What are the methods to improve the quality of drawing die
Drawing die is usually operated in the state of high temperature and pressure. Affected by pressure and temperature, the appearance of elastic deformation of the die occurs. The die working belt is parallel to the kneading direction from the beginning. After being pressed, the working belt is changed into a trumpet shape. As long as the cutting edge of the working belt is composed of some touch profiles, it is similar to the knife chip tumor of the turning tool. In the whole formation process of aluminum bonding, particles are constantly taken out by profiles and adhered to the surface of the profiles, resulting in "adsorbed particles".
In metal pressure working. The tool that forces the metal through the die under the action of an external force, the cross-sectional area of the metal is compressed, and the required cross-sectional area shape and size is called a wire drawing die. Wire drawing die is a metal wire through a mold, so that it from coarse to fine, gradually reach the size that people need, this special mold is the wire drawing die.
Wire drawing die is a kind of die, which is mainly used in soft metal materials, such as aluminum or copper. The die is fixed in a machine, so that metal materials are forced through the wire drawing die, and then the more bright products are obtained. The structure of wire drawing die is Mosaic structure, and the outside is steel, such as 45# steel or CR12.
