Abstract
Способ получения опалубочного профиля холодным редуцированием из полой заготовки, включающий деформирование полой заготовки в валках нескольких последовательно установленных клетей с одновременными обжатием заготовки по ее периметру при сохранении периметра и созданием продольного тянущего усилия при одинаковых скоростях вращения валков во всех клетях и калибровку до получения профиля требуемых размеров и формы, отличающийся тем, что деформирование полой заготовки осуществляют относительно центров жесткости последовательно получаемых профилей при перемещении заготовки от клети к клети, расположенных на одной прямой, совпадающей с осью проката, первоначальной организацией граничных переходных радиусных зон между прямолинейными участками профиля с сохранением наружного периметра заготовки без учета толщины заготовки, последующим формированием прямолинейных участков профиля при условии сохранения постоянными длин дуг формообразующих прямолинейные участки поверхностей профиля и равными длинам соответствующих прямолинейных участков готового профиля изменением радиусов кривизны валков таким образом, чтобы при переходах от одной клети к другой углы подгиба были равными 15-20°.A method of obtaining a shuttering profile by cold reduction from a hollow workpiece, including deforming the hollow workpiece in the rolls of several successively installed stands with simultaneous compression of the workpiece along its perimeter while maintaining the perimeter and creating a longitudinal pulling force at the same speed of rotation of the rolls in all stands and calibration to obtain the profile of the required dimensions and forms, characterized in that the deformation of the hollow billet is carried out relative to the centers of stiffness sequentially floor of the profiles when moving the workpiece from the stand to the stand, located on one straight line coinciding with the axis of the rental, the initial organization of the boundary transition radius zones between the straight sections of the profile while maintaining the outer perimeter of the workpiece without taking into account the thickness of the workpiece, followed by the formation of straight sections of the profile, provided that the lengths are constant arcs of forming straight sections of profile surfaces and equal lengths of the corresponding straight sections of the finished profile HAND radii of curvature of the rolls so that the transitions from one stand to another equal angles hem were 15-20 °.
