Description

Technical Field

[0001] The invention relates to the technical field of oil pipe processing, and in particular to a bending device for producing engine oil pipes which is convenient for material cutting. Background Art

[0002] The oil pipe is usually formed by bending a metal pipe, and the oil pipe usually has multiple bending points. The current common CNC bending machine usually includes an oil pipe clamping device, an oil pipe delivery device and an oil pipe bending module. When in use, the oil pipe clamping device and the oil pipe delivery device clamp the end of the oil pipe and drive the oil pipe to move and rotate, so that the bending point of the oil pipe moves to the oil pipe bending module for bending.

[0003] For example, Chinese patent CN115740132A discloses a metal pipe bending machine that is easy to clamp.
