The design of left and right swing arm supports not only needs to consider bearing various forces generated during vehicle driving, but also needs to ensure reliability and durability under various road conditions. In order to improve the mechanical performance of swing arm supports, reinforcing plates are usually added at key positions to increase their bending resistance and torsional stiffness. The design and manufacturing process of reinforcing plates directly affect the overall performance of swing arm supports, especially their performance under extreme conditions.

[0003] The left and right swing arm supports in the automobile suspension system are important components that ensure the driving stability and handling performance of the vehicle. In order to improve the strength and durability of the swing arm supports, reinforcing plates are usually installed at key positions. These reinforcing plates not only improve the overall rigidity of the swing arm supports, but also effectively disperse stress and prolong service life. The design and manufacturing of reinforcing plates need to consider factors such as material performance, processing technology, and final application environment.

[0004] Reinforcing plates are mainly produced through stamping forming process. In recent years, there are many schemes for the design of left and right swing arm support reinforcing plate stamping process and die structure.

The programmable controller 42 centrally processes and analyzes the weak electric signal and the applied pressure trigger signal output by the online acquisition unit 41, realizes centralized processing, analysis and abnormal warning of a large amount of data.

[0036] According to the different authority levels, the users are divided into ordinary operators, production managers, and system administrators; the ordinary operators can view the production status, the production managers also have the permission to input new product record information, and the system administrators have all the above permissions and also have the permission to obtain database data and personnel management.

[0037] A control method of a left and right swing arm support plate stamping system, specifically comprising the following steps:

[0038] Step 1, before the production of the left and right swing arm support plate, the host computer 43 configuration software running system starts to run, and the user sets the production and design information of the left and right swing arm support plate online through the man-machine interactive device 44, the production and design information includes product code, size, production position, forming pressure F', thickness T' of the left and right swing arm support plate, contrast thickness AT', allowable deviation range of pressure and thickness δF' and δT', duration of pressure application t, and adds records to the "product catalog table", and the system automatically creates a "production data record table" belonging to the product, ensuring that each left and right swing arm support plate has a unique production data record table for real-time viewing and tracing of the production process state of the left and right swing arm support plate;

[0039] Step 2, the online acquisition unit 41 collects the thickness and pressure of the left and right swing arm support plate in real time, and transmits the weak current detection signals of the thickness and pressure to the programmable controller 42 through the RS485 bus communication, and the programmable controller 42 processes the weak current detection signals and generates a complete signal of the applied pressure;

[0040] Step 3, the host computer 43 configuration software automatically inserts a production information into the "production data record table" of the left and right swing arm support plate according to the complete signal of the applied pressure in the forming process of the left and right swing arm support plate, the production information includes the current forming applied pressure start and end time, the pressure of the left and right swing arm support plate, the thickness of the left and right swing arm support plate, the contrast thickness of the left and right swing arm support plate, whether there is an alarm and the number of applied pressure, and at the same time, the forming state of the left and right swing arm support plate on all running equipment can be displayed and inquired in real time, and the user can quickly trace the production process and information export function.

[0041] In some embodiments, the specific process handled and controlled by the programmable controller 42 is as follows:

[0042] Step 2.1, before the forming of the left and right swing arm support plate, a pressure application process is performed without adding raw materials, the programmable controller 42 collects the pressure application trigger signal and starts timing from zero, and when the timing time t reaches the set pressure duration t', the current thickness , and is the initial forming reference thickness;

[0043] Step 2.2, the raw materials are added between the punch dies 3, pressure is applied, the programmable controller 42 collects the pressure application trigger signal, starts the pressure holding timing t, and the left and right swing arm support reinforcement plates start to be formed. When the real-time pressure value fluctuates less than 100 kg per second, the current pressure holding timing is recorded as t1. During the time t1≤t≤t', the measured pressure Fij and thickness Tij are recorded, i is the current thickness of the left and right swing arm support reinforcement plate, and j is the number of times recorded within t1≤t≤t'. When t=t', the pressure application completion signal of this time is output; when t<t' and the pressure application trigger signal has disappeared, the pressure application abnormal end signal of this time is output.

[0044] Step 2.3, the thickness Ti of the current left and right swing arm support reinforcement plate, the comparison thickness △Ti, and the pressure Fi borne by the left and right swing arm support reinforcement plate are calculated.

[0045] ;

[0046] ;

[0047] ;

[0048] Wherein: j≤n, n≧5, n is the total number of current thickness data records;

[0049] Step 2.4, the deviation amount δT and δF of the actual left and right swing arm support reinforcement plate comparison thickness and the pressure from the set process parameters are calculated: δT=|△Ti-△T'|, δF=|Fi-F'|; wherein △T' refers to the comparison thickness, and F' refers to the forming pressure.

[0050] Step 2.5, the actual deviation amounts δF and δT of the pressure and thickness are compared with the allowable deviation amounts δF' and δT'. If the range is exceeded, the programmable controller 42 automatically outputs an alarm signal to warn of the quality problem of the left and right swing arm support reinforcement plate.

[0051] Step 2.6, the programmable controller 42 transmits all the production and design information of the left and right swing arm support reinforcement plate to the upper computer 43 configuration software in real time through bus communication.

[0052] Step 2.7, when the actual thickness Ti of the left and right swing arm support reinforcement plate does not reach the set thickness T of the left and right swing arm support reinforcement plate, the current thickness i of the left and right swing arm support reinforcement plate is i=i+1, and steps 2.2-2.6 are repeated. Otherwise, the programmable controller 42 outputs the left and right swing arm support reinforcement plate forming completion signal to the drive module and the upper computer 43, and prepares for sampling.

Step 2.5, compare the pressure, thickness actual deviation δF, δT and its allowable deviation δF', δT', if out of range, programmable controller automatically output alarm signal, early warning left and right swing arm support plate quality problems; Step 2.6, programmable controller will all left and right swing arm support plate production and design information through bus communication real-time transmission to the host computer configuration software; Step 2.7, when the actual left and right swing arm support plate thickness Ti does not reach the set left and right swing arm support plate T thickness, left and right swing arm support plate current thickness i = i + 1, repeat step 2.2~2.6; Otherwise, programmable controller to drive module and host computer output left and right swing arm support plate forming completion signal, ready for sampling.
