The right tool for the best moulding IN the development of moulding tech- nologies versatility is a common chal- lenge depending on the sector and the use of the tubes, according to transfluid Maschinenbau GmbH. “So, for instance, our upsetting technology could be in demand, with the upsetting capacity of 98kN, 147kN or 196kN,” says Stefanie Flaeper, managing director at transfluid. “Or our roller technology, that facilitates tooling-independent moulding with only one tool. Even combination machines that display the axial and roller moulding in a tube clamp are potentially necessary.” In order to secure powerful results it is important that the tools used during the procedure guarantee the design of every individual tube product. The rigorously customised tool development undertaken includes feasibility studies and, if necessary, a sample production and prototype. An entirely new department has been created to cater to the latter, where specialists inspect components and tools of up to 45mm diameter. Tool design is an especially relevant topic even for axial tube moulding. For

instance, as far as the cycle time allows, transfluid often inserts an intermediate clamping unit in hose connections. It provides internal support for the entire geometry. The technology prevents the tubes from bending inwards at sensitive locations. In the case of multiple upsets that cannot be produced in the above- mentioned manner, transfluid uses a single-tier sliding split mould. These tools are equipped with an internally controlled pneumatic guard lock. This prevents scratches from forming on the geometry if clamping claws are opened after the moulding. The position of the sliding element is always recognised. A technical feature concerns the upsetting tools that open up when the moulding tier moves back and forth. In the case of longer strokes they prevent contact between material and tool. Thus it prevents cold welding between tool and material and the surface of the material remains undamaged. Multiple beading along with an intermediate clamping fixture can also be produced using this technology. transfluid Maschinenbau GmbH – Germany Fax: +49 2972 9715 11
