Modelling And Optimization Of The Tool Geometry For Deep Drawing Of Sheet Metal

By means of modelling of the deep drawing process of axis-symmetric workpiece a mathematical model of drawing force process, has been defined the optimal range of roundness radius of the die, the optimal range of degree of strain and the optimal technological lubricator. The mathematical models, which show dependency of deep drawing force and the parameters of drawing process, the geometry of tool and the tribological conditions of the plastic forming, were estimated by regression analysis. The results of performed research indicate that the mathematical-experimental modelling can be successfully used to define the form of the tool work zone, the parameters of tribological processes and the technological parameters of the deep drawing process.
