Description

Technical Field

[0001] The utility model relates to the technical field of plastic-lined steel pipe production equipment, in particular to a steel-plastic pipe composite machine. Background Art

[0002] The plastic-lined steel pipe has a plastic pipe inside the steel pipe and a steel pipe structure outside. This structure has many advantages. On the one hand, it has the function of a plastic pipe and can be used to transport hot water or other liquids. Plastic has corrosion resistance and can be heat-insulated. However, since the plastic pipe is very soft, it cannot meet the requirements for high strength requirements. Therefore, adding a steel pipe to the outer end of the plastic pipe can solve these problems. In terms of production technology, we first pull the plastic pipe with a smaller diameter than the steel pipe into the steel pipe through tension, and then transport it to other processes for fixing, and then install a clamping limit and connection device at both ends of the pipe mouth, so that the plastic pipe can be prevented from running out of the steel pipe, and the limit and connection device can be used to connect the various plastic-lined steel pipes together, which is convenient for their use. In this production process, the traditional process of loading the plastic-lined steel pipes into the clamping and fixing device is to put them one by one, then fix them in position, and then install other workpieces at both ends of the plastic-lined steel pipes. This is very time-consuming and inefficient. Utility Model Content
