Description
(54) СОСТАВНАЯ ОПРАВКА ДЛЯ РОТАЦИОЫИО:(54) COMPOSITION ROTATING FOR ROTATIONIO:
ВЫДАВ/И-иЛАНИЯOUTLETS / YILEAS
бину, определ емую толщиной детали, включаетс продольна подача и начинаетс пр цесс выдавливани . Под действием усили продольной подачи подвижное кольцо 3 при помощи имеющегос на ней выступа Ьачинает перемещатьс по спиральному пазу корпуса 2, При этом возникает дополнительное тангенциальное усилие, передаваемое через элементы креплени на непрокатаннзто часть заготовки, которое и способствует по- лучению детали со спиральным расположением сварного шва.The bin, determined by the thickness of the part, turns on the longitudinal feed and starts the extrusion process. Under the action of the longitudinal feed force, the movable ring 3, using the protrusion B on it, starts to move along the spiral slot of the housing 2. This results in an additional tangential force transmitted through the fastening elements to the non-rolled part of the workpiece, which also contributes to obtaining the part with the spiral weld .
Предлагаема составна оправка позвол ет изготовл ть цилиндрические обечайки со спиральным швом различного диаметра при использовании набора подвижных колед соответствующих диаметров. При этом угол закручивани шва определ етс углом подъема пазов на корпусе, соотнощением наружных диаметров корпуса и подвижного кольца , а также выбранной степенью деформации .The proposed composite mandrel allows the manufacture of cylindrical shells with a helix seam of different diameters using a set of movable ends of corresponding diameters. In this case, the angle of twist of the seam is determined by the angle of elevation of the grooves on the body, the ratio of the outer diameters of the body and the movable ring, as well as the chosen degree of deformation.
