   The so-called processability of automotive stamping parts refers to the adaptability of automotive stamping parts to handicrafts, that is, whether the designed automotive stamping parts meet the process requirements of automotive stamping parts processing in terms of size, dimensional accuracy and benchmark, structural shape, etc. Automotive stamping parts should have good craftsmanship and economy, and important indicators to measure their level include the number of processes for automotive stamping parts, the number and size of body assembly blocks, and the structure of automotive stamping parts. Reducing the number of processes in the automotive stamping process means reducing the number of automotive stamping parts, saving the number of fixtures, simplifying the transmission device of the automotive stamping process, reducing the area occupied by operators and automotive stamping parts, which is an excellent measure to save investment and energy consumption. Therefore, automotive stamping parts manufacturers can design the number of processes in automotive stamping parts as an important way to reduce automotive manufacturing costs, Even willing to improve product design to meet manufacturing process requirements. At the same time, it is also necessary to use reasonable overall body components of the largest size possible, such as the left and right side panels and roof panels of the whole body, to ensure a beautiful appearance of the car. Reducing air resistance can also reduce the number of automotive stamping parts and welding points, effectively reducing costs. In addition, Hyundai Motor Company manufacturing uses a large number of high strength steel sheets and galvanized steel sheets with coiled materials and thin shell integral body structure, which require the application of new technology of automobile stamping parts. Process Technology for Automotive Stamping Parts

   (6) Automatic monitoring of the forming process of automotive stamping parts and analysis of instability mechanisms.

   Modular automotive stamping parts

   The outstanding advantage of modular automotive stamping parts is that they can organically combine the flexibility of automotive stamping parts processing systems with efficient production. The meaning of flexibility is broad, such as the various geometric requirements for automotive stamping parts, which can be obtained through free programming, reflecting the flexibility of machining shapes. For example, it is not only suitable for the production of large-scale single variety automotive stamping parts, but also has advantages in small batch and multi variety processing, demonstrating flexibility. In summary, the key points of modular automotive stamping parts are:

   (1) Quick replacement of combined molds during the forming process of automotive stamping parts to improve production efficiency

   (2) Due to the presence of strip feeding and straightening devices, additional loading and unloading processes can be avoided

   (3) Realized non-stop machining of large workpieces

   (4) Capable of both independent and serial control of combined die movements, capable of continuously processing automotive stamping parts

   (5) The stamping die has the flexibility of being programmable.

   The main reasons for changes in workpiece quality during the automotive stamping process include wear, cracks, and misalignment of the concave and convex stamping dies. These small changes can be tracked and detected by high-resolution displacement sensors and automotive stamping force sensors. Displacement measurement is an extremely important type of measurement, which is usually composed of a closed source installed above the mold and a receiving unit located below. It can monitor deviations, track the entire processing process, output monitoring information in a timely manner, and provide alarms and shutdowns.
