XRK 2-180 STRAIGHTENING MACHINE MODERNIZATION
Jonáš J., Pokorný Z., Ficek F.
pages 251 - 254, full text

The manufacturing program of ZDAS, a.s. includes the straightening machine of XRK type. The XRK 2-180 straightening machine is an energy-intensive one. Within the framework of the innovation of this type of the straightening machine we have made its new design so as to improve the machine parameters, to reduce the prices and the energy-demand factor. The designed straightening machine XRK 2-180 was computer-simulated and checked for strength using the program MSC.MARC. The features of the innovated straightening machine are as follows: increase of speed by 20%, reduction of the energy-demand factor by 27.3%, reduction of weight by 7,4%, decrease in cost by 8.6%, and the average improvement by 11.2% as to the parameters of the range of products to be straightened.
