Description
II
Изобретение относитс к области машиностроени и может быть использовано при изготовлении труб из полимерных материалов методом намотки.The invention relates to the field of mechanical engineering and can be used in the manufacture of pipes from polymeric materials by the winding method.
Известна оправка дл изготовлени труб, выполненна из образующих рабочую поверхность издели клиновых элементов 1).The known mandrel for the manufacture of pipes, made of wedge elements 1 forming the working surface of the product.
Однако конструкци такой оправки требует удалени одного из клиновых элементов дл ее разборки при съеме издели , что ведет к повреждению внутренней поверхности трубы в зоне контакта с удал емым клином.However, the design of such a mandrel requires the removal of one of the wedge elements for disassembling during removal of the product, which leads to damage to the inner surface of the pipe in the zone of contact with the wedge to be removed.
Известна также оправка, состо ща из разрезной цилиндрической обечайки, установленной в пазах концевых элементов (2J.A mandrel is also known, consisting of a split cylindrical shell installed in the grooves of the end members (2J.
Однако эта оправка не обеспечивает достаточной жесткости и требует усили дл выема обечайки при съеме издели после отверждени .However, this mandrel does not provide sufficient rigidity and requires force to remove the shell when removing the product after curing.
Целью изобретени вл етс увеличение жесткости оправки и облегчение съема готового издели .The aim of the invention is to increase the rigidity of the mandrel and facilitate the removal of the finished product.
Указанна цель достигаетс тем, что оправка, состо ща из разрезной цилиндрической обечайки, установленной в пазахThis goal is achieved by the fact that the mandrel consisting of a split cylindrical shell installed in the grooves
концевых элементов, снабжена двум клиновыми элементами, один из которых установлен в продольном вырезе обечайки, образу с ней рабочую поверхность, а другой - в полости обечайки враспор с пер5 вым.the end elements are provided with two wedge elements, one of which is installed in the longitudinal notch of the shell, forming a working surface with it, and the other in the cavity of the shell of the first half.
На фиг. 1 схематично изображена предлагаема оправка дл изготовлени труб из полимерных материалов методом намотки; на фиг. 2 - разрез А-А на фиг. I; на фиг. 3 - разрез Б-БFIG. 1 schematically shows the proposed mandrel for the manufacture of pipes from polymeric materials by the winding method; in fig. 2 shows section A-A in FIG. I; in fig. 3 - section BB
10 на фиг. I.10 in FIG. I.
Оправка состоит из разрезной цилиндрической обечайки 1 и концевых элементов 2 и двух клиновых элементов; одни из них - клин 3 установлен в продольном вырезе обечайки I, образу с последней рабочую поверхность дл формовани , а другой - клин 4 установлен в полости обечайки враспор с клином 3.The mandrel consists of a split cylindrical shell 1 and end elements 2 and two wedge elements; one of them - a wedge 3 is installed in the longitudinal notch of the shell I, forming a working surface for molding with the latter, and the other - a wedge 4 is installed in the shell cavity with a wedge 3.
Работа устройства осуществл етс следующим образом.The operation of the device is as follows.
20 Оправка после сборки с концевыми элементами устанавливаетс на намоточном станке.20 A mandrel after assembly with end pieces is mounted on a winding machine.
