Highly productive transfer presses for sheet metal forming
A reliable production process for complex components requires several forming steps. However, using transfer presses is an optimal solution to guarantee an efficient forming process. A consistent and integrated overall automation concept is the basis for highly efficient production.
For an optimal manufacturing process, all process steps from material supply, through to component handling and discharge of the finished formed product must be perfectly coordinated hand in hand. With our competent project team, not only do we provide you with the perfect transfer automation solution, we also offer a complete concept and support you in choosing the right press partner. The level of automation of the entire forming line depends entirely on your requirements, and the automation concept is determined by your forming process.
The optimum transfer press for your needsTransfer presses are automated multi-stage presses characterized by a high degree of automation. Components for which the forming process is too complex to be reproduced in a single process stage are produced on multi-stage presses. A transfer system for part transport is used to transport the components automatically through the multi-stage tool or the transfer tool.
Eccentric or toggle presses are particularly suitable for use as transfer presses. Hydraulic forming presses can also be used for large deep-drawing processes or, if flexibility is required, servo presses. Depending on the forming process, the parts are transported in 2D mode (close feed open return) or in 3D mode (close lift feed forward feed lower open return). Parts can also be transported on one side with clamping grippers or on two sides with grippers positioned underneath and/or also with clamping grippers.
We are happy to support you in cooperation with our project team during the implementation of your new production concept. Feel free to contact us!
Material feed via coil or plate? Why not both?As a rule, a transfer press is fed either via a strip feeder or via a blank loader or parts loader. At DREHER Automation, we are able to offer you innovative solutions for handling coils as well as blanks.
Thanks to the latest developments in forming technology and the automotive industry, however, the demand for flexibility in your production processes is also steadily increasing. So why not use a combination of strip feeder and blank loader for feeding? In this way, you can process strip materials and blanks on a single transfer press. The integration of a blank buffer or a part buffer to equalize changeover times can also be implemented. Or you can use your strip feeder in combination with a blank stacker and blank loader as a blanking need when the transfer press is not needed.
After the forming process, the finished components are discharged from the transfer press via a finished parts conveyor, preferably with a removal feeder, or using another end-of-line solution.
Redefine your production process, develop innovative automation concepts with us and increase the productivity of your pressing operation.
Increased efficiency with an integrated control conceptOur control concept developed together with Siemens will complete your comprehensive system concept across all system components (conveyor system, multi-stage tool, and transfer press). Our S7 controller with Safety Integrated (Performance Level d) is not only compatible with any press controller. We can also take care of press control, for example as part of a press retrofit of an existing press.
Furthermore, at DREHER Automation we appreciate the productivity-enhancing advantages of user-friendly and self-explanatory operation and visualization. For this reason, not only does our system visualization take place on spacious touch panels at a central location via WinnCC (TIA portal) - we will also gladly develop a unique visualization concept for the entire forming system for you. Synoptics for automatic operation and sequence synoptics for tool changes are mandatory for all our customers.
The automation level of our systems is always variable. Have you already thought about changing to a fully automatic tool? We work together with you and the press manufacturer to develop an appropriate concept and implement these processes across all components (press automation and forming press).
Our systems are renowned in the industry for their longevity. This is also guaranteed by our excellent After Sales Service. For “just-in-time support”, all our systems are equipped with remote maintenance access.
