Tubing expansion made easy: continuous T-piece shaping

It is often the case that expansion results in an outlet tube with a smaller diameter. But in the example of this shaped aluminium tube (22 x 1.0 mm), both diameters are identical.

Innovative developments by transfluid make processing of tubing more cost-effective: transfluid has again pushed forward the boundaries of technology in the form of its automatic machine for the shaping of tubing. Thanks to imaginative developments in engineering techniques it is now possible for the first time to create non-tool-based, CNC-controlled profiles. In addition, the engineers at transfluid have also provided the option of working with tubing chuck sizes of less than 0.5 x D and to cut and shape these - all in one single work process.

The latest brainchild in the field of continuous shaping of tubing generated by the team based in Schmallenberg in Westphalia in Germany involves the use of an 'SRM'-type machine to expand tubing (T-pieces) with the help of very simple tools. This continuous shaping machine can produce items in both horizontal and vertical designs to meet the needs of individual applications and requirements. All functions are operated servo-electrically and can also be CNC-controlled as necessary.

Increased demand for flexible production processes
Stefanie Flaeper, CEO of transfluid, has this to say about the new system: "Our 'SRM' machine for continuous shaping of tubing can be modified and is thus highly flexible irrespective of whether it is employed for non-tool-based shaping or, as in this instance, for the expansion of tubing. And it is the flexibility that is an important feature of our development concepts that our customers find particularly attractive."

The company is also responsible for innovations with regard to axial tube forming, specifically in connection with tool technology, and these result in improved quality and output. "Multiple shaping operations of a tube end can be undertaken with the help of our pneumatically opening segment tool," explains Stefanie Flaeper. transfluid has equipped these tools with a pneumatic system that controls and opens elements and can verify their positioning. "With our special tools for tube forming, we have managed to ensure that the external surfaces of tubing remain untouched during the shaping processes so that there are no scratches or friction deposits on surfaces. This is because our tools open and close as appropriate to the required position during shaping."

Cost-efficient tool systems
By combining flexibility with the frequently required lightweight construction concepts, especially those of the automotive industry, transfluid has built tool systems with which it is possible to prepare tubing in specific wall thicknesses. This is a particularly efficient solution because it means that thinner tubing can be employed and the wall thicknesses can be created that are required for further processing for use in the various applications.

But in the case of transfluid, flexibility also means in this context that shaping can be first undertaken before the tubing is bent, an approach that relies largely on the availability of the suitable tube bending technology. And this technique also saves money as it is thus no longer necessary to use expensive spanning devices for forming while outgoings for internal logistics operations, handling and loading are reduced. Not only this, but transfluid is also able to provide tube bending machines with an automatic clamp set changer, something that is of additional benefit in situations in which multilevel tools are being employed.

transfluid intends to systematically continue with its current developments in tubing shaping and bending technology with the aim of making tube processing even more efficient.
