[0002] Metal casings, especially end caps for large drums, are widely used in the chemical, food, and pharmaceutical industries for storing and transporting liquid or solid materials. They are typically manufactured using a stamping process, where molds are used to plastically deform sheet metal to achieve the final shape.

[0003] In the traditional production process of large barrel end caps, the placement of the blanks mainly relies on manual operation. Operators need to manually place the metal sheet blanks into the designated positions on the mold to ensure that the dimensional accuracy and appearance quality of the stamped end caps meet the requirements. However, this manual positioning method has some problems. It is difficult to guarantee that the blanks can be accurately positioned every time, which can easily lead to deviations. This results in defects such as out-of-tolerance dimensions and irregular shapes in the stamped end caps, affecting the product qualification rate. Furthermore, manual operation is slow and it is difficult to maintain high-precision positioning for a long time, which restricts the improvement of production efficiency.

[0004] Therefore, a metal shell and its manufacturing stamping die are proposed. Utility Model Content
