Abstract
The invention relates to the field of design of bar machining control, in particular to a bar apron board control process. The retention time of a braking sliding board in the neutral position ranges from 0 millisecond to 50 milliseconds. The process has the advantages that the retention time of the braking sliding board in the neutral position is shortened to be within the 50-millisecond period, steel directly goes to the high position from the lower position, a front piece of finished steel and a rear piece of finished steel can be thoroughly separated, the deviation of the tail position of the front piece of finished steel and the head portion of the rear piece of finished steel is increased, the phenomenon that the steel goes to improper cooling beds is avoided, and efficiency is improved.
Description
Technical field
The present invention designs bar machining control field, and more specifically a kind of bar skirtboard is controlled technique.
Background technology
In rolling bar process, the brake sliding plate of cooling-bed apron plate is divided into low level, meta, high-order three course of action, former course of action finally completes an actuation cycle process to an initial position high position to meta by an initial position high position again after low level, in this course of action, finished steel slides at a high speed after skirtboard, brake sliding plate action big-endian stops 850ms again in the middle of meeting after meta, and then returns to high-order initial position by meta.
The effect of meta a: bar enters after group plate certain distance above, brake sliding plate is down to low level by a high position, now bar is along with the decline landing of brake sliding plate is to bottom, then brake sliding plate can rise to meta and stay for some time at meta, there is this time of staying just to produce meta, now the present bar above of meta acting body is turned down skirtboard, then a bar enters after skirtboard and blocks it is stayed in skirtboard, two of front and back bar is separated, because to translate into low level by a high position be the process of a deceleration to this process of meta to a bar more above, then a steel is the process of an acceleration under the effect of roller-way, the afterbody that is unlikely to occur last steel after two bars are kept apart is by the head of a rear steel such phenomenon that knocks into the back.
Yet, since going into operation, there is such problem in this technology always, that is exactly that the tail end of skirtboard last bar when rising to meta usually can not come by turning down on skirtboard, turn in the situation of not getting off and often just easily by a rear bar, knocked into the back, thereby cause the accident, if reduce bar length or adjustment turn over the steel time will reduce lumber recovery or bar do not increase cold bed to not assigned address cannot carry out next process, along with skirtboard is used wearing and tearing and along with the lifting of bar rolling speed, problem is more serious for a long time.Cause random bed, reduced lumber recovery, reduced rolling time and operating rate, increased staff labor intensity.
Summary of the invention
Goal of the invention of the present invention is for above-mentioned deficiency, provide a kind of and can reduce the phenomenon knocking into the back before and after bar, the bar skirtboard of increasing work efficiency is controlled technique, this technique was reduced to the time of staying at meta in cycle of 50 milliseconds, steel directly to high-order, can, so that two of front and back finished steel thoroughly separates, increase the first position deviations of two of front and back steel tail by low level, avoid random bed, improved efficiency.
Summary of the invention
Skirtboard is controlled a technique, comprises the steps:
(1) after rolled bar, after nibbling shear, enter inlet roller way, braking return board drops to low level, and first bar slides;
(2) braking return board rises, and the head of second bar enters inclination roller-way Shang district, and holds it in this position by skimming baffle, until brake sliding plate goes back up to meta;
(3) brake sliding plate is at meta 0-50 millisecond; Baffle plate is opened, and second bar slides into the sidewall of keep plate, and first bar slides in cold bed by rising to high-order braking return board;
(4) braking return board drops to status, repeats said process.
The described brake sliding plate of above-mentioned steps (3) is at meta 0-30 millisecond.
The described brake sliding plate of above-mentioned steps (3) is 0 millisecond of meta.
The invention has the beneficial effects as follows: this technique was reduced to the time of staying at meta in cycle of 50 milliseconds, steel directly to high-order, can, so that two of front and back finished steel thoroughly separates, increase the first position deviations of two of front and back steel tail by low level, avoid random bed, improved efficiency.
