Fully electric bending machine, with right and left bending in process and 3D graphic visual programming (VGP3D)

Some features of E-TURN fully electric machine:

  • No mechanical adjustment is needed
  • In-process right and left bending, with fixed and variable radius
  • Reduced time for programming and change-over
  • Enhanced controllability and repeatability
  • Increased productivity (by even 20% compared to hydro-electric machines)
  • Widest flexibility, thanks to the reduced dimension of the bending head and of the free bending and variable radius positioning
  • Increased feasibility of more complex structures
  • Tool holders designed for the fully interchangeability with existing BLM machines
  • Integrated machine load and load


The machine is programmed by the programming and 3D simulation software BLM VGP3D which allows:

  • component feasibility can be checked without physically testing on the machine or making prototype tooling
  • pre-production calculation of the real cycle time is known, so production costs and component pricing can be more precise
  • by simply inputting the components bend coordinates, the complete bending program is graphically simulated


Machine available in three versions:
ET32 - maximum tube O.D. capacity from 6 to 32*2mm
ET35 - maximum tube O.D. capacity from 6 to 35*2mm
ET40 - maximum tube O.D. capacity from 6 to 40*2mm
ET52 - maximum tube O.D. capacity from 6 to 52*2mm

Loader / unloader

SOLUTIONS

Thanks to the wide range of feeders and loaders, customers can choose the best suitable solution for their needs.

Following some key features of our handling systems:

  • loading of tubes with round and non-round section
  • loaders can be set up for installation of both machine sides (right/left)
  • existing tools are fully interchangeable, no new tool is required
  • the weld seam detection can be integrated directly on the loader
  • load and unload operations can be managed directly by the programming software VGP3D

Increase up to 200% of the productivity

Thanks to the perfect axis interpolation we could exploit at their best the simultaneity logics generated by our programming software VGP3D, with a cycle time reduction from 50% to 200% compared to machines without interpolation.

Reduced maintenance costs

The proposed solutions make the wiring on the machine easier. This means easy maintenance and reduced causes of breakdowns.

The limit switches on the cylinders, the mechanical adjustments and the connection cables often cause unexpected and unwanted machine breakdowns.

The removal of all hydraulic devices such as fittings, tubes, cylinders and valves allow to reduce the machine components usually subject to maintenance, wear and breakage. The full-digital connections of the motors give the possibility to obtain information about the diagnostic of each single component and an important reduction of the reaction and maintenance time.

This means higher reliability of the components and therefore of the machine.

Up to 80% lower power consumption

WHY AN E-TURN

The electrical axes for the movement of the main components of the machine allow a drastic reduction of the consumption compared with all bending machines of the same size but older and therefore electric-hydraulically driven.

When the motor is still, the speed is null and therefore also the absorbed power. This is not the case of an electric-hydraulic machine. As a matter of fact, when the machine is not working, the hydraulic circuit requires the continuous functioning of the pump in order to keep steady the machine pressure and therefore it consumes, also if it not working, a lot of energy.

It’s Environment-friendly

WHY AN E-TURN

It's Environment-friendly (reduced noise level, no mineral oils, extremely reduced power consumptions).

The use of electric axes and the absence of the hydraulic cabinet grant a big reduction of noise and vibrations. Moreover, each single device is moved by a acceleration and deceleration ramp preventing crashes between the tools.

The noise level is lower than 70 dB (A). As confirmed by many studies. The lower noise reduces the fatigue of the operator and improves the working environment.

B-TOOLS - 1° piece is right

Each electric axis is driven by the control and its position/adjustment is saved with the part program. When tool is changed, it is no longer necessary to perform annoying adjustments of the machine because these are made using the electric movement of the axes.

The reduced tool set up time is a big advantage in order to produce small batches and to reduce scraps when the machine is adjusted after changeover.

The saved material for the tool set up brings an economic benefit of 7.000,00 EUR/year.

Moreover all set-up parameters are saved with the program therefore the set-up times are very short and, most of all, thanks to the position repeatability a particular knowledge of machine set-up is not required.

Feasibility of complex shapes

WHY AN E-TURN

Electric drivers allow the production of very tight radii and of complex shapes with guaranteed repeatability. In particular:

  • medium bending radius 1D.
  • ovalisation < 1%;
  • thickness reduction < 20%;
  • no clamping marks

Countless advantages thanks to the integration and control of all possible tube processes (cutting - bending - end-forming - measure).

PROCESSES

More in particular, the combination of laser and bending processes in a  production cell allows:

  • high repeatability and quality thanks to the mask control on 100% of the products;
  • simplified production process. Further piece machining on additional equipment is not required;
  • guarantee of flexibility for further different uses of the system.


The process includes more machining in one cycle:

  • load
  • laser cutting
  • unload
  • precise piece orientation to guarantee the correct positioning after the bending
  • bending
  • unload

This process is particularly suitable for applications such as furniture, automotive and motorcycle.

PROCESSES

This production process is used when the laser process has to be made on bent tubes (trimming, punching, grooving on bending, etc.).  More in particular, it is used for automobile chassis exhaust pipe production in extremely competitive
times and quality.

More processes in a single cycle: loading -pipe singling out -inspection - welding - bending - laser cutting -unloading, for:

  • high repeatability and quality thanks to the mask control on 100% of the products;
  • high productivity thanks to cycle time optimization of the single cutting and bending processes;
  • constant production quality on three working shifts, even in lights-out operation.
