A pipe bending apparatus

Abstract

The utility model relates to the field of pipe bending equipment, concretely is a kind of pipeline pipe bending equipment, including frame body, pipe bending main body and preheating unit.Pipe bending main body is located at frame body top;Preheating unit is located on pipe bending main body, for heating the pipeline on pipe bending main body.Use, first need to fix pipeline, then activate preheating unit to pipeline preheating, then start pipe bending main body to realize hot-pressing effect.Such design can effectively soften pipeline, reduce the risk of breakage of pipeline in the bending process, improve the success rate and quality of pipe bending.Meanwhile, the cooperation between each component is accurate, for example, the push rod of hydraulic press and the electric heating wire of preheating unit are ingeniously combined, so that heating and bending action are performed consecutively, improving the efficiency of the whole pipe bending operation.
