Description

Technical Field

[0002] Pipe bending machines are industrial processing equipment specifically designed to bend metal pipes into specific angles, arcs, or complex shapes. They are widely used in the automotive, aerospace, furniture, and piping engineering industries. Their core working principle involves fixing the pipe with a fixing mechanism, and then a drive system using a die to apply controllable pressure to the pipe, causing it to undergo plastic deformation along a preset path. Some models are equipped with a feeding mechanism to achieve continuous bending or multi-station processing. Based on the bending method, they can be classified into CNC pipe bending machines, hydraulic pipe bending machines, and manual or semi-automatic pipe bending machines, meeting different processing needs for precision, pipe specifications, and production efficiency.

[0003] Chinese patent CN223476013U discloses a hydraulic pipe bending machine, relating to the field of pipe bending tool technology. The hydraulic pipe bending machine includes a base, a hydraulic device, two first rollers, and two second rollers. The base forms a working space. The two first rollers are spaced apart within the working space, with both ends of each first roller connected to opposite side walls of the base.
