Description
Известен способ изготовлени профилей с плоскими полками из полосовых заготовок, при котором участки заготовки, образующие в готовом профиле полки, подгибают, последовательно увеличива угол гибки до получени требуемого профил .A known method of manufacturing profiles with flat shelves of strip blanks, in which the areas of the blank forming the shelves in the finished profile are folded in, successively increasing the bending angle to obtain the desired profile.
Предлагаемый способ отличаетс от известного тем, что участки заготовки, образующие полки в готовом профиле, в процессе подгибки деформируют, вначале придава им криволинейный контур в плоскасти поперечного сечени , а затем выправл их.The proposed method differs from the known one in that the parts of the workpiece that form the shelves in the finished profile are deformed during the bending process, first giving them a curvilinear contour in the flatness of the cross section, and then straightening them.
Это позвол ет предотвращать волнистость кромок изготовл емого профил .This prevents the corrugation of the edges of the manufactured profile.
Сущность описываемого способа заключаетс в том, что деформированные в процессе подгибки полки профил увеличивают его жесткость и тем самым позвол ют, в особенности при пибке тонколистовых заготовок, избежать волнистости кромок профил .The essence of the described method is that the profiles deformed during the hemming process increase the rigidity of the profile and thereby allow, especially when pibka thin-sheet blanks, to avoid waviness of the edges of the profile.
На последних переходах профилировани кривизну нолок выправл ют н получают профили с ПЛОСКИМИ полками.On the last profiling transitions, the curvature of the nolok is straightened and profiles with FLAT shelves are obtained.
Предмет изобретени Subject invention
Способ изготовлени профилей с плоскими полками из полосовых заготовок, при котором участки заготовки, образующие полкИ в готовом профиле, подпи1бают, последовательно измен угол гибки до получени требуемого профил , отличающийс тем, что, с целью предотвращени волнистости кромок профил , упом нутые участки в процессе подгибки деформируют, вначале придава им криволинейный контур в плоскости поперечного сечени , а затем выправл их.A method of manufacturing profiles with flat shelves of strip blanks, in which parts of the blank forming the regiments in the finished profile are signaled by successively changing the bending angle to obtain the desired profile, characterized in that, in order to prevent the profile edges from waving, the said sections in the bending process they deform, first giving them a curvilinear contour in the plane of the cross section, and then straightening them.
