Description
ПРИЖИМ дл ГИБКИ ТРУБ ПРЯМОУГОЛЬНОГО СЕЧЕНИЯCLUTCH FOR BENDING PIPES OF RECTANGULAR SECTION
РГзвестны прижимы, дл гибки труб пр моугольного сечени . Они содержат корпус, состо щий из двух симметричных деталей, кажда из которых имеет паз с расположенной в нем поворотной вставкой.Clamps are known for bending rectangular tubes. They contain a body consisting of two symmetrical parts, each of which has a groove with a rotatable insert located therein.
Предлагаемый прижим отличаетс от известных тем, что паз в нем выполнен кольцевым , а поворотна вставка - из эластичного материала. Этот прижим осуш;ествл ет посто нное осевое сжатие боковых стенок трубы в процессе гпба н таким образом позвол ет избежать гофрообразовани волновода.The proposed clamp differs from the known ones in that the groove in it is made annular and the rotary insert is made of an elastic material. This pressing dehydrates; the constant axial compression of the side walls of the pipe during the gpba process is thus permitted to avoid corrugation of the waveguide.
Описываемый прижим изображен на чертеже .The described clamp is shown in the drawing.
Корнус прижима включает в себ две симметричиые детали У в виде дисков, кажда из которых имеет кольцевой паз а с расположеппой в пем поворотиой вставкой 2. Вставка изготовлепа из полиамида или другого эластичпого материала и контактирует с заготовкой 3 в процессе гиба.The Cornus of the clamp includes two symmetrical parts Y in the form of discs, each of which has an annular groove and is located in the letter insert 2. The insert is made of polyamide or other elastic material and contacts the workpiece 3 during the bending process.
Предмет изобретени Subject invention
Прижим дл гибки труб пр моугольного сечени (волноводов), содержащий корпус, выполненный из двух си.мметричиых деталей, кажда из которых имеет паз с расположеипой в нем поворотиой вставкой, отличающийс тем, что, с целью осуществленн поето нного осевого сжати боковых стеиок трубы в процессе гпба, иаз в нем выиолиеи кольцевым , а новоротиа вставка - из эластпчиого материала.A clamp for bending rectangular section tubes (waveguides), comprising a body made of two symmetric parts, each of which has a groove with a rotation insert in it, characterized in that, in order to carry out the axial compression of the lateral steioc pipes in The GPB process, which is enclosed in it, is annular, and the Novorovia insert is made of an elastomeric material.
