Description

Technical Field

[0001] This invention relates to the field of mechanical manufacturing technology, specifically to a method and system for automatically selecting retaining rings and designing spring machine molds. Background Technology

[0002] In the production of retaining rings (such as snap rings), it is necessary to select a suitable spring machine and matching mold based on their specific specifications (such as whether for holes or shafts, outer diameter, wire diameter / width, thickness, and cut type). Traditionally, this relies on experienced engineers manually consulting tables, calculating, and judging, a cumbersome and error-prone process. Especially when dealing with non-standard products or new models, a significant amount of time is often spent on mold design. Current technology lacks a systematic solution that integrates parameter input, intelligent calculation, feasibility analysis, and automatic mold matching / design, resulting in long production preparation cycles and low efficiency. Summary of the Invention

[0003] This invention provides a method and system for automatically selecting and designing spring machine molds for retaining rings, in order to solve the problem that the process of selecting or designing modules for non-standard products or new models of retaining rings is complex and time-consuming.

[0004] In a first aspect, the present invention provides a method for automatically selecting retaining rings and designing spring machine molds, the method comprising: Obtain the basic parameters of the retaining ring to be processed, and determine the final model that meets the requirements of each processing stage based on the basic parameters. The basic parameters include: thickness, width, outer diameter, cut type, application, and offset status. Calculate the width-to-thickness ratio based on the width and thickness of the retaining ring to be processed, and determine whether it meets the requirements for fan-shaped processing based on the width or width-to-thickness ratio. If the requirements for fan-shaped processing are met, the inner arc angle of the fan-shaped cut is determined according to the basic parameters of the retaining ring to be processed and the final machine model. If the requirements for fan-shaped processing are not met, the punching angle is determined according to the cut type and application. Based on the final machine model, the inner arc angle of the fan-shaped cut, the punching angle, and the basic parameters, select or design a mold for the retaining ring to be processed.

[0005] This invention provides a method for automatically selecting and designing molds for retaining ring spring machines. By acquiring the basic parameters of the retaining ring, it automatically determines the final machine model that meets the requirements of each processing stage. Then, based on the width-to-thickness ratio, it judges whether the requirements for fan-shaped processing are met, and then specifically determines the inner arc angle or punching angle of the fan-shaped cut. Combining the final machine model and basic parameters, it completes the automatic selection or design of the mold, realizing the full automation and intelligence of the selection and design process of retaining ring spring machine molds. This avoids the errors of manual calculation and experience judgment, improves the efficiency and accuracy of mold design, and accurately matches processing parameters according to the specifications and process requirements of the retaining ring, effectively ensuring the processing quality and production stability of the retaining ring, reducing the dependence on the professional skills of operators, and adapting to the batch production needs of retaining rings of different specifications.

[0006] In one optional implementation, determining the final machine model that meets the requirements of each processing stage based on basic parameters includes: Calculate the cross-sectional area based on the width and thickness of the retaining ring to be processed, and select the appropriate cross-sectional area measuring machine model based on the cross-sectional area. Select the machine model based on the outer diameter; Calculate the blanking force based on the cut type, width, and thickness, and determine the blanking machine type based on the blanking force; Select the machine model that simultaneously meets the requirements for cross-sectional area, outer diameter, and punching force from the cross-sectional area, outer diameter, and punching force models as the final machine model.

[0007] This invention provides a method for automatically selecting and designing spring machine molds for retaining rings. By screening corresponding machine models based on three core processing constraints—cross-sectional area, outer diameter, and punching force—and then selecting the final machine model that simultaneously meets all constraints from the three candidate models, it achieves systematic coverage and precise matching of the process requirements for all stages of retaining ring processing. This avoids insufficient processing capacity or waste of equipment resources that may result from selecting a single parameter, ensuring that the selected machine model can meet both the structural dimensional requirements of retaining ring forming and the load requirements of the punching process. This effectively improves the scientificity and reliability of machine model selection and reduces production risks and cost losses caused by selection errors.

[0008] In one optional implementation, determining whether the fan-shaped processing requirements are met based on the width or width-to-thickness ratio includes: If the width is less than the width threshold, or the width-to-thickness ratio is less than the width-to-thickness ratio threshold, then the retaining ring to be processed is determined to not meet the requirements for fan-shaped processing. If the width is not less than the width threshold and the width-to-thickness ratio is not less than the width-to-thickness ratio threshold, then the retaining ring to be processed is determined to meet the requirements for fan-shaped processing.

[0009] In one optional implementation, the inner arc angle of the sector-shaped cut is determined based on the basic parameters of the retaining ring to be processed and the final machine model, including: Based on the purpose, offset status, final machine model, outer diameter, and width of the retaining ring to be processed, a multi-layer nested conditional judgment logic is used to query the logic table to determine the inner arc angle of the corresponding sector cut.

[0010] This invention provides a method for automatically selecting and designing spring machine molds for retaining rings. By setting width and width-to-thickness ratio thresholds as entry conditions for fan-shaped processing, it achieves automated and standardized judgment on whether the retaining ring is suitable for fan-shaped cuts, avoiding the subjectivity and error of manual experience judgment and ensuring process feasibility. Based on multi-dimensional parameters such as application, offset state, final machine model, outer diameter, and width, a multi-layer nested condition judgment logic is used to query a preset logic table to determine the inner arc angle of the fan-shaped cut. This achieves accurate and efficient matching of arc angle parameters, which not only meets the needs of different working conditions and structures, but also ensures the consistency and standardization of parameter design, effectively improving the accuracy and efficiency of fan-shaped cut mold design.

[0011] In one alternative implementation, determining the punching angle based on the cut type includes: If the cut type is beveled, the punching angle is determined according to the application, including: If the application is for a double beveled shaft, the blanking angle is 60 degrees; If the application is for a double beveled hole, the punching angle is 150 degrees.

[0012] In one optional implementation, a mold is selected or designed for the retaining ring to be processed based on the final machine model, the inner arc angle of the fan-shaped cut, the punching angle, and basic parameters, including: If the cut type is natural cut, the built-in rule table is queried based on the final machine model, application, offset status, width, and thickness to generate mold parameters; You can query the mold database or design a new mold based on the mold parameters.

[0013] This invention provides a method for automatically selecting and designing molds for retaining rings. By directly binding the cut type and application to a fixed punching angle, it achieves standardized and automated configuration of punching process parameters, avoiding manual calculations and experience-based biases, and ensuring the assembly performance and processing consistency of retaining rings. Simultaneously, for natural cut types, it generates mold parameters by querying a built-in rule table based on multi-dimensional parameters such as the final machine model, application, and offset status. Mold selection is then completed through database queries or new design. This achieves full-process automation of mold design for different cut types and accurately matches production conditions and structural requirements, significantly improving mold design efficiency and accuracy, reducing reliance on operator skills, and providing reliable support for stable mass production of retaining rings.

[0014] Secondly, the present invention provides a system for automatically selecting retaining rings and designing spring machine molds, the system comprising: The machine selection module is used to obtain the basic parameters of the retaining ring to be processed, and to determine the final machine model that meets the requirements of each processing stage based on the basic parameters. The basic parameters include: thickness, width, outer diameter, cut type, application, and offset status. The processing type determination module is used to calculate the width-to-thickness ratio based on the width and thickness of the retaining ring to be processed, and to determine whether it meets the requirements for fan-shaped processing based on the width or width-to-thickness ratio. The mold parameter determination module is used to determine the inner arc angle of the fan-shaped cut according to the basic parameters of the retaining ring to be processed and the final machine model if the fan-shaped processing requirements are met; if the fan-shaped processing requirements are not met, the punching angle is determined according to the cut type and application. The mold selection and design module is used to select or design molds for the retaining ring to be processed based on the final machine model, the inner arc angle of the fan-shaped cut, the punching angle, and basic parameters.

[0015] Thirdly, the present invention provides an electronic device, comprising: a memory and a processor, the memory and the processor being communicatively connected to each other, the memory storing computer instructions, and the processor executing the computer instructions to perform the method described in the first aspect or any corresponding embodiment thereof.

[0016] Fourthly, the present invention provides a computer-readable storage medium storing computer instructions for causing a computer to perform the method described in the first aspect or any corresponding embodiment thereof.

[0025] This invention provides a method for automatically selecting and designing spring machine molds for retaining rings. Based on the basic parameters of the retaining ring to be processed, the method automatically determines the spring machine model that meets the processing requirements and calculates the mold parameters to select or design the corresponding mold. This achieves the goal of adapting spring machines and molds to non-standard or new retaining rings, thus meeting the needs of mass production of retaining rings of different specifications.

[0026] According to an embodiment of the present invention, a method for automatically selecting retaining rings and designing spring machine molds is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0027] This embodiment provides a method for automatically selecting retaining rings and designing spring machine molds, which can be used in the aforementioned computer system. Figure 2 This is a flowchart of a method for automatically selecting retaining rings and designing spring machine molds according to an embodiment of the present invention, such as... Figure 2 As shown, the process includes the following steps: Step S201: Obtain the basic parameters of the retaining ring to be processed, and determine the final model that meets the requirements of each processing stage based on the basic parameters. The basic parameters include: thickness, width, outer diameter, cut type, application, and offset status.

[0028] Specifically, the basic parameters of the retaining ring to be processed can be obtained manually according to the requirements. The machine model determination module selects the final model of the spring machine that meets the processing requirements of each processing stage based on the basic parameters of the retaining ring to be processed. For example, the common models of spring machines include: 20 machine, 35 machine, 60 machine, 70 machine, etc. The larger the number, the larger the size of the spring machine that can be processed, the stronger the punching force it can withstand, and the wider the processing range. Smaller models have better structural rigidity, motion accuracy, and dimensional stability than larger models. Therefore, under the premise of meeting the processing requirements of the retaining ring to be processed, smaller models of spring machines should be selected as much as possible.

[0029] Step S202: Calculate the width-to-thickness ratio based on the width and thickness of the retaining ring to be processed, and determine whether it meets the requirements for fan-shaped processing based on the width or width-to-thickness ratio.

[0030] Specifically, based on the width W and thickness T of the retaining ring to be processed, the width-to-thickness ratio is calculated: width-to-thickness ratio = W / T. Based on the width and width-to-thickness ratio, it is determined whether a fan-shaped cut can be stamped. If a fan-shaped cut cannot be stamped, the user is prompted that it does not meet the requirements for fan-shaped processing.

[0031] Step S203: If the requirements for fan-shaped processing are met, the inner arc angle of the fan-shaped cut is determined according to the basic parameters of the retaining ring to be processed and the final machine model. If the requirements for fan-shaped processing are not met, the punching angle is determined according to the cut type and application.

[0032] Specifically, if the requirements for fan-shaped processing are met, the process directly enters the fan-shaped cutting branch. The inner arc angle of the fan-shaped cutting is determined based on the basic parameters of the retaining ring to be processed and the final machine model, without the need for additional judgment of the cutting type. If the requirements for fan-shaped processing are not met, the process enters the ordinary cutting branch, and the punching angle or die parameters are determined based on the cutting type and application.

[0033] In practical applications, the product design drawings are used to determine whether the product meets the requirements for fan-shaped processing. If the product design drawings indicate a fan-shaped product, the width or width-to-thickness ratio is used to determine if the product meets the requirements. If it does, the subsequent processing is carried out according to the fan-shaped processing technology. If it does not meet the requirements, it is further determined whether to change the cut type. If the product design drawings indicate a non-fan-shaped product, the punching angle is determined according to the cut type and application.

[0034] Step S204: Select or design a mold for the retaining ring to be processed based on the final machine model, the inner arc angle of the fan-shaped cut, the punching angle, and the basic parameters.

[0035] Specifically, the mold matching and design module queries the existing mold database based on the generated parameters (final model, inner arc angle of the fan-shaped cut, punching angle, and basic parameters). If a perfectly matching mold number is found, it is output directly; otherwise, all generated parameters are packaged as mold parameters to form a complete new mold design task book to guide the production of the new mold. This enables fully automated selection and design of retaining ring molds, significantly improving production efficiency and accuracy.

[0036] This embodiment provides a method for automatically selecting and designing retaining ring spring machine molds. By acquiring the basic parameters of the retaining ring, the method automatically determines the final machine model that meets the requirements of each processing stage. Then, based on the width-to-thickness ratio, it judges whether the requirements for fan-shaped processing are met. Subsequently, it determines the inner arc angle or punching angle of the fan-shaped cut. Combining the final machine model and basic parameters, the method completes the automatic selection or design of the mold, realizing the full automation and intelligence of the selection and design process of retaining ring spring machine molds. This avoids the errors of manual calculation and experience judgment, improves the efficiency and accuracy of mold design, and accurately matches the processing parameters according to the specifications and process requirements of the retaining ring, effectively ensuring the processing quality and production stability of the retaining ring, reducing the dependence on the professional skills of operators, and adapting to the batch production needs of retaining rings of different specifications.

[0037] This embodiment provides a method for automatically selecting retaining rings and designing spring machine molds, which can be used in the aforementioned computer system. Figure 3This is a flowchart of a method for automatically selecting retaining rings and designing spring machine molds according to an embodiment of the present invention, such as... Figure 3 As shown, the process includes the following steps: Step S301: Obtain the basic parameters of the retaining ring to be processed, and determine the final model that meets the requirements of each processing stage based on the basic parameters. The basic parameters include: thickness, width, outer diameter, cut type, application, and offset status.

[0038] Specifically, step S301 includes: Step S3011: Calculate the cross-sectional area based on the width and thickness of the retaining ring to be processed, and select the cross-sectional area machine model based on the cross-sectional area.

[0039] Specifically, the formula for calculating the cross-sectional area of ​​the retaining ring to be processed is: S = W × T, where S represents the cross-sectional area of ​​the retaining ring to be processed, W represents the width, and T represents the thickness. The corresponding cross-sectional area model is selected based on the different ranges the cross-sectional area falls into. For example, if the cross-sectional area ≤ 3.14, the corresponding cross-sectional area model is 20; if 3.14 < cross-sectional area ≤ 9.6, the corresponding cross-sectional area model is 35; if 9.6 < cross-sectional area ≤ 28.26, the corresponding cross-sectional area model is 60; and if the cross-sectional area is greater than 28.26, the corresponding cross-sectional area model is 70. This is just an example and is not a limitation.

[0040] Step S3012: Select the outer diameter model based on the outer diameter.

[0041] Specifically, different outer diameter sizes correspond to different outer diameter machine models. Therefore, select the appropriate outer diameter machine model based on the outer diameter of the retaining ring to be processed. For example, if the outer diameter is 36mm, within the range of 8mm-55mm, select model 20; if the outer diameter is 78mm, within the range of 55mm-95mm, select model 35; if the outer diameter is 210mm, within the range of 95mm-320mm, select model 60; and if the outer diameter is greater than 320mm, select model 70. This is just an example and is not a limitation.

[0042] Step S3013: Calculate the punching force according to the cut type, width, and thickness, and determine the punching force machine type based on the punching force.

[0043] Specifically, determine the coefficient according to the notch type of the retaining ring to be processed. For example, for a single bevel angle or natural cut, K = 1.4; for a double bevel angle, K = 2.8; for a single sector, K = 3; for a double sector, K = 4, etc. Then substitute the coefficient K, width W, and thickness T into the blanking force calculation formula: F = 1.23×W×T×K / 9.81. Here, 1.23 represents the general safety factor / process correction factor in the stamping industry, and 9.81 is the conversion factor between force and mass. Different machine models correspond to different blanking force thresholds. For example, F ≤ 2 corresponds to the 20 machine, 2 < F ≤ 4 corresponds to the 35 machine, 4 < F ≤ 6 corresponds to the 60 machine, 6 < F ≤ 11.28 corresponds to the 70 machine. Therefore, after calculating the blanking force of the retaining ring to be processed, compare it with the blanking force thresholds of different machine models, and determine the blanking force machine model according to the force value range.

[0044] Step S3014, select the machine model that simultaneously meets the cross-sectional area requirements, outer diameter requirements, and blanking force requirements among the cross-sectional area machine model, outer diameter machine model, and blanking force machine model as the final machine model.

[0045] Specifically, according to the three core processing constraints of the retaining ring cross-sectional area, outer diameter, and blanking force, respectively determine the lowest matching machine models that meet their respective requirements, and then select the largest one among the three lowest matching machine models as the final machine model. For example, if the cross-sectional area machine model is the 20 machine model, the outer diameter machine model is the 35 machine model, and the blanking force machine model is the 60 machine model, then the final machine model is the 60 machine model.

[0046] The final machine model can simultaneously meet all the constraint requirements of the cross-sectional area, outer diameter, and blanking force. However, instead of directly selecting the largest specification machine model, on the basis of ensuring that the processing capacity meets the standard, a smaller machine model with higher precision and better economy is preferably selected to avoid blindly selecting a large machine model resulting in a decrease in precision and cost waste, and to achieve the optimal balance of processing feasibility, product precision, and equipment use efficiency.

[0047] The method for automatically selecting and designing the spring machine die for the retaining ring provided in this embodiment realizes the systematic coverage and precise matching of the technological requirements in all stages of the retaining ring processing by screening the corresponding machine models based on the three core processing constraints of the cross-sectional area, outer diameter, and blanking force respectively, and then selecting the machine model that simultaneously meets all the constraints from the three candidate machine models. It avoids the insufficient processing capacity or waste of equipment resources that may be caused by single parameter selection, ensures that the selected machine model can meet both the structural dimension requirements for the forming of the retaining ring and the load requirements of the blanking process, effectively improves the scientificity and reliability of the machine model selection, and reduces the production risks and cost losses caused by selection mistakes.

[0048] Step S302, calculate the width-thickness ratio according to the width and thickness of the retaining ring to be processed, and judge whether it meets the fan-shaped processing requirements according to the width or width-thickness ratio.

[0049] Specifically, the above step S302 includes: Step S3021: If the width is less than the width threshold, or the width-to-thickness ratio is less than the width-to-thickness ratio threshold, then it is determined that the retaining ring to be processed does not meet the requirements for fan-shaped processing.

[0050] Specifically, by setting thresholds, specifications that cannot stably stamp a sector shape are excluded, ensuring the reliability of subsequent designs. If the width is less than the width threshold, or the width-to-thickness ratio is less than the width-to-thickness ratio threshold, it is determined that the retaining ring to be processed does not meet the requirements for sector shape processing. If it is not feasible, a prompt is issued. For example, if the width is <1.2mm or the width-to-thickness ratio is <1.37, it is determined that a sector shape cannot be stamped.

[0051] In step S3022, if the width is not less than the width threshold and the width-to-thickness ratio is not less than the width-to-thickness ratio threshold, then it is determined that the retaining ring to be processed meets the requirements for fan-shaped processing.

[0052] Specifically, if the width is not less than the width threshold and the width-to-thickness ratio is not less than the width-to-thickness ratio threshold, then the retaining ring to be processed is determined to meet the requirements for fan-shaped processing. For example, if the width is ≥1.2mm and the width-to-thickness ratio is ≥1.37, then it is determined that it can be stamped into a fan shape.

[0053] In step S303, if the requirements for fan-shaped processing are met, the inner arc angle of the fan-shaped cut is determined according to the basic parameters of the retaining ring to be processed and the final machine model. If the requirements for fan-shaped processing are not met, the punching angle is determined according to the cut type and application.

[0054] Specifically, the basic parameters also include: purpose and offset status. Step S303 above includes: Step S3031: Based on the purpose, offset state, final machine model, outer diameter, and width of the retaining ring to be processed, a multi-layer nested condition judgment logic is used to query the logic table to determine the inner arc angle of the corresponding fan-shaped cut.

[0055] Specifically, the mold parameter generation module has a built-in complex set of inner arc angle (R-angle value) values ​​for the fan-shaped cut, tailored to different machine models (20 / 35 / 60 / 70), different applications (hole / shaft), and different offset states (with / without offset). It employs a multi-layered nested conditional logic to query a logic table. This logic table exists in the form of multi-layered IF-ELSE conditional statements, accurately returning the corresponding R-angle value based on the input final machine model, the application of the retaining ring, the presence or absence of offset, the specific numerical range of the outer diameter, and the specific numerical range of the width.

[0056] This embodiment provides a method for automatically selecting retaining rings and designing spring machine molds. By setting width and width-to-thickness ratio thresholds as entry conditions for fan-shaped processing, it achieves automated and standardized judgment on whether the retaining ring is suitable for the fan-shaped cut, avoiding the subjectivity and error of manual experience judgment and ensuring process feasibility. Based on multi-dimensional parameters such as application, offset state, final machine model, outer diameter, and width, a multi-layer nested condition judgment logic is used to query a preset logic table to determine the inner arc angle of the fan-shaped cut. This achieves accurate and efficient matching of arc angle parameters, which not only meets the needs of different working conditions and structures, but also ensures the consistency and standardization of parameter design, effectively improving the accuracy and efficiency of fan-shaped cut mold design.

[0057] Step S3032: If the cut type is beveled, the punching angle is determined according to the application, including: if the application is a double bevel for shafts, the punching angle is 60 degrees; if the application is a double bevel for holes, the punching angle is 150 degrees.

[0058] Specifically, if the fan-shaped processing requirements are not met, the punching angle is determined based on the cut type and application. Cut types include: double fan, single fan, single bevel angle, double bevel angle, and natural cut. Among these, double fan and single fan are both fan shapes, and single bevel angle and double bevel angle are both bevel angles. If the cut type is bevel angle, the punching angle is determined based on the application. If the application is for a shaft with a double bevel angle, the punching angle is 60 degrees; if the application is for a hole with a double bevel angle, the punching angle is 150 degrees.

[0059] Step S304: Select or design a mold for the retaining ring to be processed based on the final machine model, the inner arc angle of the fan-shaped cut, the punching angle, and the basic parameters.

[0060] Specifically, step S304 includes: Step S3041: If the cut type is natural cut, then query the built-in rule table according to the final machine model, application, offset status, width, and thickness to generate mold parameters.

[0061] Specifically, if the cut type is natural cut, the built-in rule table is queried based on the final machine model, application, offset status, width, and thickness to generate mold parameters.

[0062] When the retaining ring cut type is a natural cut (no fan-shaped, no bevel, flat cut), the system automatically generates matching mold parameters. It reads key input information, final machine model, retaining ring application, offset status, width, and thickness, and then queries the built-in rule table for dedicated mold parameter rules for natural cuts. Using multi-layered conditional judgments, based on the above five basic data points, it automatically matches the corresponding mold structure, dimensions, fit clearance, cutting method, and other key mold parameters. The output mold parameters form a complete set that can be directly used for mold matching or mold manufacturing, serving as the basis for the next step.

[0063] Step S3042: Query the mold database or design a new mold based on the mold parameters.

[0064] Specifically, the system automatically matches mold parameters against the mold library; if no match is found, it automatically outputs new mold design specifications. The mold database matching system compares the generated model, application, offset, size, and natural cutting process parameters with the existing mold library item by item. If a match is successful, it directly outputs the available mold number and mold information, ending the process; if a match fails, it proceeds to the new mold design process.

[0065] The system automatically generates precise mold parameters for the natural cutting retainer ring based on multi-dimensional conditions, and then automatically matches the existing mold with the parameters; when there is no matching mold, it automatically outputs the design specifications, realizing the full automation of the natural cutting mold from parameters to selection / design.

[0066] All rules and experience regarding retaining ring mold selection and design are integrated into an intelligent system. Users only need to input basic parameters, and the system can automatically complete machine type determination, process feasibility analysis, and generation of core mold parameters (such as radius and angle), and can intelligently match existing molds or output design specifications for new molds. This greatly reduces manual intervention, avoids human error, significantly shortens the preparation time for new product introduction, and improves the standardization and automation level of production.

[0067] This embodiment provides a method for automatically selecting and designing retaining ring molds for spring machines. By directly binding the cut type and application to a fixed punching angle, it achieves standardized and automated configuration of punching process parameters, avoiding manual calculations and experience-based deviations, and ensuring the assembly performance and processing consistency of retaining rings. Simultaneously, for natural cut types, it generates mold parameters by querying a built-in rule table based on multi-dimensional parameters such as the final machine model, application, and offset status. Mold selection is then completed through database queries or new design. This achieves full automation of mold design for different cut types and accurately matches production conditions and structural requirements, significantly improving mold design efficiency and accuracy, reducing reliance on operator skills, and providing reliable support for stable mass production of retaining rings.
