As an important stamping process product, deep drawn parts have a series of significant characteristics. The following is a detailed introduction to the characteristics of deep drawn parts:
1. Material strength and surface smoothness: The deep drawn parts adopt a cold forming process to avoid the formation of pores in the material, thereby ensuring higher material strength. In addition, deep drawn parts have a smooth and uniform surface, and the workpiece has no pores, shrinkage holes, or scale marks, which makes its surface more beautiful and easy to clean.
2. Number and aesthetics of welds: In the manufacturing process of deep drawn parts, the geometric shape can be processed from the same piece of metal, instead of multiple metal blocks being formed separately and then welded, which greatly reduces the number of welds. When the aesthetics and smoothness of the workpiece are important, or when it needs to be easy to clean and disinfect, this characteristic is particularly evident, making it widely used in fields such as the pharmaceutical industry, food industry, and design industry.
3. Deformation characteristics: The deformation of deep drawn parts has specific patterns. During the deep drawing process, the deformation zone is mainly concentrated in the flange part of the blank, and the part in contact with the convex die end face is basically not deformed. Under the action of tangential compressive stress and radial tensile stress, the blank undergoes deformation under tangential compression and radial tension. The ultimate deformation parameters are mainly limited by the bearing capacity of the load transfer zone of the blank. In addition, there will be thickening at the mouth of the deep drawn part and thinning at the bottom corner, which is called a dangerous section.
4. Diversity in shape and size: Deep drawn parts have diverse geometric shapes and can be made into thin-walled parts with cylindrical, stepped, conical, hemispherical, square box, and other irregular shapes. If combined with other stamping processes, complex curved parts can also be manufactured to meet the needs of various complex shapes and sizes.
5. Widespread application: Due to the advantages mentioned above, deep drawn parts have a wide range of applications in various fields. Whether it is large-scale manufacturing industries such as automobiles and airplanes, or the production of daily necessities such as household appliances and furniture, deep drawn parts play an important role.
