摘要

In this paper, a research about the influence of theudposition of a previously derived hole in the initial materialudintended for drawing onto the drawing workability of the coldudrolled metal sheets is made. This influence is researched byudhydraulic drawing of round steel sheets with previously derivedudholes on them. The research was made by drilling equal holes inudthe center of the metal sheet plate and displaced from the center,udbut placed in the main directions of the normal planar anisotropyudof the metal sheet. The goal is to proof that by changing theudposition of the previous derived holes the processing of the coldudrolled sheets can be improved and that will help to solveudtechnological problems in the production when the method ofuddrawing pieces with previously derived holes in the initialudmaterial is used.
