Shaping Of Tube Ends By Bending Or Straightening

Abstract
FIELD: manufacturing corrugated articles. SUBSTANCE: mandrel is made up as a set of pivotally interconnected members to vary its shape. The pivots are at the points where an article should change its shape. In laying a blank the mandrel is flat. Due to pressurization of pressure-tight hoses arranged along the Z-shaped lines of projections, the mandrel ceases to be flat. The final shape of the mandrel is defined by its squeezing in the horizontal plane. EFFECT: expanded functional capabilities. 3 dwg
