Paper Abstract

This article discusses the topic of the monitoring of the operating condition of the pressing machines. In the process of pressing there are a large acting of the forces of the press machine on the machined material. It is accompanied by an expression of deformation of parts of the pressing machines. Knowledge about the resulting loading is important for the final product quality and durability of these machines. In the case of multi-columned presses is important even load distribution among the individual columns. For this reason, it is necessary to monitor the load of the hydraulic pistons. Conventional approaches of load monitoring utilize piezoelectric sensors and strain gauges, which are sensitive to electromagnetic interference, require electrical power, subject to corrosion and action of moisture. A suitable alternative is the fiber Bragg gratings (FBGs) sensors, that those failures have. Their use for load monitoring production presses have been verified by the real measurement on a four-post hydraulic press ALPHA 4 from the company FORM + TEST Seidner. For measurements were used the FBG sensors and classic foil strain gauges (reference). Real measurement was performed during a load of press in the range from 0 to 2000 kN with a step of 500 kN.
