Description

(5) УСТРОЙСТВО ДЛЯ ИЗГОТОВЛЕНИЯ полых ПРОФИЛЕЙ из ПОЛИМЕРНЫХ МАТЕРИАЛОВ(5) DEVICE FOR MANUFACTURING HALF PROFILE OF POLYMER MATERIALS

Известно устройство дл  изготовлени  полых профилей из полимерных материалов, содержащее установленный с зазором относительно формующей головки экструдера охлаждаемый калибрующий дорн.A device for manufacturing hollow profiles made of polymeric materials is known, which comprises a calibrating mandrel cooled with a gap relative to the extruder forming head.

С целью изготовлени  полых профилей переменного сечени  калибрующий . дорн снабжен сообщающимис  каналами дл  подвода сжатого воздуха в зазор между дорном и головкой и в кольцевую канавку, расположенную на калибрующей поверхности.у конца дорна.In order to produce hollow profiles of variable cross section, calibrating. The mandrel is provided with communicating channels for supplying compressed air into the gap between the mandrel and the head and into the annular groove located on the calibrating surface of the end of the mandrel.

На чертеже изображена конструкци  предлагаемого устройства.The drawing shows the design of the proposed device.

Устройство состоит из калибрующего дорна 1, установленного с зазором 2 относительно формующей головки экструдера 3.The device consists of a calibrating mandrel 1, installed with a gap of 2 relative to the forming head of the extruder 3.

Калибрующий дорн снабжен каналами k дл  подвода охлаждающего агента, распредел ющей вставкой 5 каналом б дл  удалени  охлаждающего агента, каналом 7 дл  подвода раздувающего агента, распределительной камерой 8, отверсти ми 9 в боковой поверхности, канавкой 10, расположенной на калибрующей поверхности в конце дорна, обратными каналами 11 и запирающими поверхност ми 2.The sizing mandrel is provided with channels k for supplying a cooling agent, distributing the insert 5 with channel b for removing the cooling agent, channel 7 for supplying the blowing agent, distribution chamber 8, openings 9 in the side surface, groove 10 located on the calibrating surface at the end of the mandrel, return channels 11 and locking surfaces 2.

Устройство работает следующим образом .The device works as follows.

Первоначальна  заправка .экструдируемой заготовки на калибрующий дорн производитс  так же, как и при работ с калибрующими дорнами существующих конструкций: экструдируемую заготовку вручную расшир ют и прит гивают через дорн, присоедин ют затем к т нущему устройству (на чертеже не пдказано ) и начинают процесс калибровани  полого профил  по внутренней поверхности . При этом дл  охлаждени  калибрующего дорна и профил , обжимающего дорн, внутрь последнего, например , по каналу подают охлаждаThe initial charging of the extruded billet to the calibrating mandrel is carried out in the same way as when working with calibrating mandrels of existing structures: the extruded billet is manually expanded and pulled through the mandrel, then attached to the host device (not shown) and start the calibration process hollow profile on the inner surface. At the same time, in order to cool the calibrating mandrel and the profile compressing the mandrel, inside the latter, for example, cooling channel is supplied through the channel.
