Description

Technical Field

[0001] This utility model belongs to the field of metal pipe processing technology, and specifically relates to a metal pipe bending device. Background Technology

[0002] The principle of metal pipe bending is mainly based on the plasticity and deformation capacity of metal materials. During the bending process, the metal pipe undergoes plastic deformation under the action of external force, thereby achieving the desired bending shape. Pipe bending machine: The pipe bending machine is the main equipment for bending metal pipes. It typically consists of a fixed clamping die and a movable clamping die. The pipe is placed between the two, and the movable clamping die moves and merges with the fixed clamping die, thus clamping the pipe. Then, the movable and fixed clamping dies rotate together to achieve the bending operation of the pipe. Other auxiliary equipment includes: such as a pipe upsetting machine (used to upset the pipe to maintain stability during bending) and a cutting machine.

[0003] When bending a metal tube, if the ends are not restrained, the tube will be in a relatively free state during the bending process. Because metal has elasticity and plasticity, it will deform when subjected to external force. However, when the external force is removed, the metal tube will try to return to its original state. This phenomenon is called "stress rebound". Stress rebound will cause the shape of the metal tube after bending to be inconsistent with expectations, especially the bending angle will deviate. Because the metal tube is subjected to local stress during bending, this uneven stress state will aggravate the effect of stress rebound, making it difficult to guarantee the consistency of the bending angle.
