Abstract

Cold drawing is the final process of plastic deformation in the manufacture of precision steel seamless tubes. This particular technology is utilities by multiple drawing operations (sequences) with intermediate heat treatment. The different drawing methods are differentiate according specification of the inner diameter of the tube. Hollow sinking process is simply drawing the tube through and reducing the outside and inside diameters without using an internal support (tool). Plug drawing is used to achieve wall thickness and inner diameter. According to the shape it is possible to distinguish the plugs on the conical and cylindrical. A modern approach to solving complex technological issues is the use of numerical simulations based on the finite element method. In this paper, stress-strain states describing the flow of material will be analysed, as well as the geometry of tribological pairs of forming tools with respect to the drawing force. The results are verified in technology in order to improvement production and reduce economic costs.
