| Summary: | The work analyzes the process of bending the sheet work piece to obtain shaping
of sheet metal parts and profiles. The analysis is carried out on the basis of strength
calculations of elastoplastic bending of the metal plate. When pressing such a plate,
in practice, a spring effect is observed when the curved blank changes its shape
under the influence of residual elastic deformations at the end of the pressing
process. To compensate for the spring effect, it is necessary to determine the
values of elastic and plastic deformations in the sheet blank. The work considers the
method of calculation of these values on the basis of available experimental works.
Conclusions have been drawn and practical recommendations can be used in the
process of setting process parameters for pressing sheet blanks. |
