Description
Известна оправка дл прот жки труб, включающа цилиндрическую часть и съемную головку с механизмом ее 1еремешени .A known mandrel for drawing pipes, including a cylindrical part and a removable head with a mechanism for its mixing.
С целью получени труб с утоненными передним и задним концами, у предложенной оправки головка и хвостова часть выполнены конусными с увеличенными к концам оправки диаметрами .In order to obtain pipes with thinned front and rear ends, in the proposed mandrel, the head and tails portion are tapered with diameters increased towards the ends of the mandrel.
На чертеже показана предложенна оправка .The drawing shows the proposed mandrel.
Оправка состоит из цилиндрической части I, головки 2, выталкиваюи1его механизма 3, хвостовой части 4. Головка выполнена профильной , например конической, причем диаметр ее возрастает по мере удалени от цилиндрической части. Хвостова часть 4 также выполнена , например, конической, с унеличеиием диаметра от цилиндрической части.The mandrel consists of a cylindrical part I, a head 2, an ejector mechanism 3, a tail part 4. The head is shaped, for example conical, and its diameter increases with distance from the cylindrical part. The tail part 4 is also made, for example, conical, with the diameter extended from the cylindrical part.
Прот жка на оправке осуществл етс следующим образом.The mandrel is drawn as follows.
На собранную оправку надевают гильзустакан 5. Во врем прохождени гильзы через стан она на одном конце принимает профильA sleeve is put on the assembled mandrel 5. During the passage of the sleeve through the mill, it receives a profile at one end
головки 2, а на другом - профиль хвостовой части 4.heads 2, and on the other - the profile of the tail section 4.
По окончании прот жки на стане выталкивающий механизм 3 приводит в движение головку 2, донышко отрываетс по месту сопр жени с трубой. Головка выталкиваетс через открывающеес отверстие гильзы 5, остальна часть оправки извлекаетс в обратном направлении . В результате получаетс труба с утоненными концами.At the end of the stretching on the mill, the ejector mechanism 3 sets in motion the head 2, the bottom is detached at the place of interface with the pipe. The head is pushed through the opening of the sleeve 5, the rest of the mandrel is removed in the opposite direction. The result is a pipe with thinned ends.
