The details of sheet metal stamping process.
First, the definition and principle of stamping
Stamping refers to the technology of machining sheet metal into the desired shape using tool die pressure such as a punch
or punching machine. In popular terms, it is to put a metal plate in a mold, and then press the board into the desired shape
and size. The stamping process can not only produce lightweight, strong and durable metal parts, but also greatly improve
production efficiency.
Second, the stamping process
The specific flow of the stamping process is as follows:
1. Develop design plan, including parts shape and size
2. Make molds
3. The metal sheet is deeply injected into the sheet metal mold
4. Force the sheet through the mold opening at high speed and high pressure to cut the sheet into the required shape
5. Use processing equipment to process the parts, such as punching holes, punching patterns, punching curves, etc.
6. Perform quality inspection to ensure that the parts meet the requirements.
Three, the common stamping process
1. Deep drawing stamping: Deep drawing stamping converts metal sheets into three-dimensional parts with deeper geometric shapes.
This process needs to be controlled by a deep drawing die, also known as stamping drawing.
2. Swing stamping: Swing stamping technology is used to manufacture highly complex parts, such as automotive contours.
This process needs to be controlled by an oscillating impact die, creating bends and bends in the geometry of the material.
3. Special-shaped stamping: special-shaped stamping technology is used to process parts with irregular curves or complex curves.
Special-shaped stamping usually requires the use of professional CNC machine tools, the accuracy is higher than the general stamping.
In short, stamping is an efficient and high-precision metal processing technology, which has been widely used in various
industries. Mastering the stamping process and technical essentials is very important for practitioners in the processing
and manufacturing industry.
