[0003] However, the existing disc shearing machines can only perform simple shearing and lack effective quality inspection means. It is difficult to timely discover and adjust the shearing action of the processed workpiece during the shearing process, resulting in quality problems in the workpiece obtained after processing, and further requiring additional quality inspection and / or rework processes to be set up later, increasing production costs and production cycles, and reducing shearing efficiency; at the same time, the disc used for shearing (for example: disc shears) will wear during use, and the wear of the disc cannot be observed intuitively, and due to the wear of the disc, the shearing depth of the workpiece will also change, so that the shearing quality will also be adversely affected, and then after the disc is worn, the initially set shearing depth value cannot meet the actual shearing quality requirements, and the shearing depth value can only be readjusted by manual experience, but the adjustment based on manual experience is greatly affected by subjective factors and cannot accurately guarantee the shearing quality of the disc; therefore, the existing disc shearing machines can no longer meet the actual production needs of high efficiency and high quality.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] The embodiment of the present invention provides a disc shearing machine, comprising: a frame assembly, a driving assembly, a transmission assembly, an upper cutter disc assembly, a lower cutter disc assembly, an adjustment assembly and a detection assembly; the driving assembly is connected to the upper cutter disc assembly and the lower cutter disc assembly through the transmission assembly, and the driving assembly is used to drive the upper cutter disc assembly and the lower cutter disc assembly to rotate; the transmission assembly is used to adjust the transmission ratio between the driving assembly and the upper cutter disc assembly and the lower cutter disc assembly; the upper cutter disc assembly and the lower cutter disc assembly are rotatably arranged on the frame assembly, respectively, so as to perform a shearing operation on the plate to be processed together; the adjustment assembly is connected to the upper cutter disc assembly and the lower cutter disc assembly, respectively, and is used to adjust the shearing depth of the plate to be processed by the upper cutter disc assembly and the lower cutter disc assembly; wherein the detection assembly is electrically connected to the driving assembly, the transmission assembly and the adjustment assembly, respectively; the detection assembly controls the driving assembly, the transmission assembly and the adjustment assembly to work accordingly by detecting the thickness of the plate to be processed, the edge position of the plate to be processed, the wear degree of the upper cutter disc assembly, the wear degree of the lower cutter disc assembly, and the shearing depth of the plate to be processed, so as to perform a shearing operation on the plate to be processed.

[0021] The present invention realizes real-time monitoring of the shearing process of the plate to be processed and detection of the shearing quality on the disc shearing machine by setting a frame assembly, a drive assembly, a transmission assembly, an upper cutter disc assembly, a lower cutter disc assembly, an adjustment assembly and a detection assembly to work together, so that quality problems that arise during the shearing process can be discovered in time, and quality problems that arise can be improved by adaptively adjusting the drive assembly, the transmission assembly, the upper cutter disc assembly, the lower cutter disc assembly and the adjustment assembly, thereby effectively reducing subsequent additional quality inspections and / or rework processes, reducing the shearing production cost and production cycle, and improving the shearing process efficiency; at the same time, the detection assembly detects the wear degree of the upper cutter disc assembly and the wear degree of the lower cutter disc assembly, thereby realizing real-time detection of the wear condition of the upper cutter disc assembly and the lower cutter disc assembly, and the adjustment assembly adjusts the initial distance between the upper cutter disc assembly and the lower cutter disc assembly. The present invention realizes compensation for the shearing depth error caused by wear of the upper and lower cutter disc components, thereby ensuring that the subsequent shearing quality effectively meets the actual shearing quality requirements after the disc is worn, without relying on manual experience to readjust the shearing depth, avoiding the adverse effects of subjective factors in manual adjustment, and thus ensuring the shearing quality of the plate to be processed; the present invention realizes real-time monitoring and automatic adjustment of the plate shearing process through an integrated detection component, ensures the stability and consistency of the shearing quality, further improves production efficiency and product quality, reduces manual intervention, and reduces production costs; on the whole, the present invention has a simple structure and low cost, is easy to assemble and subsequently maintain, and significantly improves the intelligence and automation level of the disc shearing machine in structure, bringing significant benefit improvement to the plate shearing field, and is suitable for large-scale promotion and use.

[0022] Specifically, the detection component includes: a sensor group, an image collector and a central controller; the sensor group, the image collector, the drive component, the transmission component and the adjustment component are electrically connected to the central controller respectively; the sensor group and the image collector can be used to detect the thickness of the plate to be processed, the edge position of the plate to be processed, the wear degree of the upper cutter disc component, the wear degree of the lower cutter disc component and the shearing depth of the plate to be processed; wherein the central controller compares and processes the data collected by the sensor group with the same data collected by the image collector to adjust the operation of the drive component, the transmission component and the adjustment component accordingly.

[0023] By setting up the specific structure of the detection component, the disc shearing machine can obtain real-time data of the plate to be processed and the upper and lower cutter disc components through two different detection methods. This analysis and comparison of multi-source data improves the reliability of the data and ensures the accuracy of adjusting the cutting depth of the plate, thereby improving the quality consistency of the sheared products and reducing the errors that may be caused by a single detection method.

[0024] Specifically, the image collector collects and analyzes image information of the plate to be processed before and after shearing, and calculates the shearing depth data of the plate to be processed, which is the first data; the sensor group detects the plate to be processed and obtains the shearing depth data of the plate to be processed, which is the second data. The central controller analyzes and processes the first data and the second data to obtain the actual shearing depth of the plate to be processed. The central controller compares the actual shearing depth of the plate to be processed with the target shearing depth to adjust the operation of the drive component, the transmission component and the adjustment component accordingly.

[0025] Through comprehensive analysis of image information and sensor data, the central controller can more accurately calculate the actual shearing depth of the plate to be processed. When a shearing depth deviation is detected, the central controller can adjust the drive component, transmission component and adjustment component to perform secondary shearing or mark unqualified plates, thereby effectively controlling the shearing accuracy, avoiding waste in subsequent processes, and improving overall production efficiency.

[0026] Optionally, when the depth difference between the actual shearing depth of the plate to be processed and the target shearing depth exceeds the allowable error range, and the actual shearing depth of the plate to be processed is less than the target shearing depth, the central controller controls the operation of the driving component, the transmission component and the adjusting component according to the depth difference, and performs secondary shearing on the plate to be processed according to the depth difference; and / or, when the depth difference between the actual shearing depth of the plate to be processed and the target shearing depth exceeds the allowable error range, and the actual shearing depth of the plate to be processed is greater than the target shearing depth, the central controller determines that the plate to be processed is an unqualified plate; and / or, when the depth difference between the actual shearing depth of the plate to be processed and the target shearing depth exceeds the set value, the central controller controls the adjusting component to adjust the initial distance between the upper and lower cutter disc assemblies according to the depth difference, combined with the wear degree data of the upper and lower cutter disc assemblies detected by the sensor group and the image collector, so as to compensate for the shearing depth error caused by the wear of the upper and lower cutter disc assemblies.

[0027] Through the above settings, when dealing with the deviation between the shearing depth of the plate and the target shearing depth, the central controller can adopt different strategies, such as secondary shearing or directly marking as unqualified to stop further processing; at the same time, the central controller can also automatically adjust the initial distance between the cutter discs based on the tool wear data to compensate for the shearing depth error caused by wear. This not only improves product quality, but also extends the service life of the upper and lower cutter disc assemblies and reduces maintenance costs.

[0028] Specifically, the disc shearing machine also includes a human-computer interaction screen, which is electrically connected to the central controller; the image collector captures the working process of the upper blade assembly and the lower blade assembly in real time; the human-computer interaction screen displays the real-time data obtained by the central controller, and controls the operation and adjustment parameters of the central controller according to the operation of the staff; and / or, the central controller has a data storage function, which records the shearing process of each plate to be processed by recording the data collected by the sensor group and the image collector.

[0029] The setting of the human-computer interaction screen enables the staff to monitor the cutting process and data in real time to make necessary parameter adjustments; the image acquisition device realizes the visualization of the cutting process, improves the transparency of the cutting work, and facilitates the staff to promptly discover and solve potential problems, such as tool abnormalities or plate conveying abnormalities, thereby enhancing the working stability and safety of the disc shearing machine and reducing downtime caused by accidents.

[0030] Optionally, the image collector collects image information of the upper cutter disc assembly and the image information of the lower cutter disc assembly to analyze and obtain wear data of the upper cutter disc assembly and the wear data of the lower cutter disc assembly, which is the third data; the sensor group detects the upper cutter disc assembly and the lower cutter disc assembly to obtain wear data of the upper cutter disc assembly and the wear data of the lower cutter disc assembly, which is the fourth data; the central controller analyzes and processes the third data and the fourth data to obtain actual wear data of the upper cutter disc assembly and the lower cutter disc assembly. When the actual wear data exceeds the allowable wear range, the central controller controls the drive assembly to stop working and reminds the staff to replace the upper cutter disc assembly and / or the lower cutter disc assembly; and / or, the material information of the plate to be processed is input into the central controller, and the central controller adjusts the initial distance between the upper cutter disc assembly and the lower cutter disc assembly and the rotation speed of the upper cutter disc assembly and the lower cutter disc assembly according to the material information.

[0031] Through dual monitoring of image information and sensor data, the central controller can more accurately evaluate tool wear and automatically remind users to replace tools, thus avoiding a decrease in cutting quality due to excessive tool wear. At the same time, this setting enables the central controller to adjust the initial distance and rotation speed between the cutter discs according to the material of the plate. This enables the machine to adapt to plates of different materials, improve its working flexibility and processing range, and ensure the cutting quality of plates of different materials.

[0032] Optionally, when the difference between the data collected by the sensor group and the same data collected by the image collector is within a set error range, the central controller performs weighted averaging processing on the same data collected by both; the weighted averaging processing process includes: the data collected by the sensor group is X, and the same data collected by the image collector is Y, and a first weighting coefficient A is obtained according to the manual setting and / or the data collection accuracy of the sensor group; a second weighting coefficient B is obtained according to the manual setting and / or the data collection accuracy of the image collector, the central controller calculates D=AX+BY, and then calculates D / (A+B) to obtain the final data of the same data, and the central controller adjusts the operation of the drive component, the transmission component and the adjustment component accordingly according to the final data; and / or, when the difference between the data collected by the sensor group and the same data collected by the image collector exceeds the set error range, the central controller sends an alarm message to remind the staff to make manual judgments and / or manually control the operation of the drive component, the transmission component and the adjustment component.

[0033] The weighted average processing of the sensor group and image acquisition data improves the accuracy and reliability of the data; when the data difference exceeds the set error range, the system issues an alarm message, prompting the staff to intervene manually, ensuring the safe operation of the disc shearing machine under special circumstances and avoiding production accidents caused by data errors.

[0034] Optionally, the sensor group includes an ultrasonic thickness sensor, a laser edge position sensor and an eddy current tool wear sensor; the ultrasonic thickness sensor is used to detect the thickness of the plate to be processed and / or the shear depth of the plate to be processed; the laser edge position sensor is used to detect the edge position of the plate to be processed; the eddy current tool wear sensor is used to detect the degree of wear of the upper cutter disc assembly and the degree of wear of the lower cutter disc assembly; and / or, the central controller uses a fuzzy logic algorithm to compare and process the data collected by the sensor group with the same data collected by the image collector, and calculates corresponding adjustment parameters to adjust the operation of the drive assembly, transmission assembly and adjustment assembly accordingly.

[0035] By setting the detailed composition of the sensor group and adopting the fuzzy logic algorithm in the central controller, the intelligent level of data processing is improved, and data can be compared and processed more accurately, and adjustment parameters can be calculated. The application of the fuzzy logic algorithm enables the central controller to adaptively adjust parameters according to different detection requirements and environmental changes, further improving the shearing accuracy and efficiency.

[0036] Specifically, the detection component also includes a material detector, which obtains material information by detecting the material of the plate to be processed, and the detection component adjusts the initial distance between the upper knife disc assembly and the lower knife disc assembly, and the rotation speed of the upper knife disc assembly and the lower knife disc assembly according to the material information; and / or, the disc shearing machine also includes a feeding assembly, which is used to transport the plate to be processed to a designated shearing position; and / or, the disc shearing machine also includes a box assembly, which is arranged on the frame assembly and covers the outside of the upper knife disc assembly and the lower knife disc assembly, so as to separate the upper knife disc assembly and the lower knife disc assembly from the outside.

[0037] The addition of the material detector enables the central controller to automatically adjust the blade parameters according to the material of the plate, which not only improves the shearing quality and efficiency, but also enhances the machine's adaptability to handle plates of different materials. The setting of the feeding component and the box component optimizes the plate conveying process and the machine's closedness, improves production safety, and reduces the interference of the external environment on the shearing production process.

[0038] like Figure 1As shown, the present invention also provides a shearing quality detection method, which is used for the above-mentioned disc shearing machine, and the shearing quality detection method includes the following steps: detecting the thickness of the plate to be processed, the edge position of the plate to be processed, the wear degree of the upper cutter disc assembly, the wear degree of the lower cutter disc assembly and the actual shearing depth of the plate to be processed; comparing the actual shearing depth of the plate to be processed with the target shearing depth; when the depth difference between the actual shearing depth of the plate to be processed and the target shearing depth exceeds the allowable error range, and the actual shearing depth of the plate to be processed is less than the target shearing depth, according to the depth difference, treating The processed plate is sheared twice according to the depth difference; when the depth difference between the actual shearing depth of the plate to be processed and the target shearing depth exceeds the allowable error range, and the actual shearing depth of the plate to be processed is greater than the target shearing depth, the plate to be processed is deemed to be unqualified; when the depth difference between the actual shearing depth of the plate to be processed and the target shearing depth exceeds the set value, the initial distance between the upper and lower cutter disc assemblies is adjusted accordingly based on the depth difference, combined with the degree of wear of the upper and lower cutter disc assemblies, to compensate for the shearing depth error caused by the wear of the upper and lower cutter disc assemblies.

[0039] The shearing quality detection method proposed in the present invention is a comprehensive application based on the above-mentioned structure and control strategy, which aims to achieve precise control of the shearing depth of the plate; through real-time detection and adaptive adjustment, this method can effectively deal with various problems that may be encountered in the plate shearing process (for example: inconsistent shearing depth, uneven plate edges or tool wear, etc.), ensure the shearing quality, reduce the need for subsequent quality inspection steps, and thus significantly improve production efficiency and economic benefits.

[0040] In a specific embodiment of the present invention, the shear quality detection method proposed in the present invention also includes the following steps: S1, real-time acquisition of a cross-sectional image of the plate after disc shearing; S2, through an image collector and a central controller, using a grayscale morphological algorithm and an edge detection algorithm to extract two boundary lines in the cross-sectional image and a separation line between the cut layer and the tear layer, and then obtain the width of the cut layer corresponding to the cross-sectional image, and use the width of the cut layer as the real-time shear depth; S3, compare the obtained real-time shear depth with the target shear depth. If the difference between the two is greater than a preset maximum threshold, the obtained real-time shear depth is sent to the staff, so that the staff can manually adjust various parameters according to the real-time shear depth.

[0041] The specific working process and principle of an embodiment of the present invention are now described in detail as follows:

[0042] The disc shearing machine includes a frame assembly, left and right disc box assemblies, a transmission assembly, and an adjustment assembly for adjusting the knife shaft and the knife disc and the opening degree; a rotatable upper knife disc assembly and a lower knife disc assembly are arranged on the frame assembly to perform a shearing operation on the plate together; a feeding assembly is installed at the front end of the frame assembly, and can stably convey the plate to between the upper knife disc assembly and the lower knife disc assembly for shearing;

[0043] Before starting the disc shearing machine, input parameter information such as the material, thickness, target shearing depth and width of the plate to be processed, and the central controller initializes the operating parameters of the equipment according to these input parameters, including the initial distance between the upper and lower blade disc assemblies, the speed of the motor in the driving assembly, etc.; after starting the disc shearing machine, the plate begins to enter the disc shearing machine, and the sensor group and image collector in the detection assembly start working respectively, collecting data such as the thickness, edge position, wear degree of the upper and lower blade disc assemblies, and shearing depth of the plate in real time, and transmits these data to the data processing and analysis unit of the central controller;

[0044] When it is detected that the sheared sheet has a shear depth deviation, the central controller calculates the corresponding control adjustment parameters according to the pre-input intelligent algorithm, and then adjusts the drive component, transmission component and adjustment component accordingly to adjust the processing parameters of the disc shearing machine for the sheet accordingly;

[0045] During the entire shearing process, the human-machine interactive interface displayed on the human-machine interactive screen displays various data, the operating status of each component, and the adjustment process and results of the central controller in real time, so that the staff can view them at any time; if there is equipment failure or quality problem, the human-machine interactive interface will send out an alarm signal in time, and the staff can take corresponding measures according to the alarm information (such as stopping for inspection, replacing tools, etc.); after the shearing is completed, the central controller automatically records various parameters and data of this processing process to form a processing log, which can be used for subsequent quality analysis, equipment maintenance and process optimization reference;
