Abstract

The invention relates to the printing industry, in particular, to devices for cutting a sheet of sheet metal. The aim of the invention is to enable the fabrication of a device for cutting a stack of sheet material at the expense of a changeover operation in i.Mcne knives. The device for cutting syupa of sheet paper material comprises table 1, ba, 1ku clamp 2, marzan 3 and knife-holder 4 with knife 6. On the side of the knife, in the holder, grooves are made in which permanent magnets 7 and electromagnets with cores and catupzha are mounted. - mi. Electromagnets are connected with the possibility of polarity change, and their cores are azmei1eni in the grooves of the knife holder so that the side faces of each groove are their holes. yourself. By approaching the cut foot, the knife 6 is held by permanent magnets 7. Before cutting into the electromagnet | 1 | the voltage is applied in such a way that the magnetic points of both types of magnets are added together. When changing knives, the magnitude of the electromagnet is reversed, which makes it easy to remove the knives. 4 il. € (L with O1 N5 CO W; vx-: - v3; V-N ..,:: "M
