Finite element analysis of header dies for taper upsetting

In upset forging, the part is generally formed by a series of operations. Generally, taper upsetting stages are used as preforms. The geometry of the die cavity for the taper preforms can easily be determined from the dimensions of the hot part at the related stages; however the outer dimensions of the header die are determined by using some empirical formulae. In this paper, a commercial finite element code coupled with thermal analysis has been used to simulate hot upset forging process and to examine effects of the process on header die wall and base thicknesses for the taper preform stages. The stress distribution for different wall and base thickness values of the header die has been evaluated and presented. © 2006 Civil-Comp Press.

Finite element analysis of the effects of tapered preforms on the final product in cold upsetting
Dogan, O.; Gökler, Mustafa İlhan; Darendeliler, Haluk (null; 2002-12-01)
The effects of the tapered preform shapes on the final product in cold upset forging are presented. As such, different preform geometries with different upset ratios are considered for the same final part geometry. In addition, the elastic-plastic finite element method is used to examine die filling and determine the flash volume in the final stage for different preform geometries. It is observed that, well-filled final products are obtained when the preform shapes and die cavities are designed according to...
Analysis of tapered preforms in cold upsetting
Gökler, Mustafa İlhan; Darendeliler, Haluk (1999-01-01)
Upset forging is usually carried out with a sequence of stages and the tapered preforms are commonly used. The preforms should be free from flash formation and buckling injuries. :In this paper, the results that depend on elastic-plastic finite element analysis of taper upset forging are given. The buckling analysis was realized by using the Modified Riks method. For a given upset ratio which is the ratio of unsupported length to diameter of the initial billet, reduction in the height of the billet and the ...
Analysis of forging for three different alloy steels
Civelekoğlu, Barış; Darendeliler, Haluk; Gökler, Mustafa İlhan; Department of Mechanical Engineering (2003)
Forging is a manufacturing process which is preferred among the others in that, the final product shows more enhanced properties. The properties of the final product are directly related with the material used in the forging process. Main parameters such as forging temperature, number of stages, preform design, dimensions of the billet, etc. may be affected by the forging material. Alloys are one of the main areas of interest in the forging industry. The use of alloy steels may bring superior properties, es...
Analysis and preform design for long press forgings with non-planar parting surfaces
Karagözler, Ahmet Barış; Gökler, Mustafa İlhan; Darendeliler, Haluk; Department of Mechanical Engineering (2003)
In industry, a wide variety of parts are produced by press forging. Press forging generally requires sequential forming of workpieces through a set of preforming stages before the final stage. The design of preform dies affects die and product cost and quality. To ensure complete filling of the die at the final stage, companies in the forging industry commonly add extra material to the original workpiece volume and accordingly design the perform dies by the help of their experience. However, this method ref...
Finite element analysis of shearing processes
Isbir, S.; Darendeliler, Haluk; Gökler, Mustafa İlhan (null; 2006-12-01)
Shearing of sheet metal is extensively used in manufacturing industry. It is a highly non-linear process and involves complex mechanisms such as crack initiation and propagation, and deliberate fracture of the material for obtaining the desired geometry. Finite element method can be used for the design of shearing process. However, most of the general purpose commercial finite element analysis programs do not provide ready-to-use facilities to simulate shearing. In this paper, finite element simulation of s...
