Изобретение относится к обработке металлов давлением и может быть использовано при изготовлении винтовых змеевиков теплообменников. Цель - повышение качества изготовления и расширение области использования змеевиков. Способ включает операция закрепления трубы на оправке с последующей навивкой путем приложения усилия гибки, затем оребренную трубу отжигают и сгибают таким образом, чтобы разность длин двух ветвей составляла половину длины окружности оправки, и подвергают повторному отжигу, потом концы труб отгибают на угол, равный 90-γ, где γ- угол подъема винтовой линии навивки змеевика, отогнутый конец длинной ветви закрепляют на оправке и навивают половину витка змеевика, за этим закрепляют отогнутый конец короткой ветви трубы диаметрально противоположно концу длинной ветви, после чего навивают одновременно две ветви трубы. Оправка для изготовления змеевиков выполнена в виде цилиндра, снабженного головкой с отверстиями, выполненными параллельно оси оправки и расположенными диаметрально противоположно друг другу. 1 з. п. ф-лы.The invention relates to the processing of metals by pressure and can be used in the manufacture of screw coils of heat exchangers. The goal is to improve the quality of production and the expansion of the use of coils. The method includes the operation of fixing the pipe on the mandrel, followed by winding by applying bending, then the finned tube is annealed and bent so that the difference in length of the two branches is half the mandrel circumference, and then annealed again, then γ, where γ is the elevation angle of the helix of the coil winding, the bent end of the long branch is fixed on the mandrel and wound half of the coil turn, and the bent end of the short branch of the pipe is diametrically opposed You can end long branches, and then wound simultaneously two pipe branches. The mandrel for the manufacture of coils made in the form of a cylinder, equipped with a head with holes made parallel to the axis of the mandrel and diametrically opposed to each other. 1 h. apt.
