Изобретение относитс к области обработки металлов давлением.This invention relates to the field of metal forming.
Известен способ прессовани труб путем выдавливани материала заготовки в кольцевой зазор, образованный калибрующим отверстием матрицы и иглой, перемещаемой в сторону, противоположную истечению материала заготовки.There is a known method of pressing tubes by squeezing the material of the blank into an annular gap formed by a calibrating hole of the die and a needle moved in the direction opposite to the outflow of the material of the blank.
С целью выравнивани структуры по сечению издели за счет уменьшени вли ни сдвиговых деформаций частиц металла относительно друг друга на поверхности, контактирующей с иглой, по предлагаемому способу скорость перемещени иглы задают больше скорости истечени материала заготовки.In order to align the structure over the cross section of the product by reducing the effect of shear deformations of metal particles relative to each other on the surface in contact with the needle, according to the proposed method, the speed of movement of the needle sets the flow rate of the workpiece material more.
На чертеже показана схема пр мого прессовани по предлагаемому способу.The drawing shows a direct compression scheme for the proposed method.
Заготовка 1 помещаетс в контейнер 2. Под действием силы Р пуансон 3 и пресс-щтемпель 4 перемещают металл в кольцевой зазор между иглой 5 и калибрующим очком матрицы 6 со скоростью 1/2- Игле в процессе истечени материала заготовки сообщают перемещение со скоростью Vi, причем Vl дл выравнивани структуры должна быть больще Vz. При этом происходит выравнивание деформаций и устранение неравномерностейThe workpiece 1 is placed in the container 2. Under the action of the force P, the punch 3 and the press shtampel 4 move the metal into the annular gap between the needle 5 and the calibrating point of the matrix 6 at a rate of 1/2. The needle during the outflow of the workpiece material reports movement at speed Vi. Vl to align the structure must be greater than Vz. When this occurs, the alignment of deformations and the elimination of irregularities
структуры по сечению трубы, так как при перемещении трубной оправки вверх по внутренней поверхности трубы и заготовки действуют силы трени , направленные вверх. Это же самое можно использовать в процессе обратного прессовани труб.structures along the section of the pipe, as when moving the tube mandrel up along the inner surface of the pipe and the workpiece, there are friction forces directed upwards. The same can be used in the process of reverse pressing of pipes.
Предмет изобретени Subject invention
Способ прессовани труб путем выдавливани материала заготовки в кольцевой зазор, образованный калибрующим отверстием матрицы и иглой, перемещаемой в сторону, противоположн}ю истечению материала заготовки , отличающийс тем, что, с целью выравнивани структуры по сечению издели , скорость перемещени иглы задают больше скорости истечени материала заготовки.The method of pressing the pipes by extruding the material of the workpiece into the annular gap formed by the calibrating hole of the matrix and the needle moved in the direction opposite to the outflow of the material of the workpiece, characterized in that, in order to align the structure over the section of the product, the speed of movement of the needle sets the speed of the material outflow blanks.
