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 billet into steel, the pushing bed is opened to a position P where the billet can rotate freely, and the opening size of the pushing bed at the position P is the actual opening size of the pushing bedL P Assuming that the dimension parallel to the roller axis is the width W when the billet is turned into place, the variation of the running speed of the pushing bed and the formula (1) can be obtained, and the pushing bed reaches the deviation from the initial position Pe 0 The required time is the pre-swing prediction time of the pushing bedt 1 And (3) calculating according to a formula (2).

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 can be calculated and obtained according to the corresponding pushing bed pre-swing time calculation modelst 1 。
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 isLWidth ofWThe included angle of the diagonal line of the billet isβThe length of the roller way isL 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 respectivelyd 1 Andd 2 the linear speed of the thin end of the conical roller way isV R . When the steel is turned to an angle ofαDuring the process, the roller way diameter calculation formula at the contact position of the billet and the conical roller way is as follows:
wherein,L 1 in the axial direction of the roller way for the diagonal line of the billetProjection, calculated from equation (4).
Horizontal linear velocity at contact position of billet and conical roller wayV P The method comprises the following steps:
thereby obtaining the current steel turning angle of the steel billetαAngular velocity of the lower partwThe method comprises the following steps:
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.
Assume that the steel billet turning in-place prediction time ist 2 According to the obtained angular velocity of the billet under the current turning angle, turning the billet to 90 degrees, and turning the billet to 90 degrees and turning the billet to the angleαThe difference value of (2) is estimated to be the steel turning in-place prediction time of the steel billett 2 As in equation (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 pre-swing predicted time of the pushing bed and the steel billet turning in-place predicted time is less than or equal to the preset time deltatAnd controlling the push bed to swing in advance as shown in a formula (8):
wherein,t 1 predicting time for the pre-swing of the pushing bed;t 2 predicting the time for turning the steel billet into place.
Specifically, in this embodiment, if some abnormal conditions occur in the process of turning the steel billet, such as slipping of the steel billet, jamming of the steel billet by the roller table, etc., the steel is turned to an angleαAbnormal changes occur, and at the moment, steel turning fault early warning is needed to control cancellation of automatic pre-swing instructions of the pushing bed, interference to steel turning is avoided, and centering is performed after steel billet adjustment is completed. 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 pushing bed pre-swing prediction time and the steel billet steel turning in-place prediction time are calculated, and the pushing bed pre-swing is controlled, so that the time difference between the steel turning in-place moment and the pushing bed centering in-place moment is within a preset range, the matching fusion of the steel billet steel turning in-place and the pushing bed centering in-place is realized, 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.
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.
