wire Drawing Process Principle:
Heg
Wire drawing process is a metal pressure processing process, under the action of external force to force the metal through the mold, metal plastic deformation, cross-sectional area is compressed, length increases, and obtain the required cross-section shape and size of the processing method.As the mainstream process route, wire drawing production accuracy depends on the mold.
The Process of Wire Drawing:
Heg
Threading: the wire is released from the coil, and passes through the pay-off stand, all levels of wire drawing die, annealing equipment, and take-up iron shaft in turn. When threading the wire drawing die, the wire is polished with supporting equipment to make the wire diameter smaller and easier to pass through the die holes at all levels of the wire drawing machine.
Wire drawing: refers to the process of plastic deformation of the line embryo through the multistage die hole under a certain pressure, making the section smaller and the length increased, driven by the drawing machine tower wheel shaft step by step drawing. In the process of wire drawing, the drawing liquid plays the role of lubrication, cooling and cleaning.
After wire drawing, it is necessary to carry out continuous annealing, so that the wire hardened due to lattice changes in the cold drawing process is heated by a certain temperature, eliminate internal stress and defects, improve the elongation, so that it can return to the physical and mechanical properties before wire drawing, which is conducive to the follow-up process.
Take-up and inspection: the wire size of each wire diameter is rewound on the take-up iron tray as the enameled specification line or drawing process line. The appearance and size of each axis specification line are fully checked, and the elongation of the process line is separately checked..
Advantages Of Wire Drawing:Heg
Drawing can produce products with precise size, smooth surface and complex section shape.
The production length of the drawn product can be very long, the diameter can be very small, and the section is completely consistent throughout the length.
Drawing can improve the mechanical properties of the product.
