Cold-bending device and method for pipeline

Abstract

The invention discloses a cold-bending device for a pipeline. The cold-bending device for the pipeline comprises a first workbench, a first bending element, a first limit element, a first rotary element, and a second bending element, wherein the first bending element is arranged on the first workbench, and the sidewall of the first bending element is a cylindrical sidewall; the first limit elementis arranged on the first workbench, and spaced with a certain distance away from the first bending element; the first rotary element is located at one side away from the first workbench, of the firstbending element, and rotationally connected with the position of the central axis of the first bending element, a rotary plane is parallel to the bench surface of the first workbench, and the two ends of the first rotary element stretch out of the sidewall of the first bending element separately; and the second bending element is connected with one end of the first rotary element, and located between the first bending element and the first workbench. According to the cold-bending device for the pipeline, in a use process, the pipeline is bent in the manner of cold-bending in a whole bending process, the pipeline can be protected from being damaged, the quality of pipe bending is ensured, and a bent pipe with a corresponding angle can be produced as needed.

Description

technical field [0001] The invention relates to a pipe bending device, in particular to a pipe cold bending device. Background technique [0002] At present, there are many small-diameter pipes on the construction site, especially furnace pipes, handrails, industrial pipes and heat tracing pipes. However, in the installation process, the finished elbows are generally not provided, and all the elbows need to be made on site. The workload of this part is relatively large, and there are many damages and deformations during the bending process. [0003] At present, the bending of small-diameter pipes on the pipeline site is basically carried out by hot bending, but in the heat pipe process, not only the angle is limited, but also it is easy to be deformed and damaged, which affects the processing quality of the bent pipe. Contents of the invention [0004] The object of the present invention is to overcome the above-mentioned problems in the prior art and provide a pipe bendi...
