　　一. Guide to Die Matching-Four Steps of Drawing Die Matching and Calculation Method of Key Data

　　 Summary: Wire drawing matching die is the work of determining the drawing pass, the size and shape of the die hole of the drawing die according to the size of the blank and the size of the wire during wire drawing, also called drawing program or drawing route formulation. It can be divided into single-pass drawing matching die and multi-pass drawing matching die. The main steps of the drawing die include the following four steps: 1. Select the blank; 2. Determine the number of intermediate annealing; 3. Determine the drawing pass and the distribution pass elongation coefficient; 4. Check with the die. The article is about the circular section metal drawing. In the two cases of wire drawing with special-shaped section metal, the steps and calculation method of drawing die matching are introduced in detail.
