Wire drawing dies are usually operated under high temperature and high pressure. Under the influence of pressure and temperature, the die appears elastically deformed. The mold working belt is parallel to the kneading direction at the beginning. After being pressed, the working belt is transformed into a horn shape, as long as the cutting edge of the working belt touches the sticky aluminum formed by the profile, similar to the cutting edge of the turning tool. During the entire formation process of sticking aluminum, particles are continuously carried out by the profile and adhered to the skin surface of the profile, resulting in "adsorbed particles". in metal press working. Under the action of external force, the metal is forced through the die, the metal cross-sectional area is compressed, and the tool that obtains the required shape and size of the cross-sectional area is called a wire drawing die. A wire drawing die is a metal wire passing through a die to make it from thick to thin and gradually reach the size that people need. This special die is a wire drawing die. A wire drawing die is a kind of die, which is mainly used on relatively soft metal materials, such as aluminum or copper. The die is fixed in a machine and the metal material is forced through the wire drawing die, and then a brighter product is obtained. Generally, the structure of the wire drawing die For inlaid structure, the outside is steel such as 45# steel or CR12.
