Description
(54) СПОСОБ СБОРКИ МНОГОСЛОЙНОЙ ТРУБЫ(54) METHOD FOR ASSEMBLY OF MULTILAYER PIPE
1:one:
Изобретение относитс к области изготовлени многослойных труб, преимущественно тонкостенных.The invention relates to the manufacture of multilayer pipes, preferably thin-walled.
Известен способ изготовлени многослойной трубы путем последовательного надвигани трубйых элементов с последующей их термообработкой 1.A known method of manufacturing a multilayer pipe by successively advancing the pipe elements with their subsequent heat treatment 1.
Недостатком этого способа вл етс то, что он сложен и качество трубы недостаточно высокое.The disadvantage of this method is that it is complicated and the quality of the pipe is not high enough.
Известен также способ изготовлени многослойной трубы путем последовательного надвигани трубных элементов, включающий калибрование меньщего элемента путем раздачи на оправке 2.There is also known a method for manufacturing a multilayer pipe by successively advancing the pipe elements, including calibrating the smaller element by dispensing on the mandrel 2.
Недостатком известного способа вл етс его сложность и низкое качество трубы, обусловленное применением смазки и наличием задиров на поверхност х трубных элементов. The disadvantage of this method is its complexity and the poor quality of the pipe, due to the use of lubricant and the presence of scoring on the surfaces of the tubular elements.
Целью изобретени вл етс упрощение сборки.The aim of the invention is to simplify the assembly.
Эта цель достигаетс тем, что согласно способу сборку ведут с использоййнием дополнительных двухступенчатых оправок, при этом в свободный конец с меньшим диаметром трубного элемента ввод т ступень оправки меньшего наружного диаметра, а каждый последуюишй трубный элемент надвигают через другую ступень оправки, одновременно его калибру . 5This goal is achieved in that, according to the method, the assembly is carried out using additional two-stage mandrels, while the mandrel stage of the smaller outer diameter is inserted into the free end with a smaller diameter of the tubular element, and each subsequent tubular element is pushed through another mandrel step, simultaneously with its caliber. five
На чертеже схематично изображена многослойна труба в процессе сборки.The drawing schematically shows a multilayer pipe during assembly.
Сборку многослойной трубы осуществл ют следующим образом.The assembly of the multilayer pipe is carried out as follows.
10 На Оправку 1 одевают трубный элемент 2 и тем самым его калибруют. Затем в трубный элемент 2 ввод т двухступенчатую оправку 3, а именно ее ступень 4 меньшего наружного диаметра.10 On mandrel 1 wear pipe element 2 and thereby calibrate it. Then a two-stage mandrel 3 is inserted into the tube element 2, namely, its step 4 of a smaller outer diameter.
Через ступень 5 оправки 3 надвигают 5 следующий трубный элемент 6 на трубный элемент.Through the stage 5 of the mandrel 3 push 5 the next pipe element 6 on the pipe element.
Каждый следующий трубный элемент Надвигают аналогично.Each next pipe element Slide similarly.
Надвигание трубных элементов возможно , осуществл ть, например, посредством нат жных валиков 7 и 8.It is possible to push the tube elements, for example, by means of tension rollers 7 and 8.
