Strength of a Threaded Joint on Cut in Holes with Flanges Formed by a Rotating Punch in Thin-Sheet Work-Pieces

Abstract:

The main problem of shaping threaded holes in sheet blanks with a thickness of less than two millimeters is to obtain a threaded surface that provides the necessary strength of the threaded connection. The method of forming holes with flanges in sheet blanks by rotating punch (thermal drilling) has wide technological capabilities. The rotational speed of the punch, as well as its axial feed, affect the shape, size and properties of the material of the resulting hole, which in its turn affects the length of the screwing and the strength of the threaded joint.
