Universal bending device for bending pipes or section bars to constant curvature and variable curvature

摘要

Apparatus for bending pipes or section bars according to the invention are for work elements in which at least two powered spindle projections are formed and for reaction members designed to interlock with a bender roller or matrix according to a constant or variable radius in bending operation. Supporting means; At least one of the spindle protrusions is powered to rotate in one direction, and the at least one spindle protrusion is driven to be idle or to rotate in the opposite direction; The spindle protrusions are accessible for mounting on or disengaging from a spindle designed to support each of the matrix or bender rollers defining a working area on the workbench for bending along a constant or variable radius; The support means can be firmly positioned on the linear guide means in the work area in the direction of approaching the reaction member to the work area and in the direction of removing the reaction member from the work area.
