Euroblech 2014 In punching, the focus is on servo technology and gentle processing

Editor: Barbara Schulz

The increase in exhibitors and visitors at Euroblech indicates the demand for individual solutions for sheet metal processing, which is also true in punching. With resource conservation and lightweighting in mind, demand for effective installation technology is high.

Whether in medical technology, the automotive field, electrical engineering, electronics or rack and storage technology, the need is not simply for sheet metal parts to be punched as accurately as possible, but production sequences should also be effective and time-saving. The manufacturers of punching installations are responding with appropriate machines and numerous developments, which are being presented at the Euroblech show in Hanover, Germany, on 21-25 October.

Haulick+Roos GmbH has been represented in Hanover for more than 20 years, and it is exhibiting again this year. The company offers mechanically-driven precision automatic punching and forming machines with cycle rates of up to 400 cycles per minute, and precision high-performance automatic punching machines with cycle rates of over 1000 cycles per minute, each with its own peripheral equipment. “We are presenting innovations in the area of servo technology and further developments of an existing press series,” said Markus Roos, an executive partner at the firm. “The highlight will be the presentation of the further developments in our innovative ROP series for the higher pressing force range and of further optimisations of customer-utility due to our innovative servo-drives.”


Servo technology is the core topic in forming technology

Ebu Umformtechnik, a manufacturer of automatic punching machines, feeding technology and eccentric presses, also sees servo technology as a core topic. Replying to a question about visitors’ expectations at this year’s Ebu stand, Jörg Berger, an executive partner said: “The emphasis at this year’s fair is on the area of automatic punching machines in the upper nominal power range and specifically on servo technology.” Roos underlined the key function of this type of drive. Looking at forming technology as a whole, he sees a further rise in the performance of servo-drives coupled with a conserving approach to energy resources as the major future trend. In his view, also important is the integration – made possible by servo technology – of further work steps for parts that need bending or stamping or in which operations such as welding or thread forming are carried out in the tool.

Installation constructor Andritz Kaiser has already been an exhibitor at the Euroblech for decades, and the firm is once again on hand with customer-specific applications. Wolfgang Wiedenmann, deputy sales manager and responsible for marketing and publicity, previewed the show: “The central point will be the presentation of our latest generation of automatic punching/forming machines. We will be showing a servo-press with 2000 kN pressing force in the proven solid casting version. The highlight of our presentation will be our new, modified plunger guidance system for automatic punching machines, developed specially for applications subjected by the tool to high non-centred forces.”

Developers of punching installations are unanimous: there is no future without servo technology and efficient drives. This is clear at press-builder Schuler. Stefan Klebert, board chairman, said, “Visitors to the Schuler stand will see for the first time an automatic punching machine in the 200 t class with completely new drive technology.”
