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...

There are many classification methods of hot-die steels, which can be classified according to the content of alloying elements and the properties after heat treatment, according to their use, or according to alloying elements. (1) According to the use can be divided into hot forging dies steel, hot extrusion die steel, die-casting die steel, hot blanking die steel. (2) According to heat resistance can be divided into low heat-resisting steel (350~370℃), medium-heat-resisting steel (550~600℃), high heat-resisting steel. (3) According to the unique performance of high toughness hot die steel, Gaoje hot as die steel, high wear-resistant hot as die steel. (4) According to the classification of alloy elements can be divided into low alloy hot-die Steel (tungsten series, chromium and molybdenum series), Medium alloy hot-die steel and high alloy hot-die Steel (W-mo system and CR-Mo series), or divided into Tungsten series Gemporg, Chromium series Gemporg and chromium-tungsten-mol...

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 Ho...

The failure of drawing dies can be divided into two types: normal failure and early failure according to the time of occurrence. Normal failure: Drawing die after a large number of production and use, due to friction and natural wear or slow to produce plastic deformation and fatigue crack, to achieve normal service life after the failure is a normal phenomenon, for normal failure.  Early failure: The mold did not meet the design requirements of the time limit, both the collapse of the blade, fragmentation, break, and other early damage, or due to severe local wear and plastic deformation and can not continue to serve, for early failure. For the early failure of the mold, it is necessary to find out the causes of the cause, and strive to take remedial measures. QEDIAMONDDIE is a manufacturer in China.
