Abstract
The invention discloses a plunger self-locking metal corrugated pipe multi-corrugate water expansion once-forming machine. A forming mould is locked in a manner of pushing a pin by a locking mould cylinder. A large mould locking force is realized. In manufacturing a relatively long large-size corrugated pipe, the mould locking force can be enlarged through prolonging the length of the forming mould. No enough mould locking capability of the mould is prevented. Machining of the large corrugated pipe with relatively a large number of corrugates and a relatively high wall thickness can be finished in one step. High operation efficiency and high quality of finished product are realized. According to the plunger self-locking metal corrugated pipe multi-corrugate water expansion once-forming machine, the forming mould with an inner mould and an outer mould is adopted. In a certain range, through adjusting different moulds of different standards, the plunger self-locking metal corrugated pipe multi-corrugate water expansion once-forming machine can be adapted with manufacture of the corrugated pipes with different standards and different diameters. Specialized casting of a new forming outer mould is not required. Not only is production efficiency improved, but also the production cost is greatly reduced.
