Innovations in cold forging die design
Journal of Materials Processing Technology, 2000Abstract The demand of the market to the major industrial cold forgers for the development and production of complicated net shape parts at fairly low unit costs requires innovative new die designs for the optimisation of die deflections. The high-stiffness STRECON ® E + containers influence the stresses, strains, and deflections in critical dies ...

Fillet design in cold forging dies
Computers & Structures, 1994Abstract Tools for cold forging are subjected to heavy loads due to precompression of the die as well as internal pressure caused by the actual forging process. This is observed especially when the geometry includes details such as sharp fillets, which act as stress raisers and thereby lead to imminent danger of cracks and destruction of the tool ...

A microalloyed (MA) forging steel is non-heat-treated materials that have been replacing for conventional quenched and tempered (Q/T) structural steels since the MA forging steels are very cost-effective compared with Q/T steels for the production of automotive parts.

Cold forging of sintered iron-powder preforms
Journal of Materials Processing Technology, 1995Abstract The paper reports on an investigation into various aspects of cold forging of iron-powder preforms which have been compacted and sintered from atomised iron powder. An upperbound solution is constructed for determining the die pressures developed during the cold forging of iron powder under axisymmetric and plane-strain condition.

Computer-Aided Production Planning in Cold Forging
CIRP Annals, 1980A programme system is presented that permits the computer-aided layout of process planning in cold forging. Besides the determination of the manufacturing sequence, the programme system deals with the manufacture of billets, heat treatment and surface treatment, the calculation of the most important parameters of the production operations, and with ...

An advanced press design for cold forging
Journal of Materials Processing Technology, 1997Abstract Forging has features that distinguish it from other shaping methods, and especially net shape forming is the ultimate target of forging. To complete the target, improvement of accuracy of the forged parts is essential. Accuracy of forged parts is affected by various factors, among which, characteristics of the forging machine are one of the ...

This article analyses the basic mechanisms of tribological wear due to tribological processes that occur during cold and hot forging. Forging dies surface wear has a large influence on the product surface quality so it is necassary to reduce the waer intensity as much as possible.
