Automatic Double Expansion Machine Hornung DW825

Automatic Double Expansion Machine Hornung DW825


Hornung DW825 Automatic Double Expansion Machine from Andreas Hornung Maschinenbau is a high-performance, automated hydraulic machine designed for the simultaneous expansion of both ends of thin-walled metal pipes and fittings. A key feature is its angular offset technology for secondary expansion, which ensures perfect forming quality for sockets and stop beads. The machine is ideally suited for the serial production of fittings where high speed and consistent quality are paramount.

Features and Advantages

Feature Advantage
Double Expansion Simultaneous processing of both pipe ends significantly accelerates production, allowing for the creation of a socket and a stop bead in a single cycle.
Angular Offset Expansion Exceptional forming quality — after the first expansion, the heads shift, rotate by 30°, and expand again. This ensures a highly accurate and uniform shape for the socket and bead.
Rapid Cycle Time High productivity — processing time (excluding handling) is only 8 seconds, with a full cycle including transport taking 12 seconds.
Touchscreen Programming All inputs and settings are handled via a Siemens touch panel connected to a Siemens S7 PLC, guaranteeing precision and repeatability.
Efficient Tool Change Tools are held together by O-rings (as in the W6 series), simplifying and speeding up replacement without the need for separate fasteners.

Configurations and Automation

The machine is available in two primary configurations:

  • Base Machine:

    • Manual feeding and removal of pipes by the operator.

    • The processing cycle occurs automatically.

  • Machine with Discharge Table and Ejector:

    • Pipes are manually inserted and automatically expanded.

    • A specialized ejector automatically lifts the processed pipe onto a discharge table.

    • The control system automatically stops operation when the table (standard length 2 m, other lengths available) is full.
