The basic structure of the drawing die

　　The basic structure of the wire drawing die. The main working area of the wire drawing die is the inner hole. The inner hole structure can be divided into the entrance area,

　　, Lubrication zone, sizing zone, outlet zone and five zones and follow the "smooth transition" theory, namely the wire drawing die hole

　　The junction of the inner districts must be a small rounded transition. The drawn wire enters the wire drawing die from the entrance, and it acts on the drawing force i

　　Down through the drawing die, and violent friction occurs on the tapered surface of the working area of the drawing die, and pull out from the exit to obtain a smaller wire.
