What are the types of processing shapes of stainless steel drawing parts?

Simply put, drawing is a stamping method in which a flat blank is formed into an open hollow part with a die. Thin-walled parts with irregular shapes such as cylindrical, rectangular, stepped, spherical, conical, and parabolic shapes can also be combined with other stamping processes to produce parts with more complex shapes.

According to the characteristics of deformation mechanics, stainless steel tensile parts can be divided into box-shaped parts (straight-wall non-rotating body), circular simple-shaped parts (straight-wall rotating body), surface-shaped parts (referring to curved surface rotating body) and non-rotating surface forming Components. It is characterized by:

First, the deformation characteristics of cylindrical parts.

In the deepening process, the deformation area is the blank flange edge, and the other parts are the force transmission area, which does not participate in the main deformation; under the action of tangential compressive stress and radial tensile stress, the blank deformation area produces tangential compression and radial tension. The deformation of the extension; the extreme deformation parameters are mainly limited by the bearing capacity of the blank force transmission area.

Second, the deformation characteristics of the box.

Its deformation properties are the same as for circular simplified parts. The difference is that the deformation that is always stretched and compressed is unevenly distributed around the blank, the rounded corners have large deformation, and the straight edge has small deformation; there is an interaction between large and small deformations around the blank.

3. Deformation characteristics of curved surface shape parts.

The periphery of the blank is the tensile deformation area that has been under compression, and the middle of the blank is the expansion deformation area of ​​bidirectional tensile stress.

4. Deformation characteristics of non-rotating body curved parts.

The deformation area of ​​deepening the blank is also composed of the outer deepening deformation area and the inner expansion deformation area, but the distribution of these two deformations around the blank is uneven; when the flange edge of the surface is partially deepened, the deformation area around the blank also has shearing deformed.

The above is the processing appearance type of stainless steel drawing parts. In the processing of drawing parts, quality is an important issue that cannot be ignored. No matter what type of drawn part, material, process and die are important factors that affect the deep drawing process. Hope the above content can be helpful to readers.
