The matching mode of the special-shaped wire drawing die:

I. Die matching guide-four steps of drawing die matching and calculation method of key data

Summary: The drawing die is the work of determining the drawing pass, the hole size and shape of the drawing die according to the size of the blank and the size of the wire when drawing the wire. It is also called drawing process or drawing route. Can be divided into single-pass wire drawing die and multi-pass wire drawing die. The main steps of the drawing die include the following four steps: 1. selecting the blank; 2. determining the number of intermediate annealing; 3. determining the elongation coefficient of the drawing pass and the distribution pass; 4. matching the die check. And special-shaped cross-section metal wire drawing, specifically introduce the drawing die matching steps and calculation methods.

2. Introduction of mold matching principle and calculation example of sliding wire drawing machine

Summary: The drawing die refers to the method of selecting each drawing wire die during the drawing process. There are two main points for a reasonable die matching. One is mechanical. The sliding wire drawing machine has its fixed wire drawing wheel speed ratio. Through the calculation example of the real wire drawing machine, the correlation between the 7.2mm copper rod and 1.6mm copper wire is calculated data.
