A. Modeling Guide - Four Steps of Drawing and Modeling and Key Data Calculation Methods

Summary: The drawing die is the work of determining the drawing pass and the size and shape of the drawing die according to the blank size and the wire size when drawing the wire, which is also called the drawing process or the drawing route. Can be divided into single pass wire drawing and multi-pass wire drawing. 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 drawing pass and the distribution pass extension coefficient; 4. matching the die check. And the case of wire drawing of profiled section, specifically introduce the steps and calculation methods of wire drawing.

2. Introduction to the principle of the matching of the sliding wire drawing machine and the calculation of the matching mode

Summary: The wire drawing tool refers to the method of selecting each stretching wire mold during our drawing process. There are two main points for reasonable mold matching. One is mechanical; the sliding type wire drawing machine has its fixed cable speed ratio, and the calculation example of the actual drawing type drawing machine is used to calculate the 7.2mm copper rod to 1.6mm copper wire. number
