Description

Известные способы и инструменты дл  наложени  металлических оболочек на кабели позвол ют получать оболочки диаметром от 5 мм и более при минимальной толщине стенки равной 0,5-1,0 мм. Наложение на кабели металлических оболочек меньшего диаметра с толщиной, стенки 0,1-0,3 мм при помощи дорнов и матриц известных конструкций не дает положительных результатов.The known methods and tools for imposing metal sheaths on cables make it possible to obtain shells with a diameter of 5 mm or more with a minimum wall thickness of 0.5-1.0 mm. The imposition of metal shells of smaller diameter and thickness on the cables, walls of 0.1-0.3 mm with the aid of mandrels and matrices of known structures does not give positive results.

Предлагаемый инструмент позвол ет получать оболочки с толщиной стенки 0,1-0,3 мм, так как дорн и матрица выполнены раздельно и при монтаже в прессовой головке их устанавливают на общей опоре.The proposed tool allows obtaining shells with a wall thickness of 0.1-0.3 mm, since the mandrel and the die are made separately and, when mounted in a press head, are mounted on a common support.

Проволока или кабель подаютс  через вводной полый болт и втулку с опорным фланцем в центральный канал дорна. Давлением прессуемого металла втулка прижимаетс  к корпЗТу дорна. Дл  симметричного поступлени  металла в камеру сварки в корпусе дорна имеютс  четыре канала. Дорн и матрицы опираютс  на упорный болт, закрепленный в переднем патроне корпуса головки. Обогрев прессовой головки осуществл етс  электронагревател ми сопротивлени .A wire or cable is fed through an insertion hollow bolt and sleeve with a support flange into the central channel of the mandrel. By pressing the pressed metal, the sleeve presses against the core of the mandrel. For the symmetric entry of metal into the welding chamber in the body of the mandrel, there are four channels. The mandrel and dies are supported by a stop bolt secured in the front chuck of the head housing. The pressing head is heated by electric resistance heaters.

Нагрета  алюминиева  заготовка загружаетс  в головку. Под давлением , передаваемым на металл пуансоном, алюминий заполн ет полость головки и по каналам дорна попадает в камеру сварки, где свариваетс  вокруг носка дорна и в виде оболочки подаетс  через кольцевоН зазор, образованный носком дорна и матрицей.The heated aluminum billet is loaded into the die. Under pressure transferred to the metal by a punch, aluminum fills the cavity of the head and through the channels of the mandrel enters the welding chamber, where it is welded around the toe of the mandrel and in the form of a shell is fed through an annular gap formed by the toe of the mandrel and the die.

При этом давление металла у входа в полость головки значительно выще, чем в последующих ее камерах, и падает до минимума на выходе готовой оболочки, что исключает расклинивание дорна и матрицы.The pressure of the metal at the entrance to the cavity of the head is much higher than in its subsequent chambers, and drops to a minimum at the exit of the finished casing, which excludes wedging of the mandrel and the matrix.

Предмет изобретени Subject invention

Инструмент дл  наложени  тонкостенных йеталлических оболочек на провода, кабели и дл  изготовлени  тонкостенных труб, отличающийс  тем, .что, с целью получени  металличес-ких оболочек с меньшим отклонением по толщине их, дорн и матрица опираютс  в прессовой головке на общую опору, в результате чего в любой момент прессовани  давление металла перед входом в капалы корпуса дорна выше , чем на последующих участках металла, что исключает расклинивапие дорна и матрицы.A tool for imposing thin-walled metal shells on wires, cables and for making thin-walled pipes, characterized in that, in order to obtain metallic shells with a smaller variation in thickness, the mandrel and die are supported in the press head on a common support, resulting in At any moment of pressing, the pressure of the metal before entering the canals of the mandrel body is higher than in subsequent metal sections, which excludes wedge mandrel and dies.
