[0002] A wire drawing die is a tool that, during the metal pressure processing process, forces metal to pass through the die under external force. The cross-sectional area of the metal is compressed, and the required cross-sectional area shape and size are obtained; a wire drawing die is a special die through which a metal wire passes and becomes thinner from thick to gradually reach the size required by people; the production of a wire drawing die needs to ensure the accuracy of its shape, size, and surface finish, which is particularly important for the processing of thin wires and wire rods. Any minor error may lead to quality problems in the final product. Among them, the surface finish and accuracy of the die have relatively high requirements for wire drawing dies, directly affecting the forming effect of wire drawing products; the processing of special-shaped wire drawing dies is relatively complex, and many workstations need to be processed with files manually.

Especially for special-shaped wire drawing dies with high difficulty, the processor needs more than 5 years of processing experience. This is the reason for the low processing efficiency and high processing difficulty of special-shaped wire drawing dies. Content of the Utility Model
