Possibilities of application measurement techniques in hot die forging
processes, Measurement: Journal of the International Measurement Confederation 110, pp.
It is also used for smart factories with international-class closed die forging
factories to lead Taiwan enterprises to world markets.
This is of particular significance in the closed die forging
where the stresses in the tools can reach a high level at the final forming stage which may lead to the premature die wear /damage.
The contour method provides a two-dimensional map of residual stresses on a cut surface, which has been applied to measuring internal residual stresses in welding joints [10, 11], 2026-T3511 aluminum alloy component  and die forging
7050-T74 aluminum alloy component .
2 Forging Die, in Impression Die Forging
: Impression die forging
presses metal b/w two dies (tooling) that have a precut profile of the required part.
There are several forging methods such as closed die, press, and upset forging; open die forging
; and cold forging.
The workpieces have been subjected to open a die forging
Other subjects elucidated include die forging
process simulation of a connecting rod, total fatigue life prediction under constant amplitude loading, forces on a circular hole located in functionally graded material, and numerical simulation of fracture saturation in multilayer materials.
turning machines, (c) a new induction tube end heating, also the rehabilitation & modernization of a 500 tons vertical hydraulic press, also (d) an 800 tons die forging
screw friction press.
The raw material was a closed die forging
, and there wasn't much flat on the piece to chuck.
In addition, with design of a die set including die insert and stress ring, cold forging of the bevel gear was experimented to estimate effectiveness of the designed process, in fgure 6) the showm the design process for the closed die forging
of the bevel gear for the 3D FE analysis.
