(54) SCISSORS

one

The invention relates to the processing of metals by pressure and can be used in machine building for cutting sheet material.

Scissors for cutting sheet material are known, comprising a housing, in the guides of which a slide is mounted, an eccentric drive shaft mounted in the supports of the housing and a slide with a slide, a fixed knife fixed on the lateral surface of the housing 3

A disadvantage of the known scissors is that in the case of regrinding the knives, it is also necessary to rewind the additional elements of the scissors in order to maintain the necessary gaps between the knives, which leads to additional time spent on changing knives.

The purpose of the invention is to increase productivity by reducing the time for changing knives. still

25 is attached to the side surface 9 of the housing 1. The surface of the strip 6, to which the movable knife 7 is attached, lies in the same structure with a surface 9 of the housing 1.

30 Scissors work as follows. The workpiece is placed between the blades 7 and 8 and the handle 3 is turned. The eccentric shaft 2 moves the slider down and cuts the workpiece. After replacing the knives 7 and 8, the gap between them does not change, so it is not necessary to additionally adjust the gap with gaskets or regrinding guides, which allows for an increase in the productivity of the shears.
