The processing flow of cold-drawn steel produced by combined drawing machine

The processing flow of cold-drawn steel produced by the joint drawing machine: 1. Raw material wire rod (the section shape can be round, square, hexagonal, flat or abnormal-shaped); 2. Uncoiling and feeding; 3. 4. Pre-straightening: The purpose is to straighten the raw materials and remove some of the stress to provide higher efficiency for the entire production line. 5. Mold: use tungsten steel mold or poly crystal mold. The choice of the mold and the manufacturer of the mold is particularly important, the mold is mainly reflected in the material diameter tolerance accuracy after drawing, service life, drawing speed, whether it will draw hair and whether it is easier to straighten.
