The contact conditions at the interface between the components during the cold forging process play a crucial role.
Open image in new window Fig. 7 Distribution of the velocity field at different steps during the cold forging process a 34th step; b 64th step; c 84th step; d 104th step Open image in new window Fig. 8 Variation in velocity at various steps in various deformation regions.
In this paper a comprehensive approach is presented for the consideration of the interactions between process, tool and machine during the design of cold forging tools and processes by simulation.
The divided flow method in material plastic deformation is an effective way to reduce the forming force and the die pressure during cold precision forging of helical gears.
Three-dimensional Finite Element (FE) models are established to simulate the plastic deformation process of billet during cold precision forging of a helical gear and to determine the forming force acting on the die.
The results show that the contact-stress behavior observed during hot forging was similar to that observed in cold forging without a lubricant.
Blacksmith, also called smith, craftsman who fabricates objects out of iron by hot and cold forging on an anvil.
In cold forging industry, it is well known that deformation mechanism of the billet and forming tools should be known during forging to properly design the dies and estimate the tool life.
