Description

Although this improved method can avoid accidents caused by the wear state of the mold in advance, it is one-sided to predict the state of the mold from single data collection, when the process of the mold changes, other variables affect the state of the mold, and the relationship between single data and variables cannot be effectively judged, resulting in deviation in the prediction of the state of the mold, and the problem of being unable to effectively manage the subsequent state of the mold, such as the patent application with publication number CN119888277A, which discloses a mold full life cycle digital management method.

[0041] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0042] Please refer to Figure 1 The present application provides a mold whole life cycle management system based on the Internet of Things, which comprises a process mold analysis module, a stage process association module and a cycle dynamic maintenance module.

[0043] The process mold analysis module is configured to analyze all stages of the process in the whole life cycle of the mold, and based on the analysis results, obtain the front and rear associated processes of each stage, and obtain the front and rear associated parameters of each process.

[0044] The process mold analysis module includes a process mold analysis unit, which is configured with a process mold analysis strategy, which includes:

[0045] All stages in the whole life cycle of the mold are sequentially recorded as mold management stages MG1 to MG n ; For any mold management stage, all processes for processing the mold in the mold management stage are obtained, and based on the execution order of all processes in the mold management stage, all processes are sequentially recorded as mold processes MY1 to MY t ;

[0046] In the specific implementation process, for example, in a data analysis, the mold analyzed is a stamping mold, and through process analysis, it can be obtained that each stage in the stamping mold is a design and development stage, a manufacturing and processing stage, a batch service stage and a maintenance stage, so the above four can be sequentially recorded as mold management stages MG1 to MG4, that is, the value of n is 4.

[0047] For example, in the analysis process of the present embodiment, the design and development stage in the above four stages is analyzed, and through data acquisition, it is obtained that the processes contained in the design and development stage are: blade structure design, mold gap design and guide mechanism design; the above three processes can be sequentially recorded as mold processes MY1 to MY3, that is, the value of t is 3.

[0048] All mold processes of all mold management stages are obtained, and all mold processes are analyzed using a process parameter analysis method, and the front and rear associated parameters of each process are obtained.

[0049] The process parameter analysis method includes: for any mold process a: all mold processes in the mold management stage β except the mold process a are recorded as associated processes; the time when the mold process a is executed after the mold management stage β starts is recorded as T.

[0050] For any associated process: when the associated process is executed after the mold management stage β starts, if the time is less than T, the associated process is recorded as a front associated process; when the associated process is executed after the mold management stage β starts, if the time is greater than or equal to T, the associated process is recorded as a rear associated process.

[0051] In the specific implementation process, if the to-be-associated process analyzed is blade edge structure design, by analyzing the design and development stage where the to-be-associated process is located, when the design and development stage starts, the start time of the mold gap design and the guide mechanism design is after the start time of the blade edge structure design, so the mold gap design and the guide mechanism design can be recorded as the post-associated process of the blade edge structure design.

[0052] The process parameter analysis method further includes: for any one to-be-associated process: when the to-be-associated process is a pre-associated process, recording the to-be-associated process as a directional process and recording the mold process a as a variable direction process; when the to-be-associated process is a post-associated process, recording the to-be-associated process as a variable direction process and recording the mold process as a directional process.

[0053] In the specific implementation process, by marking the directional process and the variable direction process, the purpose is to mark the process that has been determined and the process that may have variables. For example, for blade edge development and design and mold gap design, during the design and development stage, the start time of the mold gap design is after the start time of the blade edge structure design, so when the blade edge structure design starts, the parameters in the mold gap design will affect the mold obtained from the blade edge structure design as variables. Therefore, at this time, the blade edge structure design should be recorded as a directional process, that is, a process with determined parameters, and the mold gap design should be recorded as a variable direction process, that is, a process with parameters that may change, and then subsequent analysis is performed. In summary, in the analysis process of the present embodiment, because the mold gap design and the guide mechanism design are recorded as the post-associated process of the blade edge structure design, during the analysis, the mold gap design and the guide mechanism design are variable direction processes, and the blade edge structure design is a directional process.

[0054] The parameters in the directional process that are allowed to be collected in real time by the Internet of Things are recorded as directional collection parameters, and the parameters in the variable direction process that are allowed to be collected in real time by the Internet of Things are recorded as variable direction collection parameters. The use range of the directional collection parameters and the variable direction collection parameters in the process is obtained respectively and recorded as a directional parameter range and a variable direction collection range.

[0055] The process parameter analysis method further includes: for any one directional collection parameter, based on the historical record data of the mold full life cycle, obtaining all the values of the directional collection parameter that have been selected for use in the directional parameter range, and recording them in order from small to large as directional allowed values DY1 to directional allowed values DY e ; based on AI, obtaining the association logic of all variable direction collection parameters and directional collection parameters, obtaining the influence parameters of each variable direction collection parameter and directional collection parameter after association based on the association logic, and recording them in order as variable direction influence parameters BY1 to variable direction influence parameters BY p , where p is the number of variable direction collection parameters.

[0056] In specific implementation, such as the analysis in this embodiment, one directional acquisition parameter is the cutting edge wear amount in the cutting edge structure design, and the other directional acquisition parameter is the stamping speed in the die clearance design process. If the cutting edge wear amount is large and the stamping speed is large, it will cause the cutting edge wear rate to increase. Therefore, the lubrication frequency should be increased to reduce the cutting edge wear rate. Thus, through the above analysis, the influence parameter after the correlation between the cutting edge wear amount and the stamping speed can be obtained as the lubrication frequency, which can be used as a directional influence parameter. For other directional acquisition parameters when the cutting edge wear amount is the directional acquisition parameter, such as the stamping angle, die clearance, and stamping force, the corresponding directional influence parameters can be obtained by simulating the design and development stage using AI.

[0057] For any directional allowable value DY q And any one of the directional influence parameters BY u Establish a Cartesian coordinate system, denoted as the orientation analysis coordinate system, where the units of the X-axis and Y-axis of the orientation analysis coordinate system are respectively the units of the directional influence parameter BY. u The unit and the direction-changing influence parameter BY u The unit of the corresponding directional acquisition parameter, where u is a positive integer less than or equal to p and greater than or equal to 1.

[0058] Process parameter analysis methods also include: obtaining the allowable orientation value DY under standard conditions within the orientation analysis coordinate system based on the Internet of Things. q The parameter BY remains unchanged and has a directional influence. u When the corresponding directional acquisition parameter increases within the directional acquisition range, the directional influence parameter BY... u With the change of direction influence parameter BY u The corresponding relationship curve of the directional acquisition parameters is recorded as the directional analysis curve;

[0059] In the specific implementation process, the standard case is as follows, excluding the subsequently proposed directional influence parameter BY. u The corresponding directional acquisition parameters increase within the directional acquisition range, while other parameters and the environment of the process are within the specified range. For example, in the analysis of this embodiment, the directional acquisition parameters and directional acquisition parameters analyzed are the cutting edge wear and the stamping speed, respectively, and the obtained directional allowable value is 0.006mm. The directional acquisition range of the stamping speed is [20 times / min, 40 times / min]. Therefore, when the cutting edge wear in the cutting edge structure design is 0.006mm, the relationship curve between the stamping speed and the lubrication frequency should be obtained when the stamping speed increases within [20 times / min, 40 times / min]. Figure 2 The directional analysis curve DF in the middle;

[0060] Obtain the directional influence parameters BY u The range that is allowed to be used in the process is denoted as the change of influence range; the change of maintenance curve in the directional analysis curve is obtained, wherein the abscissa of all points in the change of maintenance curve is outside the change of influence range;

[0061] In the specific implementation process, by obtaining the change-direction maintenance curve in the directional analysis curve, we can use the subsequent real-time parameters to determine whether mold maintenance is required based on the actual situation of the real-time parameters. That is, when the value of the change-direction influence parameter is in the change-direction maintenance curve, mold maintenance is required based on the change-direction influence parameter. For example, if the change-direction influence parameter is the lubrication frequency, and the value of the change-direction influence parameter is in the change-direction maintenance curve, it means that the lubrication frequency exceeds the allowable range, which will affect the wear state of the cutting edge. Therefore, the worn cutting edge should be replaced or manually lubricated.

[0062] The process parameter analysis method also includes: obtaining the change-direction maintenance curves of all change-direction influence parameters corresponding to each directional allowable value and directional acquisition parameter; when any directional allowable value has any corresponding change-direction maintenance curve, the directional acquisition parameter is recorded as the pre-correlation parameter of the change-direction acquisition parameter, and the change-direction acquisition parameter is recorded as the post-correlation parameter of the directional acquisition parameter;

[0063] In the specific implementation process, only the directional acquisition parameters with change-of-direction maintenance curves are used as the pre-association parameters. The reason is that if none of the directional allowable values ​​in the directional acquisition parameters have corresponding change-of-direction maintenance curves, it means that the directional acquisition parameters do not have associated parameters, or that the directional acquisition parameters and their associated parameter U will not be outside the range of change-of-direction influence during the use of the parameters. That is, even if the parameter U changes in the subsequent process, it will not affect the equipment or mold related to parameter U. Therefore, there is no need to mark the directional acquisition parameters that do not have corresponding change-of-direction maintenance curves.

[0064] Obtain the pre-association parameters and post-association parameters corresponding to mold process α and all processes to be associated. Based on the processing method of mold process α, obtain the pre-association parameters and post-association parameters of all mold processes.

[0065] The stage process association module is used to analyze the pre-association parameters and post-association parameters of each process, and obtain the pre-association features and post-association features of each process based on the analysis results;

[0066] The stage process association module includes a stage process association unit, which is configured with a stage process association strategy. The stage process association strategy includes: For any mold process α: For any pre-association parameter of mold process α: Obtain the directional acquisition parameter corresponding to the pre-association parameter in mold process α that has a directional maintenance curve, and record the value of the ordinate at the intersection of the directional analysis curve and the directional maintenance curve corresponding to the directional acquisition parameter as the identification feature of the directional acquisition parameter, and record the directional allowable value corresponding to the directional analysis curve as the identification feature of the pre-association parameter;

[0067] In specific implementation, such as in the analysis of this embodiment, for the pre-correlated parameter "edge wear amount", the corresponding directional maintenance curve is as follows: Figure 3 The curve WE in the figure, and the curve WE is Figure 2 Part of the directional analysis curve DF, and Figure 3 The dashed curve in the figure is the curve other than the change-of-direction maintenance curve in the directional analysis curve. Therefore, the vertical coordinates of point ST1 and point ST2, 29 times / min and 33 times / min respectively, can be used as the identification features of the change-of-direction acquisition parameter "stamping speed". The directional allowable value of cutting edge wear, 0.006mm, is recorded as the identification feature of the pre-correlation parameter.

[0068] Obtain the identification features of the variable acquisition parameters corresponding to all the preceding associated parameters of the mold process α, as well as the identification features of the preceding associated parameters, and record them as the preceding associated features of the mold process.

[0069] The stage process association strategy also includes: for any post-association parameter of mold process α: obtain the directional acquisition parameter of the existence of the change direction maintenance curve in mold process α corresponding to the post-association parameter, and record the directional allowable value corresponding to the change direction maintenance curve as the identification feature of the directional acquisition parameter, and record the value of the ordinate at the intersection of the change direction maintenance curve and the directional analysis curve as the identification feature of the post-association parameter.

[0070] Obtain the identification features of the directional acquisition parameters and the identification features of the post-correlation parameters corresponding to all post-correlation parameters of the mold process α, and record them as the post-correlation features of the mold process.

[0071] The periodic dynamic maintenance module is used to acquire real-time parameters of equipment in all stages of the mold's entire life cycle using the Internet of Things, and to perform dynamic maintenance on the equipment in the process based on the real-time parameters and the pre-process and post-process correlation features of each process.

[0072] The periodic dynamic maintenance module includes a periodic dynamic maintenance unit, which is configured with a periodic dynamic maintenance strategy. The periodic dynamic maintenance strategy includes:

[0073] The Internet of Things (IoT) is used to acquire parameters that can be collected in real time within the equipment during all stages of the mold's entire lifecycle, and these parameters are recorded as real-time parameters for each parameter. For any mold process α: when any pre-associated parameter of mold process α satisfies that the real-time parameter of the variable acquisition parameter corresponding to the pre-associated parameter and the real-time parameter of the pre-associated parameter are equal to the identification features of the variable acquisition parameter corresponding to the pre-associated parameter and the identification features of the pre-associated parameter, respectively, the variable influence parameter corresponding to the horizontal axis in the directional analysis curve corresponding to the variable acquisition parameter is recorded as the parameter to be maintained, and the equipment associated with the parameter to be maintained is maintained based on the IoT.

[0074] In the specific implementation process, for example, during a data analysis, it was found that during the design and development stage, the real-time parameters of the change direction acquisition parameter "stamping speed" and the real-time parameters of the cutting edge wear amount corresponding to the pre-correlation parameter "cutting edge wear amount" were 29 times / min and 0.006mm, respectively. Since 29 times / min and 0.006mm are equal to the identification characteristics of the change direction acquisition parameter and the identification characteristics of the pre-correlation parameter corresponding to the cutting edge wear amount obtained in the above analysis, it indicates that the change direction influence parameter "lubrication frequency" is about to be outside its corresponding change direction influence range. Therefore, the lubrication frequency should be recorded as a parameter to be maintained, and the equipment associated with the lubrication frequency should be maintained based on the Internet of Things, such as replacing worn cutting edges or performing manual lubrication.

[0075] When any post-correlation parameter of the mold process α satisfies that the real-time parameter of the directional acquisition parameter corresponding to the post-correlation parameter and the real-time parameter of the post-correlation parameter are equal to the identification features of the directional acquisition parameter corresponding to the post-correlation parameter and the identification features of the post-correlation parameter, respectively, the directional influence parameter corresponding to the horizontal axis in the directional analysis curve with the real-time parameter of the directional acquisition parameter as the directional allowable value is recorded as the parameter to be maintained, and the equipment associated with the parameter to be maintained is maintained based on the Internet of Things.

[0076] Working principle: First, the process of all stages in the entire life cycle of the mold is analyzed, and based on the analysis results, the pre-processes and post-processes of each stage are obtained, as well as the pre-processes and post-processes of each process. Then, the pre-processes and post-processes of each process are analyzed, and the pre-processes and post-processes of each process are obtained based on the analysis results. Finally, the Internet of Things is used to obtain the real-time parameters of the equipment in all stages in the entire life cycle of the mold, and based on the real-time parameters and the pre-processes and post-processes of each process, the equipment in the process is dynamically maintained.
