Study on Edgetrimming of Holes in the Thick Steel Plates by Metal Plastic Forming Technology

Abstract:

In this paper the results of investigations carried out in the field of hole-flanging in thick steel sheets were presented. All experiments were performed in the Division of Metal Working of the Institute of Materials Technology at the Poznan University of Technology. An experiments of hole-flanging were carried out using cylindrical, spherical and conical punches. The blanks made of BW11, 34GHA and 15HGMV steels were investigated using different holes diameters. The holes were prepared using boring and laser techniques. The influence of the method of holes preparation on the quality and dimensions of obtained flanges were discussed.
