Round Tube Expanding Machine

The Round Tube Expanding Machine is a professional hydraulic end-forming device dedicated to expanding the ends of round metal tubes.It enlarges pipe ends to form socket structures for seamless pipe-to-pipe connection,commonly used in scaffolding,greenhouse frames,guardrail components,furniture supports and various tubular assemblies.In contrast to lathe machining or additional connector welding,one-step expanding forming delivers uniform size and smooth surface,eliminating extra finishing processes and accelerating pipe assembly.

Constructed with a heavy integrally welded rigid frame,the machine effectively absorbs impact and vibration generated during continuous extrusion cycles.Custom high-hardness expanding dies ensure consistent expanded dimensions,smooth tube surfaces free of cracks,wrinkles or uneven flaring.Stable clamping fixtures tightly fasten round tubes to avoid shifting and twisting during the expansion process.Various die sets can be quickly swapped to adapt to different pipe diameters and expanding requirements for flexible order conversion.

It works with carbon steel,galvanized steel,stainless steel and aluminum round tubes covering mainstream diameters and wall thicknesses.Operators adjust expanding length,extrusion stroke and working speed through the digital control panel.Multiple groups of processing parameter recipes can be stored and instantly recalled to shorten setup time between different product specifications.The machine can operate independently or be matched with automatic feeding and cutting equipment to build a complete pipe processing production line.

For mass production workshops,automatic cyclic operation greatly increases throughput and cuts labor costs.Built-in hydraulic overload protection will automatically halt the machine when materials exceed processing limits or parameters are wrongly configured,protecting molds and equipment while reducing scrap and unplanned downtime.Reliable continuous running performance satisfies long-hour batch production demands of metal fabricators.

The intuitive human-machine interface enables on-site workers to master operation with simple training.Standard safety configurations including emergency stop and material shortage alarm ensure stable and secure daily operation.Modular die and hydraulic layout facilitates routine inspection,cleaning and replacement of wearing parts,lowering long-term maintenance expenses.

Round tubes processed by this expanding machine feature precise expanded sizes and smooth forming surfaces for direct socket assembly.Finished parts are widely adopted in scaffolding frames,greenhouse supports,storage racks,metal furniture and mechanical pipe fittings.With stable forming accuracy,strong adaptability and obvious production benefits,the Round Tube Expanding Machine is core end-forming equipment for round tubular profile manufacturers worldwide.
