Description

Technical Field

[0001] This invention relates to the field of tire manufacturing technology, and in particular to a method for improving the quality of all-steel hot-press cutting. Background Technology

[0002] As a core component of commercial vehicles and construction machinery, the all-steel radial tire's production process, particularly the hot-bonding cutting process, directly determines the bonding precision between the hot-bonded rubber core and the tire carcass. This, in turn, affects the tire's airtightness, structural strength, and service life. The temperature control precision and service life of the cutting blade are key factors in ensuring the quality of this process and represent a crucial aspect of tire manufacturing technology.

[0003] Currently, the existing technical solutions for all-steel hot-press cutting in the industry are as follows: The cutting blade adopts a control logic of heating upon return and stopping heating upon descent. That is, the cutting blade enters the heating state when it returns to the initial zero position from the cutting position, and the heating operation stops immediately when the cutting blade falls from the zero position into the cutting process. However, the cutting blade only heats when returning to the position and stops heating when it falls to cut, and there is no temperature fluctuation compensation measure. The cutting blade is in a state of repeated high temperature and low temperature fluctuation for a long time, which accelerates the wear of the cutting blade. In addition, the cutting blade continuously consumes temperature due to contact with the material, but there is no targeted temperature replenishment, resulting in insufficient temperature at the cutting end, and quality problems such as uneven bottom cutting and edge burrs. Summary of the Invention

[0004] This invention provides a method for improving the cutting quality of all-steel hot-stamping, in order to solve the problem of unstable cutting quality caused by temperature consumption during the cutting process in the prior art.

[0005] On one hand, the present invention provides a method for improving the quality of all-steel hot-press cutting, comprising: The preset temperature, temperature loss prediction parameters, temperature compensation limit range, and adjacent state transition trigger conditions based on preset position thresholds are set for the multiple motion states of the cutting blade. Continuously collect data on the cutting position, cutting speed, cutting tip temperature, and heating power of the cutting blade; When the cutting blade is in the first motion state and the cutting blade position reaches the preset position threshold corresponding to the first motion state, a temperature prediction calculation is triggered to calculate the transition time and temperature loss of the cutting blade to the second motion state. Based on the transition time and the amount of temperature loss, a predicted temperature for the second motion state is generated; The predicted temperature is compared with the preset temperature corresponding to the second motion state to generate a temperature compensation value within the temperature compensation limit range. A heating power adjustment command is generated based on the temperature compensation value, and the heating power adjustment command is converted into a heating control signal to dynamically correct the temperature at the end of the cutting blade after the cutting blade enters the second motion state.

[0006] Optionally, preset temperatures, temperature loss prediction parameters, temperature compensation limits, and adjacent state transition triggering conditions based on preset position thresholds are defined for the various cutting blade motion states, including: The cutting characteristics of the cutter under different motion states were analyzed, and the preset temperature corresponding to the multiple motion states of the cutter was determined by combining the material properties of the all-steel heat-sealing plate. Based on the temperature change data during the historical operation of the cutting blade, a correlation between temperature loss and motion parameters is established, and temperature loss prediction parameters are set according to the correlation. Based on the safe operating range of the cutting blade and the cutting quality requirements, the temperature compensation limit range is defined; A preset position threshold is set on the cutting blade's movement path as a trigger point for the transition between adjacent states.

[0007] Optionally, continuously collect data on the cutting position, cutting speed, cutting tip temperature, and heating power of the cutting blade, including: The position of the cutting blade is obtained by a position detection sensor that is linked to the moving parts of the cutting blade. The cutting speed is obtained by monitoring the operating parameters of the cutting blade drive device; The end of the cutter is thermally imaged using an infrared thermal imager, and the temperature of the cutter end is collected based on the grayscale value of the thermal image. The heating power is calculated by monitoring the electrical parameters of the cutting tool's heating circuit.

[0008] Optionally, generating a predicted temperature for the second motion state based on the transition time and the amount of temperature loss includes: Take the first end temperature of the cutting blade in the first motion state; Based on the temperature loss prediction parameters and the first end temperature, the initial predicted temperature when the cutter enters the second motion state is obtained; Taking into account the cumulative effect of the transition time on temperature loss, the initial predicted temperature is corrected to generate the predicted temperature of the second motion state.

[0009] Optionally, the predicted temperature is compared with the preset temperature corresponding to the second motion state to generate a temperature compensation value within the temperature compensation limit range, including: Calculate the difference between the predicted temperature and the preset temperature of the second motion state; determine the temperature compensation direction and preliminary compensation amount based on the sign and absolute value of the difference; Determine whether the initial compensation amount is within the temperature compensation limit range. If the initial compensation amount exceeds the temperature compensation limit range, then based on the temperature compensation direction, use the boundary value of the temperature compensation limit range as the temperature compensation value.

[0010] Optionally, the method further includes calculating the difference between the predicted temperature and the preset temperature of the second motion state; and determining the temperature compensation direction and preliminary compensation amount based on the sign and absolute value of the difference. Collect cutting environment data of the cutter, including temperature, humidity and airflow speed data; The environmental impact coefficient is calculated based on the difference between the cutting environment data and the preset environmental benchmark value. Multiplying the environmental impact coefficient by the preliminary compensation amount yields the environmentally corrected preliminary compensation amount.

[0011] Optionally, a heating power adjustment command is generated based on the temperature compensation value, and the heating power adjustment command is converted into a heating control signal to dynamically correct the temperature at the end of the cutting blade after the cutting blade enters the second motion state, including: Based on the magnitude and direction of the temperature compensation value, the adjustment range and direction of the heating power are determined, and a heating power adjustment command is generated. The heating power adjustment command is converted into a heating control signal adapted to the cutting knife heating device, so as to adjust the output power of the cutting knife heating device; When the cutting blade enters the second motion state, the end temperature is compared with the preset temperature to obtain the temperature deviation; The temperature compensation value is calculated based on the temperature deviation, and the heating control signal is updated until the cutting blade completes the cutting operation in the second motion state.

[0012] Optional, also includes: After the cutting blade completes the cutting operation, the cutting edge quality data of the all-steel hot-pressed sheet is collected; The quality data of the cut edge is compared with the preset quality standard to obtain the quality deviation value; The temperature loss prediction parameters are corrected based on the mass deviation value.

[0013] Optional, also includes: When the cutting blade is detected to be not in the zero position, the output of the heating control signal is stopped.

[0014] Optional, also includes: When the heating power adjustment command is converted into the heating control signal, the programmable logic controller is programmed through several analog output components, so that the heating control signal is transmitted to the cutting knife heating device through the analog output components.

[0017] On the other hand, the present invention also provides a computer program product, including a computer program that, when executed by a processor, implements the all-steel hot-press cutting quality improvement method as described above.

[0018] The method for improving the cutting quality of all-steel hot-press cutting provided by this invention involves pre-setting preset temperatures, temperature loss prediction parameters, temperature compensation limits, and adjacent state transition triggering conditions based on preset position thresholds for multiple movement states of the cutting blade. It continuously collects data on the cutting blade position, cutting blade speed, cutting blade end temperature, and heating power. When the cutting blade transitions from the first movement state to the second movement state, it calculates the temperature loss in advance and generates a predicted temperature. Then, it adjusts the heating power through temperature compensation values ​​to ensure that the end temperature of the cutting blade meets the preset requirements when it enters the second movement state. This solves the problem of unstable cutting quality caused by temperature loss during the all-steel hot-press cutting process. Attached Figure Description

Obviously, the drawings described below are some embodiments of this invention. For those skilled in the art, other drawings can be obtained from these drawings without creative effort.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0022] Figure 1 This is a flowchart illustrating the method for improving the quality of all-steel hot-press cutting provided in an embodiment of the present invention.

[0023] like Figure 1 As shown, the method for improving the cutting quality of all-steel hot-pressed sheets provided in this embodiment of the invention mainly includes the following steps: 101. Preset temperature, temperature loss prediction parameters, temperature compensation limit range, and adjacent state transition trigger conditions based on preset position thresholds for the pre-set multiple movement states of the cutting blade.

[0024] The preset temperature is the working temperature of the cutter set according to different cutting states and the material and thickness of the all-steel radial tire being cut. The preset temperature ensures cutting quality while avoiding cutting problems caused by overheating or undercooling of the cutter.

[0025] Temperature loss prediction parameters are used to predict the temperature loss of the cutting blade during the cutting process due to factors such as friction and heat dissipation. These parameters allow for dynamic adjustment of the heating power to maintain a stable cutting blade temperature.

[0026] The temperature compensation limit range is the allowable range of temperature compensation for the cutting blade, limiting the maximum value of temperature compensation.

[0027] The preset position threshold is used to determine when the cutter transitions from its current state to the next. When the cutter moves to the preset position threshold, the adjacent state transition trigger condition will be triggered, ensuring that the cutter smoothly switches states at the appropriate position and avoiding any impact on cutting quality.

[0028] Specifically, the preset temperature, temperature loss prediction parameters, temperature compensation limit range, and adjacent state transition trigger conditions based on preset position thresholds for the pre-set multiple movement states of the cutting blade include: By analyzing the cutting characteristics of the cutter under different motion states, and combining the material properties of the all-steel heat-sealing plate, the preset temperature corresponding to the multiple motion states of the cutter is determined.

[0029] Based on temperature change data during the historical operation of the cutting blade, a correlation between temperature loss and motion parameters is established, and temperature loss prediction parameters are set according to the correlation.

[0030] Based on the safe operating range of the cutting blade and the cutting quality requirements, the temperature compensation limit range is defined.

[0031] Set a preset position threshold on the cutting tool's motion path as the trigger point for the transition between adjacent states.

[0032] Among them, when setting the preset temperature, temperature loss prediction parameters, temperature compensation limit range, and adjacent state transition trigger conditions based on the preset position threshold for the multi-level movement states of the cutting blade, the cutting characteristics of the cutting blade in different levels of movement states such as fast, slow, and micro speed will be analyzed first. For example, the difference in temperature requirements for cutting force and contact time with material will be considered. At the same time, the thickness of the rubber core and the heat resistance of the material of the all-steel heat-bonded adhesive will be combined to determine the preset temperature of the cutting blade to adapt to the cutting requirements in each level of movement state.

[0033] Next, based on the temperature change data corresponding to different motion parameters recorded during the historical operation of the cutter, a correlation between temperature loss and motion parameters is established through statistical analysis, and temperature loss prediction parameters are set according to the correlation for subsequent temperature prediction. Then, combined with the safe operating temperature range that the cutter material itself can withstand, as well as the quality requirements of flat and burr-free hot-press cutting of all-steel, a comprehensive temperature compensation limit range is defined to ensure that the compensated temperature is within the safe range and meets the cutting quality standards.

[0034] Finally, at critical path nodes where the cutter switches from one motion state to another, such as the path position where it transitions from fast approach to slow positioning or from slow positioning to micro-speed precision cutting, a preset position threshold is set. This preset position threshold is used as the trigger point for the transition between adjacent motion states of the cutter, so that the temperature prediction and power adjustment process can be triggered through position detection.

[0035] 102. Continuously collect data on the cutting position, cutting speed, cutting tip temperature, and heating power of the cutting blade.

[0036] The system ensures data accuracy and timeliness by collecting various operational parameters of the cutting blade in real time. Blade position information is used to accurately locate the blade's specific position during the cutting process, while blade speed reflects the blade's movement state. The temperature at the blade tip is directly related to the cutting effect and the degree of material thermal damage, and heating power is the primary means of controlling the blade temperature.

[0037] Specifically, the cutting position, cutting speed, cutting tip temperature, and heating power of the cutting blade are continuously collected, including: The position of the cutting blade is obtained by a position detection sensor that is linked to the moving parts of the cutting blade. The cutting speed is obtained by monitoring the operating parameters of the cutting blade drive device; The end of the cutting blade is thermally imaged using an infrared thermal imager, and the temperature of the cutting blade end is collected based on the grayscale value of the thermal image. The heating power is calculated by monitoring the electrical parameters of the cutting tool's heating circuit.

[0038] In obtaining the position of the cutting blade, the position detection sensor is directly linked to the moving parts of the cutting blade, so that the position detection sensor can capture the position signal synchronously with the movement of the cutting blade. For example, the position detection sensor can output an electrical signal by sensing the displacement change of the moving parts, and then directly obtain the real-time position data of the cutting blade in different movement states, providing data support for subsequent judgment on whether the cutting blade has reached the preset position threshold.

[0039] When obtaining the cutting speed, the operating parameters of the cutting drive device are monitored, and a preset conversion logic is used, such as calculating the actual movement speed of the cutting blade based on the motor speed and the reduction ratio of the transmission mechanism. The operating parameters of the cutting drive device are then converted into real-time speed data of the cutting blade. The cutting speed can be used to calculate the transition time of the cutting blade between adjacent movement states.

[0040] When acquiring the temperature of the cutting blade tip, an infrared thermal imager is installed at a fixed position in the cutting area of ​​the blade. The imager lens is aimed at the cutting part of the blade tip to perform real-time thermal imaging scanning. At the same time, based on the pre-established correspondence between thermal imaging grayscale values ​​and temperature, the grayscale values ​​in the thermal imaging image are converted into real-time temperature data of the cutting blade tip. This effectively avoids the problem of traditional contact temperature measurement being easily affected by vibration, ensures the accuracy of tip temperature monitoring, and provides an accurate basis for temperature compensation calculation.

[0041] When obtaining heating power, the cutter collects electrical parameters such as the operating current and voltage of the heating circuit in real time by connecting a current sensor in series and a voltage sensor in parallel in the cutting cutter heating circuit. Then, it uses the power calculation formula to calculate the actual heating power of the cutter in real time. The heating power can be used to determine whether the current heating state matches the temperature compensation requirements.

[0042] 103. When the cutting blade is in the first motion state and the cutting blade position reaches the preset position threshold corresponding to the first motion state, the temperature prediction calculation is triggered to calculate the transition time and temperature loss of the cutting blade to the second motion state.

[0043] Specifically, the position data of the cutting blade is acquired by the position detection sensor, and the cutting blade position data is compared in real time with the preset position threshold corresponding to the first motion state, such as the key points of the path when the cutting blade transitions from the fast approach state to the slow positioning state. At the same time, the current motion state indicator of the cutting blade is monitored to confirm whether the cutting blade is in the first motion state.

[0044] When both conditions are met—that is, the cutter is in the first motion state and its real-time position reaches a preset position threshold—temperature prediction calculation is performed. The transition time and temperature loss of the cutter to the second motion state are calculated. Specifically, when calculating the transition time, the current speed of the cutter, obtained from the operating parameters of the cutter drive device, is combined with the pre-stored path distance from the end point of the first motion state to the start point of the second motion state. The formula `transition time = path distance / current speed` is used to calculate the transition time required for the cutter to move from the first motion state to the second motion state.

[0045] When calculating the temperature loss, the preset temperature loss prediction parameters and transition time, as well as the current end temperature data of the cutter, are used to calculate the temperature loss caused by the natural heat dissipation of the cutter during the transition stage using the preset temperature loss calculation formula. The temperature loss calculation formula is: Temperature loss = Temperature loss prediction parameters × Transition time × Current temperature influence coefficient.

[0046] It is understandable that the first motion state and the second motion state are two consecutive motion states.

[0047] 104. Based on the transition time and temperature loss, generate the predicted temperature of the second motion state.

[0048] The predicted temperature is the temperature expected when the cutter moves from its current position to the next operating state. This predicted temperature will serve as the temperature reference when the cutter enters the second operating state. By calculating the predicted temperature, the output power of the cutter heating device can be adjusted in advance to ensure that the cutter reaches the predetermined temperature range in the second operating state, thereby maintaining stable cutting quality and efficiency.

[0049] Specifically, based on the transition time and temperature loss, the predicted temperature of the second motion state is generated, including: Obtain the first end temperature of the cutting blade in its first motion state; Based on the temperature loss prediction parameters and the first end temperature, the initial predicted temperature when the cutter enters the second motion state is obtained. By taking into account the cumulative effect of transition time on temperature loss, the initial predicted temperature is corrected to generate the predicted temperature for the second motion state.

[0050] Specifically, an infrared thermal imager is used to monitor the temperature of the cutting blade tip in the first motion state in real time, obtaining the first tip temperature of the cutting blade tip in the first operating state. Then, based on pre-set temperature loss prediction parameters and combined with the first tip temperature, the initial predicted temperature when the cutting blade initially enters the second motion state is obtained through a preset basic loss calculation logic. The initial predicted temperature takes into account the heat loss of the cutting blade from the first motion state to the second motion state.

[0051] Finally, since there is a certain transition time between the cutting blade's first motion state and the second motion state, and the longer the transition time, the more temperature loss accumulates due to continuous heat dissipation, it is necessary to combine the transition time and calculate the cumulative temperature loss during the transition stage using the calculation logic of cumulative loss = temperature loss prediction parameter × transition time. Then, the initial predicted temperature is subtracted from the cumulative loss to correct the initial predicted temperature, and finally, the predicted temperature of the second motion state that fits the actual heat dissipation situation is generated, avoiding problems such as uneven cutting edges caused by inaccurate temperature prediction.

[0052] 105. Compare the predicted temperature with the preset temperature corresponding to the second motion state to generate a temperature compensation value within the temperature compensation limit range.

[0053] The temperature compensation value is the temperature difference that the cutter needs to adjust in the second movement state. If the predicted temperature is lower than the preset temperature, the temperature compensation value is positive, indicating that the cutter temperature needs to be increased. By calculating the temperature compensation value, it can be ensured that the cutter maintains its working temperature in the second movement state, thereby significantly improving the cutting quality of the all-steel hot-pressed sheet and avoiding defects on the cutting edge due to improper temperature.

[0054] Specifically, the predicted temperature is compared with the preset temperature corresponding to the second motion state to generate a temperature compensation value within the temperature compensation limit range, including: Calculate the difference between the predicted temperature and the preset temperature of the second motion state; determine the direction of temperature compensation and the initial compensation amount based on the sign and absolute value of the difference; Determine whether the initial compensation amount is within the temperature compensation limit range. If the initial compensation amount exceeds the temperature compensation limit range, then based on the temperature compensation direction, use the boundary value of the temperature compensation limit range as the temperature compensation value.

[0055] The temperature difference between the predicted temperature of the second motion state and the preset temperature of the second motion state is calculated using a difference calculation formula. The temperature difference reflects the degree of temperature deviation when the cutter enters the second motion state.

[0056] Next, the direction of temperature compensation is determined based on the sign of the difference. If the difference is positive, it means that the predicted temperature is higher than the preset temperature, and a cooling compensation direction needs to be set. If the difference is negative, it means that the predicted temperature is lower than the preset temperature, and a heating compensation direction needs to be set. At the same time, the initial compensation amount is determined based on the absolute value of the difference.

[0057] Finally, based on the preset temperature compensation range, it is determined whether the initial compensation amount falls within this range. If the initial compensation amount is within the range, it is directly used as the temperature compensation value. If the initial compensation amount exceeds the range, the corresponding boundary value of the temperature compensation range is taken as the final temperature compensation value according to the previously determined temperature compensation direction, to avoid abnormal fluctuations in the cutting blade temperature due to excessive compensation. For example, if the initial compensation amount is 45℃, exceeding the upper limit of the temperature compensation range of 0-40℃, then the temperature compensation value is 40℃.

[0058] Furthermore, in some embodiments, the difference between the predicted temperature and the preset temperature of the second motion state is calculated; after determining the temperature compensation direction and preliminary compensation amount based on the sign and absolute value of the difference, the method further includes: Collect cutting environment data for the cutting blade, including temperature, humidity, and airflow speed data; The environmental impact coefficient is calculated based on the difference between the cut environmental data and the preset environmental benchmark value. Multiply the environmental impact factor by the preliminary compensation amount to obtain the preliminary compensation amount after environmental correction.

[0059] In this process, after calculating the difference between the predicted temperature and the preset temperature of the second motion state, and determining the direction and initial compensation amount of temperature compensation based on the sign and absolute value of the difference, the initial compensation amount needs to be further optimized using environmental data, considering that the cutting environment directly affects the heat dissipation rate of the cutting blade. For example, real-time cutting environment data of the cutting area of ​​the cutting blade is first collected through an environmental monitoring component, including ambient temperature, humidity, and airflow speed. Then, each collected environmental data is compared with a preset environmental benchmark value, and the difference between each environmental data and the corresponding benchmark value is calculated. If the ambient temperature is lower than the benchmark value or the airflow speed is higher than the benchmark value, the heat dissipation rate of the cutting blade will be faster than ideal, and the difference directly reflects the degree of heat dissipation deviation.

[0060] Next, the environmental impact coefficient is determined based on the magnitude of the difference. For example, the larger the difference, the more the environmental impact coefficient deviates from 1. When heat dissipation is accelerated, the environmental impact coefficient is set to a value greater than 1 to amplify the compensation force and offset the additional heat dissipation.

[0061] Finally, the environmental impact coefficient is multiplied by the initial compensation amount to obtain the environmentally corrected initial compensation amount. This ensures that the compensation amount can adapt to the heat loss under the actual cutting environment and avoids the temperature from deviating from the preset value after the cutter enters the second motion state due to environmental fluctuations.

[0062] 106. Generate a heating power adjustment command based on the temperature compensation value, and convert the heating power adjustment command into a heating control signal to dynamically correct the temperature at the end of the cutting blade after the cutting blade enters the second motion state.

[0063] The temperature compensation value is a temperature adjustment amount derived by comprehensively considering the initial temperature deviation of the cutting blade, changes in its motion state, and the influence of the cutting environment. The heating power adjustment command is set based on the temperature compensation value, controlling the temperature at the end of the cutting blade by adjusting the power output of the heating element. The heating power adjustment command is processed by the conversion module and converted into a heating control signal. This signal directly acts on the cutting blade's heating system, ensuring a rapid and accurate response when the cutting blade enters its second motion state, dynamically correcting the temperature at the end of the cutting blade to the preset ideal range, effectively preventing cutting quality problems caused by temperature fluctuations.

[0064] Specifically, a heating power adjustment command is generated based on the temperature compensation value, and this command is converted into a heating control signal. After the cutting blade enters the second motion state, the temperature at the end of the cutting blade is dynamically corrected, including: Based on the magnitude and direction of the temperature compensation value, determine the adjustment range and direction of the heating power, and generate a heating power adjustment command; The heating power adjustment command is converted into a heating control signal adapted to the cutting knife heating device, so as to adjust the output power of the cutting knife heating device; Once the cutting blade enters the second motion state, the end temperature is compared with the preset temperature to obtain the temperature deviation. The temperature compensation value is calculated based on the temperature deviation, and the heating control signal is updated until the cutting blade completes the cutting operation in the second motion state.

[0065] Based on the specific magnitude and direction of the temperature compensation value, the adjustment range and direction of the heating power are determined through a preset compensation value power conversion logic, generating a precise heating power adjustment command to ensure that the power adjustment can accurately match the temperature compensation requirements and avoid power deviation caused by manual setting of the original potentiometer.

[0066] Next, the heating power adjustment command is converted into a heating control signal that is compatible with the cutting knife heating device. For example, this can be achieved through an analog output module, replacing relay on / off control, effectively avoiding the power fluctuation problem caused by frequent relay switching, and enabling the heating control signal to be stably transmitted to the cutting knife heating device to directly adjust the output power of the cutting knife heating device.

[0067] Once the cutting blade enters the second motion state, the temperature at the end of the cutting blade is collected in real time by an infrared thermal imager. The temperature at the end of the cutting blade is compared in real time with the preset temperature corresponding to the second motion state, and the temperature difference between the two is calculated to obtain the temperature change caused by heat consumption during the cutting process.

[0068] Finally, the corresponding temperature compensation value is recalculated based on the calculated temperature deviation, and the heating control signal is updated based on the new compensation value. The dynamic correction process of comparing temperature difference, calculating new compensation value, and updating control signal is repeatedly executed until the cutter completes the cutting operation in the second motion state. This solves the problem of unstable cutting quality caused by temperature consumption during the cutting process, and ensures that the temperature of the cutter is consistent with the preset requirements throughout the process. This not only improves the flatness of the cutting edge to reduce the waste of the glue core, but also reduces the wear of the cutter due to the stable temperature, extending its service life. At the same time, it avoids equipment downtime caused by the failure of the original relay or potentiometer, ensuring production continuity.

[0069] In some embodiments, the method for improving the quality of all-steel hot-press cutting provided by the present invention further includes: After the cutting blade completes the cutting operation, the cutting edge quality data of the all-steel hot-pressed sheet is collected; The quality data of the cut edge is compared with the preset quality standard to obtain the quality deviation value; The temperature loss prediction parameters are corrected based on the quality deviation value.

[0070] The process involves collecting edge quality data of the hot-pressed steel strip after each single or batch cutting operation. This data includes edge flatness and burr length. The edge quality data is then compared with preset cutting quality standards to identify the deviation. Finally, the set temperature loss prediction parameters are adjusted based on this deviation. For example, if the deviation indicates microburrs due to slightly lower temperatures, the temperature loss prediction parameters can be adjusted to increase temperature compensation in subsequent cutting operations, making the prediction parameters more closely match the actual cutting conditions and further ensuring stable cutting quality.

[0071] In some embodiments, the method for improving the quality of all-steel hot-press cutting provided by the present invention further includes: When the cutting blade is detected to be not at the zero position, the output of the heating control signal will stop.

[0072] Specifically, when the cutting blade starts operating, it monitors whether the current position of the cutting blade is at the initial zero position. If the monitoring result shows that the cutting blade is not at the zero position, the interruption mechanism of the heating control signal will be triggered immediately, and the output of the heating control signal to the cutting blade heating device will be stopped. By setting the zero position detection, the overheating wear caused by the continuous heating of the cutting blade in a non-zero position state can be effectively avoided, and the equipment safety hazards caused by unexpected heating can be prevented.

[0073] In some embodiments, the method for improving the quality of all-steel hot-press cutting provided by the present invention further includes: When the heating power adjustment command is converted into a heating control signal, the programmable logic controller is programmed through several analog output components, so that the heating control signal is transmitted to the cutting knife heating device through the analog output components.

[0074] In the process of converting heating power adjustment commands into heating control signals, several analog output components are first added, and then the programmable logic controller is programmed accordingly. This allows the generated heating control signals to be transmitted directly to the cutting blade heating device through the analog output components instead of relays, avoiding power fluctuations caused by relay switching. It also solves the problem of poor contact when manually setting power with relays, enabling more precise control of the cutting blade heating temperature. This ensures the temperature stability of the cutting blade under various motion states, thereby improving cutting quality and extending the cutting blade's lifespan.
