Description

Technical Field

[0001] This invention relates to the field of wire drawing technology, and in particular to a quick-change method and system for wire drawing dies. Background Technology

[0002] Wire drawing dies are an important piece of equipment widely used in the copper wire processing industry. They are used to stretch copper wires through the die aperture to obtain copper wires of the required specifications and surface quality. The accurate installation and replacement of wire drawing dies play a decisive role in the operating efficiency of wire drawing equipment and the quality of finished products. Especially in industrial production that requires multiple wire drawing passes, alternating operations of different specifications of wires, or batch processing, the frequency of die disassembly and assembly is high, which places dual requirements on the efficiency and accuracy of the replacement method.

[0003] Existing methods for changing wire drawing dies are mostly manual, requiring operators to remove the dies after they have been used and then assemble them according to the requirements of the next process. This traditional method has drawbacks such as cumbersome operation steps, low efficiency, and strong reliance on operator experience. In multi-task or continuous wire drawing production, it is difficult to meet the requirements of efficient switching and precise assembly. In particular, it may lead to longer production cycles and increased equipment downtime, further affecting overall capacity and economic benefits.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the general background of this disclosure and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention

[0005] This invention provides a quick-change method and system for wire drawing dies, which can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] A quick-change method for wire drawing dies, the method comprising:

[0008] Obtain wire drawing operation information, including a first wire drawing task and a second wire drawing task, wherein the first wire drawing task is a wire drawing operation to be executed, and the first wire drawing task and the second wire drawing task are executed sequentially;

[0009] A slot mold assembly is established, which is composed of multiple wire drawing molds, and the wire drawing molds are assembled sequentially according to the processing order of the wire drawing operation.

[0010] The wire drawing operation is performed according to the assembled slot mold assembly, and the wire drawing mold that has finished execution is pre-replaced and assembled according to the second wire drawing task.

[0011] Furthermore, assembling the wire drawing die in sequence according to the processing order of the wire drawing operation includes:

[0012] A first costume change sequence and a second costume change sequence are established according to the first and second costume change tasks, respectively.

[0013] The first wire drawing task and the second wire drawing task are set according to the slot mold group, and the initial slot position is set according to the first changing sequence;

[0014] The operation time is assigned to each drawing die in the initial slot according to the first drawing task.

[0015] Furthermore, the pre-replacement and assembly of the wire drawing die after its execution is completed according to the second wire drawing task includes:

[0016] Starting with the wire drawing die in the initial slot, when the wire drawing die in the first changing sequence is completed, the wire drawing die is replaced sequentially according to the second changing sequence, with an additional operation time.

[0017] When the first wire drawing task reaches the last wire drawing die, the wire drawing die corresponding to the second garment changing sequence is obtained, and it is determined whether it is the last execution die of the garment changing sequence;

[0018] If not, when performing the wire drawing operation of the second changing sequence, continue to assemble the slot mold group for the second wire drawing task according to the second changing sequence.

[0019] Furthermore, after all the wire drawing dies corresponding to the first changing sequence have completed the wire drawing operation, all the wire drawing dies corresponding to the second changing sequence in the slot die group are sequentially replaced to the first changing sequence, and the subsequent wire drawing task is set as the second wire drawing task.

[0020] Furthermore, a mold database is established for the slot mold group to use, including:

[0021] Traverse the mold library to generate a unique identifier for each wire drawing mold, and make it correspond one-to-one with each wire drawing mold. The mold library is the storage space for the wire drawing molds.

[0022] Record the location information and historical usage information of the wire drawing die in the die library, and generate a dynamic identifier for each wire drawing die;

[0023] The unique identifier is used to authenticate the wire drawing die, and the dynamic identifier is used to trace historical data and retrieve the wire drawing die.

[0024] Furthermore, the method also includes generating a temporary mark on the pre-assembled wire drawing die assembly for positioning and assembly of the slot die assembly, including:

[0025] The pre-assembled wire drawing die is obtained according to the wire drawing task, and the location information of the die library is obtained through the dynamic identifier;

[0026] A temporary identifier is generated for the obtained wire drawing die, and the slot position of the slot die group is determined according to the processing operation sequence;

[0027] The slot is used to position and assemble the wire drawing die according to the temporary mark, ensuring the uniqueness of the slot die assembly position for each wire drawing die.

[0028] Furthermore, it also includes: loading the dynamic identifier, selecting the wire drawing die based on the historical usage information, and determining the retrieval path based on the location information.

[0029] Furthermore, when the wire drawing die is pre-replaced, the wire drawing die that has finished execution is recalled back to the die library, and the corresponding location information and historical usage information are updated to generate a new dynamic identifier overlay.

[0030] Furthermore, a data analysis model is established to perform big data analysis on the historical usage information to obtain the wear information of the wire drawing die parts and assess the remaining service life.

[0031] A quick-change system for wire drawing dies, the system comprising:

[0032] The job acquisition module acquires wire drawing job information, including a first wire drawing task and a second wire drawing task, wherein the first wire drawing task is the wire drawing job to be executed, and the first wire drawing task and the second wire drawing task are executed sequentially.

[0033] The card slot assembly module establishes a card slot mold group, which is composed of multiple wire drawing molds assembled in sequence according to the processing order of the wire drawing operation.

[0034] The mold changing module performs wire drawing operations based on the assembled slot mold group, and pre-replaces and assembles the wire drawing mold that has finished execution according to the second wire drawing task.

[0035] The technical solution of this invention can achieve the following technical effects:

[0036] To address the practical needs of multi-stage, high-frequency mold changes in copper wire production, a standardized, automated, and efficient mold change process was achieved by establishing a slot mold group and assembling it in an orderly manner according to the wire drawing task sequence. This simplifies operation steps, reduces human error, shortens mold change time, lowers equipment downtime, and improves the overall operating efficiency and capacity of the copper wire production line. At the same time, through systematic mold management and changeover scheduling, the quality of finished copper wire and the continuous stability of the production process are further guaranteed, effectively meeting the requirements of modern copper wire industry for efficient, precise, and flexible production.

[0037] The above description is only an overview of the technical solution of this application. In order to better understand the technical means of this application and to implement it in accordance with the contents of the specification, and to make the above and other objects, features and advantages of this application more obvious and understandable, the following are specific embodiments of this application.

[0043] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0044] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0045] Example 1;

[0046] like Figure 1 As shown, this application provides a quick-change method for wire drawing dies, the method comprising:

[0047] S10: Obtain wire drawing operation information, including a first wire drawing task and a second wire drawing task, wherein the first wire drawing task is the wire drawing operation to be executed, and the first wire drawing task and the second wire drawing task are executed sequentially;

[0048] S20: Establish a slot mold group, which is composed of multiple wire drawing molds assembled in sequence according to the processing order of the wire drawing operation;

[0049] S30: Perform wire drawing operation according to the assembled slot mold group, and pre-replace and assemble the wire drawing mold that has finished execution according to the second wire drawing task.

[0050] Specifically, the system first acquires operational information, including the first and second wire drawing tasks, corresponding to the specifications required for the current copper wire drawing and the subsequent production tasks to be switched over. Then, by establishing a slot mold group, multiple wire drawing dies for copper wire processing are assembled into multiple slots according to a preset sequence based on actual process requirements. A corresponding replacement sequence is then established for the first and second wire drawing tasks. During actual production, if the first and second wire drawing processes need to be completed sequentially, the operator can pre-position the required dies in the slot mold group to achieve continuous drawing operations. As the first wire drawing task is completed, the system can automatically or pre-emptively replace the completed dies with the dies for the subsequent tasks according to the requirements of the second wire drawing task. The required molds ensure seamless connection and efficient switching in copper wire drawing production. It's important to note that the first and second drawing tasks are respectively assembled into the slot mold group, rather than the second drawing task being connected after the first. Specifically, the slot mold group consists of several slots, each equipped with a drawing mold. On a unit basis, after the first drawing task's corresponding drawing operation is completed, the slot immediately assembles the drawing mold corresponding to the processing sequence of the second drawing task. This not only significantly shortens the mold changeover time of the copper wire drawing production line but also enables automatic and flexible switching between multiple tasks and sequences, reducing manual intervention, improving production efficiency, and further meeting the high-efficiency and high-quality processing needs of modern copper products.

[0051] The technical solution of this invention addresses the practical needs of multi-stage, high-frequency mold changes in copper wire production. By establishing a slot mold group and assembling it in an orderly manner according to the wire drawing task sequence, the mold change process is standardized, automated, and efficient. This simplifies operation steps, reduces human error, shortens mold change time, lowers equipment downtime, and improves the overall operating efficiency and capacity of the copper wire production line. At the same time, through systematic mold management and changeover scheduling, the quality of finished copper wire and the continuous stability of the production process are further guaranteed, effectively meeting the requirements of modern copper wire industry for efficient, precise, and flexible production.

[0052] Furthermore, assembling the wire drawing die in sequence according to the processing order of the wire drawing operation includes:

[0053] Establish a first costume change sequence and a second costume change sequence according to the first and second filament drawing tasks respectively;

[0054] The first and second wire drawing tasks are set with corresponding slot mold groups, and the initial slot position is set according to the first changing sequence;

[0055] The operation time is assigned to each drawing die in the initial slot according to the first drawing task.

[0056] As a preferred embodiment of the above, in practical applications, the system first generates corresponding first and second assembly sequences based on the first drawing task to be implemented and the predetermined second drawing task. According to the process sequence, the drawing dies required for each are assembled into the corresponding slots of the slot die group in an orderly manner according to the first assembly sequence, while the second assembly sequence is in a pre-assembled state. During the production process, the system also adds an operation time mark to each slot die to realize full monitoring of the die usage status and subsequent maintenance. After the first task is completed, the spare die can be quickly transferred into the main slot to smoothly connect to the second drawing task without manual disassembly and assembly, realizing continuous and efficient production. This method not only optimizes the overall process of drawing operations, but also improves the accuracy of operations and the level of automation, providing an efficient solution for multi-task and multi-specification copper wire drawing production.

[0057] Furthermore, the pre-replacement and assembly of the drawing die after the second drawing task has ended includes:

[0058] Starting with the wire drawing die in the initial slot, when the wire drawing die in the first changing sequence is completed, the wire drawing die is replaced in the corresponding order according to the second changing sequence, with the operation time attached.

[0059] When the first wire drawing task reaches the last wire drawing die, obtain the wire drawing die corresponding to the second garment changing sequence, and determine whether it is the last die to be executed in the garment changing sequence;

[0060] If not, when performing the wire drawing operation of the second changing sequence, continue to assemble the slot mold group for the second wire drawing task according to the second changing sequence.

[0061] In this embodiment, the wire drawing production system first automatically generates a first changing sequence and a second changing sequence based on the process plan. The changing sequence is a list of die usage order sorted and output by the system for different wire drawing task requirements. Each changing sequence corresponds to the required wire drawing die model, quantity, and arrangement order, and corresponds one-to-one with the slot number of the slot die group. In the actual production process, the wire drawing dies of the first changing sequence are pre-assembled into the initial slots of the slot die group. As the first wire drawing task proceeds, the system monitors the operating status of each slot die in real time. When it detects that a die has completed the first changing sequence... After the task in the sequence, the system automatically performs pre-replacement of the slot according to the second changing sequence: that is, unload the completed mold and assemble the corresponding wire drawing mold in the second changing sequence. The newly assembled mold is tagged with a work time, so that the wire drawing mold required for the corresponding slot in the second changing sequence can be obtained in advance within the work time. This facilitates the pre-obtaining of the wire drawing mold required for the corresponding slot in the second changing sequence. This replacement operation is performed sequentially until all molds in the first changing sequence have completed their processes. When the first wire drawing task reaches the last wire drawing mold, such as Figure 2 As shown, the system obtains the mold corresponding to the second replacement sequence and determines whether the current replacement has covered the last mold of the second replacement sequence. If the replacement has not been completed, the system continues to assemble and replace the remaining molds according to the second replacement sequence after the second wire drawing task is started, ensuring that the second task can be switched smoothly and operated continuously. It should be noted that when the system completes the assembly of the remaining slots of the second replacement sequence, it does not affect the subsequent wire drawing task from continuing to replace the current wire drawing task. That is, the two are replaced synchronously until the second replacement sequence is fully assembled.

[0062] Furthermore, after all the wire drawing dies corresponding to the first changing sequence have completed the wire drawing operation, all the wire drawing dies corresponding to the second changing sequence in the slot die group are replaced to the first changing sequence in turn, and the subsequent wire drawing task is set as the second wire drawing task.

[0063] In this embodiment, the first and second replacement sequences are relative. The first replacement sequence represents the wire drawing task to be executed, while the second replacement sequence identifies the preparatory wire drawing task, which is adjacent to the first wire drawing task. When the first wire drawing task is completed, according to the implementation method of the above embodiment, the slot mold group has already assembled the corresponding wire drawing molds according to the second replacement sequence. Then, the preparation of the wire drawing molds required for the next wire drawing task continues in this manner. In order to facilitate the assembly of the slot mold group, the first replacement sequence always corresponds to the wire drawing task to be executed, while the second replacement sequence always corresponds to the task adjacent to the first replacement sequence. When a change occurs, the name and the actual task it carries also need to be changed accordingly.

[0064] Furthermore, such as Figure 3 As shown, a mold database is established for the slot mold group to use, including:

[0065] Traverse the mold library, generate a unique identifier for each wire drawing mold, and ensure that each wire drawing mold corresponds to a unique identifier. The mold library is the storage space for wire drawing molds.

[0066] Record the location and historical usage information of wire drawing dies in the die library, and generate dynamic identifiers for each wire drawing die;

[0067] The system uses a unique identifier to authenticate the wire drawing die, and a dynamic identifier to trace historical data and retrieve the wire drawing die.

[0068] Based on the above embodiments, the system first performs a comprehensive registration of all wire drawing dies stored in the die library, i.e., the wire drawing die storage space. The system can use laser-engraved QR codes, RFID electronic tags, barcodes, etc., to assign a globally unique identifier to each wire drawing die, and bind this identifier to the die's physical information (such as diameter, material, manufacturer, and storage time). This unique identifier remains unchanged throughout the die's lifecycle and is used for identity authentication and unique traceability. Each wire drawing die has a physical storage location in the die library. The system records the die's current location in real time using location coding or location information sensors such as RFID positioning and NFC location markers. The database automatically updates the die's storage location information synchronously, ensuring that the automated assembly system can quickly and accurately locate the target die. To achieve comprehensive traceability of the die's usage history, the system updates the information every time a wire drawing die is retrieved and assembled. When using and returning the mold, a set of dynamic identifiers is automatically generated, and relevant operational information of the mold is recorded, including retrieval time, wire drawing task number, start and end time of operation, actual copper wire specifications processed, cumulative wire drawing length, equipment number, etc. Each operation forms a complete historical record chain in the database, which is convenient for later traceability, data analysis and maintenance management. The dynamic identifier can be implemented in various forms such as soft tags, electronic records, and data table fields. When the slot mold group needs to call the wire drawing mold, it first retrieves the unique identifier of the target mold through the database to complete the identity authentication. Then, the system traces its historical data such as the most recent usage status, cumulative operation time, maintenance information, etc., based on the dynamic identifier to determine the suitability and health status of the mold, and retrieves the physical storage location information to guide the automatic assembly system or operator to take the mold out of the mold library and install it into the designated slot.

[0069] Furthermore, the method also includes generating temporary markings for the pre-assembled wire drawing die assembly, for positioning and assembly of the slot die assembly, including:

[0070] The pre-assembled wire drawing die is obtained based on the wire drawing task, and the location information of the die library is obtained through dynamic identification.

[0071] A temporary identifier is generated for the obtained wire drawing die, and the slot position of the slot die group is determined according to the processing operation sequence;

[0072] The slot is used to position and assemble the wire drawing die according to the temporary markings, ensuring the uniqueness of the slot die assembly position for each wire drawing die.

[0073] In this embodiment, the wire drawing production management system retrieves a list of wire drawing dies to be pre-assembled from the die database based on the current wire drawing task requirements. By reading the dynamic identifier of each wire drawing die, the system automatically retrieves the physical storage location information of the die, enabling the automated logistics device to efficiently retrieve and centrally pre-assemble the required dies. After completing the pre-assembly of the die group, the system generates a unique temporary identifier for that batch of wire drawing die groups. The temporary identifier can be generated using a one-time QR code label, NFC / RFID electronic code, or dynamic digital string. This temporary identifier is bound one-to-one with the processing sequence of all wire drawing dies in this batch of die groups within that batch of processes. The system then automatically determines each slot of the card slot mold group according to the process requirements and operation sequence of this wire drawing task, and associates it with the temporary identifier of the wire drawing mold group. During the actual assembly process, each slot of the card slot mold group is equipped with an identification device that can automatically read the temporary identifier on the assembly mold group. By checking the temporary identifier and assembly sequence, the system ensures that each wire drawing mold can only be uniquely located and assembled into the designated slot, avoiding errors that are prone to occur in manual assembly, such as misassembly, omission, and mixed assembly. After the assembly is completed, the database updates the uniqueness mapping of the slot position and the temporary identifier in real time, ensuring the automation, continuity and traceability of the subsequent wire drawing production process.

[0074] Furthermore, the method also includes: loading dynamic identifiers, selecting wire drawing dies based on historical usage information, and determining the retrieval path based on location information.

[0075] In a preferred embodiment, the system first loads the dynamic identifiers of all wire drawing dies from the die database. Upon receiving a new wire drawing production task, the system automatically traverses the die library, filters and evaluates the required specifications of wire drawing dies, and prioritizes dies with good health, complete maintenance records, and long remaining service life. The system automatically retrieves the dynamic identifiers of all target dies, obtains the historical cumulative usage information and current physical location of each die in real time, and inputs the selected die location information into the scheduling module to automatically plan the die retrieval path. For example, it prioritizes the centralized retrieval of dies from the same shelf, adjacent compartments, or the same area, or generates the shortest retrieval route for the automated logistics robot, thereby saving material handling time, reducing the distance of manual or equipment movement, and improving die adjustment efficiency. The scheduling system distributes the final retrieval instruction to the automated logistics unit or robotic arm, accurately retrieves the selected die to the pre-assembly area according to the planned path, and performs subsequent unique positioning assembly with the slot die group.

[0076] Furthermore, when the wire drawing die is pre-replaced, the wire drawing die that has finished execution is recalled back to the die library, and the corresponding location information and historical usage information are updated to generate a new dynamic identifier overlay.

[0077] In this embodiment, when the wire drawing production line needs to pre-install a new die, the wire drawing die that has completed the current wire drawing task, i.e., the wire drawing die that has finished its execution, will be unloaded from the die slot assembly. The system uses automated logistics equipment to return the die to an idle position in the die library. During the return process, the system first identifies the die by scanning the unique identifier on the die and automatically cancels its assembly status on the production line in the die management database. Simultaneously, the system updates the current storage location of the die in real time. More importantly, the system automatically adds all historical information of the die for this operation, such as the current wire drawing task number, operation start and end time, wire drawing process parameters, actual cumulative wire drawing length, maintenance and abnormal status, etc., to the historical record table of the die's database. Subsequently, the system generates a new dynamic identifier for the die. This dynamic identifier completely covers and replaces the old dynamic identifier of the die for the previous task, ensuring the integrity and uniqueness of the data traceability chain.

[0078] Furthermore, such as Figure 4 As shown, a data analysis model is established to perform big data analysis on historical usage information, obtain information on the wear and tear of wire drawing dies, and assess the remaining service life.

[0079] Building upon the aforementioned embodiments, the system automatically collects historical usage information for each wire drawing die through a full lifecycle management platform. This information includes, but is not limited to: cumulative wire drawing length, actual operating time, involved process parameters (drawing force, wire diameter, processing speed), number of die changes, maintenance and repair records, fault and anomaly information, and ambient temperature and humidity. All raw data is cleaned and standardized before being stored in a structured data table. Based on the large amount of historical data collected, the system incorporates machine learning techniques, such as regression analysis, cluster analysis, and time series analysis, to analyze the core factors affecting the lifespan of wire drawing dies (such as material properties, operating intensity, temperature load, and typical damage modes). Feature extraction and modeling can also be divided into feedback of historical mold execution time and copper wire forming quality information. Combining historical loss data with the current process environment, the model is based on the remaining life prediction algorithm to evaluate the remaining cycle or total drawing meters of each drawing die in real time, and provides suggestions for maintenance, scrapping or continued use, as well as the evaluation of parameters such as life threshold, risk level, and maintenance window. The prediction results are automatically pushed to the production management, equipment maintenance and scheduling system. High loss and critical life molds are marked for priority maintenance or replacement, and healthy molds are prioritized for production, optimizing production safety and efficiency. Managers can make decisions on mold batch management, advance procurement and preventive maintenance based on model reports.
