Energy-power characteristics when drawing a trimetal billet

Computer analysis of the deformation mode of the drawing tool for platinum alloys

“…In the general case, when designing the drawing technology, it is necessary to monitor, select, and optimize the stresses in the wire and a die; plastic deformation and wire strengthening; cross sec tion area; application of lubricants; process velocity; and die conicity angle [11]. The conicity angle, which is the slope angle of the tool generatrix to the drawing axis, plays an important role, since it determines the energy-power process parameters and should provide minimal drawing stress [12]. Process productivity in many aspects depends on tool stability and is deter mined by the level of stresses in a contact zone [13].…”
