Description
II
Изобретение относитс к обработке металлов давление.м, например к процессу гидростатического прессовани .The invention relates to the treatment of metals with pressure m., For example, a hydrostatic pressing process.
Известны конструкции пресс-штемпелей гидроэкструзионных прессов, на поверхности пресс-шайб которых закреплены уплотнительные эле.менты треугольного или круглого сечени из беррилиевой бронзы или меди, работающих по принципу некомпенсированной площади 1.Designs of press stamps of hydro-extrusion presses are known, on the surface of the press washers of which the sealing elements of triangular or circular section of berrillium bronze or copper are fixed, operating according to the principle of uncompensated area 1.
Однако уплотнени пресс-штемпелей известных конструкций обеспечивают надежную работу инструмента лищь в узком интервале рабочих давлений.However, press seals of known constructions ensure reliable operation of the tool in a narrow range of operating pressures.
Известен также пресс-щте.мпель гидро: )кструзионного пресса, состо щий из штока с прест-1лайбой, выполненной в форме стакана (- конусны.ми стенка.ми, на участке меньшего диаметра которой установлены уплотни гсльные кольца 2.Also known is a press shtemp. Hydro:) of a extrusion press consisting of a stem with a front-1 tube, made in the form of a cup (- tapered walls, with sealing rings 2 installed on the smaller diameter section.
Однако при достижении величины рабоMi-Kj давлени жидкости до 25-30 кбар. ко.и,новой зазор между стенками контейнера и поверхностью пресс-шайбы ,вследствие окпанани деформации сжати преес-итемntM ,i от деформации раст жени внутреннейHowever, when the value of the Mi-Kj fluid pressure reaches 25-30 kbar. k.i., a new gap between the walls of the container and the surface of the press washer, due to the compression deformation of the material, M, i from internal deformation
втулки контейнера, становитс настолько велик , что происходит прорыв рабочей жидкости в надштемпельное пространство. Это приводит к нестабильности процесса и снижению качества пресс-изделий либо к полному прекращению процесса.the hub of the container becomes so large that a breakthrough of the working fluid into the above-stamped space occurs. This leads to instability of the process and a decrease in the quality of press products or to the complete cessation of the process.
Цель изобретени - повыщение надежности работы уплотнений.The purpose of the invention is to increase the reliability of the seals.
Дл этого в стенках стакана с торцовой стороны параллельно оси пресс-шайбы и равномерно по периметру выполнены прорези на длине, равной 0,2-0,3 ее высоты.For this, in the walls of the glass from the front side parallel to the axis of the press washer and evenly along the perimeter there are slots made at a length equal to 0.2-0.3 of its height.
Выполнение прорезей такой длины позволит увеличить возможную величину упругой деформации пресс-щайбы без уменьщени ее прочности.Making cuts of such length will allow increasing the possible value of the elastic deformation of the press plate without reducing its strength.
На чертеже изображен предлагаемый пресс-щтемпель.The drawing shows the proposed press shtempel.
Он содержит щток 1, пресс-шайбу в форме стакана с конусными стенками 2, в которых выполнены нрорези 3, уплотнительных колец 4.It contains the scraps 1, the press-washer in the form of a glass with conical walls 2, in which the cutters 3 are made, and the sealing rings 4.
Пресс-штемпель изображен в рабочем положении в корпусе внутренней втулки контейнера 5, в котором налита рабоча жидкость . Высота уплотнений Нг, а длина проThe ram is depicted in the working position in the housing of the inner sleeve of the container 5, in which the working fluid is poured. Seal height Ng, and length about
