Referring to fig. 2, fig. 2 is a schematic flow chart of a method for controlling pre-swing of a pushing bed according to an embodiment of the invention, which includes the following steps:
S10: and acquiring roller way parameter information, billet parameter information and pushing bed parameter information.
Specifically, in this embodiment, as shown in fig. 3, the roller way has a conical structure with a thick end and a thin end. The roller way parameter information comprises the length of the roller way, the diameter of the thick end of the roller way, the diameter of the thin end of the roller way and the linear speed of the thin end of the roller way. The length of the roller way, the diameter of the thick end of the roller way and the diameter of the thin end of the roller way are inherent properties of the roller way, and can be preset. The linear speed of the thin end of the roller way can be preset, and real-time acquisition can be performed through acquisition equipment.
The steel billet parameter information comprises steel billet length, steel billet width and steel turning angle. The length and width of the steel billet are inherent properties of the steel billet, and can be preset, and can be acquired and identified through CCD camera equipment. The turning angle is the angle through which the billet turns, and as shown in fig. 3, the turning angle is α.
The pushing bed parameter information comprises the actual opening size of the pushing bed, the maximum running speed of the pushing bed and the minimum running speed of the pushing bed. The actual opening size of the pushing bed can be preset, and acquisition and identification can be performed through equipment. The maximum running speed and the minimum running speed of the pushing bed can be preset, the speed control of the pushing bed in the pre-swing control can be regulated by a proportional valve, a typical centering control curve of the pushing bed is set as shown in fig. 4, the horizontal axis x is the deviation between the opening size of the pushing bed and the parallel size of the roller way axis when the steel is turned in place, and the pushing bed can be considered to be centered when the deviation is smaller than e 0.
The running speed of the pushing bed is calculated according to the formula (1):
Corresponding to fig. 4, when the deviation is greater than e 2, the speed set by the pushing bed is the maximum speed V max of the pushing bed operation; when the deviation is between e 1~e2, the speed of the pushing bed is the linear interpolation between the minimum speed of the pushing bed V 0 and the maximum speed of the pushing bed V max; the deviation is between e 0~e1, and the speed set by the pushing bed is the minimum speed V 0 of the pushing bed; the deviation is smaller than e 0, and the speed set by the pushing bed is 0.
In this embodiment, e 0 is 100mm; e 1 is 200mm; e 2 takes 300mm. It can be understood that the deviation x is the actual distance of the pre-swing of the pushing bed, and as the pushing bed pre-swings, the actual distance of the pre-swing of the pushing bed gradually decreases, and the running speed of the pushing bed also gradually changes, that is, different formulas are selected to calculate according to the comparison of x and e 0、e1、e2 according to the formula (1).
S20: and calculating to obtain the pre-swing prediction time of the pushing bed according to the pushing bed parameter information and the steel billet parameter information.
Specifically, in this embodiment, the pre-swing prediction time of the pushing bed is the time consumed for centering the pushing bed in place.
Specifically, in one embodiment, in a specific steel turning pass, since the size of the pushing bed and the size of the steel billet are known amounts, the parameter information of the pushing bed and the parameter information of the steel billet can be preset, the pre-swing distance of the pushing bed is calculated and obtained, and then the pre-swing prediction time of the pushing bed is calculated and obtained.
Specifically, in another embodiment, in order to widen the application of the pushing bed pre-swing control method, the pushing bed parameter information and the billet parameter information may be determined through device identification. Step S20, calculating to obtain a pushing bed pre-swing prediction time according to the pushing bed parameter information and the billet parameter information, including:
S21: and obtaining the steel turning direction of the billet on the roller way.
Specifically, the steel turning direction of the steel billet on the roller way is identified through a visual identification device. The visual recognition device comprises visual recognition equipment and a visual recognition model, the visual recognition equipment is used for collecting the billet image, and the visual recognition model is used for comparing the billet image at the previous moment with the billet image at the current moment, so that the steel turning direction of the billet on the roller way can be determined to be clockwise or anticlockwise. The visual recognition model can be obtained through training a large number of images in the steel turning process, can be used for recognizing the steel turning direction, and can also be used for recognizing the length and width of the steel billet and the actual opening size of the pushing bed.
Specifically, in another embodiment, the steel turning direction of the billet on the roller table may be preset according to the actual situation.
The direction of turning the steel is indicated by the arrow in fig. 3.
S22: and determining the dimension parallel to the axis of the roller way when the billet is turned in place according to the steel turning direction of the billet on the roller way, the length of the billet and the width of the billet.
Specifically, the length and width of the billet can be identified by the visual identification device. Referring to the rotating arrow of fig. 3, the billet enters a steel transferring pass, the length and the width of the billet can be identified through a visual identification device, meanwhile, the dimension parallel to the axis of the roller way is determined to be the length L, the steel transferring direction of the billet on the roller way is identified to be anticlockwise based on the visual identification device, and the dimension parallel to the axis of the roller way when the steel transferring is in place is determined to be the width W.
S23: and obtaining the pre-swinging distance of the pushing bed according to the parameter information of the pushing bed and the dimension parallel to the axis of the roller way when the steel billet is turned into place.
Specifically, the method comprises the following steps: and (3) differentiating the actual opening size of the pushing bed and the size parallel to the axis of the roller way when the steel billet is turned into place, and obtaining the pre-swinging distance of the pushing bed.
Specifically, the actual opening size of the pushing bed can be preset, and can be identified by a visual identification device, and it can be understood that the actual opening size of the pushing bed can also be obtained by measuring a sensor. The actual opening size of the pushing bed is in order to ensure that the billet can freely rotate.
S24: and determining the pre-swinging predicted time of the pushing bed according to the pre-swinging distance of the pushing bed and a preset pre-swinging time calculation model of the pushing bed.
Specifically, the method comprises the following steps: comparing the pushing bed pre-swing distance with a plurality of preset pre-swing distance ranges, and determining a pushing bed pre-swing time calculation model corresponding to the pushing bed pre-swing distance according to a mapping relation between the preset pre-swing distance ranges and the pushing bed pre-swing time calculation models;
And determining the pre-swinging prediction time of the pushing bed based on the pushing bed pre-swinging time calculation model corresponding to the pre-swinging distance of the pushing bed according to the actual opening size of the pushing bed, the running maximum speed of the pushing bed, the running minimum speed of the pushing bed and the size parallel to the axis of the roller way when the steel billet is turned into place.
Specifically, referring to fig. 3, before turning the steel billet into the steel, the pushing bed is opened to a position P where the steel billet can rotate freely, the opening size of the pushing bed at the position P is the actual opening size L P of the pushing bed, if the size parallel to the axis of the roller bed is the width W when the steel billet turns into the steel billet, the time required for the pushing bed to reach the deviation e 0 from the starting position P is calculated as the pre-swing prediction time t 1 of the pushing bed according to the formula (2) according to the change of the running speed of the pushing bed and the formula (1).
Specifically, the plurality of preset pendulum distance ranges according to formula (2) are a first preset pendulum distance range-greater than or equal to the deviation e 2, a second preset pendulum distance range-greater than or equal to the deviation e 1 and less than the deviation e 2, and a third preset pendulum distance range-greater than or equal to the deviation e 0 and less than the deviation e 1.
Specifically, the three pushing bed pre-swing time calculation models are in one-to-one correspondence with three preset pre-swing distance ranges, and after the preset pre-swing distance ranges are determined, the pushing bed pre-swing predicted time t 1 can be calculated and obtained according to the corresponding pushing bed pre-swing time calculation models.
S30: and calculating to obtain the steel billet turning in-place prediction time according to the roller way parameter information and the steel billet parameter information.
Specifically, step S30 includes:
S31: and calculating to obtain the angular speed of the billet under the current steel rotation angle according to the roller way parameter information and the billet parameter information.
Specifically, referring to fig. 3, in the process of turning the steel billet, as the contact position of the steel billet and the tapered roller way is continuously changed, the diameter of the contact position of the outer edge of the steel billet and the roller way is changed, and in order to accurately predict the turning time of the steel billet, the relationship between the angular velocity and other factors in the process of turning the steel billet is required to be determined.
Assuming that the length of the billet is L, the width of the billet is W, the included angle of the diagonal line of the billet is beta, the length of the roller way is L R, the diameter of the thin end of the roller way and the diameter of the thick end of the roller way of the conical roller way are d 1 and d 2 respectively, and the linear speed of the thin end of the conical roller way is V R. When the steel rotation angle is alpha, the calculation formula of the roller way diameter d at the contact position of the billet and the conical roller way is as follows:
wherein L 1 is the projection of the billet diagonal line in the axial direction of the roller way, and is calculated by the formula (4).
The horizontal linear velocity V P at the contact position of the billet and the conical roller way is as follows:
The angular velocity w of the billet at the current billet rotation angle alpha is thus obtained as follows:
S32: and calculating to obtain the in-place steel turning prediction time of the steel billet according to the angular speed of the steel billet under the current steel turning angle and the current steel turning angle of the steel billet.
Specifically, as the steel turning angle gradually approaches the in-place angle, the roller way gradually decelerates to ensure that the speed of the steel billet after turning in place is close to 0. In order to achieve the minimum steel turning time, the optimal roller speed control strategy is to accelerate the roller speed to the maximum as much as possible, then decelerate the roller speed to 0, and gradually decelerate the roller by considering the slope setting of the roller speed curve, and the ideal steel turning ending condition is that when the feedback speed of the roller is 0, the steel billet is turned to 90 degrees. In the process of reducing the speed of the roller way, the slope of the speed curve of the roller way is a fixed value, so that the speed average value from the actual steel position to the steel position can be used for calculating the steel billet steel position-rotating prediction time when the actual steel position is rotated.
Assuming that the steel billet turning in-place prediction time is t 2, according to the obtained angular speed of the steel billet under the current turning angle, turning the steel billet to the turning angle 90 degrees, and predicting the steel billet turning in-place prediction time to be t 2 according to the difference value between the turning angle 90 degrees and the turning angle alpha, as shown in the formula (7).
S40: and controlling the pre-swing of the pushing bed according to the pre-swing prediction time of the pushing bed and the steel billet turning in-place prediction time so as to ensure that the time difference between the turning in-place moment and the centering in-place moment of the pushing bed is within a preset range.
In particular, in ideal cases, when the steel turning time and the centering time of the pushing bed are the same time, the time consumption of steel turning passes can be shortened to the greatest extent. In practical application, the time difference between the steel turning in-place moment and the centering in-place moment of the pushing bed is within a preset range, so that the waiting time of the pushing bed in the centering process is reduced, the efficiency of the steel turning process is further improved, and the production efficiency is improved.
Specifically, in step S40, according to the pre-swing prediction time of the pushing bed and the steel billet turning in-place prediction time, the pre-swing of the pushing bed is controlled so that a time difference between a turning in-place moment and a centering in-place moment of the pushing bed is within a preset range, including:
When the time difference between the pushing bed pre-swing prediction time and the steel billet turning in-place prediction time is smaller than or equal to a preset time delta t, controlling the pushing bed to pre-swing as shown in a formula (8):
Wherein t 1 is the pre-swing prediction time of the pushing bed; and t 2 is the steel billet turning in-place prediction time.
Specifically, in this embodiment, specifically, if some abnormal conditions occur in the steel billet during the steel turning process, such as when the steel billet slips and is blocked by the roller table, the steel turning angle α will be abnormal, and at this time, a steel turning fault early warning needs to be performed to control to cancel the automatic pre-swing instruction of the pushing bed, so as to avoid interference caused by turning steel, and perform centering after the steel billet is adjusted. The method for judging the steel transformation fault comprises the following steps:
acquiring a steel turning angle at the previous moment and a steel turning angle at the current moment;
and comparing the steel turning angle at the previous moment with the steel turning angle at the current moment, and judging the steel turning fault when the difference between the steel turning angle at the previous moment and the steel turning angle at the current moment is smaller than a preset difference range.
Specifically, when phenomena such as steel billet slipping and steel billet being clamped by a roller way occur, the steel turning angle at the previous moment and the steel turning angle at the current moment are not changed or the change amount is small, namely the difference value between the steel turning angle at the previous moment and the steel turning angle at the current moment is smaller than the preset difference value range, and at the moment, the steel turning fault can be judged.
Therefore, in the scheme, the method calculates the pre-swing prediction time of the pushing bed and the steel billet in-place prediction time of the steel billet, controls the pushing bed to pre-swing so that the time difference between the steel billet in-place moment and the centering in-place moment of the pushing bed is within a preset range, realizes the matching and fusion of the steel billet in-place rotation and the centering in-place of the pushing bed, reduces the waiting time of the pushing bed in the centering process, further improves the efficiency of the steel billet in-place process and improves the production efficiency.
It should be understood that the sequence number of each step in the foregoing embodiment does not mean that the execution sequence of each process should be determined by the function and the internal logic, and should not limit the implementation process of the embodiment of the present invention.
