Description
нал на регул тори мощности 2, которые перераспредел ют энергию высокочастотного генератора 1 между наружное 4 и внутренней 5 секци ми индуктора в соответствии с установленно программой нагрева биметаллическоП заготовки.The power was set at power regulator 2, which redistributes the energy of high-frequency generator 1 between the outer 4 and inner 5 sections of the inductor in accordance with the established bimetallic billet heating program.
После сборки заготовки 6 механизм по ачи (на чертеже не показан) подает ее с посто нной скоростью в индуктор со стороны внутренней секции 5-.. При прохождении заготовки 6 через секции 5, 4 тепловой энергией воздействуют сначала на внутреннюю, а затем на наружную поверхности заготовки . После выхода заготовки из индуктора производ т ее пластическую деформацию до нужных размеров.After assembly of the workpiece 6, the gear mechanism (not shown in the drawing) delivers it at a constant speed to the inductor from the inside section 5- .. When the workpiece 6 passes through sections 5, 4, thermal energy is applied first to the inside and then to the outside surface blanks. After the preform leaves the inductor, it is made of plastic deformation to the desired size.
При вводе тепловой энергии через внутреннюю поверхность заготовки ее внутренний слой, увеличива сь в диаметре , постепенно вытесн ет воздух из сборочного зазора. Благодар удлинению более нагретого внутреннего сло контактное давление между сло ми :ia фронтом нагрева максимально.When heat energy is introduced through the internal surface of the workpiece, its inner layer, increasing in diameter, gradually displaces the air from the assembly gap. Due to the elongation of the more heated inner layer, the contact pressure between the layers: ia is the maximum of the heating front.
Последовательное введение тепловой энергии через наружную поверхность позвол ет сохранить высокое знчение контактного давлени и получит одинаковую кривизну слоев по всей длине заготовки.Sequential introduction of thermal energy through the outer surface allows one to maintain a high value of contact pressure and obtains the same curvature of the layers along the entire length of the workpiece.
В процессе нагрева наружного сло кривизна его контактирующей поверхности увеличиваетс и приближаетс к кривизне поверхности переходного сло , при этом контактное давление в переходном слое выравниваетс по длине и по сечению.In the process of heating the outer layer, the curvature of its contacting surface increases and approaches the curvature of the surface of the transition layer, while the contact pressure in the transition layer is equal in length and cross section.
Переходной слой биметаллических труб, полученных по предложенному способу с использованием реализующего его устройства, имеет бездефектное качество сцеплени металлов.The transition layer of bimetallic pipes, obtained by the proposed method using the device that implements it, has a defect-free quality of adhesion of metals.
