Description

Technical Field

[0001] The invention relates to the technical field of automobile production and processing, and in particular to a left and right swing arm bracket reinforcement plate stamping system and a control method. Background Art

[0002] In the field of automobile manufacturing, the swing arm bracket is one of the important components connecting the wheels and the body. Its strength and stability directly affect the driving safety and handling performance of the vehicle. The design of the left and right swing arm brackets must not only take into account the various forces generated by the vehicle during driving, but also ensure reliability and durability under various road conditions. In order to improve the mechanical properties of the swing arm bracket, reinforcement plates are usually added to its key parts to increase its bending resistance and torsional rigidity. The design and manufacturing process of the reinforcement plate directly affect the overall performance of the swing arm bracket, especially its performance under extreme conditions.

[0003] The left and right swing arm brackets in the automobile suspension system are important components to ensure the vehicle's driving stability and handling. In order to improve the strength and durability of the swing arm bracket, reinforcement plates are usually installed at its key positions. These reinforcement plates can not only improve the overall rigidity of the swing arm bracket, but also effectively disperse stress and extend its service life. The design and manufacture of reinforcement plates need to comprehensively consider factors such as material properties, processing technology, and the final application environment.

[0004] The reinforcement plate is mainly produced by stamping process. In recent years, there are many schemes for the stamping process design and die structure design of the left and right swing arm bracket reinforcement plate. The quality and precision of the stamped parts stamped by each stamping system are different, the material utilization rate is also different, and the life of the die is also different. The existing left and right swing arm bracket reinforcement plate stamping system has the disadvantages of unreasonable process design, complex die structure, multiple die processes, poor quality of stamped parts, and low precision. Summary of the invention

[0005] The invention aims to solve the technical problems that the punching system of the left and right swing arm bracket reinforcement plates in the prior art has unreasonable process design, complex mold structure, multiple mold processes, poor quality of stamped parts and low precision.

[0006] The present invention provides a left and right swing arm bracket reinforcement plate stamping system and control method. One of the left and right swing arm bracket reinforcement plate stamping systems includes a mold base plate, an upper mold assembly and a lower mold assembly. A stamping mold is arranged between the upper mold assembly and the lower mold assembly according to the stamping process. An electric cylinder is arranged on the top of the upper mold plate. It is characterized in that: it includes a control module, the control module is used to control the stamping process of the left and right swing arm bracket reinforcement plates, including an online acquisition unit, a programmable controller, a host computer and a human-computer interaction device; the online acquisition unit is used to detect the thickness and pressure of the left and right swing arm bracket reinforcement plates, including a pressure sensor and a displacement sensor arranged on the lower mold assembly; the programmable controller is electrically connected to the online acquisition unit, and the electric cylinder is connected to a control circuit, and the programmable controller is electrically connected to the online acquisition unit, and the electric cylinder is connected to a control circuit. The programmable controller is connected to the control circuit. When the control circuit detects that the electric cylinder is pressed down, it sends out a pressure trigger signal. The programmable controller is used to receive and process the weak current signal output by the online acquisition unit, receive the pressure trigger signal, analyze the weak current signal output by the online acquisition unit, and has an alarm output function for abnormal data; the host computer, including the configuration software, is connected to the programmable controller and is used for centralized monitoring, status display, SQL database creation, data storage and management of the left and right swing arm bracket reinforcement plate forming process; the human-computer interaction device is connected to the host computer, and is used for users to accurately trace, view in real time, operate and manage the left and right swing arm bracket reinforcement plate forming information.

[0007] A control method for a left and right swing arm bracket reinforcement plate stamping system specifically comprises the following steps: Step 1, before the production of the left and right swing arm bracket reinforcement plates, the upper computer configuration software operation system starts running, and the user sets the production and design information of the left and right swing arm bracket reinforcement plates online through the human-computer interaction device. The production and design information includes product code, size, production machine position, molding pressure F', left and right swing arm bracket reinforcement plate thickness T', comparison thickness △T', allowable deviation range of pressure and thickness δF' and δT', duration t of applied pressure, and adds records to the "Product Catalog Table". At the same time, the system automatically creates a "Production Data Record Table" belonging to the product to ensure that each left and right swing arm bracket reinforcement plate has a unique production data record table for real-time viewing and tracing of the production process status of the left and right swing arm bracket reinforcement plates; Step 2: The online acquisition unit collects the thickness and pressure of the left and right swing arm bracket reinforcement plates in real time, and transmits the weak current detection signals of the thickness and pressure to the programmable controller through RS485 bus communication. The programmable controller processes the weak current detection signals and generates a completion signal of applying pressure. Step 3: The upper computer configuration software automatically inserts a production message into the "Production Data Record Table" of the left and right swing arm bracket reinforcement plates according to the completion signal of the pressure applied during the forming process of the left and right swing arm bracket reinforcement plates. The production message includes the start and end times of the current forming applied pressure, the pressure received by the left and right swing arm bracket reinforcement plates, the thickness of the left and right swing arm bracket reinforcement plates, the comparison thickness of the left and right swing arm bracket reinforcement plates, whether there is an alarm, and the number of times of applied pressure.

When the timing time t reaches the set pressure holding time t', record the current thickness T0, and T0 is the initial forming reference thickness. Step 2.2: Add raw materials between the stamping dies and apply pressure. The programmable logic controller collects the pressure application trigger signal and starts pressure holding timing t. The left and right swing arm bracket reinforcement plates start to be formed. When the real-time pressure value fluctuates within a range of less than 100 kg per second, record the current pressure holding timing time as t1. During the time period t1 ≤ t ≤ t', record the measured pressure Fij and thickness Tij. i is the current thickness of the left and right swing arm bracket reinforcement plates, and j is the number of times recorded for the i-th millimeter during the time period t1 ≤ t ≤ t'. When t = t', output the completion signal of this pressure application; when t < t' and the pressure application trigger signal has disappeared, output the abnormal end signal of this pressure application. Step 2.3: Calculate the current thickness Ti, comparison thickness △Ti, and the pressure Fi received by the left and right swing arm bracket reinforcement plates: ; ; ; where: j ≤ n, n ≥ 5, and n is the total number of current thickness data records; Step 2.4: Calculate the deviation amounts δT and δF of the actual comparison thickness and the pressure received by the left and right swing arm bracket reinforcement plates from the set process parameters: δT = |δTi - δT'|, δF = |Fi - F'|; where δT' refers to the comparison thickness and F' refers to the forming pressure. Step 2.5: Compare the actual deviation amounts δF and δT of the pressure and thickness with their allowable deviation amounts δF' and δT’. If it exceeds the range, the programmable logic controller automatically outputs an alarm signal to warn of the quality problems of the left and right swing arm bracket reinforcement plates. Step 2.6, the programmable controller transmits the production and design information of all left and right swing arm bracket reinforcement plates to the host computer configuration software in real time through bus communication; Step 2.7, when the actual left and right swing arm bracket reinforcement plate thickness Ti does not reach the set left and right swing arm bracket reinforcement plate T, the current thickness of the left and right swing arm bracket reinforcement plate i=i+1, and repeat steps 2.2~2.6; otherwise, the programmable controller outputs the left and right swing arm bracket reinforcement plate forming completion signal to the drive module and the host computer, and prepares for sampling.

[0021] By introducing the control module 4 and the programmable controller 42, precise control of the stamping process can be achieved, manual intervention can be reduced, and the entire process can be made more reasonable and standardized. The online acquisition unit 41 monitors the thickness and pressure parameters in the stamping process in real time to ensure that each step can be carried out according to the preset standards. Through automated control and data acquisition, unnecessary process steps can be reduced and the design of the mold can be simplified, thereby reducing production costs and improving production efficiency. The configuration software in the host computer 43 creates an SQL database to record the data of each stamping, which is convenient for subsequent analysis and process improvement. The PLC has an abnormal data alarm output function, which notifies the operator in time when deviations occur to prevent unqualified products from continuing to be produced, thereby improving production efficiency and product quality. In summary, the design of a left and right swing arm bracket reinforcement plate stamping system not only improves production efficiency, but also effectively solves the technical problems of unreasonable process design, complex mold structure, multiple mold processes, poor quality of stamped parts, and low precision in the existing left and right swing arm bracket reinforcement plate stamping system through real-time monitoring and data analysis.

[0022] The human-computer interaction device 44 is specifically a liquid crystal touch screen; the programmable controller 42 communicates with the displacement sensor 412 and the pressure sensor 411 through the 485 communication module, receives the pressure trigger signal output by the control circuit through the digital input module, and sends an alarm signal to the alarm terminal through the digital output module. The programmable controller 42 centrally processes and analyzes the weak current signal and pressure trigger signal output by the online acquisition unit 41, realizing the centralized processing, analysis, and abnormal warning of large batches of data.

[0023] Users are divided into general operators, production managers, and system administrators according to their authority levels; general operators can view the production status, production managers also have the authority to enter new product record information, and system administrators, in addition to all the above authorities, also have the authority to obtain database data and personnel management.

[0024] A control method for a left and right swing arm bracket reinforcement plate stamping system specifically comprises the following steps: Step 1, before the left and right swing arm bracket reinforcement plates are produced, the configuration software operation system of the upper computer 43 starts to run, and the user sets the production and design information of the left and right swing arm bracket reinforcement plates online through the human-computer interaction device 44. The production and design information includes product code, size, production machine position, molding pressure F', left and right swing arm bracket reinforcement plate thickness T', comparison thickness △T', allowable deviation range of pressure and thickness δF' and δT', duration t of applied pressure, and adds records to the "product catalog table". At the same time, the system automatically creates a "production data record table" belonging to the product to ensure that each left and right swing arm bracket reinforcement plate has a unique production data record table for real-time viewing and tracing the production process status of the left and right swing arm bracket reinforcement plates; Step 2, the online acquisition unit 41 collects the thickness and pressure of the left and right swing arm bracket reinforcement plates in real time, and transmits the weak current detection signals of the thickness and pressure to the programmable controller 42 through RS485 bus communication, and the programmable controller 42 processes the weak current detection signals and generates a completion signal of applying pressure; Step 3, the configuration software of the upper computer 43 automatically inserts a piece of production information into the "production data record table" of the left and right swing arm bracket reinforcement plates according to the completion signal of the pressure applied during the forming process of the left and right swing arm bracket reinforcement plates. The production information includes the start and end time of the current forming pressure application, the pressure exerted on the left and right swing arm bracket reinforcement plates, the thickness of the left and right swing arm bracket reinforcement plates, the comparative thickness of the left and right swing arm bracket reinforcement plates, whether there is an alarm and the number of times pressure is applied. At the same time, the forming status of the left and right swing arm bracket reinforcement plates on all running equipment can be displayed and queried in real time, providing users with the function of quickly tracing the production process and exporting information.

[0025] In some implementations, the specific process of processing and controlling by the programmable controller 42 is as follows: Step 2.1, before the forming of the left and right swing arm bracket reinforcement plates, apply pressure once without adding raw materials. The programmable logic controller 42 collects the pressure application trigger signal and starts timing from zero. When the timing time t reaches the set pressure holding time t', record the current thickness T0, and T0 is the initial forming reference thickness. Step 2.2, add raw materials between the stamping dies 3 and apply pressure. The programmable logic controller 42 collects the pressure application trigger signal and starts pressure holding timing t. The left and right swing arm bracket reinforcement plates start to be formed. When the real-time pressure value fluctuates within a range of less than 100 kg per second, record the current pressure holding timing time as t1. During the time period of t1 ≤ t ≤ t', record the measured pressure Fij and thickness Tij, where i is the current thickness of the left and right swing arm bracket reinforcement plates, and j is the number of times recorded for the i-th millimeter during the time period of t1 ≤ t ≤ t'. When t = t', output the signal indicating the completion of the current pressure application; when t < t' and the pressure application trigger signal has disappeared, output the signal indicating the abnormal end of the current pressure application. Step 2.3, calculate the current thickness Ti of the left and right swing arm bracket reinforcement plates, the thickness difference △Ti, and the pressure Fi applied to the left and right swing arm bracket reinforcement plates: ; ; ; where: j ≤ n, n ≥ 5, and n is the total number of times the current thickness data is recorded. Step 2.4, calculate the deviation amounts δT and δF of the actual thickness difference and the pressure applied to the left and right swing arm bracket reinforcement plates from the set process parameters: δT = |δTi - δT'|, δF = |Fi - F'|; where δT' refers to the thickness difference and F' refers to the forming pressure. Step 2.5, compare the actual deviation amounts δF and δT of the pressure and thickness with their allowable deviation amounts δF' and δT'. If it exceeds the range, the programmable logic controller 42 automatically outputs an alarm signal to warn of the quality problems of the left and right swing arm bracket reinforcement plates. Step 2.6, the programmable logic controller 42 transmits all the production and design information of the left and right swing arm bracket reinforcement plates to the configuration software of the host computer 43 in real time through bus communication. Step 2.7, when the actual thickness Ti of the left and right swing arm bracket reinforcement plates does not reach the set thickness T of the left and right swing arm bracket reinforcement plates, the current thickness i of the left and right swing arm bracket reinforcement plates is incremented by 1, and repeat Steps 2.2 to 2.6; otherwise, the programmable logic controller 42 outputs a signal indicating the completion of the forming of the left and right swing arm bracket reinforcement plates to the drive module and the host computer 43, and prepares for the next sample.

[0026] In some embodiments, the programmable logic controller 42 contains a software program that can complete the above Steps 2.1 to 2.6.

The coordinated use of the guide column 25 and the guide sleeve 14 ensures the precise guidance of the upper die assembly 1 and the lower die assembly 2 when closing and opening, preventing the upper die assembly 1 and the lower die assembly 2 from being deflected during the stamping process, thereby ensuring the processing accuracy. The floating material guide block 24 is used to position the raw materials during the stamping process, ensuring that the raw materials are placed accurately and preventing the raw materials from being offset or twisted.
