The invention discloses a pipe multi-section heating device used before PVC-O pipe fitting manufacturing. The pipe multi-section heating device comprises an inner-layer heating mechanism, an outer-layer heating mechanism and a traction mechanism, wherein the inner-layer heating mechanism is arranged in a pipe fitting and used for heating the interior of the pipe fitting; the outer-layer heating mechanism is detachably connected to the exterior of the pipe fitting and used for heating the exterior of the pipe fitting; and the traction mechanism is used for driving the pipe fitting to translate along the inner-layer heating mechanism and the outer-layer heating mechanism. The device is simple and reliable in structure and uniform in heating, and sectional temperature control adjustment is formed through the multi-section heating structure composed of an inner layer and an outer layer in cooperation with a control mechanism, so that heating operation is conducted according to the heating temperature requirements of different stages of a pipe fitting, the temperature control effect is good, and the heating effect is effectively improved.
Description
technical field [0001] The invention relates to the technical field of material preparation, in particular to a multi-stage heating device for pipes before the preparation of PVC-O pipe fittings. Background technique [0002] PVC-O pipe rearranges the molecules of the material through bidirectional stretching at the glass transition temperature of the PVC material, so that the material (pipe wall) forms a network structure, which can withstand micro cracks originating from the material body or scratches on the surface of the pipe wall. The brittle failure of the cracks significantly improves the strength, toughness and crack resistance of the pipe. Biaxially oriented polyvinyl chloride (PVC-O) pipe is a pipe manufactured through a special orientation process. This process is to stretch the PVC-U pipe produced by the extrusion method axially and radially. The PVC long-chain molecules in the pipe are regularly arranged in the biaxial direction, and a new type of PVC pipe with...
