Description

TECHNICAL FIELD

[0001] The utility model belongs to the corrugated pipe production technical field, specifically, and particularly relates to a forming machine for metal corrugated pipe production. BACKGROUND

[0002] Metal corrugated pipe is a wave-shaped pipe material with regular appearance, and commonly used metal corrugated pipes are carbon steel and stainless steel, and there are also steel lined plastic and aluminum ones. It is mainly used for connecting pipes and pipes, or connecting pipes and equipment in situations where it is difficult to install fixed elbows, or for small bending radius non-concentric axial transmission, or irregular turning, expansion, or absorbing thermal deformation of pipes, etc.

[0003] A metal corrugated pipe rapid forming machine is disclosed in Chinese patent CN221869905U, which relates to the field of corrugated pipe manufacturing. The metal corrugated pipe rapid forming machine comprises a high-pressure liquid delivery mechanism, a hydraulic cylinder one, a lower mold and an upper mold. Two mounting columns are fixedly installed on the top rear side of the high-pressure liquid delivery mechanism. The hydraulic cylinder one is fixedly installed at the top end of the two mounting columns. A vertical plate is fixedly installed between the hydraulic cylinder one and the high-pressure liquid delivery mechanism. The upper mold is slidably installed on the front surface of the vertical plate.

[0004] In the current corrugated pipe production, horizontal hydraulic forming machines are mainly used. Since the pipe blank is placed horizontally inside the mold cavity, there is usually a lot of liquid left in the pipe after the corrugated pipe is formed. When the worker or the robot arm takes out the corrugated pipe from the horizontal hydraulic forming machine, the liquid may splash onto the mold or the machine inside and even the ground around the machine, causing waste of liquid resources and making it difficult to recycle and reuse. In the above document, the corrugated pipe is placed vertically, and the liquid in the pipe will flow downward under the action of gravity, so as to avoid waste of liquid resources. However, the corrugated pipe is deformed from the inside out during the forming process, which makes it difficult to remove the corrugated pipe from the mold.

[0005] At present, there is no effective solution to the problems in the related art. UTILITY MODEL CONTENTS
