ترجمة الملخص

Operations of sheet metal forming take up leading sites in the world of industry because almost note in each modern product, and in the forefront of these processes is the deep drawing process, which won the attention of researchers for a long time because of its importance and multiplicity of its applications, as, drawing of cups, the ammunition casings, cans, household and medical appliances, etc. The demand for high precision and reliability in the formed metal parts, and the reduction of waste resulting from trial and error method, which is still followed in this process, require predictability of painstaking values of the influencing factors in the deep drawing process, where the main problems observed in the deep drawing are wrinkling the drawing blank or torn it. In this research, deep drawing process of the optional piece has been simulated in order to predict the optimal factors of the process, geometric models for each of the blank, the die, the punch and the blank holder have been modeled by using a computer-aided design SolidWorks®, the program DEFORM™ was also used to simulate the drawing process by using finite element method. The simulation of drawing process in this research was carried out negligently temperature changes by applying various factors on studied blanks, the used materials in this study are Aluminum (AL_1100) and steel(1), which has structure and properties similar to the steel used in the tractors factory. The results of the simulation that have been discussed are: deformation of the metal during the drawing process, applying the holding force on the blank and influence of the coefficient of friction, changes in the thickness of the studied blanks. Coulomb friction model was used by various values for the coefficient of friction, and the effect of each of the blank holding force, the radius of the die roundness and blank metal has been studying. Finally a methodology has been proposed to evaluate the appropriate factors for deep drawing process based on comparisons between the experimental and numerical results.
