Drawing Die Structure


The structure of drawing mould core can be divided into five intervals of "inlet area, lubrication area, working area, fixed diameter area and export area" according to the working nature. The inner diameter profile of the drawing die is very important, which determines the tensile force needed to compress the wire and affects the residual stress in the wire after drawing. The function of each area of the mould core is: The entrance area, convenient threading and prevent the steel wire from the entrance direction scrapes the drawing die; lubrication zone, through which the wire is easy to bring into the lubricant; The working area is the main part of the die hole, the deformation process of the steel wire is carried out here, the original section is reduced to the required section size When drawing a conical metal, the space occupied by the metal in the working area is a round table, which is called the deformation zone. The conical half angle α (also known as the Die Hole half angle) in the working area is mainly used to determine the pulling force size, the function of the sizing area is to obtain the exact size of the drawn steel wire, and the export area is used to prevent the steel wire from not being smooth and scratching the steel wire surface.

pcd diamond copper wire drawing die

Copper plated wire drawing die In the wire industry, the copper wire drawing process is widely used, and the copper wire drawing liquid is generally used as a drawing lubricant to achieve high speed and efficient production. In actual production, the following problems often occur: (1) The copper-plated steel wire ion reacts with the fatty acid anion in the pulling liquid to form a water-insoluble divalent copper-plated steel wire soap. These copper-plated steel wire soaps are clogged in the drawing die, resulting in the emulsion not being completely brought into the die with the copper-plated steel wire, and adhered to the surface of the copper-plated steel wire through the wire drawing die, which causes physical lubrication failure; (2) The copper-plated steel wire ions also react with the unsaturated fatty acids in the drawing liquid to form a dark green sticky substance, an aliphatic polymer, which forms a rapid separation from the water-based system and floats on the surf...
