Both show the domain to Trumpf bending

At first glance, is quite clear what has been the aspect in which more focused improvement of the new series TrumaBend v there is no large hydraulic cylinders fold area. This has been possible thanks to the technology of four-cylinder designed by Trumpf. But see it in more detail in this article, that also we analyze closely the automation through the Trumpf BendMaster bending.

TRUMPF BendMaster, offers an automation technology which takes into account the flexibility of folding machines. It is suitable for working with long and short production cycles.

The technology of the four cylinders of this German company offers more space to the area of folding, provides greater accuracy and higher productivity. We can identify the new series of folding by the name with which has named it. In the future, the number that accompanies the name will be used to indicate the tonnage of the machine in kN: e.g. TrumaBend V 1300.

As you know any driver car, the presence of greater numbers of cylinders means a smoother operation of the engine and increased performance. The same principle can be applied to the new series TrumaBend V: compression force acts evenly on the arm of the press and, consequently, also on the tool. This guarantees maximum precision. The size of the surface of the cylinder allows a better oil cooling and generates higher speeds with a minimum contribution of heat. In global terms, the precision of repetition has doubled to 5 µm.

"With the new series TrumaBend V, the duration of the cycle is reduced by 30 per cent", explains Jörg Ellerkmann, Director of Ventas of technologies of Plegado of Trumpf Werkzeugmaschinen GmbH + Co. KG. The reason is that the machine reaches the 220 mm/s, both the upstroke in the downward, with the same power of the engine.

In addition, the subsequent top and help of Trumpf bending system has a system of absolute measurement that makes unnecessary decision references. Therefore, is operating from the moment of putting in place machine. The role of "rolling fast" with BenGuard during the bending of plates also greatly reduces the duration of the cycle.

"The process of creating our own control system Trumpf, called TASC 6000 (English acronym of Control Advanced specialized Trumpf) meant a great advance towards the achievement of a cutting-edge interactive control", Ellerkmann said. One of the highlights of this new system of control of folding is using the same interface on screen at all times. If it is programming on the PC with the easy programming ToPs 600 system as if being directly work on the machine, the operator always uses the same interface. This interactive system Trumpf control graphical interface and the ergonomic control panel have been adapted to facilitate and accelerate programming tasks. It has a logical and self-explanatory design, contains information on the management of materials, generates the adjustment plan, and calculates the bending sequence while it performs a check of possible collisions.

The achievement of a flexible bending is further simplified with the system of measuring angles ACB. With him, the user can read the results of bending control TASC 6000 system monitor. In addition, instead of using four ACBs, as it was the case previously, the machine can be equipped with eight.

The coupling of the system of measuring angles has been improved in two ways: on the one hand, the system is connected to a contact bar located above the upper tool; Secondly, a smart connector has replaced the box of sensors. This means that the measurement system does not create a profile that hinders the bending process. All the ACB functions are integrated in the system of control TASC.

The Trumpf BendGuard system will also be connected there. It is no longer necessary to remove the self-locking security system to mount the upper tools. For the user, that means that only need to attach the connector to start work.

Numerous detail improvements, including the lower tool have been introduced. Rather than incorporate a bar of anchor, tools now are engaged through anchor piston with independent control, which also allow short pieces hold extremely well. Thus it is possible to achieve maximum productivity in the manufacture of high precision folded parts.

High productivity and precision.

A single adjustment, accurate and comfortable and safe operation are the attributes that Trumpf contributed to the folding in the early 1990s, bringing them to the category of "genuine" machine tools. With the advent of the system of measuring angles ACB and the series V high-precision, reliability and precision of repetition began to form part of the folding processes. These are the elements necessary for an accurate and flexible automation solution.

With Trumpf BendMaster, this company offers an automation technology which takes into account the flexibility of folding machines. It is suitable for working with long and short production cycles with heavy components of up to 40 kilograms, or light and complex components. The secret to achieving this is the integrated design of the machine: the folder and the BendMaster system are controlled by a single control device and are programmed jointly, with the help of the ToPs 600 system. As a result, programming robots already part of the past in the bending sector.

Is one automated folding cell not always slower than the operator of a machine? And it is not true that it is only suitable for working with large production batches? "Since the introduction of the system BendMaster, that statement is no longer certain", says Hans-Jochen Beilke, Vice Chairman of Ventas of Trumpf Werkzeugmaschinen GmbH + Co. KG. The machine BendMaster is as fast as a conventional folder and is able to maintain the pace of production every day and 24 hours a day. The BendMaster system can be used economically with less than 30 units production batches, due to its short time of programming and adjustment. The reduction of labour costs in the field of production and the absence of rejections, thanks to the use of the Trumpf ACB angle sensor, allow return on investment within two years.

Also, to schedule all folding cell using the system ToPs 600, already proven, that has an extension of automation module. The geometry of the parts must be defined once, or can be extracted from other ToPs (punching, lasers) programs. The process of bending and handling parts is then generated automatically. And best of all is that the programming is done offline, while folding cell continues to function. A simulation allows to visualize the entire process. Collision control is automatic.

The Trumpf BendMaster unit is designed to work with cycles of short duration. Your configuration of design allows extremely high speeds of placement. Plate sensor detects reliably and constant sense of stacking the plates and guarantees the elevation of the plates in the correct position. As a result, it is not necessary to have a unity of focus, or spend time in the process of focusing. Thus, the automated production can offer the same quality as the manual bending.

Operation device incorporates several suction cups of series. The reliability of the process is ensured by the presence of a system of integrated sensors. The standard suction cups are contained in the programming software, but can be easily imported other special suction cups to the library. The placement of the suction cups on the grill is automatic and is based on the position of the holes and gaps in the work piece.

BendMaster unit is installed to the folder, in a lane of fixing of land that spans the entire area of work of the TrumaBend folder. Load greater than 180 ° can work with palettes and have free access to the lift truck. The rail fastening of floor can be extended to length desired economically, increasing the area of deposit of the finished pieces and avoiding the need of having to make additional investments in transport systems.

"Those who work with BendMaster have no why sacrifice flexibility", explains Hans - Jochen Beilke. If necessary, the cell by bending can be run manually at any time. As BendMaster has a front arm of great length, the operator of the machine has enough room in front of the machine when the robot is in parked position. Flat design of the ground setting Lane has a minimum profile of collision.
