Claims (1)

Способ изготовления угольника из тонкостенной трубчатой заготовки, включающей операции сплющивания центральной части трубчатой заготовки, гибку сплющенной части, раздачу сплющенной и изогнутой части заготовки внутренним давлением, отличающийся тем, что, с целью снижения затрат на изготовление угольника из трубчатой заготовки, длина которой не превышает три-четыре ее диаметра, путем совмещения операций и уменьшения энергоемкости процесса, а также улучшения качества изделия за счет уменьшения площади поверхности сплющиваемой части заготовки, заготовку перед сплющиванием и гибкой устанавливают в двух симметричных металических оправках с сердечниками гибочного устройства с охватом заготовки по всей длине по наружному и внутреннему диаметру, а затем осуществляют одновременное сплющивание и гибку центральной части трубчатой заготовки взаимным разворотом оправок с сердечниками относительно оси, отстоящей от наружного диаметра трубчатой заготовки на одну-две ее толщины с фиксацией наружного диаметра заготовки в направлении, перпендикулярном плоскости изгиба.A method of manufacturing a square from a thin-walled tubular billet, including the operations of flattening the central part of the tubular billet, bending the flattened part, distributing the flattened and bent part of the billet with internal pressure, characterized in that, in order to reduce the cost of manufacturing a square from a tubular billet, the length of which does not exceed three - four of its diameter, by combining operations and reducing the energy intensity of the process, as well as improving the quality of the product by reducing the surface area of the flattened part for the preparations, the workpiece before flattening and bending are installed in two symmetrical metal mandrels with the bending device cores covering the workpiece along the entire length along the outer and inner diameters, and then the central part of the tubular workpiece is simultaneously flattened and bent by mutual rotation of the mandrels with the cores with respect to the axis spaced from the outer diameter of the tubular workpiece at one or two of its thickness with fixing the outer diameter of the workpiece in the direction perpendicular to the plane of bending.
