Sommer Maschinenbau GmbH S80

Mandrel Bending Machine S8004
-----
For the production of dimensionally accurate tube geometries with bending radii up to 1.5xD
→ Maximum bending capacity tube 76 x 4 mm (400 N/mm²)
→ Maximum bending capacity tube 60 x 60 x 3 mm (400 N/mm²)
→ Maximum bending capacity tube 76 x 2.9 mm (stainless steel)
→ Total connected load 7 kW
→ Maximum tube loading length 4.5 m

Robust and durable steel construction with a rigid, torsion-resistant connection – no twist-prone components such as a split construction between bending head and mandrel carrier. Maintenance-free electromechanical drive for the bending axis. The touchscreen control panel allows for easy and intuitive programming and operation of the machine. After loading, the tube is clamped in the travelling chuck, ensuring precise tube positioning for dimensionally accurate geometries. Standard equipment also includes a check of tube geometry prior to bending: if the bending process is initiated from the wrong position, the machine will not start, preventing operator errors. Optional additional features provide more comfort, increase output, and enhance overall system efficiency.

Data exchange with the optional TBS-3D tube calculation software (PC version) is possible via USB stick or by FTP access from the computer to the machine control. USB or LAN ports (RJ45) are standard. Existing tube geometries can be easily and quickly converted, e.g., via the STEP format.

→ ETH 10/100, X2X Link, USB
→ Foot pedal operation
→ Data transfer via (W)LAN or USB
→ Material database
Unique graphical programming: simple geometries can be calculated directly on the machine. Once length and angle are entered, the system calculates the feed values and bending angles automatically.

Hydraulics:
→ Hydraulic power 3 kW
→ Hydraulic tube clamping with adjustable clamping pressure
→ Programmable pre-retract mandrel

Options (can be ordered as extras):
→ Variable bending speed via frequency inverter or servomotors
→ Automatic tool retraction (manual or controlled)
→ Pneumatic chuck
→ Automatic mandrel lubrication
→ Pneumatic stop system (length + rotation)
→ Mobile version (on wheels)
→ Radius extension
