Condition: like new (used), Year of construction: 2023, Mandrel Bending Machine S4501 ---- For the production of pipe geometries with bending radii from 1.5xD → Maximum bending capacity: pipe 42.4 x 3.25 mm (steel max. Re 240 N/mm²) → Maximum bending capacity: pipe 30 x 30 x 3 mm → Maximum bending capacity: pipe 42.4 x 2 mm (stainless steel max. Rp0.2 260 N/mm²) → Total connected load 3 kW → Pipe insertion length approx. 1.5 m Robust and durable steel construction. Maintenance-free servo drive for the bending, feed, and twisting axes. The control system's touchscreen display enables simple and intuitive programming and operation of the system. After the pipe is inserted, it is secured in the carriage by the chuck. This enables precise positioning of the pipe and thus the creation of dimensionally accurate geometries. The standard also includes a check of the pipe geometry before the bending process: If the bending process is started in the wrong position, the machine will not issue a release. This eliminates the risk of incorrect operation. Optional additional features provide greater convenience and increase output, thus increasing the efficiency of the system. Data exchange from the optional TBS-3D pipe calculation program (PC version) takes place via USB stick or network. Existing pipe geometries can be imported using the software. Standard equipment: → 1.5 kW servo drive for the bending axis → Adjustable speed Nledpfxetr U Hle Af Ejh → Left-hand bending direction → Bending angle resolution 0.1° → Max. bending radius 120 mm → Bending shaft diameter 50 mm → Feed servo drive → Rotation servo drive → Three-jaw chuck for locking the tube in the carriage → Pneumatic tool retraction Hydraulics: → Hydraulic tube clamping with adjustable clamping pressure → Programmable early mandrel retraction PLC control: → 10" color touchscreen → ETH 10/100, X2X Link, 2xUSB → Foot switch operation → Data transfer via LAN or USB network → Material database Unique graphical programming: Simple geometries can be calculated directly on the machine.
