THE FORCE OF DEEP DRAWING

The term metal forming refers to a group of manufacturing methods by which the given shape of a workpiece (a solid body) is converted to another shape without change in the mass or composition of the material of the workpiece. In this paper, the basics of a deep drawing process for the production of a thick plate steam boiler end caps are shown. Also the analysis of stresses which appear in the deep drawing process are shown – bending stress, frictional stress and inner stress due to displacement of material are also shown. Afterwards some mathematical formulations are made in order to find total stresses which appear in the material during the forming process which are needed for the force calculation.
