Description
СПОСОБ ИЗГОТОВЛЕНИЯ ПОЛЫХ ИЗДЕЛИЙ METHOD OF MANUFACTURING HOLLOW PRODUCTS
Изобретение относитс к области получени изделий ирессоваиием из труднодеформируемых материалов.The invention relates to the field of obtaining products and pressing them from hard-to-deform materials.
При известном способе прессовани труб или прутков металл течет в продольном направлении и структура выт нута параллельно оси трубы. В результате этого коэффициент анизотропии механических свойств у прессованных труб в 1,5-3 раза выше, чем у катанных .With the known method of pressing pipes or rods, the metal flows in the longitudinal direction and the structure is elongated parallel to the axis of the pipe. As a result, the anisotropy coefficient of the mechanical properties of extruded tubes is 1.5–3 times higher than that of rolled pipes.
Описываемый способ отличаетс от известных тем, что изделию в очаге деформации придают принудительное вращательное движение .The described method differs from the known ones in that a forced rotational movement is imparted to the product in the deformation zone.
Это снижает анизотропию механических свойств обрабатывае.мого материала.This reduces the anisotropy of the mechanical properties of the processed material.
Описываемый способ предусматривает изготовление изделий прессованием с принудительным вращением вьшрессовываемого издели , напрпмер, за счет выполнени матрицы с рабочим профилем в виде многозаходной гайки с глубиной резьбы, уменьшающейс доThe described method involves the manufacture of products by pressing with a forced rotation of the pressed product, naprmer, by making a die with a working profile in the form of a multiple thread nut with a thread depth decreasing to
О к выходу канала матрицы. В результате этого коэффициент анизотропии механических CBOiicTB прибли аетс к 1, так как из-за геликоидного истечени металла происходит выравнивание свойств металла в поперечном иAbout to the output channel of the matrix. As a result of this, the anisotropy coefficient of the mechanical CBOiicTB is close to 1, since, due to the helicoid flow of the metal, the properties of the metal in the transverse and
