Optimization of Flash, Billet Dimensions and Friction Factor in Closed Die Cold Forging Process
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...
متن کاملOpen-Die Forging of Structurally Porous Sandwich Panels
Structurally porous metal sandwich panels consisting of dense face sheets and porous cores of controlled relative density can be manufactured by trapping inert gas during hot isostatic pressing and modifying its distribution via subsequent thermomechanical forming. A plane-strain solution for analyzing the open-die forging of such a plastically compressible sandwich panel is developed. An effec...
متن کاملPrediction of Residual Stresses for a Hollow Product in Cold Radial Forging Process
Radial forging is an open die forging process used for reducing the diameters of shafts, tubes, stepped shafts and axles and also for creating internal profiles such as rifling the gun barrels. The radial forging of tube is usually performed over a mandrel to create an internal profile and/or size the internal diameter. Most of the previous studies conducted on the radial forging process have u...
متن کاملOptimization Design of Flash Structure for Forging Die Based on Kriging-PSO Strategy
The article concern the influences of the novel flash structure with resistance wall on the forming load and die wear during the closed-die forging process. If the geometrical parameters of the resistance wall are not properly designed, the forming load and die wear may be great; this can affect the life of the forging die. Yet, no procedure is known to optimize and decide this flash structure ...
متن کاملdesign of the die profile for the incremental radial forging process
in this paper, based on the slab method of analysis, a novel and general approach isdeveloped for studying the radial forging process with curved profile dies. the presented approachis not only more general with respect to previous studies, but it is also easier to understand and useand can be efficiently used for optimization of the die profile depending on the forging geometryand conditions. ...
