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, more specifically a kind of bar skirtboard Controlling Technology.
Background technology
In rolling bar process, the braking return board 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, after in this course of action, finished steel slides to skirtboard at a high speed, braking return board 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: after a bar enters group plate certain distance above, braking return board is down to low level by a high position, now bar is along with the decline landing of braking return board is to bottom, then braking return board can rise to meta and stay for some time at meta, this time of staying has been had just to create meta, now meta acting body will turn down skirtboard by a bar above now, blocking after then a bar enters skirtboard makes it stay in skirtboard, two, front and back bar is separated, because a bar translates into by a high position process that low level is a deceleration again to this process of meta above, then a steel is a process accelerated under the effect of roller-way, be unlikely to after two bars are kept apart to occur that the afterbody of last steel to be knocked into the back such phenomenon by the head of a rear steel.
But, there is such problem in this technology since operation always, that be exactly skirtboard last bar when rising to meta tail end usually can not by skirtboard is turned down come, often just easily knocked into the back by a rear bar when turning over to get off, thus cause the accident, if reduce bar length or adjustment to turn over the steel time and will reduce lumber recovery or the bar cold bed that do not increase and cannot carry out next process to not assigned address, along with the wearing and tearing of skirtboard Long-Time Service and the lifting along with bar rolling speed, problem is more serious.Cause random bed, reduce lumber recovery, decrease rolling time and operating rate, add staff labor intensity.
Summary of the invention
Goal of the invention of the present invention is for above-mentioned deficiency, there is provided a kind of and can reduce the phenomenon knocked into the back before and after bar, the bar skirtboard Controlling Technology of increasing work efficiency, this technique is by within the cycle that the time of staying of meta is reduced to 50 milliseconds, steel directly to high-order, can make two, front and back finished steel thoroughly separate by low level, add the steel tail first place offset of two, front and back from, avoid random bed, improve efficiency.
Summary of the invention
A kind of bar skirtboard Controlling Technology, comprises the steps:
(1) enter inlet roller way after nibbling shear after rolled bar, braking return board drops to low level, and first bar slides;
(2) braking return board rises, and the head of second bar enters the upper district of inclination roller-way, and holds it in this position by skimming baffle, until braking return board goes back up to meta;
(3) braking return board is at meta 0-50 millisecond; Baffle plate is opened, and second bar slides into the sidewall of braking return board, and first bar slides in cold bed by rising to high-order braking return board;
(4) braking return board drops to low level, repeats said process.
Above-mentioned steps (3) described braking return board is at meta 0-30 millisecond.
Above-mentioned steps (3) described braking return board is meta 0 millisecond.
The invention has the beneficial effects as follows: this technique is by within the cycle that the time of staying of meta is reduced to 50 milliseconds, steel directly to high-order, can make two, front and back finished steel thoroughly separate by low level, add the steel tail first place offset of two, front and back from, avoid random bed, improve efficiency.
