Description

Technical Field

[0001] The invention relates to the field of automobile processing, and in particular to an automated production and stamping method for automobile heater heat exchanger accessories with reinforcing ribs. Background Art

[0002] Car heater heat exchanger with reinforcement accessories such as Figure 1 As shown, the traditional stamping process is usually adopted, which involves multiple steps, including first cutting a notch on the strip, stamping out a strip reinforcement rib, bending the two ends of the strip, and finally cutting to form a complete accessory unit. The current processing method generally adopts a single process mode, that is, each process uses different molds and stamping equipment to complete the required processing steps. The conversion between each mold and process is not only time-consuming, but also the cost of manufacturing and installing multiple sets of molds and equipment is high; although it can achieve independent processing of each process, the accompanying problem is that each process needs to be re-positioned and aligned, which not only leads to low production efficiency but also makes it difficult to ensure processing accuracy, and it is easy to have cumulative positioning errors, increasing the probability of defective products. Secondly, the existing processing method lacks a real-time monitoring system for important parameters that affect processing quality, such as punching pressure and punching depth, which may cause damage to the mold and the strip, making it difficult to ensure that the quality of stamped accessories meets the design requirements, and it is difficult to effectively optimize the stamping process, which limits the improvement and innovation of the production process and is not conducive to data resource collection and quality problem analysis.

[0029] As a preferred technical solution of the present invention, the design requirements of the punching force F' and the punching depth L' of the upper die in step S6 are specifically as follows:

[0030] F'<F' min Or L'<L' min or k'<k' min , it is judged that the stamping is insufficient, the control component stops responding and sends out an alarm signal to notify the operator to make corresponding adjustment measures; F' min ≤F'≤F'max And L' min ≤L'≤L' max And k' min ≤k'≤k' max , it is judged that the stamping is normal, the control component does not respond, and continues to the next stamping work; F'>F' max or L'>L' max or k'>k' max , it is judged as over-stamping, the control component stops responding and sends out an alarm signal to notify the operator to make corresponding adjustment measures; where k' is the ratio of the overall stamping depth L' to the overall stamping force F', F' min and F' max are the minimum and maximum values ​​of the overall punching force design range, L' min and L' max are the minimum and maximum values ​​of the overall stamping depth design range, k' min and k' max are the minimum and maximum values ​​of the ratio design range respectively;

[0031] Among them, the ratio k' is compared with the ratio design range to determine whether the stamping work meets the requirements. When the stamping equipment works normally, the overall stamping force F' and the overall stamping depth L' of the upper die satisfy the following relationship:

[0032]

[0033] Wherein, γ1, γ2, γ3 are adjustment coefficients, t is the thickness of the material strip, and B is the yield strength of the material strip.

[0034] As a preferred technical solution of the present invention, step S6 also includes the step of adaptively controlling processing parameters, by arranging a graphics acquisition device at each workstation to capture the edge and contour of the material strip in real time, and feeding back to the control component to calculate and process the actual thickness of the material strip. The control component dynamically adjusts the stamping force F' and stamping depth L' of the upper mold according to the actual thickness size data, material strip characteristics and process requirements.

[0035] As a preferred technical solution of the present invention, step S8 specifically includes the following steps:

[0036] S801, collecting stamping data of each process, wherein the stamping data includes the feeding speed v, the stamping force F' and the stamping depth L' of the upper die, the thickness and hardness of the material strip, the monitoring results and the adjustment measures of the control component;

[0037] S802, simulation: using a machine learning algorithm to analyze and simulate the collected stamping data, and establish a prediction model based on the stamping data;

[0038] S803, calculating abnormality probability: predicting the workpiece state during the stamping process through the prediction model and calculating the abnormality probability of the accessory, the working state including the shape, size and processing quality of the material strip;

[0039] S804, processing parameter optimization: the control component automatically adjusts the processing parameters according to the abnormal probability of the accessory.

[0040] As a preferred technical solution of the present invention, the feeder completes the conveyance of the material belt through a driving wheel and a driven wheel arranged at the output port, the material belt is placed between the driving wheel and the driven wheel, and the driving wheel and the driven wheel are both provided with Hall sensors electrically connected to the control component, which are used to monitor the rotation speed v1 of the driving wheel and the rotation speed v2 of the driven wheel respectively;

[0041] When |v1-v2|≤v3, it indicates that the feeding is normal and the control component does not respond;

[0042] When v1-v2>v3, it indicates that the material strip is stuck during the stamping process, and the control component responds by stopping the machine and prompting the operator to replace the spring plunger;

[0043] When v1-v2<v3, it indicates that the material strip slips during the stamping process, and the control component responds by stopping the machine and notifies the operator that the material strip has been transferred to the end, and replaces the new material strip in time;

[0044] Among them, v3 is the speed deviation threshold, the unit is rad / s, and it satisfies the following relationship:

[0045]

[0046] Wherein, r is the radius of the driving wheel, b is the acceptable length error of a single accessory, in mm, and s is the moving rhythm of the material strip, in s.

[0047] The beneficial effects of the present invention are:

[0048] (1) The present invention combines important processing steps such as cutting, punching reinforcement, bending, cutting and stripping into one mold on the same stamping equipment, thereby realizing continuous operation of the processing flow. That is, multiple processes are completed in one mold, thereby realizing a high degree of integration of the processing flow. Compared with the traditional single-process processing technology, the present invention can stamp individual parts separately, thereby greatly improving production efficiency and shortening production cycle. During the processing, each process can be closely connected, and there is no need to transfer and reposition the semi-finished products between processes. This not only reduces processing errors, but also reduces the time cost of mold replacement and debugging.

[0049] (2) By adding optical sensors and piezoresistive flexible sensors, the position deviation and pressure distribution deviation of the material strip in each process are continuously monitored, which helps to timely detect and correct deviations, avoid processing defects caused by position errors or excessive flatness of the material strip, and achieve accurate positioning of the material strip during the stamping process and ensure the stability of the stamping quality.

[0050] (3) The present invention installs a load sensor and a displacement sensor on the upper mold to monitor the working status of the mold in real time. By analyzing the collected data, the control component dynamically adjusts the processing parameters, such as the punching force F' and the punching depth L' of the upper mold, to optimize the processing process, ensure that the working status of the mold is always in the best, ensure the accuracy and consistency of the stamping process, and achieve high-precision monitoring; in addition, the data collected by the load sensor and the displacement sensor can also be used to predict the wear and maintenance needs of the mold. Before problems occur in the mold, timely maintenance and care can be performed based on data prediction, thereby effectively reducing unexpected downtime.

[0051] (4) A joint control relationship between stamping force and stamping depth is established to obtain an adaptive control range, which can adapt to different strip materials and thicknesses, as well as different processing requirements. It has good versatility and flexibility, can ensure the stamping quality under different conditions, and avoid defects caused by parameter mismatch.

[0052] (5) During the stamping process, the movement accuracy of the material belt is very important. If the material belt fails to be transmitted at a predetermined precise speed, it may cause deviation in the position of the stamping die, affecting the processing accuracy of the workpiece. The present invention monitors the speed difference between the driving wheel and the driven wheel of the feeder to detect the state of the material belt in real time, ensuring that each workpiece is accurately aligned with the die, avoiding accuracy problems caused by speed differences. Once the speed difference exceeds the set threshold, the control system can immediately identify problems with the material belt, such as sticking or slipping, and respond quickly to avoid serious faults and ensure smooth production processes. Secondly, long-term data accumulation and analysis of the changing trend of the speed difference can be used to accurately predict the aging cycle of the spring plunger and the best time to replace the material belt, arrange equipment maintenance and replacement of the material belt in advance, and improve the overall operating efficiency of the production line.

DETAILED DESCRIPTION

[0061] The specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments given here are only used to illustrate and explain the present invention, and cannot be used to limit the present invention.

[0062] It should be noted that many specific details are set forth in the following description to facilitate a full understanding of the present invention. However, the present invention may also have other implementations and variations thereof. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0063] like Figures 1 to 6 As shown, an automated production and stamping method for a car heater heat exchanger with a reinforcing rib accessory 3 comprises the following steps:

[0064] S1. Die debugging: Perform preliminary debugging on the die on the stamping equipment 1 and check the die gap and alignment;

[0065] The stamping equipment 1 is provided with a first fixed plate 11, a pressing plate 12 and a second fixed plate 13 from top to bottom. The first fixed plate 11 is controlled by a driving component (not shown in the figure) to move up and down. The driving component is electrically connected to the control component (not shown in the figure). The first fixed plate 11 is used to fix the upper mold 14. The upper mold 14 includes a cutting insert 141, a reinforcing rib insert 142, a bending insert 143 and a cutting insert 144 in sequence according to the processing steps; the pressing plate 12 is movably connected to the first fixed plate 11, and the pressing plate 12 is provided with corresponding to the cutting insert 141, the reinforcing rib insert 142, the bending insert 143 and the cutting insert 144 and for the cutting insert 141, the reinforcing rib insert The second fixing plate 13 is used to fix the lower mold 15, and the lower mold 15 includes a cutting blanking die 151, a reinforcing rib die 152, a bending die 153 and a cutting blanking die 154 used in conjunction with the upper mold 14. A stamping space 16 is formed between the lower mold 15 and the upper mold 14. The lower mold 15 is provided with a plurality of accommodating cavities and a plurality of limiting assemblies (not shown in the figure). A spring plunger 158 for material withdrawal is provided in the accommodating cavity. When working normally, the spring plunger 158 is always in close contact with the lower side of the material strip 2. The limiting assemblies are distributed around the stamping space 16 and are used to limit the material strip 2 from multiple directions.

[0066] A cutting station is formed between the cutting insert 141 and the cutting blanking die 151, a reinforcing rib station is formed between the reinforcing rib insert 142 and the reinforcing rib concave die 152, a bending station is formed between the bending insert 143 and the bending concave die 153, and a cutting station is formed between the cutting insert 144 and the cutting blanking die 154;

[0067] During the stamping process, the upper die 14 will pass through the through hole on the press plate 12 to perform a stamping operation on the material strip 2, wherein the through hole can serve as a positioning hole for the upper die 14, thereby ensuring that the upper die 14 can be accurately positioned during stamping without position deviation. At the same time, this through hole can also enhance the rigidity of the upper die 14, which helps to increase the service life of the die.

[0068] The spring plunger 158 is composed of a plunger body and a spring, and its working principle is mainly based on the compression and release of the spring. A spring plunger 158 is installed at each workstation to provide uniform support force for the material strip 2. During the stamping process, the material strip 2 is always close to the lower side of the material strip 2, and with the support of the spring plunger 158, it is not easy to deform or bend, thereby maintaining the flatness of the material strip 2. When the upper mold 14 descends and starts the stamping operation, the stamping force will gradually increase and exceed the elastic force of the spring plunger 158. At this time, the spring plunger 158 will be pressed into its accommodating cavity, causing the spring to be compressed; after the stamping is completed, the upper mold 14 is reset to remove the stamping pressure on the material strip 2. As the upper mold 14 is reset, the spring plunger 158 begins to return to its original position due to the rebound force of its spring, and releases the energy stored during compression, pushing the material strip 2 to lift up slightly, so that the material strip 2 is separated from the action surface of the lower mold 15, thereby completing the material return. The material return is not a single action, but is coordinated with multiple stamping actions of the mold. While the material strip 2 is being lifted, the material strip 2 will continue to pass through various processes.

[0069] S2, setting of processing parameters: In this embodiment, it is intended to process an aluminum strip 2 with a thickness of 3.0 mm into an automobile heater heat exchanger with a reinforcing rib accessory 3 with a length of 141 mm. The processing parameters of the stamping equipment 1 and the feeder 44 are preliminarily set according to the material properties and process requirements of the strip 2. The processing parameters include the feeding speed v of the feeder 4, the punching force F' of the upper die 14, and the punching depth L';

[0070] S3: Install sensors: Several optical sensors (not shown) and piezoresistive flexible sensors (not shown) electrically connected to the control assembly are installed on each station. The optical sensors are used to monitor the position deviation of the material strip 2 at each station. The piezoresistive flexible sensors monitor the pressure distribution of the material strip 2 at each station by monitoring the change of the resistance value.

[0071] The optical sensor uses the principle of light reflection and refraction. When the material strip 2 passes through the monitoring area of ​​the optical sensor, the material strip 2 will block part of the light beam or change the reflection path of the light beam. The optical sensor can quickly capture these changes and convert them into electrical signals for subsequent processing and analysis. By monitoring the position and intensity changes of the light beam, the optical sensor can accurately determine the position deviation of the material strip 2 at each workstation to ensure the accuracy and stability of the processing process. The piezoresistive flexible sensor uses the piezoresistive effect, that is, when the piezoresistive flexible sensor is subjected to pressure, its resistance value will change, and the pressure distribution is measured by monitoring the change in resistance value.

[0072] In this embodiment, the piezoresistive flexible sensor is installed on the spring plunger 158 to monitor the pressure of the spring plunger 158 in real time. By analyzing whether the force of each spring plunger 158 is uniform, the flatness of the material strip 2 can be judged. Under normal circumstances, the spring plunger 158 should be uniformly subjected to the pressure from the material strip 2. If a part of the material strip 2 is uneven or warped, the force of the spring plunger 158 at these positions will be abnormal, which is manifested as too high or too low pressure. If the pressure of some spring plungers 158 is too high, it may mean that the height of the material strip 2 in this part is high or warped, and the bearing force cannot be uniform. Through the monitoring of the sensor, this unevenness can be identified in real time, and then the production process can be adjusted or an alarm prompt can be provided; if the pressure of some spring plungers 158 is low, it may be that the material strip 2 is in a loose or concave state in these areas, resulting in the spring plunger 158 not being able to obtain sufficient support force.

[0073] The sensor can not only monitor the flatness of the material strip 2 in real time, but also monitor the working status of the spring plunger 158. As the spring is used for a longer time, it may age or fatigue, resulting in reduced elasticity. The spring plunger fails to effectively lift the material strip 2 from the lower mold, which may cause incomplete material withdrawal or jamming. This problem can be discovered in time through the pressure changes monitored by the sensor. If the sensor detects that the pressure on some spring plungers 158 is relatively small for a long time, it may be because the spring has lost its elasticity, resulting in it being unable to effectively provide sufficient support. At this time, the control component issues an incomplete material withdrawal fault, reminding the operator to check whether the spring needs to be replaced or adjusted.

[0074] By combining the real-time data of the piezoresistive flexible sensor, comprehensive fault diagnosis and alarm can be achieved. When the pressure of multiple spring plungers 158 is low or uneven, the control system can analyze the possible faults and trigger corresponding alarm prompts or automatic adjustments; if the pressure of multiple spring plungers 158 is low, it may be due to the overall aging of the spring, resulting in the inability to effectively support the strip 2; if the pressure of some spring plungers 158 is too high, it may be due to unreasonable mold design, excessive thickness of the strip 2, or improper setting of certain process parameters. Through real-time data monitoring, the system can make dynamic adjustments during the production process to improve production efficiency and product quality.

[0075] S4, processing flow execution: placing the material strip 2 between the lower mold 15 and the pressing plate 12, starting the feeder 4 to move the material strip 2 to the position of the next process after the previous process is completed, until all processes are completed;

[0076] S5. Processing position control: The optical sensor and the mechanical sensor monitor the position deviation and pressure distribution of the material strip 2 in real time during the whole processing process, and feed the monitoring data back to the control component, which analyzes the data and makes corresponding adjustment measures;

[0077] S6. Processing quality control: The upper mold 14 is equipped with a load sensor and a displacement sensor electrically connected to the control component to monitor in real time whether the punching force F' and the punching depth L' of the upper mold 14 meet the design requirements during each processing, and feed back the monitoring data to the control component, which analyzes the data to determine the difference and makes corresponding adjustment measures;

[0078] S7, finished product inspection: Check the size, shape and surface quality of each accessory 3 to ensure that it meets the design standards;

[0079] S8. Processing parameter optimization: The control component adjusts and optimizes the processing parameters according to the processing parameters, monitoring results and adjustment measures of each process, and builds a mechanism for continuous improvement.

[0080] As a preferred embodiment of the present invention, the lower mold 15 also includes a guide mold 157 and a discharge mold 155. The guide mold 157 is arranged at the input end of the cutting and blanking mold 151, and is used to guide the material strip 2 conveyed by the feeder 4 to the cutting and blanking mold 151 for cutting processing. The discharge mold 155 is arranged at the output end of the cutting and blanking mold 154. The output end of the discharge mold 155 is provided with an elastic plate 156. The guide mold 157 is provided with a guide groove whose width matches the width of the material strip 2, and the inner wall of the guide groove fits the material strip 2. The input end of the guide mold 157 is provided with a guide angle, and the discharge mold 155 is a slope groove structure, and the groove wall of the slope groove is used to constrain the horizontal position of the accessory 3.

[0081] The elastic plate 156 at the output end of the material discharging die 155 can buffer the output of the accessory 3, provide a certain elastic support, ensure that the accessory 3 lands smoothly, avoid damage, and make the accessory 3 slide smoothly into the collection frame. The guide groove ensures that the material strip 2 can enter the mold accurately during stamping production, maintains the consistency of the position of the material strip 2 during the stamping process, and the inner wall of the guide groove fits the material strip 2, and its width matches the width of the material strip 2, which can effectively guide the material strip 2 to move along the predetermined path. The guide angle at the input end of the material guide die 157 helps to correct any deviation of the material strip 2 during the transmission process, allowing the material strip 2 to be corrected when it deviates, ensuring that the material strip 2 remains in the correct position during the entire stamping process. This design not only realizes automatic feeding, but also ensures that the material strip 2 is flat and has no twisting. Through the synergistic effect of the guide groove and the guide angle, the unnecessary impact and wear of the material strip 2 on the mold can be significantly reduced, and the service life of the mold can be extended. At the same time, precise guidance and limiting reduce the frequency of manual adjustment of the material strip 2, reduce labor costs, and improve the automation and production efficiency of the production line. The design of the slope groove helps to guide the accessory 3 to slide out smoothly, reducing jamming and blockage. The slope groove ensures that the accessory 3 maintains the correct direction and position during the discharging process, so that the accessory 3 can be discharged in an orderly manner and the scattering and confusion of the accessory 3 can be reduced.

[0082] As a preferred embodiment of the present invention, the optical sensor is installed on the lower surface of the first fixed plate 11, and the light beam emitted by the optical sensor passes through the pressing plate 12 to monitor the position of the material strip 2. The piezoresistive flexible sensor is installed on the spring plunger 158, and at least two spring plungers 158 are arranged on each workstation.

[0083] The optical sensor in this embodiment uses laser as a light source to accurately project a light beam in the processing area. The monitoring frequency of the optical sensor is 10Hz, and it is equipped with a high-speed camera to detect and record any changes in the light beam in real time. The optical sensor is set on the lower surface of the first fixed plate 11 and is close to the lower mold 15. It can ensure that the light beam emitted by the optical sensor can penetrate the pressing plate 12 through the through hole unimpeded, vertically or nearly vertically, and directly irradiate the surface of the material strip 2 to accurately monitor the position of the material strip 2; during the processing, the laser beam is accurately focused on the predetermined positioning point of the workpiece, and the system continuously tracks and monitors the real-time position of the light beam. Once the light beam is offset due to the movement, obstruction or other reasons of the material strip 2, the optical sensor will immediately capture this change and quickly feed back the relevant data to the control component. The control component has an advanced programmable logic controller (PLC) built in, which is responsible for processing and analyzing the data from the optical sensor. Based on this feedback information, the control component can automatically and accurately adjust the position of the material strip 2 to ensure that it always maintains the correct processing position. On the other hand, the piezoresistive flexible sensor is installed on the spring plunger 158, and its main task is to monitor and receive the pressure distribution from the lower surface of the material strip 2. By analyzing these pressure data, the flatness of the material strip 2 can be effectively evaluated.

[0084] As a preferred embodiment of the present invention, the first fixing plate 11, the second fixing plate 13, the upper die 14, the lower die 15 and the pressing plate 12 are made of high-strength alloy steel or aluminum alloy material.

[0085] In the design of the stamping equipment 1, the first fixed plate 11 and the second fixed plate 13 constitute the main supporting structure of the mold, and their main responsibility is to bear the pressure and load generated by the upper mold 14, the lower mold 15 and the pressure plate 12 during the stamping process. In order to ensure the stability and strength of the entire mold structure, the first fixed plate 11 and the second fixed plate 13 must be designed to be strong enough to withstand the various forces and stresses generated during the stamping process, and ensure that the upper mold 14 and the lower mold 15 will not be deformed or damaged during operation. The pressure plate 12 is located under the upper mold 14, and is in direct contact with the material strip 2 and applies pressure to fix the material strip 2 to prevent it from moving or shaking during the processing. Therefore, the pressure plate 12 needs to have sufficient strength to withstand the pressure and load during the processing. The upper mold 14 and the lower mold 15 are key components that directly bear high pressure and impact force during the processing, and need to have good strength and rigidity to ensure that they will not be damaged under high pressure and impact loads. In order to meet the requirements for strength and stability, the first fixing plate 11, the second fixing plate 13, the upper mold 14, the lower mold 15 and the pressing plate 12 are usually made of high-performance materials such as high-strength alloy steel or aluminum alloy. These materials not only have excellent strength and rigidity, can withstand high-intensity pressure and impact, but also have good wear resistance and corrosion resistance, which helps to extend the service life of the mold and maintain its long-term accuracy and performance, reducing the frequency of maintenance and replacement.

[0086] As a preferred embodiment of the present invention, the execution of the process in step S4 includes the following steps:

[0087] S401, cutting process: when the material strip 2 is transferred to the cutting station, the driving assembly controls the first fixed plate 11 to move downward, and drives the pressing plate 12 to press the upper surface of the material strip 2, and the first fixed plate 11 continues to move downward and drives the cutting insert 141 to pass through the through hole of the pressing plate 12, so as to perform cutting processing on the material strip 2;

[0088] S402, punching reinforcement rib process: after the incision process is completed, the material strip 2 moves to the reinforcement rib station, and the reinforcement rib insert 142 punches the material strip 2 downward to form a raised reinforcement rib on the lower surface of the material strip 2;

[0089] S403, bending process: the material strip 2 is moved to the bending station, the position of the material strip 2 is limited by the bending die 153 and the limit assembly, and the bending insert 143 is pressed downward to bend the two side edges of the material strip 2 into a preset angle, thereby completing the bending process;

[0090] S404, cutting process: under the limiting action of the bending die 153 and the limiting assembly, the cutting insert 144 punches the cut of the material strip 2 to complete the processing of a single accessory 3;

[0091] S405, material withdrawal: after all processes are completed, the upper mold 14 returns to the initial position, and the material strip 2 is withdrawn under the action of the spring plunger 158;

[0092] The stamping working principle of the stamping equipment 1 of the present invention is as follows: the driving component controls the first fixed plate 11 to move up and down under the instruction of the control component to ensure that the upper mold 14 can accurately cooperate with the lower mold 15. As the first fixed plate 11 descends, the functional components of the upper mold 14: the cutting insert 141, the reinforcing rib insert 142, the bending insert 143 and the cutting insert 144 will respectively cooperate closely with the corresponding modules of the lower mold 15: the cutting blanking die 151, the reinforcing rib concave die 152, the bending concave die 153, and the cutting blanking die 154. In the stamping space 16, the material strip 2 is limited in multiple directions by the limiting component to ensure the stability and accuracy of the stamping process. As the upper mold 14 continues to descend, the material strip 2 will be subjected to corresponding stamping effects at each station, such as cutting, reinforcing rib forming, bending and cutting. The spring plunger 158 can help withdraw the material after the stamping is completed to ensure that the material strip 2 can be smoothly removed from the mold. When a complete stamping cycle is completed, the drive assembly will start again, driving the first fixed plate 11 to rise, so that the upper die 14 is separated from the lower die 15, and prepare for the next stamping cycle. Stamping equipment 1 The equipment is equipped with a variety of die inserts, which can complete various stamping processes such as cutting, rib forming, bending and cutting, and realizes multi-functional integration. By replacing different die inserts, the equipment can easily adapt to the production needs of different products and has high flexibility.

[0093] As a preferred embodiment of the present invention, the adjustment measures in step S5 are specifically:

[0094] Position deviation adjustment: when the deviation of any position of the material strip 2 is ≤±0.5mm or less, no adjustment is required, and the current position of the material strip 2 and feeding speed are maintained; when the deviation of any position of the material strip 2 is less than ±0.5mm and less than ±1.0mm, the control component automatically adjusts the discharge amount of the feeder 4 to fine-tune the position of the material strip 2, and issues a position deviation alarm to prompt the operator to conduct on-site confirmation; when the deviation of any position of the material strip 2 is less than ±1.0mm, the processing is stopped, and a serious deviation alarm is issued to prompt the operator to conduct a thorough inspection and manual adjustment;

[0095] Pressure distribution adjustment: When the pressure distribution deviation is ≤±5% of the preset value, no adjustment is required, the current operating state is maintained, and production continues; when the pressure distribution deviation is less than the ±5% preset value and less than the ±10% preset value, the control component increases the punching force F' of the upper mold 14, and issues a position deviation alarm to prompt the operator to conduct on-site confirmation; when the ±10% preset value is less than the pressure distribution deviation, processing is stopped, and a serious deviation alarm is issued to prompt the operator to conduct a thorough inspection and manual adjustment.

[0096] As a preferred embodiment of the present invention, the design requirements of the punching force F' and the punching depth L' of the upper die 14 in step S6 are specifically as follows:

[0097] F'<F' min Or L'<L' min or k'<k' min , it is judged that the stamping is insufficient, the control component stops responding and sends out an alarm signal to notify the operator to make corresponding adjustment measures; F' min ≤F'≤F' max And L' min ≤L'≤L' max And k' min ≤k'≤k' max , it is judged that the stamping is normal, the control component does not respond, and continues to the next stamping work; F'>F' max or L'>L' max or k'>k' max , it is judged as over-stamping, the control component stops responding and sends out an alarm signal to notify the operator to make corresponding adjustment measures; where k' is the ratio of the overall stamping depth L' to the overall stamping force F', F' min and F' max are the minimum and maximum values ​​of the overall punching force design range, L' min and L' max are the minimum and maximum values ​​of the overall stamping depth design range, k' min and k' max are the minimum and maximum values ​​of the ratio design range respectively;

[0098] Among them, the ratio k' is compared with the ratio design range to determine whether the stamping work meets the requirements. When the stamping equipment 1 works normally, the overall stamping force F' and the overall stamping depth L' of the upper die 14 satisfy the following relationship:

[0099]

[0100] Wherein, γ1, γ2, γ3 are adjustment coefficients, t is the thickness of the strip 2, and B is the yield strength of the strip 2.

[0101] like Figure 7 As shown, in this embodiment, an aluminum strip 2 with a thickness of 1.0 mm and a yield strength B of 200 MPa is processed into a car heater heat exchanger with a reinforcing rib accessory 3 with a length of 141 mm. According to the material properties and process requirements of the strip 2, the feeding speed v of the feeder 4 is preliminarily set to 4 m / s. The overall punching force F' and the overall punching depth L' of the upper mold 14 are monitored in real time by the first load sensor and the first displacement sensor, and the following relationship can be obtained between the two:

[0102]

[0103] In the formula, the adjustment coefficients γ1, γ2, and γ3 are 2.45, 7.87×10 -9 , 19.2;

[0104] According to the process requirements, when processing the aluminum strip 2 with a thickness of 1.0 mm and a yield strength B of 200 MPa, in order to ensure the processing quality, safety and consistency, the overall punching force design range is 195 kN to 196.5 kN, the overall punching depth design range is 3.51 mm to 3.68 mm, and the ratio design range is 0.01800 to 0.01873. That is, the process requirements are as follows:

[0105] 195kN≤F'≤196.5kN

[0106] 3.51mm≤L'≤3.68mm

[0107] 0.01800≤k≤0.01873

[0108] By monitoring and controlling the ratio k, it is possible to ensure that the force and displacement relationship during the stamping process remains within the expected range, thereby ensuring the quality and consistency of the stamped parts. This method helps prevent over-stamping or under-stamping and ensures the stability and reliability of the stamping process.

[0109] As a preferred embodiment of the present invention, step S6 also includes the step of adaptively controlling processing parameters, by arranging a graphics acquisition device at each workstation to capture the edge and contour of the material strip 2 in real time, and feeding back to the control component to calculate and process the actual thickness of the material strip 2. The control component dynamically adjusts the stamping force F' and the stamping depth L' of the upper mold 14 according to the actual thickness size data, the characteristics of the material strip 2 and the process requirements.

[0110] The graphics acquisition device can use a high-resolution camera or a dedicated image sensor to continuously capture images of the material strip 2 for complex image processing and analysis, identify the edges and contour shapes of the edges of the material strip 2, and then deduce the actual thickness of the material strip 2. The control component dynamically calculates the optimal upper mold 14 punching force F' and punching depth L' through an algorithm model to ensure the accuracy and stability of the stamping process, and makes precise adjustments based on the actual thickness and characteristics of the material strip 2, which significantly improves the dimensional accuracy and shape consistency of the stamped accessories 3, ensuring that each stamped accessory 3 meets or exceeds the preset quality standards, thereby enhancing the market competitiveness of the product and customer satisfaction.

[0111] As a preferred embodiment of the present invention, step S8 specifically includes the following steps:

[0112] S801, collecting stamping data of each process, the stamping data including feeding speed v, stamping force F' and stamping depth L' of the upper die 14, thickness and hardness of the material strip 2, monitoring results and adjustment measures of the control components;

[0113] S802, simulation: using machine learning algorithms to analyze and simulate the collected stamping data, and establish a prediction model based on the stamping data;

[0114] S803, calculating the abnormality probability: predicting the workpiece state during the stamping process through the prediction model and calculating the abnormality probability of the accessory 3, the working state includes the shape, size and processing quality of the material strip 2;

[0115] S804, processing parameter optimization: the control component automatically adjusts the processing parameters according to the abnormal probability of accessory 3.

[0116] As a preferred embodiment of the present invention, the feeder 4 completes the conveyance of the material belt 2 through the driving wheel 41 and the driven wheel 42 arranged at the output port, and the material belt 2 is placed between the driving wheel 41 and the driven wheel 42. The driving wheel 41 and the driven wheel 42 are both provided with Hall sensors (not shown in the figure) electrically connected to the control component, which are used to monitor the rotation speed v1 of the driving wheel 41 and the rotation speed v2 of the driven wheel 42 respectively;

[0117] When |v1-v2|≤v3, it means that the feeding is normal and the control component does not respond;

[0118] When v1-v2>v3, it indicates that the material strip 2 is stuck during the stamping process, and the control component responds by stopping the machine and prompting the operator to replace the spring plunger 158;

[0119] When v1-v2<v3, the material strip 2 slips during the stamping process, the control component responds by stopping the machine, and prompts the operator that the material strip 2 has been transferred to the end, and replaces the new material strip 2 in time;

[0120] Among them, v3 is the speed deviation threshold, the unit is rad / s, and it satisfies the following relationship:

[0121]

[0122] Wherein, r is the radius of the driving wheel, b is the acceptable length error of a single accessory, in mm, and s is the moving rhythm of the material strip, in s.

[0123] In one embodiment, the radius of the driving wheel 41 is 30 mm, the length of a single component is 141 mm, and the moving beat of the material belt 2 is 3 seconds per component length. Therefore, under normal working conditions, the speed of the driving wheel 41 should be 1.57 rad / s. Since the acceptable length error of a single component in the design requirement is 3‰, that is, 3 mm, the speed deviation threshold v3 is 0.03 rad / s.

[0124] The feeder 4 drives the driving wheel 41 to rotate at a preset speed. The driving wheel 41 drives the material belt 2 to move forward while rotating. Since the driving wheel 41 and the driven wheel 42 are always in close contact with the material belt 2, the material belt 2 will also drive the driven wheel 42 to rotate when it moves. In this state, the friction force of the driving wheel 41 and the driven wheel 42 on the material belt 2 remains unchanged, and the rotation speeds of the two are the same.

[0125] When v1-v2>v3, it indicates that the material strip 2 is stuck during the stamping process, and the spring plunger 158 needs to be replaced. This is because the function of the spring plunger 158 is to provide a smooth and uniform material withdrawal support force for the material strip 2 so that it can smoothly leave the stamping die. However, when the spring plunger 158 ages and cannot provide sufficient material withdrawal support force, the material strip 2 will be stuck and cannot be smoothly transmitted. In this case, the driving wheel 41 continues to rotate, while the driven wheel 42 rotates slowly because the material strip cannot move normally, resulting in the speed v2 of the driven wheel 42 being less than the speed v1 of the driving wheel 41. This speed difference is greater than a set threshold value v3, which will cause the upper die to repeatedly stamp different positions of an accessory multiple times during the stamping process, seriously affecting the quality of the product.

[0126] When v1-v2<v3, it means that the material belt 2 slips during the stamping process and needs to be replaced with a new one. This is because when the material belt 2 is rolled to the end, the turning radius of the end of the roll is too small, and a large tension will accumulate inside the material belt 2, causing the thrust on the material belt 2 to increase. When this thrust exceeds the friction between the driving wheel and the driven wheel, the material belt slips, causing the speed v2 of the driven wheel 42 to exceed the speed v of the driving wheel 41. 11 If the speed difference is greater than a set threshold value v3, the material strip will move forward a long distance in each beat during the stamping process, making it impossible to align each processed part with the mold of each process.

[0127] It should be understood that the above-mentioned embodiments are one or more embodiments of the present invention, and there are many other embodiments and variations thereof based on the present invention; the variations and modifications made by ordinary technicians in this industry through the present invention without making pioneering innovations all fall within the scope of protection of the present invention.
