Abstract

The present invention relates to a device for stripping the length of the outer insulation of cables having a circular cross-section and to a method of using the device. In order to avoid the problems of known stripping devices which are not self-centring, a stripping device is provided which comprises cutters 1, having curved edges 1b, and being arranged in pairs, each pair of cutters being movable in a radial groove of a holder 2. Control cams 3 are provided which have cam grooves 3a in the form of curved slots. The slots 3a serve to move the cutters 1 by means of guide pins 1a provided on each cutter. In use, relative rotation between the cam plates 3 and the holder 2 causes the cutters 1 to move in the radial grooves of the holder 2, whereby the cutters 1 cut into the outer insulation of a circular cable which has previously been inserted into the device along the axis of the device. The cam slots may follow a logarithmic spiral. <IMAGE>

Каждый из диаметральных пазов диска выполнен на одной из его торцовых поверхностей перпендикул рно друг к другу и имеет одинаковую глубину, равную половине высоты диска. В пазах диска 6 ножи 1 установлены попарно. Плоскость f ножей представл ет собой одну плоскость . Диск 6 с ножами 1 и кулачки А установлены в цилиндрическом корпусе 7. Кулачки жестко св заны с корпусом 7 винтами 8, а диск 2 снабжен приводным рычагом 9 и установлен в корпусе с возможностью поворота. На корпусе 7 установлена скоба 1-0 с регулировочным винтом 11 и нанесена шкала 12 размеров с одной его торцовой стороны, а с другой установ лена крышка 13- Кабель 14 устанавливаетс  в центральное отверстие устройства . Устройство работает следующим об-разом . При перемещении рычага 9 поворачи ваетс  диск б с ножами 1. При этом пальцы 2 ножей 1 следуют по пазам 5 кулачков k и описывают по периметру кабел  , соответствующую фо|эме пазов кулачков. В результате этого пластмассова  оболочка кабел  Н разрезаетс . После определени  размера разреза путем измерени  или расчета можно установить величину перемещени  с помощью скобы 10. Удаленный синтетический слой оболочки равен толщине сло  между полным нару ным диаметром кабел  D и полигональным контуром, ограниченным дугами полученным в результате среза D| (фиг. k}. 64 Предлагаемое изобретение имеет более простую конструкцию, меньшие габариты по сравнению с известной, а его применение позвол ет срезать оболочку без повреждени  изол ции жил, наход щихс  внутри кабел . Формула изобретени  1.Устройство дл  удалени  изол ции с кабел , содержащее цилиндрический корпус с руко ткой, диск с центральным отверстием дл  захода кaьeл  установленный в корпусе и несущий ножи с выступами и с режущей кромкой, выполненной по дуге, кулачок с пазами, в которых расположены выступы ножей, отличающеес  тем, что, с целью упрощени  конструкции, устройство содержит скобу с элементами фиксации, установленную на корпусе, и второй кулачок , диск выполнен с двум  пазами одинаковой глубины, равной половине высоты диска, каждый из которых расположен на одной из торцовых поверхностей , перпендикул рно друг к другу , при этом ножи установлены попарно в пазах диска, а диск установлен между кулачками. The device contains knives 1 with fingers 2 and a knife blade 3 two cam 3. 9 ka with grooves 5i made along an arc of a logarithmic spiral. A disk 6 with knives 1 mounted in its diametrical grooves is located between the cams 4. Each of the diametrical grooves of the disk is made perpendicular to one another on one of its end surfaces and has the same depth equal to half the disk height. In the slots of the disk 6, the knives 1 are installed in pairs. The plane f of the knives is one plane. A disk 6 with knives 1 and cams A are mounted in a cylindrical housing 7.
