|
|
This paper deals with the analysis of deformation tendencies on drawing plate with hole and offers a corresponding technological procedure as well as the quantitaive calculation formulas. Also, a computer block diagram has been provided in accordance with various lubrication conditions in production. Through running the software concerned and experimental research, it is proved that the technological procedure and formulas presented in this paper may solve various problems for drawing the plate with hole both in production and in products design procedure.
