“With this patented method, the machine bends even the most complex isometrics.” This opens up a large variety of application options in profile processing. The company will also show its newly developed machine control. In addition to its easy operation, the synchronous control of the individual machine axes contributes to time-optimised production. In the case of multi-stack machines, for example, the transaction times between two bends are reduced to a minimum. “Today, the processes in the manufacturing industry have to run faster, more cost-effective and more individualised,” said Hartmut Stöhr, the other managing director. “That’s why we paid attention to simplified operation and intelligent linking of control software and machine during the development. Extremely economic processes and low error rates are the result.”

Germany IN 2003, Sikora presented the X-ray measuring device X-RAY 2000 for the first time – the predecessor of the current X-RAY 6000. The system has been successful for 11 years and offers hose and tube manufacturers a continuous quality assurance, combined with increased productivity and long- term cost saving. Producers of hoses and tubes are facing global competition and are especially measured in terms of their product quality and reliability. An important aspect in this respect is the continuous measurement and control of the wall thickness, the eccentricity and the inner and outer diameter of the product.

U- and O-forming presses at Tenaris Confab

welded pipeline pipes, the company ordered a 500 MN O-forming press for its location in Pindamonhangaba, São Paulo, in 2011. The company later ordered an 18 MN U-forming press. Siempelkamp says that the customer was highly satisfied with the results of the first press cycles and felt reassured with its decision to have selected a Siempelkamp concept. With both presses, Tenaris will produce grade X70 pipes with a wall thickness of up to 55mm and an external diameter ranging between 12¾" and 48". The presses will also allow material grades X80 and X100. The 500 MN O-forming press is equipped with five main cylinders, and applies a force of 40,000kN per metre. Combined with Siempelkamp’s patented multi-cylinder parallelism control, the control ensures that the moving beam maintains a position parallel to the press table within a tolerance of ±1mm over the entire length. The modular tool concept reduces the tool costs per pipe diameter. The 18 MN U-forming press replaces an old 9 MN U-forming press from the 1970s. With an automated tool change system and an automated clamping system for tool segments, the setup times are reduced. A special feature for both presses is their energy-efficient drive system. For the basic movement of the moving beam of the O-forming press, the oil-hydraulic drive was equipped with variable-speed high-pressure pumps. With this control concept the potential energy as well as the energy stored inside the elasticities during the forming process can be recovered. The energy is then fed back as electricity into the supply network. Due to the variable-speed high- pressure pumps, the U-forming press also achieves high energy efficiency. At any time, the amount of energy used is the actual amount needed for the forming process.

The new, easy-to-operate machine control from Schwarze-Robitec

The company integrated another advantage in the form of a diagnostic and maintenance tool guiding the user through all setting and optimisation steps. At their stand, Schwarze-Robitec specialists will provide information about current industry trends, new developments, and the Schwarze- Robitec product and service range.

The X-RAY 6000 celebrates its 11 th birthday

Continuous and control is the basis for the reduction of production costs, start-up scrap and rejections due to a lack of quality. For online quality control during hose and tube extrusion, Sikora offers the X-ray measuring device X-RAY 6000 and the high-end series X-RAY 6000 PRO. The X-RAY 6000 is particularly interesting for production lines where only products with single layer, resp. the total wall thickness have to be measured. It is a cost-effective and at the same time very powerful measuring device for the continuous measurement of the inner and outer diameter, wall thickness and eccentricity. measurement
