[0017] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0018] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention.

The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0020] Reference Figure 1 , as one embodiment of the present invention, provides a method for optimizing the stamping process of a mold for a fuel tank housing of a new energy plug-in hybrid vehicle, the method comprising the following steps: Step 1: Design a multi-station mold suitable for the fuel tank housing and install it on the stamping line. Each station mold is responsible for a specific molding step, and the installed transmission system transfers the material from one station to the next for continuous stamping.

[0021] Step 2: Build an integrated detection mechanism, that is, when the oil pan is stamped in multiple stations, configure the detection parameters, conduct quality inspection immediately after the workpiece passes through each station, and adjust the stamping parameters of the next station according to the inspection results.

[0022] Specifically, the steps of the integrated detection mechanism are: S201: Collecting detection parameters through sensors , including but not limited to: material thickness, deformation, temperature change and punching force.

[0023] S202: Introducing time decay factor Represents the attenuation characteristics of the detection parameters over time.

[0024] S203: Considering noise and interference factors, the periodic fluctuation characteristics in the signal are described by a modulation function f; the expression of the modulation function f is: , where α is the amplitude coefficient of the modulation signal, is the modulation frequency of the detection parameter j, is the phase offset, which indicates the initial phase of the signal.

[0026] S205: Construct a dynamic adjustment function based on the comprehensive influence of the detection parameters , used to adjust the stamping parameters of the station after detection; adjustment function The expression is: ,in, It represents the real-time pressure change rate of the i-th station, and the calculation formula is expressed as: ,in, is the reference parameter of the i-th station, which is used for standardized adjustment; this adjustment function is used to dynamically adjust the parameters of the stamping station according to the detection results to optimize the production process.

[0027] S206: Finally, the detection data of the entire monitoring period T is integrated to obtain the final quality detection reflection value , the expression of quality detection reflection value is: .

[0028] Minimum value: When the detection parameters are extremely stable and the deviation is minimal (i.e. D(i,j,t)≈R(i)), the Q(i) value is close to zero, indicating that no major adjustments are required; Maximum value. When there is an extreme deviation in the detection parameters (such as a sudden change in material thickness or deformation exceeding the standard), Q(i) will reach a high value, indicating that the stamping parameters of the next station need to be significantly adjusted.

[0029] Step 3: Build a multi-station intelligent adjustment mechanism, that is, record the stamping parameters of each tank shell stamping station in real time, and automatically adjust the stamping parameters of each station according to the quality inspection results to ensure the best process conditions.

[0030] The multi-station intelligent adjustment mechanism includes the following steps: S301: Define the real-time stamping parameters for each station , this parameter is a function of time t and changes dynamically with time; Stamping parameters The expression is: ,in, represents the initial stamping parameters, is the rate of change of the parameters of the ith station at time t.

[0031] S302: Based on the comprehensive impact obtained in step 2 and quality inspection reflection value , construct an impact factor To express the comprehensive influence on stamping parameters; Impact Factor The expression is: , where k is an adjustment coefficient used to balance the comprehensive influence and stamping parameters.

[0032] S303: Based on the impact factor , build an automatic adjustment function for stamping parameters , automatic adjustment function The expression is: ,in, It is a tuning parameter used to control the adjustment amplitude.

[0033] S304: Based on all the parameters obtained above, calculate the stamping parameter adjustment amount of each station , stamping parameter adjustment amount The final expression of is: ,in, Used to control the adjustment direction. When it is positive, When it is a positive value, it means increasing the stamping parameters, and when it is a negative value, A negative value means reducing the stamping parameters.

[0034] Set the first threshold value T1 and the second threshold value T2 of the quality detection reflection value. If the quality detection reflection value If it is greater than the set first threshold T1, the quality inspection result of the current station i is judged to be excellent, and the current stamping parameters are maintained. No change, or only minor adjustments; If the quality test reflects the value If the value is less than the set second threshold value T2, the quality inspection result of the current station iii is judged to be unqualified, and the stamping parameters are adjusted immediately. To improve the quality of finished products; If the quality test reflects the value Between the second threshold value T2 and the first threshold value T1, it is determined that the quality inspection result of the current station i is average, and the stamping parameters of the current station are Make appropriate adjustments and continue to monitor; If the quality test reflects the value If the value is greater than the first threshold value T1 for N consecutive times, it is determined that the process parameters of the current station i are stable and of good quality, and the current stamping parameters are enhanced. to increase the confidence of the process and reduce the sensitivity of future adjustments to maintain process stability; If the quality test reflects the value If the value is less than the second threshold value T2 for N consecutive times, it is determined that there is a persistent problem with the process parameters of the current station i, and the current stamping parameters are improved. The adjustment weights are adjusted and a more aggressive parameter correction strategy is immediately adopted, while increasing the frequency and strictness of inspections on subsequent workstations.

[0035] Reference Figure 2 It can be seen that the green dotted line represents the first threshold value T1 (set to 0.90). When the quality detection value is higher than this threshold, such as the detection value of 0.92 at the second station, it indicates that the workpiece quality is good and the process parameters may only need fine-tuning; the red dotted line represents the second threshold value T2 (set to 0.85). When the detection value is lower than T2, such as the detection value of 0.80 at the first station, the system will immediately make substantial adjustments to the process parameters of the station to correct the production problem; for detection values ​​between T1 and T2 (such as the detection value of 0.87 at the third station), the system will make appropriate adjustments and closely monitor the detection results of subsequent stations.

[0036] An optimization system for the stamping process of the fuel tank housing mold of a new energy plug-in hybrid vehicle based on the above optimization method includes the following functional modules: The multi-station mold design and control module designs and controls the multi-station mold for forming the fuel tank shell, ensuring that the mold of each station performs specific forming steps and realizes continuous material transfer through the transmission system; the quality inspection and feedback module performs quality inspection on the workpieces completed at each station and generates feedback based on the inspection results to adjust the stamping parameters; the intelligent parameter adjustment module adjusts the stamping parameters of each station in real time based on the quality inspection results to ensure the optimization of process conditions; and the comprehensive influencing factor calculation module calculates the comprehensive influencing factor of each station, evaluates the impact of the current station parameter adjustment on the subsequent stations and the overall process, and ensures that the process conditions of the subsequent stations are optimized.

[0037] In summary, the present invention improves production efficiency through multi-station mold design: by improving the traditional single-station stamping into multi-station stamping, multiple processes of complex oil tank shells can be completed continuously on one production line, reducing the transfer time and error accumulation of workpieces between different processes, and by constructing an integrated quality inspection mechanism: an instant quality inspection system is set after each station, so that the quality status of the workpiece after each station can be immediately fed back, and the stamping parameters of the next station are dynamically adjusted according to the inspection results, avoiding the production of defective products and improving the product qualification rate.
