This paper presents an approach for a holistic simulation of forging processes considering the interactions between forging press, tooling system and forging process. It can be used in coupled simulations and will enable industrial users in forging industry to do simulation-aided tool optimizations in the design stage of newly developed forging dies. The final aim is to reduce the time-consumin...

Regulation of residual stress in a component is the key to improving its service performance. A cold expansion method was proposed for reducing 7050 aluminium alloy curved frame forging after quenching. The effect on and equivalent plastic strain distribution investigated. results showed that maximum at center thickness reduced from 153 MPa 94 expansion, while it decreased 283 120 surface with ...

The purpose of this research is to achieve the optimal parameters for producing forged aluminium alloy 7075 aircraft door bracket by using finite element modelling (FEM) with commercial DEFORM-3D V6.1 and physical simulations with plasticine and Plexiglas dies. Also, forging speed has been examined as the main factor for controlling to produce a part without any defects. The results of Physical...

Preform design in forging processes is an important aspect for improving the forging quality and decreasing the production cost. The objective of this paper is to obtain an optimal perform shape in the consideration of the influence of the metal flow deformation in closed die forging process. Finite element method based DEFORMTM 3D software in conjunction with Taguchi method has been used to si...

This research introduces an advanced forging method to produce the door frame of the wind turbine tower. The advantage of the new forging method is the increase of raw material utilization ratio and the energy saving. In the conventional method, the door frame is hot forged with a hydraulic press and machined out lots of material because of the big difference between forging shape and final mac...

Abstract This paper presents the modeling of a cold forging process for rotary sleeve. The EN 42CrMo4 steel part was first modeled numerically by finite element method using simulation software DEFORM 3D ver. 11.0. After that, developed verified experimental tests carried out in laboratory conditions with use 1:2 scale tools and material model aluminum alloy AW-6060. Finite (FEM) results demons...
