Abstract
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multi-stage, multi-stage bending apparatus for straight bars capable of bending a straight bar very quickly and quickly for use in making products such as hinge torsion bars for automobiles.
In the multi-stage multi-dimensional bending apparatus of the straight bar as described above, the linear bar is formed by bending the linear bar to the desired shape by the linear bar bending processing unit, and then using the straight bar clamping member to rotate the straight bar to the desired bending angle, and then again the straight bar. The bending bar allows the straight bar to be continuously formed into a desired shape, thereby eliminating the need to remove the primary bent straight bar from the straight bar bend, and to perform the bending after the first bending. Since the operator does not have to manually rotate the straight bar at the bending angle, the straight bar can be bent in a multi-dimensional manner in the desired direction and the desired shape continuously so that the bending molding work efficiency can be greatly improved and the bending work time can be greatly shortened. Can not only improve productivity There are effective.
