Thus, the following detailed description of the embodiments of the invention, as presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. All other embodiments, which can be made by a person skilled in the art without making any inventive effort, are intended to be within the scope of the present invention.
It should be noted that: like reference numerals and letters denote like items in the following figures, and thus once an item is defined in one figure, no further definition or explanation thereof is necessary in the following figures. Meanwhile, in the description of the present invention, the terms "first", "second", and the like are used only to distinguish the description, and are not to be construed as indicating or implying relative importance.
Referring to fig. 1, in this embodiment, a method for optimizing resilience of a stamping part is provided, and fig. 1 shows a flowchart of the method, which specifically includes:
step S10: establishing a simulation model according to the attribute of a plate material for producing the target part and the attribute of a die for producing the target part;
step S20: performing simulation and continuously adjusting process parameters to enable a simulation result to meet preset requirements, and obtaining target process parameters corresponding to a minimum first rebound value, wherein the first rebound value is the minimum value of rebound amounts obtained in the current simulation process;
step S30: if the first rebound value is larger than the rebound threshold value, continuing to perform simulation based on the target process parameter and continuously adjusting the die parameter, so that a simulation result meets a preset requirement, and obtaining a target die parameter corresponding to the minimum second rebound value; the second rebound value is the minimum value of rebound amounts obtained in the current simulation process, and is smaller than the rebound threshold value;
step S40: and manufacturing the target part according to the target technological parameters and the target mold parameters.
In step S10, the target part may be a stamping such as a cover of an automobile.
Before step S10 is performed, it is necessary to detect the rebound of the target part to determine whether or not the target part needs to be rebound-controlled. Specifically, referring to fig. 2, before step S10, the method further includes:
step S101: and carrying out a stamping experiment according to the plate material for producing the target part and the die for producing the target part to obtain a sample part corresponding to the target part. Namely, the plate material of the target part and the die of the target part are directly adopted for experimental production.
Step S102: and carrying out three-dimensional scanning on the sample part to obtain a three-dimensional model of the sample part.
Specifically, three-dimensional scanning is carried out on the sample part, and a scanning result is obtained; and denoising the scanning result to obtain a three-dimensional model. For example, a professional three-dimensional scanning device, specifically, a three-dimensional inverse device of the creation company is used to scan the surface of the part, and then the scanning result obtained by the scanning is subjected to denoising processing to obtain the contour (three-dimensional model) of the part, so as to ensure the contrast accuracy in step S103.
Step S103: and comparing the three-dimensional model with the standard model of the target part to obtain a maximum rebound value on the sample part, wherein if the maximum rebound value is larger than a rebound threshold value, a simulation model is established according to the attribute of the plate material of the production target part and the attribute of the die of the production target part.
If the maximum springback value is greater than the springback threshold value, the step S10 is needed to be executed, springback optimization is started, and the springback threshold value is a limit value for judging whether the springback amount of the target part is qualified.
In step S103, the model comparison method is to import the obtained three-dimensional model into professional comparison software (such as geomic Studio) and compare the three-dimensional model with a standard model (such as CAD standard model) of the part.
By obtaining the sample parts, the model parameters of the simulation model can be determined more quickly and accurately, and the efficiency and the accuracy of the subsequent simulation are improved.
In step S10, sheet properties include, but are not limited to: size, material, strength, etc. of the plate; the properties of the mold include, but are not limited to, the size of the mold; simulation parameters, such as grid type and number, need to be set according to actual stamping conditions when the simulation model is built. In addition, the gravity of the plate and the mould is easy to ignore when the simulation model is built, and the influence of gravity on the rebound amount is not easy to think, but the gravity still has a certain influence on the deformation amount, so that the gravity parameter (such as the weight of the plate or the local weight of the edge) needs to be set for the simulation model according to the attribute (such as the quality of the plate) of the plate of the production target part.
In this embodiment, the setting of the simulation parameters may be obtained by the following steps, that is, step S10 may include:
a1, establishing an initial model according to the attribute of the plate material for producing the target part and the attribute of the die for producing the target part.
A2, adopting an initial model to carry out simulation of the sample part so that the similarity between a simulation result and the sample part reaches a similarity threshold value, and obtaining simulation parameters of the current initial model.
Because the simulation result cannot be completely identical to the sample part and is only infinitely close, a similarity threshold can be set for accuracy control, for example, the similarity reaches 99%, and the simulation result can be considered to be identical to the sample part.
A3, taking the initial model with the simulation parameters as the simulation model.
Through the specific experiments of the steps S101-S103 and the simulation of the steps A1-A3, the simulation model is ensured to be basically consistent or close enough to the working condition of actual production, the simulation can be performed more quickly, and the efficiency and the precision of rebound optimization of the target part are improved.
Step S20: and performing simulation and continuously adjusting the process parameters to enable the simulation result to meet the preset requirement and obtain the target process parameters corresponding to the minimum first rebound value.
In step S20, process parameters are adjusted, including but not limited to: and adjusting the blank holder force, the friction coefficient and the stamping speed. The process parameters are easier to control relative to the mold parameters and thus in this embodiment adjustment of the process parameters needs to be prioritized. After each time of technological parameter adjustment, one simulation is carried out to obtain a new rebound quantity. Finally, the relation between the process parameters of the press forming and the rebound value can be found, and the minimum first rebound value can be obtained therefrom, wherein the first rebound value is the minimum value of the rebound amounts obtained in the simulation process of the step S20.
In the simulation process, the influence rule of blank holding force and friction coefficient on rebound maximum value can be obtained by combining a response surface method and an optimization method, wherein the optimization method can adopt a multi-objective genetic optimization method such as NSGA-II (non-dominant ordered genetic algorithm with elite strategy) and the like. Because the thinning is typically severe when rebound is reduced, it is necessary to perform multi-objective optimization of rebound and thinning to obtain a compromised or optimal solution.
In step S20, excessive thinning, wrinkling, etc. may occur due to the modification of process parameters (and the like of subsequent die parameters) while the target part is being press-formed. Therefore, the simulation result needs to meet the preset requirements, that is, the basic quality during the stamping forming is ensured, such as the thinning cannot be too serious, the wrinkling cannot be performed, and the like.
If the first rebound value is smaller than the rebound threshold value, the process parameter is used to enable the produced target part to meet the precision requirement, and practical experiments and production can be carried out. If the first springback value is greater than the springback threshold, it indicates that the adjustment of the press forming process parameters alone cannot meet the requirements, and further die parameter adjustment is required, i.e., step S30 is performed.
Step S30: if the first rebound value is larger than the rebound threshold value, continuing to perform simulation based on the target process parameter and continuously adjusting the die parameter, so that a simulation result meets a preset requirement, and obtaining a target die parameter corresponding to the minimum second rebound value.
In step S30, the second rebound value is the minimum value among the rebound amounts obtained in the simulation of step S30.
In step S30, the adjusted die parameters include a draw bead parameter and a die face parameter. Because the draw bead parameters are easier to modify relative to the die face parameters. Therefore, the rebound amount can be adjusted by modifying the draw bead parameters. If the rebound can be controlled by adjusting the draw beads, the modification of the die surface of the die is not needed, and the workload can be reduced.
Thus, step S30 specifically includes:
and continuously carrying out simulation based on the target technological parameters and continuously adjusting the draw bead parameters, so that the simulation result meets the preset requirement, and obtaining the target draw bead parameters corresponding to the minimum second rebound value. The second rebound value is smaller than the rebound threshold value, and the target process parameter can be considered to be matched with the current target draw bead parameter, so that the produced target part meets the precision requirement, and an actual experiment or production can be carried out.
The simulation result is required to meet the preset requirements, for example, the thinning cannot be too serious, wrinkling cannot be performed, and the like, as in step S20. During adjustment, the height of the draw bead, the radius of the draw bead and the like can be specifically adjusted.
If the second rebound value cannot be smaller than the rebound threshold value by simply adjusting the draw bead parameters in the die surface parameters, the following adjustment steps can be performed:
b1, continuously performing simulation on the basis of the target technological parameters and continuously adjusting the draw bead parameters so that a simulation result meets preset requirements to obtain target draw bead parameters;
b2, judging whether the current minimum rebound value is larger than the rebound threshold value or not;
and B3, if so, continuing to perform simulation based on the target process parameter and the target draw bead parameter and continuously adjusting the die surface parameter, so that a simulation result meets a preset requirement, and obtaining the target die parameter corresponding to the minimum second rebound value.
Finally, the second rebound value should be made smaller than the rebound threshold in step B3.
Specifically, in step B3, the die surface parameters may be modified according to the amount and the position of the rebound during simulation, so as to compensate for the rebound. After the die surface parameters are modified, simulation is performed to obtain a new rebound quantity. Preferably, simulation software (such as auto form) with optimization function and die face rebound compensation function can be used. In addition, the geometric modification of the die can be performed in CAD software, and then the die surface is imported into simulation software for simulation analysis. The spring back compensation of the die face can reduce the spring back until the requirement is reached.
In step S40, the target process parameter and the target mold parameter are optimized parameters, and the parameters are used to manufacture (experiment or production) the target part, so that rebound can be effectively controlled, and quality of the target part is improved.
In summary, according to the stamping part rebound optimization method provided by the application, the simulation precision is ensured by establishing a model for the actual plate material and the die for producing the target part; and then, sequentially optimizing the process parameters and the mold parameters by simulation, and determining a target process parameter corresponding to the minimum first rebound value and a target mold parameter corresponding to the minimum second rebound value, wherein the second rebound value is smaller than the first rebound value. The finally obtained target process parameters and the target mold parameters are guaranteed to be optimal parameters, and finally the rebound of the target part can be controlled more accurately according to the generation of the target part according to the target process parameters and the target mold parameters, so that the processing quality of the target part is guaranteed.
