Description
Изобретение относитс к электротехнике, в частности к кабельной технике.The invention relates to electrical engineering, in particular to cable technology.
Целью изобретение вл етс обеспечение равномерного нагрева экструзионной головки, необходимого дл качественного наложени экструдируемой массы при снижении расхода электрической энергии за счет уменьшени тепловых потерь.The aim of the invention is to ensure uniform heating of the extrusion head, necessary for the qualitative imposition of the extrudable mass while reducing the consumption of electrical energy by reducing heat loss.
На чертеже изображена экструзионна головка.The drawing shows an extrusion head.
Экструзионна головка содержит коническую втулку 1 с фасонными пазами, котора садитс в отверстие корпуса 2 и прижимаетс гайкой 3. В центральном отверстии втулки 1 находитс дорнодержатель 4 с дор- ном 5. В передней части к торцу корпуса 1 прижата гайкой б матрица 7, имеюща возможность центрировани (благодар зазору между цилиндрической частью корпуса и матрицей) посредством болтов 8. Пластическа масса из экструдера через фланец корпуса 2 по фасонным пазам конической втулки 1 поступает в зону наложени между дорном 5 и матрицей 7 и накладываетс на жилу, непрерывно подаваемую через центральное отверстие дорнодержател 4The extrusion head contains a conical sleeve 1 with shaped grooves, which fits into the opening of the housing 2 and is pressed by the nut 3. In the central opening of the sleeve 1 there is a snap-holder 4 with a mandrel 5. In the front part, the die 7 is pressed against the end of the housing 1 with a nut centering (due to the gap between the cylindrical part of the housing and the die) by means of bolts 8. The plastic mass from the extruder through the flange of the housing 2 along the shaped grooves of the conical sleeve 1 enters the overlap zone between the mandrel 5 and the die 7 and the overlay vaets per wire is continuously fed through the central opening 4 dornoderzhatel

Втулка 10 преп тствует потере тепла из дорнодержател 4, создает дополнительную зону дл подогрева жилы и одновременно вл етс дл нее направл ющей. На наружной поверхности корпуса 2 имеетс теплоизол ци 11. Термопара 12 служит дл контрол и регулировани температуры нагрева головки . 0and a mandrel 5. A heater 9 is located in the inner part of the arch holder. The sleeve 10 prevents heat loss from the arch holder 4, creates an additional zone for heating the core and at the same time is a guide for it. On the outer surface of the housing 2 there is thermal insulation 11. Thermocouple 12 serves to control and regulate the temperature of the heating head. 0
