Изобретение относитс к способам изготовлени рогообразных сердечников, используемых при гибке труб.This invention relates to methods for making horn-like cores used in tube bending.
Известен способ изготовлени рогообразного сердечника путем механической обработки его основы.There is a known method for making a horn-like core by machining its base.
Основной недостаток известного способа - низкое качество гибки по причине плохого качества поверхности сердечника.The main disadvantage of this method is the low quality are flexible due to the poor quality of the surface of the core.
С целью повышени качества гибки в качестве основы сердечника берут предварительно изогнутый стержень, диаметр отогнутой части которого больше пр молинейной части , а перед механической обработкой на стержень напрессовывают цилиндрическую оболочку, после чего стержень с оболочкой сваривают по торцам.To improve the quality of bending, a pre-bent rod is taken as the core core, the diameter of the bent part of which is larger than the straight part, and before machining a cylindrical shell is pressed onto the rod, after which the core and shell are welded to the ends.
На чертеже изображена последовательность операций при изготовлении сердечника.The drawing shows the sequence of operations in the manufacture of the core.
Цилиндрическую оболочку 1 устанавливают на предварительно изогнутый стержень 2, обжимают и сваривают стержень с оболочкой по торцам дл получени рогообразного сердечника 3.The cylindrical shell 1 is mounted on a pre-curved rod 2, the core is sheathed and welded to the shell at the ends to form a horn-like core 3.
