Explain in brief about the Wire drawing
Drawing: Refers to shaping in a punch press of flat blanks of sheet metal into different shapes. This process is fundamentally forcing the flat sheet of metal into a die cavity with a punch. Force exerted by the punch must be sufficient to draw the metal over the edge of tie die opening and into the die. Metal flow is similar to a viscous fluid. Deep drawing is a special case of drawing when length of the object to be drawn is deeper than its width. For instance washing machine tubes, aluminium milk churns.
