Pri štancanju elektropločevine opazimo spreminjanje trendov, predvsem v zmanjševanju debeline pločevine in vse kompleksnejši obliki lamel. Zaradi tega se v proizvodnji srečujejo s problemi pri odvajanju odrezov, ki jih povzroča namagnetenost orodja. Povečanje namagnetenosti v prebijalnih orodjih (pestičih) in še posebej v odprtinah za odpadke velikokrat vodi do magnetnega lepljenja feromagnetnih ostankov prebijanja. Cilj diplomske naloge je ugotoviti, kako se lahko posamezne komponente orodja za hitro štancanje namagnetijo, in določiti, kateri način razmagnetenja je najbolj učinkovit in kako pogosto je potreben za nemoteno hitro štancanje. Za zaznavanje namagnetenosti bodo uporabljene različne merilne naprave za merjenje jakosti magnetnega polja (Gaussov meter). Rezultati merjenja namagnetenosti orodij bodo omogočili ugotoviti glavne vzroke za njihovo namagnetenost in najbolj učinkovite načine razmagnetenja.

Title:	ANALYSIS OF THE INFLUENCE OF TOOL MAGNETISATION IN STAMPING OF ELECTRICAL SHEET METAL
Abstract:	The thesis is based on the optimisation of a high-speed stamping process for electrical sheet metal using complex multi-row progressive tools. In the stamping of electrical sheet metal, we observe changing trends, especially in the reduction of sheet thickness, and the increasingly complex shape of the lamellae. As a consequence, production is faced with problems in deburring caused by the magnetisation of the tool. Increasing magnetisation in punching tools (hubs) and especially in the scrap holes often leads to magnetic sticking of ferromagnetic punch debris. The aim of the thesis is to determine how the individual components of a rapid punching tool can be magnetised, and to determine which method of demagnetisation is the most effective, and how often this is required for smooth rapid punching. Different magnetic field strength measuring devices (Gauss meters) will be used to detect the magnetization. The results of the magnetization measurements will be used to identify the main causes of the magnetization of the tools, and the most effective demagnetization methods.
