Description

Technical Field

[0001] The utility model relates to the technical field of steel ring production, in particular to a lifting and lowering expanding machine. Background Art

[0002] In order to enable the PCCP pipeline to withstand higher internal pressure, the socket and spigot of the PCCP pipeline adopt steel socket and spigot, and use rubber ring for flexible connection. For this purpose, the socket body plate and spigot body plate need to be processed into a ring shape with precisely controlled geometric dimensions. The general process is: 1. Pre-roll the socket body plate and spigot body plate; 2. Weld and polish the rolled plate; 3. Edge rolling of the socket; 4. Expand the socket and spigot again. The dimensional accuracy of the expanded socket and spigot is high, which is the key control parameter for watertightness under rated pressure after the pipe core is buried.

[0003] When the existing equipment is used to make the socket body and the plug body, the rolling machine and the edge rolling machine are all vertical, that is, the axis of the socket body and the plug body are parallel to the ground. However, due to the design of the expansion machine, the axis of the socket body and the plug body are perpendicular to the ground when working. Therefore, after the workpiece is transferred from the rolling machine and the edge rolling machine to the expansion machine, there must be a turning process, which is not only unsafe but also affects production efficiency.

[0004] At the same time, due to the vertical work, a deeper pit (about 3m deep) needs to be excavated, which is inconvenient for transfer and has high cost. Utility Model Content
