reduce the stress concentration of the shape
The head of the bolt is where the stress is concentrated. The head of a typical bolt is hexagonal and is shaped from a circle to a hexagon. Cold deformation up to 60% ~ 80, does not allow any folding, especially the cold-headed complex shape flange bolts. However, due to the influence of the precision of the machine tool, the technical level of the operator, the size and quality of the mold, the grain fracture or metal fiber breakage occurs at the joint of the bolt head and the stem. Here the organization is very uneven and forms a brittle fracture danger zone, causing stress concentration. Screws with incomplete thread and full thread shape should be within the allowable range so that the shape is as stress relieved as possible. When adjusting the cold heading machine tool, the gap between the machine tool, the mold clearance, and the machine tool mold should not be neglected. The upset deformation amount of the bolt head should be reasonably distributed, and the transition fillet of the head rod joint should be increased to make the internal organization reach a reasonable state. .
