Reducing / Expanding
The tube is clamped during the forming operation by min. 2 clamping chucks. A guided reduction ring resp. expanding mandrel is pushed over the tube end and the work piece is expanded / reduced. GFU prefers a closed machine housing which grants:
- longevity of the machine
- continuous high precision of the parts
- easy access to tools
- best run-out percision because outside guided tools
Automatic tool changer available for optional multiple process.
Performance
The required pressing force for each single type of parts is calculated first to choose the respective type of press.
The drive train of the machines are servo-hydraulic, hydraulic or PLC driven.
To enable a highly flexible part handling this is customized to the concept of the production line.
- Weight optimization: Reducing / expanding allows a specified distribution of the wall thickness for weight-sensitive components e.g. for car applications. Frequently the reducing / expanding technology is the economic alternative to rotary swaging.
- Safety: Reduced or expanded parts always are showing homogeanous fibre flow. Related to machined parts, this non-interrupted fibre flow brings higher strength to the components.
- Konzepts: With our know how we are at your disposal to guide you during establishing new production concepts based on GFU reduction and expanding technologies. Beside of feasibility check we propose the new machine concept up to the delivery of a complete and turn-key production line including all needed units.
- Reducing of single components: Work pieces which used to be welded of several single pieces can be produced using pipes as pre-product. This creates a massive cost-reduction on storage cost for single components.
We are at your disposal to support you in creating new production concepts based on GFU forging / swaging technologies. Beside of feasibility check we propose the new machine concept up to the delivery of a complete and turn-key production line including all needed units.
