Determination of Load and Strain-Stress Distributions in Hot Closed Die Forging Using the Plasticine Modeling Technique
An axisymmetric hot closed die-forging process has been studied by physical modeling technique using the plasticine. To observe the material flow pattern, layers of plasticine with different colors were used. The normal direction to the layers was considered a principal direction. The strain distribution was obtained by measuring the thickness of the plasticine layers. Based on the strain distr...
متن کاملOptimum Designing of Forging Preform Die for the H-shaped Parts Using Backward Deformation Method and Neural Networks Algorithm
In a closed die forging process, it is impossible to form complex shapes in one stage, and thus it becomes necessary to use preform dies. In the present study, Backward Deformation Method and FE simulation via ABAQUS software has been used in order to design preform die of the H-shaped parts. In the Backward Deformation Method, the final shape of the part is considered as a starting point and u...

متن کاملThe Review Study of Forging and Effects on the Produced Part
There are several method for forming bulk material, such as forging, rolling and extrusion. Every of these methods have advantages and dis-advantages of their selves. Forging process is one of the most common of them that include a die, press and in some case heater with controlling system, and has a special place in automotive, military and aerospace industries due uniformity of the final prod...
متن کاملDifferent methods of forging; applications and obstacles
Forging is a manufacturing process that consists of shaping the metal using localized compression forces. The blows are delivered with a hammer (often an electric hammer) or a die. In this paper, different methods of forging (multi-directional forging, hot forging, near-beta forging, multi-axial forging, direct powder forging, warm forging and ring forging) are discussed. The main problems that...
