For samples exchanged for each type of product test die, 5"200 pieces shall be scrapped when cold headings are used, especially in areas where stress is concentrated.
5, good metal flow line
The fibrous structure of the metal flows in the rolling direction. Such brittle grains such as carbides are refined during cold crucible and cold extruding processes, and the crystal grains become thin and elongated in the direction of elongation, which leads to the guide. This fibrous structure is the fiber streamline produced by deformation after plastic processing. When the bolt is cold upset, especially at the connection of the head bar, if the quality of the cold upsetting is poor, the plastic flow line of the head fiber will be disordered and cut off. This is a defect that cannot exist for high-strength bolts, which will lead to the occurrence of delayed fracture. .
