| Abstract: | The deformation of matel of the high strength inner hexagonal bolts are analysed. An expression for the strain of metal flow around the corner of an ianer hexagonal bolt is proposed. The fracture limit for materials has been derived after tests on 35CrMoA and other materials. The results are useful to cold forging production of axis symmetrical and polygonal cavity parts. |
