Process optimisation in bending and end forming

robots, punching units, shearing and cutting devices, optical and vision measuring systems, and automatic solutions to load, unload and handle the tubes. In some applications there is a need to bend pipes with blocks or pre-assembled flanges at their extremities, which must be properly orientated before facing the bending process. Previously, the only solution to bend this kind of product consisted of using customised tooling to bend each pre-assembled pipe. Crippa has designed a new loading device based on a vision system that orientates the tube without changing the bending tooling. This system is based on the use of cameras that detect the piece coming from an automatic feeder and compare it with the planned and programmed image of the piece. The cameras communicate directly with the bending machine, indicating how to correct the position of the tube and how to orientate it correctly. The machine performs the required operations and and a simultaneous increase in quality of the products made. Modern drive technology and innovative machinery concepts in addition to a high degree of automation allow for faster production speed and higher availability of the line. The placement of all equipment in-line and the resulting elimination of manual material handling between the individual components of the line resulted in significant reduction of scrap. The customer benefits from ASMAG’s quality and consistent manufacturing standards, a single point of contact, and

TUBE bending and end-forming processes consist of several operations that increasingly require the integration of transverse and complex technologies and expertise. Many manufacturers limit their offering to standard productive solutions, leaving the customer the responsibility to optimise the process within limits imposed by budget, logistics and time scheduling. For Crippa, the customisation of machinery is a critical question for the development of new products. 40 per cent of the company’s resources are in the R&D department, fully engaged in supporting the customer in the choice and integration of the best available technologies to realise their products. Where there are high production volume requirements, the company realises transfer machines, aimed at achieving the best cycle times and the maximum feasibility and repeatability. In addition to tube bending and end- forming machines, Crippa integrates

the tube is placed in a perfect position. Crippa’s Easy Position technology allows just one toolset to bend different preassembled tubes. In addition, set-up times are reduced, as there is no need for time-consuming tooling changes. Crippa’s Easy Position technology uses cameras to detect the incoming workpiece and compare it with the planned piece

Complete production line for steel tubes TUBE mill equipment supplier ASMAG has shipped a complete line to manufacture up to 4" high-precision steel tubes to a customer in the USA. The comprehensive line comprises a fully automated 600kN triple draw bench with integrated pointing machine, and a fully automated finishing line consisting of a ten-roll straightener RRM-pro-100/10, testing table, multiple sawing line, chamfering units and a stacking, bundling and banding system. Smallest induction bending machine CB&I Cojafex BV, which has a well- established reputation for its induction bending machines for large pipe sizes (48", 56", 64" and above) and heavy wall benders (up to 6" wall thickness), has introduced its smallest machine to date. This innovative new 1" to 4" bending machine is capable of producing spool pieces in carbon, alloys, stainless and duplex grades in pipes with a length up to 6m. The highly automated machine has been installed at NIRAS in Norway, at The requirements of the line were to achieve savings on production costs ASMAG GmbH – Austria Email: sales@asmag.at Website: www.asmag.at

seamless integration of all machinery, equipment and components into a reliable, comprehensive line. ASMAG components, machinery and equipment are exclusively manufactured at its plant in Austria. Together with Seuthe, the ASMAG group focuses on equipment for the manufacture of steel and non-ferrous metal tube, pipe, profile and bar products.
