Automotive stamping products
Many cold stamping processes are used in the production of automotive stamping parts. This process not only has high production efficiency and stable product quality, but also is very suitable for the needs of the automotive industry for various types and mass production.
In medium- and heavy-duty cars, most of the covering parts such as the outer panel of the car body, and a few load-bearing and supporting parts such as the frame, the compartment and other parts are all stamped parts.
The steel used for cold stamping is mainly steel plates and steel strips, which account for 72.6% of the total vehicle steel consumption. The relationship between cold stamping materials and stamping production is very close. The quality of the materials not only determines the function of the product, but also directly affects the stamping The process design of the process affects the quality, cost, application life and production deployment of stamping products. Therefore, the fair selection of automotive stamping parts data is a major and confusing task.
In automobile stamping parts, a partial stamping part directly becomes a car part after being stamped, and the other part of the stamping part needs to be processed by welding, machining, or painting before it becomes a car part after being stamped.
Therefore, the selection of stamping materials must not only meet the requirements of product application functions, but also satisfy the requirements of stamping process and subsequent processing (such as welding, machining, etc.).
Stamping parts are mainly classified by process, which can be divided into two categories: distinguishing process and forming process.
The distinguishing process is also called blanking, and its purpose is to distinguish the stamping parts from the sheet along a certain contour line, and to ensure the quality requirements of distinguishing the section.
The purpose of the forming process of stamping parts is to make the sheet metal produce plastic deformation without breaking the blank, and make the workpiece with the required shape and specification.
In actual production, multiple process deductions are often used on one workpiece.
Blanking, zigzag, shearing, deep drawing, bulging, spinning and correction are just a few important stamping processes.
Standardization of mold bases, mold bases, and guides, and development of simple molds (for small batch production), compound molds, multi-station progressive molds (for many productions), and R&D rapid mold change and installation can reduce stamping production The amount of preparation work and shortening the preparation time can reduce the amount of preparation work and shorten the preparation time for stamping production, and enable the advanced stamping technology that is practical for mass production to be reasonably used in small batches of various types of production.
