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...

Some problems on setting up die-forging technological scheme design criteria by means of traditional methods are analyzed. The idea of mining die-forging technological schemes based on orthogonal plan is pointed out. The height and width of the hub are selected as key factors from many ones which influence the die-forging technological schemes of axisymmetric forging, then, in connection with t...

precision forging process is widely used for the production of spur gears due to its advantages such asimproved strength and surface finish, little waste of materials and reduction in the machining time ofthe gear. an important aspect of precision forging process is the load required to perform the processsuccessfully and design the forging tools. in this research, a new kinematically admissibl...

Technological processes such as forging, die forging, and pile driving are realized as a result of a collision between two bodies. After the impact the bodies’ energy transforms to plastic or elastic deformations of the colliding bodies. This paper studies both theoretically and experimentally the influence of impact parameters such as forces, accelerations, velocities, time and energy on defor...

An important aspect of precision forging process is the load required to perform the process successfully and design the forging tools. In this research, a new kinematically admiss...

The mandrel reaming forging is of great significance to the billeting ring ingot. Through analysis deformation steel ingot mandrel, it concluded that exists in radial, axial and tangential directions, which are similar rigid zone, active plastic zone passive upsetting theory. Numerical simulation methods used analyze verified has a an directions. At same time, reduction rate found greater impac...

In this essay, a combination of neural network and genetic algorithm has been studied for optimization of the preform in close die forging. Finite Volume Method (FVM) is used as a simulation tool for forging processes. The simulation results have used in the neural network and the genetic algorithm has been employed to optimize the forging force. The neural network was used in three stages for ...

Three important parameters in designing a closed die for forging process are ratio of width to flash thickness, ratio of  height to billet diameter and the friction factor. In this paper the influences of these parameters on the required force for the forging and percentage of die filling were investigated. It was found that by controlling the flash dimension, the material loss is reduced and t...
