You will know how to build a car in four processes. The importance of Toyota manufacturing process development organization structure in GM manufacturing process department is self-evident. If there is no complete automobile manufacturing process, cars can't be built. Compare Toyota's production technology department to find out the complexity of automobile manufacturing process.
Stamping process design process stamping is the first step of all processes. The stamping process is to pull out the common steel, punch/cutting edge, and use the mold to drop out the specific workpiece of the vehicle.
Simplify the process of stamping process design. The input of stamping process is white car design. From the above simplified stamping process, it can be seen that the design and development of stamping process need stamping process review, stamping matching analysis, stamping process design confirmation, stamping equipment selection, die development and inspection. And it's a buckle ring. It's impossible. The quality of the die directly determines the quality of the workpiece, so the die is very important in the stamping process. And the cost of the new mold is very high.
The four basic processes in the stamping process are usually divided into four steps: stamping, bending, stretching and local forming. The purpose of hot stamping is to separate the paper, including hot stamping, descending, trimming and cutting steps. The purpose of bending is to make the paper reach a certain angle and shape along the bending curve. The purpose of stretching is to transform the flat plate into hollow parts with various openings, or to further change the shape and size of hollow members. The purpose of local forming is to change the blank or stamping, and its local deformation has different properties, including turning, unfolding, flattening and forming. Examples of common parts stamping process
Welding process design flow Welding process is the process of joining stamped body panels into the vehicle assembly by heating and pressurizing. The quality of welding directly affects the strength of the car body. When the physical strength is insufficient, the body may not be safe in the protective car. The welding process is also divided into three stages: welding process planning, welding process design and welding process verification. Each stage will undergo rigorous verification and simulation to ensure that the body assembly meets the design requirements. Welding process simplification is the most widely used process in automobile body manufacturing. Many manufacturers will emphasize "laser welding" when promoting. Most domestic manufacturers do manual welding, because the domestic labor cost is still lower than that of automatic equipment.
