Description

Technical Field

[0001] This utility model relates to the field of metal bending technology, and in particular to a metal bending device. Background Technology

[0002] The core function of a metal bending device is to apply a controllable force to cause plastic deformation of metal sheets or profiles at a specific location (bending line) to form the required bending angle.

[0003] Currently, when bending metal pipes, the metal pipes are placed on a bending machine for bending. Because the bending machine is hollow inside, it applies an outer wall to the metal pipe, causing the metal pipe to deform. However, there are still some shortcomings: during the bending process, only pipes of the same diameter can be bent in one direction. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned shortcomings by providing a metal bending device that enables bending of pipes of different diameters in multiple directions.

The first telescopic component is provided with a drive component, the drive component is provided with a rotating column, and the rotating column is provided with an annular plate for accommodating clamping of metal pipe fittings of different diameters.

[0010] Furthermore, the bending mechanism includes a crossbar mounted on the rotating column and a second telescopic assembly mounted on the crossbar.
