The paper considers the technological process of deep drawing, taking into account high degree deformation metal and small thickness (0.5 mm) workpiece. Given complexity impossibility its representation in an analytical form, uses form a phase portrait plane drawing force movement hydraulic press punch. Phase trajectories mentioned determine geometric dimensions product, characterize stresses d...

Abstract The paper shows a significant influence of the multi-stage wire drawing technology on deformability and phase transformations in zinc coating. SEM tests proved that coating after hot-dip galvanizing consists number thin layers, ranging from 1 to 5 µm, differing thickness, chemical composition properties. When pulled through die heats up (as result friction between material tool) its dy...

The effects of steel wire patenting process parameters on very fine interlamellar spacing in the pearlitic steel wire were investigated and the optimized condition of the process was achieved. In this work, the initial nanopearlitic structure was obtained in a 0.72 wt% carbon steel wire before the wire drawing process. The results were the minimum interlamellar spacing of 35 nm and maximum ulti...

use of tailor-welded blanks (twbs) in production has significant advantages such as weight and cost reduction. however, their application requires processes that increase their poor formability in comparison to base materials. one of these procedures is the use of fluid pressure in sheet metal forming. in this paper hydro-mechanical deep drawing process of tailor-welded low carbon steel (st12) ...
