The deep drawing coefficient, which is the ratio of the billet diameter D to the workpiece outer diameter d, is an important indicator for measuring the difficulty of deep drawing. The smaller the deep drawing coefficient, the greater the degree of deformation, and the easier it is for the billet to crack, often requiring multiple deep drawings to complete the forming of the workpiece.

The deep drawing die is mainly composed of a convex die, a concave die, and a edging ring. Under the action of the press, the convex mold gradually presses the circular billet into the concave mold, and its shape and size determine the inner surface shape of the workpiece after deep drawing. The concave die is the outer contour limitation of the blank deformation, and its inner wall shape is adapted to the outer surface of the deep drawn part.

Metal stamping offers several advantages, including high production efficiency, good product quality, strong adaptability, and low cost. The details are as follows: High Production Efficiency: Stamping processing is highly efficient. Ordinary presses can complete dozens of strokes per minute, while high-speed presses can reach hundreds or even thousands of strokes per minute, enabling the production of a large number of parts in a short time.

In practical production, deep drawing technology has a wide range of applications. For example, in the automotive manufacturing industry, the manufacturing of components such as engine oil pans and body coverings cannot be separated from deep drawing technology. Taking the engine oil pan as an example, its shape is complex and requires high dimensional accuracy and surface quality. During the manufacturing process,

Metal stampingis a manufacturing process that uses dies and presses to shape metal sheets into various forms. It has a wide range of applications in many industries. Some of the main applications are as follows:

Metal Stamping Forming A cold-forming process (also known as cold stamping or sheet metal stamping) that utilizes the force of stamping presses to directly shape metal sheets within dies. The resulting components are widely used in automotive parts and household appliance manufacturing.
