Известна оправка для намотки раструбной части трубы, содержащая разъемный цилиндрический корпус с конусными кольцами на конце [21.Known mandrel for winding the bell-shaped part of the pipe containing a detachable cylindrical body with conical rings at the end [21.

. Однако такая конструкция извест- *0 ной оправки не обеспечивает получение раструба, на внутренней поверхности которого имеются профилированные углубления.' _. However, this design of the well-known * 0 mandrel does not provide a bell, on the inner surface of which there are profiled recesses. ' _

Цель изобретения - формование при *·* намотке профилированного раструба.The purpose of the invention is the molding when * · * winding a profiled socket.

Указанная цель достигается тем,что на оцравке, содержащей разъемный цилиндрический КОРПУС С КОНУСНЫМИ КОЛЬ’ цами на конце, в месте стыка колец 30 по внешнему периметру выполнена кольцевая проточка, в которой уложено профилированное резиновое кольцо.This goal is achieved by the fact that, on a bench containing a detachable cylindrical HOUSING WITH CONE RINGS ’at the end, an annular groove is made at the junction of the rings 30 along the outer perimeter, in which a profiled rubber ring is laid.

На фиг. 1 изображена предлагаемая оправка, продольный разрез, на фиг.2 разрез А-А на фиг. 1.In FIG. 1 shows the proposed mandrel, a longitudinal section, in FIG. 2 a section aa in FIG. 1.

Оправка состоит из цилиндрического корпуса 1 с конусным концом 2, на который один за другим надеты два конусных кольца 3 и 4, закрепленные на конусном конце 2 торцовой кольцевой шайбой 5 с помощью затяжных болтов б. На торцовом конусном кольце 4, в месте стыка с конусным кольцом 3 по внешнему периметру выполнена кольцевая выточка 7, в которой.установлено профилированное кольцо 8. На оправку намотана труба 9, например, стеклопластиковая.The mandrel consists of a cylindrical body 1 with a tapered end 2, on which two conical rings 3 and 4 are mounted one after the other, fixed to the tapered end 2 by an end ring washer 5 with the help of tightening bolts b. On the end conical ring 4, at the junction with the conical ring 3, an annular recess 7 is made along the outer perimeter, in which a profiled ring 8 is installed. A pipe 9, for example, fiberglass, is wound on the mandrel.

Для облегчения демонтажа конусныц кольца 3 и 4 имеют продольные радиальные вырезы 10.To facilitate the dismantling of the conical rings 3 and 4 have longitudinal radial cuts 10.

Предлагаемое устройство работает следующим образом.The proposed device operates as follows.

Перед намоткой стеклопластиковой, трубы или соединительной детали с раструбным соединением производят сборку оправки. Одевают на конусный конец 2 конусное кольцо 3, а затем конусное кольцо 4 с установленным в его колыфвой выточке 7 профилированным резиновым кольцом 8 и закрепляют сборку торцовой кольцевой шайбой 5 с помощью болтов б. Затем устанавливают смонтированную оправку' на устройство для изготовления труб методом намотки и производят намотку.Before winding fiberglass, pipe or connecting parts with a bell-shaped joint, the mandrel is assembled. Put a taper ring 3 on the tapered end 2, and then a tapered ring 4 with a profiled rubber ring 8 installed in its kolifva groove 7 and fix the assembly with the end ring washer 5 using bolts b. Then, the mounted mandrel is mounted on the device for manufacturing pipes by winding and winding.

После намотки оправку снимают с устройства и демонтируют. Вывинчивают болты б, снимают кольцевую шайбу 5 и вынимают торцовое конусное кольцо 4. Профилированное резиновое кольцо 8, которое находилось в кольцевой выточке 7 торцового конусного кольца 4, остается в образованной им профилированной кольцевой канавке раструба стеклопластиковой трубы 9, но 15 так как оно резиновое, легко деформируется и тоже вынимается, а за ним вынимается и конусное кольцо 3.After winding, the mandrel is removed from the device and dismantled. Unscrew the bolts b, remove the annular washer 5 and remove the end conical ring 4. The profiled rubber ring 8, which was in the annular groove 7 of the end conical ring 4, remains in the profiled annular groove of the bell of the fiberglass pipe 9 formed by it, but 15 since it is rubber, it is easily deformed and is also taken out, and a conical ring 3 is taken out after it.

Стеклопластиковая труба 9 (или сое-20 динительная деталь) с образованным на ее конце профилированным раструбом с оправки снимается, и производится подкотовка к следующей на-·, мотке.The fiberglass pipe 9 (or joint-20 extension piece) with the profiled bell formed at its end is removed from the mandrel and underflooding is made to the next winding.

Технико-экономический эффект предлагаемой конструкции заключается в ее простоте, возможности применения в разных оправках с разъемными или разборными цилиндрическими 5 корпусами и легкой замене профилированного резинового кольца.The technical and economic effect of the proposed design lies in its simplicity, the possibility of using it in different mandrels with detachable or collapsible cylindrical 5 cases and easy replacement of the profiled rubber ring.

Claims

The invention relates to the processing of polymeric materials by winding and can be used in various ways in the national economy in the fabrication of various pipes and connections of sesibHux parts. A known mandrel for the manufacture of curved pipes, representing; is a rubber mandrel, deformed by axial flow in order to detach it from the product surface. i The disadvantage of this mandrel is the poor quality of manufactured ftIX pipes. The known mandrel for winding the pipe-side part of the pipe / containing a detachable cylindrical body with cone rings on the end of And. However, such a construction of a known mandrel does not provide a socket, on the inner surface of which there are profiled depths. The purpose of the invention is forming during the winding of a shaped socket. This goal is achieved by having a sieve containing a split cylindrical body with tapered SPINS at the end, at the junction of the rings along the outer perimeter there is a ring groove in which a sold rubber ring is laid. FIG. 1 shows the proposed mandrel, a longitudinal section; in FIG. 2, section A-A in FIG. 1. The mandrel consists of a cylindrical body 1 with a tapered end 2, on which two conical rings 3 and 4 are put on one after the other, fixed on the conical end of 2 tons with a 5-ring washer 5 using tightening bolts 6. On the end conical ring 4 the junction with a tapered ring 3 along the outer perimeter is made of an annular rim 7, in which a profiled ring 8 is installed. A pipe 9, for example, fiberglass plastic is wound on it. To facilitate the dismantling, the tapered rings 3 and 4 have longitudinal radial 10. The proposed device works in a cim-pattern. Before winding fiberglass. the pipe or socket part with bell-shaped joint assembles the mandrel. Put on the tapered end 2 the tapered ring 3, and then the tapered ring 4 with the profiled rubber ring 8 installed in its notch 7 and fix the assembly with an end ring washer 5 with the help of bolts b. Then install the mounted mandrel on the device for the manufacture of tr by the method of winding and winding is performed. After winding, the mandrel is removed from the device and removed. The bolts b are removed, the annular washer 5 is removed and the end cone ring 4 is removed. The profiled rubber ring 8, which was in the annular recess 7 of the cone 4, remains in the fiberglass pipe 9 formed by it, and because rubber, easily deformed and also removed, and behind it the conical ring 3 is also removed. The glass-fiber pipe 9 (or the dynamic part) with the shaped bell formed at its end is removed from the mandrel, and produced ION to the next wound. The technical and economic effect of the proposed design lies in its simplicity, the possibility of using it in different mandrels with detachable or collapsible cylindrical housings and easy replacement of the shaped rubber ring. Claim for winding pipes made of polymeric materials, including a detachable cylindrical body with tapered rings at the end, characterized in that, in order to form when winding a profiled socket, at the junction of the rings along the outer perimeter there is an annular groove in which a profiled rubber is laid ring.
