Effects of working speed (v) of die and lubricant on frictional characteristics of C5191 copper alloy during cold forming process are studied. The friction on contact surface is mainly caused by slight ploughing in small deformation and tearing after ...

Simulation of industrial cold forming processes
Communications in Applied Numerical Methods, 1987AbstractA microcomputer‐based system for the simulation of cold metalforming processes is described. The simulation uses a nonlinear elastic–plastic finite element method developed for use on a 16‐bit microcomputer. The suitability of such a system is demonstrated by reviewing its application to industrial forming processes such as heading and ...

Energy Evaluation of Cold-Forming Processes
CIRP Annals, 1990Summary The contribution first discusses the specific energy consumed in cold forming processes. In order to make on objective comparison of the specific energies consumed in forming as opposed to cutting, the paper proposes the introduction of a new parameter called the degree of structure fineness S. Considering this parameter an energy evaluation

Virtual Process Design for Cold Formed Components
Key Engineering Materials, 2015Finite element models optimizing cold forged products have to incorporate the complete manufacturing pathway. Virtual process design as a method based on a multistep operation approach can describe interacting phenomena. Thus, inheritance effects like residual stress and damage evolution can be tracked throughout the processing chain.

Some comments on cold forming process stability analysis
Journal of Materials Processing Technology, 2003Abstract The paper deals with accuracy problems in different forming processes. In cold forging, the outcoming part is exactly defined with tolerances and mechanical properties. On the incoming side, where the material is defined, the definition of geometry and mechanical properties fluctuations is not so clear, because they depend also of the chosen

Zweistufiges Kaltumformungsverfahren für Zahnräder/Two-stage cold forming process for gear wheels
wt Werkstattstechnik online, 2022Das Querfließpressen wird seit mehreren Jahren zur Fertigung von Stirnrädern verwendet. Dieses Verfahren erfordert hohe Prozesskräfte für die Ausfüllung zahnförmiger Kavitäten, was die Werkzeugstandzeit und die Werkstückqualität reduziert. Am Institut für Umformtechnik IfU wurde das Free-Divided-Flow-Verfahren (FDF) entwickelt, um beim Prägen die ...

Nitridable steels for cold forming processes
Metallurgical Transactions A, 1981Low carbon titanium steels with nickel and/or manganese and silicon additions were developed to combine formability, nitradability with increased strength. The strength, formability, and nitradability of 16 different compositions were investigated. Neither the depth nor the great hardness of nitrided layers, due to TiN particles < 15A in size, was ...

Investigations on cold-forming effect of cold-drawn duplex stainless steel tubular sections
Journal of constructional steel research, 2019The cold-drawing process is currently a significant way of manufacturing cold-formed structural tubular sections at room temperature. Furthermore, cold-drawing is more suitable for forming thick-walled sections with large dimensions than cold-rolling ...
