Sheet Metal Fabrication Bending Stamping Works Box Enclosure Processing Parts

As a special metal stamping part in stamping processing, drawing parts have different shapes, specifications and types. According to the characteristics of deformation mechanics, they can be divided into: box-shaped parts (straight-walled non-rotating body), round simple parts (refers to 4 types: straight wall rotating body), surface shape parts (referring to surface rotating body) and non-rotating body surface shape parts

1. Deformation characteristics of cylindrical parts

In the process of deep drawing, the deformation area is the flange edge part of the blank, 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 deformation area of ​​the blank produces tangential compression and radial The elongation is always in tension and always in compression; the ultimate deformation parameters are mainly limited by the load-bearing capacity of the force-transmitting area of ​​the blank.

2. Deformation characteristics of box-shaped parts

The deformation properties are the same as those of the round simple parts, the difference is that the deformation that is always under tension and always under compression is unevenly distributed on the periphery of the blank, the deformation of the rounded part is large, and the deformation of the straight edge part is small; on the periphery of the blank, the degree of deformation is greater than that of the blank. There is mutual influence between the parts with small deformation degree.

3. Deformation characteristics of curved surface parts

The outer circumference of the blank is a deep drawing deformation zone that is always in tension and is always compressed; the middle part of the blank is a bulging deformation zone affected by two-way tensile stress.

4. Deformation characteristics of non-rotational surface shape parts

The deformation zone of the deep-drawing blank is also composed of the external deep-drawing deformation zone and the internal bulging deformation zone, but the distribution of these two deformations on the periphery of the blank is uneven; There is also shear deformation in the outer peripheral deformation area of ​​the blank.
