Analysis on the working principle of drawing die for drawing

　　my country is a large wire rod producer, and its output ranks among the top in the world. Wires are widely used in communications, construction, power and other sectors. In wire production, drawing processing is the most commonly used processing method. The application range of drawing processing is very wide, mainly used for drawing straight materials such as bars and wires. Drawing production solves the problem of wire rods that are difficult to process by turning and other methods. Its processing accuracy is relatively high, and its processing speed is fast, the degree of waste to the blank is low, and the utilization rate is high. The wire drawing die is a very important consumable die in the drawing production of various metal wires. The cost of the wire drawing die accounts for more than 50% of the drawing cost. At present, the commonly used wire drawing dies include alloy steel dies, cemented carbide dies and diamond dies, and various drawing dies have their own advantages and disadvantages in the use process. Now the working principle of the drawing die and the materials of the commonly used drawing die, the classification of the wear of the drawing die and the influencing factors of the drawing process are described below.
