Production single parts from sheet metal

Project elaborate in terms of engineering studies branch 2303T002 submits proposal technology of production single parts from deep drawing press steel metal plate 11 305.21. On the basis literary study problems blanking, deep drawing and calculations was designed drawing in instrument with holder, to extrusion components serves lower ejector. Combination tool is set on hydraulic press CTH 250 with nominal tensile by force 250 kN. Drawable tools (drawing punch, drawing die) and shear pin tools (blanking punch, blanking die) are made from instrumental steels 19 436.3, heat treated condition to drawing documentation
