Mandrel tube bending machine

Sommer Maschinenbau GmbH S80

Mandrel bending machine S8004
-----
For the production of dimensionally accurate pipe geometries with bending radii of up to 1.5XD
→ maximum bending performance pipe 76 x 4 mm (400 N/mm²)
→ maximum bending performance pipe 60 x 60 x 3 mm (400 N/mm²)
→ maximum bending performance pipe 76 x 2.9 mm (stainless steel)
→ total connected load 7 kW
→ pipe length 4.5 mtr

Robust and durable steel construction in a force-locking connection - no construction susceptible to torsion due to, for example, the split construction of the bending head and mandrel carrier. Maintenance-free electromechanical drive of the bending axis. The touch display of the control enables simple and intuitive programming and use of the system. After the pipe has been pushed on, it is fixed in the carriage by the chuck. This enables the pipe to be positioned precisely and thus the creation of dimensionally accurate geometries. The standard also includes checking the pipe geometry before the bending process: If the bending process is started in the wrong position, the machine does not give permission for this. This prevents incorrect operation. Optional additional features provide more convenience and increase the output and thus the efficiency of the system.

Data is exchanged from the optional pipe calculation program TBS-3D (PC version) via USB stick or via FTP access from the computer to the machine control system. USB or LAN connectors (RJ45) are available as standard. Existing pipe geometries can be converted quickly and easily, for example, using the STEP format.
