DEVICE AND METHOD FOR LOOPER BENDING

摘要

A loop bending apparatus is provided to automatically bending a pipe with an ellipse shape by supplying a material to a loop bending jig and continuously bending the material. A loop bending apparatus(60) comprises a loop bending jig(68) in which the deformation object is flowed in and which bending is transformed; a driving force transmission part which delivers the driving force in order to move the loop bending jig up and down; a location servo(40) supports a deformation object(50) and moves in order to flow in and out to the loop bending jig. The driving force transmission part in the case(65) of the loop bending apparatus, includes a spline shaft(32) increasing the loop bending jig and a spline boss(36) in which the spline shaft is inserted and which is fixed.
