The latest all-electric BLM Elect CNC tube bender is essentially ‘two machines in one’, because it can be quickly switched into a right-hand or left-hand bend configuration.

This capability can save secondary bending operations or even the need for a second bending machine.

The Elect’s multi-stack tool mounting facility allows multi radius and variable radius bending of the same tube to take place in a single setup.

Bends with very little straight between them, even compound bends, can also be accommodated, along with tight bends that can have a radius less than the tube diameter.

The inherent precision and control of all the axes positioning guarantees consistent, accurate bends.

All critical machine setting parameters are managed by the Siemens 840D SL CNC.

This Solution-Line control system, which interfaces with BLM’s VGP3D graphical programming and simulation software, provides fully automatic and interpolated simultaneous movement of all nine machine axes.

This eliminates dead time within the tube bending cycle, ensuring that optimum output rates are reached consistently.

The VGP3D software creates the part program and displays on screen in real time the shortest and most efficient bending cycle.

Any possible collision points are highlighted and alternative strategies proposed on screen.

This collision avoidance routine eliminates any likelihood of expensive machine downtime, tool damage and material wastage.

The software simulation cycle gives the actual time it will take to bend the component on the machine.

After a tooling change the BLM Elect automatically initiates a single machine protection cycle, which runs at 20 per cent of the normal speed and power.

This ensures that should a collision be caused by inadvertent operator error it will not damage the machine or tooling.

The BLM Elect has a robust bend head and machine frame, and its compact integrated gearbox contributes to the greater clearance area around and beneath the bend head.

This enables more complex components to be completed in a single cycle.

The machine’s precise calibration cycle means that it is set right first time and a first-off part, and all subsequent parts, will be to specification.

Two models are available: the Elect-63 having a maximum tube OD capacity of 63mm (2mm wall thickness in steel); and the Elect-80 having a maximum tube OD capacity of 80mm (2mm wall thickness in steel).

Both models have an optional variable radius/boost bending facility.

CNC sheet metal bending cell’s mechanical gripper allows the bending of parts up to a DIN A4 format size and a weight of no more than 2.0kg can be automatically bent.

With the new mechanical gripper an additional module for the BendMaster automation component, now even bending parts up to a DIN A4 format size and a weight of no more than 2.0kg can be automatically bent.

The connection takes place via the pneumatic gripper coupling.

An additional sliding axis significantly reduces regripping time - by 15s for each eliminated regripping action.

The new gripper technology augments the vacuum technology in the BendMaster.

This combination makes the vending machines of the TruBend Series 5000 into universal bending cells for small and large workpieces.

Conveyor belt connection and pallet conveyor complete the logistics relating to the bending cell.

Poorly stackable components such as boxes or complex bending parts are discharged from the bending cell via the conveyor belt.

The bending process is not interrupted by the disposal of the finished parts occurring parallel to the uptime.

The pallet conveyor allows the Euro pallets to be moved in and out without interrupting the bending process.

Large series can be smoothly processed without downtime by loading new blanks parallel to the uptime and unloading finished parts.

A single control unit serves both conveyor belt and pallet conveyor.

At EuroBLECH, Trumpf demonstrated both innovations in combination with the tried-and-true TruBend 5130 and the BendMaster.

The TruBend 5130 offers a maximum press tonnage of 1,300kN on a fold length of 3230mm.

Trumpf is the only manufacturer offering the 6-axis backguage in automated operation.

The bending cells use the ACB angular position measuring system in combination with high axis speeds to achieve maximum process reliability and angle precision.

With a track up to 14 m long and the use of customized conveyor technology components, Trumpf offers maximum flexibility and productivity in the bending cell.
