Description
Technical Field
[0001] This invention relates to the field of metallurgical automation control technology, specifically to a high-speed steel splitting system and method based on coordinated control of shearing timing. Background Technology
[0002] With the development of modern steel industry towards higher speeds and greater precision, the final rolling speed of high-speed wire rod and bar mills has generally exceeded 100 m / s. At such high speeds, accurately cutting and distributing continuously rolled steel to different collection channels (i.e., steel sorting) is the most prone to failure in the entire production line. Traditional steel sorting systems typically employ mechanical follow-up control, where the flying shear is only responsible for cutting the steel to a fixed length, and the cut steel head flies in a straight line due to inertia. The downstream steel sorter needs to complete the mechanical action switch within a very short time (usually only tens of milliseconds) before the steel head arrives.
[0003] However, existing passive steel-separating methods have extremely low fault tolerance. If the steel separator's movement is slightly delayed or there is even a tiny irregular movement of the steel head, the high-speed steel head is very likely to collide with the tip of the steel separator, leading to serious steel pile-up accidents and even equipment damage. Secondly, relying solely on mechanical steel separators requires extremely high hydraulic response speeds, resulting in high equipment costs and difficult maintenance. Some existing improvement schemes attempt to introduce high-speed cameras for monitoring, but these are mostly used for post-event alarms and lack active intervention methods. Therefore, it is essential to design a practical, highly efficient, and intelligent high-speed steel-separating system and method based on coordinated control of shearing timing.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0019] Example 1 Please see Figure 1 This invention provides a technical solution: a high-speed steel splitting method based on coordinated control of shearing timing, comprising the following steps: S101. Establish a multi-dimensional coupled spatiotemporal coordinate system between the flying shear machine and the steel separator; In this embodiment of the invention, a global reference coordinate system is established with the center of the flying shear blade as the zero point, the center line of the rolling line as the X-axis, and the plane perpendicular to the rolling line as the Y-axis. By collecting the real-time frequency of the main motor encoder Real-time calculation of steel head position Its solution expression is: ,in For the encoder's real-time frequency, This is the roller diameter conversion factor.

The clock deviation compensation formula is as follows: ,in Main site timestamp Uses the slave station's timestamp to automatically compensate for transmission delays.
[0021] S102. Based on the steel material model, predict the deformation trend of the shear fracture surface and generate the optimal differential shearing timing and steel separation guidance strategy. Specifically, in this embodiment of the invention, the current rolling mill set speed is obtained. Actual speed and steel temperature ; The target deflection angle is calculated based on the temperature-yield strength curve of the steel. Required shear stress difference ; Based on the current rolling speed, calculate the required difference in linear velocity between the upper and lower shear blades at the biting point. The calculation formula is as follows: ; in Mechanical structure gain coefficient For temperature sensitivity coefficient, The reference temperature; for example, if reference temperature Target deflection angle 3° Then calculate That is, the upper shear blade needs to be slower (or faster, depending on the direction) than the lower shear blade by approximately 10.66 m / s; In the formula, For geometric motion terms, we need to consider velocity. The running steel "bends" at an angle The required difference in linear velocity between the upper and lower surfaces is proportional to... . It is a correction factor that incorporates the mechanical and geometric effects of shear blade overlap and shear depth; For materials mechanics, is the temperature compensation factor; as the temperature decreases, the value within the parentheses will be greater than 1. This indicates that to bend the same angle in harder steel, a larger shear velocity difference (i.e., a larger shear torque) is required. Conversely, the hotter and softer the steel, the smaller the required velocity difference. Using the above formula, we can effectively analyze and calculate the instantaneous linear velocity difference between the upper and lower shear blade tips at the moment of cutting the steel, ensuring the steel head bends to the ideal angle.

Based on the parameters output by the deformation vector planner, the independent driving speed of the upper and lower shear blades is dynamically adjusted in real time, and the steel head is actively induced to generate a preset deflection angle at the moment of cutting. In this embodiment of the invention, the specific method for dynamically adjusting the independent driving speeds of the upper and lower shear blades in real time based on the parameters output by the deformation vector planner is as follows: Set the base speed of the upper and lower shear blades to ,in Forward rate; Based on the calculated difference in linear velocity required between the upper and lower shear blades at the engagement point Assign the target speed of the shear blade and the speed of the lower scissor blade target ; Dynamic torque feedforward compensation control is introduced to compensate for the inertial torque generated by acceleration and deceleration. The compensation formula is as follows: ,in Let the system's rotational inertia be... The coefficient of viscous friction, To dynamically feedforward compensate for torque, ensuring that during the shearing duration The internal velocity difference is constant; the arrow travels from bite to cut in just a few milliseconds, passing through... This indicates the establishment of a speed difference within this extremely short time, and the calculation of overcoming the rotational inertia of the motor and the drum. The required burst torque is needed to prevent deformation-induced failure caused by the steel being cut before the motor has a chance to accelerate.

Below the safety threshold.
[0027] Example 2 Embodiment 2 of the present invention provides a high-speed steel splitting system based on coordinated control of shearing timing. Figure 2 This is a schematic diagram of the module composition of the high-speed steel splitting system based on shearing timing coordinated control provided in Embodiment 2 of the present invention, as shown below. Figure 2 As shown, the system includes: The collaborative modeling unit is configured to establish a multi-dimensional coupled spatiotemporal coordinate system between the flying shear and the steel divider, and to analyze the mapping relationship between their motion states. The deformation vector planner is configured to calculate the optimal shear stress difference based on the rheological properties of steel, and generate differential commands for the dual-drive motors and timing strategies for the steel separator. The dual-drive differential response controller is configured to receive planner commands and independently adjust the speed and torque of the upper and lower shear blade motors to perform active deformation shearing. The transient rheological feedback module is configured to assess the deformation quality of the steel head through torque observation and visual capture; The collaborative execution control module is configured to dynamically correct the actions of the steel distributor based on feedback results, thereby completing the final distribution.
[0028] The transient rheological feedback module includes an energy integration calculation unit and a trajectory deviation analysis unit. The energy integration calculation unit is used to calculate the asymmetric power consumption during the shearing process in real time. The trajectory deviation analysis unit is used to compare the actual trajectory of the steel head with the theoretical safe trajectory and generate an avoidance trigger signal.
[0029] This application addresses the impact and steel piling problems that easily occur during steel separation on high-speed rolling production lines by providing an intelligent solution based on spatiotemporal coordination and active guidance. First, the system establishes a unified multi-dimensional coupled spatiotemporal coordinate system between the flying shear and the steel separator. Through a high-precision encoder and timestamp alignment algorithm, it eliminates timing deviations in high-speed movement, laying a foundation for precise control. Based on this, the system utilizes material rheological properties and real-time operating conditions to predict the deformation trend of the steel shear fracture surface and generate an optimal differential shearing strategy. This is not merely simple cutting; at the moment of cutting, by dynamically adjusting the independent drive speeds of the upper and lower shear blades, it actively creates a preset deflection angle at the steel head, utilizing the steel's own velocity and deformation potential energy to automatically slide it towards the target channel, thus reducing dependence on the mechanical movements of the steel separator from the source.
[0030] Furthermore, the system incorporates a dual closed-loop feedback mechanism during execution. On one hand, the deformation effectiveness index is calculated in real time using a shear energy asymmetric observer; on the other hand, a high-speed vision sensor captures the actual deflection angle of the steel head. This combination ensures the system can perceive the success of induced deformation in real time. If insufficient deformation or a risk of impact is detected, the system immediately triggers a rapid avoidance mode, forcing the steel separator to deviate from the steel head trajectory with maximum acceleration, achieving proactive defense. For example, in extreme conditions where the hardness of the steel fluctuates greatly, preventing the preset speed difference from generating sufficient deflection, or where the steel separator's response is lag-dependent, the system can quickly avoid steel accumulation through avoidance logic. Ultimately, this invention, through a dual guarantee mechanism of proactive induction and collaborative avoidance, achieves efficient and stable steel separation in ultra-high-speed rolling environments, significantly reducing equipment wear and maintenance costs.
