kind of control accuracy height, antijamming capability.
The present invention adopts following technical scheme for achieving the above object: feed speed and workpiece size control method in a kind of cold ring rolling process is characterized in that comprising the steps:
1) directly detect the slide position of cold-rolling ring rolls by first sensor, the position signalling one tunnel that first sensor detects feeds back to positioner, and one the tunnel feeds back to speed control after derivator is handled;
2) detect workpiece size by second sensor, detection signal feeds back to positioner;
3) feedback signal of positioner receiving position command signal and first sensor, second sensor, the output of positioner is as the speed command signal of speed control;
4) feedback speed signal of speed control inbound pacing command signal and first sensor, the output signal control driving mechanism action of speed control, the drive mechanism slide block movement, thus workpiece size is changed;
5) output signal of positioner is being rolled over feedback signal and the position command signal decision of expansion starting stage by first sensor, the signal deciding of instructing by the feedback signal and the size of second sensor in the whole rolling stage, after rolling over the expansion beginning, constantly detect the slide position, and judge whether end of travel, if to end of travel then change workpiece size over to and detect control, meet the demands up to workpiece size.
The present invention detects and controls slide block feed speed and workpiece size, can make various disturbing factors and revising and compensation, has guaranteed the stability of feed speed, can improve the form accuracy of workpiece, the machining accuracy height.

The specific embodiment
Feed speed and workpiece size control method in a kind of cold ring rolling process, its principle comprises the steps: as shown in Figure 1
1) pass through the slide position that first sensor 1 directly detects cold-rolling ring rolls, the position signalling one tunnel that first sensor 1 detects feeds back to positioner, and one the tunnel feeds back to speed control after derivator is handled;
2) detect workpiece size by second sensor 2, detection signal feeds back to positioner;
3) feedback signal of positioner receiving position command signal and first sensor 1, second sensor 2, the output of positioner is as the speed command signal of speed control;
4) feedback speed signal of speed control inbound pacing command signal and first sensor 1, the output signal control drives structure action of speed control, the drive mechanism slide block movement, thus workpiece size is changed;
5) output signal of positioner is being rolled over feedback signal and the position command signal decision of expansion starting stage by first sensor 1, in the signal deciding that the whole rolling stage is instructed by the feedback signal and the size of second sensor 2, promptly the position controller has realized being controlled to by the slide position conversion of workpiece size control in the whole rolling stage;
The transfer principle that positioner was realized controlling to workpiece size control by the slide position in the whole rolling stage as shown in Figure 2, after rolling over the expansion beginning, constantly detect the slide position, and judge whether end of travel, if to end of travel then change workpiece size over to and detect control, meet the demands up to workpiece size.
As shown in Figure 3: form by man-machine interface, positioner, derivator, speed control, driving mechanism, slide block, first sensor 1 (being grating I), second sensor 2 (being grating II).Driving mechanism is made up of servomotor and transmission mechanism.Grating I is installed on slide block and the frame, and one of its feedback signal is connected to positioner, receives derivator for one, links speed control again; Grating II is installed on the workpiece size measuring mechanism, and its feedback signal is connected to positioner.Present embodiment in use, control instruction outputs to positioner by man-machine interface, compares with feedback signal, through overregulating, output to speed control, compare with the feedback signal of derivator output, through overregulating, output signal control servomotor rotates, and drive transmission mechanism, thereby the driving slide block movement, grating I moves on the slide block, produces feedback signal.Slide block promotes the motion of core roller, makes the ring wall thickness reduction, the ring enlarged-diameter, and the workpiece size measuring mechanism drives grating II and moves, and produces the workpiece size feedback signal.Positioner is being rolled over feedback signal and the position command signal decision of expansion starting stage by grating 1, in the feedback signal of whole rolling stage grating 2 and the signal deciding of size instruction, promptly the position controller has realized being controlled to by the slide position conversion of workpiece size control in the whole rolling stage.After workpiece was worked into and sets size, slide block was return, and finishes a working cycles.
Positioner of the present invention, speed control, derivator, first sensor 1, second sensor 2 can adopt known technology.
