Description

Technical Field

[0001] The utility model relates to the technical field of pipe threading machines, in particular to a single-tube pipe threading machine. Background Art

[0002] Heating pipelines are often needed in the daily heating construction process. Heating pipelines are an important part of heating projects. Heating pipelines are used to transport thermal media to user terminals. They must have strong corrosion resistance, leakage resistance, heat resistance and other properties to meet the needs of production and life.

[0003] During the production and processing of heating pipelines, a pipe insulation layer needs to be put on the outer ring of the pipe body through a pipe threading machine. The pipe insulation layer is also called the thermal pipe insulation layer, which refers to the layer structure wrapped around the outer periphery of the pipe that can play a role of heat preservation and heat insulation. The pipe insulation layer usually consists of three layers: insulation layer, protective layer, and waterproof layer. When the existing pipe threading machine puts the insulation layer on the pipe body, it usually uses a conveying device to carry the pipe body into the insulation layer. When the pipe body is inserted into the insulation layer, the operator needs to surround more brackets in a circle and place them on the pipe body. When the insulation layer is worn to the position of the bracket, When the pipe body is inserted into the insulation layer, the bracket is supported to expand the insulation layer, thereby reducing the friction between the insulation layer and the pipe body, thereby making it easier for the pipe body to penetrate into the insulation layer. However, this method of expanding the insulation layer is time-consuming and labor-intensive. Multiple brackets are connected by wires. Since the insulation layer is tightly attached to the pipe body, it is difficult for the bracket to be inserted between the insulation layer and the pipe body. When the pipe body continues to penetrate into the insulation layer, the bracket is easily supported by the insulation layer and moves on the pipe body, thereby easily reducing the support effect of the bracket on the insulation layer and reducing the efficiency of the pipe body passing through the pipe.
