Abstract

In this paper, research about the influence of the dimension to a hole derived in initial material processing with drawing the cold-rolled steel sheets is made. This influence is researched by hydraulic drawing to steel sheets with previos derived holes with diffrend dimensions. The area between 4.2-16.35 mm is researched and corrective factor of influence to the size of the previously derived circular hole in the initial material is defined. The goal is to proof that by changing the dimensions of the prevous derived holes the processing of the cold-rolled sheets can be improved and that will help to solve technological problems in the production when the method of drawing the cold-rolled sheets with previous derived holes in the initial material is used.
