Description

A kind of pipe bending equipment for construction pipeline

technical field

The invention relates to a material bending equipment, in particular to a pipe bending equipment for construction pipelines.

Background technique

During construction, bending equipment is often used to bend some workpieces, such as steel bars, steel pipes, etc. Traditional bending equipment, when bending steel pipes, often deforms both ends of the steel pipe and is squashed flat, while the steel pipe is bent. The bending diameter cannot be adjusted. In the prior art, one of the pipe bending methods is to use a rotating disk to fix one end of the pipe to be bent on the workbench, and the other end to the rotating disk, and make the middle bending part of the pipe bend at the limit. On the bit column, the rotation of the rotating disk is used to realize the bending of the pipe. However, in the existing pipe bending method, the chuck or manipulator for fixing the pipe bend on the rotating disk is generally fixed, which leads to the fact that when the pipe is bent, the part of the chuck or the manipulator moves along with the pipe bending. The bending force on the clamping part of the elbow increases, which easily leads to a large bending deflection of the clamping part of the chuck or the manipulator, as shown by the dotted line in Figure 1. In this regard, there are also some chucks or manipulators that rotate when they are bent, but their rotation is generally free. This free rotation causes a great loss to the bending force of the pipe. When the pipe is bent to a certain extent, This method will increase the pulling force on the tube, while the bending force is small, which will affect the bending efficiency, and will also cause the tube to be elongated or broken.

Therefore, the present invention provides a pipe bending device for building pipelines to solve the above-mentioned problems in the background art.
