Description

Translated fromRussian

Известны головки пресса дл  прессовани  металлических оболочек и труб с расноложеиными под углом друг к другу цилиндрическими или коническими каналами дл  прохождени  металла, содержащие матрицу и дори (или дорн с дорнодержателем). Такие головки сложно изготовл ть, кроме того, они недолговечны , так как нри термообработке и эксплуатации в иих возникают высокие концентрации напр жений. Дл  создани  равиомерного течени  металла к .матрице, обеснечивающего концентричность оболочки кабел , каналы дл  прохождени  металла имеют сложную ступенчатую конфигурацию с резкими нереходами .Press heads are known for pressing metal shells and pipes with cylindrical or conical channels at an angle to each other for the passage of metal containing matrix and dori (or mandrel with mandrel). Such heads are difficult to manufacture, and in addition, they are short-lived, since heat treatment and operation cause high concentrations of stresses in them. In order to create a raviomeric flow of metal to the matrix, which has cleansed the concentricity of the cable sheath, the channels for the passage of the metal have a complex, stepped configuration with abrupt non-transitions.

В результате высокого давлени  н температуры нзмен ете  форма каналов и увеличиваетс  разностеимость оболочки.As a result of high pressure and temperature, the shape of the channels is replaced and the sheath difference increases.

В предлагаемой головке, с целью увеличени  срока службы и прочности, а также обеспечени  универсальности, указанные каналы образованы пр молинейными образующими с направл ющими в виде гладких выпуклых кривых, а дорн (или дорнодержатель) в зоне указанных каналов выполнен со срезами на боковой новерхпости на величину 0,01-0,5 его радиуса.In the proposed head, in order to increase durability and strength, as well as to ensure versatility, these channels are formed by straight lines forming guides in the form of smooth convex curves, and the mandrel (or long holder) in the area of said channels is cut with side upperness by 0.01-0.5 of its radius.

йены цилиидрическими, а дорнодержатель 2- со срезами ла боковой поверхиости. Величина этого среза составл ет 0,01-0,5 от величины образующего его раднуса. При нрессовании оболочек больщего диаметра, нанример болос 20 мм, может включатьс  дроссельное колыш и профилированна  шайба с овальным отверстием . Металл из контейнера иостунает в Г ловку но каналу /, обтекает дориодержатель 2, измен ет ианравленне на 90 и, пройд  через профилированную щайбу н дроссельное кольцо , формуетс  в оболочку, размеры которой задаютс  дорном 3 нматрицей 4.the yens are ciliidric, and the doron holder is 2- with sections on the lateral surface. The magnitude of this slice is 0.01-0.5 of that of the radnus that forms it. During the pressing of shells of a larger diameter, a bolus of 20 mm may include a throttle rod and a shaped washer with an oval hole. The metal from the container, in the direction of the channel I, flows around the doroyerer 2, changes and engraves by 90 and, after passing through the profiled tongue onto the throttle ring, is molded into a shell, the dimensions of which are set by the mandrel 3 at 4.

Расточки в корпусе предлагаемой головки в отличие от известных представл ют сочетание двух цилиндрических или конической и цилиндрической новерхиостей со взанмно иернендикул риыми ос ми, а си.мметрирование потоков металла выполн етс  за счет описаииой формы виутреинего неметаллоемкого сменного инструмента.The boreholes in the body of the proposed head, in contrast to the known ones, represent a combination of two cylindrical or conical and cylindrical overheads with up-and-up alternate axes, and symmetric measurement of metal flows is performed by describing the shape of a non-metal-replaceable replaceable tool.

Предмет изобретени Subject invention

Головка пресса дл  прессоваип  металлических , папример алю.миииевых, оболочек и труб с расиоложепиыми под углом друг к другу цилиндрическими или коническими каиалами дл  входа и выхода металла, содержаща  матрицу н дори (или дорн с дорподержателем ), отличающа с  тем, что. с целью увеличеин  срока службы головки и ее прочности, а также обеспечени  ее универсальности, указаппые каналы образованы пр молинейными образующими с направл юш,ими в виде гладких выпуклых кривых, а дорн (или дорнодержатель ) в зоне указанных каналов выполнен со срезами на боковой поверхности на величипу 0,01-0,5 его радиуса.A press head for pressing metal, for example, aluminum, shells and pipes with cylindrical or conical angles that are different at an angle to each other for the metal inlet and outlet, containing a matrix n dori (or mandrel with a dorpo holder), characterized in that. In order to increase the durability of the head and its durability, as well as to ensure its versatility, the untrained channels are formed by straight lines forming with directional ush, they are in the form of smooth convex curves, and the mandrel (or dorodholder) in the area of the said channels is cut with side sections on magnitude 0.01-0.5 of its radius.
