Matching method of special-shaped wire drawing die:
1. Die Matching Guide-Four Steps of Drawing and Matching Die and Calculation Method of Key Data
Summary: The 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 the drawing of the metal wire. It is also called the formulation of the drawing program or the drawing route. 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 distribution pass elongation coefficient; 4. Check with the die. The article is about the circular cross-section metal drawing. In the two cases of metal wire drawing with special-shaped cross-section, the steps and calculation methods of drawing die matching are introduced in detail.
2. Introduction to the principle of sliding wire drawing machine mold matching and calculation examples of mold matching
Summary: Wire drawing matching die refers to the method of selecting each drawing wire die during our drawing process. There are two main points for reasonable die matching. One is machinery; the sliding wire drawing machine has its fixed drawing wheel speed ratio. Through the calculation example of the real-moving wire drawing machine die matching calculation, the correlation of drawing 7.2mm copper rod to 1.6mm copper wire is calculated. data.
