Description
При изготовлении трубных угольников и двойников прот гиванием трубной заготовки по эксцентричному дорну часто образуютс разрывы и трещины на изделии.In the manufacture of pipe squares and twins by pulling the pipe billet along an eccentric mandrel, breaks and cracks are often formed on the product.
Существо описываемого способа изготовлени трубных угольников и двойников заключаетс в том, что трубную заготовку надевают на неподвижный эксцентричный дорн и проталкивают через матрицу, рабочему ручью которой придана форма в виде суживающегос конуса с пр молинейными образующими.The essence of the described method of making pipe elbows and twins is that the pipe billet is put on a stationary eccentric mandrel and pushed through a matrix, the working stream of which is shaped in the form of a tapering cone with straight lines.
При изготовлении трубных угольников н двойников описываемым способом устран ютс разрывы и трещины на изделии.In the manufacture of pipe squares n doubles, the described method eliminates gaps and cracks on the product.
На чертеже схематически показано устройство дл осуществлени описываемого способа изготовлени трубных угольников и двойников, в двух проекци х.The drawing shows schematically a device for carrying out the described method for manufacturing pipe gons and twins, in two projections.
Дл осуществлени способа трубна заготовка 1 надеваетс на неподвижный дорн 2 и толкателем 3 подаетс через матрицу 4, рабочий ручей 5 которой выполнен в виде эксцентричного суживающегос конуса.For the implementation of the method, the tubular billet 1 is put on the stationary mandrel 2 and the pusher 3 is fed through the die 4, the working stream 5 of which is designed as an eccentric tapering cone.
Между матрицей и сердечником 6 дорна на выходе устанавливаетс зазор, равный толщине стенки трубы с учетом необходимого допуска.Between the matrix and the core 6 of the mandrel, a gap is established at the exit, equal to the thickness of the pipe wall, taking into account the necessary tolerance.
Вследствие неравномерного обжима трубной заготовки стенка по линии АБ не подвергаетс сжатию и не удлин етс , а по линии ВГ происходит паибольшее сжатие с утолщением стенки и носледующим принудительным утонением.Due to the uneven crimping of the tube blank, the wall along the AB line is not compressed and does not lengthen, and along the VG the greatest compression occurs with wall thickening and with the next forced thinning.
В результате неравномерного удлинени стенок трубной заготовки она нринимает криволинейную форму в сечении АВ.As a result of the uneven elongation of the walls of the tube blank, it draws a curvilinear shape in section AB.
Предмет изобретени Subject invention
Способ изготовлени трубных угольников и двойников путем прот гивани 1 рубной заготовки по эксцентричному дорну, о т л и ч а ю щ и йс тем, что, с целью устранени разрывов и трещин на изделии, трубную заготовку надевают на ненодвижный дорн и дл осуществлени обжима нроталкивают через матрицу, рабочему ручью которой нридана форма в виде суживающегос конуса с нр молинейными образующими.The method of making pipe squares and twins by pulling a 1-inch billet along an eccentric mandrel, is so that, in order to eliminate gaps and cracks on the product, the tubular blank is put on a non-movable mandrel and is pressed to repress through the matrix, to the working stream of which there is a nridana form in the form of a narrowing cone with non-linear generators.
