Изобретение относитс к электротехнике , преимущественно к кабельной технике , а именно к установкам дл наложени экструзией изол ции на провода К кабели.The invention relates to electrical engineering, primarily to cable technology, namely to installations for the extrusion of insulation onto wires to cables.
Известны установки, предназначенные дл переработки высокомолекул рных со ,единений при наложении изол ции или защитных покрытий кабелей и проводов способом выдавливани (экструдировани ) . В таких установках наложение материалов , например резиновых смесей, осуществл етс в пластическом состо нии , которое достигаетс как нагревом самого перерабатываемого материала, так и нагревом цилиндров черв чных прессов.Installations are known that are designed to process high molecular weight compounds when applying insulation or protective coatings on cables and wires by extrusion. In such installations, the application of materials, such as rubber compounds, is carried out in a plastic state, which is achieved by heating the material itself and heating the cylinders of the worm presses.
Дл такой конструкции пресса при посто нных оборотах черв ка и посто нной пластичности материала производительность будет посто нной 11J.For such a press design, at constant revolutions of the screw and constant plasticity of the material, the productivity will be constant 11J.
При изменении температуры нагрева перерабатываемого материала происходит изменение его пластичности, что приводит к изменению производительности, а соответственно и колебани м наружного диаметра кабельного издели .When the heating temperature of the material being processed is changed, its plasticity changes, which leads to a change in productivity and, accordingly, fluctuations in the outer diameter of the cable product.
Наиболее близким к изобретению по достигаемому результату вл етс устройство стабилизации диаметра изолированного провода, содержащее датчик отклонени диаметра, датчик скорости, интегратор и блок произвадени , входы которого подключены к упом нутым датчикам , а выход - к интегратору. В таком устрюйстве стабилизаци диаметра изол ции осуществл етс с помощью интегратора и блока произведени , в котором сигнал, пропорциональный отклонению диаметра, умножаетс на сигнал, пропорциональный лингйной скорости движени провода 2.The closest to the invention in terms of the achieved result is a device for stabilizing the diameter of insulated wire, comprising a diameter deviation sensor, a speed sensor, an integrator and a production unit, the inputs of which are connected to said sensors and the output to an integrator. In such a device, the isolation diameter is stabilized using an integrator and a product block, in which a signal proportional to the diameter deviation is multiplied by a signal proportional to the lingual speed of the wire 2.
Недостатком раббты известного устройства при использовании в агрегатах непрерывной вулканизации вл етс его низкое быстродействие. Это вызвано тем, что изменение производительности пресса (например за счет изменени пластичности) обуславливает изменение .диаметра издели , при этом контроль диаметра может быть осуществлен с запаздыванием во времени лишь на выходе вулканизационной трубы, длина которой составл ет 100 м и более.The disadvantage of a known device when used in continuous vulcanization units is its low speed. This is because a change in press capacity (e.g. due to a change in plasticity) causes a change in the diameter of the product, and the diameter can be controlled with a time lag only at the exit of the vulcanization pipe, which is 100 meters long or more.
Целью изобретени вл етс стабилизаци произво/1ительности черв чного .пресса при изменении пластичности перерабатываемого высокомолекул рного материала и повышение качества выпускаемой продукции.The aim of the invention is to stabilize the production of the screw press when the plasticity of the processed high molecular weight material changes and to improve the quality of the output.
