METAL-PLASTIC COMPOSITE PIPE COMPOUNDING DEVICE AND COMPOUNDING PROCESS

WIPO Patent Application WO/2022/121676

A1

The present invention provides a metal-plastic composite pipe compounding device and a compounding process, the compounding device comprising a material conveying apparatus, a workbench, and a support apparatus, a clamping assembly and a heating and cooling apparatus which are mounted on the workbench. The clamping assembly may move on the workbench; the material conveying apparatus moves a pipe to be machined into or out of the support apparatus; the support apparatus supports the pipe to be machined and may drive same to ascend or descend; the clamping assembly clamps and seals two ends of a plastic pipe of the pipe to be machined; and the clamping assembly drives the pipe to be machined to pass through the heating and cooling apparatus. In the present invention, a feeding process, a clamping process, heating and cooling processes and a discharging process may be completed in sequence by means of the compounding device. The device has a compact structure, occupies a small area, is suitable for batch composite production lines, can be suitable for compounding pipes to be machined having relatively large diameters, has high compounding and machining efficiency, and has a high compounding performance.
