OverviewConceptsTechnology

Lighter, stronger: Along with the increasing requirements for chassis components in vehicles, the requirements for intelligent production processes in the automotive industry have been ever increasing over the last years. The solution is hot forming: A temperature and time related forming process where heated rough blanks in soft condition are formed to high-strength, lightweight components. By means of your Graebener® special press, the heated rough blanks are formed using a cooled forming tool and simultaneously cooled down in a controlled way.

Graebener® is your partner for customized special solutions. From the individual Graebener® hot forming press up to the entire line control we support and accompany you in cooperation with experienced partners on the path to your optimum solution. Based on our process know-how we, together with our partners, also offer intelligent solutions for the central control of your production line. Make use of our network.

Graebener®, as forming specialist with worldwide success, has been specializing on customized press solutions in the hot forming sector for many years. Each machine is matched and tailored for the respective type of application. A 4-column press design serves as mechanical base structure:

4-Column Press

The 4-column press is perfectly suitable for the integration into a hot forming line. Upper and lower traverse are connected by means of pre-tensioned tie rods. This design offers comprehensive advantages: on the one hand the press frame is very solid and offers an optimum deflection compensation. On the other hand, this design allows easy access to the tool area for the operator from all four sides. Therefore, the components can also be processed automatically without any problems.

4-column presses are used for a wide range of application. They are standardized for closing forces of 630, 800, 1,000, 1,200, 1,500, 1,700, 2,000, 2,500, 3,500 and 5,000 tons.

From mechanics to hydraulics, control and feedback control technology. A Graebener® machine always stands for an optimum technical solution

An optimum forming process is also depending on a perfect interaction of operator and machine. For this purpose, the visualization system PressPro® has been developed. With the aid of PressPro®, the operator can develop, optimize and execute the forming process independently. The open and flexible system allows freely definable process steps for prototyping as well as for series production. Pre-defined sequences can be assigned to each tool, saved in the corresponding tool data base and accessed from there as well. Main advantage: The time between the tool set-up and the production of the first "good" part can be reduced significantly.

MLC

For an optimum control of the highly complex process sequence we have been working successfully with our partner Bosch Rexroth for many years. Based on the Motion Logic System Indra-Motion MLC, Rexroth has developed a completely new control and feedback control system which has been tested exclusively in our Prototyping Center and continuously refined later on from both partners. The entire control system for hydraulic, electric and hybrid drives builds on a compact controller-based hardware. Here the PLC merges with the motion controller to a new system.
