Description

Corrugated pipe forming device Technical Field The utility model relates to the technical field of corrugated pipe forming, in particular to a corrugated pipe forming device. Background The corrugated pipe is a tubular elastic sensitive element formed by connecting foldable corrugated sheets along the folding and stretching directions, and the corrugated pipe can be divided into a metal corrugated pipe and a nonmetal corrugated pipe according to the constituent materials. The metal corrugated pipe is formed by water expansion, pressure wave, hydraulic forming and the like. When the hydraulic forming equipment is used for extruding the metal pipe in the die by using the hydraulic rod, the metal pipe at the position of the hydraulic rod is positioned in the die, but the end part of the metal pipe outside the die is also lack of enough internal support, only the push head at the position of the hydraulic rod extends into the metal pipe partially, and the metal pipe inside the rest of non-corrugated forming sections is lack of enough support, so that the metal pipe can be bent and deformed inwards during extrusion, and the forming failure is caused.
