Stanje: zelo dobro (rabljeno), Funkcionalnost: popolnoma funkcionalen, Leto izdelave: 1989, Premer cevi (maks.): 42 mm, Dolžina cevi (maks.): 3.000 mm, radij upogibanja (maks.): 180 mm, debelina stene: 3 mm,

Stanje: rabljeno, Leto izdelave: 2017, Premer cevi (maks.): 80 mm, dolžina vpenjala: 4.500 mm, Mandrel Bending Machine S8004 ----- For the production of dimensionally accurate tube geometries with bending radii of 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 → Tube loading length: 4.5 m Robust and durable steel construction in a rigid, force-locking design – no twist-prone construction resulting from, for example, split design of bending head and mandrel carrier. Maintenance-free electromechanical drive for the bending axis. The control’s touch display enables easy and intuitive programming and operation. After inserting the tube, it is fixed by the chuck in the carriage, ensuring precise tube positioning and thus the production of dimensionally accurate geometries. The standard equipment also includes geometry checking prior to the bending process: If bending begins in the wrong position, the machine does not grant release, thus ruling out operating errors. Optional additional features provide more convenience and increase throughput as well as the system’s efficiency. Data exchange from the optional TBS-3D tube calculation software (PC version) is possible via USB stick or FTP access from the computer to the machine controller. USB and LAN (RJ45) connections are included as standard. Existing tube geometries can be easily and quickly converted, e.g., via the STEP format. Standard equipment: → Electromechanical drive for bending axis, 4 kW → Rotational speed 2.9 rpm (=17°/sec.) → Bending direction: left → Bending angle resolution: 0.1° → Max. bending radius: 200 mm → Bending shaft diameter: 50 mm Djdpfx Acottah Rj Nsch → Electronic length measurement ±0.1 mm → Electronic rotation angle measurement ±0.1° → Manual stop system (longitudinal stops) → Manual indexing system (15° in rotation) → Three-jaw chuck for securing tube in the carriage → External control panel PLC control: → 10.1" touchscreen → ETH 10/100, X2X Link, USB → Foot switch operation → Data transmission via network (W)LAN or USB → Material database Unique graphic programming: simple geometries can be calculated directly on the machine. After entering length and angles, the control computes the feed and bending angles directly. Hydraulics: → Hydraulic power 3 kW → Hydraulic tube clamping with adjustable clamping pressure → Programmable pre-emptive mandrel retraction Options (available as additional equipment): → Variable bending speed via frequency inverter or servo motors → Automatic tool retraction (manual or controlled) → Pneumatic chuck → Automatic mandrel lubrication → Pneumatic stop system (length + rotation) → Mobile version (on rollers) → Radius extension Images show new machine
