Description

Изобретение относитс  к переработке полимерных материалов и может быть использовано в лини х дл  производства труб экструзионным методо Известно устройство дл  калибровани  труб, включающее калибрующую втулку и рубашку, образующие между собой канал дл  хлада| ента, и штуце ры подачи и слива хладагента 1. Недостатком устройства  вл етс  невысокое качество получаемых трубза счет налипани  экструдата на сте ки калибрующей втулки. Целью изобретени   вл етг  повышение качества труб путем исключени налипани  экструдата на стенки калибрующей втулки. Указанна  цель достигаетс  тем, что устройство дл  калибровани  экструдируемых труб из пластмасс, вкл чающее калибрующую втулку и рубашку образующие между собой канал дл  хладагента, и штуцеры подачи и слив хладагента, снабжено кольцевой камерой , установленной на, входном участке калибрующей втулки соосно рубашке, снаружи ее, а между торцами калибрующей втулки и рубсиики образована кольцева  щель, соедин юща камеру с каналом дл  хладагента. На чертеже представлена схема устройства дл  калибровани  экструдируемых труб из пластмасс, общий вид. Устройство включает калибрующую втулку 1, рубашку 2, скрепленные друг с другом при помощи гайки 3 и образующие между собой канал 4 дл  хладагента. Штуцер 5 предназначен дл  подачи хладагента в кольцевую камеру 6, установленную на начгшьном участке калибрующей втулки 1 соосно рубашке, снаружи ее, и соединенную с каналом 4 дл  хладагента кольцевой щелью 7, образованной торцами кгтибрующей втулки 1 и рубашки 2, Отверстие 8 предназначено дл  подачи воздуха внутрь трубы, а штуцер 9 дл  слива хладагента. Устройство работает следующим образом . Хладагент, через штуцер 5 подаетс  в кольцевую камеру 6, далее через кольцевую щель 7 поступает в канал 4, проходит через калибрующую втулку 1 и сливаетс  через штуцер 9. Выход ща  из экструзионной головки (на чертеже не показана) трубчата  заготовка 10, прижимаетс  к поверхности калибрующей втулки 1 воздухомпоступающим через отверстие .8.The invention relates to the processing of polymeric materials and can be used in the lines for the production of pipes by extrusion method. A device for calibrating pipes, including a calibration sleeve and a jacket, forming between them a channel for cooling | The supply and discharge connections of the refrigerant 1. A disadvantage of the device is the low quality of the pipe produced by sticking the extrudate onto the stack of the gage sleeve. The aim of the invention is to improve the quality of pipes by eliminating the adhesion of the extrudate to the walls of the gage sleeve. This goal is achieved by having a device for calibrating extruded plastic pipes, including a calibrating sleeve and a jacket, forming a coolant channel between them, and fittings for supplying and draining the coolant, is provided with an annular chamber mounted on the inlet section of the calibrating sleeve coaxially with the jacket and an annular gap is formed between the ends of the calibrating sleeve and the rubsiyki connecting the chamber with the channel for the refrigerant. The drawing shows a diagram of a device for calibrating extruded plastic pipes, a general view. The device includes a calibrating sleeve 1, a jacket 2, fastened to each other by means of a nut 3 and forming between them a channel 4 for the refrigerant. The fitting 5 is designed to supply refrigerant to the annular chamber 6, mounted on the initial section of the calibrating sleeve 1 coaxially with the jacket, outside it, and connected to the refrigerant channel 4 with an annular gap 7 formed by the ends of the quilting sleeve 1 and the jacket 2. inside the pipe, and fitting 9 to drain the refrigerant. The device works as follows. The refrigerant through the nozzle 5 is fed into the annular chamber 6, then through the annular slot 7 enters the channel 4, passes through the calibrating sleeve 1 and is drained through the nozzle 9. The tubular billet 10 exits the extrusion head (not shown) and presses to the surface calibrating the sleeve 1 by air-passing through the hole .8.

Изобретение обеспечивает интенсивное охлажцение трубчатой заготовки на начальном участке калибрующей втулки, исключа  ее налипание на- стенки втулки,, повьЕйает качество изготовл емых труб.The invention provides intensive cooling of the tubular billet in the initial part of the gage sleeve, excluding its sticking of the bushing wall, which increases the quality of the pipes being made.
