[0001] The present invention relates to the technical field of cable tube processing, and in particular to an MPP cable tube expansion and forming device. Background Art

[0002] During the processing of MPP cable pipes, after the cable pipes are cut and segmented, one end opening of each group of cable pipes needs to be expanded to facilitate the mutual insertion and connection of the groups of cable pipes. A specific expansion device needs to be used for processing. For example, invention patent CN110303668A discloses a high-voltage power pipe wire expander, which relates to the technical field of expanders. The expander comprises a box body, a plurality of universal wheels, a box cover, a support plate, a first servo electric cylinder, a fixed plate, a second servo electric cylinder, a first support frame, a fixed frame, a second support frame, a connecting plate and an expansion mechanism are provided at the bottom of the box body. The expansion mechanism comprises an expansion rod, an expansion sleeve, an arc block, a first mounting cavity, a spring, a second mounting cavity, an inclined surface structure, an annular groove and a fixed rod. This facilitates the protection of the device and can prevent the device from being placed in the outside world for a long time to generate dust.
