Method for creating a thread in at least two work steps |
摘要 |
<p>The method involves producing a preliminary thread in a workpiece (50) e.g. nut, by removing a material from the workpiece with a cutting action, where a preliminary thread profile (21) with two preliminary thread flanks (21A, 21B) and a preliminary thread root is produced. A final thread is produced by plastic pressing-in of the material of the workpiece, where a final thread profile having two final thread flanks and a final thread root is produced. One of the preliminary thread flanks is inclined in a flank section at an inclination angle to a center axis of the preliminary thread profile. An independent claim is also included for a tool set for producing a thread in a workpiece.</p> |
